That's fine my brother. Just remember that the 10% you do remember should include:
>All the basics of your field in general. In math, this would be elementary identities in geometry, algebra, combinatorics, set theory and logic.
>All the basic ideas of all the courses you took, such that if you ever reread a textbook you already know the gist of the subject and can relearn it quickly
>All about your specialization
If you remember those 3 parts of your education then you will be fine.

Guys, I hate to be the dickhead here, but is it possible genetically speaking to be born with both a vagina and a penis?
My mate's girlfriend is being a tard and I need confirming scientific proof that it's not physically feasible.

>I need confirming scientific proof that it's not physically feasible.
Why would you assume that? Yes, it is possible and it has happened, just fucking google it.
>>9129498
genetics have nothing to do with it, but demi-hermaphroditism exists.
The equipment is not functional and not even fully formed, though.

So, here's a dumb question. The eclipse just happened, many people were disappointed, didn't get that dark.
Do eclipses ever get really dark? I thought about it a bit, and if this was a total eclipse or whatever, doesn't seem like it. The sun is much further out than the moon, and much larger than the moon. Even if the moon enacts a "total eclipse", the sun must be shining around it, right? There's no way it can block it all and make it legitimately dark.
Eclipses can't actually get dark, can they?
>>9129425
Nobody said the entire Earth is cast into the Moon's shadow, just that the Moon's shadow moves across the Earth. If you're under the path of totality, where the darkest part of the Moon's shadow will pass directly over you, then it will get pretty dark around you. However, the light scattered from the Earth's atmosphere around the shadow of the Moon will still reach you, resulting in non-total darkness.
Here's what the Moon's shadow on Earth looks like from space (too big to post here, remove the space) http://mediad.public broadcasting.net/p/shared/npr/201603/470091400.jpeg
You still see sunlight all around you from the areas not covered in darkness, and the corona itself also provides illumination. It's really more like a late twilight than the dark of night, when you're in Earth's shadow.
Even without totality, having a good coverage of the sun results in a weird dimming and desaturation of broad daylight, like you're wearing tinted glasses or are going blind.
I was in the path of totality. It was mind blowing. Kinda twilight but could see Venis, I was a little worried about the sun coming back. Damn it did.

but isnt absence a boundary in itself?
Can anyone out here explain dark energy and dark matter to me?
Is there a chance dark matter is not an object but simply irregularities on the surface of the universe itself similar to mountains and valleys on earth and these irregularities, indents and whatnot are what causes the gravitational anomalies?
Maybe the universe surface just isnt smooth and has occasional valleys and channels
A deficiency in the cosmological model.
>>9129165
Nobody knows what dark matter is, but its existence is inferred from the motion of matter observed in space. Rotating or merging galaxies behave as though they have more mass than they should do based on what can be seen by telescopes, for example. The matter also doesn't block light coming from behind where it should be, so it can't be low-temperature objects like asteroids or interstellar planets - it doesn't interact electromagnetically at all, hence 'dark' matter. It also causes gravitational lensing, which the bending of light by a mass. There are numerous theories attempting to explain these anomalies without dark matter, but so far 'there just being a bunch of matter there that doesn't interact with light' produces predictions that most closely match what's observed. It also wouldn't be nearly the strangest thing in physics.
Dark energy is more complicated to understand, but essentially space that's mostly empty and flat (far away from the gravity of objects with mass) is expanding, and that expansion seems to be accelerating - this can be likened to empty space having a particular energy density.
Both of these things are areas of active research, both theoretical and experimental. Only time will tell what the truth really is.
>>9130553
It's possible we will never understand because we can't see passed the beginning of what we call time.
Think about a civilisation that arises somewhere in the universe at a time when all galaxies have drifted apart to the extent they can no longer be observed.
They'll discover realitiviy and quantum physics and all the same laws as us, yet their 'correct' picture of the universe will be different to ours. A single galaxy alone in the universe.
Falsifiable science will produce the wrong conclusions.
If pure mathematicians are so smart, then why are they never able to do anything useful?
They are able, they just don't want to.

Define "useful". Mathematicians are more than capable of acting as actuaries, accountants, or engineers.
I have a theoretical type question.
If a person with Parkinson's disease drives over a road that is ridden with pothole, does the shaking caused by driving over the potholes cancel out the shaking caused by the Parkinson's, creating an equilibrium, akin to how two waves can cancel each other out, or do the potholes only make the Parkinson's more severe?
>>9128829
Why would you even think that the potholes would be in sync with their tremors? Of course they would make it more sever.
>>9128856
>Why would you even think that the potholes would be in sync with their tremors?
>Of course they would make it more sever.
Welllll.....
Mixing two random sets of tremors should result in some instances where the two cancel each other out, and some where they amplify.
I'm pretty sure that makes the overall result more chaotic.
Any white noise has a certain amount of "smoothness", mixing two white noise sources should reduce the smoothness???

If that's how it is, then I'm not even gonna talk to her or ask questions if she's gonna be that much of a bitch. Is this a good idea to just ignore her? I came from a Master's lab without a "lab manager" so the concept is totally foreign to me anyway. Is she threatened by me? Is me being the younger, more advanced in their career student making her insecure and feel the need to prove "hurr durr I am smert I have da authority"? What do I do? Everyone else I've ever interacted with in grad school has been cool.
Yes, ignore her and make her feel like it's a privilege granted to her by you when you interact with her.

if fluids are in-compressible, how can water be kept under pressure? Wouldn't any container you tried to fill with more water than its available volume just explode?
Did my physics lecturer lie to me and water is actually compressible to an extent or what?
clearly didnt do homework
>>9128692
Newtonian Fluids are incompressible. There no Newtonian fluids though.
>what is pressure
Imagine a column of water 1m tall and one 100m tall, neither is flowing water, which has more pressure? How are you keeping this pressur? The static condition just means the pipe material hasnt' burst and pressure is constant.
>>9128692
The force of pressure is just the force being applied to the water, transmitted through the water. Water is (for the most part) incompressible. If you push on the water in one end of the pipe that "push" is transmitted as force in psi/bar along all surfaces of said pipe. There is not more water filling a smaller space. If i stand on a pistion filled with water the pressure increases but the piston doesnt really move.
Is there a way to represent a turn based game, with a finite, discrete number of moves, as a graph?
Or what other forms of analysis can you use?
Let's use a mini version of the connect 4 board as an example. Say it is 3 columns by 5 rows, rules are that each player can pick x:{1,2,3} and that assigns them the coordinate (x,y) where y is the minimum y:{1,...,5} such that (x,y) does not already exist (just think about regular connect 4 rules if that confused you, the pieces stack on each other).
I enjoy turn based games, but I don't know a good way to analyze decision trees for them.
>>9128576
>>9128524
yes, in your example each move can simply described by the x-coordinate.
So a game can be described as a tuple (x1,x2,x3,x4,x5,x6,x7,...,xn) where the first player choses the odd components and the second player the even components.
A condition for admissible sequences is that the number of entries for each x is at most 5.
So you can describe all possible moves from a given sequence by adding a component say x(n+1) and assigning it any possible value.

CRTs use an electromagnetic coil to focus their beam, can the same be done to focus a beam of microwaves? If so what is the best coil type to focus the beam from a magnetron + parabolic antenna?
that doesn't seem safe
The US army has at least one type of directed microwave emitter. Whether its done with magnetism or not I dont know, but it is possible to direct microwaves
