SRINAGAR: The Department of Civil Engineering and Department of Mathematics at the National Institute of Technology (NIT) Srinagar on Monday jointly organised a guest lecture on “Advances in Computational Fluid Dynamics: From Mesoscale Modelling to Real-World Engineering Applications”. The lecture…
Mathematics is one of the subjects that becomes a bottleneck for liberal arts students. The approach for the Common Test for Mathematics is not the same as the one used for individual university entrance exams or secondary exams. The Common…
The previous two posts have been about polar triangles. The first used a polar triangle to derive a theorem, and the second showed how to compute polars using linear algebra. But what exactly is a polar triangle and why is…
Eight beads, each locked in its own straight slot. Push one and all eight roll around the dial as a perfect circle. This is the Tusi couple, found by the Persian astronomer Nasir al-Din al-Tusi in 1247, and it takes surprisingly…
Kourkoutis Lena Kourkoutis, assistant professor of applied and engineering physics, has received a Packard Fellowship for Science and Engineering from the David and Lucile Packard Foundation. The five-year, $875,000 award has gone to 18 of the nation’s most innovative early-career scientists and…
Last week a short email arrived: an open archive for AI-assisted mathematics had found my preprint and invited me to publish it there. This post is the route from a failed framework to that archive, and what I chose not…
A flexi toy is a chain of segments where each one holds a captive ball joint. You can generate the whole chain from a short Python script with manifold3d, so the same script makes a dragon, a snake or a centipede…
Escher's Circle Limit prints show a hyperbolic tiling squeezed into a disc, with tiles shrinking toward the rim. The maths is short: a tile edge is a circle that meets the unit circle at right angles, and the next tile…
Topics: Staff, Array, Two Pointers, Matrix, Biweekly Contest 52 You are given an m x n matrix of characters box representing a side-view of a box. Each cell of the box is one of the following: The box is rotated 90 degrees…
Hello! This is Vicky. I haven't really made videos or articles about my specialty, 'arithmetic,' very often, but today I've decided to take the plunge and talk about a core arithmetic theme, specifically 'teaching geometry.' There are so many arithmetic…
