I want to know more about dualism. Science based arguments for and against it, and /sci/'s thoughts on it.

Is the mind a product of biochemical processes of the material world or can it exist outside of perceived reality?

Can't you believe in dualism and still accept there is no soul or spiritual world and that conscienceness is merely the result of chemical reactions?

If fact you could use dualism to say there is only this and nothing.

154 IQ here. I basically see regular people as inferior beings. I don't look down upon them, I just pity them. Whenever I converse with people it's like talking to a mentally challenged person. Basically it's like going through life being a different species to everyone else. I don't even identify with regular humans due to their primitive intellect. Thus, I am not able to feel empathy for them. They are like ants to me.

This is the solution to a problem asking for the charge density ρ given the electric field E, using the equation ∇⋅E = ρ/ɛ.

Why is it a legal move to multiple before and after the operator? It changes the answer (of course) to something that can be simplified and actually makes sense, but I don't see why this is the correct way to do it.

>>8718173


Yeah.. I stared at it for a good 4~6 minutes and at first I wanted to argue linearity but that's such a bullshit reason. I can't tell why. If you don't multiply by it, then it clearly changes the answer, you can see it on the first term easily.

I believe I have just disproved Newton's third law.

If a a vehicle travelling 60 mph hits a bug, it will create a force that causes the bug to splatter on the windshield. How come that bug doesn't create an equal and opposite force that causes the car to explode?

Experiment you can try at home!!
1) place a ceramic plate on the floor
2) drop a super bouncy ball on the plate
3) observe results
4) drop a rock on the plate
5) observe the results

The kinetic energy of a cocking bug isn't anything compared to a multi-ton metal brick on wheels, you mongoloid. Apparently, you forgot the second law, where "force" is referring to acceleration times /mass/. I swear to God you're literally retarded.

I guess people generally use pauses/prosodic structure in a certain way to indicate the structure of formulae like these. The guy's name is Mike Phelan. I don't think he's published anything comprehensive but I found this abstract

What the hell is "space-time continuum" supposed to mean?

Obviously space and time are very different concepts. Sure space and time can affect each others very intimately, but space and time will remain fundamentally very very extremely distinct concepts.

Space is a collection of lowest energy density objects there is, to which every other object relates to.

Time is a tendency for things to change.

Stupid physicists.

Even if you're a troll, I'm falling for this and will explain it to you like you really don't know since all my friends who I wish I could speak about it are brainlets and don't care about it

Spacetime is the same thing. We use "space" and "time" as diferent things because are human concepts to make it easier, but in physics, it's the same. We live in a three dimensional space and one dimensional time, a 4D universe. They interact with each other. There could be another "worlds" where there is, like, three dimensional space and three dimensional time properties, but I hardly think it will ever be found evidences about it.

I have an interesting conundrum.

What is the absolute minimum amount of food you would need to feed a female sheep of average weight and height in order for said sheep to not starve if it also consumed all the feces it defecated? The last bit is the tricky part, figuring out how much nutritional benefit the sheep could extract from it.

Uroboros or sheep centipede.

I'd expect it would live longer if it didn't eat any of it's feces. Not a biologist though.

The majority of nutrients present in fresh food are lost after digestion. Only indigestible fibre remains

The repeat eating of already digested food will offer little to zero nutrition, so the eating of shit is moot

Your question reduces to "how little food can I feed a sheep before it dies?"

/fit/ here again.

I'm a thirld wolder so I want to make concrete weights because I'm from a poor shithole.

Can you guys give me the recomendations in terms of volume I need to make weight plates of 2kg, 5kg, 10kg and 20kg?

what would be the volume in cm3 of said weights assuming average mix of concrete and grava (sand).

also, what would be said volume in relation to cans, like how much big in liquid terms (gallons or liters) do the cans/bottles need to be.

Too retarded to do the conversion.

Many thanks for your help.
