Conway was an active researcher and a fixture in the Princeton math department common room well into his 70s. A major stroke two years ago, however, consigned him to a nursing home. His former colleagues, including Kochen, saw him there regularly until the COVID-19 pandemic made such visits impossible. Kochen continued to talk to him on the phone through the winter, including a final conversation about two weeks before Conway died.
“He didn’t like the fact that he couldn’t get any visitors, and he talked about that damn virus. And in fact, that damn virus did get him,” Kochen said.
Is there a characterization of the points 'inside' a triangle ABC in the Euclidean plane.
Express the vector to P as a linear combination P = xA + yB + zC
of those to A,B,C, with the side condition x + y + z = 1.
Then P is inside the triangle just if x,y,z are positive.

"any" is a dangerous word in mathematics - I can't tell whether it here means "some" or "every".
