…and it appears they are going backwards…. Synchronicity or serendipity?

Promethium derived from Prometheus, the Titan in Greek mythology who stole fire from Mount Olympus and brought it down to humans, to symbolize "both the daring and the possible misuse of mankind's intellect". A sample of the metal was made only in 1963. The known isotopes run from 128Pm to 166Pm, 39 in all; the most stable are 145Pm with a half-life of 17.7 years, 146Pm with a half-life of 5.53 years, and 147Pm (the common isotope) with a half-life of 2.6234 years. 143Pm and 144Pm also have lengthy if poorly-known lives on the order of a year, but all the others have half-lives that are less than six days, with the majority less than a few minutes. There are also 24 known meta states with the most stable being 148mPm at a half-life of 41.29 days. It reminds me of my own time at Los Alamos.

The element has not changed, but our number has. Eu is still relevant at 151. https://www.skool.com/goosify/you-want-to-see-clearly-in-all-colors?p=94575480 I understand we have a few more days. Maybe we will still break 150? It is not surprising. Congratulations to all who progressed. One lesson here for others considering the Blitz in Jan. Those that progressed in November will hit a similar deceleration limit too. The newer you are, the greater your room for improvement. I have the impression you are better off starting the blitz with at least 25 interested members in your community. I need about 20 more. 😬
