There are many towns in the U.S. that are named after elements. For example, Barium Springs North Carolina. This town was discovered in 1775 to have many mineral springs, a lot of them containing barium. It was initially known as Poison Springs because cows refused to drink out of it. It was renamed Barium Springs for the sake of attraction and the name stuck. Other towns across the U.S. have element names for similar reasons.

Nick, A little sketchy but OK. I imagine the barium was poisonous to the cows. It doesn't take much to deliver a lethal dose! 5 stars.

Redefining the kilogram I thought that the article itself was very fascinating. I thought it was interesting to hear that the kilogram was the last remaining base unit to still be defined by a physical artifact. All of the other basic units of the SI are based on some flexibility of nature's effects. I thought it was incredible to think that the tiniest fraction of a percentage of a gram could drastically throw off the standard kilogram. All in all I think that the standard kilogram is an important part of standard measurement today.

Nick, No doubt that the lost of mass has caused a lot of hubbub! Good thoughts 5 stars! MW

There were many interesting topics in this article, I thought that the most interesting thing about this was that there were devices that could listen to the infrared radiation, or warmth, coming off the body. Another thing that I learned is that a high-energy beam of light doesn't always produce a significant reaction from the electrons. The last interesting thing that I learned is that elevators and garage doors use infrared light sources to detect whether something is in the way or not, and that why they never close on anything in the way.

Nick, That is a very good feature of garage door opener/closers! Good post! 5 stars. MW
