Huh ?

"Both the electron and the proton rotates around their mutual centre of mass. During each revolution a negative and a positive charge circles around the centre-of-mass." As I see it, due to the proton being significantly more massive than the electron, the latter moves further from centre of mass, c...

Scientists image Rayleigh-Taylor Instability

http://www.physorg.com/news/2010-11-scientists-image-sea-monster-nuclear.html quote: (PhysOrg.com) -- A new X-ray imaging capability has taken pictures of a critical instability at the heart of Sandia's huge Z accelerator. The effort may help remove a major impediment in the worldwide, multidecade, ...

Pushing the boundaries...

Looks like a small portion of the material has gone superconductive. Pinning down the responsible phase and making it reproducibly will *not* be easy. Then there's the issues about forming into usable shapes and its tolerance of magnetic fields, not to mention temperature cycling... Whatever, this l...

Nice one !!

I'd recommend a back-up magnetometer with a wider range, though. 50~~100 % head-room will let you monitor 'excursions' and transients without ambiguity...

Right...

I've been following this thread from time to time, wondering if there was any validity to BLP's notion of a 'lower quantum state' {my words} for hydrogen. As I understand it, common or garden hydrogen is 'collapsed' using a proprietary BLP catalyst, issuing lots of energy. The 'collapsed' hydrogen b...

Hovercraft & Ekranoplan...

Rather than resurrect a thread from July, here's a thought... The US LCAC and UK's SRN4 hover ferry (Rtd) would seem a fair match for a polywell's power, size and weight. Each vehicle could handle large, heavy loads ( Battle Tank, several dozen cars), each required thirsty engines, each could be con...

Not neutron shielding...

Uh, I don't think the deposit thickness would have much impact on neutron flux, but it might provide a self-healing 'front surface' for the wall etc.

Like halogen lamps' halogen trace 'heals' hot-spots on the filament and removes spatter on the glass ??

( Within limits, of course, of course' ;-)

'Feeling the quarks' ??

I'm no physicist, but I must wonder if the pion is 'feeling' the charge separation in the proton's quarks...

FWIW, being 4% off in something so singular leads you to wonder what other surprises are lurking in the next decimal place of other atomic factors.

Scary...

Much as it would prove a point, IMHO, you really, really do NOT want the very first WB break-even to be 'explosive'. Okay, like early steam-boilers, some prototype WBs are likely to disassemble uncontrollably, but the basic concept is as far from nuclear fission and its weapon potential as you can g...
