Sally Shrapnel shares a somewhat meandering journey into quantum science, and gives a fascinating perspective on our keyword "quantum".Sally is one of the Deputy Directors of EQUS and does theoretical research into pretty deep ideas like "causation" and "the arrow of time", but this doesn't mean she's detached from reality. She worked as a medical doctor and rural GP before becoming a quantum scientist, and has some great stories (and advice) from her less direct career journey. Her combination of expertise enabled Sally to help work out important things about COVID-19 early in the pandemic, and she reminds us that physicists have a tremendous range of skills to offer the world in all sorts of data-driven situations. Also, we ponder the limits to what can be learnt and hear what quantum sounds like to a theoretician!The world is a better place when more people know about quantum science.
