Matter is a lush tapestry, woven from a complex assortment of threads. Diverse subatomic particles weave together to fabricate the universe we inhabit. But a century ago, people believed that matter was so simple that it could be constructed with just two types of subatomic fibers electrons and protons. That vision of matter was a no-nonsense plaid instead of an ornate brocade.
Physicists of the 1920s thought they had a solid grasp on what made up matter. They knew that atoms contained electrons surrounding a positively charged nucleus. And they knew that each nucleus contained a number of protons, positively charged particles identified in 1919. Combinations of those two particles made up all of the matter in the universe, it was thought. That went for everything that ever was or might be, across the vast, unexplored cosmos and at home on Earth.

Don’t Fear the Tsar Bomba: Why This Nuclear Weapon Is Not That Scary
It is true this nuclear weapon was the largest bomb ever tested, but it was also incredibly impractical.
Key point: This bomb was very heavy and hard to transport. As a result, it actually did not make sense to use in a world with advanced air defenses and nuclear-armed missiles.
Maj. Andrei Durnovtsev, a Soviet air force pilot and commander of a Tu-95 Bear bomber, holds a dubious honor in the history of the Cold War.
Durnovtsev flew the aircraft that dropped the most powerful nuclear bomb ever. It had an explosive force of 50 megatons, or more than 3,000 times more powerful than the Hiroshima weapon.

Stevens Institute is going green
University to get 100 percent of electricity from renewable sources ×
The Gateway Academic Center received LEED Gold certification from the U.S. Green Building Council.
Starting in October, Stevens Institute of Technology will source 100 percent of its electricity from a local renewable energy source formalizing a three-year agreement with ENGIE North America, facilitated by energy consultant Gotham 360.
“The fact that it’s physical power, local to our grid, and 100 percent renewable energy – that’s pretty unusual for a university,” said Robert Maffia, vice president for facilities and campus operations at Stevens.
Many universities burn fossil fuels to power their campuses and offset that consumption by buying renewable energy certificates (RECs) to help support efforts to generate more clean energy.
