Whoa! I wasn’t ready for that!

Thanks for the ping.

The Uncertainty Principle

The position and momentum of a particle cannot be simultaneously measured with arbitrarily high precision. There is a minimum for the product of the uncertainties of these two measurements. There is likewise a minimum for the product of the uncertainties of the energy and time.

This is not a statement about the inaccuracy of measurement instruments, nor a reflection on the quality of experimental methods; it arises from the wave properties inherent in the quantum mechanical description of nature. Even with perfect instruments and technique, the uncertainty is inherent in the nature of things.

LOL... camera phones are amazing to me.

Actually, I’m pretty startled about this story. It was only ten years ago or so that a friend of mine was doing research with femtosecond pulses. I hadn’t realized the horizon has been pushed into the attosecond range already
