if my water pump is capable of 40psi and i have a hermetically sealed 30L water container, does that mean that if I use the pump to half fill the container the pump will almost be at its pressure capacity since PV=RT? Meaning the pump will only fill about another 7L into the tank, albeit slowly?

Einstein & a Indian sitting next to each other on a long flight...

Einstein says:
"Let's play a game...
I will ask you a question,

you pay me only $5
and
if I don't know the answer,
I will pay you $500..."

Einstein asks the first question:
What's the distance from the Earth to the Moon...?

Indian doesn't say a word,
Reaches his pocket,
Pulls out a $5...

Now...
It's the indian turn...

He asks Einstein:
What goes up a hill with 3 legs
and
comes down on 4 legs..?

Einstein searches the net and asks all his smart friends...
After an hour he gives Indian $500...

Einstein going nuts and asks:
Well...
so what goes up a hill with three legs and comes down with four..?

Indian reaches his pocket and gives Einstein $5...

so...given a vector V1

if in 2D space vectors orthogonal to V1 ocupy a 1D space
and in 3D space vectors orthogonal to V1 ocupy a 2D space
then
it follows that in 4D for any given vector V1 there should be a 3D space of orthogonal vectors right?

The original reason given for Autism was 'refrigerator mothers', basically neglectful mothers. The symptoms of maternal deprivation and Autism are basically the same. I'm wondering if the original reason was actually correct.

https://en.wikipedia.org/wiki/Refrigerator_mother_theory
https://en.wikipedia.org/wiki/Maternal_deprivation

It's possible that their poor emotional ability is due to long term maternal neglect. Perhaps the high IQ autist, is actually a high IQ man with emotional trauma. Are there any cases of low IQ parents having a high IQ autistic kid?

Quote from the refrigerator mother Wikipedia page

>According to Peter Breggin's 1991 book Toxic Psychiatry, the psychogenic theory of autism was abandoned because of political pressure from parents' organizations, not for scientific reasons. For example, some case reports have shown that profound institutional privation can result in quasi-autistic symptoms.[17] Clinician Frances Tustin devoted her life to the theory. She wrote:
>One must note that autism is one of a number of children's neurological disorders of psychogenic nature, i.e., caused by abusive and traumatic treatment of infants. ...There is persistent denial by American society of the causes of damage to millions of children who are thus traumatized and brain damaged as a consequence of cruel treatment by parents who are otherwise too busy to love and care for their babies.

Psychiatry is not immune to political pressure. If Autism is real, then it should be detectable in the genes and fMRI brain scans. Autism brain scans reveal minor differences which could be due to trauma rather than anything genetic.

https://www.youtube.com/watch?v=6CUn81EBVGM
That's a video on identical twins where only one has Autism. How is this possible if it's purely genetic? One of the twins should have higher amount of environmental toxins in the blood, if that is indeed the cause as some speculate, but that also has never been proven.

What are your thoughts /sci/?

>>15471893
If autism was something that developed during childhood as opposed to pre-birth than it wouldn't have a distinctive "look" or set of facial features attached to it. By necessity it's either genetic like downs or caused in the womb like FAS
