math prof In that case, a category theorist is one who can see analogies between analogies (i.e. natural transformations between functors)

Nobel laureate Steven Weinberg on old math being applied in physics: "There is a spooky quality about the ability of mathematicians to get there ahead of physicists. It's as if when Neil Armstrong first landed on the moon he found in the lunar dust the footsteps of Jules Verne"

Guardian Environment I attended a lecture by famed archeologist Lewis Leakey once and the thesis of his talk was species go extinct because they overspecialize and unable to adapt. His concluding remark was humans will go extinct due to overspecialized brains. (I think I know what he meant.)

"The Earth is a very small stage in a vast cosmic arena. Think of the rivers of blood spilled by all those generals and emperors so that, in glory and triumph, they could become the momentary masters of a fraction of a dot." --Carl Sagan, born OTD 1934

This is why we think there's a black hole in middle of our galaxy: the orbits of the stars around the center of the Milky Way buff.ly/2n3zjKu

Our posturings, our imagined self-importance, the delusion that we have some privileged position in the Universe, are challenged by this point of pale light. To me, it underscores our responsibility to deal more kindly with one another youtu.be/GO5FwsblpT8 #WorldKindnessDay

Peter Shor's comment: "So the only advice I have is that more physicists need to not worry about grants, and go hide in their attics and work on new and crazy theories, the way Andrew Wiles worked on Fermat's Last Theorem." 🙌🙌

Peter Shor on how he discovered his quantum factoring algorithm: "I didn't tell anybody I was working on it until I had figured it out... I thought about it on and off for maybe a year... So, people, go hide in your attics!" backreaction.blogspot.com/2018/11/the-pr…

Mathematics should be written to be accessible to the largest number of people, which is why it is important to write mathematics in the most general, categorical language.

• Never stop learning. • See failure as a beginning. • Teach others what you know. • Assume nothing, question everything. • Analyze objectively. • Practice humility. • Respect constructive criticism. • Love what you do. • Give credit where it's due. • Take initiative.

In 1957, John Conway built a water computer called WINNIE (Water Initiated Numerical Number Integrating Engine)
