>This isn’t merely semantically incorrect because it suggests the use of time travel, it’s grammatically incorrect because the verb is just conjugated incorrectly for the tense of the sentence.

No, it's not. The point in "will run yesterday" and "sleep furiously" is actually exactly the same: Grammatically correct, semantically nonsensical. The effect of "yesterday" really isn't any different from "furiously" here, as it does not influence the grammatical tense. They are just adverbs that add meaning that is nonsensical. They're just sitting there in their correct grammatical positions. There really is nothing wrong with the conjugation of the verbs - It would be wrong it if it was "will ran", for example.

I am stupid and can't function before I've had my first coffee in the morning. Because my caffeine addiction impacts my brain like this, sometimes I mess up a step of preparing my coffee. If I don't put the carafe in properly and hit brew anyway, the coffee would brew and spill all over my counter. The people designing the coffee pot were smart, and knew that dumb people like me exist, so they installed the contact drip to prevent me from ruining my counters.

Afaik digital cameras don't generally use subpixels. Each pixel is roughly speaking only able to detect one of red, green or blue light - because it's covered by a filter that blocks the other colours. So if it only detects the red part how can we see whether or not there was a green thing there when we look at that pixel in the image? A computer has to guess what the colour is in that precise spot by using information from the neighbouring pixels.

That guessing is called 'debayering'. It means that effectively the image captures black and white textures in much higher resolution than variations in colour. Generally that fits well enough with what we want to look at and how we see things.

Our eyes are more sensitive to green light than to anything else, so they make cameras to match. Half the pixels are sensitive to green, one quarter to red, and one quarter to blue.

This is different from grammar rules. Because this is not a grammar rule - at least, not one that we discovered yet. We just don't know why they have to be in this order.

And in fact, as for breaking rules: It's the other way around. Grammar rules can't be broken or they'd produce ungrammatical gibberish. But this adjective pattern is kind of a soft, fuzzy "rule" that does have a bit of flexibility some of the time.

Slight correction, but that's generally correct. Iron has the lowest binding energy per nucleon, and adding a proton adds the energy to add that proton in to the nucleus as well as energy needed to keep all the existing nucleons together with it, which ends up being more than just adding a proton and keeping all else equal.

The reason for this is quantum mechanical in nature and involves the strong force. It has to do with the strong force being strongest at certain distances before falling off rapidly, and protons don't naturally want to be near each other because they are both positively charged. It also involves spin and nuclear orbitals and other fun things, but the intuitive not really but kind of right idea is that the nucleus is getting large enough that the nucleus is getting large and complex enough that it takes more energy to keep them all together happily and not wanting to change to a new configuration.

This is true; however, there are some strong ramifications to Facebook and Twitter being basically the public square of the Internet that aren't properly addressed by simply stating that the First Amendment always constrains the government and frees private actors to do as they will.

The platform vs publisher dichotomy embodied in the Section 230 debate is one such place where they resurface.

Space and time are related. We call them together 'spacetime'.

You have a limited and fixed speed through spacetime.

If you are statioanry, then all your speed goes into time. You get to go the maximum rate through time. We'll call it aging 1 second per second.

If you move, then you have to split your speed between time and space. If you move slowly through space, then you might age 0.999999 seconds per second, which is hardly a ntoicible difference. If you move very fast through space, then you might age 0.10 seconds per second, which is a very noticible.

Some objects move just fast enough, and need precision timing enough, that we notice it. Like software that works with GPS satellites needs to account for the tiny time dilation between them, because that tiny difference would make a difference in where the GPS believes you are.
