Want to master the concept of velocity in physics or engineering? This video breaks down how to calculate and understand velocity using numerical derivatives. We explain step by step how to ...

With clocks, we measure the numerical order of a material change, i.e., motion running in space. There is no experimental evidence that clocks measure time. It is convenient to replace the concept of ...

Using a numerical model that simulates ocean currents, researchers are shedding light on the important ''motion of the ocean'' in the Straits of Florida. They have conducted a first-of-its-kind study ...
