Then we spoke about mathematics..

Andy loves cycling and mathematics. So much so that he had this tattooed by Jase of Art ‘n’ Soul Tattoo in Devon, England, and by the looks of things he cycled home after the tattoo session. Now that’s dedication!

It’s the bicycle power formula, it describes the various forces against which I’ve battled for pretty much every week of the last quarter century!

  1. i like the thing.

    other then that it’s an okay tattoo i guess, if you’re into that sort of thing. i personally dont like math and don’t find the appeal of having a mathematic formula tattooed onto me.

  2. As a cyclist meself, I’m lovin’ this. I fancy getting a tattoo of that oily chain mark you get on the inside of your right calf on summer rides when not paying attention…

  3. I think this is a really cool choice of tattoo!! And yeah… obviously he *is* into that sort of thing or he wouldn’t have gotten the tattoo and I think the appeal (to him) is obvious even from the minimal information supplied O_O

  4. I’ve done a bunch of bike tattoos, they’re usually pretty dedicated people. Now if I can just find more time to get on my Specialized Hard Rock, & work on this tattoo guy physique, that would be good,…

  5. Crankset? Crankset? He’s on a Mercian, and you’re noticing the crankset? Tch! That’s a beautiful frame!

    Krys – the oily mark you refer to is usually known as a “chainring tattoo”. 😉

  6. I’m seeing what looks like a pennyfarthing wheel in the backround, awesome tattoo and bike he’s on but penny farthings’ eclipse everything elses cool factor

  7. Im currently studying very basic mechanics and Id quite like to get to understand this formula, I can follow some variables but others have me curious =]

  8. Jack – I was trying to figure out what frame he was on. Knew from the Reynolds sticker that it must be decent, but never thought to look behind his leg at the downtube.


  9. I’ts actually a physics formula, and yes physics and math overlap, but you would never learn this in a math class. It’s basic dynamics physics.

  10. Sarita – check out the Bicycle Performance page on Wikipedia for the details. Basically there are two chunks of resistance, the linear chunk, which is proportional to friction, gradient and groundspeed, and the non-linear chunk which brings in the square of windspeed. At some point around 17-19 mph, the non-linear part becomes the major force, which is why it’s easy to go slow and really hard to go really really fast.

    And yeah, that’s a pennyfarthing. He’s called Bucephalus. Hope to do a century ride on him this summer…
