For many, the phrase “quadratic equation” brings back memories of high school algebra classes and a tangled mess of variables and numbers. Yet, this fundamental mathematical concept is a powerful tool ...

Rewrite \(y = {x^2} - 6x + 11\) in the form \(y = {(x - b)^2} + c\). To get \(b\) (the number inside the bracket), halve the coefficient (number in front) of the second term in the original equation.

New studies of the “platypus of materials” help explain how their atoms arrange themselves into orderly, but nonrepeating, ...

Making electrons flow like a liquid is difficult, but inside graphene researchers forced them to move so fast that they ...

Differential equations are fundamental tools in physics: they are used to describe phenomena ranging from fluid dynamics to general relativity. But when these equations become stiff (i.e. they involve ...

Abstract: This paper presents a new active capacitor voltage balancing control method for the flying capacitor multicell (FCM) converters which is fully implemented using logic-form equations. The ...

Abstract: This paper provides a significant improvement to the coaxial-line equation that is used for analytical estimation of via capacitance in multilayered printed circuit boards (PCBs) Previously, ...

An authorised reissue of the long out of print classic textbook, Advanced Calculus by the late Dr Lynn Loomis and Dr Shlomo Sternberg both of Harvard University has been a revered but hard to find ...

"Worker voice: What it is, what it is not, and why it matters" The term “worker voice” has been used by practitioners, policymakers, and scholars to cover a broad range of institutions and mechanisms, ...
