Best Fundamental physics Videos
「Fundamental physics」下面有164部被不同的人、在不同月份推荐过的视频。挑的时候先看对象:入门12部,适合还没学过的人;进阶23部,适合已经懂术语的人;普通向122部,按兴趣就能看;更硬的7部,留给想看推导或细节的人。这一类数量最多的是讲解,所以它们的共同点是用一个图像或类比把一个概念补上。常出现的频道包括Veritasium、PBS Space Time、Christopher Sykes。目录给这个主题划的范围是:Physics: classical mechanics, relativity, thermodynamics, electromagnetism, Feynman lectures, physical law, physics courses, Walter Lewin, Veritasium, physics explainers and demonstrations.如果只看三部,就从《I bought 1000 meters of wire to settle a physics debate》开始,它负责把问题讲出画面;然后看《The Speed of Light is NOT About Light》,换一种讲法或例子;最后看《Why No One Has Measured The Speed Of Light》,留给已经有基础的人。页面按每页24部切开,顺序看的是被推荐跨越了多少个月,不是播放量。每条标题下面那一句是这部片子自己的内容说明,用来区分它在讲定义、过程、演示还是观点。点进去能看到推荐原话、原文链接和适合谁看。看的时候把强烈推荐当成有人明确叫你去看,把引用当成只是拿来举例,把批评留下来对照,不要把每条评论都当成同一力度。

Lecture 1 | Modern Physics: Classical Mechanics (Stanford)
The first lecture of Leonard Susskind's Stanford Continuing Studies course on modern physics, beginning with classical mechanics.

Turning Waves Into Particles
Huygens Optics explores the idea that space is a non-linear elastic medium, and uses simulations to show how wave energy might be confined locally into particle-like objects.

Reynolds Number - Numberphile
Numberphile with Tom Crawford of Oxford explains the Reynolds number, the second of three videos on Navier-Stokes and fluid flow, with demonstrations of laminar versus turbulent behavior.

The Maths of General Relativity (1/8) - Spacetime and Worldlines
The first of an eight-part ScienceClic series building general relativity, covering worldlines, proper time and coordinate systems with animated visualizations.

A Physics Professor Bet Me $10,000 I'm Wrong
Veritasium recounts a $10,000 bet with a UCLA physics professor over whether a vehicle can travel downwind faster than the wind.

The Absurdity of Detecting Gravitational Waves
Veritasium explains in detail how LIGO detects gravitational waves, with a laser interferometer measuring displacements smaller than a proton.

Why is Time a One-Way Street?
Leonard Susskind's Santa Fe Institute talk on the arrow of time: why the past differs from the future when physics equations are time-symmetric.

The Strangest Implication of Quantum Mechanics
A Veritasium video that follows the principle of least action from Bernoulli and Newton to quantum mechanics, asking whether light takes all possible paths at once.

Feynman: Magnets FUN TO IMAGINE 4 But see NEW UPDATED file at https://tinyurl.com/ycphc432
A clip from the BBC Fun to Imagine series in which Richard Feynman is asked how magnets work and explains why 'why' questions depend on a shared framework of understanding and cannot always be answered in layman's terms.

David Deutsch on Physics Without Probability
A 2015 talk by David Deutsch with slides and audio about constructor theory and how physics, in particular the many-worlds interpretation, can be framed without probability.
