There are plenty of ways to get out of a traffic ticket: charm, flattery, fakery, full-on tears, "My uncle is a cop" all come to mind. Submitting a four-page paper with math equations and graphs proving that your traffic violation was the result of the officer suffering from an optical illusion isn't the strategy most people would employ. It worked, though. In his paper "The Proof of Innocence" Dmitri Krioukov, a physicist at the University of California in San Diego, outlined for a judge the mathematical reasons why he was not guilty of running a stop sign. In making his case, Krioukov wrote that a police officer can perceive a car as not having stopped -- even though it really did stop -- if three different criteria are met:.

With all of the PhDs America produces, pretty soon law enforcement will be limited to officers with graduate degrees in quantum physics - but for now, Newton is still all it takes. Well, usually. Sometimes even the laws of physics are not what they look like. And special laws of physics apply on April 1st so use the contents of this paper on the differences between angular and linear motion carefully.

Not every judge is going to be impressed but this was in California, so he was probably happy to have someone besides an environmental activist in court.

What were the combined events that led to the distortion of reality? The officer was measuring the linear but not angular speed of his car, the car decelerated and then accelerated relatively fast and finally, that another momentarily blocked the officer's view.

Bring on the graphs! Krioukov told Physics Central he did. If you believe that, you'll believe I can use math to show you how to get to all of the good hookers before Charlie Sheen - and we know that just isn't possible. Science 2. About I founded Science 2. View Profile.

Bet it's a painful memory, isn't it? Dmitri Krioukov, a physicist at the University of California, San Diego, was pulled over for jumping a stop sign. But Krioukov tried something that most traffic courts probably haven't seen: He wrote an academic paper to argue why he ought to be found not guilty. Its title: " The Proof of Innocence. The judge bought it, says Krioukov. He was acquitted.


Physicist Dmitri Krioukov uses math paper to get out of traffic ticket

He went to court to argue the ticket, armed with a scientific paper that mathematically demonstrated that he really had stopped. He won. Krioukov has since posted the entire paper, rather immodestly called "The Proof of Innocence", on the arXiv server. It's probably debatable how much his ironclad mathematical reasoning really helped determine his innocence - it's just as likely the judge threw out the ticket when it was demonstrated another car had obstructed the ticketing police officer's view. Still, let's take a look at one of science's most audacious papers, albeit a fairly mundane sort of audacity:. We show that if a car stops at a stop sign, an observer, e. So then, according to Krioukov, this triple coincidence created the illusion that the car had never stopped.


Dmitri Krioukov, Physicist, Writes Four Page Paper To Avoid Paying Traffic Ticket

Dmitri Krioukov, a senior research scientist at UCSD, successfully appealed his failure-to-stop ticket using a physics and math argument that ultimately swayed a San Diego judge. Krioukov compared the problem to the way a person standing on the platform sees a train approaching and thinks it is moving slowly, when in fact it is barreling down the track. Krioukov determined that a car moving at a constant speed can appear to move in the same way as a car that is moving fast but stops for a short time and then accelerates. In other words, a car that appears to be moving at a constant speed through a stop sign could have actually stopped before speeding up again. He said the calculations took him five to 10 minutes, but writing the paper took a few hours.


Physicist Beats Traffic Ticket With Mathematical Paper

A physicist at the San Diego Supercomputer Center at UC San Diego used his knowledge of measuring bodies in motion to show in court why he couldn't be guilty of a ticket for failing to halt at a stop sign. If you want to use this excuse, you'll have to learn a little math -- and some powers of persuasion. Krioukov claims he was approaching a stop sign in his Toyota Yaris when a police officer saw him roll through the intersection, apparently without stopping, and pulled him over. Case closed — except that Krioukov says he was able to show a confluence of events that only made it seem he hadn't stopped. First, the officer watching the stop sign saw Krioukov's car from the side, distorting his idea of how fast Krioukov was traveling before the stop.
