Page: Feed: --- ## [The Euclidean Algorithm: Curiosity Satisfied – Sadly](https://jrh794.wordpress.com/2026/06/03/the-euclidean-algorithm-curiosity-satisfied-sadly/) _2026-06-03 · jrh794 · Math Thoughts_ The Euclidean Algorithm is a (the) way of finding a common factor between two numbers, say a and b. The method is to divide the smaller number into the larger and then divide the remainder into the smaller and continue Continue reading ## [Packing Circles with Unequal Radii – Stacking Corks Edition](https://jrh794.wordpress.com/2026/01/19/packing-circles-with-unequal-radii-stacking-corks-edition/) _2026-01-19 · jrh794 · Math Thoughts_ A part of my wine cork construction project, a few years, was a trivet out of wine corks. Here it is. It is wonderfully light and holds hot dishes well away from the table. Looking directly down on it, one Continue reading ## [A Mathematician Slices Carrots – Part IV](https://jrh794.wordpress.com/2025/06/23/a-mathematician-slices-carrots-part-iv/) _2025-06-23 · jrh794 · Math Thoughts_ This post shows all the calculations I needed for getting equal total surface areas including the derivation of the surface area of an oblique cone using double integral calculus. I am still using OneNote for graphs and formulas, hence this Continue reading ## [A Mathematician Slices Carrots – Part III](https://jrh794.wordpress.com/2025/04/14/a-mathematician-slices-carrots-part-iii/) _2025-04-14 · jrh794 · Math Thoughts_ I want to slice carrots for a salad. I have a conical carrot and a blue cutting board and an invisible knife. I could choose to make all the slices (slicing perpendicular to the cone s axis) the same thickness. But Continue reading ## [A Mathematician Slices Carrots – Part II](https://jrh794.wordpress.com/2025/02/19/a-mathematician-slices-carrots-part-ii/) _2025-02-19 · jrh794 · Math Thoughts_ This post shows a derivation of the volume of an oblique cone using pure geometry. I am still using OneNote for graphs and formulas, hence this PDF. ## [A Mathematician Slices Carrots – Part I](https://jrh794.wordpress.com/2025/02/06/a-mathematician-slices-carrots-part-i/) _2025-02-06 · jrh794 · Math Thoughts_ I want to slice carrots for a salad.
