do I need to review high school algebra and trigo?

>>8632039
Oh ye you should review algebra and trig then.
Don't you do vectors in space in HS?

Very ambigious.

This pellets is red hot from the radiation. So there's that.

Wut? Who has been feeding you info?

>hot from the radiation
That's a pellet of plutonium, but at what point does plutonium begin to glow red from heat? It has a melting point of ~639C, so somewhere between that and room temperature, I suppose. Not very specific, but it seems there's not as much information about plutonium knocking around as there is about iron for some annoying reason.

>>8631564
No, not at all.

>>8631564
Calculus and Calculus-based DEs are not a field of mathematics, they are classes for engineers.

>>8631564
They are the most important for physics, I guess.

No. Nobody cares. Stop thinking about this shit.

Willng to trade

For a necklace to be symmetrical you can just make a string of seven unique beads and reflect six of them in a row and append them to the original seven. So you can have the middle of the thirteen beads be any of the sixteen kinds of bead. The next one can be one of twelve, since it can't be the same colour. The one after that can be one of twelve, and so on. (Cont.)

Scratch that entire previous post. What does it even mean to be symmetrical, you mean the bead types, or colour, or what? If it needs to have symmetrical colour on a closed necklace I don't think it is possible.

Theres 100 of subfields to any of those nowadays. And they overlap a lot. Just start some broad MSc and you will find out what you like doing the most on the way.

>Who do you think would win?
The same people who always win when two different groups come together.


The pornographers.

well such a being would be like a more developed version of a human

humans developed at a time with a rich unspoiled earth full of natural wealth and wonder. it is highly probably we will go extinct within the next few hundred, maybe thousand years or so. and new forms of intelligent life will likely evolve, and since the world won't be so full of resources for them, it may take them a lot longer to settle down and develop civilization, allowing them to develop more advanced, logical brains. so theoretically this could exist as some kind of futuristic post-human.

but in a competition the answer is the humans would win on a societal level because our high level of social tendency allows us to form highly complex, specialized, developed societies with pooled resources making huge advances on a collective basis. so we advance much faster, outbreed and overpower the weaker, more rational post-humans with the power of love and blah blah some hippie bullshit. but you get what im saying

Depends on the environment. The Vulcans would probably do better in a modern structured society with laws, money, and enough technology they don't need teamwork to do very basic things.

In hunter gatherer times they'd be fucked. Our emotions and ability to perform complex social interactions evolved to keep groups together. People don't last long alone in the wilderness.

Woah. I have that book on my bookshelf from undergrad a few years ago.

"The arrangement of thick myosin and thin actin filaments in the relaxed state is shown in the top diagram. In the presence of ATP and Ca2+, the myosin heads extending from the thick filaments walk toward the (+) ends of the thin filaments. Because the thin filaments are anchored at the Z disks (purple), movement of myosin pulls the actin filaments toward the center of the sarcomere, shortening its length in the contracted state, as shown in the bottom diagram."

Hopes that helps. kekekek.

It does, thanks man, the only reason i lack some confidence for this is because i bombed when we went over vocabulary.

>>8630139

Yeah, you are bringing back many memories of 6+ hour cram sessions. Good luck!

>>8630023
You have two different problems here.

1. Wavelength * frequency = c in all frames.

If one changes, the other must adjust so that c is maintained. Otherwise, c would not be constant in all frames which is false.

2. If changing regions causes a change in length or time, by SR you can find exactly what that is and find the corresponding wavelength or frequency. This gives you your new momentum.

Additionally, a change like this could be interpreted as a change in reference frames. This necessarily means a force is involved. The energy difference between the new and old states will be precisely whats put in / taken out by the force.

The question as you ask now is actually nonsense. Momentum doesn't need to be conserved if you're just measuring a system under two different conditions. Is only when those systems/conditions are related that you need to see conservation.

>>8630023
The frequency of the photon tells you its energy--it doesn't change in different regions in space (modulo some "gravitational redshift," but this is, for a technical reason, a moot point). So just assume frequency is constant and describes your photon. Now, as it travels through a medium with index of refraction n, it will have an effective velocity v = c/n and an apparent wavelength' = wavelength / n. Both energy and momentum will be conserved (as they have to be). Notice that for a photon, w = ck (in vac) and so the phase and group velocity are the same. Notice also that the velocity of light is independent of wavelength.

>>8630181
This is completely incorrect, anon. 1) Frequency of light doesn't change to match--it's apparent wavelength does. And apparent velocity of light does change. You're reasoning is true for different photons, where a different f describes a completely different photon.

More importantly, you should go take another look at special relativity. First, changing regions the particle is in has nothing explicit to do with changing reference frame. And a change of reference frames has nothing to do with a force!!!! A force CHANGES the dynamics of a particle--SR says that there is no fundamental difference between a guy moving at a velocity v1 and a guy moving at velocity v2. But a guy who feels a force? Completely different and not at all related to SR reference frames. And note the main assumption that gets you to SR--the velocity of light (in vacuum) is constant, or c. This means there is no rest frame for the photon. Every reference frame observes a photon that is moving at c.

And momentum/energy are always conserved in SR (though not necessarily separately); you just need to work with the combination (i.e. the momentum 4-vector)

study molecular biology and enter the biotech industry is the closest you will get right now

Sales,marketing, finance, and law.

Most science is done by impoverished and underpaid people begging for money and publication, or BH impoverished and NOT PAID students.

Science is a shit field to get into when EVERYONE that's anyone takes advantage of their property and rights to exploit the situation for their own benefit at humanities expense.

Get yourself some solid education based on a market revolving around speculation and false value.

Then maybe you'll be lucky enough to tongue a CEOs asshole clean for a six figure income.

Yes is is. What do we do to fix public education/bring education to the private sector?

But people already study agricultural science and philosophy majors already pump gas.
