SAN DIEGO, Calif. — Science does matter. That was the opinion of a California judge after a UC San Diego college profesor presented a scientific defense.

Dmitri Krioukov, a Russian researcher and Internet data analysis professor, wrote a four-page rebuttal paper explaining how the laws of physics distorted the cop's perception, causing him to misperceive the professor rolling through a stop sign.

The paper even had charts showing how physics prevented the cop from correctly evaluating what he saw. The paper explained the differences between linear and angular motion and demonstrated how the professor theoretically came to a complete stop. He then reaccelerated — from between 22 mph and 0 mph and then from 0 mph to 22 mph — all in a three-second span of time.

During those three seconds, the professor was passed by another vehicle that shielded the cop’s vision and prevented him from adequately seeing what actually happened before he pulled him over.

The judge probably didn’t completely buy the professors story, but his presentation was clear and understandable enough to cause the judge to doubt the cop’s simple explanation. The judge declared the professor innocent and the $400 fine was dismissed.

Now the professor has become a cause celebre in physics and mathematics circles and is overwhelmed with people giving him kudos and asking for his help in beating other traffic tickets.
