Sometimes, there are too many choices in this world. My benchtop function generator can output a sine, square, or saw wave anywhere from 0.01 Hz up to 60 MHz? Way too many choices. At least, that’s ...

Power cuts can strike at the most inconvenient times. From your refrigerator suddenly shutting off to your computer screen going black, an outage can cause frustration and even damage. This is where ...

Sine die is Latin for “without a day.” It is used to mean adjournment when no further proceedings of a meeting are scheduled. So when the 2025 Legislature adjourned sine die late Friday, that means it ...

All the tech we rely on, from cars to smartphones, was engineered using physics. You don’t need to know the science to use these things. But a well-rounded human should understand at least some of the ...

Everyone interested in analog electronics should find some value in this post. Of course, an effort has been made here to make the content understandable to relative newbies. Forget about complex ...

Abstract: We propose a method to solve differential problems, and in particular quantum wave equations, with periodic boundary conditions, in the direct space using periodic repetitions of the ...

It is possible to create traveling wave type solutions (and in particular soliton solutions) of partial differential equations by means of connections defining the representations of zero curvature.

To mathematicians, equations are art. Just as many are moved by a painting or piece of music, to those who appreciate and understand math, expressions of numbers, variables, operations and relations ...
