The Universal Timekeepers: Reconstructing History Atom by Atom

Join the Amateur Astronomers Association of Princeton in person at Peyton Hall or on Zoom on Tuesday, February 13, 2024 at 7:30pm for the AAAP’s monthly meeting and presentation. Astronomer and Columbia University professor, Dr. John David Helfand will discuss his recent book “The Universal Timekeepers: Reconstructing History Atom by Atom.” Using the basic building blocks of matter as imperturbable little clocks, Dr. Helfand will discuss how we are now able to reconstruct a remarkable range of events. From detecting art forgeries to dating archeological sites and even revealing the events surrounding the origin of life and the Universe itself, atoms provide a precise chronology from the beginning of time to the moment humans emerged to contemplate such questions. Copies of Dr. Helfand’s book will be available for purchase, and he will be pleased to sign them. For more information visit the AAAP’s website
