What separates human intelligence from artificial intelligence? Isn't the brain just complex processes?
22 posts and 3 images submitted.

sexual reproduction
mortality

things like that

consciousness.
Then again, it could just be that I am the only actual living thing in the entire universe while the others are just complex systems that behave according to the laws of nature.

I think that it's the many mannerisms, tendencies, and outlooks we have developed as a species from evolution.

Artificial intelligence would have no reason to exhibit these traits.

Not a good argument. They could just make their presence unknown or have gone to a time before they could make all of humanity be aware of their existence. Or they could be on separate time lines (universes) than our own.

The conclussion is based on no facts. As we have no idea how or IF time-travel works. Any conclussion is in itself fallacious
Any.

How do I study Physics, /sci/? I'm a mechanical engineering student and I am very interested in being as good as Physics as I possibly can. I'm willing to dedicate as much time as possible to it.

Give me everything you've got, be it study tips, textbooks, online resources, encouragement, etc.

>How do I study Physics
The same way you study everything else, you read and do problems until you understand it. Also picking the right place to start is very important, for example stating classical mechanics with Goldstein would be stupid, start at the bottom (Gregory is good classical mechanics text). I know it sounds obvious, but I tripped up here when I tried teaching myself group theory. Also >>7956746 is partly right, a get a good mathematical methods book and you won't go far wrong, I'd recommend Riley et al.

I have a great idea for a kids toy that people have already been stealing from me in concept, because i talked about it online and faggots think they have a clever design when mine will blow everything out of the water.

Google how to file a patent dude.

Goddam my college education wasn't the the greatest, but one engineering design class had all the students file a patent (school paid for it) even if it was rejected. We need more practical education like that.

You're going to need some serious specifics OP, and cover all your alternative designs. You can't be vague. Like if you had metal as a material in mind, still say metal, wood, or plastic.

I struggled with pretty much every math subject when I was a kid, probably because I never paid attention in class or opened a book at home.
>>
I was 14 at the time and had little respect for math. Then when I tried teaching myself basic calc I stuff whilst in precalc, I realised how awesome the subject was and figured out that I only hated math because lower-level shit was boring repetitive crap.

"As a man who has devoted his whole life to the most clear headed science, to the study of matter, I can tell you as a result of my research about atoms this much: There is no matter as such. All matter originates and exists only by virtue of a force which brings the particle of an atom to vibration and holds this most minute solar system of the atom together. We must assume behind this force the existence of a conscious and intelligent mind. This mind is the matrix of all matter"

What does he mean by this?

The beginning of the statement is the utmost basics of quantum theory and his work. Then, IMO, he's stating that the same fundamental forces which give rise to our Universe created our sentient mind which perceives them -- leading to some deduction by Planck that matter only truly exists because we exist within matter to observe it.

"existence of a conscious and intelligent mind"
didn't he mean that god created that force?
