In October 2014, a few months out of college, I made my first web app so users could submit examples of constructions of upper bounds for a graph theory problem.
This last week, I've updated it to make it more mobile-friendly and colorful! Try it out and see if you can improve any of the bounds!

When Einstein proposed general relativity he laid out three tests: the precession of Mercury's perihelion, deflection of light by the sun, and gravitational redshift.
Irwin Shapiro proposed a fourth test #OTD in 1964: the gravitational time delay of light. 🧪 🔭 ⚛️

Quantum memory is crucial for quantum communication and computing. Until now, unruly noise forced quantum memories into a trade-off between efficiency and fidelity. The trade-off is resolved, potentially enabling advances in high-speed quantum technologies.
