Could it be that the same entity or force that changes the way quantum particles behave when they are being watched plays a fundamental role in how the brain works, creating human consciousness?
Would this hint to souls actually existing?

This again. You can go ahead and believe your God is hiding in the cracks, but I have to wonder why, if someone is so willing to believe in the soul, they would have to look for it in physical models. Either deterministic explanations of human origin and being have convinced you sufficiently to abandon spiritual models or there is no need to try to explain spirit with physics. This mode of trying to justify spiritual assumptions with scientific uncertainties reeks of the most rhetorical kind of apologism, playing to the aesthetics rather than reason and also seems rather defeatist.

Just grow some balls and say "science will never completely explain human consciousness, no matter how much we understand the body, the inscrutable soul will always be the dominant factor in our behavior" if that's what you believe.

Hey /sci/, is it possible to increase your IQ? If so, how?
My current IQ is 111.

I think my IQ has decreased. I started to compare how I was 6 months ago and how I am now. I've noticed that I seem to be more limited in my ability to problem solve.
>>
I have no idea what to do anymore. I don't want to be another sheep. I want to be able to solve complex problems in my head, I want to be able to be creative. But I can't.
>>
Is it possible to increase your performance on IQ tests? Yes, just study a bunch of them. They tend to repeat a lot of methods.

Is it possible to increase the thing that IQ tests are attempting to measure? Studies suggest not significantly, but there are far better ways to improve the brain than by improving intuitive pattern recognition. Just learn a bunch of things and get comfortable solving a bunch of things and looking at a bunch of things in a bunch of different ways.

IQ is a statistical thing even under the most generous of interpretations. Most intellectually-successful don't even know or care about their IQ, only those with simultaneously massive insecurities and egos do.

What is the most scientifically optimized way to make coffee?

For instance, cold vs hot brewing or espresso based on the solubility profiles of compounds in coffee beans at various temperatures and pressures and their flavor profiles/aromas, different aspects of cultivation such as strain, soil quality, climate, etc, the chemical changes in different grades of roasting and in whether or not they've been swallowed and shit out by that one mammal, and whether you should add your milk sooner or later to keep it hotter.

Not OP, but nice citations you got there buddy. . . .

I myself heard that hitting some coffee beans with a refracted ionized lazer beam in a .4g vacuum was the best way to extract the flavor.

No citations being needed in this thread of course, so my claim has as much merit as yours.

I too want to know about this; I have been thinking about talking to my doctor about how unfocused and unmotivated I am.

Literally taking a year to complete each level of math at this rate because I keep dropping out of my class. It's not hard its just that I've always been a procrastinator.
Last year my best friend turned into a veggie and I've been unable to continue school. I get anxiety because I know I have HW, studying, a test is coming up but I just sit there not able to do any of it.

tl;dr Please help me with your experiences. Need to get my shit back together

Tell me, why is common core a thing?

http://www.businessinsider.com/why-55515-is-wrong-under-the-common-core-2015-10

Here they say that
>Mathematically, both are correct. But under Common Core, you're supposed to read 5x3 as "five groups of three." So "three groups of five" is wrong.

I think that just saying "It's easier to learn matrixes later on" is not justifying this kind of learning.

I am generally against common core but have no problem with this one. Commutativity is important to learn.
>>
>>7674148
But at least on the first problem there is nothing about commutativity. In this case, the numbers commute so you could do that repeated addition operation in any way you want.

Spoken those two problems say 5 groups of 3 and 4 groups of 6.

I was wondering if there are any drugs out there which would be able to lobotomize someone down to the mental age of a child? The closest I could find was Chlorpromazine

Fuck off with your bullshit. Love wasn't necessary to avoid lions and tigers on the plains of Africa. Anything beyond a rudimentary animal-like kinship came much later after early humans had started living in small roaming bands.

True. The skull size of a human infant at birth + living conditions meant that death in childbirth was almost a guarantee for any woman up until ~100 years ago. Essentially, we only want to reproduce with people we're willing to die for.

I need some help with a physics question I can't seem to figure out. The question is: Two trailers, A and B, is beeing held by a rope. They stand still. The mass of A is 1 kg and the mass of B is 3 kg. A spring is in between the two trailers. The rope is then cut, and the trailers move in a straight line away from each other with almost no friction. Trailer A have gotten a speed of 1.2 m/s. How much energy is stored in the spring when its given that 60% of the energy goes over to kinetic energy to the trailers.

Initial momentum is equal to zero, so is the final momentum. For the energy part use 1/2mv^2

My native language isn't english, please tell me what you mean about initial and final momentum :P And if I am correct you refer to P=m'*v?

If so, I can't see how P=mass f

Cant figure out this related rates question.

A plane flying horizontally at an altitude of 1 mi and a speed of 480 mi/h passes directly over a radar station. Find the rate at which the distance from the plane to the station is increasing when it is 5 mi away from the station.

use real units faggot

Those are freedom units.

Draw a diagram. It will be a triangle, with the radar station at one corner, the plane along the hypotenuse h, the y distance 1 mi, and the x distance being the distance along the ground. dx/dt = 480 mi/h. dh/dt is the quantity you seek. Use trig.

Dumb question:

In special relativity, if you have a traveler moving at a velocity v and an observer at rest, can you treat it as the traveler at rest and the observer at moving at velocity -v? In the first case, the traveler would measure proper time, but in the second case the observer would measure proper time?

Thanks

>>7673523
Yes, but keep in mind that since they are both in inertial frames, they will BOTH measure proper time in BOTH cases. They will both see time passing slower for the other person compared to their own time- the proper time for themselves is evaluated with v = 0, so the integral is just coordinate time, whereas the other person will have a nonzero v and thus a lesser proper time.

OPs pic gives missing info. The earth moves around the sun, as the sun moves around the milkyway as it rotates around the center of the universe.

So even a tiny millisecond jump in a time machine would displace you the fuck away from earth
>>
>>7673523
There is no "proper time" all observers will measure their time to be proper from their point of view.

No, this is an equation. It is only valid for one value of x.

Is it possible to make a directed electricity weapon that will shoot lightning to the aimed direction ? Can a lazer beam create negatively charged particles in the air that the lightning source will approximately follow and spread around in the general direction ?

We can generate lightning, or something close to it, but you couldn't carry it around like that.

Yes.
