I came across this as I was doing some random google searches, and found this quite neat. I can’t verify if the tortoise actually belonged to Darwin, but I couldn’t help but imagine the stories that the tortoise could tell. If the picture is true, then that would have been pretty awesome to have been met both Steve Irwin and Charles Darwin!
I saw this article and found it pretty awesome. I myself wouldn’t mind trying some insects! However, when I read this article the first thing that popped into my mind was if the insects were exposed to any pesticides. It reminded me of our DDT discussion where animals were dying when they ate insects that were exposed to DDT. What do you guys think? Would you eat a grasshopper or a meal worm?
Pesticides have been know to be endocrine blockers, but new British studies reveal that pesticides also block male hormones. Pesticides are screened to determine if they block testosterone or other androgens. However, only a few chemicals get screened by the EPA every year leaving hundreds of other chemicals dissolved into our food and water.
Someone in class mentioned how nuclear technology and radiation where used in the medical field, and I wanted to know more about it. I knew radiation was used, but radioisotopes are also used in the medical field. Radioisotopes allow doctors to detect tumors or fractures, measure blood flow, or determine thyroid and pulmonary functions in patients. Not only are radioisotopes used, but idione-131, a fission product, is used in diagnostics test for certain thyroid disorders.
So after skimming through The Giant’s Shoulders #72 I found nothing particularly interesting, however, I did find something sort of interesting in the 35th one.
Near the very start of the class we discussed how, in the past, scientific debate consisted mostly of ridicule, and this site has an example of this; an entire book ridiculing Athanasius Kircher and other predecessors of Newton.
I wanted to spend a day on 20th-century chemist Percy Julian, but ran out of time. Here’s a link to the interactive Chemical Heritage Foundation site about Julian’s life. Within the site, the CHF also links the very good NOVA video about Julian.
Greg Miller wrote an article for Wired’s website entitled, “Vintage Pesticide Paraphernalia From the Glory Days of DDT.” The article draws on the collections of the Chemical Heritage Foundation and ties nicely to our recent discussions of Silent Spring. Objects like those shown in the article help historians with an extended set of questions about an historical episode as compared to what we can pull out of books and articles alone.
