A number plate I read as "tensor", and the object it named, a thing whose meaning survives a change of viewpoint. From scalars up to the Christoffel symbols, the geodesic equation and curvature, then back to what machine learning means by the word.
The Kerr metric reveals how rotating masses warp spacetime differently than non-rotating ones, fundamentally altering our understanding of stillness and inertia, exemplified by the concept of frame-dragging, which couples time and rotation in ways that challenge conventional notions of motion near these celestial bodies.
Explore how the universe's fundamental nature as vibrations influences our bodies and emotions, revealing that the frequencies we inhabit shape our perceptions and connections with others—like a cat's soothing purr, which may offer therapeutic benefits through its harmonic resonance.
A thermometer averages molecular chaos into temperature, just as a clock counts transitions, suggesting that both tools reveal not fundamental truths but useful proxies for the complex realities beneath them—prompting us to question what it truly means to measure time.
The TARDIS symbolizes a profound truth: as dimensions increase, our intuitions about containment collapse, revealing that what we assume to fit within a space may far exceed its boundaries, a reality that echoes in both high-dimensional geometry and the complexities of our interconnected world.
A reflection on how human experience—memory, agency, language, and narrative—shapes the frameworks we build, and what that means for time, causality, and the limits of physics as a “mirror” of reality.
An essay on why symmetry comforts the mind, how science and mathematics chase invariance, and why asymmetry—through breaking, chirality, primes, and time’s arrow—is the texture that makes life and meaning possible.
Newton’s three laws as axioms, F=ma as the grammar of change, and how energy and momentum conservation emerge—told with minimal calculus and hands-on experiments.
Physics turns wonder into practice: from Archimedes’ geometry and instruments to Galileo’s timing and idealisations, nature begins to speak in numbers we can test.
Before physics was an equation, it was a question. This essay traces its roots—from myth and wonder to natural philosophy—as humanity’s first attempt to read the book of nature.
