The Astrolabe by Wilfred de Graaf

“One of the most widely used astronomical instruments over time is the astrolabe. Astro- labes were mainly used for two purposes: for astronomical observations and calculations, and for astrology. In this treatise we focus on the astronomical purposes of the astrolabe.

The astrolabe is a flat and portable instrument mostly made of brass on which the po- sitions of the sun and some of the major stars are projected relatively to the observers horizon. Its mathematical principles date back to Greek antiquity. The principle of stereographic projection was known to the Greek astronomer Hipparchus of Nicaea (150 B.C.). Although it remains uncertain, it seems probable that Ptolemy used an instru- ment like the astrolabe. Certain is that he wrote a treatise on stereographic projection. Unfortunately no Greek astrolabes have survived.“

There are IIRC, 3 floods in Genesis.

The original is on archive.org.
I found a slightly larger one, which I updated with gamma, contract and saturation, rescaled it, denoised it and sharpened it, as much as I could. I don't have hardware to do an AI de-oldify or so. Still.... much better than the original, and the sound has been improved as well. I added SRT and SSA subnoscripts so other people can translate it for other languages too...
Enjoy. A truth speaker for sure.

Of course you can. AI to the rescue.
One (NottaAI) to transliterate into german text.
Then DeepL AI to translate into English.

Then use Speechelo AI to voice it in English.

Some tools to reflow the subs, and Audacity to time the synthesized speech to the video length, redo the pitch... Et voilà... 😊
