Today I learned there are only two known polyhedra in which each face shares an edge with every other face. One of them being the timeless beauty of the tetrahedron and the other one being whatever the heck this is

"NSF plans to claw back around US$500 million that has already been distributed to grant-making divisions. That money would be withdrawn from three of the NSF’s eight main areas, or directorates: engineering; computer and information science and engineering; and mathematical and physical science."

Harriet Brooks was one of Canada's first female nuclear physicists. Sir Ernest Rutherford said she was an equal of Marie Curie. She co-discovered radon and helped lay the foundations of nuclear science. Then she left her career when she was 29. This is her story. 🧵 1/12

Her hair is light-colored, loosely styled and swept back from her forehead. She wears a high-collared dark dress with a fitted neck and smooth fabric. The background is plain and light, with no visible objects or decorations.

Adding polymers to a liquid speeds up its flow through a pipe by reducing the frictional drag at the pipe’s inner surface. Now researchers have found that the polymers also suppress eddy formation and thus reduce the loss of flow energy to heat.

Polymers Tame Turbulent Flow
New experiments show that adding polymers to a fluid can reduce energy dissipation by suppressing small eddies.
