hello
Welcome to the web site of Dr. Mark P. Silverman, Jarvis Professor of Physics
at Trinity College. I am a physicist whose scientific interests and
contributions fall broadly in the areas of quantum physics, atomic &
nuclear physics, optics & electromagnetism, and gravitation. I am also
a teacher who has developed humane and effective educational methods for
teaching science at all levels of instruction. At this site you can find
books and papers in which I discuss my scientific research and
educational experiments. More about me »
New Books
2nd Edition (April 2015) Cambridge University Press  ISBN13: 9780521446310
This book of essays, recently released as a second edition, is a largely nonmathematical account of some of the strange behaviour, both classical and quantum, exhibited by diverse physical systems. Drawn from the author's wideranging researches in quantum mechanics, atomic and nuclear physics, electromagnetism and optics, gravity, thermodynamics, and the physics of fluids, the essays describe different physical systems whose behaviour provokes surprise and challenges the imagination.

Cambridge University Press 2014  ISBN13: 9781107032811
This book examines randomness, chance, and uncertainty in matters pertaining to fundamental questions of physics as well as to issues that are likely to affect readers in personal ways. Among the topics discussed are controversial issues concerning the decay of radioactive nuclei, predictability of the stock market, safety of commercial aircraft, accelerating rise in Earth’s temperature, interpretation of medical tests, detection of drug use to enhance athletic performance, and more. The book helps develop proficiency in the use of probability and statistics to understand a multiplicity of physical processes. Read more »
Recent Work
The HalfLife of Radioactive Nuclei
Estimating the halflife of an unstable nucleus from just two measurements does not give an accurate result. However, a histogram of a large number of twopoint estimates leads to a nearly perfect Cauchy distribution centred at the true value.

The Earth’s surface temperature is increasing. However, measurements of subterranean temperature variations, which are largely insensitive to the vicissitudes of weather, indicate that the rate of temperature rise in cities can far outpace the rate of global or regional warming.

Recurrent Patterns in Random Events
The common perception (see Wikipedia) of randomness is that it is devoid of all order, pattern, or predictability. However, that is a misperception. It is precisely the existence of patterns of recurrence that characterise a random process and serve usefully in many ways, among which is to test the randomness of quantum events.
