Is there really much value checking multiple solvers if you use the same pre-post which might introduce the same common errors, including user error, into all of them? I know it would be handy from time to time but validating solvers agains

It's a bit unclear who the target market is. Is it scientists? It doesn't seem to be for typical engineers who have a lot of very specific needs in FEA software. I can't see much aimed at them on the website. Examples of bi

The fact that you can use so many diverse tests as IQ tests and still get well correlated scores is itself a discovery. So is the fact that those scores correlate with various other life outcomes and that we can't find any lasting inte

They crawl it with a phone bot so they won't collect things that aren't provided to phone users. Old fashioned HTML+CSS works on phones. It might not be a good size but at least it's all there. I guess it doesn't matter

It's not quite that scary. They're removing content that the site operator explicitly made unavailable to mobile phones. Old pre-mobile sites will be fine. I would direct the "fuck that shit" to those websites that activ

On a bigger scale, Christians used to be anti gay for seemingly their whole history, then when others in the same western society decided gay is OK, they suddenly decided that Jesus was telling them to be tolerant all that time and all thos

There are so many things named with stupidly inconsistent capitalization that we should all stop caring and just capitalize the first letter like any other proper noun. I often have to google a product or company name to find out the correc

I think we know how to solve all education problems technically. It's just that the solutions are impractical. Sometimes personalized (expensive management) or require a smart and quick thinking teacher which doesn't scale well, o

The funny thing is the researchers always talk about search and rescue applications. They've been inventing search and rescue robots for decades. Flying ones, walking ones, wheeled ones, jumping ones, self-assembling ones, object detec

Then how do they make conventional replacement parts? Somebody must know the dimensions, tolerances, materials, etc.

How do we know they're travelling at exactly c? That's my concern. Last I heard, a couple of decades ago, physicists would occasionally measure a new maximum possible rest-mass for photons. It would be very tiny, of course, but th

How can it be objectively true when there isn't even an objective definition of white supremacy, let alone knowledge of who subscribes to that belief? But even then, growing on what time scale? It's surely been in decline over the

I'd say for most students, the vast majority of time they spend in school, they're not learning anything. The content of curriculums are usually quite short and can be crammed in a few weeks by a dedicated and intelligent enough s

The mainstream news media is actually pretty good at being technically factually correct, but it's so heavily biased that normal people can't see the truth behind the spin. What they take away from a story is the emotion, not the

It still doesn't sound physically distinct any more than distinguishing any continuous quantity as being zero or nonzero. If we measure something that looks like 0, we can't be sure if it's just below the sensitivity of our i

But is there any physical way to distinguish these fundamentally different situations? If not, then perhaps the fundamentalness of it is just an artifact of the formulation. I'm thinking of solar neutrinos which, for a while, we weren&

What direction is the earth accelerating in Australia? It's not deforming.

By arranging mass. We can also generate propagating gravity waves by accelerating mass.

by lopmotr 6y ago
I think treating gravity as an acceleration is too abstract for many high-school students. For all the on-the-Earth problems, you'd have to analyze them in an accelerating reference frame. That means Newton's laws and the equation

If you consider your body has extent in time, then when you move between two points in space, your body is a long worm connecting those two points. So your size in some way is related to the distance you travel in your life. But even withou

While I agree in principle, I don't think many humans are capable of what you want. Without a desperate need to work, most people don't seem to bother doing much even it that would give them great satisfaction. Just look at almost

I'm curious why they don't make 3D models from the original drawings. Maybe they're lost or kept by the manufacturers? By only measuring existing parts, they wouldn't know the tolerances or loads and would have to kind o

Energy density is only one factor. Cost per kWh is more important for people with plenty of land.

That's aluminium. Steel is magical because it has an infinite fatigue life for cyclic stress below the endurance limit and you can design things to operate in this region. Pressure vessels are also designed to leak before bursting, so

Maybe I'm not seeing the powerful features, but I don't understand why people are calling it impressive. It seems to be just moving existing mesh nodes in the normal direction which is an extremely simple operation to implement. T
