Theoretical Physicist & Science Communicator

Dr. Marcus Webb

PhD in Astrophysics — California Institute of Technology (Caltech)

Dr. Marcus Webb earned his PhD in Astrophysics from the California Institute of Technology (Caltech), where his doctoral research focused on gravitational wave detection and the dynamics of compact stellar objects — neutron stars, pulsars, and stellar-mass black holes. His work contributed to theoretical models used in the analysis of data from ground-based interferometric detectors.

After a decade conducting and publishing research, Dr. Webb transitioned to science communication — motivated by the conviction that the most revolutionary ideas in physics, from the geometry of curved spacetime to the strangeness of quantum measurement, are understandable to anyone willing to engage seriously with the concepts. He has since written extensively on classical mechanics, modern physics, and gravitational theory.

Dr. Webb's articles are characterised by rigorous derivations paired with real-world examples — he believes that physical intuition and mathematical precision reinforce, rather than compete with, each other. His writing on special relativity, radioactive decay, angular momentum, and circular motion aims to give readers the same conceptual toolkit he developed over years of research.
