Reply to comment by Tounsk in ELI5 Why aren't we curing more degenerative diseases with stem cell research? by KaishiXYZ
Is there a similar treatment for restoration/replacement of neurons affected by MS (if we assumed that the progress of the MS could be halted)?

With the speed of sound traveling so fast, how can it reach the headphone, and the headphone have time to analyze and produce a “matching opposite” so quickly?

Reply to Eli5 what exactly causes the sensation of feeling thirsty when we are dehydrated? by crimeoutfit
When you’re dehydrated, you have less water in your blood so the blood becomes more concentrated and blood volume decreases. Your kidney is used to filtering all the blood, so it can feel when you have less blood to filter, and it releases hormones that help increase your blood pressure and decrease the amount of water in your pee. A special part of your brain samples your blood and can sense both the kidney hormones and the increased blood concentration. This brain part sends signals to the area responsible for thirst, turning the thirsty feeling on.

That's my point; I'm not assuming it is a right triangle, but when the construction is drawn I (even if not you) can see that it must be one. I've even given you a couple of interim steps to seeing why this is so, but you don't seem to grasp it even then.

There's a third kind that's used for gun hearing protection. Shooters earmuffs use passive noise cancellation, but also have external microphones and internal speakers. When you wear them, the microphones transmit sound to your ears. But they will not transmit any loud noises such as gunshots.
The result is that they give you super sensitive hearing. But there's no risk of hearing damage, because if the electronics fail or the battery goes dead, you're left with passive noise cancellation.

I may suspect you have not gotten told what half-time is? :-)
Halftime is when half of the product is gone. Let's say you have 100mg after 10 minutes is only 50mg still active, again after 10 minutes is 25mg still active, 10 min more 12.5 then +10 minutes 6.25mg, now 10 min later 3.12mg and that keeps going on.
For every 10 minutes is the product's strength half. It's whole time depends on when, what is left, is too little to do anything.

Reply to comment by ChickenEnthusiast in ELI5: Tech billionaires lost $400 billion this year. Where does it go? Does anyone gain? by ChickenEnthusiast
All that’s going on is they own something (often a company they created) that has an estimated selling price, but they aren’t selling it so it doesn’t really matter. Their situation doesn’t change much because they weren’t selling it anyway. The comparison to houses was apt.

Yep. The tradeoff is that digital crime has increased significantly, since your money can now be stolen by people anywhere in the world.

Reply to comment by Officialsparxx in ELI5: How web crawlers and other engines don’t constantly get infected with viruses? by Officialsparxx
It's like instead of clicking on a link you right click and select save target - that's how mirroring works - they just download the files. You're not rendering the page just downloading one file.
It's only when you open the downloaded file with a browser that it is rendered and possibly included javascript code is run, which can exploit some weakness in a specific browser.
Similarly to downloading malware - It doesn't do anything until you run it - but you can open the executable with a decompiler and look at what it does without actually running it.

Hopefully you’re able to at least justify the wishlist.
“This fancy computer will run CAD more efficiently, saving time, and allowing the engineer to process more projects throughout the year.” - especially when the unit was due for replacement next year anyways.

Ok buddy, what happens if it isn't a right triangle? Never heard of a rhombus?
Also, you keep using the words "formal algebra". I don't think they mean what you think they mean.

Reply to ELI5: Why does putting one foot out from under the blankets bring so much relief of heat while laying in bed? by SirDuke6
3 main heat dump locations on your body, your palms, your upper cheeks and forehead, and your bottoms of your feet. Combine that with venting an already hot and contained area and you get immediate relief.

I thought about it for a few minutes longer and realized this can work because your wearing something right next to your eardrum. Before I was thinking how could sound be cancelled, if I yell at a concert when the band is playing my yell is still there but it’s drowned out, but I guess because the headphones are right next to your ears that must be a big part of why it works.

It's a little bit less magical than what people are suggesting here.. You don't actually hear as well, so to speak, as a microphone. So there's enough time to invert the soundwave and play it back before you start picking up the vibrations that produce sound you hear.
Alternative way to think about it - you delay the incoming sound slightly and then play it back as perfectly out of sync as you can. The question really is the response, and how quickly you can generate the wave accurately.
The trick is that you should be producing a sound-wave that sounds like what is actually heard behind the clogs, for example. And you really don't want to play back a really, really loud sound, or increase the wave too quickly based on some extrapolation, etc. And it's typically not perfect, so you get noise. You can also mask it all and increase response, so to speak by having a noise-floor.
But yeah, if you play back some fairly low volume sound where the noise is not physically noticeable, and you allow for some noise on the bottom here -- an exactly out of sync wave is going to cancel the sound out, in the sense that your ear is not going to vibrate and make you hear sound.

Reply to comment by stilsjx in ELI5: Why do companies require annual budget be spent 100%? by angrybird7677
I don't think it's this half of the situation that people get confused by. What's confusing is that giant companies don't take a more sophisticated approach to things (or at least, many don't).
I work in quite a senior position at a big company and my boss sent an email several weeks back to me and other managers that was basically just 'we have lots of money left, send me your wishlists'. You would think that the company would realise what's happening when every year every department orders a bunch of fancy expensive tech in December, but it seems not...
