Yes, obviously. Did you have a question?

I did not.

If there wasn't a universe, any discussion of time is pointless.

When did you realize that being infinite means being bordered by nothingness?
38 posts and 2 images submitted.
>>
>>8510720

Infinite numbers aren't bordered, that's the point.
>>
>>8510720
The answer is 16

Infinite is also equal to the number of times I fucked your mom OP. Without borders. i.e. she and I are still fucking.

why dont you ever see x-axis of imaginary plane and y-axis of imaginary plane?

and area of a circle radius i would be

A = pi*i^2 = -pi

Because it doesn't add any new information that way?

You're just taking R^2 and multiplying by -1. Good job.

Think of a comic book. The book's pages are flat, even if you rip them in half. When you turn the next page, you are essentially determining the time rate of each event. The universe is essentially a different slide each and every time a Planck Length passes (smallest unit of time). If it were curved, the universe would be "curved" inwards as if you were pushing on a trampoline from the bottom. Things would rush faster outwards and would appear as if they were moving faster than the center.

A three dimensional system can only have one axis of rotation this gives it a flat shape

can someone explain to me the difference between voltage and voltage drop, especially within the context of pic related
9 posts and 2 images submitted.
>>
>>8512087
Voltage is always in reference to something.

That pic appears to be voltage across a resistor, current thought a resistor, and power lost through a resistor, all with resitance R ohms.
>>
>>8512087
In more simple terms of>>8512090
Voltage drop is the loss of 'electric pressure' across an element of a circuit.
And Voltage is just the 'pressure' driving the electrons forward.
>>
>>8512090
Yeah I would say voltage is just voltage, the drop is what is measured across a component or even a long transmission line for example.

Are these creatures conclusive evidence for the theory of evolution (be it natural selection or otherwise)?

Still nobody can explain to me how cuckoo brood parasitism evolved.

Once you have done that then you have proved evolution once and for all

Can they mate with each other?
There is no proof that an offspring could not mate with it's ancestors or "cousins" in fact I can mate with any female human that is not sterile. (We're assuming that the human is not too old or too young for reproduction.)
>>
>>8512050
How could you not explain it? Mutationsort are the driver of evolution and mutations are random. With that in mind, what is the problem with this form of parasitic relationship ?

JS is for dumb designers and frontend noobs

looks pretty cool OP
JS probably isn't usually agent-orientated, and it might pay to learn/borrow some algorithms from elsewhere
have you learnt much js through it yet?

It's got a pretty derivative.

According to my calc 2 professor, it's because all of the other calc professors have an enormous hardon for it. In his words, "you're going to be seeing it a lot, so it's best to get comfortable with it now".

Hello Varg.

It's considered a science because it uses the scientific method.

So I was on a lecture the other day and someone talked about properties of cancer cells compared to regular cells. From what I understood, the problem with cancer is that
1. The cells grow in bunches and spread to unwanted places.
2. The cells don't stop splitting, making it harder to destroy them.

So, I had an idea at that time that I wanted to share with you guys:
Is it possible for scientists to biologicaly design cells that use the 2nd cancer property that I listed, but without doing the 1st? Can we make use of this to create limbs and internal organs that can self repair, given enough time?

Disclaimer: I browse this board mainly for math purposes, and have no more than basic level background in biology. So explanations to where and why am I wrong are also welcome.

theres a lot of work being done on that OP. google telomerase research. only thing is its damn hard to activate telomerase in non cancerous cells and non gametes.
