Rosa and Dot
Today is October 13th. It is Ada Lovelace Day:
Ada Lovelace Day is an international celebration of the achievements of women in science, technology, engineering and maths (STEM).
Today is also a Tuesday. That means that Codebar is happening this evening in Brighton:
Codebar is a non-profit initiative that facilitates the growth of a diverse tech community by running regular programming workshops.
Rosa and Dot are Ruby programmers. They’ve poured an incredible amount of energy into making the Brighton chapter of Codebar such a successful project. They’ve built up a wonderful, welcoming event where everyone is welcome. Whenever I’ve participated as a coach, I’ve always found it be an immensely rewarding experience. For that, and for everything else they’ve accomplished, I thank them.
Brighton is lucky to have them.

Jocelyn Bell Burnell
When most people see Peter Saville’s iconic cover for Unknown Pleasures, they think of Joy Division and the tragically early death of lead singer Ian Curtis. But whenever I come across variations of FACT 10, I see a tribute to Jocelyn Bell Burnell.
The album’s artwork is an inverted version of an illustration from the Cambridge Encyclopedia of Astronomy (which brings up all sorts of fascinating questions about Saville’s “remixing” of the original). It represents a series of pulses from CP 1919, the first pulsar ever discovered.
The regularity of the radio pulses is what caused the source to be initially labelled LGM-1, standing for “Little Green Men.” But the actual cause of the speed and regularity turned out to be equally stunning: a magnetised incredibly massive neutron star rotating once every 1.3373 seconds.
Pulsars keep their regularity for millions of years. They are the lighthouses of their host galaxies. When Carl Sagan was designing the Pioneer plaque and the Voyager golden record, he included a pulsar map that pointed the way to Earth—a decision that was criticised by many for inviting potentially hostile attention.
That first pulsar— CP 1919 (or LGM-1)—was discovered by Jocelyn Bell Burnell on November 28, 1967 while she was still a PH.d student, using the radio telescope she helped build. In fact, she discovered the first four pulsars. In 1974, the Nobel Prize in physics was, for the first time, awarded to an astronomer. It went to her Professor, Antony Hewish.
Jocelyn Bell Burnell herself claims no animosity on this point, but I can’t help but wonder if the committee might have made a different decision had the discoverer of one of the most important astronomical finds of the twentieth century had been a man.
She describes how the Daily Mail ran the pulsar discovery story with the headline Girl Discovers Little Green Men:
They did not know what to do with a young female scientist, you were a young female, you were page three, you weren’t a scientist.
For a fascinating insight into the career of Dame Jocelyn Bell Burnell, I highly recommend listening to Jim al-Khalili’s interview with her on BBC 4’s The Life Scientific.
