My All-Time Favourite Kink Picture. Surprise

Science is cool. Understanding a bit of physics goes a long way to figure out the magic in floggers, whips and other lovely toys.

And I thought it stood for phunisment

The Big Bang Theory helped to boost the popularity of science, just like Star Trek before it. A number of cast member from the various Star Trek Franchises made guest appearances: George Takei, Will Wheaton, Levar Burton, Brent Spiner and the late Leonard Nimoy. Steve Wozniak, co-founder of Apple also appeared as did astronauts Buzz Aldrin - second human on the moon - and scientist and NASA astronaut Mike Massimino. Other scientists with a guest appearance on the show are Brian Greene, professor of string theoy (that one is for geeks only) as well as awesome  astrophysicist Neil deGrasse Tyson and finally physics professor Stephen Hawking, the only person Sheldon is afraid of, apart from his mum.

Now that we've established science is cool, and physics is even cooler, think back to secondary school:

Some have to think back a bit further than others so let me help you. Conservation of momentum means objects in motion, stay in motion, until they transfer their energy. No energy gets lost and without friction the movement goes on forever.

Some people--or were they simply lazy dommes?--thought it was so cool, they applied the momentum conservation principle to the training of their slave. Not sure it is a good idea but the picture below is definitely my all-time favourite kinky picture. Fortunately for the slave friction makes sure it does not go on forever.

Don't try this at home.

Oops, too late.
