Surprisingly, we found the structure to be doubly ring-slipped," says Takebayashi. Ring-slippage happens when the number of atoms in…...

1+ week, 12+ hour ago  (1134+ words) I get irritated when somebody multiplies two numbers and gets the wrong answer, and then says, "I'm bad at math." "That's an overstatement that gives them undeserved status. They are bad at arithmetic, which is a very specialized area of…...
