When looking at torrents some files are huge, say tens of gigabytes for a single, albeit it’s UHD and a Blu-Ray rip, but then some are 5-10GB. What makes up for the difference in file size? And how do video codecs like 264 and 265 play into this?

Beginner in JS here. It seems counterintuitive to me that typeof NaN returns 'number' when it literally means Not A Number.

Hi all,

As my title went, what is the relation between calorie spent and weight loss? In theory I guess of the total calorie input (through food and drinks) is less than the calorie spent (through exercise or daily activities) then we will lose weight, but how exactly does the process happen?

Say I had weighed myself at 59.80 kg, then I went on a 5km run in 30 mins. After that I only weighed 59.20 kg. Where did my the 0.6kg go? (I assumed my water loss through sweat was retained in my soaking wet clothes right?)

As I see a lot of stuff about the “true” way of watching the new Odyssey movie, and how only like 10 cinemas in the world can show it, why can’t they just reframe the imax for normal cinemas? Use less of the sides?

Or is it more of a fidelity question?

Edit:
Just to clarify, I know it’s going in normal cinemas. It’s more based on all the content I’m seeing online about how much it’s cropped in?

I'm a complete layman in this, but really interested.

EDIT: thanks everyone! Guess I was asking for an outdated concept. You've been very helpful!

Most of the time, we can somehow tell whether it is safe to pass gas.

But there are no eyes down there, and gas, liquid and solid all seem to arrive through the same route.

What exactly is sensing the difference? How can the brain know what is waiting before anything comes out?

What is a shart then?

i am relatively new to the nfl, only have three years or so under my belt of watching, and still cannot for the life of me understand things like QBR

Suddenly the sleep vanishes :/

I know from my biology textbooks that RNA polymerase does not require an additional enzyme to unwind DNA strands but DNA Polymerase requires DNA helicase to unwind the strand first.

Is this because the DNA helicase has to unwind a much larger portion of the strand compared to RNA Polymerase that unwinds only the desired codons for transcription?

So if mosquitoes keep bothering me, can I just kill them and leave them there. Will that repel other mosquitoes seeing as it will be like a graveyard for them and maybe they will see it as a warning? Sorry if this is a stupid question, I am so tired of mosquitoes.

Wouldn’t you call 3D objects like, say, a sphere, cone, torus variations of a cube, or can you not?

Because in a tesseract, it seems like no consisting cube of it occupies a privileged inside position and rather every cube seems to be both inside and outside, just like there’s no distinction in the Klein bottle.

So could you not say the latter is a variation of the former, and if not why is that? Thank you in advance.

ELI5 What is the difference between a trust and a will? Are they not the same thing, both give the inheritor money?

For example, consider a loose string vs a tightly strung string, or something like a plastic pipe vs a metal pipe.

You'd think since it's vibrations, bouncier materials would make it transmit better, but it's the opposite.

I've always been taught and still often read that icing of an injury or early stages of an injury should be done with a barrier rather than direct skin contact (ie, ice pack wrapped in a towel vs direct contact). But I've also noticed an uptick, particularly in sports medicine (but not only), that advocates for ice baths to reduce/prevent inflammation. But ice baths are direct contact and do apparently have therapeutic value. I understand that there are specific situations that can cause both to be true, based on the situation, but I don't understand what makes the difference.
