Hmm, let me rephrase that, how much force do you think each tungsten rod would exert on the planet?

They are words that are only and exclusively useful when binary.

Nobody ought to give a shit what you "identify as". What matters is who can fertilize, and who can get fertilized.

The SRY gene is a social construct you fascist

Sex is a biological thing. It can change, theoretically, but odds are it doesn't for any one individual.
Gender is a social construct, it can change, it can be non-binary and while it is influenced by choice, it isn't wholly under the control of the individual.
That said, nobody ought to care about anyone else's gender, or rub their own gender in anyone's face. It's a non-issue and in most cases is simply used as a way to harvest attention from others.

What about 'sports smarts' like Wayne Gretzsky? Or is that still math since it's applied game theory?

no you fucking brainlet

no

Kinda.
I don't like using math without knowing why it works. But some people like to use math just as a tool, that's okay if you do it right.

>>8980630
Whole modern world functions like this.
Specializations allow it to exist.
If you wanted to learn how to make and operate everything around you, you would never do anything else.

What are other uses besides reusing it as hair? Something more practical

It can help clean up oil spills at a pretty impressive rate.

it's not a perfect clone, that'S impossible because there is homologous recombination during female meiosis (it creates novel combinations)
but it can come close to one, and this is called a back crossing

>>8981319
it can never be a perfect genetic clone because you lose one set of chromosomes when creating the kid you fuck. so the kid is haploid for your genes, you are diploid for your genes, you fuck, and again, half of the genes from both are lost, including potentially some of your material in the kid.

basically you couldnt accomplish a perfect clone (alleles exactly the same) through this, that's the point of genetic variation advantage of crossing over during meiosis

>>8981327
even with backcrossing, causing the exact allele distribution the father has would be statistically impossible, unless eventually a way is found that allows for chromosomes to segregate with a bias, and we obtain control of that mechanism, and apply it to every gene

What don't you get?

>>8981257
I'm getting most of it with practice.

The main thing making me stumble is stuff like
>You have a half-circle of charge distribution of radius r
>Its charge is positive in the second quadrant and negative in the first quadrant
>What is the net electric field on a point charge at (0,0)? At (2,0)? at (-3, 3)?
>What net forces result on a positive point charge? A negative point charge?

I can sketch the problem just fine. And I know how the particles react, but converting the sketches to calculus just fucks me.

The charged line, the angle, and the X and Y values all change as you move around the circle. But somehow the infinitesimal changes in theta, x, and y should all balance our, or something? And the changes in charge can be converted from, say, dQ into lamba dL? Where Q is the charge and L is the length of the semi-circle?

I get symmetry. That stuff's cool. I like ignoring half the problem because of canceled forces. And I can solve the integrals after they're constructed.

It's just the construction in the first place that gets me. It's not just in Physics, either. In all of my STEM classes, constructing integrals for anything more complex than "work required to drain a cylindrical tank" is hit-or-miss for me, indicating I conceptually don't get it.

But again, I'm not here for help on a specific problem. Rather, I'd like to think more like someone who KNOWS electrophysics.

In America? Yeah it'd be a safe bet if you have connections. Otherwise its just like any other CS degree.

Europe? Absolutely. The EU are getting their shit together and writing up some decent regulations regarding it, so it wont be long until every company with any kind of database needs the skills of an expert.

What about heat dissipation?

Doesn't most RTGs look like they are 90% radiator anyways?

>>8981172
The reactor was designed to operate more efficiently when outside of acceleration. It would operate at meltdown. The Neutron poisons kill the reaction before an acceleration causing it to cool with the thermocouple down to a solid.

>the series expansion of 1/(1+x^2) around 1 has a radius of convergence √2 because this is the distance between 1 and the function's nearest singularity (which is at i) when you view x as an element of the complex plane

>if two functions are holomorphic on a connected open set D and the functions are equal on a subset of D that has a limit point inside D, then the functions are equal on the entirety of D

>if f(1/n)=g(1/n) for all n then f=g everywhere

>the value of a holomorphic function at a point is completely determined by averaging the function's values around a random loop enclosing that point

According to the American Heart Association the heart beats an average of 100,000 times a day -- anywhere from 60 to 100 beats a minute -- which adds up to more than 2.5 billion beats by the time we turn 70-years-old.

it's muscle contractions

>Anyone with knowledge care to explain how it is possible for a heart to beat for a 100 years.

Teenagers always get this wrong. Do you even know what keeps it beating in the first place?

Read up on muscle function and neural signaling. The heart is just a fancy twisted muscle.

If we allow two parameters, we can parameterize the surface of the 3d solid by 1 parameter subgroup of trajectories and consider the second parameter to govern the dilation of this boundary (going from 0 to 1).
