Oculus Rift

I built myself a PC some time ago to run Hauptwerk, especially the Rotterdam organ, which meant a very quiet case and cooler, an I7 4790K and 32GB RAM. When I stumbled over the Microsoft Flight Simulator, I also built in a decent graphics card (Geforce 1070 with 8GB). On the advertising pages of the graphics card driver was information about VR games, so in the aftermath I had an eye on it. More or less unplanned, I decided to buy an Oculus Rift in late November, together with The Climb.

Virtual Reality Experience

The first conclusion: VR is just cool. When I was in Trier for the Christmas shopping, I was really wondering why the customers in the media markets do not carry these things out on a pallet-wise - instead, it seems that the VR glasses have not yet reached the mass market. The Oculus Rift is already pretty mature and affordable with 449 €, a good monitor costs about the same amount. During the setup, I blocked myself first a few days because I did not find the HDMI output on the graphics card and thought it had four display ports. Only after the newly ordered HDMI on Displayport adapter did not work, I've read through the description again and found that behind the third same-looking plug of the graphics card actually hides a HDMI. The setup was pretty straightforward and the introduction is just cool: the touch controllers are presented as the virtual hands, they are exactly where your hands should be and do exactly what your hands do - grab, point ... and everything in 3D.

Blöder Perfektionismus

I don't know if I it's possible that i have the worst possible combination of personality traits: The analytic-logical side of the INTJ combined with the perseverance of the perfectionist (Enneagram 1). Worst in the sense of: No one else is that freaky. Anyway, that's how it feels in these days. Example 1: This photo

As with many other things that I do, this photo also has two purposes, which is simply more efficient: on the one hand the photo as such, on the other hand the pictured 3D printer. I wanted to discuss the latter for the same reason and I saw the potential for a good photo, then I wanted to make one. Click once with the phone would have taken 5 seconds. This photo about 4 hours.

I cannot stand it when ...

... stories are nonsense. I do not watch that much TV, but lately Interstellar was on TV, and at least the soundtrack is famous. Unfortunately I did not like the story at all and on a closer inspection there are a lot of very big logical mistakes. A key element of the film is time dilation, which allows astronauts to outlive all the people remaining on Earth. Unfortunately, this is physically impossible, especially the scene where they land on the planet orbiting the black hole where minutes turn into years. In principle yes but so - never. The first big faux pas is when the sun is shining. I beg your pardon?! Since when does a black hole is shinning ?! Then I calculated this out of pure curiosity. Yes, a time dilation by a factor of 10,000 is possible, says the General Theory of Relativity. The only question is: how strong has the gravity field to be to obtain such an effect? I have misplaced my calculation, but the result was similar to the surface of a neutron star. With that we are far, far below the Roche border where a solid body loses its cohesion due to the tidal forces, means: Only the gravitational difference between the head and big toe would simply atomize a man, if that's enough ...
