Fab story from Margaret Hamilton, RIP, showing why Science-Mums are brilliant scientists! When innovating at the cutting edge of technology, it's so important to bring together a wide range of lived experiences. Sad that only ~20% comp-scientists are female 👩‍🔬🧪 ℹ️: www.theguardian.com/technology/2...
Right:  A woman looking very cool in a 70's dress standing next to a massive pile of very thick books
Left text: Did your life as a software engineer and a mother ever collide?
Often in the evening or at weekends I would bring my young daughter, Lauren, into work with me. One day, she was with me when I was doing a simulation of a mission to the moon. She liked to imitate me – playing astronaut. She started hitting keys and all of a sudden, the simulation started. Then she pressed other keys and the simulation crashed. She had selected a program which was supposed to be run prior to launch – when she was already “on the way” to the moon. The computer had so little space, it had wiped the navigation data taking her to the moon. I thought: my God – this could inadvertently happen in a real mission. I suggested a program change to prevent a prelaunch program being selected during flight. But the higher-ups at MIT and Nasa said the astronauts were too well trained to make such a mistake. Midcourse on the very next mission – Apollo 8 – one of the astronauts on board accidentally did exactly what Lauren had done. The Lauren bug! It created much havoc and required the mission to be reconfigured. After that, they let me put the program change in, all right.

A fun fact about neutrinos is that they come in three “flavors” (types) and also in three masses and you would think that this means each flavor has its own mass and you would be absolutely wrong about that.

What is the IceCube neutrino observatory? Neutrinos are elusive particles that rarely interact, but can create flashes of light when they do. Most neutrino detectors are giant water tanks surrounded by light detectors. IceCube is kilometer-long strings of detectors embedded in the Antarctic ice.
