Glass
Different panes of glass of various age, each reflecting the surroundings in their own way, but each correctly and not disformed showing the curtain behind them. Glass that is older, is more irregular in thickness. That is because of the way it is made. It is an urban legend that glass is a fluid and therefore changes shape as it gets older, but this is only a legend and not true.

Turning wheel
This is the turning wheel of the Helpermolen. With this wheel you can turn the wings towards the wind. The white paint of the turning wheel is as bright in the photograph as the sunlit wouden fence. Still we clearly see that the spokes of the wheel are white and the fence brown, so darker than white. A drop in brightness of an object due to shadow is automatically adjusted in our perception and so this is prefab knowledge in our brain on the effects of light.

Amsterdamse School
This fantastic building in the style of the "Amsterdamse School" at the Zuiderdiep in Groningen was designed in 1928 by Sieb Jan Bauma. The rooftiles curve down to an almost vertical orientation. The building has a strict beauty.

Hurdy Gurdy
A hurdy-gurdy player. The accents in the music are placed with his right hand, by at each revolution of the crank giving small jerks from the wrist. This goes together with the choice of the notes with his left had. An old an difficult instrument to play, but when done right, it sounds like a small orchestra.

Catenary
A catenary curve is being formed by a chain with equal mass distribution. No part of the chain carries the information of the catenary curve, but the parts together always are able to form the curve. The raindrops that fall in this image are not coupled together and so the only thing they can do is fall down. The brandnew students that visit the introduction week of the new academic year are also more than the sum of their parts, due do their internal coherence and their coupling with the environment, including each other.

Weston II
The Weston II exposuremeter, made in England in 1946. Still has an accuracy within 1/3 stops and beautifully made. Always reliable, since no battery is needed and with a very solid construction.The units on the white scale is in candles per square foot. The film sensitivity is in "Weston Speed" in which 80 is equal to 100 ISO.

The electronic city. Strict layout and function go together, just like in the map of a city. Recored in 16 exposures, mounted with software. It seems as though the object is much bigger due to the fact that everything is in focus. So that is the reverse effect of this image: (click). Again our idea of sharpness and size has been shaped by the history of photography.

Franz Joseph Gall's Phrenologie
This is the phrenology of the head of Franz Josepgh Gall, drawn onto the skull of an unknown Swedish man. Frans Joseph Gall was the founder of the phrenology, a method that relate mental capacity of humans with little bumps on the head. The expression "he has a math bump" comes from this approach. Nowadays we know the phrenology has no scientific basis.

Bass Pipes
The three largest bass pipes of the organ of the Martinichurch in Groningen, built in 1692 by Arp Schnitger. It is a 32 foot organ of which the lowest note has a frequency of 16 Hz, which is in het infrasone area. This means that the note can not be heard very well, but felt all the better.

Watt governor
This is the Watt centrifugal governor of the steammill near Winschoten. The two spheres are mounted to a rotating axis and when the engine speeds up, the spheres move outward due to the centrigual forces and the steamvalve is being pulled closed. When the engine slows down (for instance due to an increased load), the valve is being pulled open. In this way a near constant number of rotations per minute is achieved, which can be set by the weight with the wingnut on the left of the governor.

Wind turbine
A modern three bladed windmill can deliver the necessary energy for a farm. The mill orients itself towards the reigning wind direction and adjusts the angle of the blades around their length axis in order to obtain the optimal rotations per minute for the generator to produce energy. The sound of the blades in the wind suggests that quite a bit of energy is still lost in turbulence of the air.

Serotin Bat
A Serotine Bat (Eptesicus serotinus) in the city. This bat species flourishes well here and makes its loops between the trees. This exposure was made with a strobe flash that gave eight flashes during 0.2 seconds. At a distance of four meter, you don't hear anything of its flight. Most birds can not match that silent flight, perhaps only some owl species. In the fifth frame the left wing (we see the animal from its belly side) is held back a bit more, giving the right wing more lift in order to start a turn to the left.

Hard Saddle
Often, it is nice to sit on a soft surface, but not so when sitting on a bike saddle. A soft saddle gives lots of complaints because you can not move freely. On a very hard saddle, like this carbon saddle, you sit on only two points of your pelvic bone and nothing gets compressed, also thanks to the furrow in the middle. Ofcourse those two points need to get used to it, but after that is wonderful to sit on a sadle as hard as a piece of stone.

After an extreme cloudburst (the rate was 160 mm/hour, while the yearly precipitation is 760 mm), the manhole covers from the hospital grounds were lifted by the water and within a short time half a meter of water filled the Oostersingel (which has been a street rather than a canal for a long time!). At first sight you would think that since metal sinks in water, the covers should stay in place, but when the upward pressure is high enough, the cover is lifted anyway.

A.Viswat
On the cabin of this ship, we can read the city of origin, the owner and the weight of the ship. The last measure can in the mean time have become a bit less, due to rusting of the ship. Although initially rusting steel becomes heaver (due to binding of oxygen from the air), it still looses weight later on, due to shedding of rust particles from the steel.

Like a glove
Going very fast on a bike is only possible when the size is right and the adjustments are done with care. That has to do with aerodynamics, but als with the conditions in which muscles are able to generate power: at the right length and the right shortening velocity. All together, a bike that is well adjusted feels like an elongation of your own body. Here a snapshot during my training round click here.

Balance artists
We are all balance artists on our bicycle. The balance comes from the law of conservation of angular momentum of the rotating wheels (much like a rotating spindle can stay upright), but more importantly from the shift of the point of contact with the ground, which moves from left to right under the center of mass of the cyclist-bicycle combination by the steering actions of the cyclist. This generates a lateral force that pushes us back upright when we are about to fall sideways. That works just like balancing a stick on your finger: you move your finger from left to right under the middle of the stick.

Coltelleria
A very rare optical effect: A advertisement board in Florence (upper panel) has been mounted under tension, creating two hollow parts, left and right from the middle. The middel is almost flat. The hollow parts function as hollow mirrors, inverting the image from the golden letters of the board, which was already inverted because of the reflection. Consequently we can read the letters in on the street (lower panel). The middle part is still inverted by the simple reflection. Between the three parts in the image, nodes appear, which are projections of the sun due to just the right amount of concavity. That is also true for the ends of the image. And so four images of the sun are formed and three partial images of the advertisement board. For the rays forming the effect, see here. None of the pedestrians noticed this remarkable image on the ground.

Reflections
Reflections differ at least in two aspects form the three dimensional original: 1] The angle under which we look at the oringal differs from that of the reflection, and so the reflection differs in the photo. Look at the anker, which rests onto the red-brown rim in the original, but stays well clear of it in the reflection. 2] Highlights are different due to the pathway of rays. Look at the two highlights in the reflection, that are absent in the original. In this way it is often easy to distinguish a fake reflection created in photoshop, from a real one.

Crossing ripples
Ripples in water exist of running waves of energy transfer. The water particles only move up and down and transfer that movement to their neighbours. It is possible to have two waves crossing each other at an angle without influencing each other, like in this picture. The same can be shown for waves occurring in a crowd in a stadium. When you start a wave at two ends in the stadium, they simply cross eacht other without extinction. This in contrast with running action potentials in nerves: when they meet the extinguish each other.

Mouth Organ Man
This streetmusician in Groningen, calling himself Mouth Organ Man, told me that he discovered when he was 55 that he could do four things at the same time, as a bricklayer and so he became a musician.

Spiderweb cracks
When a piece of safetyglass is hit at one point, it can break, but because of its composition, the pieces stay in place. This way you can see a spiderweb pattern and there is an explanation for it: The cracks are formed at right angles to each other because of the way the main cracks change the tension in the glass. A spiderweb is constructed in such a way that none of the wires are tensed too much. (Yuko Aoyanagi and Ko Okumura. Simple Model for the Mechanics of Spider Webs.

A gigantic gear of 76x14!. Everything is optimised to stay as close as possible to the back of the derny rider: saddel moved to the front, elongated handlebar, front fork turned backward and the front wheel made smaller. A fantastic shop!

Quad ESL 57
In 1972 I heard sound coming from a loudspeaker that was so real that I was truly surprised. It was the Quad ESL 57 and they had put 10 of them in a row on the podium of a concert hall, playing classical music. The loudspeaker does not have an box, but a large membrane that is moved over its full surface, just like the air moving through an open window. The sound convinced immedeately. As soon as I could afford it, I bought a pair of Quad ESL 63 loudspeakers in 1984 and they are still in operation. Everyday completely color free voices and music.

Book of Sand
"The Book of Sand" appears high on my list of literature. When I read it for the first time, it suddenly disappeared and I found it back, months later: it fell out of the sleeping room window en had been rained wet and dried up again between the plants. The book became twice as thick, but was still readable. Because sand got stuck between the pages, the book literally had become of sand and in that state I have kept it ever since. The thicknened paper fibers and bumpy pages give the impression of a sand landscape and that fits so well with the magic realism of Borges.

The snow encloses, while melting, less and less air and so fewer reflection surfaces are present in all kinds of directions, so that the sky light is not so nicely diffused anymore and the snow loses the ability to reflect it fully. The icy snow now starts to work like little lenses and mirrors at the same time. The skylight is now mixed with the dark wooden bench underneath.

Wineglasses
Empty wineglasses show something about optics: since the innerside of the glass has a higher curvature than the outside, it acts as a negative lens. When you look through the glass, the world appears smaller through two negative lenses. This effect is stronger when the wall of the glass is thicker and/or the glass smaller.

Fifty!
Karen celebrates her fiftieth birthday today. Congratulations! (The colors come from interference of twee different reflecting rays. At different places on the label, the distance travelled of the rays vary, and thus different colors, or wavelengths are amplified, much like the colors occurring on a CD-Rom, on a soap bubble, insect eyes and some fish eyes)

Regulator House
This is the regulator house of the former gas factory in Groningen in south eastern wind. The gas factory has been removed, but the house (built in 1892) has been preserved. The round window contains a Davidsstar and that has a direct relation with the former Jewish cemetery called "Jodenkamp" next to the factory, which was moved to the Moesstraat.

First microscope

The producer TOWA is still active. Here a link to a portrait of me from 1963 with the same microscope.

Snow on a black umbrella can be observed well and then it appears just how big the snow crystals can become. Nearly always hexagonal (six-sided symmetrical) when it is not too cold. They get their form due to the formation of weak bonds between water molecules as they freeze: equilibrium between repulsing and attracting forces. It all starts hexagonal very small and can keep on growing for quite a while in the right circumstances.

Orange Flag for Amalia
The orange flag is flown from the Martinitoren for the 6th birthday of Princess Amalia. The physics of the ripples in the flag is very complex, but dominated by the mass of the cloth and the elastic coupling due to the fabric: very time a piece of cloth is blown sideways, it is pulled back by neighbouring cloth. The aerodynamics of a flag can be fully simulated with mathematical models. But even without these models the flag is interesting to see when it moves: never twice the same.

Eye in colorprint
Color prints in books consist of four color rasters, cyan, magenta, yellow and black. By varying the size of the dots of the four layers, the endcolor is mixed when looking at it. Therefore it is important that the color dots each have their own place, hence the rasters. Else the colors would not add, but subtract from each other. The distance between adjacent dots of the same color is called the "dot pitch" and determines in part the quality of the print. The is pitch here is 0.14 mm, which is 180 dpi. This is the left eye of Milla Jovovich, photographed by Bettina Rheims and reproduced on page 159 of "PhotoBox", published by Thames and Hudson.

Candle flame
The flame of a candle has an enormous range of color temperatures from 2.000 degrees Kelvin (almost red) to 10.000 degrees Kelving (deep blue). This is the case because of the different circumstances in which the candle grease burns. The light of the candle is given by glowing carbon particles. In the flame there is not sufficient oxygen for complete combustion, but at the base of the flame fresh air is attracted and the temperature reaches the highest values en we see blue light. The funny thing is that we associate blue often with "cool" and red with "warm, but in actual temperature, it is the other way around.

Leaves at the end
At the end of automn the leaves are falling from the trees. Right at the end of the branches, sometimes leaves are still present. That is odd, since right there the wind is blowing with higher force. So what is going on? The explanation is that the tree drops its leaves by using a plant hormone that is made at the base of the stem and is being transported to the end of the branches, where it arrives the latest. Therefore the leaves may still be present, like in this case with willow trees.

Caustics formed by a glass of water
Caustics are formed by a glass of water just like lenses in a camera do. The difference is that the image quality formed by the glass of water is really much worse, but the geometric curves so much more interesting.

Dutch sobriety
The window of a houseboat. Dutch stinginess is part of it: less textile, so that there are no folds, only printed on one side (the inside is most important since the boat owner is looking at it most of the time) and painted with a number of paint drops on the window. A pleasant sight, those house boats on the canal.

Bee stuck in water
When we get wet, it does not limit ourselves that much, but a bee or other insect that gets wet has an enormous problem: more water can be attached to the body than the insect weighs. On top of that, forces that keep the drop togehter now also keep the insect stuck to the wet surfae. Also, the insect cools down. Now it could warm itself up by using its flight muscles, but that only works if they can still be operated.

Blue books
This little shop with second hand books has a window with discoloured blue books. That may have happened because the entrance tot the window is blocked with more recent books (partly not discoloured), so that the window did not get a refreshment of non discoloured books. It may be a nice idea to try and buy a book from that window, but I think that (understandibly), the owner of the shop would resist selling it to me. The shop looks really provincial that you see more often in Groningen. The discoloration in the direction of blue is caused by two factors 1] The blue pigment reflects the light rays with the highest energy content, which are the blue rays. 2] The glass of the window blocks the ultraviolet rays, which carry an even higher amount of energy. The other pigments are damaged by the light rays that do go through the glass.

Cracks
This is an old ship in the Noorderhaven, named "Gouwzee". Over the years its condition deteriorated, but for a photographer that is interesting. Cracks appear in the coat of paint and when you look carefully, the cracks are nearly all meeting at right angles to each other. That is cased by the tensionlines after the formation of a crack: they run parallel to the crack (a iso tension line can nog cross a crack, since the tension in the crack is zero). New cracks form at right angles to the iso tension lines and so form at right angles to other cracks. You can see the same patter in glazing of pots (see klik for instance). The funny thing about the StreetView image below is that exactly the part with the cracks is blurred out by the software, which normally blurs house numbers, faces and car plates.

Incabloc
In order to move further into the Unitas movement (for an overview see 0005), here an image of the IncaBloc of the movement, an important extension because of the fact that the springlike suspension of the jewel (that purple part) takes care of a shock so that the axle of the balance wheel does not break. You can see the principle here: klik and here klik. This picture is also the result in the quest for the best compromise between resolution and depth of field at a magnification beyond four times in the focal plane.

Fountain pen and ink
98% of the text that I write is done with a keyboard, but I still write with a pen also, especially when I want to formulate new ideas in the form of tekst or figures. It is just as if I am closer to expression on paper than when I use a computer screen and I get better results. In 1983 I bought this pen at Harvard Square. It broke in half once when it fell (the handle was replaced without cost) and twice the nib was replaced, once because it was worn and once to get another width. The ink bottle is older and has a glass marble in the neck so that filling the pen is easier: the marble stops the ink from flowing back after you fill the neck by tipping the bottle with the cap on it. I fill the bottle with home mixed ink: the thickness is important when writing on lower grade paper and the ink should dry up in a neutral black color in my opinion.

Spilsluizen foreshortened
Today a dark day with drizzle. In between some bright spells. This is Spilzluizen from a distance (waited for the pedestrian) with an equivalent of 450 mm fullframe, that is long. The depth is being foreshortened and you can see three bridges with ships behind them in the Noorderhaven close to each other, while infact they span a distance of 600 meter.

This is a house in Groningen that has been deserted for a very long time. Several decades. The lace curtain has become almost black with dust. You can not look into the house. The name on the door is nicely painted and there is a recent lock on the door. A more recnt doorbell is clean: it is pressed regularly. Fascinating!!

This is the Unitas 6497 movement, developed around 1950 for pocket watches. You can build a larger casing around it for wearing on the wrist, the movement fills the whole casing. If you find out how to put the watch at night during sleep, an incredible accuracy can be reached of less than 5 seconds per month (klik): during the day you lose a second and during the night you gain it back due to the lower temperature and orientation of the movement. Fascinating that a mechanical watch that is acturally worn can be so accurate....
