The first part likely is just an artifact of an unwritten common assumption. That is, it's probably 96% of women, who lived to adulthood, who were ever married.

It's not processor op-codes, but sure it's part of the software. You wouldn't say that a set of precomputed weights in a numerical integrator aren't part of the software, would you? Or say that the graphics in a game are

It depends which side you are doing the multiplication on? Most linear algebra textbooks work matrix-vector, where the vector is a column vector. In that arrangement, the resulting vector is formed by dot products of the rows of the matrix

I'm a mathematician. It's kind of a strange statement since, if we are talking about a matrix, it has two indices not one. Even if we do flatten the matrix to a vector, rows then columns are an almost universal ordering of those t

You could definitely replace "Tuesday" with something like that and part of the pedagogical purpose of the problem is for people to question this. The actual effect comes from not distinguishing the boys. That increases the likeli

But correctly formatting references is pretty much a solved task through reference managers, possibly plus bibtex. It's a well-defined task, after all, and well suited to traditional software techniques. [1] If someone used an LLM to f

That's not what was being said. They are saying that when your body does something different, in this case producing fever, it is (often) because of a change in the level of some number of proteins. You get new copies of proteins throu

I feel like the main thing that this will accomplish is to show that the quality of peer review is quite spotty. Usually 1 of 3 truly read and understood the paper enough to critique from a place of knowledge. Entirely miscategorizing a pap

Having lived within a block or so of the place being described, 125th is a pretty accurate placement of the Harlem's southern border west of Broadway. (Maybe a bit more south at St Clair place.) Further east is different. I can't

As I recall, most of the complaints about big pharma were about price-gauging. This is entirely different.

So, by "men", they mean 15 or older. Median age of first marriage is ~30 for US men.

Mathematician here (trained as pure, working as applied). Non-elegant proofs are useful, if the result is important. e.g. People would still be excited by an ugly proof of the Riemann hypothesis.^1 It's important too a lot of other th

On the 3 points bit: One and two points are special. In each of these cases, there is, up to translations and uniform scaling, only one configuration. When you have three points, though, there are as many configurations as there are similar

Instead of trying to fit a sine wave this way, one can also take the Fourier transform and read off the largest value and its location.

A lot is lost here by using notation that looks like it is rigorous math, but is actually pretty vague. For example, are X and Y indicators for the same flip? If so, they are mutually exclusive, X=Y is contradictory, and hence P(X=Y)=0. If

The rest are different, but in the several US localities I've lived in, water and sewer are paid as separate metered services. (Only the water is metered, the sewer is billed proportionally to the water usage.)

I would read all more formally as: for each element in this list, the element is true. Then you get a vacuous truth. (Think about the negation: there is an element in the list which is false. That's obviously false.) Any would be more

No, there is nothing all that specific about vector spaces. This is true about general algebraic structures. What you want to care about here is preserving structures: How would you define addition on a disjoint union? e.g. If you have V⊔W
