To gain intuition for curl, just curl up in a ball and cry like the pathetic mother fucked you are

Or go to khan Academy

Curl is how much the field looks like a whirlpool. Divergence is how much it looks like a fountain.

This is sci, not philosophy. Sci only cares of the model works and predicts things. Metaphysics is a branch of philosophy that is basically untestable.While metaphysics is semi-import, particularly to early physics, most 'metaphysics' of our time has to to with attempting to map mathematical assertions into the quantum world.

I honestly don't understand... I didn't do anything... I just did my research and showed up to the meetings. I have a 2.5 GPA.

The catch is you'd be working with an illiterate.
Is he indian, OP? Don't ever work with indians.

look at what the drop in oil prices has done to the world economy and tell me free energy is still a good idea

It's pure bullshit. No scientific evidence or even theoretical explanation is given for why this magnetic field should replace the one that actually describes how we see magnets work and are described completely by Maxwell's electrodynamics. He just shows a bunch of pretty pictures. Don't come here to post youtube crackpottery without doing some basic wikipedia research.

>>7803412
It turns out that basing your entire economy on oil is retarded.

Sure is, OP - I myself am a time traveler from the year 1967 and let me tell you, things sure have changed a lot since then!

Yea you're doing it right now

Silicon dioxide + sulphur + the heat of a thousand suns = still doesn't burn
I'm calling hax on your sulphur thermite

>>7802702
forgot to include aluminium

>>7802704
Why did you use any sulphur

Just avert your gaze every half hour or so. Try not to sit in the dark

I started using f.lux a while back, don't know if it's really all that effective but I noticed way less blood-shot eyes since I started using it.

>>7802498
Also nearsightedness is negatively correlated to the time spent outside.
So spent some time going outside and looking at far away object to avoid fucking up your eyes. Look out of the window every half hour or so

>>7802461
Lol, enthusiastic. Well, if you're ahead of your peers then I suppose I understand your current opinion on your status. Anyway, if you know what a derivative is and don't want the theory, then you're fine. If you want the theory, you should probably understand some set theory, a very small bit of topology, and limits.

start here for some background

Read Calculus by Apostol.
You need no previous math knowledge.

I am incharge of 7 junior engineers who pretty much can only build basic shit, 3 highly competent "old hands" who can do anything, 2 electrical engineers and one aerospace engineer.

We are building a small one-seater car.

This was my organisational plan so far, I figure I will only have to keep in regular contact with the "Heads" of the various project parts, each of whom are very competent. Does it seem ok?

You're not there to micromanage them.

Especially since you admit you are underqualified, you're not really in a position to second guess them and you already understand that they are better engineers than you. That shouldn't stop you from floating ideas out there, but don't be the PHB who suggests things beyond the realm of possibility or deadlines.

You're there to remove any impediments the engineers face when completing the project. You do all the bullshit bureaucratic administrative stuff so the engineers can focus on what matters. Do the bullshit paperwork or spend hours on the phone with your supplier getting that critical part on order for a prototype. No offense but good managers are pretty much glorified assistants to the whole team as well as advocates/organizers.

>>7802111

Right.

How far should I be willing to go vis a vis making people meet boundaries, checking that progress is being made, etc

What is [math] \mathcal{M}_2(\mathbb{R}) [/math]?
Is it the ring of [math]2 \times 2[/math] matrices with real entries or what?

Viruses are not alive because, quite simply, they do not have any metabolism. They are just DNA wrapped up in protein coating. They're closer to machines than living things.

>>7801160
Labels like living and nonliving only exist for humans to easily classify information. Most things when scrutinized have gray areas in their definition or classification. When people describe viruses as nonliving, they are saying that viruses do not have all of the typical requirements of a living creature, not that viruses aren't actually alive. Obviously a virus is not nonliving the same way a rock is nonliving.

>>7801160
>They don't use it on their own, but the host cell needs energy for the virus replication to complete

That's because the virus isn't reproducing. The cell produces the virus. To be classified as 'living', it must be able to reproduce itself, not to simply be produced by external factors.

>They don't use it on their own, but the host cell needs energy for the virus replication to complete

Aside from the last point, that's like saying pennies are alive because it takes energy for people to make them.

>well they don't go shooting their genetic material anywhere they only do so into a healthy host cell.

This isn't a response to environment, though. And the only reason why they don't shoot their genetic material anywhere isn't because they don't want to — it's because they can't.

You do know germ theory, plate tectonics, atoms, heliocentrism used to be considered pseudoscience?
