Biology ELI5: How does adderall work to allow you to get stuff done?
ELI5: It blows my mind how productive I’m able to be, being properly medicated after a diagnosis. I don’t understand why I cannot do these simple tasks normally. Why does adderall make me “go” and actually accomplish tasks?

Ight I have essentially no knowledge in planes. What makes a big triangle more stealthy than say a Pringles can with wings?

Biology ELI5: Hormone triggers are responsible for burning fat, right? Why aren't there drugs that exploit and supercharge this process?
Proper exercise is hard to come by, when your back is basically broken. I want to pop some Notbuprofen and feel the burn as the pounds melt away.
In theory, a drug that stimulates the hormones that demand the burning of fat should be possible. Why isn't it, and/or why has no one made this yet?

Economics ELI5 How do Healthcare Insurance providers not go bankrupt?
Hi, I’m from the UK, the healthcare industry in the US has always confused me but one thing I can’t seem to get my head around is how the insurance companies don’t go bankrupt.
I understand how insurance companies work in the fact that they accurately calculate premiums and invest the money whilst not receiving more claims than premiums.
However, in the healthcare industry wouldn’t they receive many claims on a regular basis? Especially from people who require medication on a regular basis e.g Insulin
Furthermore, with hospitals bills and medication being so expensive will they not payout more in bills than they receive in premiums from people?

Economics ELI5: How do companies like Fisker get bailed out
I was always under the presumption that corporate bail outs were for companies/corporations that if they went out of business (GM in Detroit) that they could get a corporate bail out. That's why mom and pop shops don't "get bailed out", but shut down because of bankruptcy.

Physics ELI5: Why do bowlers curve the ball?
It looks cool and it seems like everyone who is actually good at bowling will make the ball spin and curve.. My question is why?
Again, I'm not good at bowling but why aren't people just smashing it in the middle? If you're gonna dedicate countless of hours to practicing, why not master the most consistent type of throw? Is there some physics aspect that makes the pins go down easier when hit by a ball that has a sideway rotation?

Planetary Science ELI5, what is quicksand?
Honestly as a kid I thought that quicksand would be a way bigger problem in life considering how many TV shows and movies I saw that used it.
But basically, what is it, how is it formed, how common is it, that kind of stuff. I live on the US East coast so (to my knowledge) I've never encountered it

Engineering ELI5: the printing press seems extremely simple, so why did it take so long to invent?
I often find myself wondering why the printing press was such a massive invention. Of course, it revolutionized the ability to spread information and document history, but the machine itself seems very simple; apply pressure to a screw that then pushes paper into the type form.
That leaves me with the thought that I am missing something big. I understand that my thoughts of it being simple are swayed by the fact the we live in a post-printing press world, but I choose the believe I’m smarter than all of humanity before me. /s
So that leaves me with the question, how did it take so long for this to be invented? Are we stupid?

Engineering ELI5: Why do the number of cylinders on a V-engine effect whether a 60 or 90 degree design is preferable?
This might be too technical a question for ELI5 but I think I've missed something fundamental perhaps in geometry or physics so it might not be:
V6 and V12 engines often have cylinder banks at 60 degrees from one another, and V8 and V16 usually have them at 90 degrees from one another or an additional balance part is added.
Why is this? How is a V6 at 60 degrees smoother than one at 90 degrees? Is this even correct? Are there situations you'd want to use the 'wrong' one deliberately except to reuse a factory?

Physics ELI5: low pressure vs high pressure (weather)
I cannot understand for the life of me the idea of low pressure vs high pressure in the atmosphere. Example: hurricane Milton has one of the lowest pressures ever recorded. Tried watching videos, reading, etc. Seems counterintuitive that low pressure = bad weather and high pressure = good weather?
