The Z3 was not a general purpose computer; it was a calculator that performed a predetermined sequence of operations that was written to its tape. It was remarkable for being all-b…

The claim that the Z3 computer was Turing-complete is not true. There is a paper arguing for it, but a detailed reading of it shows that this is an extremely far-fetched and somewh…

That's how this plane worked - the inflation pressure in flight was supplied by the motor. I don't think heating the air was desired, but some heat will inevitably end up in the ai…

No, you're not even close.

That doesn't say anything about Polonium being selectively taken up by the plant and used for growth. Just contamination on the sticky covering of the plants. Which doesn't make sm…

A quick search doesn't bring up any examples of radiophile organisms, in the sense of taking up radionuclides that are used for something. "Radiophile" bacteria exist, but that jus…

Can someone explain what we are talking about here? Something having to do with Musk's son's name?

I am not the best person to ask, since it's not my field. I heard this from the neuroscientists that I worked with. My understanding is that there are spiking and non-spiking neuro…

Ralph's main work was on neural impulses in the visual cortex, and on measurements of various potentials in the living brain. He published a memoir called "Another Day in the Monke…

I was lucky enough to do some programming work, very many years ago, in the 1990s, in the laboratory of Ralph Siegel ( https://en.wikipedia.org/wiki/Ralph_Siegel_(scientist) ), who…

I explained above what happens when the dimension grows - spheres and cones do indeed take up a smaller and smaller portion of their unit cube, eventually having negligible volume.…

Actually, you have that exactly right, and it's a very important fact in mathematics and statistics. A unit sphere takes up a smaller and smaller part of a unit cube as the dimensi…

Sure, have fun: "Workers of the Soviet Union! Let us consolidate ourselves even more around the Communist Party and the Soviet Government, mobilize our forces and our creative ener…

The closest thing to a universal approach would be a Kalman filter. It's usually where you start when you have noisy measurements coming in, and you need to maintain state such as …

This calculation amplifies any noise present in the values of the function, often to the point of the output being unusable. There are many methods that can be used to approximate …

Even if you're limited to uniform sampling, something as simple as the trapezoid rule will give you quadratic convergence instead of linear for the naive Sum(f(t_i) * delta). In ot…

Can't pass by without making a public service announcement about the average speed example: don't compute integrals using the calculus definition of Sum(f(x_i) * delta). Look up qu…

Wouldn't work, since 5 is not a member of the set of indescribable numbers. I am still not sure that the original example is good, since serious difficulties with the axiom of choi…

I don't know who applied it to LLMs, but it is/was the standard term used for an image processing model producing a detailed signal not justified by its inputs. For example, "face …

I don't know the details about the showing of that movie, but America's mass car ownership certainly came up in the comparisons of life in the USSR and in America. In one discussio…

It is actually. Norway has a large offshore oil and gas industry, and because of this it has a lot of companies that specialize in underwater work. When the Kursk submarine sank in…

These objects are much too faint to see much of anything with human eyes. We can see them in astrophotography because the exposures are hours long (or weeks even, sometimes), and b…

Agree with the other commenter, this definitely needs more details to describe the nature of the breakthrough. Sophisticated CAD in the browser is not a new thing. For example, Ons…

Great site, I've gotten into Go in a big way during the last year, and SL is still the best overall free resource after all these years.

Seeing how the actual Declaration of Independence promulgated by the actual would-be founders of Palestine states that "The State of Palestine shall be an Arab State and shall be a…
