Over the years many molecules have been used to commit murder. For example, one main killed 5 of his children by using a charcoal burning grill. Another example is when a man, who later became a professor at the University of Manchester, attempted to murder his wife by using atropine. There are many more examples of when chemistry has been used, or attempted to be used in murder.

Dan, OK. I wold have liked to see one or two more examples. 5 stars. MW

I found the article, Redefining The Kilogram to be very interesting. One point that I found rather relevant to our class was when it talked about the prototype having lost 50 micrograms. While it might not seem like a lot, I can definitely understand how it would make a difference. I thought it was interesting how all other standards had a unvarying physical property of nature to use as a basis instead of a physical artifact, it makes sense that they are considering changing it for the kilogram. I don't really understand what Avogardo's constant is but it seems like it would be a good idea to have the kilogram based off of it since it would please chemists and link the mole to the kilogram.

Dan, Sounds good to me! Good thoughts on the standard being established. 5 stars. MW

I think method A seems to relate to our class at the time the most and found the sub-section "The photon-electron connection" to be very interesting. Hertz observed beams of light and, when shined on a given surface, their ability to cause electrons to be ejected. This would then ionize the elements that make up the surface I assume. I wonder if this is the method scientists use to make ions. I also found the section discussing infrared light sensors to be interesting as well though it seems like a much easier to trick sensor than the first and second methods. Since clear glass will block 8-12 micrometer IR light, wouldn't someone just have to carry a glass panel to trick the detector? Myth Busters actually did an episode on getting past motion detectors which I believe showed that if you covered yourself in mud it would also block the IR light that your body naturally emits and so you'd be able to get by that way too.

Dan, I've heard about that mythbusters episode and will have to look for it online. Good post 5/5. MW
