Julius Sumner Miller: Lesson 13 - Archimedes' Principle

If a body is submerged in a fluid - a liquid or a gas - the body is buoyed up -lifted up - by a force equal to the weight of the fluid displaced. This is the Classic Principle of Archimedes. We show an array of DEMONSTRATIONS bearing on this Principle. A - We weigh a body on a spr

Theodora Bourni: Ancient solutions of mean curvature flow

Abstract: Ancient solutions, which are solutions that have existed for all times in the past, are of interest in the study of geometric flows as they model singularities of the flows. In this talk we will present some recent developments concerning convex ancient solutions. The main focus

Areas and volumes for a sphere | Universal Hyperbolic Geometry 35 | NJ Wildberger

The beautiful formulas for the surface area and volume of a sphere go back to Archimedes, who also discovered some other remarkable facts relating spheres to circumscribing cylinders. We describe these results. Then we introduce rational turn angles---a renormalization of the notion of an

A cube is used as a fair die of 6 faces. However, there are many dice of different shapes on the market. To make them fair, most of them usually have some symmetric shapes. I classify these variants of dice on the market into two groups. First, let's consider that a sphere as a model of a
