How am I seeing?

August 19, 2013

RTEmagicC_scoring_munsell.gif

I saw this story from the New York Times on glasses that can correct some kinds of color blindness and I thought that was interesting. 

It made me think about how different perceptions can be for different people.  I used to drive myself crazy when I was a kid wondering about that.  Were there some people for whom chocolate tasted terrible and liver tasted good, and what do dogs actually see, what about bees that can see ultraviolet?

I would have like to be able to see beyond the visual spectrum and wondered what it would look like if there were more colors.  I was sure that there were, if only I could see them.

Here are some ultraviolet flowers.

And you can test yourself here with the farnsworth-munsell color vision test.

The image above is from the Ishihara color vision test.  You can take that online, too.

If you were color blind would you buy the glasses?  I would think seriously about it.

For Sappy Car blogging this week, I offer this story run on NPR in April about cats and the poets who love them.

Reference: Word Tapestry, with thanks.

When I sit in the chair of the person he obviously loves best, Sam boxes me about the ears with both front paws and tries to eat my hair.  Just last night, in fact.

What am I watching?

August 15, 2013

A long time ago I heard someone describe a perception of human beings – or anything animate, really – based on time.  When looked at through that lens we are not individual objects, but move through time in the continuous tube/shape/form that our bodies make.

That concept is beautifully visualized in this video – found on Hovercraft Doggy.

What is tattoo Tuesday about?

August 13, 2013

Science tattoos – these are some of my favorites

star-navigation-440-tattoo(Above) Marc Morency, Quartermaster 1st class, USN, writes:
“My tattoo is the visual depiction of how to plot a line of position from a celestial body using the altitude intercept method, a method which has been time tested for more than a century. For me it serves as a reminder that while technology improves, the sea remains an unpredictable place and it is up to the older generation to teach the younger the old school ways of doing business.”

subatomic-doodling

(Above) Zach writes: “This is a half sleeve up my upper right arm based around an image taken by one of the CERN bubble chambers. It is based on this image. I first saw that image my freshman year of college. It had the sublime, simple beauty that only something made of math and science can have. It stuck with me for 8 more years before I actually decided to get it etched into me. Oddly enough, on Valentine’s Day. I guess it was my Valentine’s to physics and science. Oh, and when people ask who drew it, I always respond ‘God.’”

(Above) “For some time I have wanted to get a tattoo to depict my appreciation for meteorites. On September 28, 1969 meteorites fell in Murchison, Australia. On September 28, 2004 our daughter Christina (a.k.a. Pinky) was born. As if wasn’t already a top-fiver for it’s amino acids, Murchison quickly moved up the ranks of my favorite meteorites and I had decided it would somehow be involved in the meteorite tattoo. With a little help from friends Steve Arnold (IMB) and Jason Phillips I obtained a small capsule of Murchison crumbs to pulverize and one day add to the ink. I ultimately decided on a carbon buckeyball, found in Murchison, unrolled and laid out flat. With Murchison fully represented in design and medium, I had the tattoo artist make one carbon atom bright pink in honor of Pinky. Although it’s only the size of the head of a pin, it means the world to her… and me.”

(Above) Loren, a biology graduate student, writes, “It’s a sketch of the horseshoe crab Limulus, such as a zoologist would make (and with the abdominal segments correctly identified). Perhaps the most magnificent living fossil of all, the horseshoe crab is the survivor of a lineage that extends back some 445 million years into the Ordovician. The four extant species are the only living representatives of the ancient arthropod class Merostomata and the only known chelicerate crabs.”

(Above) Alice writes, “This is an Aztec speech glyph that dates back before the conquest. I’m a linguist, and I believe this glyph embodies the impossible elegance of spoken language as well as the intrinsically artificial and cumbersome nature of written language.”

fitting-foundations

(Above) Mark writes:
“This tattoo is the Zermelo-Fraenkel with Choice axioms of set theory. These nine axioms are the basis for ZFC set theory, which is the most commonly studied form of set theory and the most well known set of axioms as well. From these nine axioms, one can derive all of mathematics. These provide the foundation of mathematics, a field that you can likely tell that I love dearly.”

(Above) Alison, a high-school physics teacher, writes:
“Like many scientists, the wonder of the natural laws of the Universe is where I draw my spiritual inspiration. I also study the religions of the world, and have been fascinated by the reoccurring theme of Creation, Preservation, and Destruction. The Mandelbrot Set (top) represents Creation, with the emergent properties of a simple equation that produces such a rich, complex, and unpredictable fractal pattern that goes on into Infinity. The equation for hydrostatic equilibrium (bottom left) represents Preservation, describing the precarious balance between crushing gravity and expanding pressure inside of stars (including our own) to keep them in a stable, sustainable size for billions of years. The equation describing entropy (bottom right) symbolizes Destruction, simply stating that this fundamental break down of systems and accumulation of disorder either increases or stays the same over time, but never decreases. All three circle around the Delta, the symbol for Change.”

does-the-golden-ratio

(Above) Milad writes:
“I am a Mechanical Engineering undergrad at UC Berkeley and I got this tattoo about a month ago. It’s the golden ratio in the shape of a rectangle, with the ratio of the sides of the rectangle actually being the golden ratio! I have been obsessed with this number since I heard about it in high school, and it is the reason why I became so fascinated with mathematics. The golden ratio is known to be the closest mathematical explanation of beauty. It has been used a lot in architecture, art, and music around the world, and has some amazing mathematical and geometrical properties.”

circuit-ankle440

(Above) “This tattoo is the schematic for the reference point of electricity. I just think of it as the source of electricity. Its really either the point at which you consider voltage to be 0, or in this pictures case, the physical connection to the earth (hence the lower calf). Electronics has been my passion for as long as I can remember, and I feel like this tattoo doesn’t do it justice. So I plan on getting another one to incorporate my passion for electronics and my trans-humanism beliefs.”

cajal440-web

(Above) Anonymous writes: “This is a ‘Ramon y Cajal’ drawing of a human motor cortex pyramidal cell. I am a student of neuroscience and greatly admire Ramon y Cajal not only for his scientific contributions but for the artistic and beautiful quality of his images. This image reminds me of the vast and incredible power of the neocortex, and of the amazing capability of the human body.”

What am I celebrating today?

August 7, 2013

August 7, 2013 has been designated by the US Senate as National Lighthouse and Lighthouse Preservation Day.  Your can read the proclamation here.

From the American Lighthouse Council:

The past and future of lighthouses will be celebrated on August 7, 2013, now federally designated as National Lighthouse and Lighthouse Preservation Day.

The designation came with the unanimous passage of a Senate resolution marking the date as the 224th anniversary of the federal government’s first public works act, the establishment of the Lighthouse Service as President George Washington signed the ninth act passed by the First Congress of the United States.

The resolution was submitted by Sens. Angus S. King Jr. and Susan Collins of Maine, using wording proposed by the American Lighthouse Council. In the House, Rep. Brian Higgins of Buffalo, NY, read the text into the Congressional Record.

I recommend for your lighthouse reading, The Lighthouse Keeper’s Wife, by Connie Small.  I mentioned in a earlier post that I had the pleasure of meeting Mrs. Small a number of years ago, when she was on a book tour and was participating on a panel on successful aging (!) given for medical students. I found her to be charming. Mrs. Small passed away in 2005 at the successful age of 103.

She and her husband, Keeper Elson Small, lived at several offshore lighthouses in Maine between 1920 and 1946, including Lubec Channel Light (1920-1922), Avery Rock Light (1922-1926), Sequin Island Light (1926-1930), and St. Croix River Light (1930-1946).  During this time the lighthouse keepers were all men, but their wives were very much partners in the enterprise.

The lighthouse pictured at the top of the post is Pemaquid Point. It is my favorite, but don’t go there.  It’s mine.

Who do I toast today on tattoo Tuesday?

Andy Warhol was a leader in the pop-art movement that reached prominence in the mid-20th century.  He was born on August 6, 1928 in Pittsburgh.  While best known for his prints and paintings (among the most expensive ever sold) that celebrate advertising and pop cultural icons, Warhol was trained at Carnegie Mellon University and his body of work includes hand drawing, painting, printmaking, photography, silk screening, sculpture, film, and music. An extensive collection can be found at the Warhol Museum in Pittsburgh.

He pushed the boundaries socially, culturally and artistically.  I think he both a leader and a product of social change in post-war America.

Warhol is buried in Pittsburgh at St. John the Baptist Byzantine Catholic Cemetery.  A statue (below) in his honor is in Bratislava, Slovakia.  His parents had emigrated from Slovakia in 1914.

What am I celebrating?

August 4, 2013

On August 4, 1693, Dom Perignon, a Benedictine monk, invented champagne; or so the story goes. Whether or not you believe this version, it makes a good story.  So, on August 4, we raise a glass of something bubbly to celebrate champagne.

Come quickly!  I am tasting stars!
