Amilcar
Max Verstappen won today on Zandvoort at the Grand Prix. A long history of racing cars contains for instance this car, an Amilcar CGS from 1923. The engine power is 30 hp and the top speed 120 km/h. The power of a modern Formula I car is about 1000 hp, so more than 30 times as much, but the top speed is only slightly more than 3 times as much. And that has a lot to do with air resistance. When you want to go 3x as fast, you need 3x3x3=27 times the power, which is well in agreement with the factor of 30 mentioned above.

75 cl
It is hard te believe that both bottles contain 75 cl of wine. The small bottle comes from Chili, the large one from the south of Italy. When they are empty we can measure whether the Chilian bottle gave us less wine or the Italian one more than indicated. In theory it is possible that both contain 75 cl since the thickness of the glass can play a role.

Nearsighted
After observer riders of the Felyx electric rental scooters in the city of Groningen, I can only conclude that they are near-sighted. Only on their smartphone they have things in focus. Or perhaps it is part of our time frame that we have created together.

Crane Fly
A crane fly contrasts nicely against the blue plaid. Those bulbs behind the wings are halteres that move in antiphase relative to the wings and used to be wings. Now they serve as sensors: as soon as the insect rolls during flight, there is a difference between the right and left bulbs due to the movement, which is why the insect can fly at an angle, which is in constrast with dragon flies, wich have 4 wings.

Made it
Made it: a mathematical model of 13 joined soap surfaces finds the same minimum as in the experiment. The middle square is 21.4% of the side of the cube, which fits the experiment. Also the curvatures of the boundaries match. The method that is used is to make the sum of the principal curvatures zero at every point in the surfaces. That also provides the minimum surface area of the surfaces, just like the real soap films do due to surface tension.

Soap films
A set of soap films hanging in a wire cube minimize the total surface area. If you assume that the surfaces are planer, the square in the middle would be 7.3 % of the side of the cube according to my calculations. In this experiment it is about 21%. The difference is due toe the fact that the surfaces are not planar as can be seen in the image: the contact lines are curved. The square in the middle has curved sides because of this. The key to improved calculations comes from the Belgian physicist Joseph Plateau: the surfaces meet at an angle of 120°.

Simplest Telescope
The simplest telescope was invented in the Netherlands by 3 opticiens in 1608. This is an example of the simplest telescope you can make. A larger front lens with a longer focal length and a smaller lens as eyepiece with a shorter forcal length. The magnification is the focal lengths divided by each other, in this case exactly 2x. The great advantage of such a large front lens is the ability to capture much more light than the human eye.

Tracks
Bicycle tracks in the snow betray that the front wheel covers more distance than the back wheel. This is due to the balance of the rider and the way the bicycle is built. If the back wheel would turn against the direction of the front wheel when turning the handlebar, the wheels would cover the same distance and you would only see one track. (identifying the track of the back wheel is easy: it overwrites that of the frontwheel, unless the rider was going backwards, which is highly unlikely)

You can catch flies with a wineglass and a picture postcard. Place the glass slowly and gradually over the fly.

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.

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.

Looking
When a housefly looks at you, it does not see you in great detail, but it is very sensitive to movement. Between the facet eyes you can see an extra small eye that is functional in that respect. Also the hairs are very sensitive to air movements. So you catch a fly with a large glass that you slowly place over the fly and you slide a card onder the glass.

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.
