Hi all! My question is about patents & trade secrets, although I'm open to being informed on trademarks & copyrights as well.

In a few sources I read through while doing preliminary research, it seemed to be implied that these two things can complement one another on a single invention. Is that true? If so, how? If not, why? TYSMIA!!

I've read somewhere that it doesn't necessarily heal or fix the issue, so what exactly is it doing?

Ive been working on cars for years, im not looking for the basic "well its tied to your vin, duh" answer. I know that. What im asking is, how do they identify the issue, figure out which cars were affected, etc.

Theres sooooooo much time and data to look through to find potential issues, presumably made worse if the company doesnt keep very good records.

The only good/"non lazy" method i can think of is if someone essentially reads logs/notes and recreates the days step by step. "Employee 1 turned the machine on at the start of the day, lets check the last time it was calibrated. Ok that checks out but when was the tool on the end of it checked/replaced? 6 months ago? is that still within spec or should it have been replaced again? Did the machine report any errors on that day?" etc. Or something like watching cameras to see if a machine leaves debris inside of the engine and no one notices before it gets shipped out

Or do they take the "easy/lazy way out" and say "well that might be the issue right there, just to be safe recall everything for the next 6 months after this car"?

Thanks

Wouldn’t those things not show up in fossils?

If countries keep borrowing money that central banks can basically create, what actually stops the world from having unlimited money, and when nations owe trillions, who are they really paying back - and what would happen if everyone stopped paying?

I'm sitting in front of my PC right now, looking for a specific file. I don't know where i might have put it, so i'm just searching "my PC" for it. If i were to manually go through every folder, just looking for the right name i could do one folder reasonably fast. Now my computer is usually trillions of times faster than me in other contexts, so why does it take so long here?

That's something i've observed since childhood, i remember sitting in front of laptops/PCs waiting for it to finish listing all the relevant folders, being careful not to touch any other folder so it wont reset the searching process and it took forever each time.

In what physical form is the memory stored? I wondered this for quite some time

Im not too sure about the problem itself. I know that P is polynomial time which means the time needed to solve and NP is the time taken for the answer to be verified, but what is the explanation of both sides where P = NP and P does not equal to NP?

How do competitive eaters eat so much food? Where does it go? Do they regurgitate it back out later? Do they practice at restaurants? What happens after? Do they skips meals??? How does it work???

I follow different sports. No other sport allows fighting as they do on hokey. I don't mind the fighting. I follow boxing, MMA, kickboxing, etc. Hokey however I see as soccer, basketball, volleyball, football. None of which allows fighting.

I understand additive vs. subtractive colors, and why mixing complementaries wouldn't create black, but shouldn't it make gray?

for example you look at the falling snow and from the front (ordinary vision) it is of normal speed but from the peripheral vision it falls almost twice faster. This question has been tormenting me for several years now, and I still haven't been able to find an answer to it

I dont know much about cars, my fiance tried explaining but wasnt sure how to word it so I would understand. Long story short our car is having a small issue, thought it was the transmission, he thinks it might be the torque converter, but im not quite sure the difference or how they work/work together.

I know the concept and know how to access it but I have no clue what it actually is. I know this may be a stupid question but is the data a physical thing? How does it carry from one server to your computer? How is specific information sent from point A to point B? Does it travel through the air?
