10/7 Before Chemistry I did not even know mole day existed. Now, I have found out that mole day is a big deal. There’s even a theme song! Mole day reminds me of Pi day. Both days are based around a number that relates to a specific subject. For mole day, its based on Avogadro's number. Avogadro was an Italian scientist. He wrote a paper about his theory about 6.02 x 10^23. After he died, his colleague convinced scientists that Avogadro's number could solve many scientific problems. I found it interesting that he wasn't recognized until after his death. I guess it was because he was not a well known scientist.

Kelsey,

Sadly, many people are not appreciated until after their death. MW

11/2 I had no idea that there was such a thing as a dust explosion. I also did not know that explosions could happen in a sugar plant. I think it is tragic that a few people died during this explosion. Shouldn't these plants monitor how much dust is on the ground in case of an explosion? Well, anyway I think that stoichiometric relationships are very important to the rate of a reaction. They can cause harmless materials to become part of a dangerous reaction if the reactant is correct.

True enough! MW

12/4 I found this article the most interesting out of the ones we have read so far. I did not realize that two very reactive elements could form such a stable bond! I always thought that helium could cause you to pass out it because the gas did something funny to your brain. But, its actually because the lack of oxygen/excess of carbon dioxide. I think it’s very interesting that a balloon filled with sulfur hexafluoride would expand overtime. I’d like to see that!

Kelsey, Me too. I'm guessing it's a pretty slow process. MW

12/17 I had no idea motion detectors were that complex. I was also very interested to find out that humans give off infrared radiation. Cool! Reading about the photon-electron connection made me realize that what we are learning in class really applies to the outside world. After reading this article I am more interested in learning about other ways that physics relate to our lives. I will now think about photons and electrons way more often!

Kelsey, Mission accomplished! Good post. MW
