My napkin math is that a bubble with a shadow the size of Brazil and made out of graphene weighing 0.77 mg per square meter would weigh about 25 million kg. Using multiple smaller bubbles could reduce this by at most a factor of four. At a

Seems like the key consideration is the mass of the bubbles. If they are light enough then this could be feasible.

The triviality argument seems to be an informal proof by contradiction. (1) Suppose there exists a program `conciousness.exe` whose computation is conscious. (2) A block of iron is not conscious. (3) There exists a (presumabl

Honestly, just using existing corn less wastefully in the US might solve the problem.

I'm kinda skeptical of the severity of this issue. Apparently Ukraine was expected to export 33.8 million tonnes of corn this year. The USDA says that the US produced 13,691,561,000 bushels of corn in 2019. If I converted the units cor

This would have an interesting potential to cut down on password sharing for subscription services like Netflix, Amazon prime, etc. I think it would be more annoying to call a friend to confirm an authentication on their phone than it is to

There appears to be satellite imagery of Russian columns passing through the Chernobyl Exclusion Zone, which would support this thesis. https://twitter.com/CSBiggers/status/1497000126719606790

The Russian forces seem to be trying to encircle or assault Kyiv. I think they've taken the nuclear plant because it is a defensible point along their shortest line of advance. They wouldn't want to move past it without controllin

A very interesting article as usual from this source. I particularly enjoyed learning of the marvelous social mechanisms which elevated Roman living standards without the technological advancement which created the modern world. It is fasci

The process of going from rocks to manufactured goods is fascinating, and probably part of the interest in Minecraft. Obligatory link to a video showing the home refinement of iron metal from minerals: https://www.youtube.com&#x2

You can use the ore to produce potent sources for calibration and such. As it is though, this seems like an overreaction. Radon detector / Alpha-beta radiation source. https://fusor.net/board/viewtopic.php?t=9166

This seems dumb exaggeration. I assume 'natural uranium' refers to ore which is not particularly radioactive nor dangerous. It certainly isn't explosive, you can buy it on ebay.

So many times making names for a DND campaign, I have regretted that regular thesauruses don't show archaic synonyms. This is perfect. I am totally going to use this.

It is refreshing to read a headline about an antibody test that conveys useful information about specificity and sensitivity rates. This really helps to inform about how useful a test could be for serological surveys. Well done Hacker News.
