Well, then you may also appreciate changing my Nim program from the `continue` to the final output `for` to:

let mf = mopen(path)
if mf == nil:
stderr.write "wc: \"",path,"\" missing/irregular\n"
else:
var word = ""
for c in toOpenArray(cast[ptr UncheckedArray[char]](mf.mem), 0, mf.len-1):
let c = c.toLowerASCII
if c in {'a'..'z'}:
word.add c
else:
count.maybeCount word
if word.len > 0: word.setLen 0
count.maybeCount word # file ends in a word
mf.close

You also need to add ",cligen/mfile" to the import line and install a version control head of the cligen package.

With that the Nim time goes down to 6.1 ms (no PGO) and 5.0 ms (PGO). Just a quick after dinner fix-up.

{ There is actually a trick related to ASCII where we could add `, 'A'..'Z'` to the character set and then `or` in a bit to make the letter lowercase (because 'a' - 'A' is 32), but I just did the above to test that cligen/mfile worked with FIFOs in the mix, not to maximize performance. I suspect pre-sizing the table by adding e.g., 10_000 or 20_000 to the init would make more difference.}

That the big idea behind Einstein field equations: energy (and mass because E=mc2) curve spacetime and spacetime curvature affects the energy fluctuations (and the way things move).

Because both terms of the equation affect one another, solving it is complicated but here, the result is that spacetime contracts to the center of the earth.
I think a lot of that $2500 for me came from mistakes, especially with jeans. It took so long to figure out the jeans.

But it’s not the virus that caused the corrosion and the corrosion will not go away if you stop following the rules to help stop the spreading. That’s all I am saying.

As an outsider I do agree with you that democracy in US is going through a small crisis t he last few years, and in my opinion both parties are responsible for that by encouraging hate and trying to polarize people. And both parties are playing games with COVID rules which is a shame.

However by being a mask denier you don’t help fight the corrosion, you just become a pawn in their game.
The weirdest thing is that a lot of politicians are holding this up as a model for housing and a solution to what is essentially a national crisis.
> Homeless people don't aggregate in cities like SF because they have liberal policies.

Insofar as not actively and often illegally shipping them out is a progressive policy (and considering what lots of other cities do, it is), they do exactly for that reason, since it results in them having an unbalanced inflow from places that do engage in such practices.

Even beyond that, insofar as SF’s progressive policies toward the homelessness increase the survivability of homelessness more than they get people out of it, they probably, simply by that means, increase aggregation of the homeless in the city. A less progressive policy aimed at maximizing homeless misery and reducing survivability of homelessness would reduce the aggregation of homeless in the city.

An order of magnitude times a minuscule number is still a minuscule number. It would take orders of magnitudes of orders of magnitudes to make it un-acceptable levels of risk.
The main difference though is that gravitation (probably) doesn't have a mass of its own, while EM fields do. Plus, matter does not react to EM fields in the way it does towards gravitation. I.e. light is not "pulled" by EM fields. However, these are technicalities. If all matter reacted to EM fields the same way it would to gravitation, would that make EM fields no force either? Or put another way, gravitation act universally on all particles, while EM fields do not. That necessarily has consequences when it comes to relativity. However it seems odd to argue that general relativity would exclude gravitation from being a force. If it acted only on a subset of particles, it would likely be in the same position as EM fields, and suddenly become a force again?

You can't create a similar transformation for an electric field under which the motion of a proton, electron, muon etc are all straight lines.

The indicator that gravity is special is the fact that 'inertial mass' and 'gravitational mass' are the same thing.

Honest question, what is unique about Nordic culture that makes it altogether different than the UK, France, Belgium and Italy, such that Sweden is not allowed to be compared to other European countries which fared worse or about the same as they did despite draconian lockdowns? Is the argument that Nordic people are more naturally resistant to this disease and therefore Sweden could have lost fewer people? Or is it merely that Norway and Finland were able to prevent the outbreaks among their most vulnerable since they had the benefit of the virus arriving later and so they could better prepare?

The most recent stat I read showed that Sweden currently has less than a dozen people in the hospital with Covid conditions. We're 8-9 months in to this and so far the Swedes are not dropping like flies. They had an early spike in deaths and it since fizzled out.

> It's a parabola in a uniform gravity field

In relativity, there is no such thing as a "uniform gravity field", if by that you mean a field where the "acceleration due to gravity" is the same everywhere. The closest you can come is the "gravity field" inside a rocket accelerating in a straight line in empty space, where the acceleration felt by the crew is constant. That kind of "gravity field" has an "acceleration due to gravity" that decreases linearly with height.

If the mass is spherically symmetric, this will not be the case; all of the Newtonian forces from the masses further away from the center than you are will cancel out. This is called the "shell theorem", and it turns out to hold even in General Relativity.

I rarely post, so apologies if this has been posted here before, but this excerpt from a letter by Thomas Jefferson in 1807 seems relevant. In short, the problems described about modern news media are entirely true, but - frustratingly - not at all novel.

"To your request of my opinion of the manner in which a newspaper should be conducted so as to be most useful, I should answer ‘by restraining it to true facts & sound principles only.’ yet I fear such a paper would find few subscribers. it is a melancholy truth that a suppression of the press could not more compleatly deprive the nation of it’s benefits, than is done by it’s abandoned prostitution to falsehood. nothing can now be believed which is seen in a newspaper. truth itself becomes suspicious by being put into that polluted vehicle. the real extent of this state of misinformation is known only to those who are in situations to confront facts within their knolege with the lies of the day. I really look with commiseration over the great body of my fellow citizens, who, reading newspapers, live & die in the belief that they have known something of what has been passing in the world in their time: whereas the accounts they have read in newspapers are just as true a history of any other period of the world as of the present, except that the real names of the day are affixed to their fables. general facts may indeed be collected from them, such as that Europe is now at war, that Bonaparte has been a successful warrior, that he has subjected a great portion of Europe to his will &c &c. but no details can be relied on. I will add that the man who never looks into a newspaper is better informed than he who reads them; inasmuch as he who knows nothing is nearer to truth than he whose mind is filled with falsehoods & errors. he who reads nothing will still learn the great facts, and the details are all false."

Also some of the frequency spectrum lopsidedness could be explained by the properties of our ears, to which modern music is acutely tuned.

It's all good. Indeed, the medium we use sometimes comes across poorly.
The curvature does indeed depend on the ball's mass. The contribution to spacetime curvature the ball's mass brings to the table is extremely small compared to that of the earth, and the contribution that comes from the (massless) photon's energy[0] is smaller still, but they both influence the spacetime curvature.

[0] Photons bend spacetime according to GR, although as far as I know this has not been proven experimentally. We'll probably need a theory of quantum gravity to be sure.
> I've always wanted to know why a ball doesn't follow a beam of light if they are both following straight lines in spacetime.

Because they're following different straight lines in spacetime. Roughly speaking, if you pick a point in space and a particular direction in space from that point, there is a continuous infinity of possible straight lines in spacetime that point in that direction in space. One endpoint of that continuous infinity is the worldline of a light ray. The ball's path is somewhere in the middle of that continuous infinity.
I'm not aware of any game engines that simulate general relativity / 4D spacetime.

I think what you may be noticing is that, as you reduce the tick frequency of a newtonian physics simulation, parabolas become less accurate as integration error accumulates.

Indeed, to apply any form of "denoising" is to presuppose what the "true" underlying sample looks like. All of these strategies that people like to apply, whether they know it or not, directly impose a model onto the initial dataset.

Once measurements are digitized, the uncertainty within the dataset is baked in and cannot be removed. Without external information, the best estimation of the distribution from which the data are drawn may be found within the data themselves.

> The difference is that light travels through space, but not time

This is a common pop science statement, but it's not correct. A correct statement is that the concept of "speed through spacetime", which is what has to be split into "speed through space" and "speed through time" in the pop science statement, does not apply to a light ray.

In more technical language, the tangent vector to the light ray's worldline is not a unit vector, it's a null vector, and the concept of "speed through spacetime" only makes sense for a worldline whose tangent vector is a unit vector.
> So if you want to be really pedantic, it's never an ellipse because the Earth is not a point mass.

This turns out to be not pedantic but very important if you're guiding an ICBM. And when landing on the Moon, Apollo had to deal with irregularities in the Moon's gravity due to mass concentrations, called mascons.

(If you're interested in missile guidance, take a look at the book Inventing Accuracy. Among other things, it discusses some of the efforts to map the Earth's gravity field to increase missile accuracy for Trident and Minuteman missiles. I knew a physicist who worked on this.)
If that isn't a fantastically deceptive piece of marketing then I don't know what is. It writes as if other salt deposits didn't originate in some kind of ancient body of water, and it uses the fact that they're harvesting a brine to imply that the entire bloody ocean is still hiding under the Appalachians, so that by buying their salt you're buying "sea salt" (and all the naturalist voodoo that might entail) but without any of the contaminants of modern oceans. Being low in mercury and whatnot seems like a good thing, and their salt is probably fine, but that marketing is something else.

Yes, history repeats itself. However I guess the person who "never looks into a newspaper" remains informed through people who do read it at least from time to time. I would wonder why "Europe is now at war", even if it's speculation, since that sort of thing is often highly subjective (see: Armenia and Azerbaijan right now). IMO, getting "nearer to truth" is possible through collective effort. If we all make no effort at this, then it is simple for a despot to take over.

Democracy's burden is that some responsibility is placed upon all of us to contribute to sensible policy through discussion and voting. It is on us to interpret which part of history lines up with today.

And I'd argue reading opinions is helpful too to practice learning how to influence others. One take away from Jefferson's opinion here is "don't listen to them, listen to me."
Actually it's quite easy to cast electromagnetism into a purely geometrical form, you just add a few extra curled up dimensions to a flattish spacetime in general relativity and you basically get Maxwell's equations for free. There are other reasons that's not a great theory (IIRC sources and self-action get nasty and you have to make arbitrary choices about scale, etc), but it's straightforward to get force laws out of pure geometry.
