good point.

>>8003441
i tried to find a way this makes sense but i couldnt find it.

even in a uniform expansion of everything (stellar) the speedlimit is violated.

>Believe that someone is going to answer that

Can you put this in the form of a frog meme?

>Why in quantum mechanics we continue using integral if the energy is quantized? I mean, the assumption of continuous now is invalid

Because of what is called the dual nature of elementary particle behavior. They exhibit both
discreet and wave properties. Waves tend to be "continuous".

show me how to write an arbitrary vector in [math]\mathbb{R}^3[/math] in terms of a scalar multiplied by the 69 vector and I'll give you $100000000000000000000000000000000

>>8004110
[1, 1, 1] is an arbitrary vector

[69, 69, 69] / 69 = [1, 1, 1]

Can you set up a coefficient matrix to prove this?

Here's your problem, at least play some good games

not OP, what is good game ?

>> ion propulsion
works today
>> solar sails
Nips did it.
>>quantum teleportation play a role
a very very iffy maybe and not in the way you'd think. There is a hypothesis that it is possible to quantum teleport energy, but you have to use classical communication to do it. And if you have classical communication, then you might as well just use it directly. IE instead of using lasers to perform some weird quantum voodoo, just go laser --> ion engine power.


Barring fucking antimatter, fusion propulsion is probably the best way to get around the solar system.

There is no future in space travel if you mean sending live humans to other star systems

If it was possible to send biological organisms faster than light to other systems we would have been visited dozens of times by now
There would be at least some evidence

>>8003056
What's wrong with it? A theory is a guess with varying degrees of evidence towards that guess. Gravity and evolution have a lot of evidence, my cats are aliens theory doesn't.

>>8003068
Lol,no. A theory is a fucking fact that has been proved mathematically. That's literally the definition of it, but fucking reatards walking around think it means the layman version of a guess

>>8003068
I'm referring to scientific theories. My bad I should have specified

>>8001042
You are doing it all wrong. Mathematics doesn't work with examples.

Let me tell you as I am majoring in mathematics so I think I have a better clue than you do.

Everyday professors come and draw shit on the board while they talk. I have my notebook with me but unlike my peers, I don't copy every single thing the professors say and draw.

I only pay attention to and copy: definitions, notation, axioms and theorems*

*I don't always copy the proof. I usually try to prove it myself and if I can't then I let it be and just copy what the theorem states, as I pay attention to the professor doing the proof, accepting my inferiority to him, as he can prove it but I can't.

I never, EVER copy examples, or pay attention to them. Lately I've been getting tired of this because as we dive deeper into set theory and other pure fields of mathematics, the professors feel the need to give like 5 examples of every concept they introduce because there is always the moron who won't get it in a million years. Fortunately this is the kind of degree where half the people fail by the end of the first year so next year only average and smart people will remain so this bullshit will stop.

Anyways, to sum it up. If you want to git gud at math then read and if you want memorize definitions, notation, axioms and theorems (lemmas and corollaries too, whatever, same shit).

You have to read them over and over until you internalize it. You have to feel what the theorem states in your heart.

When you have a true understanding of the core concepts, then you won't need examples because you will be able to work out everything yourself.

>DEFINITIONS
>NOTATION
>AXIOMS
>THEOREMS

>>8001059
That is a very interesting point. I was never good at math when I was a kid (actually, I fucked up pretty bad), but now I've found a huge interest in it. I just have the constant feeling that I'm not good enough because I don't get everything immediately. But, as you say, that is probably the wrong approach.

Thank you kind anon.

>>8001059
I'm the same way with examples, but you should never let the proof take a back seat to memorized theorems.
Understanding why a theorem was proved in a certain way is extremely difficult and eye opening, in most cases you will never figure it out on your own at first, but by following the methods used to do proofs you can internalize the methods and begin to apply them yourself.
Also:
Congratz op you will never make a first rate mathematician, go kill yourself

here's a less shitty pic

>>8002768
start with substitution y = x+1
x^y = y^x
ln(x^y) = ln(y^x)
y*ln(x) = x*ln(y)
y/x = ln(y)/ln(x)
Now, you cry.

exp((x+1)ln(x))=exp(xln(x+1))
=>(x+1)ln(x)=xln(x+1)
it's easy after that

>>7999944
Holy shit this had better be bait.

>>7999944
I'm getting 2 + 2/n - 8/n^3. Taking the limits to infinity, I get the limit = 2. I don't think that's right?

>>7999944
Seriously? No offense.

>Science can't even explain why we have gravity
Asking "why only makes sense if the universe has a" mind" of its own.
>I believe
K then
>Art
Well, there is some explanation as to why we prefer certain patterns, shapes and shades but it is still a young field. A Japanese A.I. managed to write a book on its own that passed to the final of some literary competition.

>>8004125
Art can never be prescribed to a science. Sure humans may prefer certain "shades and patterns", but that is meaningless as far as art goes. Explain why I find certain things beautiful, why certain things touch me: "Well you see, your right celebrum fires to the nervous chord and chemical react to give you a feeling". No. Humans are conscious being with free will, I don't care what we are made of, it's the whole bundle that counts.

>>8004135
I like vaginas because my free will told me they are beautiful.

energy and matter that we cannot directly detect but we can detect indirectly.

A meme created by Astrophysicists to hide the fact that they actually know fuck all about the Universe.

>>8003888

Or in other words, GOD

Off target effects is basically what called for the moratorium. The Chinese team was over-eager and rushed to embryo modification on a technology that was super inaccurate.

We still really haven't solved this inaccuracy problem so chill.

Also there is hella redundancy in biological systems so a simples control x + control v might not work here.

SUPERHUMAN WHEN?

what field can do this?

i want to breed humans have optimal traits for all kinds of sports, train them and have them win everything and bring my country and "coaching" to glory.

>ideal leg length + all high power fast twitch fibers + injury resistance + psychological genes to make them love to train and recover well= amazing sprinters
>breed man to have short arms and femurs, high test, high gH (huge joints), lots of fast twitch muscles, he'll set world records in powerlifting

IT GOES ON AND ON

>>8003798
>until the full implications
What the fuck does that even mean? It really sounds like a "I better cover my ass here" kind of statement.

How can I visually determine whether a 2D waifu has a cunt?

If there's net clockwise or counter clockwise motion. Patterns 1 and 3 have curl.

By looking at it.
