Sabine Hossenfelder

"Theoretical physicists used to explain what was observed. Now they try to explain why they can't explain what was not observed."

Fearlessly critical of the scientific mainstream, Sabine Hossenfelder is a groundbreaking theoretical physicist who specialises in the foundations of science. She is a leading science communicator, a best-selling author, and a researcher. Her recent books include Lost in Math: How Beauty Leads Physics Astray, and the New York Times' Best Selling Existential Physics: A Scientist's Guide to Life's Biggest Questions.

Hossenfelder also has a popular YouTube channel,  "Science without the gobbledygook," that has amassed over 80 million views. Her writing has featured in some of the world's top publications, including Scientific American, New Scientist, and Nautilus.

“A physicist who is utterly fearless, completely honest, and quite funny.” - Peter Woit, mathematical physicist
