Why We'll Never Build a Perfect Clock
We can make clocks that keep accurate time for millions of years. We can also make clocks with such high resolution they tick one billion billion times per second. So why can't we make a clock that does both?

Did We Find Longitude Thanks To A...Clock?
The equator is a clear and accurate line around Earth that makes measuring latitude a precise science, but when it came to figuring out how to do that with longitude, British sailors were at a loss. Until they devised a competition....

Internal Energy
In this video Paul Andersen explains how the internal energy of a system can change as the internal structure of the system changes. An object model will not be able to account for the restoring forces and so a system model must be used....

Who decides how long a second is? | John Kitching
In 1967, researchers gathered to answer a long-running scientific question: just how long is a second? It might seem obvious at first. A second is the tick of a clock, the swing of a pendulum, the time it takes to count to one. But how...
