This was the most powerful explosion ever . . . by a lot

Russia's Tsar Bomba is the single most physically powerful man-made explosion in human history. And it will probably remain that way forever.

On October 30, 1961, at 11:32 Moscow time, the 50 megaton behemoth detonated over the Mityushikha Bay nuclear testing range above the Arctic Circle. By comparison, the most powerful nuclear device ever detonated by the U.S. was the Castle Bravo hydrogen bomb over Bikini Atoll on March 1, 1954, which yielded the same energy as 15 megatons of TNT. The blast produced by the Tsar Bomba is the equivalent to about 1,350 - 1,570 times the combined energy of the atomic bombs that destroyed Hiroshima and Nagasaki, according to John D. Bankston in his book "Invisible Enemies of Atomic Veterans and How They Were Betrayed."

Or as the Discovery Channel video below puts it, "It contained the equivalent of 58 million tons of TNT or all the explosives used in World War II, multiplied by ten."

The explosion was so powerful that the modified Tupolev Tu-95 strategic bomber—Russia's version of the B-52—was almost knocked out of the sky. The mushroom cloud it produced was about 40 miles high, over seven times the height of Mount Everest.

The bomb destroyed all the buildings in a village 34 miles away from ground zero and broke windows in Norway and Finland. The explosion's heat caused third-degree burns on people 62 miles away. One test participant saw the flash through his dark goggles and felt the bomb's pulse 170 miles away. The bomb's shock wave was observed 430 miles from the ground zero, and its seismic activity was measurable even on its third passage around the Earth.

5 times Americans left to fight in foreign wars

In the past few years, dozens of veteran and civilian Americans left the comfort and safety of their homes to tackle what they saw as an unspeakable evil growing from the Middle East — the Islamic State. A new television documentary series from History followed those Americans as they fought with Kurdish fighters in Syria. The show pulls no punches in showing what combat looks like on the front lines of the fight against the world's most ruthless terrorists.

You can catch Hunting ISIS every Tuesday at 11pm on History but read on and learn about how and why Americans fought the good fight long before their country was ready.

"I heard the stories, I knew that ISIS was evil," says PJ, a Marine Corps vet who served in Iraq. "But you can never understand the brutality that they're capable of until you see it with your own eyes... Most people in America aren't able or willing to come over here," he says. "And for them, I will carry what weight I can."

This Microsoft training fast tracks veterans into sweet tech careers

Solaire Brown (formerly Sanderson) was a happy, gung-ho Marine sergeant deployed in Afghanistan when she realized her military career was about to change. She was tasked with finding the right fit for her post-military life – and she knew she wanted to be prepared.

Injuries sustained during mine-resistant vehicle training had led to surgeries and functional recovery and it became clear Brown would no longer be able to operate at the level she expected of herself as a Marine.

Like many of the 200,000 service members exiting the military each year, Brown knew her military training could make her a valuable asset as an employee, but she was unsure of how her skills might specifically translate to employment in the civilian world.

Enter Microsoft Software & Systems Academy (MSSA), a program Microsoft started in 2013 to provide transitioning service members and veterans with critical career skills required for today's growing technology industry.

Why splitting California into 3 made the November ballot

Tim Draper is known for having crazy ideas — and for funding them.

Now, the legendary Silicon Valley investor is making headway on a longtime and perhaps unrealistic effort to split California into three states: Northern California, California, and Southern California.

Draper's proposal to cut up the Golden State qualified on June 16, 2018, to appear on the ballot in November 2018's general election. It received more than 402,468 valid signatures, more than the number required by state law, thanks to an ambitious campaign called Cal 3 and financial backing from Draper, an early investor in Tesla, Skype, and Hotmail.

This band hires vets — especially when they go on tour

As veterans re-enter the civilian workforce, many struggle to make the transition. This is why opportunities (ahem — touring with famous heavy metal bands) for employment are so important. Five Finger Death Punch has made it a mission to offer such opportunities.

Why China's President warned Obama about 'immature leaders'

Days after Donald Trump won the 2016 US presidential election, Barack Obama left the country for his last trip abroad as president.

The trip took him to Greece, Germany, and finally Peru, where he attended the 2016 Asia-Pacific Economic Cooperation summit. Throughout the trip, anxious world leaders greeted Obama, inquiring about the man who would soon occupy the Oval Office.

That sentiment was on display in Lima, where "Obama was pulled aside by leader after leader and asked what to expect from Donald Trump," the former deputy national security adviser Ben Rhodes wrote in his memoir of his time in the White House, "The World as It Is."

Trump and Mattis go 'good cop, bad cop' on Putin

President Donald Trump and Defense Secretary James Mattis offered strikingly different perspectives on Russian President Vladimir Putin in the course of just a few hours on June 15, 2018.

Speaking with reporters outside of the White House, Trump blamed former President Barack Obama, not Putin, for the annexation of the Ukrainian peninsula of Crimea in 2014.

"President Obama lost Crimea because president Putin didn't respect President Obama, didn't respect our country and didn't respect Ukraine," Trump said.

5 things about the M16A4 that you complained about

The M16A4 was the standard service rifle for the Marine Corps until October, 2015, when it was decided that the M4 Carbine would replace them in infantry battalions. For whatever reason, civilians tend to think the M16A4 is awesome when, in reality, it's actually despised by a lot of Marines.

Now, the M16A4 is, by far, not the worst weapon, but it didn't exactly live up to the expectations laid out for it. They're accurate and the recoil is as soft as being hit in the shoulder with a peanut, so it certainly has its place. But when Marines spend a considerable amount of time in rainy or dusty environments, they'll find it's not the most reliable rifle.

Here are some of the major complaints Marines have about the weapon:
