Microscopy around the Home: Studying Brownian Motion Feature Summary

Type:
Physics in Your World
Title:
Studying Brownian Motion
Description:
Click on the photo above to see a video of Brownian motion--the random jiggling of small particles due to molecular bombardment--in this case, the particles are fat globules in diluted milk.  You can also see this higher-res video.

To find out how a physicist stopped Brownian motion in its tracks, check out Hold Still, from the American Physical Society's Physical Review Focus.
