The earliest scientists first observed the waves that earthquakes produce before they could accurately describe the nature of earthquakes or their fundamental causes, as discussed in Lessons 1–5.

Physics fans are a lot like surfers. Both think waves are really fun. For surfers, it’s all about having a good time. For physicists, it’s about understanding some of nature’s most important physical ...

Eight days ago, it rained over the western Pacific Ocean near Japan. There was nothing especially remarkable about this rain event, yet it made big waves twice. First, it disturbed the atmosphere in ...

Multichannel recording technologies have revealed travelling waves of neural activity in multiple sensory, motor and cognitive systems. These waves can be spontaneously generated by recurrent circuits ...

Each image was processed and projected, and the 0.5 μμm wavelength was selected to detect the wave packets. Images A, B, D, F, and G are at Ls≈150°; Image C at Ls≈285°; Image E at Ls≈245°. Image G is ...

This 2D example can be extended to a 3D situation, where waves are spherical and refocus exactly at the center of the sphere. However, in real life, one generally focuses light from one side, along ...

Two weeks before Christmas in 1978, the cargo ship MS München encountered a fierce storm in the North Atlantic. Although the captain couldn’t evade it, the forecasted waves and winds should have posed ...

Decades ago physicists realized that gravitational waves are no mere passing phenomenon. Instead those ripples in space should leave behind permanent marks: a fixed distortion in their wake. So far ...

First, let me plead, “Mea culpa.” I’ll admit to fixating on marine wind forecasts before venturing out to sea, sometimes to the exclusion of wave projections. That shortcut has more than once come ...
