July 17 - proxying for Navsky, who's getting used to what he's lately started calling 'freedom' - freedom of an unbandaged, unfettered, unstapled Nobility!
Interestingly enough, just after one year with Rutherford at Manchester when he was offered further fellowship, Moseley declined.
Instead he moved to Oxford at the end of 1913 where he was given a laboratory but no support.
(Something like my position at the Wilmer Eye Institute in Baltimore in 2007-08).
But that is not to say that working under the Rutherford group was in vain.
Under Rutherford, it was inevitable that a scientist would work with radioactive elements as was the trend those days.
In 1912 at Manchester, Moseley attempted to pull back the beta particles (high energy electrons) from their radioactive source.
This sounded to me at first to be weird and quite silly.
But not to Moseley.
He was trying to prove Einstein's special theory of relativity experimentally by wanting to show that the mass increases with velocity.
He tried to hold back the beta particles by insulating the radium.
He hoped that insulation would make the residual uranium increasingly positive so that at the end the attractive force would prevent beta particles from leaving.
He had calculated that if the uranium could reach an electric potential of 1 million electron volts (MeV), the beta particles would be pulled back as they were emitted.
He was never able to produce this potential of 1 MeV to stop the beta particles.
However, he did manage to generate 150,000 volts or so on the radium, and thereby incidentally he created the first atomic battery!
An atomic battery is a devise that can generate electricity from the decay of an radioactive substance.
An atomic battery differs from a nuclear reactor in that it does not use a chain reaction.
These batteries are extremely expensive but have extremely long life and high energy density.
They are used as power sources for equipments that cannot be attended for long periods such as spacecrafts or closer home in cardiac pacemakers.
Anyway, this was not the primary reason for writing this bed-time story on Moseley.
We shall continue on Moseley hopefully tomorrow Sunday night assuming I do get time as I will be spending my entire day tomorrow on a cornea and oculoplasty CME.

Good night mon ami and my fellow cousin ape.
