hey guys, how do you increase general intelligence?
increase iq and etc.
General knowledge like in politics, science, history, art, business, languages and etc.
reading everyday and limiting internet?

Read stuff you don't agree with then try to figure out where/how/why they have a different perspective.
Broaden your search, you can find some challenging cases where you must put yourself in someone's place to better understand their thought process.
Even if they are 'wrong', the experience is usually a valuable one.

Why do plant leaves sleep?
4 posts and 1 images submitted.
>>
from what i remember from a botany course I took, some plants automatically open/close their leaves to conserve water vapour from drifitng out of their stomata. similar to if you have a prolapsed anus and sat down on a chair, they are trying to limit the amount of water lost during the night

also that picture is wrong, the darker part of the leaf is always up top due to a higher concentration of chlorophyll
i could be wrong but whatever
>>
>>9094676
addendum:
i dont believe it is really understood how this process works.

same thing with plants always growing upward and towards the sun, nobody knows how or why it works.
you can take a seed, turn it upside down in the dirt, and the plant will literally do a double take and grow upwards to pierce through the dirt and make it to the sun.
put a plant in a box with a hole at the bottom, while taping the plant to the top of the box, and it will grow downward to the slightly sunnier hole, then out into the sunlight

crazy shit man, plants are fucking scary sometimes
>>
Plants grow when it's dark. If a plant is covered by a shadow, it'll grow till it is no longer in the shadow. (it'd have to be a semi-permanent shadow as plants grow slowly) This gives the illusion or effect of growing towards sunlight.

The reason they grow in the dark is because they aren't photosynthesizing. Photosynthesis actually takes a bit of work, and it's easier for plants to concentrate on one thing at a time. Growing or eating. This process of pulsing working/resting is call respiration and it's something all life is required to do or else it doesn't meet the standard scientific definition of life.

Also, plants can sense gravity. They know which way is up.

I remember reading that there's no significant evidence that these kinds of games improve much of anything (outside the ability to play the games themselves). I mean it's better than doing nothing, but why not go improve practical skills like math or programming. At least considering there's a lot more depth and breadth, they have a much better chance of translating to general intelligence

What Algebra have you had so far? If none, Fraleigh's First Course. If you have a strong background, you can read the chapters on groups from grad/adv. ug texts like Lang, Dummit/Foote, etc. If youre doing research I can't help, ask your advisor

Also a ton of other books. These are just the only ones I've picked up. If you look into Rubik & friends' book on the Rubik's Cube, you might find it surprisingly useful for studying finite groups.

If they're a singularity what does rotating mean for them?
Supposedly the solution is that rotating black hole 'singularities' are actually circular. But what stops a circular singularity collapsing to a point?
And whatever the singularity is like, how do the effects of any spinning it does make it outside the event horizon to distinguish it from a non-rotating black hole from the outside?

Conservation of angular momentum keeps it spinning.
It appears different because of frame dragging, where it literally pulls space around it (causing objects to be pulled around it as well as towards it). This causes it to lose its angular momentum slowly though.
>>
This is going to sound retarded and probably is, but suppose that the spin dissapears as it becomes a point mass: whatever is spinning around it would maintain angular momentum, and possibly through some sort of black magic bullshit, even gain it, meaning there's still rotating mass about the singularity.

So we've got something like 7 planets in our solar system that can sustain life, do you think there's any life on those planet s that have gone into space? What if the gravity levels are low enough that hydrogen can float and water mammals are essentially conditioned to fly? What if this means that other planets have achieved flying squid creatures? If this sounds like a rash concept think about if a planet like Pluto had a rotational orbit and a magnetic field to the point in which it could sustain life conditioned for incredibly cold environments with little oxygen, all energy generated from minimal amounts of light, flying squids could very well be a possibility.

Is there a name for an algorithm that looks at various statistics and generates a score between 1-10? Much like http://www.coingecko.com does with the various cryptocoins? How do these algorithms work?

Pic unrelated

Any algorithm or formula that generates an arbitrary score can be put on a range like that. just take the biggest value and measure the others relative to that. It seems in this particular case they're not getting 100% in any factor so they may be just comparing it to historical high (that would explain it but it may be other thing).
Then, you can make it as simple or as complicated as you like. For example 1 plebbit comment add 1 point to the score is a possible simple algorithm for measuring popularity

I plan to go back to school to study engineering at 23. I left university a few years back in my 2nd year because of personal issues, general immaturity, and a poor work ethic. Because I was studying something non-STEM and will now study STEM, I'm going to start at a community college and then transfer elsewhere.

Will my past transcript from a few years ago affect my GPA on a transfer transcript? Like if I get a 4.0 in community college and want to transfer elsewhere to finish bachelor's, is my GPA from another college 3 years ago going to mess up my chances, or is there no way for admissions to see that if I don't include it? I couldn't find an answer to this anywhere online

Your transcript will follow you, and you can't just not include it. There's a number of things you can do though. Try to figure out if you can take remedial classes for those classes you did bad in. If they're transferable between your community college and the university you were at, you can take the same class over again at community college and they will average the grade for that class. If you're not sure, talk to your old university and try to work out an agreement.

The other good news things are
- transfer admissions could be less competitive than standard admissions (easier to get in on the whole)
- most universities take at least a little bit of a "holistic approach" when looking at grades. So if they see that you didn't do well, then took a long break, and now you're getting straight As, they'll take that into consideration during admissions.

However, you must to include your transcript. If you don't, it's "lying about a transcript" (by omission) and will get you kicked out of school. The most important thing you can do now is do very well in community college this time around and mitigate some of the damage you did before through remediation.

hello /math/,

i built a wifi+gps device i carry aound town in a backpack to map wifi hotspots.

every five seconds, my software gives me current lat,long and a list of found hotspots, with their "power" rating (1 - 100, where a higher number means you're closer to the ap).

when i pass by and around a particular ap, i will have a set of (location, power) tuples which should let me calculate its "actua"l position (with some obvious error).

i expect the algorithm for this already exists, but i don't know the name of it.
