>If B then C, thus if (A and B) then C
Why the fuck can;t I wrap my mind around this? Can anyone do a proof?
(A and B) then B
B then C
>>8390509
How is (A and B) then B logical?
>>8390522
Maybe I'm just dumb but let me give this a shot:
(A and B) is the intersection between A and B so it is a subset of both A and B. So anything in (A and B) is also in B. So we can say if B then C, thus if subset(B) then C as an equivalent expression
Stephen Hawking says that the universe can spontaneously create itself out of nothing. I've been thinking about this a lot lately, but I haven't been able to talk about it much with others. I remember someone else saying something along the lines of, if you put together all the matter, energy, dark matter, dark energy - all the stuff and anti-stuff - in the universe, you get a zero sum. If we can apply Occam's Razor to the question, why is there something instead of nothing, it seems like the simplest answer is that something, everything, is technically nothing.
What do you think? Is there evidence to expand on or contradict this?
>>8390463
It's not Hawking speaking, it's his chair.
Case dismissed.
You can either zero sum or use CHIM

What is the fear of a scientist? (or fears)
Many people may be afraid of something silly things when talking about them, for example: The end of the world, the control of governments and other conspiracy theories.
One thing that has given me fear is the decay of false vacuum, it is something that will occur in billions of years (this would occur if there is no physical more than the standard model) I will not be a witness to this event but still scare me (I have no idea why, but I think I have an existential fear with exotic deaths)
Returning to my initial question: What is the fear of a scientist? (or fears).
fear of unemployment

OP here. I expected a similar response.

I've found the lower scaling limit to the characterization of any n-dimensional black-box problem. I've decided not to publish this proof to preserve everyone's sanity, hopes and dreams.
My fear is that future generations will find this, see how bad it is and kill themselves.
>brb, killing myself
That is indistinguishable from what we are experiencing right now?

Depends what you put in your will.
If you chose cremation they will bake you in a oven until you are a pile of dust.
If you chose burial they will put you in a box in the ground.
Make sure you are fully dead because neither of these are fun for the living.

Im going to cremation your mom
So i know the mass is irrelevant i was going to use the equation 2(a-4*9.8)(5100)=Vf^2 but i dont know what the final velocity would be
could i replace Vf^2 with (at)^2 and solve for a = (a-4*9.8) and t=20?
You could solve it graphically by making plots of altitude, velocity, and acceleration.
>>8390183
against what? time? i half no idea how to solve it graphically though i heard you can do that and then just integrate to find the area under the curve, not sure if thats what youre referring to
If you eat something your body can't digest, will you be full forever?
>>8390158
No, you'll just shit out undigested food. Have you seriously never done this before?
>>8390158
WORLD HUNGER SOLVED
>>8390158
The problem is not the fact that your stomach feels empty, the problem is that your body would still be releasing the hormones it would normally release if your stomach was empty, even while being full of the inert substance.
For example, if you drink so much water you can't hold any more, but don't eat all day, your body will still release the hormones it generally would when it was low on glucose. So really all you'd accomplish is having to eat many small portions to become satisfied.
There might be an argument made that you'll feel nauseous after a small amount of food, but all that will do is make you return once you digest that small amount and your body still needs nutrients.

Post the best visualized math that you have. I'm trying to save a friend. She says math is hard because she can't visualized it (she is more of an artist) I have tried to expose her to the beauty of math and it seemed to be working until now.
Any advice into how do I make her interested in math again? Or at least appreciate math without forcing her? She has said math its really amazing and interesting but recently she has been loosing faith. The way I try exposing her was showing her equations that graph hearts or math tricks like Gauss' sum n(n+1)/2 that would make her interested. Maybe she just acted interested because I was really passionate about it but who knows.

Anyone care to give me a definition of entropy that is simpler than wikipidia?
>>8389835
Entropy is the amount of information needed to pick out a particular state a system could be in.
There is only one way to be a perfect crystal at absolute zero - only one pattern in which its atoms could be arranged at any given time.
But there are many, many different possible patterns if you vaporize it and turn it into a hot, jumbled gas with atoms whizzing all over the place.
There is only one way for a room to be clean and well-organized, but many ways for it to be messy.
>>8389835

>>8389835
Write the shortest possible solution to "2+2". It's 4, a single number, something incredibly low in entropy (1 bit). You either executed the equation or didn't, two states, representable by 1 and 0.
Now, you add the possibility for a random variable. The first one can be a random from 1 to 10, making the room for possible answers range from [1+2 = 3] to [10+2 = 12], or 10 different states.
What you just did is increase the entropy of the information of that function, which now has to be represented by 0 if not executed, and additional bits for the 10 values:
>1+2 = "01", 2+2 = "10", 3+2 = "11", 4+2 = "100", 5+2 = "101" and so on.
We say that there is an increase in entropy because the randomized integer allows us to have 10 different values, which need to be accounted for by 10 different combinations of bits in a binary system.
If you increased the random range of the left one to 1 to 100, to transmit that information to someone else, you would need a translator on their end that would decode every single bit combination from 1 to 100, or "01" to "1100100". That's a lot of possible information packets you can receive, therefor, high in entropy compared to the single deterministic 2+2=4 in the beginning.
That's as easy as I can go, but don't worry that you don't quite understand what it is right now, you will sooner or later. A lot of people struggle with it. Keep reading stuff about it and you'll eventually realize what it's supposed to mean
Can someone explain this to me? How are the angles of the sunbeams opposing each other so completely? Wouldn't that put the sun very close to the earth? If the sun is millions of miles away I would expect the rays to be nearly parallel.
>>8389781
bad bait, but its because the clouds allow the sunlight in in that direction. also sage
i too want to know this
suspect it maybe a break in another layer of cloud higher up creating a bright spot where you would expect it to be fro the rays
>>8389781
The sunbeams are parallel. Of course, from your perspective they don't seem like they are.
So are black holes a 3D sphere thats super dense. Or are they a 4D hole that does not make sense in our 3D universe?
Black holes are the result of what happens when a star's gravity is so powerful that it outweighs the star itself.
As a result it collapses leaving behind an invisible sphere of death.
It fades away very quickly right after destroying every physical thing that gets in contact with it.
It's 3D and tears at the fabric of space.
>>8389343
They don't actually exist so you can make up any bullshit you like about them.
What's preventing there being a super dense star inside the event horizon instead of a singularity?
If every race of human was blended together, what would the result be? In terms of skin color and facial features?

If force is equal to mass times the rate of acceleration, yet photons have no mass, how is it possible that we can use photons to move objects like the theorized "light sail?"
I can only speculate that photons have the smallest amount of mass possible, thus travel the fastest speed possible and we equate these as 0 in computing where 0 can act as the very first possible number, or nothingness.
>>8389086
Energy and momentum.
>>8389086
Massless photons don't really work without SRT.

It's not.
