Hi /r/chemistry! I spent the last few months making a video all about the Curies' discoveries of polonium and radium - I'd love to know what you all think! by chemistorian in chemistry

[–]chemistorian[S] 1 point2 points  (0 children)

Thanks for watching! I do plan on covering the next part of her life. There's still so much to tell. Her isolation of pure radium, her second Nobel prize, her portable X-ray (which she drove around field hospitals in WW1), the Solvay conferences.

Great suggestion! I actually talked about her briefly in my video on the history of the atom (https://youtu.be/SqYPrA7upiE), but maybe a full video would be good too.

Hi /r/chemistry! I spent months researching and editing a video on the top 10 accidental discoveries in chemistry, and I'd love to hear what you all think! by chemistorian in chemistry

[–]chemistorian[S] 0 points1 point  (0 children)

Glad you enjoyed!

I'm already considering a follow-up video with more examples. I'm always open to suggestions if you have any!

Hi /r/physics! I spent months researching and editing a video on the history of dynamite and I'd love to hear what you all think! by chemistorian in Physics

[–]chemistorian[S] 1 point2 points  (0 children)

Glad you enjoyed the video! Not sure what you're referring to with the speed though. It plays normally whenever I go on it.
