A letter written by Albert Einstein in which he writes out his famous E = mc 2 equation has sold at auction for more than $1.2 million, about three times more than it was expected to get, Boston-based ...

An equation of the form \(y = mx + c\) where \(m\) and \(c\) are numbers, gives a straight line when values of \(x\) and corresponding values of \(y\) are plotted on a grid. A straight line is a ...

Identifying governing equations from observational data is crucial for understanding nonlinear physical systems but remains challenging due to the risk of overfitting. Here we introduce the Bi-Level ...

'I think of a number, add four, and the answer is seven.' Written algebraically, this statement is \(x + 4 = 7\), where \(x\) represents the number you thought of. \(x + 4 = 7\) is an example of an ...

A new cubic molecular-based equation of state (MMM) accurately calculates pressure, volume, temperature (PVT) and vapor-liquid equilibrium (VLE) data for pure and mixed fluids. Comparisons to the ...

Researchers who want to predict the behavior of systems governed by quantum mechanics—an electron in an atom, say, or a photon of light traveling through space—typically turn to the Schrödinger ...
