What is believed to be the smallest force ever measured, 42 yoctonewtons, has been detected by at the Lawrence Berkeley National Laboratory. A yoctonewton is one septillionth of a newton and there are approximately 3 x 1023 yoctonewtons in one ounce of force. That's tiny. Using a combination of lasers and a unique optical trapping system that provides a cloud of ultracold atoms, the researchers detected the minute force. read more
