Why Pink Doesn’t Exist: An Illustrated Stop-Motion Science Explanation in 60 Seconds

By:

Pretty in minus-green.

If OK Go’s stop-motion color theory for Sesame Street met mathemagician Vi Hart’s hand-drawn math lessons, you’d get Minute Physics — charming and illuminating hand-illustrated science animations, like this fantastic explanation of how the color pink exists even though pink light doesn’t.

Speaking in terms of light, pink should probably be called ‘minus-green,’ because pink is just the leftovers of white light when you take out the green.”

For more on the curiosities and quirks of the science of perception, don’t forget Mark Changizi’s fascinating The Vision Revolution, which explores why we see the way we do.

The Art of Medicine: Mapping the Body in 2,000 Years of Images and Imagination

By:

From ancient etchings to electron microscopes, or what aspirin has to do with visualizing consciousness.

Since time immemorial, humanity has been turning its gaze outward, ordering the heavens, and inward, mapping the mind, in an effort to better understand who we are and where we belong. The human body itself has always been a fascinating frontier of inquiry as we’ve bridged art and science to visualize the living fabric of our shared existence. The Art of Medicine: Over 2,000 Years of Images and Imagination offers a remarkable and unprecedented visual journey into our collective corporal curiosity with a breathtaking selection of rare paintings, drawings, prints, sculptures, artifacts, manuscripts, manuals and digital art culled from London’s formidable Wellcome Collection. Contextualized by medical historian Julie Anderson and science writers Emm Barnes and Emma Shackleton, these magnificent ephemera span cultures and eras as diverse as Ancient Persia and Renaissance Europe to paint a powerful, visceral portrait of our civilization’s evolving ideas about health, illness, and the body.

Artist Anthony Gormley writes in the foreword:

The body is the root of all our experience, through it all our impressions of the world come and from it all we have to share with the world is expressed. A collection such as Wellcome’s is an extraordinary resource for thinking about the body, both as a thing, a metaphor, and the place where we all live and on which our consciousness depends.

We live in and with the body, yet as many of the images here show, we need to constantly re-imagine it. Wellcome’s collection, open to the convergence of the forensic and the imaginative, allows for the mind of the curious to recognize the body as a time machine headed on an ultimately entropic journey.”

Equal parts fascinating and fanciful, The Art of Medicine is a magnificent almanac of the body’s timeless mystery and its visual vocabulary.

This Is Your Brain on Comedy

By:

The laugh track as cultural currency, or what David Letterman has to do with the dopamine circuit.

“At the height of laughter, the universe is flung into a kaleidoscope of new possibilities,” author and philosopher Jean Houston once said, and Walt Disney famously called laughter “America’s most important export.” But what exactly is humor, and why does it have such a profound effect on us? In this talk from TEDxRainier, comedian Chris Bliss — whose writing credits include The Tonight Show and The Late Show with David Letterman — explores the sociology and neuroscience of humor, the alchemy of laughter, and why honesty and integrity are at the heart of good comedy, using a handful of Pretty Damn Good jokes to illustrate these insights along the way.

I want to talk [about] the unique power the best comedy and satire has in circumventing our engrained perspectives — comedy as the philosopher’s stone that takes the base metal of our conventional wisdom and transforms it, through ridicule, into a different way of seeing, and ultimately being, in the world… It is about communication that doesn’t just produce greater understanding within the individual, but leads to real change… communication that manages to speak to and expand our concept of self-interest.”

For more on the psychology and philosophy of comedy, see John Morreall’s Comic Relief: A Comprehensive Philosophy of Humor and Robert Provine’s Laughter: A Scientific Investigation.

Thanks, Phil
