"General Relativity!"
"What is it, private?", replied the General.
Actually, GR (as those in the biz call it) is not a person at all, but the awesome theory of how gravity works. David Paganin (aka The General) fills us in on what it all means.
"I've invented a new number! Pie!" Mathematicians have been coming up with crazy stuff for years, but are they actually crazy? Films like A Beautiful Mind lead us to expect they are. We look at some famous (real) maths guys.
Quiz. Go figure.
There are some really cool critters in the ocean. Seahorses might be the coolest. Averaging about 15cm tall, they are a carnivorous fish and also monogomous.
They have a number of quirks, one being that the male is the bearer of the young. But a less-known fact is that they have no stomach. They suck in plankton with their snout and it passes straight through their digestive system. This means that they can't store the food and get energy out of it slowly over time, so they need to eat constantly.
You may know people like this, but I'll bet they're not as cute as seahorses are.
