(disclaimer that I work in a climate group) > The only way to do anything is to sacrifice something. I think this narrative is not correct, or at least makes it seem like climate change will only get solved if we stop being consumerists.

A fun side note, the Western Boundary Time Series project is a neat bit of physics: https://www.aoml.noaa.gov/phod/wbts/ One can measure the rate of flow of seawater (about ~30Sv, or 30 million cubic meters per se

> and we're not at sub-millimeter precision yet ... out of curiosity, why not? Also, do you need MRI-guided or can one just use a much higher frequency ultrasound to see where it's targeting? Regardless, seems like a classic RL

Solid state microwave ovens (that avoid standing waves/dead zones) do exist, they are just very expensive. Dumping kWs of ultrasound into food would be a bit tricky.

You can make a scarce good cheap, just not for everyone in the market... hence the entire point of the discussion.

Actually woven, or fiber reinforced composite? Regardless, s-2 glass fiber is probably a better choice

They are usually reflective out of band, for unifacial (ito on semiconductor on a metallic backing), so ~40% of the radiation is heading back to space, vs 10-20% for a typical roof. However... that means they don't radiate well at nigh

Well, the land/ocean flux numbers for the "Yearly Absorption of Human-Induced Gross CO2 Emissions" have quite large error bars in the literature. CH4 numbers are also questionable.

by chris_va 3y ago
(I work in a climate group) These graphs really would benefit from error bars, especially the breakdowns into sector. I would not want a policy maker to rely on those numbers.

by chris_va 3y ago
There really isn't a huge advantage for 3 phase unless you are doing high-power DC rectification or trying to run a motor. The US grid is basically 3-phase everywhere, but it's neither needed nor cost-effective to run it into the

Well, that NASA page has the closest approach going into next week and a ~10% of impact, so... hopefully the big disclaimer at the top is relevant.

A moving magnetic field will move around any conductor, it doesn't have to be superconducting. A better video would be nice.

Anyone more knowledgeable know why they can't file for a single patient IND, assuming the vaccine is even acquirable?

While the pitchfork argument may be appealing, the actual article makes a convincing case that it's just combinatorial expansion: > As a result, the Transparency in Coverage rule requires insurance companies to do the math for patie

So, taken over by private equity in 2017... It'll continue to operate... I'm curious what fraction of the creditors are backed by Cornell Capital (PE owner), and if they just are using this to wipe out retirement plans/other

Sure... CO2 capture => Fischer-Tropsch => wax => fatty acid => food. The CO2 capture part is new, and presumably one would use solar now, but the rest was attempted during WW2. E-fuel plants do this for synthetic aviation fuel.

I actually ran a full character-level diff with move detection over the entire wikipedia edit history (few thousand machines) back in ~2008. The vast majority of content was created by a long tail of users, with a very small minority of use

If you buy a stock on NYSE, you don't actually hand money over to NYSE itself...

In this case, those folks lost all their money, so it seems like they actually did have pretty well aligned incentives... I think the more subtle distinction would be making short term risk adjusted incentive identical to long term risk adj

"passes losses to be bailed out through opaque means" isn't at all correct. Comparing SBF to to buying treasury bonds is somewhat laughable... let's focus on what actually happened instead.

I'm just curious, what do you think should happen here? Imagine you are hosting a demo for fun, and people do some nefarious (by your own estimation) things with it. So, rationally, you decide to not allow that sort of thing anymore. Y

How are we defining capitalism here? Because, you know, people are still getting paid for the work they are doing.
