In flat euclidean space, yes.
Post your proofs and shit on other's proofs.
Only rule: No QED = DON'T POST
Just got to the part of my linear algebra book (p.240 and beyond) where they finally define matrix multiplication as composition of linear maps and there are a bunch of short matrix algebra proofs as problems left for the reader. Enjoy my basic logic process.

Hey /sci/ just a quick one, was wondering if it's possible for the frequency of light to synchronise with a moving object so that the latter would appear to be moving still? i.e. a buzzsaw might appear as if the blades were unmoving??

I already have the solution because I looked it up, don't really understand the pattern though...

If the ans D. Then the bottom 2 shapes in columns 1 & 2 appear to be mirror/transform/reversal (reversal meaning concave to convex).

E
its rotating clockwise

it really is E.
but what's up with the other pictures then? where's the pattern there?

x^x = e^(log(x^x)) = e^(x·log(x))
=>
log(x) == 1/x
and now you gotta check the productlog

why don't you just see where x^x=e in a graph?

>Employing strictly the properties of the set of rational numbers listed above
What did mean by this?
How does one go about proving i - iii employing strictly the properties of the set of rational numbers listed above?

>>7806656
It might help if you post the properties that you cut off from the top of the page
>>
>>7806673
to do 1.(i):
ab+a(-b)
=a(b+(-b)) (by (v))
= a0 (by definition of additive inverses)
=a(0+0) (since 0 is additive inverse)
=a0+a0
in particular this implies a0=0 so a(-b)=-(ab)

Why do head hair grow without boundaries, and any other hair, eyebrows, eyelashes, pubic hair, hair on legs or arms only grew to a certain length and once you shave them they will grow back to their original length and not get any longer, unlike head hair which will grow and grow unbounded?

Because hair in certain areas are programmed to fall out at faster rates than the hair on your head or face
>>
>>7806589
So we just loose the hair before they can grow beyond certain length? It doesn't look as if it was the thing
>>
>>7806581
Because that is how God created us.

Have you read "The World is Flat"? According to the thesis there you could upload you r position (because GPS is cheap) and image of your position (because bandwidth is cheap) to the cloud (cheap, cheap cheap) and get two (two for the price of 1) Indians (cheap, did I mention cheap?) to review the imagery and then they upload walking instructions back to the cloud (cheap, cheap latency) where a server in the cloud validates the answers independently (because CaaS is cheaaaaaap) and then return to you with what to do next.
The book was very influential a few years back but with the financial collapse since Lehman Brothers the author has been less exuberant about it.

Short answer that's only slightly correct, but correct enough for you:
lateral forces.

same reason you can bend a clothes hanger by pressing it against a pillow.
The blade doesn't wear away, the edge just gets deformed and stops being as sharp.
