Val Fitch – Banquet speech

Val Fitch’s speech at the Nobel Banquet, December 10, 1980

Your Majesty, Your Royal Highnesses, Ladies and Gentlemen,

Earlier today Professor Ekspong described our research which showed a basic lack of symmetry between matter and antimatter, world and antiworld. He observed that, if from some remote stellar region an alien space craft comes to visit, we now have a few experiments to suggest before shaking hands and possibly reducing ourselves to nothing more than gamma rays.

Such a hypothetical catastrophe only emphasizes the fact that everything on this planet is made of the same substance – it emphasizes the essential unity of every living thing.

Through your efforts these awards have come to signify the best of human endeavor and they promote, probably to a greater extent than any other tradition, the unity of mankind.

Professor Cronin and I express our deepest gratitude for this high honor on this splendid occasion. Thank you very much.

Interview, March 2009

Interview with the 1980 Nobel Laureate in Physics, Val Fitch, 17 March 2009. The interviewer is Adam Smith, Editor-in-Chief of Nobelprize.org.

Val Fitch begins by sharing his experiences as a child growing up in Gordon, Nebraska, his work as a young army technician on the Manhattan Project (8:51), witnessing the Trinity Test (18:05), and his work as a graduate student for Nobel Laureate James Rainwater (24:50). He then discusses his discovery of CP-violation (32:17), future areas of scientific exploration (38:28), table-top experiments in physics (44:40), and concludes by returning to his memories of the many great scientific minds assembled at Los Alamos (50:21).
