With beautiful afternoon daylight, a brain freshly loaded with spherical harmonics, a vial of soap water, and a powerful lens, I ran behind bubbles and attempted to zoom in on their exquisite optical details. Multibubble Thin Film Pattern Details Whand A Whand B Whand C Whand A' Hand
How Euler Tackled an innocent-looking integral
For unclear reasons, I really wanted to write down one wacky (read: elegant) calculus exercise tonight -- have you integrated the cotangent function twice? I feel the infinite series are mere toys dancing at the fingertips of Euler, and consider his method to tackle this quite beautiful, my usual attitude towards Euler math. For some … Continue reading How Euler Tackled an innocent-looking integral

Iridium Point Goes to 1st International Symposium on Quantum Computing and Musical Creativity
Well, Y. F. Wang, PhD student at the Auckland U’s physics department is going. I don’t think my (computational) musical misadventures deserve any recognitions yet. This Event is hosted by University of Plymouth in late November, and features many downstream Quantum info professionals at places such as Cambridge Quantum Computing Lab and IBM. My notes … Continue reading Iridium Point Goes to 1st International Symposium on Quantum Computing and Musical Creativity

All Legal combinations of digits For the 24 Game
The rules of our 24 game are based on the original card game, and quite simple: Take 4 integers between 0 and 9, and by joining them with parentheses () and the 4 arithmetic symbols (+,-,×,÷) only, formulate an equation that gives 24. My mother and I used to compete and see who could work … Continue reading All Legal combinations of digits For the 24 Game
