Why does psychology not study the effects of religion on the mind?

Posted: 03 Jan 2016 03:47 PM PST

I was researching theological stuff yesterday and I came across a Wikipedia page about the psychology of religion and it said it is not widely accepted/studied.

Why not? The effect that religion has on someone's mind should be one of the most fascinating aspects of psychology, to brush it off as mumbo jumbo is extremely ignorant I believe. Psychology is the study of the mind, you would think this would be a major area of study. Who cares if its not real, it produces real effects in our minds.

Please help me understand why this isn't more pursued, I would love to pursue this type of psychology

If a magnet is in a high speed orbit, does the constant acceleration towards the center cause the field to be stronger on the outside of the orbital path?

Posted: 03 Jan 2016 07:45 AM PST

If a magnet were continually accelerating in a straight line, I would expect the magnetic field to not yet have propagated ahead as far as it has behind giving the appearance that the field is "mostly behind" the magnet.

If I'm correct on that, then it seems like an orbiting magnet would appear to have a field lopsided on the outside of it's orbit.

Am I thinking about this right?

(Quantum Physics) Can we measure matter and energy of atomic and subatomic particles in 0 gravity? If so what has it proven?

How does shaving or not shaving affect long term facial hair growth?

How do patterns of shaving affect your facial hair? What about shaving against vs with "the grain"?

why is any molecule with carbon considered "organic"?

Posted: 03 Jan 2016 01:29 PM PST

what does this mean? why? i mean, shouldn't it be a requisite in order to be called organic to be related to biological or living organisms? how does carbon automatically make things organic?. And a plus question: Do any carbon containing molecules exist that are not organic? are pure carbon materials like graphene, graphite, diamonds, etc organic?

Would I be killed by the neutrinos from a nearby supernova?

Posted: 03 Jan 2016 01:49 PM PST

Neutrinos pass in enormous numbers through our bodies but they are incredibly unlikely to interact with matter. I read that in a supernova, 1046 joules of energy is released as neutrinos. If I was exposed to that kind of neutrino flux, disregarding any other radiation and particles, would I be harmed?

What does "Heisenberg's Uncertainty Principle" actually mean?

Posted: 03 Jan 2016 11:48 PM PST

My general approach while studying physics is by using my imagination but when it comes to Uncertainty Principle imagination seems to be limited. I know how it is defined and what is it's mathematical equation but if you could break it down for me in practical terms and why is it impossible to know the exact position and momentum(and velocity) of a moving particle, that would be very helpful.

Do babies smile when they're happy because of social conditioning or because its part of their biological programming?

Is it possible for animals to make sounds other than the ones they do? For example, could a cow say "milk" if it were trained to? Why don't animals make a variety of noises/why do they sound the way they do?

Sorry, I know this is a jumble of questions, but I just walked in on my sister-in-law asking her dog to say "I love you." I know the dog isn't going to say the words but... why not?

Why can't we add/multiply with big numbers easily?

Posted: 03 Jan 2016 01:31 PM PST

The computational power needed isn't much bigger than calculating with small numbers, right? I'm talking about the human brain btw, if that's not clear.

How does a tracker work?

Posted: 03 Jan 2016 03:04 PM PST

I am a complete beginner in how electronics work, and I was wondering if anyone can explain how a tracker works. Like those trackers that you attach to your phone and it notifies you where your phone is when you lose it.

Kepler is using the photon stream from the sun for stabilization. How much pressure does the photon stream exert using a unit of comparison we'd relate to?

How do ants coordinate digging/tunneling with one another?

Posted: 03 Jan 2016 08:34 AM PST

Can someone explain to me how ants coordinate making a tunnel/chamber system with one another? I am working on an ant behavior sim and for the life of me can't get them to create a tunnel system without cheating (adding behaviors that are too 'smart' for ants). I've managed to emulate foraging, caring for young, defense, etc. but tunnels still boggle me. Thank you!

How does adaptive radiation get its genetic variation?

Posted: 03 Jan 2016 04:20 PM PST

In adaptive radiation like the one that occurred with finch birds, the birds with beaks most suited for their food type survived and therefore many different kinds of birds were created from one starting type of bird. But how did these variations of birds of the same type of birds come about?

Were some birds simply born with mutated beaks by accident and then happened to thrive because the new availability of a niche resource? Or did the birds genes somehow remember that the bird before it struggled to eat hard seeds so evolution grants it with a stronger & bigger beak?

Do human proportions change as we grow due to the square-cube law?

Posted: 03 Jan 2016 03:33 PM PST

From my understanding the efficiency of a lot of human components, such as bones and muscles, are related to cross-sectional area rather than volume. Likewise, I assume that the efficiency of things like our intestines are related to surface area rather than volume.

Since both surface area and cross-sectional area grow at a quadratic rate while volume grows at a cubic one, does that mean our proportions change partially because we need to increase the areas of certain functional regions to match our overall body-volume?

If not, why do our proportions change?

Why is Brazil's northeast semi-arid?

Posted: 03 Jan 2016 06:11 AM PST

The Sertão is a (sub-)region in the northeast of Brazil that is known to have a semi-arid climate. How is this possible, when this region is so close to the equator and not nearly at a latitude where you would expect a desert?
