All you need to do is travel near the speed of light and time will slow down enough that it'll take a few minutes to travel years into the future so just do that OP

or breed humans and chimps to create hybrids which scientists do say is technically possible.

Millenial trips, nice.

You think worse experiments haven't and aren't being performed?

How about a real life allegory of cave?

The people on /sci/ can solve your piddly little calculus problems standing on their head.

james stewart's calculus is a good choice because it's made for self-learning.

https://www.amazon.com/Calculus-James-Stewart/dp/1285740629/ref=sr_1_1?s=books&ie=UTF8&qid=1472297369&sr=1-1&keywords=james+stewart+calculus

you can find all volumes in pdf online for free after some googling

surely there are more strict introductory calculus books out there like spivak, apostol and etc but unless you're looking forward to some unwanted mental masturbation there's really no need for them. it will depend on your goals.

[math]\sqrt{-1} [/math]

sqrt(1)=+/-1

Whatever the solution of
[math] \sqrt{x} = -1 [/math]
was, if would fulfill
[math] (\sqrt{x})^2 = (-1)^2 = 1 [/math]
and as long as we stick to [math] (\sqrt{x})^2 = x [/math],
this means the task was to find an object with
[math] x^2 = 1 [/math]

If we read 1 as the two-dimensional unit matrix
I = ((1,0), (0,1)),
then
i = ((0, -1), (1, 0))
does the trick.
In the field of matrices for the form
a·I+b·i
the equation
[math] x^2 = I [/math]
has a solution, namely
[math] x = i [/math]

Now to your question.
If we stick to + meaning a commutative operation and we want to extend the real numbers (a vector space over R), then a solution to
[math] \sqrt{x} = -1 [/math]
implies a solution to
[math] \sqrt{1+y} = -1 [/math]
for some y
but then
[math] 1+y = (-1)^2 = 1 [/math]
and
[math] y = 0 [/math]
IF there is a solution then it's
x = 1+y = 1+0 = 1

But if the square root ought to be a function (not related to values poping out of continuations alla Riemann), then we take [math] \sqrt{1} = +1 [/math]

Someone who tells you that is either bullshitting you or trying to sell you something. The fact is, no one can predict the future and whatever challenges may appear on the way. A specific cure for Parkinson's disease is extremely unlikely considering the damage is permanent for example. People who estimate this shit is so full of shit I'd flush them into the toilet like the turds that that they are.

Blindness and deafness can, depending on the type, already be cured to a degree. Not returning 20/20 vision or anything tho.

Immunotherapies are in nowadays against cancer. Let the body heal itself and all that.

But when we get regenerative therapies working, shit'll be cash.

Sounds like a great idea! Sulfur Oxide? Chlorine? Red Phosphorus (g)? So many options!

I had a dream last night where I was developing a compound that breaks down crude oil in sea water. I later woke up and realized I was still unemployed.

>>8300733

breaks down or flocculates ?

because they already have the latter

microbio undergrad here, I was thinking of maybe working with Pseudomonas aeruginosa. I want to create mutants that can help clean up oil spills more efficiently.

thoughts?

where does all the matter from the black holes go?

into a big bang

>>8300535
The big bang wasn't a black hole, so I can choose both.

>>8300535
gravity didn't exist during big bang

What an idiot! Pluto isnt a planet

Yes.

Its not so much something you have. Its a footprint and we are all stepping in the same space time.

Obviously.

Okay.

an equation that normally has no solution can be made to have a solution that is useful.
if u had mentioned infinite sums then that'd be a different story

>>8300377
All math is an invention, conceivable numbers included. That is kind of the point and why it inst a scientist. But it certainly doesn't make it useless.
