E = hf = hv/λ = hp/mλ = p^2/m ? Is that right? (non-relativistic)
332 posts and 54 images submitted.
>>
I thought it was p^2/2m.

I'm reading Babby Rudin and he says if m^2 =2, then we could write m = p/q where p and q are not both even. How does he know that? I'm in calc 2...is this book too advanced for me?
>>
>>8466564
Is that part of the proof that the square root of 2 is irrational?

He is probably just saying that for any number m, we can say m = p/q, where p and q are two other numbers to be determined, and you can make it so that they aren't both even.

For example, if m=5, then we could use p=15, q=3, p/q=15/3. There's never a situation where the only possible values for p and q are both even, because then you could simply divide p and q both by 2 until one isn't even, and the value m remains unchanged since you're dividing the numerator p and denominator q by the same value.

It's all very simple and pedantic, but these subtle properties are important later on in the proof.

Tump is going to initiate a new spacial age, and the objective is to reach Europa, one of the Jupiter's moons. Also he want to research new types of rocket technology and mine asteroids. Read the article is pretty interesting and I think is viable, also most space experts support Trump in this decision. And hopefully, China, India and Russia will get triggered and we will have a great space race.

Read up on the Double-Slit experiment

Basically, waves and particles are two manifestations of the same thing. Depending on the context, it may be more convenient to refer to them as one over the other.

Dumb spotted. "Two manifestations of the same thing." What a dumb.

Two different things can't be same thing, that's not how determinism works, you dumb.

How can we quantify consciousness using technological equipment?
14 posts and 1 images submitted.
>>
You can't. It's not generated by Matter. There is no Positivist way of measuring the difference between my Consciousness and yours or between a random Human's and an Ape's. Most people have stopped trying and are now pushing the idea that Consciousness "isn't real" instead. Which is ironically the ultimate concession since even the people claiming this will readily admit that this idea does nothing to "dispel" their own Consciousness.

Consciousness is the only thing that keeps going when you look away. An irony so perfect that it's almost Divine.
>>
You cannot quantify it as you cannot quantify a computer programm interacting with the user. Both are only bunch of electrons that are interpreted through either organic or inorganic reactions. The rest is just the start of gearing which depends on how the gearing is built.

>>8473621
Can't you quantify artificial intelligence? What's so difficult about translating it to binary and algorithms?

Most xenoestrogens come from plastics so try to avoid those.

that would be basically impossible to avoid.

only buy food in carboard boxes and paper bags I guess?

Yup. It's hard but hey, your ancestors made due. Hit up farmer's markets, make sure your tech is made from glass, ceramic and metal instead of plastic.

not really an answer is it? i want a mechanistic one.

why do we need locomotion? is locomotion the only thing a nervous system does?

I've never cried. Or felt sadness.
I felt a lot of anger and frustration at not getting stuff.
But sometimes I do feel a sort of "deep" OH. Awe like.
It happens nearly never but it's nice.
"Cold and austere beauty" kind of feel.
