If you don't get what these words mean, and think they're only "buzzwords" then you're just a fucking dumb undergrad.

Like any large scale commercial crop farmed on industrial scales its smothered in herbicides, pesticides and fertilizers.

You can grow your own but hard to cure properly, also need rich soil.

I wouldn't worry too much about it, no one gets out of life alive, might as well be one with the chemical industrial complex at this juncture.

You make a lot of weird chemicals when you burn the tobacco and the paper, and the paper is treated to burn slowly

>>7989707
That's not true about the additives being harmful. The issue is that tobacco has things like tar in it naturally that damage the lungs and cause cancer (and aren't really filtered out like they would be when you hookah). Plus you're doing a direct burn (as opposed to just heating the tobacco enough to vaporize the nicotine). This is what's harmful. Finally, it's not like tobacco has any kind of anti-cancer agent like CBDs in cannabis to offset this.

It looks like American Spirit is just trying to appeal to the natural food idiots who smoke (you know, the people who are afraid of "chemicals").

Stefan-boltzmanns law?

Transitioning electrons emit photons.

>>7997107
What do you mean by transitioning?

If you heat up a metal, it goes red hot and emits photons. (Correct?)
What happens if it cools back down to solid and you heat it again? Have the photons returned to the metal? Thanks

I don't think Biology is very hard at all, and I'm a bio major. Unlike other sciences that tend to "build" off one-another, biology is more or less like moving to the side, for most undergrad stuff at least. Taking other bio classes makes it easier, but just getting in is by no means very hard at all if you pay attention.

>>7996607

I would say that as a rule of thumb; the more classical the subject sounds the easier it is for starters, like botany or zoology.

I've known engineers and other non-science students that don't know that DNA translates in triplets or what an aminoacid is or its structure(or at least the usual position a certain aminoacid takes in a protein) which depending on the teacher/matter can give you bigger problems or not.

>>7996591
What does Biology I contain in your uni? Is this an American term?

>>7996607
Depends on the bio degree I guess. Some degrees are more focused on mol. bio, some others on zoology or botany; in some degrees you can specialise and build off of previous knowledge. The thing with bio is that it spans many more subjects than other sciences and bio degrees attempt to help you scratch the surface of each topic.

>>7996641
this is correct

>>7995720
what's wrong? you didn't actually learn and you figured you'd cram for the single big test?

tough luck brainlet

>>7995724
too much stress

I used to be an A student and I don't want to admit that I'm trying to "just get by" with B's now.

Though my nuclear physics class got utterly fucked this semester by academic politics.

>>7995724
The brainlet meme is no better than gorilla posting.

You're shitting up the board.

okay what is with all these graphene threads
are we being raided by a shill company or something

>>7995042
Does such a thing have any purpose besides a neat desk ornament?

Why is this the only thing we should be hyped about?

please shut up

>>7994734
I give up, why?

>>7994750
i dsont know

You'd probably have better luck over at /diy/ for stuff like this, they have a whole general for amateur electronics

>disadvantages to this approach?
Don't think so, but eddy currents are merely a side effect, what you use here is the motor as generator and the resistor dissipates the energy. Zener diode or VDR as overvoltage protection parallel to the MOSFET.

>>7993963
So when the MOSFET goes to OFF state, won't the voltage over the motor spike because of the self inductance of the windings and the sudden change in current?

I can't tell if your intelligence is below average or normal just from this post, but I'm almost certain you have an anxiety disorder. Med student, going for psychiatry.

Joel is that you

If you like ika-chan you can't be all that bad.

I think so. It also seems like it would crash into the front of treadmill as soon as it did. I don't know shit about physics though.

>>7992852
Is air passing rapidly over the wings? Then no

>>7992857

What if there was a fan at the front of the treadmill?

but it doesnt mean they are girls only.

nothing more interesting and alarming than Crispr-Cas9 atm.

Nothing past the asteroid belt will ever be colonized because the Jovian system and other parts of the giant planets are steeped in deadly cosmic radiation you could never protect against realistically.

I think it's time to crack out the Cowboy Bebop boxsets again

>>7991475
would they not have a strong enough magnetic field to provide enough protection?

No downsides at all. STDs are madeup by the government in the pocket of Big Condom and women only become pregnant by swallowing sperm and not from sex without condoms. Don't believe their lies.

>>7996537
>I feel we live in a age where public perception has been biased by condom companies marketing.

Are you an anti-vaxxer as well?

Anyway, unless a girl is on her period, there's a real chance that she can get pregnant if you creampie her.

>>7996552
yeah, but what are the real risk anon, like what does science says.

>>7996259
Because gravity seemingly works like a point mass on celestial bodies and has a radial spread.

>>7996262
So what creates gravity?

>>7996263
What do you mean, its a fundamental law since the big bang.

you just did the math
if numbers are accurate then yes
stupid question really
