Page 78 Heloise and Abelard fell in love, and she gave birth to a son whom they named Astrolabe.

@LATIFAHMOHDNOR-zy1mq Ай бұрын

Her uncle Fulbert, at first enraged by the relationship between Heloise and Abelard and later somewhat placated by their marriage, finally decided that Abelard had abandoned Heloise at the abbey and had him emasculated.

Thank you for explaining the Astrolabe. I was taught by my teacher that the Astrolobe is ancient technology, possibly millions of years old and has always been here on earth. It is an off-grid mechanical device that directly corresponds to the movements of the illuminaries above in the skydome -- and a proper Astrolobe positioned to your GPS coordinates, is a tool to be in correspondence in perfect mathematical synchronization to the stars/heavens above. A tool of "As above, so below". The stars are you looking back at you and ornaments in the sky for your enjoyment, companions at night, and co-pilots during navigation at night as you enjoy your visit to earth in your avatar body. :)

Did Bedouins traveling in the vast deserts use the astrolabe to navigate in a similar way to sailors out in open ocean?

yes they used the positions of the luminaries and fixed position of polaris.

In the old days, they used the Julian calendar, which was inaccurate. 1st of November for example this year will drift over time, so results will change dramatically over time, to the point where we had a substantial difference when switching to the Gregorian calendar...did the drift in observation lead to the creation and adoption of the Gregorian calendar?

First of all you must know the date to put the sun and then to find what time is it.becose the sun change position in the year.so if you dont know the date this tool is useless.ofcourse if you count the time sunrise and sunset you can find what day it is but you need a clock or an other count system .if the astrolabe can do this job then it works.becose i do now a senario.a medieval ship go inside the water.a sailor is saved and he is now to a island with a astrolabe.he dont remember what day it is.how he can find the day to line the astrolabe and find time position and to put the sun ofcourse to the right position.i tell again if the astrolabe do this work thats ok.or else this tool is not 100% finised.need more work.of someone know this tool becose i know how this astrolabe works thanks to many videos,just tell me how to find date.thanks and sorry becose i dont speak very good english.

@eddiegoldstein288 4 жыл бұрын

Hi. I'm not an expert on this, but will give it a good guess. For the most part, the user DID know the approximate date and so could set the position of the Sun. This is not hard to imagine since they would certainly know if it were winter or summer, and most likely what astrological sign the Sun was in. That is probably close enough. There are other ways that the user could figure out the approximate position of the Sun. One would be to see (using a compass) where the Sun rose or set. That would match up to where the sun-mark would cross the horizon line on the astrolabe. One could also look at which constellation set immediately after the Sun set to see where in the zodiac the Sun was. Again, these are just ideas of how a lost traveler might use an astrolabe, and some ingenuity, to figure things out.

@@eddiegoldstein62 Hi eddie. Thanks for replying to my question about is the earth is stationary. I can’t find your answer here. Did they blocked it? It seems that before newton, Copernicus, etc. the models they have were that the sun, moon and stars were the one moving instead after that era then we moved to a heliocentric model.

Why is the horizon in the computer screen concave upward? When I look to the horizon it seems straight. I KNOW EARTH IS NOT FLAT! But if I go very high up (60,000 ft or up), I can see the curvature of the earth, and it seems concave downward (not upward).

@eddiegoldstein288 5 жыл бұрын

That is just a function of the computer software. The astrolabe is a "projection" of the night sky, which is different from the shape of the actual night sky. In the same way that a map of the Earth is a projection of the seas and continents, but not the same as a globe of the earth. I set my computer "distortion" to match the "distortion" on the Astrolabe. Neither one shows the actual shape of the sky, but is simply a calculator for the sky.

The rete is the part with the stars. The alidade is the sighting tool on the back, and the rule (with declinations) is the one on the front (frequently only a radius, not a diameter-spanning label).

@eddiegoldstein288 5 жыл бұрын

Hi Tyrel, Although I'm not an expert on astrolabes, I think that the multiple plates refer to different latitudes. So, look up the latitude of your location, then choose the plate that comes closest to that latitude.
