Left or right?

What's the scientific effect on our brain while trying to figure out optical illusions /sci/?? Is it good for your brain trying to figure these out or what? Also gif related it's either clockwise or counter clockwise, what determines what we see and if we tell our brain to see it another way, why doesnt it listen? Explain

This one is more fun
If you can't alter your perception of which way it's spinning you have low IQ

Thanks for answering my questions so far - again - I just don't know what I don't know so I'm confirming anything I could interpret ambiguously or make an improper interpretation of without knowing otherwise.

>1. Why would you create an equation to acquire an "expectation value" of "any physical variable"?

>Is this so you have a placeholder for anything you can measure empirically in terms of joules or kelvin in equation 2?

>2. All states of the system, does that mean:

>A. All aspects of a stirling engine in a cycle it goes through and its energy sources?

>B. The full range of states of something like H20 - gas, liquid, solid, etc.

>3. Numerical coefficient of the order of 1.

>Does this just mean it isn't to the power of anything other than 1?

I've been saying it from the beginning you can easily shift your own perception of the dress by shifting how you perceive its environment. However, I've come to believe that is easier for some people than for others. It's like the spinning dancer that your brain can see spinning one way or another, most people can switch directions at will, but others have difficulty. I don't think it's a matter of intelligence, because my friend Jeremy is one of the smartest guys I know and I spend my career interacting with very smart people.

>Also, has anyone studied what happens when a subject switches how he 'views' an optical illusion like pic related?
Another excellent question. Short answer: Yes, this has been studied.* The phenomenon is called bistable perception.

In essence, only one precept can exist at the same time: In your example either you see the young lady, or the old woman. The alternation between these two perceptual states is mediated by visual attention, where one representation is given priority in visual cortex by selectively boosting and/or suppressing neural activity. The example of the spinning dancer I attached here has also been extensively used to probe at the neural correlates of bistable perception. One can perceive it either as spinning clockwise or counterclockwise, depending on attention. When participants are asked to indicate when a perceptual switch occurs while their brain is being scanned, activation of the right parietal cortex can be found. Furthermore, this region becomes functionally coupled with brain area MT, which is responsible for motion perception. Parietal cortex is therefor hypothesized to orchestrate the alternation between these two perceptual states of motion.

Alright, I think this is enough internet for me to day. I'm catching an early flight tomorrow morning, so I'm going to bed. It's been fun.

Hey /sci/
Is it possible to go inside a cloud? My girlfriend says that you cant because it is made out of gas but i say that you can go inside it because you can go inside it because its a cloud of gas?

So who is correct?

It's simple if explained that way but for a 19th century scientist, who assumes ignorance with dealing with the subject, it is possible that we may have evolved to reverse the retina effect anatomically by the way the eyes connect to the brain, as oppose to neurological image processing.

If the prior was the case, the brain would probably not adapt to flipped image very well.

which way is she spinning?

Can two objects approach each other faster than the speed of light?

What determines location in space? Can you actually distinguish variation in space or location without matter? Or is location relative only from matter to other matter?

I’m currently a Jr. in high school and I was just wondering what people thought the best Physics and Calculus textbooks are? I plan on majoring in physics and want to review the best college text early.

As far as I know, it's true.

>his weak challenges of quantum mechanics are taken seriously because of an IQ number

Fuck him imo. Prodigies are dime a dozen, they rarely become anything. This kid has wasted potential written all over him.

I think its about controlling your emotions and programing your brain like a machine, so every feeling you get is tied with a positive emotion with it.

pic related, make her spin both ways

>>2372835
Its a Jedi mind trick. The ambiguity is there, you just fail to see it.

Is this woman spinning clockwise or counter-clockwise?

use the force

control it

Hey, /sci/, I don't usually go on this board since I can't understand half the stuff you guys are talking about; however since you're all so smart, I figured you would know, or at the very least have an idea of why I'm right-brained but am right handed.

I've been using my right hand my whole life, and I took the "dancer" test in which a girl spins both clock and counter-clockwise, and depending on which way you see her, it gives you an understanding of whether you are left or right-brained. Consequently, I found that I'm right-brained. Also, I'm an INTP, and from what I've seen, most INTPs are right-brained.

One last thing I want to add is that my writing is horrendous, which makes sense if I truly was meant to be left-handed.

Pic related; it's the dancer.
