(2x)2 = 4x2.
But (2x)2 = (2x)(2x) = (2*x)(2*x), using the distributive property you get 4*2x*2x*x2 which is 16x4not 4x2

What do you guys do to keep yourself concentrated on studying?
I have weak memory, so Everytime I study for 30 min and then get bored to find myself making paperplanes or drawing fractals.
I've always had a problem in concentration, I get bored easily, even though now I'm majoring in BSc of Physics.

Music. Something without vocals. For me, the right kind of music will block everything out except for what I want to focus on. I guess it takes away just enough of my attention to not leave room for anything else but work. It also helps to keep away boredom if you have a wide enough selection of music, preferably of slightly different genres/tempos.

If you have ADHD? Check and if so get Adderall. But if you don't and just and bad at focusing than I suppose you can watch motivation videos.

if you're serious, you should familiarize yourself with your university's IP policy. You might get your pants sued off if you try to sell something you you developed using resources belonging to the university.

Ah hah hah.
Hah.
The odds of a random undergrad understanding anything well enough to come up with a genuinely unique idea are pretty damn slim.
99% of the time it's just some rehashed popsci crap that's popular at the moment, applied to whatever today's topic is.

so if the human brain is sending around electrical signals it is programmed in some way.
What language is it going to be encoded in once we finally figure how it works?
if x then do y?
just math?
it must have some system to figure stuff out logically, keep the body working, make decisions etc.
Anyone know about this? I cannot imagine how something can possibly be programmed without math or language in built into the programming somehow.

to argue with the picture you posted: the brain CAN remember basic math facts, it is perhaps only the case that the synaptic pathways formed in learning said basic math facts is not strong enough.
you can learn something more strongly through repetition, for example

Is it possible for a single man to master all science? And if so, what happens next?

define "master"
>>
>>8818650
No. I like to think academics are comparable to sports. If science is mma then you physically couldn't master all of it because there are different weight classes. You couldn't be a heavyweight and a welterweight at the same time.

Knowledge of the universe is practically infinite. You will never "master" it.
I am literally the stupidest person browsing this board regularly..
I don't even know how a negative plus negative becomes a positive. No clue how to multiply and divide fractions, hardly know how to multiply and subtract them.
I lost at elementary school and it's biting me in the ass, studying to become an electronics-technician. With dreams of going for electronics engineering after.
But I am so shit at math it's painful and tears at my fragile soul. Isolating a variable is way out of my reach.. But something I need to learn.
The math books in the wiki are way above my level, and I honestly would gain nothing from reading them at my current level.
Does /sci/ have a book for dumb retards such as myself?

a negative plus a negative is still a negative:
-3 + -5 = -8
a negative times a negative becomes positive:
-3 x -5 = 15
to multiply fractions, just multiply across:
3 1 3
--- x --- = ---
5 3 15

>>8818473
> a negative plus negative becomes a positive.
It doesn't
A negative multiplied by a negative becomes a positive though
To be honest this stuff is so basic that I think you're beyond help

Maybe you should try out watching videos instead? Khan Academy is perfect for brainlets.
An ugly hag accosts you on the street and says to you, "I have two children. At least one of them is a boy."
What is the probability that her other child is a boy as well?

How to find the equivalent resistance of this? I'm so confused. Aren't all four resistors in series?

The question is asking equivalent resistance from a to b, so yes the 4 and 5 are relevant

There isn't a lot I can write here that isn't already in the video, but this is probably the most interesting documentary I've seen in the last 365 days.
Lets make a thread about this kind of propulsion system.

Project orion is one of many projects that I'm sad never happened but that I also would have a hard time supporting if it were proposed today. However, I do think that in some future where humanity
you should read The High Frontier OP, its a pretty in depth look at how a current (in the 1970's) technology space colonization effort would go, written by a respected physicist who got a NASA grant to research the same issue. If you liked this it'd be right up you're alley.

Hi, physics and mathematics double honours here.
So, I have really bad IBS, but have to drink coffee to keep working throughout the day.
So, in short, I was forced to use the latrine, however it had been recently cleaned and my faecal matter is quite dense. Anyway, I ended up getting splashback including the bleach in the toilet (which may have entered my anus).
Will I be fine?
