Physics is the study of extremes – the fastest, the smallest, the most energetic, the coldest and the hottest. Because physics researchers are pushing the limits of what can be measured, they often must build their own instruments from scratch to do the measuring. What physicists actually study—the fundamental particles and forces that form and govern our universe—may not be as familiar to you as the concerns of other fields, like medical research. However, the ideas behind these experiments and the tools built to accomplish them have had real, lasting impacts on daily life.
