Google is Freaking Me Out!

Ever heard of optical tweezers? Yeah, me neither until my wife built a set in her lab. The latest round of ads on my gmail sidebar included "Building Optical Tweezers? Single Frequency blah blah blah is just what you need!" I've never e-mailed my wife about optical tweezers, I've never sent or received any e-mail about optical tweezers and there it is, in my side bar. The advertisement that should have been sent to my wife.
