Anyone got some good books on vectors and proofing within 2D
Books and or online resources I don't mind as long as it explains it decently and has enough proofs for my exams on it
am I fucked boys? Can I make it?
>>9115944
No
As long as you arent taking a bunch of other hard things
Honors Analysis is basically 2 or 3 classes combined into one. Algebra can be chill if you play your cards right
>>9115944
Algebra? lol that's literally high school shit brainlet
>>9115944
Did you already do theoretical linear algebra?
What aircraft is best suited for Mars: planes, helicopters or blimps?
planes, as blimps lack sufficient atmospheric pressure to fly and thus have a very hard time being "less dense" than the barely existant atmosphere, and helos suck all around.
>>9115935
I should've used the word airship, not blimp.
> have a very hard time being "less dense" than the barely existant atmosphere
What if there is vacuum inside?

Is there a formula that can determine the energy released when a finger nail is clipped?
What about it's speed and trajectory?
Is this the solution to cold fusion?
Derive the Cauchy stress tensor for the nail to find the force exerted on the clipped part
Hi, sci--
I'm in need of a good introductory ordinary differential equations text. I'm reviewing this for an intro 'modeling techniques' class. I tried reading my old textbook from freshman year, but I forgot it's utter dogshit. The text should cover basic separable eq's, first order linear ODE's, some case studies (Torricelli, logistics, ect), Oscillators, Laplace transformations, ect -- the usual.
Thanks in advance
Damn it sci, I'm in need here

So i have a mathematical problem. If somebody has a 1% chance of dying, and by working out, he decreases his chance of dying by 47%, what is the probability of him dying in the end?
percentages are the source of undo befuddlement, use probabilities instead: 0.01*0.47 ...of course someone can attempt to interpret the english "decreases ... by" but this answer should be clearly defensible at least.

shit thread because what should be argued against is the (misnamed) Continuum Hypothesis (it's an axiom - an hypothesis can be tested) that goes against all intuition and reason.

I notice that you are already a partisan in your own chosen affair. It's kind of cute.
I have stumbled upon the greatest question of this decade.
How will homo felis, also known as cat humans wear glasses?
A pair of glasses mostly relies on the ears to carry them. The ears of a cat girl are located in a higher place than normally. The nose alone is not enough to carry them, so how will cat girls with vision problems be able to live normally?
(No, there is no such thing as contact lenses)
They hang from ears instead of resting on them.
>>9115669
like a thread bound around the ears?
pic related. It's the first draft of the design
>>9115648
What if they have two pairs of ears?

Also exceptionally impressive the speed he was able to learn Icelandic.

He is a trained mnemonist and he has competed in memory sports.
He has also worked as a clairvoyant for "financial reasons".
Synesthesia is a thing but I would not trust anything he claims.
There is a post somewhere in the internet which analyzes his YouTube video where he displays his calculation abilities.
He is basically a fraud in this regard.

Discrete unless your measurement device uses a continuous property of matter.
>>9115627
>continuous property of matter
>>9115628
I was using OPs terminology, non-discrete could fit you.
Time is measured by physical observations, time is only as continuous as your ability to measure it.
This is a stupid question. Assume you have a laser going 1 meter straight forward. You then refract the laser through twisted fiber optic cable or through a bunch of mirrors or something such that it travels the same net meter, but over a longer path. Relativity doesn't imply that it would take the same amount of time to travel that net meter right? It's still longer route = longer time? It's just observer speed that causes relativistic effects?
>>9115612

>>9115612
Yes, it would take a longer time. If I bounce a laser to the moon and then to one meter in front of me, it still travels a "net meter" - just over a much, much longer path, therefore taking longer.

Girl problems?
Brainlet here.
I have always been a failure academically, I'm 24 years old and far away to actually graduate from College.
I have tried every "technique" of study and not a single of them seems to work on me.
My reading speed is slow, I have short attention span, my "working memory" is shit.
I also take time solving as many problems as I can, and when I do my exams, I simply can't remember how to solve some of the problems, or can't answer them in time.
My classmates usually have superior performance to mine despite some of them studying way less. They are "faster", too.
Even if there's genetics and IQ involved, is there any kind of "mindhacks" exploits, or even medication I could use, to at least have my capabilities closer to the one those people have?
I'm already using the Ritalin meme and this shit has no effect on me.
LSD is probably worth a try
>>9115588
Are you healthy?
Sports, a diet poor in sugars, a tight sleep schedule, ... these factors help long term.
You should stop taking Ritalin at the moment.
You should also realize that you can increase attention span and working memory.
Then, being depressed and anxious doesn't help so be more happy.
Play Dual n-back.
http://brainworkshop.sourceforge.net/
It helps you increase attention span and working memory.
It will be a working memory related to the game and not *mathematical working memory* but surely there will be some transfer it you follow some simple instructions.
Focus on the game and not on your mental chatter.
Play it for 15 minutes every day.
