cosmic rays were discovered in about 1911. Most are high energy protons coming from space, and some of them have energies that are like trillions of times higher than the large hydro and collider beam energies. And it has been a real challenge to understand exactly the mechanisms of how those very high-energy protons are formed out in space. But personally, I would really like to understand exactly how that process works in case we can learn something about that - or how we could confuse them.
Physics has always sought to deepen our understanding of the nature of matter and the world around us. But how do you conduct experiments with the fundamental building blocks of existence? How do you manipulate a particle a trillion times smaller than a grain of sand? How do you cause a proton to sail around a twenty-seven-kilometer-long loop 11,000 times per second? And, crucially, why is all this important? In The Matter of Everything, accelerator physicist Suzie Sheehy introduces us to the people who, through a combination of genius, persistence and luck, staged the experiments that changed the course of history.
Shermer and Sheehy discuss: what it’s like being a female physicist in a mostly male field • Does science progress through falsification, confirmation, consensus, or Bayesian reasoning? • atoms, light, Higgs Boson, time, gravity, dark energy, dark matter, string theory, radioactivity • Gold Foil Experiment • cloud chambers • particle accelerators • splitting the atom • Is there a place for God in scientific epistemology? • Is math all there is? Is math universal? • other universes, dimensions, and the multiverse.
Suzie Sheehy is a physicist, science communicator and academic who divides her time between research groups at the University of Oxford and University of Melbourne. She is currently focused on developing new particle accelerators for applications in medicine. The Matter of Everything is her first book.
