I recall my interactions with Julian Schwinger, first as a graduate student at Harvard, and then as a postdoc at UCLA, in the period 1968--81, and subsequently. Some aspects of his legacy to physics are discussed.

In the period 1968 - 1974 I was a graduate student and then a postdoc at Caltech and was involved with the developments of the quark and parton models. Most of this time I worked in close contact with Richard Feynman and thus was present…

In these shorts notes I want to remembermy relationship with GianCarlo Ghirardi, who was my supervisor in my Master Degree in Physics at the University of Trieste and then he became a very deep and close friend. I don't want to describe in…

I give an account of what it was like to be a PhD student of Abdus Salam and also to take part during the early stages of the development of supersymmetry.

I shall use a few personal reminiscences of my time as a student and colleague of Dirac in Cambridge to introduce some reflections on the nature of research in theoretical physics. I shall discuss and illustrate the approach of Dirac to his…

I present some reminiscences, both personal and scientific, over a lifetime of admiration of, and friendship with, one of the Grandmasters of our subject.

Recollections by the author about how his interactions with John Wheeler influenced his career in physics.

The years 1998 to 2008 were very exciting years for cosmology. It was a pleasure to accept this invitation to describe my contributions to the development of our knowledge and understanding of the universe over the course of the past…

These are some thoughts contained in a letter to colleagues, about the close relation between gravity and quantum mechanics, and also about the possibility of seeing quantum gravity in a lab equipped with quantum computers. I expect this…

This article gives a sketch of teachers and colleagues who have had strong influence on my becoming a particle physicist.

While collecting some personal memories about Julius Wess, I briefly describe some aspects of my recent work on many particle quantum mechanics and second quantization on noncommutative spaces obtained by twisting, and their connection to…

Brief recollections by the author about how his work with Kip Thorne influenced his career in physics.

In this invited talk, I discuss four important contributions of E.C.G. Sudarshan, among many. They are the V-A theory of weak interaction, Sudarshan - Glauber representation, tachyons and the quantum zeno effect.

These are reminiscences of my interactions with Julian Schwinger from 1968 through 1981 and beyond.

A few remarks on integrable dynamical systems inspired by discussions with Jurgen Moser and by his work.

Life at Caltech with Murray Gell-Mann in the early 1960's is remembered. Our different paths to quarks, leading to different views of their reality, are described.
