What ACTUALLY flows is electrons. And they flow from earth to the clouds.
"Conventional" current flows down. Of course, conventional current is an abstraction. So yeah.

what?

the earth's magnetic field is reversed in the southern hemisphere, so the current flows the other way

By that logic lightning should be coming out of the earth at the north pole and going into the earth at the south pole.

>Imagine how funny it would be if you walked into a black hole with a really small event horizon by accident, you'd be there walking and then suddenly SHIT SO MUCH WEIGHT.

I said this a few months ago in a fit of retardation, was more making a joke though.

Mine is similar to this.

Some dumb bimbo told me I should drink Smart Water because it has elecrolytes. When I told her that an electrolytic compound is usually a liquid or sludge that conducts electricity, she said "Yeah, but it makes you work faster"

>>1469683

Why so unfriendly?

>>1469680

Well, now I see I did make it unconvincing didn't I?
Democracy sure works, but what was meant by that line was that there is nothing that could be better than democracy.

I sure do enjoy democracy but I would personally prefer a meritocracy.

>>1469668
Huurrr beers, was in a physics class so no. But then again...

>>1469668
>Weed kills your brain cells

That is true

>>1469710

People with anti-weed facts are hilarious. I've heard it kills brain cells, sperm, and just about everything else. No actual supporting facts.

>>1469800
>>1469710

Sauce on the information?

People with pro-weed facts are hilarious. I've heard it improces brain function, cures cancer, and just about everything else. No actual supporting facts.

>The 14 subjects from the drug treatment center all had a history of heavy cannabis use during adolescence. On average, they had smoked marijuana from age 13 till age 18 or 19, and reported smoking nearly 6 marijuana joints daily in the final year before they stopped using the drug.

Holy fuck, these are some heavy smokers. I smoke like 1 joint a week since I was 21...

>>1469849
>unimaginative non-weed-user unable to consider the possibility that he is greentexting a person who does not smoke any form of drug

>>1469852
yeah youre probably fine then

>>1469852
The main trouble with these studies is that the subject almost always smoke tobacco in addition, or even at the same time. Good data basically does not exist.

>>1469855
>Weed addict gets butthurt and pretends he isn't addicted and butthurt

>>1469865
So the tobacco caused the brain damage?

>>1469871
>raging retard greentexting a person who is actually an alcoholic

>>1469876
Sure. Why not.

Some theorize that photons might have mass.

>>1469876

Seriously, I doubt it.

But hell, if they smoked even one joint a day not fucking 6 I could believe they would be brain damaged.

How desperate you have to be to smoke since you are 13? That's just not a good idea man, now way how you look at it.

>>1469879

>>1469897

Well shit, if some kid starts smoking at 13 I bet weed is not the only one of his problems.

Even still, it is a drug, no wonder with heavy use it can be dangerous.

>>1469898
>Implying i mad

>>1469957

If a kid is smoking weed or tobacco at a young age then he's almost certainly also drinking and has a shit diet to boot, not to mention failing at school.

2 years ago, I was 16.

I smoked weed most days during the summer
Got drunk at least 2-3 times, hard, each summer
I was 5'11 and 135 lbs, my diet was fine.
That year in school, I had a 4.0 GPA.

>>1469972
>>1469987

>>1469994
What does 4.0 GPA mean?

>>1470007
Straight A's in every class

(actually had a couple B's, but they were weighted courses, so it counted as an A)

>>1470012
Oh, thanks.

>>1468885
Technically light has relativistic mass by virtue of possessing energy. It also has momentum a la DeBroglie.

>>1470012

Thanks, I was also curious about that.

In my european system Straight A's(5's) would give you and average of 5.0.

And same here, last year I had a very plentiful harvest and smoked almost every day for one semester. Also straight A's. But I guess that what happens when you enjoy your field of study.

>>1470048
You'd be surprised, most of it was borderline for me (90-92%) in the class, and I put in a decent amount of effort.

The science classes I managed to get above 100% every year, but that's just because I enjoy the subject.

Math classes are relatively difficult, and all of the other classes (history, English, foreign language) is the same as in Europe.

>>1469994
i don't think /sci/ counts anecdotal evidence as valid evidence.

>>1469994
That's both an anecdote AND a self-appraisal. I don't think this evidence is terribly valid.

>>1470025

ALL OF MY HATE

>>1470094
>implying there's any other way of proving something to someone on a subject like this

>>1470076
>100%

What?

>>1470109
>>1470094
What else do you want me to say?

I don't quite understand what you guys are implying - are you implying just because a kid experiments/enjoys drugs and alcohol while he is still young he will become/is a loser?

I know this isn't true.

>>1470125
The classes are extremely easy, AP gets a bit harder during junior and senior years.

Freshman and sophomore high school science is unbelievably easy, yet many kids are struggling with it. The classes have a lot of extra credit

>>1468753
Trollin' much?

>>1470134
It wasn't an intention greentext.

I was just wondering how you managed to get over 100%.

No schools I know of ever give out more than 100%.

>Electron microscopes are better than normal microscopes because electrons are smaller than light.

>>1470143
Each semester, about 6-7% of extra credit is allowed and added on. It's mostly a thing that the science teachers did at my school.

For example, during 9th grade, we had physics/chemistry. During the chemistry portion of the year, the teacher would just put a piece of paper on the desk with a tough balancing equation problem. If someone solves it, gives it to him in the morning, they get like an extra 3 points in the quarter.

And he did that like every day, and I would always take them. Most of them were really basic too

Ok, at this point... no one has posted that pic of Carl Sagan yet?

>>1470126
>are you implying just because a kid experiments/enjoys drugs and alcohol while he is still young he will become/is a loser?

No, I'm implying that kids who do this are more predisposed to become a loser because of their background. Obviously it isn't going to be true in all cases. Maybe it's less of a phenomenon in America but you see a lot of this shit in the UK.

>>1470176
In US all of the kids that smoke weed, that I know, actually ARE losers

But it's not because they smoke weed, they've always been dumb/not caring about school since elementary school.

>>1470176
Point in case: people often act as though those kids who spent ages playing computer games and not socialising with the other kids were going to grow up to become losers. And plenty often they are right. But a few of them instead grew up to be residents of /sci/, so clearly they did something right.

>OP is not a fag

>>1470150

this sounds legit to me. not phrased very well but its true. The wavelength of an electron in an electron microscope is smaller than that of visible light, so electron microscopes can acheive better resolution than optical microscopes before being diffraction limited.

tl:dr you are a faggot

>>1470354

>wavelength of an electron

because electrons are waves, right?

In theory, it doesn't, but...

experiments have shown that at light speed, photons have a mass of between 3 and 7 x 10^ -27 eV.

Actual mass or effective mass?

>>1470622
That reads to me like we have established possible maximums for the mass of the photon, not that we've proven it has mass.

Fascinating stuff nonetheless!

>>1470658

True, I sort of got that feeling too, but then again the photon was theorized as a massless particle. I'm always a fan of the mantra "absence of evidence is not evidence of absence." It's highly debatable.

Thumbs up, anon. Particle physics is fun!
