Dude worked with Rutherford and Thomson, | can we find anything on him? | holoduke wrote: | 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. | buescher wrote: | Another proponent of mechanical television! | martyvis wrote: | The style of writing is amazing.
