Figure 1 – The view through bullseye or crown glass. (c) DE Wolf 2016.

I thought that I would go abstract today with an IPhone image (Figure 1) taken through the bullseye of a crown glass window.

Bullseye glass was an early type (first developed in 14th century France)  or process of making window glass, where the glass was first blown into a “crown” or hollow globe. It was then transferred from the blowpipe and then flattened by centrifugal force. The globe was spun out until it was a flat disk, which could be up to six feet in diameter.

The obvious point was that the thick center portion was the least expensive. But from an artistic abstract point of view it creates the most desirable distortions.

Also, if I may make a request tonight (July 19th, 2016) HatiandSkoll is undergoing a server transfer. For about four hours we may lose location fidelity with our name server. That means that the address may not work. If this continues beyond Tuesday morning Eastern Time, could you please let me know. Thanks so much, David

Common tern – Sterna hirundo – beautiful flyers

Last weekend I was marveling at the common terns – Sterna hirundo – at Wood Neck Beach in Falmouth, Massachusetts. These birds are agile fliers and have this incredible ability to hover above the surf and then in an instant to dive down for some morsel (preferably a small fish). I took the image of Figure 1 of such a hovering maneuver.

Here there is the standard flying bird on a cloudy day problem. You are shooting a white bird against a grey sky. there is precious little dynamic range, causing graininess. The photograph is further complicated by the fact that one is shooting with a telephoto through a highly scattering atmosphere. Here the solution is to use the fuzziness to advantage. Don’t call it “fuzzy.” Call the quality of the image “diaphanous” – light, delicate, and translucent. That’s the ticket and the objective all along!

Last Saturday, when I was at Highfield Hall and Gardens in Falmouth, Massachusetts I had missed the Fourth of July by a couple of days. Too bad because I came across the beautiful Allium of Figure 1 in the gardens. They were reminiscent of fireworks and I was thinking, if not the Fourth of July then how about Bastille Day. I can celebrate with our allies the French. So “Vive la France, everyone!!”

I decided to do this image as a deep blue tone to mimic the sky and a fireworks display. This was one of the fun black and white photography manipulations in the analogue days – but has now been made a mundane and simple digital task. The good news is that you don’t have to deal with chemical nasties.

I have actually started carrying three camera with me. First, is my Canon, invariably with some kind of telephoto zoom. Second is my IPhone, which I tend to use for its wide angle abilitities. And third is my little Fuji FinePix digital camera, which I like for close-ups such as the flowers here because it has more pixels and more controls than the IPhone.

It only gets confusing when I get home and have to figure out where all the images are.

A case of “raptor envy”

Figure 1 - Osprey family, Falmouth Beach, Falmouth, MA. (c) DE Wolf 2016.

I have to admit that I have been suffering from “raptor envy.” Over the last few months, I have been admiring other peoples’ photographs of raptors: owls, eagles, hawks, falcons, and buteos. I have been wondering just how is this done, how do you get close enough, and in general I have been suffering from “raptor envy.” In the meanwhile, I have during my walks seen a lot of these birds ever in the distance, and my photographic attempts have been rather pathetic – well maybe not the attempts, but the results certainly. These great birds have always been dark, tiny in the frame, and often out-of-focus.

Last weekend we went to the Great Sippewissett Marsh in Falmouth, MA, and I looked longingly at the ospreys in a distant nesting platform. Later my friend Kip, who knows all secrets Woods Hole, took me to a nesting platform in the marshes just off Falmouth Beach, and to my delight I could get quite close to the nest. So was this the secret?

At first, I thought that nobody was home. Off in the distance a solitary osprey danced through the air in a gyre. Then I saw a little head pop up in the nest and wondered if the gyre might become ire at the insult of my proximity.  I suspect that being dive bombed by an angry bird of prey is not the best experience. I surmise this from the fictional cinematographic experiences of Laura Dern and Bryce Dallas Howard, with velociraptors. Fortunately, my raptors were used to the presence of gawking scientists. Then I saw her closing in and snapped photographs madly. I kept focusing on the eyes as best I could and pressing the shutter. I only had my 70 to 200 mm lens, which may have been best, since with the big lens I doubt that I could have captured it on the fly. Two of my best images are shown in Figures 1 and 2. Gone for now is any sense of “raptor envy.” I finally have my own – Pandion haliaetus.

The osprey is a truly magnificent bird. Also called fish eagle, sea hawk, river hawk, and fish hawk, it is a diurnal, fish-eating bird of prey that can reach in excess of 60 cm (24 in) in length and 180 cm (71 in) across the wings. Psst, that’s almost a six foot wingspan. It is found on all continents except Antarctica, although in South America it occurs only as a non-breeding migrant. Having survived hunting and the ravages of DDT in the 19th and 20th centuries, the osprey has made a decent comeback and is currently rated as “least concerned” as a species. But the precise population numbers are unclear and the osprey’s hold against loss of habitat and pollution must be considered tenuous.

There are a few interesting points to be made about Pandion haliaetus. It was one of the original species described and identified by Carl Linnaeus in his 18th-century work, Systema Naturae,  In the Linnaean taxonomy it was Falco haliaeetus. Second, is the origin of the English work “osprey.” Genus Pandion derives from the mythical Greek king of Athens Pandion II, who was the grandfather of Theseus. Species haliaetus comes from Ancient Greek haliaietos ἁλιάετος, the “sea eagle.” The English word osprey is more obscure but appears to derive from the Anglo-French ospriet and the Medieval Latin avis prede “bird of prey.”

Today I wanted to share another interior image that I took at Highfield Hall and Gardens this past Sunday.  This photograph is a geometric interior shot. Because it is of such concrete definition, I would not refer to it as an abstraction. I think that lying within the nature of our minds is a love of the geometric. Geometry is both soothing and defining of boundaries. There is an appeal to the ordered. It mirrors the stability that we wish of our lives.

I read recently about a couple of parallel lines found on an ancient animal bone and suddenly we had the earliest evidence of humans in North America. In that respect the geometric is “of mankind,” and such is certainly the case here with this chair, the window blinds and their reflections. But it is ultimately the case that we learn geometry, structure, and order from the natural world. A pine barren with a straight and rigid line of parallel trees, a flower, a stair fish, and, of course, the random pattern of the stars that we mentally group into constellations.

Behold the Great Bear and his lesser buddy “The Little Bear,” you say? I can see a dipper, but a bear? It is the product of an over active imagination perhaps – but most significantly it is of a human imagination.

With regard to my photograph, I was taken by the parallel reflections – a physicist’s delight. I love the warm glow and the tonal range. And it is wonderful to be in a museum filled with wonderful art and to suddenly focus instead on the beauty of the mundane and everyday – here the furniture in the library. Specifically it is the most utilitarian of furniture. Yet the Windsor chair is ever a thing of great beauty.

Ascendance

Figure 1 - Ascendance, Jacob's Ladder. (c) DE Wolf 2016.

Figure 1 – Ascendance, Jacob’s Ladder. (c) DE Wolf 2016.

I took the image of Figure 1 this past Saturday at Highfield Hall in Falmouth, Massachusetts. When photographs get categorized, this one would be called an “Abstract” or an “Interior.” But it is more, and I wish there was a category “Myth” or better “Mythic Allusion.” Because, this image and its kin immediately evoke an allusion within our mythic or spiritual psyche. When I saw the scene, I immediately thought of Moses ascending to heaven, denied entrance to the “promised land.” Moses ascends Jacob’s ladder to God.

But it is much more than Moses. The Sumerian goddess Inanna rises up from the underworld to resurrect the world.  Both Jesus and Mohamed ascend to heaven. They too bring resurrection to mankind, and it is the Christian path to climb Jacob’s ladder to be with God.

Ascent is a central theme in Campbell’s “Hero of a Thousand Faces.” It represents a rebirth, literally passage through a second, and this time spiritual, womb. Even the simple act of entering a cathedral represents ascent to a higher plane. We rise from the plane of mundane everyday life to a higher plane of sublime spirituality.

You can see this sense of rebirth by ladder in Figure 1. The ladder leads through a sort of passageway to “the light.” The windows are brilliant, and you can not quite make out their form. I don’t want to over dramatize. But I believe that this kind of photographic theme is immediate and visceral in what it evokes. It appeals to a common set of stories. And if I may be allowed one more, there is Dante’s story of the “Ascent from Hell” (again the Underworld).

“Lo duca e io per quel cammino ascoso
intrammo a ritornar nel chiaro mondo;
e sanza cura aver d’alcun riposo,

salimmo sù, el primo e io secondo,
tanto ch’i’ vidi de le cose belle
che porta ’l ciel, per un pertugio tondo.

E quindi uscimmo a riveder le stelle.”

“The Guide and I into that hidden road
Now entered, to return to the bright world;
And without care of having any rest

We mounted up, he first and I the second,
Till I beheld through a round aperture
Some of the beauteous things that Heaven doth bear;

Thence we came forth to rebehold the stars.”

Dante Alighieri

Sharktivity

Figure 1 – Great White Shark. Image by Terry Goss and licensed under the Creative Commons Attribution-Share Alike 3.0 Unported license.

Let me start with Figure 1. This is a stunning image of a Great white shark taken off Isla Guadalupe, Mexico on August 2006 by Terry Goss. It was shot with a Nikon D70 in an Ikelite housing under natural light. The shark is estimated to be 11-12 feet (3.3 to 3.6 m) in length. Beautiful picture, yes? And there are a couple of points. First, humans live in a largely two-dimensional world. As a result, and second, when we enter the water we are giving up a certain amount of control, where we are not necessarily on the top of the food chain.

This takes me to what is referred to as “Chrissie’s last swim” from Steven Spielberg’s 1975 thriller “Jaws.” Chrissie has been a bad girl, well not really just livin’ the dream of Girls Just Want to have Fun, and is just a bit intoxicated, when she goes for her last swim. I’ve included a link here to the film clip, just to remind everyone of the absolutely visceral terror that the scene evokes. It is a cinematographic masterpiece. The scene is dark and grainy. You struggle to make out what is going on. And, of course, as is standard early in great horror movies, you don’t actually see the monster shark. You just hear Chrissie’s screams for help and her periodic violent disappearances beneath the surface.

Well, imagine that we fast forward forty one years. Chrissie is still running towards the water and shedding her clothes. But in a moment of lucidity and caution she pulls out her cell phone to check the Shark App to determine if there are any dangerous sharks in the area. “Danger, Will Robinson, danger!”

Well that little bit of fantasy has taken one step closer to reality. The Atlantic White Shark Conservancy in collaboration with the Massachusetts Division of Marine Fisheries, the Cape Cod National Seashore, and officials of Cape Cod and South Shore Towns has recently released “Sharktivity.” You can report shark sightings, follow shark activity, and receive shark alerts, as in “Stay out of the Water, Folks.”  This app is modeled after Uber, which certainly creates the image of “Hello, this is your Great White tag CC2015GW16. I will be arriving to eat you in approximately 5 minutes. Please confirm your location.” And then you get to see a little map with a pin at your location and observe a little shark icon moving ominously towards you. Dah dumph.

I’ve actually loaded this on my IPhone ,and it is, for the present, a bit sparse. But, and here, is the really important point, it is representative a form of international connectivity that is not usually discussed. Connectivity is much more than a modern-day Chrissie sharing her selfie with friends on Facebook. It is the sharing of scientific and scholarly information. Hmm, isn’t that what the internet was originally created for? There is a mass of geophysical and other data basically open and free on the internet, and scientists and scholars everywhere are free to use and analyze it.  Apps such as Sharktivity are meant to promote connectivity to nature, much like eagle- and panda-cams. They are meant to connect us, as we were born to be, to our planet and to nature.

With Juno at the juncture of reality and the imagination

July 5, 2016 Switch to toroidal low gain antenna 2:41 UTC

I am the time traveler and I can project myself back in time fifty years, and there I am sitting in the American Museum’s Hayden Planetarium watching the outer planets. The planetarium is dark and cool. It is ever dark and cool. Forever, that is my sensation of space. I am sitting at the very dividing line between the real and the imagined.

July 5, 2016 Begin nutation damping activity to remove remaining wobble 2:46 UTC

This border is where science, both physical and biological, invariably takes us. There is no ambiguity at this nexus. As our reality reaches outward so too does our imagination. We have only to imagine new wonders.

July 5, 2016 Begin fine-tune adjustment of the orbit insertion attitude 2:50 UTC

And, as scientists, we are always imagining. I used to put my desk lamp on the floor and create little eclipses with my globe and a rubber ball. I used to experiment with the umbral and penumbral shadows – ever imagining that I was in that cool dark place called space, where physics ruled everything.

July 5, 2016 Begin spin-up 2:56 UTC

Figure 1 is an image of Jupiter taken, not with the Juno space probe, but with the Hubble Space Telescope. It shows aurora around the Jovian North Polar, so real, right, and more than imagination. Actually it is even more than real, because modern science and human imagination have given us new ways of seeing. To more vividly observe these auroras Hubble uses its Imaging Spectrograph to create deep ultraviolet images.

July 5, 2016 Jupiter orbit insertion burn 3:18 UTC

Scientists know this, but most people just take it for granted. Our eyes which used to be limited to the visible spectrum are now seeing ever so vividly all over the electromagnetic spectrum. We are even mapping other forms of energy. We can even choose an ever so precise wavelength that picks up the distribution of a particular element on a star’s or planet’s surface.

July 5, 2016 Orbital capture achieved 3:38 UTC

So we can abandon, if only for a moment, all of the harsh realities of our world and we can marvel once again, as we did when we were young, at what we may achieve.  We may remember, but really imagine, that it was in 1418 that João Gonçalves Zarco and Tristão Vaz Teixeira discovered Porto Santo in the Medeira Archipeligo. And it was seventy years later that Bartolomeu Dias defied death and rounded the “Cape of Storms” (Cape of Good Hope). Four years later, in 1492, Christopher Columbus discovered the Bahamas, Cuba, and “Española” (Hispaniola). Between 1519 and 1522  Ferdinand Magellan‘s expedition completed the first circumnavigation of the globe. Almost another century would pass before the settlement of Jamestown in 1607 and the establishment of the Plymouth Colony in 1620.

July 5, 2016 Terminate insertion burn 3:53 UTC

This timeline is sobering. Even factoring in the fact that we have come to take for granted the break-neck pace of our world and the technology that drives it. We arrogantly assume that we can move faster. Inevitably discovering new worlds takes time.

July 5, 2016 Begin turn to sun-pointed attitude 4:07 UTC

But last night, as Juno ended its 1.8 billion mile journey, inserted itself into Jovian orbit and oriented itself so as to be able to absorb energy from the feeble sunlight at that distance (~1/25th that at the surface of the Earth), I was taken back in time to those days in the Planetarium fifty years ago and I also traveled forward in time to imagine where we will be fifty years hence.

July 5, 2016 Switch telecom to medium gain antenna, begin telemetry transmission 4:11 UTC

As signal was received last night at NASA’s Jet Propulsion Laboratory the scientists erupted into cheers and applause. Scott Bolton, Juno’s Principal Investigator announced that “We just did the hardest thing NASA has ever done. That’s my claim.” During the next two years, before Juno plunges into the planet, we will learn a lot about the planet and about the origins of our solar system. Right now we can only imagine. The words of Tennyson come ever to mind as we contemplate the border between reality and imagination,

Yet all experience is an arch wherethro’

Gleams that untravell’d world whose margin fades

For ever and forever when I move.”

Alfred, Lord Tennyson, Ulysses
