Body mass index, or BMI for short, is a measure of body weight based on your height. For decades, BMI has been a way to measure whether someone is at a healthy weight. In general, people are ...

They find that extremely low angles of approach are not necessary to produce an elliptical impact. Furthermore, they show that impacts at plausible velocities of 6 to 10 km s −1 do not generate so ...

Abstract: Staircase approximation in the simulation of the arbitrarily irregular surface will cause artificial interference of wavefield. The body-fit coordinate transformation can accurately simulate ...

Abstract: In 1960, three years before receiving the Nobel Prize in Physics, Hungarian-born American theoretical physicist and mathematician Eugene Wigner (1902-1995) published a paper, ?The ...

In a previous paper, we have mathematically derived the Schrödinger equation using the construct of a Characteristic Function. We have shown that this derivation has a great number of consequences and ...

Recently, there has appeared a new type of evaluating partial differential equations with Volterra integral operators in various practical areas. Such equations possess new physical and mathematical ...

On the night of Oct. 5, 1923, Edwin Hubble observed a strange star that flickered in intensity at regular intervals. The star ...

In the 30 years since the discovery of 51 Pegasi b, more than 6,000 planets outside our Solar System have been catalogued. Two modern-day explorers explain how.

On Feb. 17, 2026, an annular solar eclipse will be visible from a remote part of Antarctica, forming a "ring of fire" for up ...

It might seem unfathomable to us living today, but 179 years ago on this very date, our galaxy, The Milky Way, actually grew ...

Adam Hayes, Ph.D., CFA, is a financial writer with 15+ years Wall Street experience as a derivatives trader. Besides his extensive derivative trading expertise, Adam is an expert in economics and ...

The book is devoted to boundary value problems for general partial differential equations. Efficient methods of resolution of boundary value problems for elliptic equations, based on the theory of ...
