“A boy and his atom” is officially the tiniest stop motion film.
IBM made this film by manipulating single carbon atoms on a copper surface. The size of this is unimaginable, as each frame is 45 X 25 nanometres and would take 1000 of these frames laid end on end to span the width of a hair.
The images were taken using a scanning tunnelling microscope which picks up images based on the concept of quantum tunnelling. The images are not of atom’s themselves as they are impossible to see, but is an interpreted image based on the current picked up by the microscope when a voltage difference is applied.

Astronauts onboard the International Space Station spend most of their time doing science, exercising and maintaining the station. But they still have time to shoot hoops and toss around a football.
From chess to soccer, there’s a zero-gravity spin to everything.
1. Baseball
Baseball: America’s favorite pastime. JAXA astronaut, Satoshi Furukawa shows us how microgravity makes it possible to be a one-man team. It would be a lot harder to hit home runs if the players could jump that high to catch the ball.
2. Chess
Yes, it’s a sport, and one time NASA astronaut Greg Chamitoff (right) played Earth on a Velcro chess board. An elementary school chess team would pick moves that everyone could vote for online. The winning move would be Earth’s play, and then Chamitoff would respond. About every two days, a move would be made. But who won the historic Earth vs. Space match? Earth! Chamitoff resigned after Earth turned its pawn into a queen, but it was game well played.
3. Soccer
NASA astronaut Steve Swanson put a new spin on soccer by juggling the ball upside down. However, he might not have considered himself upside down. On the space station, up and down are relative.
4. Gymnastics
NASA astronauts usually sign off their videos with a zero-gravity somersault (either forwards or backwards). But astronauts are also proficient in handstands, flips and twists. The predecessor to the International Space Station, the Skylab, had the best space for the moves. The current space station is a bit tight in comparison.
5. Basketball
Objects that aren’t heavy don’t move very well on the space station. They kind of just float. It’s like Earth, but exaggerated. For example, on Earth a beach ball wouldn’t go as far as a basketball. The same is true in space, which is why playing with a basketball in space is more fun than playing with a beach ball.
6. Golf
People talk about hitting golf balls off skyscrapers, but what about off the International Space Station? While golf isn’t a normal occurrence on the station, it’s been there. One golf company even sent an experiment to the station to find out how to make better golf clubs.
7. Football
Zero gravity doesn’t make everything easier. Astronauts need to relearn how to throw things because their brains need to relearn how to interpret sensory information. A bowling ball on the space station no longer feels as heavy as a bowling ball on Earth. When astronauts first throw things on the space station, everything keeps going too high. That would put a wrench in your spiral for a couple of months. But once you adjust, the perfect spiral will just keep spiraling!

The only clowns I acknowledge
A question that sometimes drives me hazy: am I or are the others crazy?
Albert Einstein
Burr is every bit as smart as Hamilton, and every bit as gifted, and he comes from the same amount of loss as Hamilton. But because of the way they are wired, Burr hangs back where Hamilton charges forward. I feel like I have been Burr in my life as many times as I have been Hamilton. I think we’ve all had moments where we’ve seen friends and colleagues zoom past us, either to success, or to marriage, or to homeownership, while we lingered where we were—broke, single, jobless. And you tell yourself, ‘Wait for it.’ —Lin-Manuel Miranda
