If you find that your money is already designed to celebrate science, you are probably in the UK.
We've had loads of scientists and engineers on banknotes, including Charles Darwin, Issac Newton, Matthew Boulton, James Watt, Michael Faraday, Alexander Graham Bell, Adam Smith, George Stephenson, Florence Nightingale and Christopher Wren.
Also the coins regularly have geeky stuff on them. Like the current £2 coin which features gears and circuitry with Newtons 'shoulders of giants' comment written around the edge. - https://www.thelondoncoincompany.com/coinimages/1329309475-2...

edit - This Northern Irish £5 featuring the space shuttle is awesome and is probably the coolest Stirling note ever.
It is also in portrait like the designs suggested in the article and could well be the inspiration for them.
