Endrael AstronomyGirl magicalq91 i love science especially when u get to blow up things... twisted blaugh lol indeed! I love high school chemistry demonstrations. My teachers were nice enough to show us some cool exploding ones. ^_^ I loved those demonstrations! My chemistry teacher in high school managed to get hold of some sodium so he could demonstrate the reactivity of valence electrons (which I know isn't the right term, but I can't for the life of me remember what is whee ). He commandeered an old bucket and filled it with water, then dropped a tiny little piece of the sodium in. No more bucket. rofl
lol I actually got to do an experiment like that. Only less sodium, so it burned, but no explosion. Then we got to use some potassium... that was even crazier! 0_o they gave us such small amounts though, that nothing would blow up. blaugh |

What I love most at science, is not the demonstrations or experiments. I am (or am trying to become actually) a mathematician, so in "my" "science" you just start with nothing and finish with a result.
So, to continue, what I really like about science in general, math more exactly, is that you can make a theory, calculate things, find connections between things already known, and so on and so on, and then finish with a new result, that, most of the time can be used for new theories and (in case of math) be used for other sciences, informatics or economy.
This year for example, in the lessons about Markov Chains, we see very theoretical things, but they are used almost everywhere in nature. For who is interessed, we are now talking about martingales. Martingale theory is sometimes described as "fair bet": averagely you win the same amount as your stakes were.
Example of a very easy martingale: you have 1 gold as stake: throw a coin: one side up, you get 2 gold, other side up you get 0 gold, averagely you get 1 gold, exact your stake again.
But also Brownian motion, very important in physics, is a martigale.

ah math... so useful to physics and astronomy, but so annoying when I don't understand it and it doesn't work. Math and me is a love/hate relationship. blaugh |
