       | That's a very good receiver for 1933. Most television of that era
       | was still rotating-disk systems. This receiver is intended to
       | receive signals meant for Baird rotating-disk receivers. 12.5
       | FPS, 30 lines is the rate they give, although there was no firm
       | standard at that point.

       | to require reiteration here, and our scepticism of the
       | possibilities of the mechanical methods of transmission and
       | reception have frequently been expressed."

       | "When I was working at the Cavendish Laboratory at Cambridge I
       | once get a bad attack of X-ray burn on the face, which was very
       | irritating and painful for a few days - for all the world like
       | extreme sunburn - but the tube I was using was not a cathode ray
       | tube, it was very much ' harder' and enormously more powerful.
       | After that, you may be sure that I took extra special care to
       | avoid any possibility of a recurrence of the same experience,
       | and, although I have worked with all kinds of cathode ray tubes,
       | I have never found it necessary to take the slightest precautions
       | against soft X-rays and I have never experienced the slightest
       | harm."

       | Ah, the good old days. Dude worked with Rutherford and Thomson,
       | can we find anything on him?

         | Don't you think that x-rays have potential long term cancer
         | effects? I worked with some medical devices in the past. Often
         | after work I used the device in my own body or random equipment
         | just for fun to see the inside. I didn't know anything about
         | side effects..I am still alive 20 years later and i think it
         | wasn't too bad. But still.
