Studying Brownian Motion
- 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.
