This persnickety number determines the strength of magnetic fields. It figures in everything from motors and generators to audio speakers. Oh, and without it we’d live in eternal darkness.

Planck's constant reveals the quantum world's fundamental energy levels. It shows how light and matter exist in discrete units (quanta). This constant defines limits to our knowledge of particle ...

Not all intervals are created equal, even if the average wattage is kept similar. Making intervals that vary in intensity can make them really different from constant wattage intervals. Tough short ...

Ever wonder why Java's const keyword is unimplemented? More specifically, why do we mark global constants in Java with both the static and final keywords? Why are Java constants static and final? The ...

We know that the universe is getting bigger. And we know that the speed that the universe is getting bigger is also getting bigger. The standard assumption is that the acceleration rate is itself ...

Researchers suggesting that the speed of light varies have come up with a numerical prediction that will allow their theory to be tested. Many theories in physics are built upon the idea that the ...

The keywords const, readonly, and static are used often when programming in C#. However, while these keywords have important differences, they also have similarities that sometimes make it hard to ...
