ЩΉӨ BЦIᄂƬ ƬΉΣ PYЯΛMIDƧ | PBS Science Video

Who built the pyramids? The colossal geometric monuments found at Giza and elsewhere in Egypt are some of Earth’s most impressive constructions. Pyramids are truly wonders of the ancient and modern world.

But when the pyramids were built, the ancient Egyptians hadn’t invented the wheel, developed bronze tools, or discovered pi. How were they able to stack two million stone blocks, each weighing more than two tons, into precise geometric alignments that would survive more than 4,000 years and capture the imaginations of explorers throughout history? They did it the same way we always have: by trial and error. The true history of the pyramids is one of experimentation and science, not magic… or aliens.

This is an installment of the PBS – It’s OK to be Smart series. If no film or link appears in this email, go to the blog to view it by clicking on the blog title above. If the film stops & starts in an annoying manner, press pause (lower left double bars ||) to let it buffer and get ahead of you.  [Chuck Almdale]

    Chuck aka Chukar,

    Thanks for sending these out, always interesting.

    Please let me draw your attention to this Deep Look on grunion: https://ww2.kqed.org/science/2017/06/06/these-fish-are-all-about-sex-on-the-beach-deep-look/

    Since it’s “the season” and also since your group kindly hosted me for a presentation last year, it may be of interest to your group. This was partially filmed in our lab at Pepperdine and on the beach here in Santa Monica Bay.

    All best, Karen

      Hi Karen: Glad you like the videos.
      I’ve scheduled the grunion film for July 3, following your timely suggestion.
      I’ve been running the Deep Look series in date sequence and it was scheduled for 9/29, but I moved it up.

      Sometime in October or November I’ll be all caught up on the Deep Look series. If you have any suggestions for a good series to replace it, let me know.
      Chuck
