Re: When did you become conscious of your heritage?
I became conscious of my heritage when I first started to study history in high school. As I gained knowledge of world events and their effect on peoples, I naturally connected to that which my ancestors may have been involved with. As well as how these events extended to other peoples. It didn't take long before I realized we all make up a world community and that borders and labels have led to prideful conflict and misunderstandings throughout history.
As I matured I was able to travel to the lands of my forefathers and absolutely fell in love with one of those destinations. I was also glad to find that people around the world are not so different from each other when we get face-to-face.
In recent time, I married an individual from another continent and the opposite hemisphere. It is amazing to us how similar we are at the core of being, even though we our recent living histories are quite diverse from each other. The important things are we laugh, love, listen to and learn from each other. Understanding and choosing early on in our lives made it possible to see people for who they are and continually learning what that is, not who we "think" or convince ourselves "know" they are.
Here's the science of black holes, from supermassive monsters to ones the size of ping-pong balls.
- There's more than one way to make a black hole, says NASA's Michelle Thaller. They're not always formed from dead stars. For example, there are teeny tiny black holes all around us, the result of high-energy cosmic rays slamming into our atmosphere with enough force to cram matter together so densely that no light can escape.
- CERN is trying to create artificial black holes right now, but don't worry, it's not dangerous. Scientists there are attempting to smash two particles together with such intensity that it creates a black hole that would live for just a millionth of a second.
- Thaller uses a brilliant analogy involving a rubber sheet, a marble, and an elephant to explain why different black holes have varying densities. Watch and learn!
- Bonus fact: If the Earth became a black hole, it would be crushed to the size of a ping-pong ball.
Military recruits are supposed to be assessed to see whether they're fit for service. What happens when they're not?
- During the Vietnam War, Robert McNamara began a program called Project 100,000.
- The program brought over 300,000 men to Vietnam who failed to meet minimum criteria for military service, both physically and mentally.
- Project 100,000 recruits were killed in disproportionate numbers and fared worse after their military service than their civilian peers, making the program one of the biggest—and possibly cruelest—mistakes of the Vietnam War.
In a breakthrough for nuclear fusion research, scientists at China's Experimental Advanced Superconducting Tokamak (EAST) reactor have produced temperatures necessary for nuclear fusion on Earth.
- The EAST reactor was able to heat hydrogen to temperatures exceeding 100 million degrees Celsius.
- Nuclear fusion could someday provide the planet with a virtually limitless supply of clean energy.
- Still, scientists have many other obstacles to pass before fusion technology becomes a viable energy source.
