A physics newsletter that explains the intuition behind concepts such as why temperature feels different to touch and why nothing can reach light speed, using concrete experiments and everyday examples. Each issue is a single deep-dive aimed at curious readers who want to understand the ideas rather than memorise formulas.

A weekly essay series that takes one idea from physics, biology or neuroscience (such as information, entropy or phase) and follows it toward living systems and minds, aiming for about ten minutes of reading. Each issue is an accessible, evidence-bounded explanation with a clear authorial voice.
Technical explainers and analysis from an experimental physicist on quantum computing hardware, error correction and industry structure. Readers get context on recent papers and engineering trade-offs, backed by concrete numbers.
A neuroscientist's bar-themed essay newsletter that explains science through long, character-driven pours, such as how the brain clears waste during sleep and how Brownian motion and termite stigmergy work. Readers get clear, well-sourced explanations of physics and biology wrapped in a personal, storytelling voice.
Astrophysicist Ethan Siegel explains cosmology, astrophysics and space missions in long-form essays and an 'Ask Ethan' reader Q&A series. Each issue unpacks questions like dark matter's nature, Martian moon origins, and the Hubble constant in accessible but technically grounded prose.
