In 2018, a scientist was handed a $3 million Breakthrough Prize for a discovery she made decades earlier, a very public apology for one of the most intimate snubs in the history of science. She kept none of it, giving every cent away to fund students from underrepresented backgrounds. This is the story of Dame Jocelyn Bell Burnell, who discovered pulsars in a freezing field with 96 feet of crinkled chart paper and was left off the Nobel Prize that followed.

It follows her from a Northern Irish childhood where her parents fought the school just to let her read a science book instead of darning socks, through a failed 11-plus exam that serendipitously rerouted her to a Quaker school that rewired how she thought, to the muddy Cambridge field where she swung sledgehammers to build a radio telescope. At its heart is "the scruff," the tiny anomaly everyone else would have filtered out, and the courage to interrogate it instead.

• Growing up at "Solitude" with planetarium blueprints on the kitchen table
• Failing the 11-plus: the exam that sorted 11-year-olds, and the lucky detour it caused
• Principles over memorization: the Quaker physics teacher who taught her to derive, not recite
• The scruff in the data: spotting a perfect pulse and fighting her own advisor to prove it was real
• The Nobel snub, the $3 million she gave away, and why a modern algorithm would have deleted her discovery
