As we understand it at the moment, the matter and all the stuff that we've discovered only covers about four or five percent of the mass energy content of the universe as we know it. And yet how incredible it is that over the space of just like 100 years, we've managed to build technologies that are able to measure these things. The Higgs boson was one that I thought might not be discovered in my career. But even I didn't expect to see all of this happening within my career. It's important for even me as a trained physicist to be able to say, I doubted that and I was wrong.
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.
