Dr. Alexandra Reed
With over a decade of experience teaching undergraduate physics, Dr. Alexandra Reed founded PhysicsFundamentalsGuide.com to make rigorous, accurate physics education freely accessible to learners around the world — from high school students to curious adults.
A Physicist Who Teaches Clearly
Dr. Alexandra Reed holds a PhD in Applied Physics and has spent over ten years teaching introductory and advanced physics at the undergraduate level. During those years, she observed one recurring problem: most freely available physics content online was either too shallow to be useful, too technical to be readable, or simply inaccurate.
PhysicsFundamentalsGuide.com was built to fill that gap — a free resource that takes physics seriously without losing the reader. Every article is written with the same standard Dr. Reed applied to her own lectures: accuracy first, clarity second, and never sacrificing one for the other.
Her approach is built on the belief that the best way to understand a complex concept is through real-world examples, clear analogies, and honest explanation — not jargon or over-simplification.

Science Writer
Author of hundreds of physics articles, guides, and educational content pieces on core physics topics.
Physics Specialisations
Classical Mechanics & Kinematics
Newton’s Laws, motion equations, energy conservation, momentum, rotational dynamics, and projectile motion — the core of introductory physics taught with precision.
Quantum Mechanics & Modern Physics
Wave-particle duality, the uncertainty principle, atomic structure, quantum tunnelling, and the quantum model of matter — explained without unnecessary abstraction.
Special & General Relativity
Time dilation, length contraction, mass-energy equivalence (E=mc²), spacetime curvature, and the implications of Einstein’s theories for our understanding of reality.
Thermodynamics & Waves
The four laws of thermodynamics, heat transfer, entropy, wave motion, sound, interference, and their applications in everyday technology.
Electromagnetism & Optics
Electric and magnetic fields, Maxwell’s equations, electromagnetic radiation, light, lenses, and the physics behind modern electronics.
How Content is Written & Verified
Every article published on PhysicsFundamentalsGuide.com is researched, written, and reviewed by Dr. Reed using the following standards:
Scientific Accuracy
All physics facts are verified against established textbooks, peer-reviewed sources, and scientific consensus.
Clear Language
Concepts are explained in plain English first, with mathematical formulas introduced after the concept is understood.
Real-World Examples
Every major concept is illustrated with a real-world application — from GPS satellites to microwave ovens.
No Exaggeration
We never exaggerate physics to make it sound more dramatic. Accurate representation always comes first.
