Re: 43S News

Here's a website that has an actual photo of the device. https://www.westland.net/ny64fair/map-docs/generalelectric.htm Thanks for sharing this link, nice read. Inside the pavilion was the first demonstration of controlled thermonuclear fusion to be witnessed by a large general audience. A magnetic...

Re: 43S News

The chamber after the "fusion" looked like before, didn't it? Impressive! :mrgreen: Worth a set of flashes ;) Btw that's one important difference to the bomb... maybe even the crucial one... 8-) Addendum: when we did our measurements for my master's degree end of the Seventies, we achieved some thou...

Re: 43S News

I remember seeing a demonstration of fusion in the General Electric pavilion at the '64-'65 Worlds Fair in Flushing, NY. We walked down a big spiral ramp and in the center, at the bottom was a big machine with a clear domed top. The fusion lasted much less than one second and there were a lot of fl...

Re: 43S News

Looking at the technology, it's a fission reactor basically - producing persistent radioactive waste for which mankind hasn't found a reasonable way to get rid of in 70 years of nuclear (fission) power so far. As long as this waste problem remains unsolved, I vote against such a technology leaving ...

Re: 43S News

And for the technology, I'm thinking about the molten salt reactor. Edit: Thorium-228, and it is about 2 years half-time.. For a start, I found three articles about molten salt reactors: https://de.wikipedia.org/wiki/Fl%C3%BCssigsalzreaktor and https://en.wikipedia.org/wiki/Molten_salt_reactor and ...

Re: 43S News

You wouldn't happend to have any influence in your industry, ... Which industry? If you know of any "physical" industry, please tell me. Personally, I've worked in various industries, from needles to pipelines, just to name both product size limits. BTW, most physicists moving to "industry" here we...

No secret - you find it in About the Author in each WP34S manual - experimental nuclear physics. 8-)
Cool! Fusion?
Nah - nuclear spectroscopy (but mainly real-time data acquisition and analysis).

Fusion was 40 years away when I studied and is now still (the so-called fusion constant).

Exactly :D Physicist's slang 8-)
Any particular physics slang? :D
That's solid state physics, but the slang goes through the whole departments of physics AFAIK. 8-)

Re: DM41X

There were a number of calculators designed for landscape layout, and they weren't HP's worst for sure. But redesigning a portrait calculator to become a landscape one is a far greater task than simply shuffling keys. Unless there are really qualified layouters or UI designers investing sufficient t...
