The very first radiation symbol
@rooster you know, I have *never* thought about how the symbol is very clearly a sector cyclotron. HUH.
@rooster We can tell people it’s solid wifi in all directions.
@rooster so... has anyone measured exactly HOW radioactive it is? 😀

@rooster

Could you please indicate where this original is displayed? Thanks! Just curious!

@rooster Some half lives are so long it's challenging to guarantee signs will last. Cultural artifacts, and genetic engineering approaches, are also in use or under consideration. https://www.youtube.com/watch?v=amn3kn0XPLQ

@slowenough Just in case you’re not aware, this message reads from the outside like “Let me teach this lady brain something about half lives and signs” rather than “I’m engaging with a woman who has ‘Dr’ before her name and whose entire career is in nuclear physics.”

@rooster

@FinalGirl @rooster Well boo, it was intended as a fun (musical) bit in theme with the fun historical bit, so I guess I failed at tone here. :-/
@rooster ohh my fuck the symbol makes so much sense when realizing it was designed after seeing radiation in cloud chambers
