This introduction to the series Albert Michelson’s Harmonic Analyzer celebrates a nineteenth century mechanical computer that performed Fourier analysis by using gears, springs and levers to calculate with sines and cosines—an astonishing feat in an age before electronic computers.

    HE IS SITTING ON ONE SPOT but it feels like he is everywhere right nowyou are awesome

  2. Mike Hughes says

    thank you!

  3. Nikolaos Vitoroulis says

    This 4 video series has warmed my soul.

  4. sevenhornets says

    I had a vocabulary aneurysm in this video.

  5. Test page 1 says

    In today's announcement of the black hole image, the scientist remarked that the image processing eventually relied on an anonymous 200-year-old equation. Guess which one.

  6. ReBootYourMind says

    I would like to see a video about the function of the Curta Calculator from you.

  7. C Miller says

    Has anyone a demo of the henrici analyzer?

  8. mp lites says

    Pls do how granade works..

  9. PoorGamer says

    Can it run crysis?

  10. Rudraksha Shah says

    Course the inventor was an Albert. No disrespect to the guy I love him just making a joke.

  11. Rick Wood says

    This thing doesn't even have Minesweeper.

  12. ANO NYM says

    what's the difference between sin and cosin again? sorry for being stupid

  13. Choice777 says

    but can it run Crysis ?

  14. Jim Hawkins says

    My first computer program of any significance was one that added up the sin wave harmonics with coefficients to plot out the resulting square wave in asterisks on a TI thermal printing terminal. That was in 1975. I learned Fourier analysis in 1968 in college and have been fascinated with it ever since.My ham radio transceiver is an SDR that does repeated FFTs to show me the spectrum of the band. I have yet to grasp how FFTs work. It's always fascinating to see this topic presented in as many ways as possible to continue to strengthen my understanding. Thanks for these lessons!

  16. Kandi Klover says

    Thank you so much for this. I've always loved mechanical and early transistor computers. Huge contribution to the computer history here from you and monumental to see this machine come alive after so long.

    $225 in 1913, adjusted for inflation where 1913 is the earliest we have data for, would translate to $5,690 in 2018

  18. Eric Moses says

    But seriously, who is down voting this guy? What could you possibly find in engineering videos to down vote? Maybe hypocritical luddites reluctantly using the internet?

  19. Rick D Ellis says

    When did Mark Hamill get so smart?

  20. Drew Ford says

    Your video may have been stolen. https://youtu.be/GyYflzRVu6M

  21. ZVG says

    Ah dawg, you make some dope vids, solid shit. Stay grinding.

  22. Thomas Alexander says

    This channel is really educative,,Never see other channel done this before

  23. Jeff Brubaker says

    would make a cool kit to order

  24. J M says

    AWESOME!!!

  25. Andrew Borne says

    Well done series! Very clear instruction. You have a great voice too.

  26. Skiddla says

    i want to build things
