Paper.li

So you guys remember Ötzi the Iceman? In case you don't know who that is, I'll tell you in a nutshell. A few years ago, 2 hikers stumbled upon a dead body in the Alps in Ötzi inbetween Astria and Italy and they called in about it. Turns out, this body was mummified and had been there for about 5,300 years and was probably killed because of an arrow wound in the back of his shoulder.
Apparently, scientists have found his genome which will let them find out what color his skin and eyes were, how healthy he was, what race he was, and stuff like that. After using his genome, they discovered that he had brown hair, was lactose intolerant, had type O blood, and that he probably had cardiovascular disease and Lyme disease. His genetic make-up was from Sardina in the Mediterranean Islands. Scientists believe that his parents immigrated from Sardina to Italy for trade. I'm not the only one that thinks this is interesting right? It gets me wondering, what was is life like? Was he married? Did he have kids? Who shot him? And what was his real name? It's really interesting! Questions? Go to:

WIPP

WIPP is a cavern underground in Carlsbad, New Mexico that is used for the storage of nuclear waste. 10, 284 on average are made each year and 12,363,183 miles are travelled. A type of waste being transported is transuranic waste. Transuranic waste is waste that is usually contaminated with plutonium and uranium, which makes it VERY dangerous because plutonium and uranium are nuclear. It needs to be stored because of the radiation it gives off. WIPP is the site of choice because it's certified by the EPA (Enviromental Protection Agency) for storing the waste safely and for a long period of time. Personally, I think it's a bad idea to be storing the waste by burying it because the ground is always moving and if it moves just the right way, the maste will move and break. Also, our future generations will have to deal with what we should have dealt with, which is what we should figure out how to do so we don't just dump it on them. Any questions?

You Learn New Things Everyday

What I learned by reading everyone's blogs in Mrs. Engelbrecht's class is that if the world suddenly stopped, the water in the ocean, air, and man-made objects would probably keep going the same rate the Earth was going at before, (1,000 miles per hour) basically destroying our whole planet as we know it. I'd never really thought about that before because I guess it's just not something you think about. Also, that the metric system is more accurate than the imperial system and it'd be MUCH easier for everyone to use the same system rather than different ones.
I also learned that I'm not the only one that thought I knew everything about the Big Bang before this class. I thought I had the basic idea and that's all there is to it, but I really had no idea! There's so much more to it!

Big Bang

The evidence discussed in class supports the cosmological model because of the radiation and the fact that the galaxies are moving farther away and the ones farthest away are going faster than those that are closer. This is because the universe is expanding. The radiation is the aftermath of the Big Bang. Some questions the video brings up is why didn't the beginning of the universe mess up in any way? Sometimes things get messed up like a tree will grow funny, or a person is born with a disorder, but why didn't the universe mess up at all? Scientists should definitely be asking this question. I think new pursuits ARE possible because there is still so much that we don't know about our universe.
