It was the German philosopher Carl G. Hempel, in a visit to Harvard in 1953–4 (replacing W.V. Quine who was on leave), that motivated him to pursue Philosophy of Science. Upon getting a Harvard Traveling Fellowship, Achinstein spent a year in Oxford in 1959 working under the guidance of P. F. Strawson. In Oxford he attended seminars and lectures delivered by Gilbert Ryle, A.J. Ayer, and J.L. Austin.

Among them are Particles and Waves, which received the prestigious Lakatos Award in 1993. This book is a study of methodological problems arising from three episodes in 19th century physics: the wave-particle debate about light, the development of the kinetic-molecular theory, and the discovery of the electron.
