An algebraic equation contains one or more letters in it. Each letter in the equation is called a variable. A variable can change in value. We guess at different values for each letter until our ...

Simultaneous equations are two linear equations that can be solved using bar models. By remembering that the same letter will always have the same value we can work out the missing values. To solve ...

In 1945, as the first atomic bomb exploded in the New Mexico desert, Enrico Fermi stood miles away, holding a few scraps of paper. As the shockwave rolled toward him, he dropped the papers and watched ...

Abstract: Reachability analysis is a powerful tool to analyze the behavior of dynamical systems. Typically, these tools are used to evaluate whether the dynamics of a system beginning from some ...

Abstract: The phenomenon of low-frequency breakdown in the electric field integral equation (EFIE) occurs when the wavelength of the electromagnetic wave is much larger than the size of the targets or ...

A simple looking grade-school math problem has stumped the masses. Can you solve it correctly? The simple equation shared by @BholanathDutta on X this week, who regularly posts brainteasers, read ...
