Physicists have come out on top in Princeton University’s fourth “art of science” competition.
The annual exhibition features images created during scientific research and this year’s event was held on 7 May with the theme of “energy”. Jerry Ross, a postdoc at the Princeton Plasma Physics Laboratory won first place for his “xenon plasma accelerator” image. The picture (below) is of a so-called “Hall effect thruster” – a type of ion thruster where electrons, held in a magnetic field, are used to ionize a propellant, which is then used to produce a thrust.
Third place also went to a physicist. Tim Koby, a physics undergraduate at Princeton, produced a picture of the interaction of a neutron star with a black hole in the centre of a galaxy.
Koby was beaten into second place by David Nagib, a chemistry graduate at Princeton who produced an image called “therapeutic illumination”.
Ross bagged $250 for winning best exhibit, with $154.51 awarded to Nagib in second place and $95.49 to Koby in third.
And if you are wondering why those last two figures are not rounded to $150 or $100, it is apparently because they are derived according to the golden ratio – equal to 1.6180339887 – that represents, in this case, the ratio of the higher to the lower number.
