  • Citing measurements made at the 1926 Iowa State Fair, they reported that the peak power over a few seconds has been measured to be as high as 14.88 hp (11.10 kW) and also observed that for sustained activity, a work rate of about 1 hp (0.75 kW) per horse is consistent with agricultural advice from both the 19th and 20th centuries […]

    Sounds to me like the 1 hp unit is fair, after all.






  • Are these decay rates specified for isolated atoms?

    I believe they would decay faster when bombarded by particles from fellow atoms, no? So we’d have to account for the mass, shape and density of the samples to get true rates. I don’t think that would change the rankings, but it might increase Simon’s troubles if the radon was frozen or otherwise really compressed, for example.
