According to your textbook, if you quoted nobel prize-winning physicist steven chu about his experiences growing up in missouri as a chinese american, what kind of testimony would you be using?

Steven chu awarded Nobel prize for his experiments on cooling and trapping of atoms with laser light in 1997.

Explanation:

Steven chu and his colleagues worked on cooling and trapping of atoms with laser light at Stanford university.

When he was in lab at Stanford University with his colleagues his eyes went on to a window of a vacuum chamber to a floating droplet of atoms that are trapped and lowered the temperature of atoms by the forces of laser light. This attention by chu lead to invent cooling the atoms with laser light.
