No Point
After I returned the Buck knife to the shop because there where many hair cracks perpendicular to the cut (see the photo of 18th of September 2020), it came back. They have grinded away about 2 mm, making the hair cracks disappear. But the point of the knife has disappeared also, making part of the functionality disappear. And that is a point to me.

Catching Flies
You can catch flies with a wineglass and a picture postcard. Place the glass slowly and gradually over the fly. They don't see many details, but they see movements very well and sense air movements extremely well. But this way they are suprised and you can place the fly outside, since they are fantastic animals, that don't learn very much from experience.

Standard
When comparing these two try squares, there is a difference in what they indicate as a right angle of 90 degrees and there is a difference of 2 mm over 400 mm length. So what is the standard? Fortunately, there is a bar of 1 meter long in Paris, while we can construct an angle of 90 degrees, to know which of the two try squares we will use in the future. (In practice we do not need to go to Paris, we just take the average of a number of tape measures and rules in the house, to get an approximation of what 400 mm should be).

Newton
An instrument to measure force in Newton. When you hang a weight from it and je divide the number you get with what a scale would show, you get 9.8. And that is because the mass of the earth pull with a certain force at the mass. But if you apply it on the moon, you also get 9.8, while the moon really has a much lower mass. On the other hand, when use use this instrument horizontally on earth or on the moon, you get the same result when you apply a pulling force. So I'll just keep it at hand for measuring forces, rather than weigh something.

March 2020

Moon
When watched with the naked eye, the moon only covers 30x30 cones in your eye so that gives very few details, but a lot of room for fantasy. And that is where the face in the moon comes from, as depicted here in an old clock.

Measuring Colors
To measure colors you need an expensive instrument (almost 10.000 Euro). But with a MacBeth card with powdered pigments, which have been calibrated, you can photograph the object together with the the card, to measure the RGB values of the object. The correct RGB values minus the measured values in the photograph form a vector filed in RGB space which you can interpolate for the color you measure in the photo of the object. After converting to CMYK profile of a known type, you can get printed colors of the objects as you have measured in this way. Everything is calculated with homewritten MatLab software from the values collected from the photograph. The software finds the color patches by itself, you just need to click on the color you want to measure.

Fruitfly
A fruitfly is very small, about 10x smaller than a housefly. That is why he has fewer facets in his eyes, since the diameter of a facet limits the resolution of the image. In total they have fewer "pixels" (about 150 in each eye) and so they see less. Therefore it is easier to catch them.

ISS
The International Space Station passed by. Now I aimed my telescope at a predefined point and photographed at the highest magnification.

Radiometer
A radiometer in the morning sun. The black sides of the vanes absorb photone, while the reflecting sides reflect them. The heating up of the air at the black sides increases the air pressure, driving the radiometer. When you place the radiometer in the freezer for a short while, cooling it down quickly, the direction of rotation is reversed, due to the black body radiation at the black sides, which lowers the temperature at that side, reducing the air pressure.

Rolling Shutter
Modern camera's can have a silent shutter, by reading the pixels row by row. That gives an effect that is called "rolling shutter" and can be seen here in a photograph of a signpole seen form a speeding train. The same can be seen in old photographs in which a slow slit shutter was used: I made this animation to explain it click . My camera reads from bottom to top. The sense of speed is better in the image of the old camera, so it is a good advice to use the modern camera upside down.

Robert Hooke already observed this in the seventeenth century, while he did not know anything about the wavelike nature of light.

Speed of Light
Measuring distance with a laser is done by measuring the speed of light in air. That speed is about 299700000 meter per second. In water the speed of light is lower, about 225000000 meter per second. And so it takes light about 33% longer to cover the same distance. When you place a bucket of wat er between the meter and the wall the distance shoud be indicated 33% longer by the meter. And that is exactly what the meter indicates: 292 mm is 33% longer than 219 mm.
