Is emotional intelligence real?
11 posts and 1 images submitted.
>>
Intelligence is (usually) defined to be someone's ability to learn new skills (NOT emotions) quickly.
So no. If you're an emotional person, you're just emotional... "emotionally intelligent" is like saying "furiously exist". It doesn't have any meaning.
>>
>>8196112
no. it is a made up attribute to make people who are bad at thinking feel better.

what is true, is autism spectrum disorder. look it up if you want to learn some actual medical science
>>
No. I suppose you could consider it to mean someone's ability to read other people's emotions (at least I think that's how people traditionally use it), but the problem with that is it's entirely dependent on the people around them. If they happen to be similar to their peers they're going to be able to read their emotions. Unlike actual intelligence, it's a measure effected solely by outside influences (while real intelligence is something that's specific to the person who's capable of reasoned thinking).

Sup /sci/. Doing some physics work when I come across this. Having a brainfart, I fail to recognize what I'm supposed to do. These are two separate fractions, correct? Is multiplication between the two fractions implied when there's no sign or parentheses?

Yes, just like every other situation in which two symbols are adjacent in undergrad math.

What's at the edge of the universe?

Is the edge of the universe penetrable?

Does it even have an edge?

What's even the geometry of the universe? Is it spherical?
106 posts and 8 images submitted.
>>
There is no edge, it's infinite, and don't let anyone else tell you otherwise.

This is the problem with a finite universe, you can't imagine it. What's outside the edge, then what's outside of whatever that is?

It's illogical to think it's finite.

Don't know if it can bridge like a typical physical space.
>Does it even have an edge?
Don't know.
>What's even the geometry of the universe? Is it spherical?
It's thought to be flat, which doesn't necessarily imply infinity of any sort.

Infinity vs finity is largely feels. The notion that it isn't finite seems nonsensical to me, however. Improbable and almost disjointed with everything else the universe appears to be.

Share your lab stories. Here's mine:

First genetics lab. We need to rip the heads off from Drosophila pupae for their gigantic chromosomes. One girl with Aspergers starts crying and yells that she's going to quit because it's so wrong, fruit flies have freedom to live too. She lies down on floor and then hides underneath a table.

First biochem lab. The same assburger loses her mind because cheap Chinese plastic tubes melt in the PCR device. She starts crying and hides underneath the laminar. After 30 mins she starts to tell everyone about Aspergers, her hypothyroidism, how her feelings are completely justified etc. The lab assistant and lecturer sigh in despair.

Animal physiology lab. A small blood sample made her faint and cry. Frog decapitation and dissection makes her vomit and rage quit the course. The lab teachers are extremely patient, but she is constantly testing them with her stupid shit.

And after all this she specialized in animal physiology because "genetics has too much math".

My only experience in lab as an undergraduate is that I don't generally trust my lab partners so I prefer to do the lab myself.
Inconsistencies that throw off results piss me off, and my partners usually want to finish in a hurry and leave before lab ends so I tell them to act occupied and let me type the reports and perform the lab, unless my partner has integrity to do it right the first time.... Sounds jerkish but I've been screwed by relying on lab partners before

Can someone explain what the notation h'(x)->infinity as x->0- means based on this graph?

I would expect it the line to be going straight up if h'(x) is approaching infinity when x approaches 0 from the left?
14 posts and 3 images submitted.
>>
Is it to the right of 0 x is approaching infinity and to the left of 0 x approaches infinity? Of course, that's it, but have you ever seen it described this way? seems fucking returded
>>
>>8196712
the superscript tells you which direction the limit approaches from

0+ means you're coming in from the right (more positive side)

0- means you're coming in from the left (more negative)
>>
>>8196728
and so h'(x) going to infinity as x goes to 0- means that the graph approaches a vertical line as you approach 0 from the left

I keep seeing all these magical 'POWER YOUR OWN HOME FREE TESLA GENERATOR INFINITE ENERGY AWAKED YOUR PINEAL GLAND FORBIDDEN KNOWLEDGE' on Youtube, and surprise surprise they all turn out to be bullshit.

So I figured I'd ask here, is there such a thing as a fancy generator that I could build and use at home?

By fancy I mean something that isn't basic like wind or solar.

I feel like I have some very important work to do, but I don't know what it is.

I know that once I figure out what I'm supposed to do I will excel at it..but I can't figure out what it is. I've been sitting here all day and no ideas came to mind. Anyone else feel the same?

I think I can understand OP. I always feel like I "should" be doing something to learn something new or useful on my own, but I'm too lazy to ever do any extra work and I can never decide on a topic that I want to study on my own.
The few times I'm ever successful is when I just pick a topic and run with it. I think the majority of the difficulty comes from deciding on and starting something. I guess I need more of a "just do it" kind of attitude.

So what gives /sci/? I know a smaller class is better for learning, engagement and building a relationship with the professor. But by the looks of it there is only going to be 3 people in an upper level class. Is physics becoming a meme degree? I also noticed it's a huge sausage fest.

You find yourself in a situation where you have managed to produce a correct, constructive proof that P = NP by providing a polynomial-time algorithm for an NP-complete problem. Let's also say that this algorithm happens to have an extremely practical running time, say O(n^2).

Ignoring whether or not this is possible, what would be the 'right' plan of action to take in this situation? Such a solution would have an extreme effect not only on the academic sphere, but also on the life (and potentially safety and privacy) of people around the globe. Do you (a) publish your work in a public, peer-reviewed journal or conference, (b) keep your work to yourself, or (c) do something else entirely?

The balloon's surface is composed of finite points. It is not magic, it is a balloon.

>>8195271
>Ok, give me the reference frame where the universe is stationary and I will always be able to give you one where it is not.
I can think of no instance where the universe as a whole has changed its location in any spatial direction. Therefore it has undergone no motion, has no possible direction, and is stationary.

>The balloon's surface is composed of finite points.
Defend this statemate. It can be representated in uncountably infinite real space, there's no reason to assign a finite number of points over an infinite.
>>
>>8195304
The balloon is a finite object occupying a finite number of the universe's possible positions. The universe does not afford infinite precision or infinite subdivision of space between two arbitrary points.

If the balloon exists in a vacuum that is otherwise the rest state and minimum excistation of its underlying fields, as you expand the balloon you're just distributing the excitation gradient of its components more widely. The balloon is not gaining new energy, nor does it gain new points. It just elongates the distance between its excitation peaks and distributes the falloff further.

There is no reason to assign the balloon anything other than a quantized state.

(A finite range, and quantized state.)

Hello. I would like to discuss the problem of developing AI with some experts if possible. Am a comp sci student and recently started an Algorithms course referencing Introduction to Algorithms by Cormen, second edition.

We had a session on few of Turing's papers a while ago and as I recall he considered the brain to be a finite-state machine and hence emulatable. I got not problem with this line of thinking.

The algorithm course however introduces NP complete problems that do not have a computational procedure that always give the efficient solution. This got me thinking that wouldn't a self dependant AI need to make its own algorithms? Does there exist an algorithm for algorithm designing with even partial emulation of human logic?

I understand self learning machines exist but don't they just copy what humans do? What happens when a new unknown situation arises?

Example of an NP complete problem from the book:
Given a central warehouse and a delivery truck. Find the most efficient route to deliver goods each day.

Self bump. Anyone can participate or ask stuff.

To add to my previous point, isn't the need for a step by step procedure the result of sequential processing by computers at an hardware level? Are there different system designs available?

I think the brain uses analogous signals rather than discrete. This would explain its huge capacity and imprecision. Would an analogous computer be better equipped to emulate human logic?
