Welcome


The title says it all: this blog features physics videos found everywhere on the web: animations, demonstrations, lectures, documentaries.
Please go here if you want to suggest other nice physics videos, and here if I mistakingly infringed your copyrights. If you understand French, you'll find a huge selection of physics videos in French in my other blog Vidéos de Physique.

The same explanation works for what role the speaker plays in moving objects/bottles using sound, the acoustic propulsion in one of my other videos below. This also explains a bit about resonant frequency and compares the sound wave compression and decompression to an oscillating spring, a simple harmonic oscillator.

ScienceCasts: A Sudden Multiplication of Planets

This week, NASA announced a breakthrough addition to the catalog of new planets. Researchers using Kepler have confirmed 715 new worlds, almost quadrupling the number of planets previously confirmed by the planet-hunting spacecraft. Some of the new worlds are similar in size to Earth and orbit in the habitable zone of their parent stars.
