Just how much does functional specialization within the brain vary across humans?

In recent decades, localization of different action and functions within specific brain regions has become more apparent. How much does this localization vary between people? I'm interested in learning more about the variance in the location as we as size of brain regions.

As a follow-up question, I would be very interested to learn what is known about variance of functional specialization in other animals as well.

How can we accurately measure happiness?

Posted: 22 Jul 2019 08:10 AM PDT

Happiness is such a subjective concept that has so many facets and factors. I was recently assigned to read the world happiness report, but self-reporting and 6 macro factors don't seem like an accurate way to quantify a qualitative variable. Is it even possible to quantify happiness?

What causes Jupiter's Auroras?

In many models, dark matter WIMPs are their own anti-particles. How are they expected to generate photons on annihilation if they have no coupling to the EM field?

How is humidity measured?

Posted: 21 Jul 2019 08:19 AM PDT

(I hope this is the proper flair).

Right now where I live, my weather app says it's 79% humidity. I know what humidity feels like and I know it has something to deal with moisture but how is it measured/converted into a percent. What would happen if 100% humidity were reached?

How would I go about testing a rock for its composition?

Posted: 21 Jul 2019 10:07 PM PDT

So me and my friends went camping, and found a large rock on the beach, it looks very out of place, much larger, smoother and less eroded than the other rocks around it, and it almost looks like someone has painted it. I know that its not paint because the rock is essentially in the middle of nowhere and the amount of paint it would take to cover the thing would be ridiculous, as well as it would be flaking off. I broke a small piece off, and it was really really hard, broke 3 rocks in half before getting a small chunk off of it. Out of curiosity I was wondering what its made of, would I have to send it to a spectrometer, or is there somewhere that does testing like this I can easily mail a piece to?

Are mammals born with the same number of nerve endings as an adult? Or do new ones grow as the animal grows?

What happens in the body when it "adjusts" or "acclimates" to higher altitude?

Posted: 21 Jul 2019 09:00 AM PDT

So, I've loaded up the whole fam damily and trees up into the mountains for vacation. We went from ~600ft elevation to almost 10,000 ft in two days. Needless to say, we're all a bit tingly and light headed. This was all expected. Everyone is saying, "you've just got to take it easy until you get acclimated. That got me wondering, what does the body do to acclimate itself?

Why does highway MPG decrease ~linearly with speed, when the power to overcome air drag goes up v^3?

Posted: 21 Jul 2019 07:07 AM PDT

You'd think engine efficiency is anywhere from around 40-50 mph, but the dropoff isn't that big. It's tiny (not even linear until >70mph) compared to v3. What gives?

Where is the Rosetta spacecraft now?

Posted: 21 Jul 2019 10:08 AM PDT

What happened to the Rosetta spacecraft which I believe landed on the comet it was aiming for in 2014? I think we lost communication with it but is it still on the surface of the comet? Where is the comet now?
