Friday beauty posting

Missing finger syndrome is when your amputated finger itches. Last Friday I had missing work syndrome.

On our son's graduation day, I was fighting a strong desire to grab my computer and start solving a work task. It was completely unnecessary: my half-year review was already done, and all my tasks for the day were closed too.

I'm trying to treat this illness in Montenegro. In the photos, you can see me climbing this beautiful island.

Jets are approximated

Finally, I conducted the experiment and analyzed the results. The curves were fitted during quite a long session with Claude.

One thing I would do differently now: mark the jets with different colors from the very beginning, and do the same for the hole positions. When Claude can infer the whole idea behind the scene, it is surprisingly hard for it to figure out the precise boundaries of objects.

In the PDF, you can find the full derivation of the parabolic trajectory with a correction for the camera tilt.

As a bonus, there is an old but gold joke about a scientist's perception of the whole world.

Armenian spinning top Quiz

Let's get dangerous! (c)

I'll try to send (or give, or whatever) an Armenian spinning top to the person who gives the best explanation of the difference between the left and right pictures.

I solemnly swear that both pictures were done with the same camera, at the same place, the same spinning top.

Let's set deadline for explanations as 13.00 MSK, 13 Jul 2000 + 2*13.

Water jets - navigation

A thought here, a physics puzzle there... One by one, I collected quite a nice series of posts about fluid dynamics.

It flows from the law of conservation of energy to a DIY tower printed on a 3D printer.

Enjoy your ride down the torrent!
