Most trigonometry students look at triangles on a flat surface. However, people from ancient astronomers to modern navigators calculated the arc lengths and angles of triangles on a sphere. They used ...

The Riemann Hypothesis is widely regarded as the most important unsolved problem in mathematics. Put forward by Bernhard Riemann in 1859, it concerns the positions of the zeros of the Riemann zeta ...

One of the most significant of these questions is the Riemann hypothesis. At its core, the Riemann hypothesis seeks to find and study the pattern and distribution of prime numbers as they get larger ...

The Sphere function has d local minima except for the global one. It is continuous, convex and unimodal. The plot shows its two-dimensional form. The function is usually evaluated on the hypercube x i ...

[DaveMakesStuff] demonstrates a great technique for 3D printing a sphere; a troublesome shape for filament-based printers to handle. As a bonus, it uses a minimum of filament. His ideas can be ...

Prime numbers are beautiful, mysterious, and beguiling mathematical objects. The mathematician Bernhard Riemann made a celebrated conjecture about primes in 1859, the so-called Riemann Hypothesis, ...

Now that's a big "I Voted" sticker. Recently seen on the exosphere, or outer shell, of Sphere, the mammoth multimedia destination in Las Vegas: a bright yellow face with an "I Voted" sticker.

Las Vegas won’t be the only city with a giant, glowing Sphere. Abu Dhabi is set to become the next location to showcase multimedia entertainment in the unique spherical structure, the Sphere ...

The world’s second Sphere is headed to Abu Dhabi, after the opening of the first giant dome entertainment complex in Las Vegas in September 2023 with a residency by rock band U2. Abu Dhabi's ...
