At posting, I didn't have time to provide more references. You'll see I've given three more references below. Sources include Acta Physiologica, SPIE, and Neuroscience Letters. They discuss different effects of illumination c

Yes. It's the blue component (large with high color temperature lights) that is thought to most strongly affect human melatonin secretion and sleep. Here's one of many studies that indicate this: http://www.ncbi.nlm.nih

If Palantir is a CA business entity (I didn't check, maybe it's a DE corp), its noncompete should be per se invalid (= automatically void) in CA. There are only a few circumstances in which noncompetition agreements are valid in C

Inequality within arbitrary borders is important because economic environments, and therefore effects on individuals, are still defined by those arbitrary borders. AFAIK, it matters very little to my daily life or even to my two decade outl

On your first point: Inequality among nations is in decline, as you note. Inequality among individuals within nations, however, is on the rise. [1] I think this is as important as inequality among nations. [1] https://en.wikipedi

I didn't downvote you, but I do disagree with your view. A straightforward way to keep someone around after their four-year vesting clock expires is to grant them new shares on a new vesting schedule. Their initial grant was part of co

What selimthegrim said... And sorry, I see I wasn't clear about the precision delivery aspect. While newer members of the nuclear club may not have the greatest in precision delivery, that capability is almost completely a matter of el

I agree with your "other hand". I think the changes you cited (less damage due to high precision use of low yield weapons) make it on balance more likely they'll be used. The real barrier to nuke use is gaining entry to the c

The post minimizes the utility of a thorium reactor for making fission weapons. Neutron irradiation of the most abundant isotope of thorium (Th232) produces U233. The US, the USSR and India have successfully tested U233 in fission weapons.

Thank you for the link. I think the numbers quoted don't indicate a collapse in the wealth gap around 2008. The WSJ article includes this observation: "The world is still staggeringly unequal, with the tiny sliver of those with $5

I take the last quoted sentence to mean that the minimum wage "... would have reached $21.72...", not that it did reach that. Clearly, it didn't. The author was illustrating the overall decline in purchasing power of the i

On your last point: from a historical chart [1] of U.S. net household wealth (in a 2014 Economist article), it seems the wealth gap didn't collapse or even moderate its increase in 2008. Indeed, it's reached the same territory whi

I'm trying to optimize growth rate and quality as functions of plasma power density, deposition gas composition, pressure and substrate temperature. I think there's a lot of process improvement yet to be found. In the biz environm

Mine is mainly for research on plasma chemistry, so it's not set up for maximum deposition rate, which is an important parameter for commercial viability. I've made a 3.8 ct. unpolished stone in a 4 day run. If I were to do the la

The lab processes introduce color and flaws only if they're wanted. The old way of making diamonds, growing them in metallic solvents at pressures over 50K atmospheres (where diamond is the thermodynamically stable form of carbon) prod

DeBeers isn't buying out the labs. They're suing the labs for patent infringement [1]. The technology barrier to entry is low. If you have the tech chops and can spend $30K, you can do a DIY microwave plasma system and grow your o

This is pretty much the story of Diamond Foundry [1], a Bay area synthetic diamond company funded at ~ $100M to date [2]. Their marketing emphasizes the attributes you list in your last sentence. [1] https://www.diamondfoundry.c

OP said "...in parallel with filing of a patent application you can just publish it...". I think he means that upon filing the patent application, one publishes what one has filed to mitigate the return to the government from clas

Exactly right. Maybe there's a rare edge case that calls for illegal activity. If so, and if law enforcement does it, they need to explain their actions so we can determine whether they were right and should be excused or wrong, and sh

I'm curious - If I fly a GPS-dependent drone above 50 feet within the jamming footprint, do you think it would degrade or fail? If I were near the area, I might try the experiment.

This is inert gas asphyxiation [1]. CO2 buildup is what drives the panicked "I can't breathe" response. If there's no CO2 buildup and no oxygen, it's a rapid and apparently peaceful lights out. [1] https:/&#x

This only applies to impurities that don't dissolve in, or alloy with gold. For example, silver and copper cannot be removed from gold simply by melting because they form solution alloys that don't segregate in the molten state. S

NASA did just that. They flew Cassini through the geyser plumes at Enceladus to sample the presumed ocean beneath the ice on that world. At least twice. Once at an altitude of 30 miles.[1][2] [1] http://www.nasa.gov/multime
