That’s very pure EDTA:
Nature Jobs has encouraged folks to spread the word of their failures, as well as their successes. So I made a CV of my failures. I’m probably forgetting a lot of failures, but I’m not really motivated to spend a lot of time trying to remember. Anyone else want to air their dirty laundry?
So why is gold valuable? NPR’s Planet Money has a fun podcast exploring the chemical reasons that humans value gold as a currency. Prof. Sanat Kumar goes through all the elements on the periodic table, and explains the reasons that each element couldn’t be a currency. For instance, lithium can be explosive when exposed to air, noble gases are really hard to keep in your pocket, silicon is too abundant, etc.
The podcast concludes that it was inevitable that humans would choose gold as currency. Cute.
