The asterisk shows that Finnish is in category 4.5. That's harder than Russian!

Didn't some of his own party members accuse him of anti-Semitism? There was a television documentary about it.

My mother only found out she had cancer when she saw a GP for an unrelated condition.

One person I'm speaking to claims that the NHS hires too many bureaucrats who are impossible to fire, and who he believes provide the doctors with too much paperwork. He suggests that instead of paying those bureaucrats, the money shou

It's still difficult for a lot of people to get a physical exam by their GP. My own mother had her breast cancer diagnosed pre-pandemic only after she came in with an unrelated problem. Many health problems are not being caught while G

I'm suggesting maybe writing the Lebesgue measure as 1 so the Lebesgue integral of a function f becomes ⌠ | f(x)⋅1 dx ⌡ The logic is that the Lebesgue measure is a density which is everywhere

> If you treat function as a system that produces an output given an input - does it matter if it is a graph or a probability distribution? Because that's wrong. For example, take the Dirac delta function (point mass). You can only

I find the following remark by Rota interesting: Insofar as the Laplace transform goes, two radically different uses of the word “function” are dangerously confused with each other. The first is the ordinary notion of function as a somethi

You don't need to understand long division to be able to do that. Long division is over the integers. It's got a weird notation, and I never learnt it. There isn't any reason for 99.9% of mathematicians - even in abstract alg

I just realised the OP probably used a Fisher test or something like it. The Bayesian approach isn't necessarily better then.

How would you test it? There's lots of factors influencing someone's psychology; how would you pick them apart to prove causes? The field's dumb.

The following is a Twitter account which only posts snark about the "field" of evolutionary psychology: https://nitter.cz/evopsychgoogle It's a bunch of postdictions and unfalsifiable just-so stories. It also

Good catch! I'm more inclined to use a Bayesian approach here because we can't be certain about the probability of either population becoming infected. The 80% Credible Intervals for the two Beta distributions overlap: [1] and [2]

Software's an area where fail-fast/fail-hard is commonplace advice. People often compile their code with -Wall. Secure defaults are like -Wall. Security's a thankless area since you have no way of knowing which exploits were

I imagine it isn't. It's simply something you can mention during drinks. And the correct term is laird btw.

Maths papers aren't easy to write or organise. And whether a paper is well-structured is somewhat subjective unless we're writing for computers. That's not enough to knock it down.

This might be it. Good catch. A machine that can perform all integer arithmetic operations (+, -, *) in constant time can solve all problems in PSPACE in polynomial time.

Haven't dual quaternions taken over for their ability to represent all rigid body motions? Quaternions are still important for building intuition for dual quaternions.

I have only a passing interest but Rust is based on ideas in the late '80s concerning linear logic and affine logic and their relationship to PLT. Monadic programming and its applications to for instance parser combinators is from the

To me, this seems subjective and grouchy. It might be that when you were growing up, things were a certain way, and now they're a bit different. You have a minor aesthetic disagreement. Some people like the shaky cam.

The eigenvalues and eigenvectors are going to be complex some of the time anyway. So I agree, why not just copy-and-paste the real algorithm (or use operator overloading) while remembering to insert complex-conjugates? It's educational
