Deuterium oxcide and an electrolytic substance would not create the right conditions for "cold fusion".

Try, like many others have and see for yourself.

>>8568710
Isn't this just the process for isolating deuterium for fusion experiments? I know very little about nuclear physics but this looks like a basic electrolysis set up.

We know fusion is possible because that's how the sun works; it's just really hard to get it to work properly on Earth.

Cold fusion is not possible. Fusion is where you get atoms close enough together that the nuclear forces (strong at very short distances) become stronger than the electromagnetic force. You do this by putting them at enough temperature and pressure to fly together really fast. Cold fusion is the idea that you can somehow turn off the electromagnetic force to avoid this; which you can't.

Well first off, its a circle, and secondly, it has units.

Understand?

What exactly makes the unit circle so hard for /sci/ to grok?

>>8568426
memorize the cardinal directions
pi/4 are all the same magnitude, in that case just think of which quadrant
for pi/6 and pi/3: the angle with the smaller number on the bottom is the larger angle. if you think about what that looks like and also think about the relative sizes of sqrt(3)/2 and sqrt(1)/1, you can figure out all the sines and cosines from there, and that gives you the rest of them

thats how i do it even now

Your an idiot for wanting to take drugs.

Downvoted

I've tried various racetams and really liked them. They are not going to make you smarter as much as you hope to though.

Legitimately the only personal account of non-prescription drug usage I have was that of counselling a Dutch internet acquaintance through his experiences with cocaine and how it made him an invincible social predator with no conscience and hyperawareness. Maybe I should actually try and talk with him again, he's probably tried every cognition-enhancer out there

Because it's the holidays and I'm about to go to bed!

what kind of sick fuck studies anything except alcohol during the holidays

Yea dude haha

just use your hands

>>8567964
Leave the windows open for a few hours each day. Low humidity is what is causing the adverse reaction,

>>8567999

It's winter here.

We did get a humidifier and it is helping. There's noticeable improvement, but it still isn't enough. The dust is the main trigger. Its seems like the dust comes from the dryer, skin, and other sources. No sign of mold in the house.

Check Cal Newport.

-put your main notes into some cheepo tablets.

-compile all the good stuff from homework and notes into a nice looking document file (or another nicer, smaller notebook)

-instead of shitposting on your phone or playing angry birds when you are taking a shit or waiting for your big mac, read a page or two.

-do this all day and it adds up to a couple hours of study time

-enjoy not having to cram at the last minute or do power study sessions every week

OP here, wanted to wait until the thread got rolling. I'm currently learning Gregg shorthand (Notehand series to be specific). I know a lot of people don't think it's worth learning since we having recording tech now, but I like it because you don't have to go through all your recordings, which may be several hours every day and you can increase the amount of notes you take in class within the same time period. Plus since I rewrite a lot of my notes back to longhand after class, so it forces me to reread my notes

The simplest shorthand worth learning is Speedwriting

pic is not Gregg, but it looked nice

1 ton

>>8567135
That's what I thought, is it only counter intuitive to me?

>>8567133
>>8567138
why would it be anything but 1 ton? Speed/velocity will not effect weight.

I think you may be confusing this with what people may colloquially refer to as "force" when talking about accidents.

>what is analytic continuation
I'm only toe deep in calculus but isn't OP wrong (aside from other problems) because zeta(s) is only defined for real part s > 1 without any other fuckery? Why do people keep falling for this meme?

>>8566862
>assuming the existence of R
>wildberger.jpg

>>8566868
Because even 6-graders (that is, majority of /sci/ population) can comprehend its absurdity and say "lol math us so crazy)))) :DDDDD".
You are right, zeta function is defined like that only when s>1, the analytic continuation doesn't have that form.

His software sucks.

>>8566576
Self-important guy who's also genuinely fairly important. Hurt his influence by making dubious predictions about how important some of his work was, and by upsetting another self-important guy who was a lot more charismatic. The latter used him as a tool to show how great and understanding he was.

Known and loved by undergrads for pragmatic reasons.

I hate the normie "lel woulda never passed calc without this guy XDDD!!" meme

Also not saying that the symbolic computation stuff isn't impressive, but it's baffling how normies are so impressed by dumb shit like natural language input ("dood I can type in 'wut is da square root of two' instead of just learning some simple syntax!!!") and searching the internet for trivia ("omg it can tell me the average temp. of lima, peru in january!!!")

>>8566489
I don't know anon, it sound like a meme to me.

I am pondering. Answer a few questions, is that how you think the brain works? Do you think the brain is a Turing machine?

>>8566080
No. Incompleteness is a fundamental restriction.

>>8566080
There are models of ZFC that contain smaller models of ZFC inside them. That's the whole point of inaccessible cardinals. But that doesn't mean jack shit for the incompleteness theorems.

It's too hard to read papers and give your opinion?

>>8565749
For what purpose

>>8565755
you could ask this about ISS itself

>>8565749
Yes, how come nobody has tried to make somehing at 1000 times the cost of the manufacturing process of his competitors?

>>8565720
Way too narrow.

That's pretty sick.
I'm a military engineer in Brazil so I get to travel a lot. That's basically it for me.

>>8565720
dawg wheres ur fume hood

>>8565530
Quantam compumeming is just that, a meme.

>>8565530
Don't fall for a stupid meme op, use your brain for something useful

>>8565530
>QED, QFT
That's kind of overkill, you mainly just need quantum mechanics and condensed matter physics
