The mathematician hopes this method will help students avoid memorizing obtuse formulas. His secret is in generalizing two roots together instead of keeping them as separate values. Quadratic ...

A mathematician at Carnegie Mellon University has developed an easier way to solve quadratic equations. The mathematician hopes this method will help students avoid memorizing obtuse formulas. His ...

The creator of Star Trek, the late Gene Roddenberry, has arrived in the form of a holographic, nervous, nebbish man, embodied by the usually heroic Anson Mount. Could Next Generation fans in the 1990s ...

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 ...

Abstract: Calculating the first-arrival traveltimes of quasi-compressional (qP) waves has important applications in geophysics. In practice, geophysical problems often involve extensive calculations ...

Quadratic functions are essential in the world of mathematics and have a wide range of applications in various fields, such as physics, engineering, and finance. An inverse function can be thought of ...
