A link to the preprint. I'll do the actual math on how many transitions/second it works out to later and edit.
I've had an eye on this for like a decade, so I'm hyped.
Edit:
So, because of the structure of the crystal the atoms are in, it actually has 5 resonances. These were expected, although a couple other weak ones showed up as well. They give a what I understand to be a projected undisturbed value of 2,020,407,384,335.(2) KHz.
Then a possible redefinition of the second could be "The time taken for 2,020,407,384,335,200 peaks of the radiation produced by the first nuclear isomerism of an unperturbed ^229^Th nucleus to pass a fixed point in space."
Avoiding the famous things...
Tracking mud into someone's house. The most striking cultural difference is literally just taking your shoes off as a guest.
Alligators, tropical diseases, hurricanes for the most part.
Flag-worship. Which is ironic because tomorrow is Canada Day, but really the US is on a whole other level.
Government deadlock.
Pennies.
Embargoing Cuba.
