Carl Sagan Stars in Atomic Robo

Monday, August 31st, 2009

When you return to your unobservable but empirically determined dimension of origin–tell them Carl Sagan sent you!
~ Fictional Carl Sagan in Atomic Robo, Shadow from Beyond Time #4

I had previously covered a Carl Sagan cameo in the Atomic Robo comic book, where Sagan sends Dr. Atomic Robo Tesla to Mars with the Viking Lander in a dream sequence.

Well, this month’s issue features the real Carl Sagan and he opens a scientific can of whoop-ass on an extradimensional monster.

The authors really know their Sagan, and Sagan fans will really appreciate the dialog, which references many of Sagan’s books and ideas. This comic is currently renewing my enthusiasm for the medium, as guest appearances by Tesla, H.P. Lovecraft, and Charels Fort and references to various historical science locations and events really enhance the action and adventure.

I highly recommend digging into the graphic novels of this comic’s previous sets.

  • Acoustic tweezers enable flexible on-chip manipulation and patterning of cells using standing surface acoustic waves.

    Tributes to Science in the Jefferson Library of Congress

    Sunday, August 30th, 2009

    Of all the amazing cultural attractions on the Washington DC Mall this is by far the best kept secret. If you appreciate knowledge, Enlightenment values, and science, then you MUST spend an afternoon in this room, appreciating every nook and cranny. America’s Founders were very wise individuals with a strong appreciation for education and knowledge.

    There are names of philosophers, naturalists, and scientists everywhere. Proverbs meditating on Deism and knowledge abound. There are paintings of women representing the different types of literature, from history to erotica. Evidence of America’s love of science is found all throughout the building, as with a collection of cherub sculptures depicting the many noble professions, one of which is entomology, a cherub chasing a butterfly with a net.

    There are statues and paintings representing the different nations and cultures of the world, and what each contributes to world culture. Germany is credited with the “Art of Painting,” France is “Empancipation,” England is “Literature,” Spain is “Discovery,” Egypt is “Written Records,” Judea is “Religion,” Greece is “Philosophy,” Islam is “Physics,” the Middle Ages is “Modern Languages,” Italy is the “Fine Arts”…

    And America:

    The figure, an engineer whose face was modeled from Abraham Lincoln’s, sits in his machine shop pondering a problem of mechanics. In front of him is an electric dynamo, representing the American contribution to the advancement of electricity. Blashfield has signed his work on the base of the dynamo, with the accompanying inscription: “These decorations were designed and executed by EDWIN HOWLAND BLASHFIELD, assisted by ARTHUR REGINALD WILLETT, A.D. MDCCCLXXXXVI.”

    There are also eight symbolic statues in the reading room, representing philosophy, art, history, commerce, religion, law, poetry, and science. Accompanying these are sixteen bronze statues of individuals representing accomplishments in these categories of knowledge, with Newton and Henry representing science.

    The Jefferson Reading room is off-limits to visitors and photography from the observation deck is prohibited. Even if it wasn’t, the science-related statues cannot be seen from the observation deck. I looked through all the books in the LOC gift shop and could not find photos of these statues either. So if anyone can find photographs of these statues, I and America would be eternally grateful.


    My favorite of all these are the mosaics of women representing the arts of the sciences. Each woman is depicted mastering some element of nature through science, be it fire, venom, or the heavens.

    It took me four trips to this room to get photos of these murals, which I have not been able to find anywhere else on the Internet. I’m licensing these Creative Commons, so please reuse and redistribute!

    I’ve taken my photos of these faded murals and have adjusted the brightness, contrast, and color levels to enhance their beauty. The results I’ve posted below.

    Jefferson Room, Archaeology
    Archaeology

    Archaeology is depicted reading a large book with a magnifying glass. She stands on an artificial structure, with a pottery at her feet. Her clothes are more extravagant than the other women, and she wears a much jewelry and accessories.

    Jefferson Room, Astronomy
    Astronomy

    Astronomy stands at the apex of a hill or mountain, the crescent moon at her feet. She carries Saturn in her left hand, a celestial object, and what may be a lens in her right. It’s as if the lens makes the immense heavenly body her plaything.

    Jefferson Room, Botany
    Botany

    Botany is clad in green robes, standing on lily pads. In her hands she cradles a lotus bloom. The joy in her face is apparent as she appreciates the intricacies of the bloom’s unfolding petals.

    Jefferson Room, Chemistry
    Chemistry

    Chemistry toils over a pedestal with a cobra coiled around it. She is using a retort to distill liquid. Is she manufacturing an antidote from the snake’s venom?

    Jefferson Room, Geology
    Geology

    Geology stands on rocky soil, apparent from the mountains in the distance behind her. In her left hand she carries a glass orb and in her right a seashell fossil.

    Jefferson Room, Mathematics
    Mathematics

    I love the fact that Mathematics is pretty much naked, fitting for her stature as the “pure” science. Her right foot rests upon a block with “MMX” inscribed upon it. I am unable to identify what it is she carries in her hands. Is it a scroll? A geometric shape?

    Jefferson Room, Physics
    Physics

    There is wind or water flashing behind Physics, a demonstration of nature’s physical powers. Her right foot depresses the Earth where she stands. In her left hand, she carries a torch, and with her right hand manipulates the flame.

    Jefferson Room, Zoology
    Zoology

    Zoology is clad in animal skins, her stride cast in a dynamic pose, as if she were prowling like the Lion resting at her feet, which she caresses as her pet.

    See the complete flickr set here. Very high resolution photos included. The Library of Congress also has a write-up of most of the details you will find as you explore the Jefferson Library. There is also a beautiful book detailing almost everything in the library titled The Library of Congress: the art and architecture of the Thomas Jefferson Building, which you may preview with Google Books.

  • A dead herring will begin to glow for awhile until it starts to decay. In 1870, two scientists, Herrington and Lightbrown, sought to find a means of implementing regenerative bioluminescence to light up cities. Today, researchers are investigating glow-worm-lit tunnels, bioluminescent billboards, and bioluminescent plants for lighting.

    The Death of David Hume

    Tuesday, August 25th, 2009

    I did not mind not existing before I was born, why should I mind not existing after I die? – David Hume

    David Hume

    On this day, 233 years ago, the philosopher David Hume, author of An Enquiry Concerning Human Understanding, which rejected intelligent design in nature, died in what was a milestone for atheism. The religious population watched Hume’s last days closely, incapable of believing that an individual could die rejecting the idea of god and fully expecting him to recant in his final days. Instead of recanting, David Hume played cards up until his last moment of life (Schmidt, 2006).
