Astrolab

Some years ago I used an older verion of blender to animate the usage of an astrolab together with some astronomical explanation how it works.
Differential Analyser Loop

Differential Analyser
Просмотров 14 тыс.12 лет назад
The principal usage of a differential analyser is shown here. Two integrators are connected to each other to perform the differential equation ydotdot = - y. One solution is y = sin(t) and ydot = cos (t) which forms a perfect circle. This example was used to test the precision of differential analysers.

    Dude, you explained me the workings of the astrolabe without any commentary! Amazing, just with visuals! Thanks man

    Maybe the Differential Analyser made from Meccano seen at ruclips.net/video/niiCtEFJGYQ/видео.html may be of interest.

    wow awesome ! are you willing to upload the blendfile to blendswap or redo it with a (volumetric?) spotlight to show how it DOES work for spheres , by visibly showing the shadow projection lines from sphere to flatness ? (see my shadow projection playlist to see what i mean) -I don't like this genious analogue computer being associated with flat earth theory ;-)

    This video is 100% lie, the Astrolabe will only work on a flat plane. this is not how it works at all.

      False, it would work on a globe or flat earth. All this tool does is map what positions the stars and sun are based on the time of year. The angles the stars are only line up with a globe

      @Danger Manilla Light travels infinitely. So you can see that far since the light from the stars is not traveling through an atmosphere before it gets to earth. Light only stops when something blocks it or absorbs it. And false, not all stars are in the same exact position, the north star was a different star recorded by the Egyptians. Your forgetting scale, it will take thousands of years for the stars to change positions. It will take literally 302,000 years just to move one light year Put two basketballs on the ground about 10 ft from each other, and walk about 400ft away from them. Now take a step to the right or left, how much of a difference do you see in their positions realitive to you? That's equivalent to the earth in 5,000 years. So who is mentally arrested? The person who accounted for scale and distances? Or the person who made assumptions that the stars haven't moved at all, that light cant travel that far, or that we should see completely different constellations and star positions by now. Your arguments are built on nothing but misunderstanding scale and assumptions.

      @Danger Manilla Uh, where do you grt that? No, because depending on your distance to things the intensity of light gets smaller, as the light is spread out more. Draw a circle, and lines coming off of it evenly spaced apart, try doing about 50 lines. Draw a smaller circle about half the size of the first right next to it. How many lines are hitting it? Now draw another, but this time as far as you can, now how many lines are hitting it? Light spreads out over distance, not that hard to understand. Also, light can be blocked by other objects in space. The basketballs were an illustration of how moving a tiny bit doesn't affect positions lol. Your really dumb if you don't get that. Someone doesn't understand down = towards the earth. Lol. There isnt a unified east or west on your flat earth so what is your point? Look at a globe with longitude and latitude, north is towards the north pole along your longitude, south is the opposite direction. East and west are just going right or left from your longitude.

      @Danger Manilla And? The point of my comment was about scale and size, and stars moving. The thing about the north star being a different star is true, the Egyptians documented the stars positions, and they have changed slightly over time.

    Dig this "The FLODAC", patent 3190554, A digital computer that used air to compute! If Babbage had this tech the pipe organ folks could have made his "engines for him and Lovelace could have invented COBOL!

      He needed Meccano, see ruclips.net/video/niiCtEFJGYQ/видео.html - I just though, what could Alan Turing, have done with it? -- He was one of the people involved in making machines to break the German Enigma code during WW2
