What's the name of that mathematical notation that avoids the use of brackers?
I'm trying to see if I can make a calculator where all inputs are valid.

I just realised I can't math for shit when I slept 5 hours the day before and it's the night.
Is Polish notation appropriate for spamming symbols and variables in any order and getting every possible equation given infinite time?

Could it be possible, if i want to clone myself, and i change the chromosome 23, XY to XX. Will I have my double female?

Problem is you only got one X chromosome. You'd need 2, so it can't be done i'm afraid.

A woman could do it though.

Why is dentistry so obsessed with treating diseased mouths via patchwork methods like remineralization and temporary sterilization, and mechanical cleaning? These only achieve a temporary halt in degradation that is presently taking place. They do not prevent future degradation, or remove the underlying cause of said degradation.

Why not focus on preventing oral disease in the first place via recommending a diet nearly devoid of cooked, soft carbohydrates and nearly all sugar, and prescribing oral probiotics such that pathogenic bacteria have a harder time infecting you?

Can we have a thread to discuss Genetics and Behavior?
Three major conclusions of Behavioral Genetics.
1) all behavioral traits and disorders are influenced by genes.
2) environmental influences tend to make members of the same family more different, rather than more similar.
3) the influence of genes tends to increase in relative importance as individuals age.

reared-apart twins were as similar to one another as were twin reared together on a wide range of measures including general cognitive ability, personality, religious attitudes, vocational interests, and so on.

Congratulations, OP. You just created your first containment thread.

Be pleased as it becomes full of people who don't understand the first thing about [genome-wide] polygenic scores or even genes. Be thrilled as waves upon waves of /pol/esmokers misinterpret the research you post in whatever ways they see fit to help their own personal political agenda. Be amazed as non-science people make bold claims like how you can deduce someone's genetics and thus intelligence by just looking at them.

Hundreds of posts about IQ await you! Just remember, OP. This is what you wanted.

Why does music have such an effect on us? What psychologically makes it different from other random sounds?
33 posts and 1 images submitted.
>>
>>8271944
No one knows the answer because psychology is such a new field but there is research being done. Check out some journals: https://www.jstor.org/journal/musicperception

Physiology implies a living thing and sound is not a living thing. Im guessing you mean how the psychological effect is different from other sounds. See above, and read what you can find.

fools

its about symmetric fractals anon, harmony follows certain rules of permutation which happen to produce a single composition

the more intricate and complex the repeating of harmonies is, the more interesting the piece.

I still have two fundamental questions tho

What is music and what is sound?
Does "wrong" playing and tuning exist?

Do people choose what they value in life, or is it purely inherent and inborn?

If someone is absolutely convinced that their sole goal in life is to win an Olympic gold medal in [x sport], did they choose to feel that way or is it just an irresistible impulse that they can't do anything about?

I ask because the level of effort and difficulty and personal sacrifice involved in pursuing such an achievement is almost always immense and the odds of success are extremely low, and objectively relatively little value (economic, especially) is obtained even in the very unlikely event of success (most Olympians, even those who win gold medals, don't typically make much money out of the endorsements that follow; there are only a handful of exceptions like the winner of the gold medal in the Men's 100m race, or Olympians who win many gold medals - but even they are worth far, far less than anyone on the Forbes 400 list).

It seems that this would be something that someone would not choose to value so highly if they were a rational person; which leads me to believe that it's probably some sort of inherent and irresistible desire that wasn't influenced by free choice.

Does science have a good answer to this question?

So we did not choose to write these posts?

A human being can live without one half of its brain, correct?

Let's say you took your brain, took it out of your head, and cut it in half, into the two hemispheres. Then, we'll say that the hypothetically still-alive hemispheres are put into two vats which supply each hemisphere with everything necessary to survive comfortably.

My question is, after this, would you be conscious in two places simultaneously? Or would "you" only be conscious in one of the two hemispheres, while the second hemisphere has like a carbon copy of your consciousness that diverges the moment it is separated from the other hemisphere

Has anyone here moved abroad for their PhD studies? Going to be applying to physics related programs and was wondering if anyone had some suggestions or stories. There's surprisngly little info online.

I don't really speak any other languages right now other than junk Spanish and Italian. What percentage of work/life can be conducted in English when you're in a STEM graduate program?

Ty in advance friendos

"Musk's long term vision for the company is the development of technology and resources suitable for human colonization on Mars. He has expressed his interest in someday traveling to the planet, stating "I'd like to die on Mars, just not on impact.""

"According to Steve Jurvetson, Musk believes that by 2035 at the latest, there will be thousands of rockets flying a million people to Mars, in order to enable a self-sustaining human colony"
