Infinite series is surprisingly useless. Maclaurin series in not needed in a world with calculators
Anything after calculus.
If you flip a coin 3 times and it lands on tails each time, is the chance of getting tails again 50% or 6.25%?
>>7688709
50%
>>7688709
It's a 50/50 chance, so you average 50 and 6.25 to get 28.125.
>>7688709
What if the previous owner of the coin flipped it tails 100 times in a row? Would you expect the chances of flipping it tails again would be incredibly low? Of course not, which is why starting the probability count when you flipped it 3 times ago is ridiculous. It's always heads or tails is always 1/1
What would you change about us humans in order to create a better society, to benefit our species, to overcome our weakness, to help us evolve.
To make us look at ourselves as a single entity, allow us to explore the cosmos, to reach a new frontier for the human race.

Every single penis would be of exactly the same size. Imagine all the wars and fights we could avoid.

I would make humans a foot tall so that we can support a larger population. They would also have a mean IQ a standard deviation higher than what we have currently. Everyone would be dark with brown eyes because white skin and light eyes is linked to macular degeneration, and skin cancer. People would have that rare allele that means you only need to sleep 4 hours.
What program/method is the best way to making logic circuits? I don't know what to use.
>>7688598
In uni we used quartus
http://dl.altera.com/?edition=lite
>>7688608
is there any other way? I don't really want to download that large of a program for this, we'd only be on logic circuits for the next few days
>>7688598
I'd highly recommend JFLAP.
The software website looks like it's straight out of the 90s but the program itself is fantastic.
If it asks you to fill out a form, just leave everything blank and hit submit and it'll work without you having to give it any information.

What does /sci/ think of Louis Pasteur's theory about microscopic beings invisible to the naked eye living among us?
That's stupid. Everyone knows that it's bad air that causes diseases and that they're cured by getting rid of bad blood. Now don your aromatic mask and go put leeches on people.
>>7688382
> microscopic beings
HAHAHA
The only living thing that approaches being microscopic is your penis OP
You mean like tardigrades?
Theoretically speaking, If you throw a ball into a wall infinite times, there is a chance that the ball will phase through the wall because the atoms of the ball might avoid the atoms of the wall completely.
So how would you increase this chance ?
>>7688345
Throw the all at the wall 2Xinfinity times.
There are different kinds of infinity you stupid bag of shit. Define which one you're talking about.
>>7688363
numerical one
Why aren't you innovating yet?
Why are none of those gears properly aligned to any of the other gears? Why are there three gears right in the focus in pretend-alignment that are looped such that they are impossible to spin?
>>7688370
It's not a flaw it's an innovation.

I have been chewing on this idea that planetary material is distributed through the mantle in a toroidal density pattern. The convection patterns would follow this as well.
Could explain why most of our terrestrial planets have a large ring or plateau at one pole of their spin axis.
Written a bunch of stuff explaining it further, too. Poke holes in this idea please.
Are there aliens inside the torus?
>>7688329
No, just hot dirt and nickel

Indeed. I wish I knew anything about Geology or Geophysics so I could be a suitable interlocutor at this juncture. Unfortunately, I am yet another useless partisan in the dialectic through which recedes the common denominator of this board's post quality.
does it concern anyone that there is huge island of plastic, and trash in the pacific ocean? i have. i have only found one guy doing something about it. i was wondering if there was a way to help.
>>7688300
I think about it. It doesn't really bother me since I'm very lazy and it doesn't seem to be affecting me directly. I'm definitely aware that we're destroying the environment though, so I'm not in denial.
>>7688300
>i was wondering if there was a way to help.
No, there's no way.
Just give up and accept it.
I feel like there is a way. there is this one guy making clothes with the used plastics. i wonder if it can be turned in to fuel..
I'm in the process of teaching myself undergraduate level mathematics.
I've done basic algebra, calculus and real analysis and next I'm looking to learn Number Theory, Group Theory and more advanced Differential Equations.
Is there a logical order to learn these in, or does it not really matter?
I've heard number theory builds on group theory, but does it do so enough that I need to know group theory before I can learn number theory?
>>7688245
why?
Math higher than basic arithmetic is a huge waste of time to learn unless you plan on actually using it for something other than doing taxes.
>>7688367
as a passion project because I'm interested

Non-mathematician here. Topology sounds pretty cool. What do I need to learn to study topology on my own?
Have only had calculus.
Picture unrelated.
Basic set theory.
>>7688214
graph theory, algebra, and mathematical logic. after that you can get into topology, and eventually manifolds.
Introductory topology book.
how to prepare for maths and physics ?
how much do i have to study everyday?
how do i revise and memorize all the formulas?
how do i divide my time?
I used to be good in maths and physics, this year my grades went down to 60% because i didn't study shit, although I can theoratically understand what's happening
age:18, senior year
math: derivability, series, inverse functions, complex numbers, 3x3 matrices(determinant and inverse)
physics: electricity in general: RC, RL , RLC(forced and free(?) ) , with their differential equations
what do
Step one: Turn off the computer
Step two: Turn off other technology (phone, tv, radio)
Step Three: Study.
Step Four: If you think you are done, you are not, go back and study.
>>7688168
This, and also you should break what you need to know down to it's tiny essential tasks. If you don't know how to, say, divide fractions, and you keep getting things wrong because of it, research how to and then you can move forward with other problems.
Have a really really good foundation.

if our bodies temperature are around 37º C, why when we are in some place at 30º C temperature do we feel heat instead of cold
Because the feeling of heat is entirely biological.
It's basically your body telling you to gtfo of the sun coz sooner or later you'll overheat.
Our body generates its own heat, especially if we are active. Without cooling off our bodies will overheat even at temperatures bellow our natural body temperature. And even though evaporative cooling (i.e. sweating) can work when it is hotter than our natural body temperature outside, it does not work particularly well at high temperatures.
>>7688159
Core temp vs external.
