Cooksey was the son of George Cooksey from Birmingham, England and Linda Dows from New York. After High School at the Thacher School in California, Donald Cooksey followed his brother Charlton Cooksey (a physics professor at Yale) and attended Yale and where he too became a physicist specializing in designing and building scientific instruments, especially detectors for measuring sub-atomic particles such as neutron
The neutron is a subatomic particle, symbol or , which has a neutral (not positive or negative) charge, and a mass slightly greater than that of a proton. Protons and neutrons constitute the nuclei of atoms. Since protons and neutrons behav ...
