like, I know what a zero is, and also what a function is sometimes even how to calculate them, bo idea of the difference between a trivial zero and a non trivial one

I’ve always wondered how it can be the exact same temperature on paper, but feel completely different depending on the weather.

Like, 15°C can feel freezing when it’s windy, weirdly warm when the sun is out, or uncomfortable when it’s humid.

What’s actually happening to our bodies that makes the same temperature feel so different? Is it mostly about how quickly we lose heat, or are there other factors involved?

I randomly came across this term "high-density life" in a self-help kind of article or speech. It says strong people live their lives with more "density". And these strong and successful people manage to experience more, create more, complete more and stuff. I feel anxious when I read it because I can't help feeling that I'm wasting my life.

What do you know about "life density”? Do you think the whole concept exists? What do you do to make your life "denser" if you agree on this concept?

What is the benefit of having the cell body in different locations? What factors do neurons used to communicate with each other so that they can for complex circuits, and what determines if a neuron is stimulatory or inhibitory?

Given the rather distinctive makeup of Staten Island vs. the rest of New York City, there must be some good reasons why secession hasn’t been allowed to happen and why SI hasn’t been preemptively kicked out of NYC.

I’m interested in understanding what those reasons could be at a basic level.

I understand the fundamental laws of thermodynamics well enough. But since CPUs, GPUs, other microcontrollers are not actually doing any “work”, is it theoretically possible to minimize Joule heating and consume little to no power for computing applications?

Connecting two other ELI5s. This is something that I've always struggled with.

Space is nothing. There is no actual "fabric" of space. There are things in space, and the "space" in between is.. nothing.

Nothing, as I understand it, is without mass, energy, information, anything. There is no thing to bend.

But! Gravity doesn't bend light because light doesn't have mass. It bends space and we see light bend along it.

How can nothingness be bent?

And why doesn't light just pass through empty nothingness on the same trajectory, if it isn't being acted on by gravity? OR is it that it does do this and it's only our 3D perception that it has changed trajectory?

When we talk about gravity bending space, are we actually talking about the distribution of Stuff within a given area, as it relates to another body, due to the effect of gravity? e.g. the distribution of Stuff around a random planet

I know this is very long and contains multiple questions. My hope is that by including all of this, it will make clear where my misunderstanding is. The real question is, how can nothing be bent?

If doctors say a surgery has a 1% chance of causing death, does that literally mean that if 100 people undergo the same surgery, 1 person would be expected to die and the other 99 would survive?

Does that percentage apply to every specific person, if that's the case wouldn't that mean, theoretically, every healthy person should survive out of the 100 people since every person has a 99% chance of not dying?

don’t speak Korean but kpop songs get stuck in my head for like days and I can’t make them stop. Is it the hooks or the beats or just how much they repeat the same part. Maybe it’s something else I’m not thinking of. I don’t get why they stick so much more than other pop songs

I've been seeing people talk about these things called "liminal spaces" lately mostly on posts with weird looking pictures of empty places. I don't really know much about them but I'm kinda curious. What exactly makes a place liminal?
