Physicists cause the confusion

It is a disappointment that Michael Tieman does not understand the explanation of Stephen Hawking being weightless (Stephen Hawking confused?, Letters to the Editor, June 22 issue).

It is physicists that cause so much confusion about centrifugal force, which makes anything in orbit weigh less and encourages the use of the term “Zero-G.”

Stephen did not say anything to correct the mistake about Zero-G.
