To bridge the gap between Einstein's curved spacetime and the discrete jumps of quantum spin, you have to look under the hood of how continuous symmetry works. The secret to quantum gravity lies in a 19th-century algebraic code: Lie Theory.
For nearly a century, physicists have struggled to unify Einstein's smooth fabric of spacetime with the discrete jumps of quantum mechanics. Here is a journey through the four monumental contributions of Abhay Ashtekar, the pioneer who rewired the math of general relativity and made modern quantum gravity possible.
After wrestling with Node.js memory limits and aggressive CSS resets, this site now natively supports lightning-fast, zero-client-JS mathematical typesetting. Here is how I did it, and why beautiful equations matter.
We finally killed the long-lived developer API key, a massive victory for open-source security. But as NDSS 2026 and USENIX Enigma '25 revealed, attackers haven't given up—they've just moved to our build pipelines and flooded our vulnerability data. Here is what we must do next.
I take a look at the history of measuring time—from sand glasses to atomic clocks—and explain the clever physics behind using a smartphone speaker to force a digital wall clock to sync with the Internet's exact time.
