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-binary in an era when differential gears and cams were very c

by yaakov34 2y ago
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 somewhat disingenuous stretch. (The disingenuous part is because a

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 air as it is compressed.

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 smoking tobacco good in any way, shape or form whats

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 just means they are highly resistant to ionizing

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 neurons in most nervous systems, including human, but most o

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 Monkey's Brain". I believe he had potential m

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 among other things worked on this type

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. This is important in the context of high-dimensional statis

by yaakov34 3y ago
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 dimension grows (and a unit cone is similar). In other words,

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 value and derivative. Since the original question was a

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 derivatives, depending on the problem. Just as we shouldn&#x

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 other words, error proportional to 1/n^2, instead of

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 quadrature or numerical integration methods instead.

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 choice have to do with infinite collections of sets, especi

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 hallucination" means that the model prod

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 discussion with my classmates (in Moscow, USSR, ca. mid-198

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 2000, the Russian navy was unable to access it for a long t

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 because telescopes gather more light than the eye per unit ti

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, Onshape is a CAD application meant for design and manufacturing

I read it online, in Russian. Well, in the late-Solzhenitsyn version of Russian, which diverged considerably from the standard language. I don't know if there is an English translation of it. I saw on a few occasions that people expres

Now you are taking this in a strange direction - it's true that there is a stream of anti-Communism or anti-Sovietism which comes from an angle of Russian nationalism, or imperialism, or chauvinism, or whatever you want to call it, but

I don't think anything good about it. Apart from the standard anti-Semitic polemic, which innovates nothing, he insulted a number of people whom he had no right to insult, and reinvented a number of episodes of his own biography in a s
