New Study: Some Sciences Really Are Better Than Others
By David Berreby from Big Think.
"If you want to rile up a biologist and have no pointed stick handy, try

standards of one science to judge another," she might say. "Physics is different from biology, not better."

which some meet better than others do. You're now set up for a
seemingly unresolvable philosophical debate. Most working scientists I
know would rather face the pointiest of sticks."
