Metaphysics, Epistemology, and Ontology Workshop (M.E.O.W.)

The Metaphysics, Epistemology, and Ontology Workshop (M.E.O.W.) is back after a long break, and we’re kicking things off with a fascinating presentation by Professor James Blackmon!

Talk Title: “Isotacheia: How the Epicureans Could Have Derived Time Dilation”

Abstract:

One of the most counterintuitive predictions of special relativity is that physical systems in relative motion are observed to change state at slower rates at higher speeds. Time for these systems is said to ‘dilate’: muon decay rates are reduced, clocks slow down, and astronauts do not age as quickly. This phenomenon is robustly confirmed by measurements dating back to Rossi-Hall (1941). But why would time dilate? What does that even mean? The textbook explanation leaves many students puzzled and unsatisfied.

We will explore how the Epicurean atomists could have used a simple theorem of kinematics to derive the equations that physicists use today to determine time dilation for physical systems in relative motion, thereby offering an alternative explanation of this phenomenon. The derivation is brief and requires only basic algebra. The model is classical and intuitive, and all terms have direct physical interpretations.

 We can’t wait to revive M.E.O.W. with your participation! Feel free to share this announcement with peers who might be interested.
