Episode 40. Optics: Many properties of light are properties of waves, including reflection, refraction, and diffraction.
“The Mechanical Universe,” is a critically-acclaimed series of 52 thirty-minute videos covering the basic topics of an introductory university physics course.
Each program in the series opens and closes with Caltech Professor David Goodstein providing philosophical, historical and often humorous insight into the subject at hand while lecturing to his freshman physics class. The series contains hundreds of computer animation segments, created by Dr. James F. Blinn, as the primary tool of instruction. Dynamic location footage and historical re-creations are also used to stress the fact that science is a human endeavor.
The series was originally produced as a broadcast telecourse in 1985 by Caltech and Intelecom, Inc. with program funding from the Annenberg/CPB Project.
The online version of the series is sponsored by the Information Science and Technology initiative at Caltech. ist.caltech.edu

I Absolutely Love This Series. Remember Seeing Them In The '80s, Then Decades Later Wishing I Could Find It Again.

Oh, thank you so much! I have pondered since as a junior how mirrors work. All I needed was this lecture. Sometimes the answers come after nearly 40 years..

They should put the entire series on iTunes, for people who enjoyed this show on iPods or iPhones.

Some tricky thinking-visualisation required to analyse the true e-Pi-i reflection at Absolute Zero-infinity reference-framing in superimposed frequency-amplitudes density-intensity relative-timing of Bose-Einsteinian coherence-cohesion objectives in condensation-superposition.., the Reflection reference-framing is how instantaneous Sublimation-Tunnelling distribution holography dimensionality operates, ie constant creation metastable proportioning probabilities of collapsed wave or Singularity-point cause-effect positioning. Aether is holographic cause-effect.. The phenomenon of Reflection and log-antilog numberness condensation modulation cause-effect mechanism everywhere-when all-ways all-at-once is one of those pure-math reverse reasoning ideas that match the no cloning aspect of ONE-INFINITY Singularity QM-TIME Completeness, the future-omnipresence-past superposition here-now-forever => minimum time duration timing path, together in sync-duration.., and the Electron Cloud phonon crystallisation required for Superconduction is determined by the relative-timing reciprocation-recirculation of 2-ness tangency-> orthogonal-normal Quantum-field evaporation to cubic line-of-sight parallels instantaneously. IMO, that Exclusion Principle Imagery proposition that has two Electron orbital in opposition, is the sane inside-outside holographic positioning presence of Electron Positron pairing of orthogonal-normal vertices in vortices, projected via Singularity-point Lensing. (Work for Physicists and Geometers to demonstrate graphically, Lyman-Balmer reverse process)

i would pay to get this whole series in high quality.
@sovietmaths5651
@sovietmaths5651 2 года назад
Unless we upscale it, I don't think we can get it in high quality. Even if we had the original film, the graphical models (of the reflective telescope for example) would have been created originally at a lower resolution. Unless you wanted to recreate it from scratch, it can't be done. And.. if you had the budget to redo all of the graphics, etc, why would you just not create a new series. For mastering the audio- it probably would be cheaper.

The (hi-def) DVDs are available from, I believe, The Annenberg CPB. I borrowed them from my local library, so I know they exist.

Please fix the audio / video sync. The audio is ahead by about 15 seconds - probably the video credit at the beginning for Annenberg Media.

How can waves destruct each other?What happened to the law of conservation of energy?
@JivanPal
@JivanPal 2 года назад
Consider water: the water particles that are moving in order to create a wave (call it wave A), have kinetic energy. When a wave of opposite amplitude (whose particles also have kinetic energy; call it wave B) coincides with A, the kinetic energy that the particles of B have is used to do _negative work_ (from the perspective of A) on the particles of A. Energy is conserved, but it is in some sense directional. Your question is no more demonstrative of the conservation of energy (or supposed lack thereof) than asking why two cars coasting directly towards each other at the same speed collide to a stop: each does negative work on the other. Perhaps it is clearer to see in these examples that _momentum_ is conserved.
