When you see running workouts, you may see terms like “sprints,” “easy jog,” “fartleks,” “intervals,” “gassers,” and even “goal-pace running.” They all are references to different types of pace workouts, and they are all different — some more different than others.
It is easy to get confused as to how you should train for timed runs, especially if you are new to running, have recently lost weight, still have weight to lose, or need to pass a fitness test.
Here is an email from a young man who has made tremendous progress with both running and weight loss:
Stew, I need to pass a 1.5-mile fitness test run and get my time below 12 minutes (11:58 is the slowest I can go). I am currently at 13 minutes but have dropped from 16 minutes as well as 25 lbs at the same time. I still have some weight to lose but within the standard. Any recommendations? Still trying.
Great job with dropping mile pace and weight! Those are great accomplishments and show you have been really working hard. The good news is you do not need to change much of your current effort, but you do need to start training to run at a faster pace in order to achieve the next set of goals. And maybe you can lose some more weight too (which will make you faster).
Here is how I would do it:
Evaluate how much you are running per week now, and keep it at that mileage, but do it at a faster pace. You can run every other day with non-impact cardio activities like bike, swim, elliptical in place of running if you feel your joints, shins and feet need a break from the impact. But if you are feeling fine, try the following:
Your new goal pace is to be able to run a quarter mile in less than 2 minutes. You do not need to run it in 1:30 or even 1:45; instead, learn how to run each lap of the following workout at 1:55-1:58. This will give you a few seconds of “gravy time” in case you slow down on the last few laps, but is not so fast that you blow all of your energy out in the first lap as many people do. You have to think GOAL PACE strategy.
Here is the workout:
Run 1/4 mile warmup — any pace/stretch
Repeat 8-10 times:
Run 1/4 mile at goal mile pace (1:55)
Optional: Rest with another quick exercise for 1 minute (situps, pushups, squats, lunges) Alternate above “rest exercises” every other set if needed, or skip altogether.
I recommend the above workout 3 days a week, every other day. On the days in between, you can opt to do more running or non-impact cardio. However, the goal is different. Push yourself on these shorter/faster runs to help build your overall cardiovascular conditioning and speed. Mix in sprints, intervals, shuttle runs and fast/slow fartleks however you prefer. If you run, limit the distance to maybe a mile but you do a series of 50m, 100m, 200m and 300m, and 400m sprints.
Warm up with a fast 400m or 2-minute bike/light stretch.
Increase speed each set and avoid full sprints if you are getting older, have had some issues with tight hamstrings/calves, or previously had pulled hamstrings. But you can still run faster than your goal pace above. That is the goal of the days in-between. Get winded each set and rest by walking back to the starting line.
Repeat 5 times
50m fast runs — build up to full speed by set 4 or 5 (close to full speed)
Walk back to starting line
Repeat 4 times
100m fast runs — build up to full speed (after a few sets)
Walk back to starting line
Repeat 3 times
200m fast runs — fast — much faster than 1 minute (half lap)
When ships are fighting, the battles can take a long time. To give one example, the battle between a German wolfpack and convoy ONS 92 lasted from May 11 to May 14 — three days of constant ASW. Combat can take a toll on a crew, but so can not eating.
Today, it runs a little differently, given the higher expectations that sailors have about their food. Let’s look at one of the newest warships in the Danish Navy, the Iver Huitfeldt-class frigate HDMS Peter Willemoes. This frigate is powerful, carrying 32 RIM-66 SM-2 surface-to-air missiles, up to 16 RGM-84 Harpoon anti-ship missiles, 24 RIM-162 Evolved Sea Sparrow Missiles, a pair of 76mm guns, and a 35mm close-in weapon system. It also can operate a MH-60R helicopter and carry up to 165 personnel.
So, how can they quickly feed that crew, while still keeping a combat edge? Well, for one thing, the crews don’t get a lunch hour — they get six minutes to eat. That restriction means that the cooks can fix that meal and clean everything up in a grand total of 74 minutes.
As a result, that crew is refueled and ready to take on the enemy, whether in the air, on the surface, or underwater. The video below helps show how this is done – quickly and efficiently, so this ship can fight!
Star Wars: The Rise Of Skywalker | D23 Special Look
Of course, the most buzz-worthy scene is “Dark Rey” wielding a duel-bladed — and red — lightsaber. I don’t want to fansplain to you or anything, but red blades are of course associated with the Sith, who often preferred synthetic crystals energized by the dark side of the force.
Rey’s blade could mean a number of things. Maybe she nicked it? Maybe she turned to the dark side? Or probably maybe it’s just a vision. Rey hasn’t had a character flaw yet, but who knows? Maybe J.J. Abrams wants to throw us a curve ball.
(PS: Has anyone else noticed how dangerous these fancy lightsabers are? Like, how does Kylo Ren not chop his leg off any time he ignites his crossguard lightsaber?? The Force can only do so much…)
I just want to know that he attended his safety brief.
Anyway, back to Rey.
Twitter user Alan Johnson has a different theory about Dark Rey:
I still think Rey is a clone and the Sith version from the new The Rise of Skywalker trailer is a clone that has been activated and possessed by Emperor Palpatine. The vision she had in The Last Jedi screamed “clone” to me at the time.pic.twitter.com/ztoM5sqJmZ
Now that would be interesting to me. And I’m going full nerd to tell you why.
A brief history on clones in the Star Wars universe: they were bred to fight as soldiers under their Jedi commanders during the time of the Republic (think prequels). Under Supreme Chancellor Palpatine, the clone troopers fought the droid army of the Separatists during the Clone Wars.
But there was a hidden trigger implanted into every clone, and Palpatine (who of course we know was a Sith), issued Order 66, which named the Jedi Knights enemies of the Republic and called for their eradication. The clone militants purged the galaxy of the Jedi and gave Palpatine unchecked control of the Republic, allowing him to become the true antagonist of the original trilogy.
Emperor Palpatine was thrown into a deep shaft by Darth Vader during the Battle of Endor —presumably dead — and yet promo materials for the Rise of Skywalker have been teasing his return.
Could Palpatine have survived his fall? I’d say yes — any trained Force-user can levitate so it’s far-fetched for them to fall to their death. Theoretically he could have also hidden himself for all these years.
If he is alive, and Rey is a clone, that could pose many questions. Is Dark Rey also a clone? Could Palpatine “Order 66” her? Are there more versions of her? (I mean, I wouldn’t be unhappy with an Orphan Black situation…)
As a fan, it’s fun to consider the possibilities, which makes The Rise of Skywalker even more fun to look forward to.
Described as “the bravest man you’ve never heard of,” Captain Humbert Roque Versace’s story is one that is not as well known as it should be. So allow us to remedy that by discussing how he spent two years basically being a huge pain in the ass for his captors in a Vietnamese POW camp — so much so that he managed to become the first person in the U.S. Army to earn a Medal of Honor for his conduct as a prisoner of war.
Born in 1937 in Honolulu, Hawaii, Versace was the son of decorated army colonel, Humbert Joseph Versace, and famed author, editor, and pilot Tere Rios, who, among other things, wrote The Fifteenth Pelican, which would inspire popular 1960s TV show The Flying Nun.
The oldest of five children, “Rocky” as he was known was a smart and headstrong child who would later be described by his brother, Steve, as being “infuriatingly opinionated” and “If he knew he was right, he was absolutely atrocious…” — a trait that played a role in his earning a Medal of Honor.
Like his father before him, Versace joined the army, attending West Point Academy in 1959 and graduating with honors. Over the next two years Versace received training as both an Army Ranger and a parachutist, eventually rising to the rank of Captain during a tour in North Korea as a tank platoon leader. In 1962, the newly minted Captain Versace was assigned to serve in a mostly ceremonial role with the distinguished Old Guard at Fort Meyer. Soon enough, however, he volunteered to serve in Vietnam.

Prior to being shipped off to Vietnam, Versace received yet more training, this time to become an Intelligence Officer. As part of his training, he received a crash course in Vietnamese, a language he was fluent in by the time his tour of duty began in May of 1962. This, combined with Versace’s fluency in French, made him an invaluable asset to the Army and incredibly popular with the South Vietnamese forces and civilians of the Mekong Delta.
His fluency in Vietnamese was important to Versace as his dream was to eventually become a Catholic priest and missionary to the people of South Vietnam. Thus, Versace spent much of his free time as a soldier there volunteering at local orphanages, assisting townspeople and securing vital and not-so-vital supplies to make life a little easier for the locals. In regards to the latter, in addition to securing food and building materials, Versace also continually wrote letters to schools in the United States asking for toys and learning materials for the children of the villages he visited.
A year later, with his tour of duty coming to an end, Versace applied to stay in Vietnam for another 6 months despite receiving news that his application to seminary had been accepted. As it would later emerge, Versace had decided that he still wanted to be a priest but his decision to embark on a second tour of duty was born out of an earnest desire to continue helping the orphans he’d become so attached to during his time in the country.
Two weeks before this second tour was set to end, Versace volunteered for a highly dangerous mission to assist South Vietnamese troops take down a North Vietnamese command post located deep in the U Minh Forest.
During the mission Versace and his fellow soldiers were ambushed and overrun by Viet Cong forces. Hopelessly outnumbered, he called for a tactical retreat, along with First Leiutenant Nick Rowe and Sergeant First Class Dan Pitzer, covering the exit of South Vietnamese soldiers with sustained rifle fire as a hail of bullets tore overhead. During the ensuing firefight, Versace was hit in the back and legs by bullets and shrapnel as he stood, completely exposed to the hellstorm raging around him firing his weapon into jungle.
Running low on bullets, Versace charged the enemy in an apparent effort to single-handedly beat them all to death with the butt of his rifle. During his charge, he was injured once more, falling to the ground and being quickly set upon and beaten by the enemy forces.
After being physically overpowered, Versace, along with Pitzer and Rowe, were stripped of their weapons and boots, before all three were marched barefoot into the jungle towards a POW camp…. Which is when Versace got mad.
Remembering Captain HR ‘Rocky’ Versace on Memorial Day 2016
For the next two years Versace made life for his captors hell as they tried and failed to do the same to him. Strikingly handsome with a tall, imposing frame and a magnetic personality, Versace became the pseudo-leader of his fellow POWs. Frequently tortured and interrogated, he refused to give them any information and relentlessly badgered his captors about their treatment of his friends and comrades, citing articles from the Geneva Convention and using his time in isolation to think up ever more creative insults.
Tired of his antics, in an effort to keep him away from other POWs, Versace was eventually locked inside of a bamboo cage away from everyone else, which didn’t stop him from boosting the morale of everyone around him by cheerily singing pop songs. When the Viet Cong locked Versace in an isolation cage even further away from the rest of the POWs, he just sang louder. When they began gagging him so that he couldn’t speak or sing, he started leaving messages of support in the toilet.
Not content to just sit around singing, during his imprisonment, Versace escaped four times, each time being captured not long after. In the first instance, he was so severely injured at the time that he couldn’t walk, but instead crawled away from the camp in agonizing pain through marshland. As you might imagine, it didn’t take the Viet Cong very long to locate him once they’d discovered he’d managed to escape.
Each time he was recaptured, Versace was noted as telling his captors that he’d do it again the first change he got, prompting them to redouble their efforts to break him. As you can probably guess by now, these efforts failed miserably.
At first the Viet Cong tried “re-educating” Versace, attempting to brainwash him with political propaganda. Versace reportedly spent much of his time during these sessions loudly arguing with his indoctrinators.
Along with inspiring his fellow POWs, this saw to it that the bulk of his captor’s frustrations and anger were directed towards him, something his fellow POWs were also reportedly very grateful for. As noted by President George Bush some four decades late, “By focusing his captors’ anger on him, he made life a measure more tolerable for his fellow prisoners, who looked to him as a role model of principled resistance.”
Humbert Versace’s memorial plaque outside MacArthur Barracks at West Point.
In addition to inspiring POWs, Versace’s tenacity inspired the people of Vietnam; when the Viet Cong tried to parade a beaten and bloodied Versace through local villages, he’d offer words of encouragement in Vietnamese to those gathered. This was much to the annoyance of the Viet Cong who’d warned against such insubordination by threatening to viciously beat him within an inch of his life if he did so.
Frustrated with their inability to break this man, the Viet Cong eventually made the decision to execute Versace. When he was informed of this, he reportedly responded by singing God Bless America for 5 hours straight the night before his execution was to take place. This song was the last thing any of his fellow prisoners ever heard from Versace.
Following through on their threat, Rocky Versace was executed on Sep. 26, 1965. His body was never recovered, but a headstone was placed above an empty grave in Arlington National Cemetery.
For his conduct as a POW, initially Versace only received a silver star, the Army’s third highest award. This was something his fellow soldiers didn’t feel reflected the full extent of his actions and sacrifice while a POW, resulting in a concerted effort from a “hodgepodge group of soldiers and civilians” aware of the full details of what Versace endured to see him awarded America’s highest military honor.
In 2002, this request was finally fulfilled, with one of Versace’s brothers, Dr. Stephen Versace, accepting the medal from then President George Bush. In his speech, Bush noted:
In his defiance and later his death, he set an example of extraordinary dedication that changed the lives of his fellow soldiers who saw it firsthand. His story echoes across the years, reminding us of liberty’s high price and of the noble passion that caused one good man to pay that price in full.
In addition to being the first American POW to earn a Medal of Honor for his conduct during his time as a prisoner, Versace is an inductee in the Pentagon’s Hall of Heroes as well as a member of the Ranger Hall of Fame.
Said his former fellow prisoner Sergeant Dan Pitzer of the man himself,
Rocky walked his own path… for that guy, duty, honor, country was a way of life. He was the finest example of an officer I have known… Once, Rocky told our captors they might as well kill him then and there if the price of his life was getting more from him than name, rank, and serial number… He got a lot of pressure and torture, but he held his path… He was brutally murdered because of it… I’m satisfied he would have it no other way…. [He] valued that one moment of honor more than he would a lifetime of compromises.

There were a number of unwritten rules among the men who fought the American Civil War. Confederate soldiers were known to execute white officers who led black men in combat. While that certainly is terrible, Confederate troops also refused to use landmines, believing them “ungentlemanly.” Meanwhile, the Union Army practiced “total war” against the South, destroying the property and livelihoods of soldier and civilian alike while at the same time adhering to the Lieber Code, an early law that governed warfare much the way the Geneva Convention later would.
There was one thing, however, the soldiers on either side of Civil War battlefields would not do – they would not shoot a man relieving himself. And for a good reason.
There’s a good chance they’ve all had dysentery.
The biggest killer of Civil War soldiers was not the bullet, sword, or cannonball, it was disease. For every American troop who died at the hands of the enemy, two more would die of disease. The most likely culprits were typhoid and dysentery. The clear winner was dysentery, and it wasn’t even close. Dysentery and the diarrhea that came along with it ravaged both Armies for the entire war. It was this disease and its signature symptom that claimed more lives than all the battles of the war, combined.
It wasn’t the doctor’s fault, they actually had no idea what caused such diseases at this time in American history. The necessity of sanitation and hygiene among such large groups of people was not fully understood at the time. Doctors didn’t actually know about germ theory or how disease actually started. Camps were littered with refuse and whatnot in various states of decomposition. Soldiers lived close to their latrines, along with the manure from the army’s animals. An estimated 99.5 percent of all troops caught dysentery at some point.
With how much the disease affected both sides of the war, another rule to the war’s unwritten code of conduct emerged. No soldier would ever take a shot at a man relieving himself of the primary burden of the disease – or in the words of one Civil War soldier’s letter home, “attending to the imperative calls of nature.” when they rejoined their unit, of course, they were fair game.
Doctors did what they could to treat the illness, but given that they didn’t know bacteria existed, let alone the dozens or more that could cause gastrointestinal distress, it hardly did the job. Usually, troops were treated with opium. Not a terrible way to get back to duty but also not quite a cure, either.
Did anyone in your high school complain about gym rats and “show muscles”? Well, there’s not really any such thing as show muscles in the military. Every fiber can make you more lethal, whether it’s the biceps to curl a tank or artillery round that’s about to be thrown into the breech, or the hamstrings to make it through a long patrol.
But think about how badly it will suck for the Space Force. They need to keep those muscles strong enough to beat Martians to death with hammers and wrenches on a moment’s notice, but they need to fuel those gains with freeze-dried foods while working out in low gravity.
Solar Foods’ technique was originally pushed by NASA and is now supported by the European Space Agency. The basic idea is to pull carbon dioxide from the atmosphere, combine it with water as well as some additional nutrients, and turn it protein. The final product is a single-cell protein that can be used like traditional flour. It’s 50 percent protein, up to 10 percent fat, and up to 25 percent carbohydrates.
The entire process only needs a little infrastructure, some electricity, water, and carbon dioxide, so it could potentially be used at bases around the world or in space flight. (The European Space Agency specifically got involved in the hopes that the process could work en route to Mars.)
If you want to get your hands on this high-protein flour, you’ll have to wait till 2021 and, even then, hopefully, be stationed in Europe. That’s when and where the company plans to start its commercial launch with global access coming later in the year.
“We will never tolerate threats from anybody. Rule of law is for everyone; no exception,” he wrote.
Trump’s comments come an hour after Vice President Mike Pence issued a similar threat, warning of “significant sanctions” against Ankara.
“To President [Recep Tayyip] Erdogan and the Turkish government, I have a message on behalf of the president of the United States of America: Release Pastor Andrew Brunson now or be prepared to face the consequences,” Pence said, speaking at a State Department event in Washington to advance religious freedom.
Brunson, who has worked in Turkey for more than 20 years, was jailed in 2016 and was indicted a year later on terrorism and espionage charges, accused of aiding groups Ankara alleges were behind a failed military coup in 2016.
Brunson was held in custody until July 25, 2018, when he was transferred to house arrest.
Secretary of State Mike Pompeo said the move to house arrest was “not enough” and that he should be allowed to leave Turkey.

The Air Force gets a lot of flak (see what I did there?) from all the other branches for its somewhat lax persona. Yes, sometimes, the USAF seems more like a corporation than a branch of the Armed Forces. But despite decent food and living quarters, Air Force, Inc. is still very much a military branch.
There’s more to the U.S. Air Force than the classic stereotypes of high ASVAB scores, delicious food, nice living quarters, and beautiful women. The Air Force deploys. They do see combat. They just have their own unique way about it.
1. We salute our officers before sending them into a fight.
Our pilots — all officers — are the ones putting their asses in the line of fire supporting troops on the ground (troops from other branches, most likely), but the airmen who maintain and marshal those planes are enlisted.
The video above demonstrates something known as “Freestyle Friday” marshaling and, while it may be funny, those crazy marshaling dances still always end with a sharp salute — no matter what. Those pilots may very well not come back from a combat sortie, so respect is always due.
2. We don’t know if we should salute a warrant officer.
The reason for that is the Air Force doesn’t have warrant officers and hasn’t had them since 1992 when the last warrant officer, CWO4 Bob Barrow, retired. The last airman to become a warrant officer did it in 1959.
Does your branch salute warrant officers? How will the Air Force know if no one ever tells us? Do we care? Does it matter? I know airmen who went ten years without ever encountering a warrant.
3. Enlisting in the Air Force gets you halfway to a 2-year degree.
It has its own accredited community college, one that accepts basic training as physical education credits and puts your Tech School training towards an Associate’s Degree. Once at your permanent duty station, you can either take general courses at the base education office or take free, unlimited CLEP tests to finish it off.
Getting a degree from the Community College of the Air Force is so easy that it’s now one of those unwritten rules: Airmen need to have one to get promoted.
4. We don’t have ground combat troops.
The Air Force has its Security Forces, its special operations troops, combat arms instructors, and it even lends airmen of all careers to other branches. Airmen see combat all the time. But the USAF’s regular combat force is aircraft. We don’t have an infantry or anything like it.
5. The Air Force trains hard… just not always to kill.
When you flip a light switch, the lights go on. It seems simple, but a lot of preparation, training, and work went into what happened behind your wall. A JDAM works the same way. Aircraft maintainers, ammo troops, and pilots train relentlessly for years to make sure that kind of support is there when a Marine calls for it.
Just because an airman’s deployed location is a little plush doesn’t mean they didn’t spend eight years of their life training. Watch how fast a flightline can get a squadron of F-22s in the air and tell me airmen didn’t train hard for that.
Cargo containers of coronavirus tests being unloaded from a Korean Air flight.
Maryland has National Guard troops and state police guarding coronavirus tests at a secret location because of concerns that they might be seized, Maryland Gov. Larry Hogan told The Washington Post Thursday.
“We spent about 22 days and nights dealing with this whole transaction with Korea. We dealt with the Korean embassy, folks at the State Department, and our scientists on both sides trying to figure out these tests,” Hogan said. “And then at the last moment, I think 24 hours before, we got the sign-off from the FDA and Border and Customs to try to make sure that we landed this plane safely.”
The Maryland governor said when the Korean Air jet carrying the 500,000 tests flew into Baltimore/Washington International Thurgood Marshall Airport, it was met by National Guard troops and state police.
Hogan said it landed there “with a large contingent of Maryland National Guard and Maryland state police because this was an enormously valuable payload. It was like Fort Knox to us because it’s going to save the lives of thousands of our citizens.”
Maryland @GovLarryHogan on whether he was concerned that the federal government would seize the tests the state procured from South Korea. He says the tests are being guarded by the National Guard at an undisclosed location. https://youtu.be/PjkMyHbyhro pic.twitter.com/15BhHmLzql
Hogan, who is a Republican, said he had heard reports from other states of the federal government confiscating supplies. He specifically pointed to an incident in Massachusetts.
After 3 million masks purchased for the state were confiscated in New York, state leaders in Massachusetts turned to New England Patriots owner Robert Kraft to help bring in coveted N95 masks from China on a private plane.
“There were a couple of other states that had similar stories,” Hogan said.
He said the tests were “so important to us that we wanted to make sure that plane took off from Korea safely, landed here in America safely, and that we guarded that cargo from whoever might interfere with us getting that to our folks that needed it.”
The governor added that the test protection was ongoing, saying that “the National Guard and state police are both guarding these tests at an undisclosed location.”
Maryland’s decision to purchase coronavirus tests from South Korea drew criticism from President Donald Trump, who said the governor could have made use of available labs to help boost testing capacity. “I don’t think he needed to go to South Korea. I think he needed to get a little knowledge, would have been helpful,” the president said at a recent briefing.
Hogan later responded on MSNBC, saying that if there had been “an easier way” to get the necessary tests, “we certainly would have taken it.”
US aircraft carriers are a “tremendous expression of US national power,” and that makes them a target for adversarial powers, the US Navy’s top admiral said Feb. 6, 2019.
“The big thing that is occupying our minds right now is the advent of long-range precision weapons, whether those are land-based ballistic missiles, coastal-defense cruise missiles, you name it,” Adm. John Richardson, the chief of naval operations, said at the Atlantic Council, adding that the systems wielded by adversaries are “becoming more capable.”
Chinese media has recently been hyping its “carrier-killer” DF-26 ballistic missiles, which are reportedly able to hit targets as far as 3,500 miles away. China released footage of the Chinese military test-firing the missile in January 2019.
DF-26 medium-range ballistic missile.
The purpose is to send “a clear message to the US about China’s growing missile capability, and that it can hold at risk US strategic assets, such as carriers and bases,” Adam Ni, who researches China at Macquarie University in Sydney, recently told the South China Morning Post.
“There’s two sides, an offensive part and a defensive part,” Richardson said Feb. 6, 2019, stressing that the Navy’s carriers are adapting to the new threats. “The advent of some of new technologies, particularly directed energy technologies coupled with the emerging power generation capabilities on carriers, is going to make them a much, much more difficult target to hit.”
Speaking with the crew of the new supercarrier USS Gerald R. Ford on Feb. 5, 2019, Richardson said, “You are going to be able to host a whole cadre of weapons that right now we can just start to dream about. We’re talking about electric weapons, high energy laser, high-powered microwave [and] very, very capable radars.”

The expensive billion carrier is expected to be deployed in the next few years.
“Rather than expressing the carrier as uniquely vulnerable, I would say it is the most survivable airfield within the field of fire,” Richardson said Feb. 6, 2019, in response to questions about carrier vulnerability. “This is an airfield that can move 720 miles a day that has tremendous self-defense capabilities.”
“If you think about the sequence of events that has to emerge to be able to target and hit something that can move that much, and each step in that chain of events can be disrupted from the sensing part all the way back to the homing part, it’s the most survivable airfield in the area,” he said.
Richardson said the carrier is less vulnerable now than at any time since World War II, when the US Navy was putting carriers in action, and those carriers were in combat taking hits. “The carrier is going to be a viable force element for the foreseeable future.”
US carriers are particularly hard, albeit not impossible, to kill.
“It wouldn’t be impossible to hit an aircraft carrier, but unless they hit it with a nuke, an aircraft carrier should be able to take on substantial damage,” retired Capt. Talbot Manvel, who served as an aircraft-carrier engineer and was involved in the design of the new Ford-class carriers, told Business Insider previously.
US carriers “can take a lick and keep on ticking,” he said.

Personally nominated for the Nobel Prize a record 84 times, Arnold Johannes Wilhelm Sommerfeld was one of the most influential physicists of all time, both because of his own accomplishments in the field and the many dozens of his students who turned into superstars in the world of science (including having four doctoral students go on to win the Nobel Prize, along with three of his other postgraduate students also taking home the award- the most eventual Nobel laureates all taught by one person).
Born on December 5, 1868 in Königsberg, East Prussia, Sommerfeld began his career as a student of mathematics and the physical sciences at Albertina (aka University of Königsberg) in his hometown, where he received a Ph.D. on October 24, 1891.
After a year of compulsive military service ended in 1893, unlike so many academics of his era, Sommerfeld continued to serve as a volunteer for the next eight years on the side. Physically impressive, with a Prussian bearing and wearing a fencing scar on his magnificently mustachioed face, while in the service, Sommerfeld was famously described as managing “to give the impression of a colonel of the hussars,” rather than a book-worm academic.
As for that scar, in his first year of study, the near “compulsory drinking bouts and fencing duels” not only resulted in said scar, but also hindered his studies significantly, which he later came to regret as wasted time.
Apparently making up for lost efforts in his youth, Sommerfeld left Königsberg for the University of Göttingen and after two years as an assistant to more experienced mathematics professors, he earned his Privatdozent (authorization to teach at the university level) in 1895. Rapidly moving up the ranks, he was appointed to chair the mathematics department at the Bergakademie in Clausthal-Zellerfeld in 1897. The following year, he became editor of the famous Enzyklopädie der mathematischen Wissenschaften, a post he held through 1926.
Sommerfeld moved on to become Chair of Applied Mechanics at the Königliche Technische Hochschule Aachen, and it was in Aachen that he produced his theory of hydrodynamics. Also at Aachen, Sommerfeld mentored Peter Debye, who later won the Nobel Prize in Chemistry in 1936 for “his contributions to the study of molecular structure.”
In 1906, Sommerfeld accepted the position as director of the new Theoretical Physics Institute at the University of Munich, where he mentored Werner Heisenberg in hydrodynamics theory; Heisenberg later won the Nobel Prize in Physics in 1932 “for the creation of quantum mechanics.”
While in Munich, Sommerfeld also mentored Wolfgang Pauli on his thesis on quantum theory, and Pauli also went on to win a Nobel Prize in Physics, in 1945, for his discovery of the eponymous Pauli exclusion principle (which stated that two or more identical fermions can not be in the same quantum state within a quantum system at the same time).
If all that wasn’t enough, he also mentored Hans Bethe while at the University of Munich; Bethe was awarded the Nobel Prize in Physics in 1967 for his theory of stellar nucleosynthesis (i.e., when chemical elements in stars change due to nuclear fusion).
While his own direct contributions to advancing the world of physics were prodigious, including his pioneering work in quantum theory, it was arguably for his teaching ability that Sommerfeld was most revered in his lifetime, with Albert Einstein once remarking, “What I especially admire about you is that you have, as it were, pounded out of the soil such a large number of young talents.”
Mathematician Morris Kline further stated of Sommerfeld that he “was at the forefront of the work in electromagnetic theory, relativity and quantum theory and he was the great systematizer and teacher who inspired many of the most creative physicists in the first thirty years of this century.”
Famed Jewish mathematician, physicist, and Nobel Prize winner Max Born (who was forced to flee Germany in 1933) went on about Sommerfeld’s talent for cultivating young minds who so often went on to great scientific achievements of their own:
Theoretical physics is a subject which attracts youngsters with a philosophical mind who speculate about the highest principles without sufficient foundations. It was just this type of beginner that he knew how to handle, leading them step by step to a realisation of their lack of actual knowledge and providing them with the skill necessary for fertile research. … He had the rare ability to have time to spare for his pupils, in spite of his duties and scientific work. … In this friendly and informal way of teaching a great part was played by invitations to join a skiing party on the ‘Sudelfeld’ two hours by rail from Munich. There he and his mechanic … were joint owners of a ski hut. In the evenings, when the simple meal was cooked, the dishes were washed, the weather and snow properly discussed, the talk invariably turned to mathematical physics, and this was the occasion for the receptive students to learn the master’s inner thoughts.
Going on about the man himself, Born stated,
Arnold Sommerfeld was one of the most distinguished representatives of the transition period between classical and modern theoretical physics. The work of his youth was still firmly anchored in the conceptions of the nineteenth century; but when in the first decennium of the century the flood of new discoveries, experimental and theoretical, broke the dams of tradition, he became a leader of the new movement, and in combining the two ways of thinking he exerted a powerful influence on the younger generation. This combination of a classical mind, to whom clarity of conception and mathematical rigour are essential, with the adventurous spirit of a pioneer, are the roots of his scientific success, while his exceptional gift of communicating his ideas by spoken and written word made him a great teacher.
Adding to his list of achievements, Sommerfeld eventually became chair of the Deutsche Physikalische Gesellschaft in 1918, a position previously held by Albert Einstein.
With the rise of the Nazi party in Germany, however, Sommerfeld was forced to watch many of his esteemed colleagues have to flee the country. As the aforementioned Morris Kline notes,
Sommerfeld’s life was saddened toward the end of his career by events in Germany. Anti-Semitism, always present in that country, became virulent in the Hitler period and Sommerfeld was obliged to witness the emigration of famous colleagues, including Einstein. All he could do was use the friendships he had built up during a one-year stay in the United States and a one-year round-the-world trip to help place the refugees. The loss of so many of its best men in this way together with World War II, destroyed the scientific strength of Germany, and Sommerfeld felt obliged to continue teaching until 1947, long after the usual retirement age of 65.
On that note, Sommerfeld had intended to retire much earlier, in 1936, putting forth one of his prized pupils, the aforementioned Nobel Prize winner Werner Heisenberg, as his hoped successor. However, as Heisenberg, like Sommerfeld, was considered by the Nazi party to be a Jewish sympathizer, ultimately the decidedly unaccomplished anti-Semite Wilhem Muller, with a lot of help from the Reich Education Ministry, was very controversial appointed to replace Sommerfeld as Professor of Theoretical Physics, despite Muller not even being a theoretical physicist. (Unsurprisingly, Muller was dismissed from the position in 1945 as a part of the denazification process that followed WWII.)
As for Sommerfeld’s once patriotic views, he wrote to Einstein shortly after Hitler took power,
I can assure you that the misuse of the word ‘national’ by our rulers has thoroughly broken me of the habit of national feelings that was so pronounced in my case. I would now be willing to see Germany disappear as a power and merge into a pacified Europe.
In any event, as for his own Nobel Prize aspirations, as alluded to, Sommerfeld’s contributions to theoretical physics were many and included groundbreaking work in quantum theory (including co-discovering the Sommerfeld-Wilson quantization rules in 1915), electromagnetism and hydrodynamics, and significantly advanced knowledge of X-ray wave theory, among other things.
Among his many awards were the Max-Planck Medal, the Lorentz Medal and the Oersted Medal, and he was also a member of the Royal Society, the U.S. National Academy of Sciences, the Indian Academy of Sciences and the Academy of Sciences of the USSR.
However, although he was nominated an astounding and record setting 84 times (the only other person close is Otto Stern, who was nominated 82 times before finally winning in 1943), Sommerfeld never won a Nobel Prize. His nominations for Physics were made in 1917, 1918, 1919 (twice), 1920, 1922 (four times), 1923 (twice), 1924, 1925 (six times), 1926 (three times), 1927 (three times), 1928 (three times), 1929 (nine times), 1930 (four times), 1931 (twice), 1932 (five times), 1933 (eight times), 1934 (six times), 1935, 1936 (twice), 1937 (eight times), 1940, 1948, 1949 (three times), 1950 (three times) and 1951 (four times).
Sommerfeld died on April 26, 1951 at the age of 82 as a result of a traffic accident that occurred while taking his grandchildren for a walk. At the time, he was quite hard of hearing and did not hear shouted warnings before he stepped in front of a moving truck. The distinguished scientist died two months later as a result of the injuries sustained in that incident.

As President Donald Trump has cryptically hinted at looming action on Syria, a new report says he may have nailed down eight potential locations to strike.
Citing an unnamed source, CNBC reported on April 12, 2018, that the US had selected eight possible targets in Syria, including two airfields, a research facility, and a chemical weapons facility.
Such a strike would amount to punitive action against Syria for what the US and its allies consider a blatant use of chemical weapons against Syrian civilians. But it would still carry the risk of sparking a war with Russia.
Ryan Bohl, a Middle East analyst at the geopolitical consulting firm Stratfor, told Business Insider that though Syria’s chemical weapons facilities lay under the umbrella of Russia’s air defenses, they were not actually close enough that a strike on the facilities would endanger Russian troops.
Russia has threatened to use its air defenses against US missile strikes, and Russian officials have threatened to counterattack if US missiles fly over Syria, potentially by attacking US Navy ships or submarines.
Dmitry Gorenburg, a senior research scientist at Harvard’s Davis Center for Russian and Eurasian Studies, told Business Insider that Russia had flown aircraft specializing in anti-submarine warfare to Syria. Russia has also moved its warships out of a naval base in Syria out of concern for their safety after Trump threatened strikes.
Russia operates out of airfields in Syria, but it’s unclear whether the US would target those. Syria has moved most of its jets to bases with Russian protection for fear of a strike, the CNBC report said.
The White House press secretary, Sarah Huckabee Sanders, indicated on April 11, 2018, that the US wasn’t afraid to target Russian assets in a strike on Syria. But a Russian newspaper reported that the US had been coordinating with Russia to avoid hitting its troops and would provide a list of targets before a strike to avoid escalating conflict between the world’s two largest nuclear powers.
Russia’s ambassador to the UN, Vassily Nebenzia, urged the US on April 12, 2018, to avoid military action, saying the “immediate priority is to avert the danger of war.”
Asked whether he was referring to a war between the US and Russia, Nebenzia said: “We cannot exclude any possibilities, unfortunately, because we saw messages that are coming from Washington — they were very bellicose. They know we are there. I wish there was dialect through the proper channels on this to avert any dangerous developments.”
He added: “The danger of escalation is higher than simply Syria because our military are there … So the situation is very dangerous.”

Several experts have told Business Insider that despite Russia’s tough talk, Russian President Vladimir Putin does not want a war with the US.
“Putin is not interested in a shooting war with the West,” Gorenburg said.
Gorenburg said that because a war could escalate into a nuclear conflict between the US and Russia, and because “the Russian conventional forces just aren’t as strong as the US forces,” such a fight “would not be a good outcome for Russia.
So far, Trump has played coy about the timing of a strike on Syria.
“We’re looking very, very seriously, very closely at that whole situation, and we’ll see what happens, folks,” he said April 12, 2018, adding that a strike could happen “fairly soon.”Meanwhile, France and the UK have been openly considering participating in a strike and sending forces to the region.
The US, with or without allies, has enough military presence across the Middle East to crush Russian forces in Syria — but a direct attack on Russian forces carries a risk of escalating a conflict into nuclear war.
Xi Jinping, China’s president, may have deliberately revealed how he plans to strike back at the US in the trade war by taking a trip to a magnet factory in eastern China on May 20, 2019.
Xi visited the JL MAG Rare-Earth factory in Ganzhou, where he learned about the “production process and operation” of the company, which specializes in magnetic rare-earth elements, “as well as the development of the rare-earth industry,” the state-run Xinhua news agency reported.
He was accompanied by Vice Premier Liu He, the country’s top economic adviser, who has been leading trade negotiations with his US counterparts, Trade Representative Robert Lighthizer and Treasury Secretary Steven Mnuchin.
Xi’s highly publicized attention on the country’s rare earths suggests he could use the products to cripple the US tech and military industries and make the Trump administration back down in the yearlong trade war.
Rare-earth materials consist of 17 elements on the periodic table that can be found in products critical to the US’s manufacturing, tech, and defense industries — from batteries and flame retardants to smartphones, electric cars, and fighter jets, according to Reuters and the Financial Times. They are used in tiny amounts but can be crucial to the manufacturing process.

“It’s signalling they know it’s not only important to US high-tech industries — electric vehicles, wind — but also defence. That’s the message they’re trying to get out,” Ryan Castilloux, the managing director of Adamas Intelligence, a rare-earths consultancy, told the Financial Times.
What rare earths mean to China and the US
China is the world’s largest supplier of rare-earth materials, accounting for 90% of global production, and the US relies on it for 80% of its rare-earth imports, the South China Morning Post and Bloomberg reported.
China’s state-affiliated Global Times tabloid described Xi’s Monday visit as the leader’s “huge support to the critical industry that has been widely viewed as a form of leverage for China in the trade war with the US, but one that also faces issues that need to be addressed.”

The Trump administration did not include Chinese imports of rare-earth materials in its latest lists of tariff targets, showing its reliance on China for them.
Shares of companies working with rare-earth elements skyrocketed after Xi’s visit.
China has weaponized its rare-earths exports in the past. In 2010, Beijing cut off the exports to Japan amid a maritime dispute that saw a Chinese boat captain captured by Japanese authorities.
The export ban was so powerful that Japan immediately released the captain in what The New York Times described at the time as “a concession that appeared to mark a humiliating retreat in a Pacific test of wills.”
In 2011, the House Committee on Foreign Affairs voiced concerns over China’s ability to use rare-earth exports in its foreign policy, in a hearing titled: “China’s monopoly on rare earths: Implications for US foreign and security policy.”
