For the first two.

ALSO: No real center. Mass increases because it takes more energy to accelerate it 1m/s. Where a non-moving object of 1kg needs 1 newton an object moving at .99c needs many more newtons to accelerate it 1 m/s. This is without friction. Actual mass doesnt increase but inertial mass does.

Phys
1. Position as a function of acceleration with a starting velocity and position of 0
2. You cant know both the position and velocity of an electron because when you go to check its position you interact with the electron changing its velocity.
3. Relativistic mass was rejected by einstien and many scientists today in favor of relativistic momentum in its stead. It is basically saying that the amount of energy needed to increase the velocity of a piece of mass is dependent on its current relative velocity, and this function is based off of the mass increasing in size as velocity increases.

In laymans the sarcoplasmic reticulium...

Starting with a neuromuscular junction electrial signals travel across a muscle cell to a t-junction, which the signal then goes down. The signal tells a protein (not much is known about it) connected to a sarcoplasmic retic. to release all of its CA++ to allow muscles to contract. It then uses ATP to bring the calcium back in afterwards.

1 Proxima centauri
2 Our insignificance, we are on a speck of dust.
3 There is no such thing as a center

1 The endoplasmic reticulum has a smooth and a harsh portion, the sarco is the latter i think. It is full of polymerase enzymes i think. Fuck biology...
2 Input: O2, ADP, a simple sugar with 2 carbons.
Output: Adenosine triphosphate and CO2, and some other stuff
3 ?

1 O
2 14
3 Tritium

1. What is that retarded question? for acceleration with no initial speed i quess, x= x0t^2/2
2. Cannot know both position and momentum. Neither can we know energy and time due to special relativity. The uncertainities multiplied equal h bar/2
3. At high speed, a force applied to an object in direction of movement causes less acceleration than at lower speeds, due to relativity, just as if the mass in this direction was increased. It should not be called mass because it does not apply to an perpendicular force; instead, use F=ma gamma^3

Physics
1. what is this i'm not sure!
2. there's an inherent uncertainty between measuring position and momentum (hence velocity). the mroe accurate you can pinpoint your position, the less accurate you can know about momentum, and vice versa
3. mass gets higher as you go faster, seen from a stationary frame

Biofag reporting in:

1: Sarcoplasmic reticulum: Type of SER, or Smooth Endoplasmic Reticulum. This differs from Rough ER because rough has mitochondian on it's surface, smooth doesn't.
2: Krebs Cycle= How to energy through aerobic respiration. Acetyl coenzyme A+ 2Oxaloacetate= 4 Carbon Dioxide+ 6 Nicotinamide Adenine Dinucleotide(?)+ 2 flavin adenine dinucleotid+ 2 Adenosine triphosphate+ 2 Oxaloacetate
3: DNA helicase. (That was the hardest one as I learnt about it in 6th form, and haven't used it since. (I.E: First used it 3/4 years ago, haven't needed it again)

to be honest, with biology, once you know the basics then you basically conceptually understand pretty much everything in the entire field

once you know cell biology and understand basic chemical cycles... nothing after that is conceptually new. it's just learning more and more and more and more different versions of the same shit. different cycles, different proteins, blah blah blah.

A) Technically, it's e^(pi+2*pi*n), so it lies in real numbers. But I'm still not comfortable with this, since the question is formulated in complex numbers.
B) x^x*(1+ln(x))
C) I don't really understand what's the figure.
D) aleph 1
E) What?
F) Dunno
G) lim(1/n)=0
H) What you mean diagonalizes? Perhaps, you mean orthogonal matrix.
I) 0
J) Don't remember, it was a long time age.

Sort of, I agree that with the basics you're pretty much set, but they're only foundations, for example, the basics won't help if you're into zooology. Each different topic has a different se of foundations that need to be learnt, so they can be built upon.
The same goes for Chemistry and Physics.

> I don't really understand what's the figure.
f(r,@) = e^-r^2. what's the volume under the function over the whole plane?
> aleph 1
technically the cardinality of the continuum is not necessarily aleph 1, but ok.
E) What?
what's the highest degree of the polynomial whose roots can in general be written in terms of radicals
G) lim(1/n)=0
nope ;)
H) What you mean diagonalizes? Perhaps, you mean orthogonal matrix.
i mean Q where D = Q^-1HQ. and you were right.

same goes for chemistry i agree, when you've learned the fundamental stuff about the structure of the atom, orbitals, then how bonds work, etc., there's nothing much new to learn.

but in physics and math you find deep and novel new things at every level.

that's why i only really find the latter two interesting. chem and bio were fascinating when learning about the big fundamental pictures, but after that it's just learning more and more specific cases of the fundamental picture and i find that boring as hell.

1. What is the closest star (besides the sun) to earth?
> I was gonna say alpha centauri, then I scrolled down by accident, and saw that the answer is Proxima Centauri, so I'll go with that.
2. What is the significance of the "Pale Blue Dot" picture?
>It's the furthest away a picture of earth has ever been taken. And it's quite moving, seeing Earth all insignificant and tiny.
3. What is at the center of the universe?
>A supermassive black hole.
