Next Meeting:  August 2nd

Fellow amateur astronomer and SWFAS member John MacLean will be presenting at the August meeting of the South West Florida Astronomical Society. John’s presentation entitled “From Pythagorus to Einstein; and How Much Older (or younger) is that Twin Brother anyhow?” will discuss Special Relativity and the Twin Paradox and will demonstrate the actual derivation of the equation for time dilation. If you are in the mood for some intense mental gymnastics you will not want to miss this presentation although, if you are like me, you may leave with a slight headache.

John’s presentation will begin at 7:30pm on Thursday, August 2nd, at the Calusa Nature Center and Planetarium. As usual, the regular monthly meeting of the SWFAS will follow immediately thereafter.

We meet the 1st Thursday of the month (7:30 P.M.): Calusa Nature Center and Planetarium, 3450 Ortiz Avenue, Fort Myers, FL 33905-7811.
