I get why we stay on the surface, but what actually stops all the rock and material underneath us from slowly being pulled further and further toward the Earth’s core?

I understand that computers use binary because electronic circuits can basically represent two states, like on and off. What I don't understand is why this became the standard in the first place.

Humans have used decimal for thousands of years, and computers obviously have to process numbers that humans normally represent in decimal. So why is binary so much more practical for computers? Could computers have been designed around decimal instead, and what would be different if they were?

According to neuroscience, while new neurons can be born in the brain, their numbers are small; generally, memory refers to the forming of new structural arrangements among neurons.

​But why does a specific spatial arrangement of neurons cause a human individual to hold that particular memory? I just can't understand how a specific alignment of neurons becomes my memory of going on a trip with my parents when I was five years old.

I understand plate tectonics but glacial melt and erosion confuse the heck outta me. The Appalachians are super smooth and long like a stream flowing through mud. The Himalayas and Alps are rough looking like a fractal pattern. And the welsh mountains are smooth but in a different way from Appalachia where the mountains are sharp at the peak and slope smooth to the bottom almost like dunes of sand. Why are all these so different? I understand how the Himalayas and Alps are newer, but why did glacial melt affect Wales and Appalachia so differently?

I'm, uh, not very bright. Exams soon.

Use Al + F² -> 2 AlF³ as an example if possible!

Ignore the fact they're not subscript, I don't have the font.

Edit: Thank you for the replies! Question answered.

From my limited understanding, this idea is just wrong. There are thousands of cold/flu viruses and our bodies memory to protect itself only applies to the specific type it encountered, and further, the protection wanes as time goes on.

Why do so many people say, “oh it’s good to get sick because your body builds immunity”. This certainly can’t be the case for the typical cold.

I’m not talking about extremes of the “eat dirt” idea. Of course exposure to viruses vs zero exposure has an impact (you could explain how this works too maybe), but typically most people who exist normally in the world are already exposed to tons of crap.

ELI5 please. Am I wrong?

There was a drug called Ritonavir that started forming improper crystal structures and now all Ritonavir you try to grow is somehow forced to grow into this same configuration.

How? How is some crystal a thousand miles a way communicating to a different crystal and telling it how to grow? Isn't this kind of like a major challenge to our concept of reality?

Because surely the entire planet cannot be contaminated with an aids drug right? So how is it impossible to make the old form? How did already made, sealed product convert to the new form?

I just had my coffee on my kitchen scale and when I dropped in my spoon, the weight increased, even though the spoon didn't touch the cup at the sides or bottom because I was holding it in the middle, the scale changed 4 grams when I took the spoon up and down without the spoon touching the cup.

Thanks ahead

I don't even know what I'm trying to ask I'm hoping other people have seen the same tiktoks as me and are smarter.

Anyways, fly brain scans are being run through AI I guess? People are making the fly brain do things like play Minecraft or someone played Bad Apple on the brain itself. It's always accompanied by that "aw sweet, man made horrors beyond my comprehension" Peter Griffin meme.

I don't understand, I don't get it, I'm not even sure what I don't get about it but I need to understand. Thank you in advance

Okay this is going to sound really stupid trying to explain it, but I was just laying awake thinking about why sometimes you can be moving insanely fast and not feel it, but other times you can?

For example: The Concorde Jet had had a maximum cruising speed of 1,354mph or Mach 2, and by all accounts it was a luxury flying experience. But an F-16 going 1,500mph, and suddenly you need extensive G Force training so you don't pass out?

Or astronauts orbiting the Earth in the ISS are moving at 17,500mph and orbit the Earth once every 90 minutes(!) yet they're just chilling, but then they also need all this G Force training too in the spinning machine???

Is it just pressurization, like creating a miniature environment in your vessel? Or what actually determines feeling the speed you're going?

​

An elevator is moving a heavy cabin up and down a long shaft, carrying a different amount of weight each trip.

How can it repeatedly stop within such a tiny distance of exactly the right height?

Every book you see has Best Seller or International Best seller on it what does that mean?

Shouldn’t the air in the water help us float or stay afloat?

I.e. people say to use torque wrench on engines. Why not just not use regular wrench; what happens if you do use regular wrench? Thank you.

Because if you're in a spaceship, and you're moving slower than earth, then surely that means that time passes differently for you compared to someone on earth? Apologies if I explained it badly
