Previously, it was discovered that in the oscillatory mode the aerodynamic support of the air can increase up to six times equal to the blowing data in the wind tube. In addition, it turned out that the direct flow of asymmetrically moving bodies in the country cannot be easily explained by Newton’s third law, since the flow occurs in the direction where the body moves towards the middle.

Further experiments confirmed this, and on its basis a hypothesis was put forward: this type of turbulence (swimming fish and bird flight) vicoristic energy of the collapse of the vortex wake. In fact, the thermal energy of the superfluous medium (Brownian ruch) is the result of the direct process of self-organization of molecules in the vortex. This reveals a new look not only at vortex dynamics, but at fundamental physics as a whole.

However, this will require further research, and the problem of creating an efficient and wear-resistant drive remains unsolved. My opportunities not enough for this.

Hey fellow horologists out there! I built a functionning clockwork out of trash, in Glashütte / Saxony. I call it the "Glashütte Trash Clock". It runs for about half an hour, it uses a paperclip-escapement, it has a gong and it also features a random complication.

There's a write-up on my website, explaining the project's background and how I made the clock, step by step.

We’re producing IPE100 European I-beams for a project in Colombia. This shot is our workshop cooling bed right after hot rolling. The profiles sit here to slowly cool, then go through straightening, dimension checks, surface inspection, marking and bundling.

Location: Budapest, Hungary (Southern Railway Belt expansion project)

Structure: Steel railway bridge over Soroksári út arterial road (will also serve as the platform level for the future Közvágóhíd station)

Technical specifications:

Weight: ~2,500 tonnes

Components: Assembled on-site from 120 separate steel segments

Dimensions: 109 meters long, ~20 meters wide, 12 to 19 meters high

Installation method: Traditional cranes could not be used due to space constraints. The structure was aligned and pushed into place using 176 Self-Propelled Modular Transporter (SPMT) wheels and heavy-duty hydraulic jacks.

Retiring a humanoid robot fleet can pose an unusual problem: how do you dispose of the machines without exposing proprietary components? Figure chose to melt most of its F.02 fleet at a Finnish foundry, training the robots to jump autonomously into the furnace. That turned a disposal task into a control challenge, requiring precise jumps despite extreme heat and electromagnetic interference.
