  1. This isn't a comment so much as a question ,but I've heard it said that Xylitol used to appear as a liquid state at room temperature then somehow morphed and no longer appeared as mentioned anywhere in the world above and if so where can I find confirmation of same

  2. I'm almost surprised that photographic chemistry wasn't included, for the first time in history it allowed people to accurately see things they may have never otherwise had the opportunity to see. This lead to advancements in the fields of education and study of other cultures and for the first time ever provided some sense of cohesiveness between all peoples.

  3. There's an alternate reality where they got it all mixed up and planes showered the battlefield with military grade fertilizer while farmers bombed the crap out of their crops.

  4. Well it is chemical reaction, but it is something that is made by microbes, and I don't think it's still possible to be done without the use of living things that makes it biology not chemistry.

  5. Can someone please explain to me how bronze is a chemical reaction and not the simple mixing of two chemicals, which I should explain is not a chemical reaction?

  6. DNA sequencing will change everything but for now Sulfuric acid and Penicillin would be 7 and 8. In another 100 years we will be effectively a different species probably disease free, immortal and wired directly into a complete internet. Or if we don't take charge it might just be the Terminator without any good guys.

  7. Anybody else try to confidently convince a middle school teacher you were "smart" by telling them " Guess what? I know what 'e' equals! It's 'Mc squared'!".
    Where I got this from was literally just a piece of colorful cardboard banner similar to the 'abc' ones in all classrooms, just with odd math related stuff. Thankfully, the teacher I tried to impress was a good one. I recall them giving a confused chuckle at my confidence, but they actually taught me about what it meant to the extent that they could. We hadn't even been taught proper exponents or anything about mass/ momentum, I probably didn't have a clue it had anything to do with "speed" until explained. The local schools probably didn't learn more about it until high-school, making me extra grateful for that teacher, we need more like them! ♡

  8. You mentioned certain reactions that have always puzzled me. How did the Bronze Age (mixing of precise ratios of different metals) precede the Iron Age (just dig it up as is and hammer it into shape)? How did ancient humans use fermentation involving microscopic organisms that couldn’t be discovered for many thousands of years?

    You also let Haber off the hook for another contribution to society – genocide.
