Absolutely. The public sales pitch did not match the reality. This is what I meant with the "Claim to be Ṕython to get VC money" point. To first order, today every programmer starts out as a Python programmer. Python is _the_ teac

I think it was pretty clear immediately that running python code was a far away goal. There was a lot more talk about lifetimes and ownership semantics than details about Python interop. Mojo is more like: Can we take the learnings of Swift

So nVidia has a huge software lead because of open source developers like you? Or because people employed by nVidia write closed source high performance drivers and kernels? Or because the people employed by Meta and Google that wrote Torch

It really depends on why you are having a philosophical discussion. If you are talking among friends, or just because you want to throw interesting ideas around, sure! Be free, have fun. I come from a physics background. We used to (and sti

I think this is a valid point. But to some degree both can be true. I often felt when reading some of these type of texts: Wait a second, there is a wealth of thinking on these topics out there; You are not at all situating all your elabora

Wikipedia would beg to differ: https://en.wikipedia.org/wiki/Orders_of_magnitude_(mass) The table at right is based on the kilogram (kg), the base unit of mass in the International System of Units (SI). The kilogram i

Russia decided to invade Ukraine. Russia decided to not fill EU gas storage to usual levels ahead of the invasion. Russia decided to not fulfill its contractual obligations in retaliation to the sanctions imposed by the EU. Objective realit

I agree with the argument, but... > [Would we allow a situation where] a foreign power could force them anytime to cut Europe’s power? We did just that with Russian gas imports. It took a massive effort to transition of these imports af

What an uncharitable reply. Not op, but you seem to miss the basic point of the article, I.e. you fail at your own criterion of making understanding your goal. As someone not in this space I found the argument succinct and easy to follow. Q

It's standard terminology. The point is that the threshold is different depending on whether you are coming from above or below. See here: https://en.m.wikipedia.org/wiki/Hysteresis#Rate-independent

Key sentence from the abstract: "The atmosphere’s fast mixing time scales were thought to inhibit the necessary memory effect for such multistability." In other words, this is an important but fairly technical result.

10 LB = LB' 0Q 0A 0A' The proof says iterate on A, so that obviously creates a lower dimensional rotation Q that will act on the full space as above. Absolutely mention this in lecture notes/during the lecture.

That's an absolutely obvious step though? As in, detailed lecture notes should maybe elaborate with a sentence, but in a lecture I would not put this on the slides but mention the core point and expect students at this level (who shoul

I think "the big bang happened everywhere" is more correct than your take. The big bang dlrefers to the early period of a spacetime with an initial moment. At that initial moment the distance between all points is zero. But there

If this was just the effect you mention you would not expect the base model to surpass the RL model though. Plus their k are much smaller than that. I think it's a very interesting and meaningful study.

I don't know who the target audience is supposed to be, but who would be the type of person who tries to implement performance critical numerical codes but doesn't know the implications of Taylor expanding the sine function?

An advertisement ban is also an interesting idea from the theory of free markets perspective. Consumer needs are met by the most efficient producers, products compete for consumers on the market. That makes a ton of sense. But ad spending i

Seriously, that's good to hear. I really often encounter arguments that seem heavily ideology driven. Do you have some sources for operational requirements not making things safer? And as far as I know there are plenty of fusion concep

What silly batteries example? If seasonal storage is solvable, solar + wind is not unreliable. And no, I don't have an anti nuclear agenda. But I know the energy system models and the results, and just how difficult integrating nuclear

PV is not heavily subsidized compared to other energy carriers, and the learning rate has been extremely consistent for a long time. LCOE takes some of the system costs into account, but it's of course true. And your second sentence is

You seem to think this contradicts my statement somehow? Obviously you want a tech mix, and obviously anyone working in the field is taking the dunkelflaute or other extreme events very seriously. That's where storage comes in, and tha

All I see is people with an aversion to solar and wind, that champion nuclear for purely ideological reasons. The aversion seems to be mostly driven by the fact that solar and wind were first championed by eco hippies, and some people seem

by Certhas 2y ago
What do you base all these claims on? Plenty of papers show Solar + wind + storage is viable practically everywhere. Also there is a ton of research on planning energy systems and what technology mixes make sense. This stuff has to be econo

For the EmDrive it also was that the claimed theoretical mechanism was mathematically impossible, because it was based on equations that (like all known equations and everything ever observed) satisfy the conservation laws. That's a go

Of course there are always reasons. But as long as the costs of recycling are not borne by businesses doing the packaging, the business will always go with the 1 cent cheaper option, even if it makes recycling 100 times harder.

Are you asking about the real world? Then the answer is that you can not perfectly craft the dome and what happens depends on the imperfections. Are you asking about a fictional universe governed by the Newton equations and nothing else? Th
