Neutrino physics is becoming more popular and attractive since it is, relatively speaking, cheaper than big accelerator physics compared to the cost of, for example, the Large Hadron Collider.
The curiosity about the world around us is a big part of what makes us human. It’s the drive to seek answers to how nature works and understanding our own place within it that’s allowed us to have a good quality of life over a period of time.
The predecessors of today’s neutrinos might have played a role in causing matter to dominate over anti-matter in the early universe.
Soon after the Big Bang we expect there should have been roughly equal amounts of matter and anti-matter. But if that were the case those two kinds of particles would come together and destroy each other and you might be left with just a sea of radiation. We know that’s not the case because we’re here. So the universe today is dominated by matter. How did that come about?
Ray Jayawardhana: Being a scientist has given me a chance to see the world.
Growing up as a kid I was interested in science but I was also interested in many other things. When I came to university in the U.S. I was quite drawn to the idea of a liberal arts education where you get exposed to a number of different disciplines and you get some sense of how different disciplines approach their practice.
