Given the current state of practice and visions for the future (including AI), certain practices should be reevaluated. This ...

Physicists have identified a new superfluid phase in a class of quantum systems that, until recently, looked too unstable and ...

Abstract: In recent years, three-dimensional (3D) point clouds, which are applicable in various fields such as the metaverse and immersive communication, are attracting increasing attention. Under ...

It’s no secret that many of us are not too fond of mathematics and geometry, and that it is often too complex. But even so, it can be pretty mind-blowing to look back in history and discover the ...

With so many 3D design and modeling tools available, finding the right fit can be overwhelming. Enter BRL-CAD, an open-source, cross-platform software built on constructive solid geometry (CSG)—a ...

First let’s start with a very obvious question our students are going to have… What is geometry? Geometry is one of the oldest sciences and a branch of mathematics. It focuses on shapes and their ...

When we think of particles, we tend to think of them as real objects – tiny, point-like entities with definite properties such as position or speed. But particles are really just energetic spikes in ...

Physicists recently mapped the hidden shape that underlies the quantum behaviors of a crystal, using a new method that’s expected to become ubiquitous. Famously, at the quantum scale, particles can be ...

Can you chip in? As an independent nonprofit, the Internet Archive is fighting for universal access to quality information. We build and maintain all our own systems, but we don’t charge for access, ...

Discusses the properties and types of triangles, explaining that a triangle is a closed figure with three sides and angles. It categorizes triangles into equilateral, isosceles, scalene, obtuse, right ...
