Yes, dopamine is evolution's way of encouraging us to not die off as a species. So, too, is epinephrine. Dopamine is a poor end in itslef, though. Take away evolution's carrot by giving everyone carrots, and all evolution has left is the stick.

Some folk at NASA have attempted to create a 10mm warp bubble with a 1:10,000,000 space-time purturbance. (They were trying to get half of a split laser beam to hit an interferometer sooner than the other by reducing it path length by one micrometer via space warp.) Results of the experiment were inconclusive.

Hi. I'm an ameture blacksmith and have been studying metallurgy for the past couple decades in an attempt to make better tools next year than the ones I made last year. There's one thing keeps eluding me... I'm hoping someone here can point me in the right direction or adjust my world-view. According to all of the books, carbon atoms are supposed to be able to fit into the interstitial space in the middle of an austenite crystal cell. This is an FCC cell, so the biggest interstitial should be equal to 0.414 times the atom diameter. I find iron diameter numbers ranging from 248 pm to 280 pm. This would give interstitials ranging from a bit less than 103 pm to just under 116 pm. But the carbon atom sizes I'm finding numbers for are 134 pm to 154 pm in diameter. How do they fit in there? And, for that matter, how do they squeze in there after the carbides dissolve anyway?
