If you’re studying for the higher tier exam, you will need to be familiar with calculations involving very large and very small numbers by using the ×10x or EXP button on your calculator. The equation ...

The wave equation is a very important formula that is often used to help us describe waves in more detail. It should be noted that some particular waves have their own specific speeds. The speed of ...

Researchers found that estimated Pulse Wave Velocity (ePWV), a readily available marker of arterial stiffness, has been shown to be an effective addition in identifying patients at risk of mortality ...

Since the aorta is the major component of arterial elasticity, the carotid-femoral PWV offers the simplest reproducible and noninvasive evaluation of regional stiffness. This measurement allows the ...

I love using seemingly random data to figure out stuff I wouldn't otherwise know. You can do this with all kinds of things, but in this example, I use video that I recorded from an airplane to figure ...

The universal speed limit of any kind of wave – be it electromagnetic or gravitational – travelling through a vacuum has been known since Albert Einstein developed his theory of special relativity in ...
