Tuesday Physics Tattoo : Blackhole Tattoo



Not 100% accurate as a blackhole, but I think it captures the concept.

Pretty accurate H2O tattoo


Hydrogen: one proton, one electron – check;

Oxygen (atomic number 8, atomic mass 16): you can see about 5 protons and 5 neutron, which is about right – you see half of the total from one side – check, two electrons in the s orbit of oxygen – check,

total eight electrons attributable to Oxygen and two for two hydrogen – check,

you see the molecular bonding between hydrogen and oxygen atoms – check, positioning of the hydrogen relative to oxygen – check,

wave-particle duality and localization stuff – not so perfect, but at least there is some fuzzy stuff there,

hydrogen shown as a perfect circle even in the presence of an Oxygen atom that it is bonding with, not perfect but hard to complain about it in light of other stuff that is right.

Enjoying a career measuring and predicting stream flow I spend a lot of time in, over and around water. I thought a tat of a water molecule would be just the thing. Talented tattoo artist Rose helped with advice and skill to make my first tattoo an enjoyable experience

Tuesday Tattoo: Magazine Tattoo


No, this is not photoshopped.

Marc Strömberg is a 22-year-old graphic designer in Ume, Sweden, and his leg is still sore. He creates record sleeves and posters for bands, and in his spare time he runs his own magazine, Tare Lugnt. Instead of publishing the latest edition in traditional paper and ink, he has had issue three entirely tattooed onto his left leg. The leg has now been photographed, and large-scale prints are due to go on display in Göteborg and Stockholm this month.

I don’t think I will ever remove a tattoo. Like I said, every tattoo is like a journal entry, and it represents different periods and places in my life.

Tuesday Physics Tattoo: Pi Day edition

This is a remarkable tattoo of the Basel equation and Pi.

I wanted to post this tattoo in the Pi edition to show that the magical number Pi appears at the strangest of places. One would not have expected the summation of inverse squares of integers to add up to some combination related to Pi, but here it is.



This little baby is also due to Euler. In 1644 Mengoli asked if anyone could find a closed-form value (and prove it rigorously) for the infinite sum of the reciprocals of the squares. So, what is 1+1/4+1/9+1/16……. and so forth off to infinity. Contrary to intuition this series does not diverge to infinity. Although we are adding infinitely-many positive amounts together we still get a finite number. This is because the positive amounts that we are adding are getting smaller sufficiently fast. It was known that this sum was approximately 1.644. However, when Mengoli asked for a closed-form value he was looking for an EXACT expression, not a decimal approximation. In 1735 Euler found the closed-form solution. If you continue to Tattoo Number 4 part 2 you will see the sum.

Talking about the strangest places Pi appears, I wasn’t thinking of Pi being on PeppermintStripe’s lips. I bet she can recite 100 digits of Pi, easy! This is really cool.

Tuesday Physics Tattoo : Jono’s Maxwell’s Equations


Love the bright red question mark for the Gauss’s law. It leave open the possibility of a magnetic monopole.

Especially since most physicists believe that the magnetic monopoles do exist.

If the magnetic monopoles do exist then the Gauss’s law (third equation) needs to be changed and I think Faraday’s law (second equation) will change too.
