Today, I had a fun-filled day at SFU. First, I learned about ecology and biodiversity and the many different niches that exist in the forest around SFU. Then, we learned some tricks about odds in gambling in an irmac lab. We used a computer program to simulate the odds of tossing a coin, etc, and made graphs out of it.
Finally, (the coolest part of all), we saw some demonstrations of electricity, semiconductors, liquid nitrogen, superconducters, and levitations (yes, levitation). When a superconductor is cooled with liquid nitrogen, it generates around it a magnetic field, which could make a magnet levitate in the air. Then, we used the same properties of a superconductor to make an actual "maglev" train which hovered over metallic tracks! This is the best physics demonstration I have ever seen in my life.
