Bosnia War Stats and Numbers

Fifteen years ago in Bosnia, an ethnic group called the Serbs killed a
anyone that defied them. About 250,000 people died, whether it be the Bosnian-Muslims, Croats, Serbs or NATO troops. The conflict was that Yugoslavia broke apart and the Serbs wanted it to stay together. Bosnia, one of the new countries that were formed, is 37% Serb, 14% Croat, and 48% Bosniak, or Bosnian-Muslim, totaling the population at 4,377,053 in 1991 at the start of the war. The new size of independent Bosnia and Herzegovina is 19,767 square miles. The independent Croatia is 21,851 square miles and the population is 4,437,460 as of 2001. The new Serbia is 34,116 square miles with a population of 7,334,935 in 2000. These numbers are significantly smaller than former Yugoslavia and shows that math truly is involved in the world.

Jellyfish: Cnidarians(class response)


In class, we learned about cnidarians. I was fascinated by the interesting cnidarian known as the jellyfish. Now, I've seen Spongebob and I know that jellyfish sting. Yet I thought it was cool to find out more about them. One particular aspect that is cool is their reproductive cycle. A male jellyfish releases sperm and the sperm grows into a polyp on a rock. Then, parts of the polyp break off and swim away from relatively stationary polyp. Another interesting fact is that when plant fertilizer gets into water, it can mutate the jellyfish into much larger jellyfish. There are some jellyfish that can glow, just like fireflies. Overall, I think that jellyfish are pretty interesting for such a simple life form.
