Shut up.

Right answer is true. Are you retarded OP?

Two are red. (2 == 1) = false.

oy fucker im talkin about chemistry here, im not lookin for some cosmonot to tell me about his trip. I want to talk about synthysis of psychs fucker

>Invivo Therepautics
This is a company that is looking to use what they call a "Neural Spinal Scaffold" to bioengineer neural tissue via Neural Stem Cells that would be inlaid into the spinal scaffold. A 3D bandaid if you will, go in, cut the damage out, apply the 'bandaid' with stem cells giving the nerves framework to cling to. It is compromised of what they call 90% air so as to allow it to be absorbed by the body naturally once the nerves have regenerated. Clinical tests have been done on acute and chronic with some improvement WITHOUT the preloaded Neural Stem Cells this company has in their hands.

>Stemcells Inc.
This is a company that is looking to transplant CNS-derived stem cells to create multi-potent, tissue-derived “adult” stem cells that are directly transplantable into the brain, spinal cord or eye without the need for immunnosuppresive drugs as the cells are created from your own system. From what I can understand the cells are injected into the spinal cord where your injury is and accompanied by peptides to allow the axons to grow through the glial scar that blocks chemical signals.

>Olfactory ensheathing Bulb
This is more a less an approach that has been barely broached but shows huge promise, by using cells cultured from the olafactory ensheathing bulb within your brain as they are the only cell able to continuously regrow throughout your lifetime. They are also perfect for recoating the axons in myelin a fatty substance that gets damaged during SCI, which allows electrical signals to be transmitted swifty.
I could go on with more things ive read about, but the end point is, none of these true clinical trials have yielded any side affects, and if they coupled 3 or 4 or 5 of these specialized cells with Invivos spinal scaffold.. hey we'd be laughing! I mean wouldnt we? So what do you all think and know? id very much like to discuss it.

I haven't done physics in a while but I think it's because the center of mass of the system {guy+raft} doesn't move

>>7669693
Also, I don't think the movement of the raft depends on the mass of the guy standing on it, it just moves the same amount in the opposite direction

It's easier to reason about this if you think about a skateboard.

But your assessment seems correct to me.

1 is entirely subjective; any equation can sum it and the same applys vice versa
In my unpublished studies there's 16 to 34 to 41 types of 1 depending on what space scope you're using

The real kicker is in 2=/=1.9999...9888....98.....{.9898989.}.... , and up to 10 where 9.9999....90000.....

after that it's just silly....

....No such this as irrational ;)

Computer engineering is just some EE classes + some CS classes AKA useless

Why would you choose anything that is not plain Physics?

>>7669525
because we want jobs

>>7669496
Don't want to get hooked on nicotine, and prefer not to inhale polonium etc. And I grew up around people who smoked.

I don't have an addictive personality, but I get attached to drugs easily. Stimulants especially. So I'll stick to caffeine and cocoa beans.

>stimulants
>make you smart
Choose one

Too expensive and addictive.

whats the potential of violate rays?

shorter wave length = more info on disc
r-right?

>Or is society just slowly moving away from disk all together so things are now all digital since internet access is pretty abundant?

This. Why would I want to buy a disk when I can watch something and then move on with my life instead of having it for a long time on a shelf? Books aren't a good comparison since they have great re-readability potential while you can only watch your favorite a movie for a few times a month maybe.

Your image distinguishes between input and output, you should too.

>>7669375
I'm not sure where you need the distinction made, but I'll try... The "prime mover," or the first thing that ever happened in this universe, would have to resemble the right half of the image. Just some output happening on its own, with no input. This universe is not capable of that, as far as we know, right?

>>7669367
the unmoved mover moves without being moved.
aristotle mentions the analogy of someone being loved. the loved one moves the loving one without being moved himself. he (or it) so to speak can't be causal. he just is.

>>7669342
Just review the dynamic sections in your heat transfer textbook. You're looking for the heat transfer PDE in cylindrical coordinates. In 1.a set all differentials with respect to time equal to zero.

This problem is too textbook tier for an exam imo. I'm assuming your writing closed book then? Your prof is a fag.

JUST

>>7669366
What textbook are you using?

>>7669247
No, it's hypothesis at this point, and not testable so far.

>>7669257
lol so its not real? Have they proven it?

>>7669247
>So let's get this straight. Are parallel universe/ multiverse/ alternate realities/ string theory or whatever you call it really real? By real I mean scientifically proven and is real in the sense that it actually exists.
Not scientifically proven, might be real in the "actually exists" sense since it's not disproved.

>I want to know if there could really be an infinite number of realities in an infinite number of universes where every possible scenario to every possible situation is happening all at once and everything that ever was is or could be or will be every possible solution or outcome or path of way of movement is possible and exists in a universe that is running exactly parallel to the one we are in right now.
That sounds retarded tbqh senpai. Even if there were parallel universes there's no reason to think there would or could be an infinite number of them or that every possibility exists in one.

I want to live longer, so I can help others longer.

What articles have you seen claiming we've discovered immortality? I'd be more interested in those.

>>7669259
Well, they weren't the kind of websites to use the words "immortality." More like they were calling this new drug "like the fountain of youth."

Just googling "anti-aging drug mice" and some of the first few articles mention it.

I'm paying extra attention to this drug because, well, I really, really want to live until the heat death of the universe.

Moving the equipment and rocket to the top of a mountain is harder than just shooting the rocket to that height.

>>7669216
Because atmosphere isn't the biggest issue, not by a long shot. Long story short, launching at the equator like the yuros is the best you can do as far as location is concerned.

>>7669225
What about tall mountains near the equator?

Look at equations like [math]e^{i \tau } -1=0[/math]

when you'll see the proof for 0.999... = 1

Feynman's IQ was 126 or 125 I think, not that impossible.

Earning a physics PhD really isn't all that difficult. It's not a standardized degree, I'm sure you can even buy it legally somewhere.
