Unfertilized bird eggs are single cells, fertilized eggs should be multicellular by the time they are laid.

Fencepost errors aren't errors if you are actually trying to count fenceposts.

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…

Nope. 31% German, 27% Autistic.

They said that they were going to be blunt, not terse.

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…

I don't know, but I've never had trouble with mud daubers.

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 c…

> Institutional administrators confiscate 50, 60, 70% of every research grant. Not even the Trump admin is alleging levels of indirect costs that high. See e.g. https://grants.nih.…

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 …

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 tradition…

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 n…

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 critiq…

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…

> This is why, Prof. Wildberger says he "doesn't believe in irrational numbers." Oh boy, I hope that they missed a joke or misquoted.

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 Riem…

Not a question of merits, but of how to make sure the journal really had acquired the rights to publish the article.

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, t…

Pretty sure this person meant singular as in singularity, not singular as in one.

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 mutua…

Looks like he figured out the problem by at least 2007: http://www.melbochner.net/exhibitions/gabbiano-rome-2007/

> As others have noted, exponential smoothing has a different problem, that it asymptotically approaches but never quite reaches its destination. The obvious fix is to stop animati…
