Can you use the angle to the polar star to determine the current date? Or at least narrow it down to 2 possible dates?

You are a HORRIBLE INNEPT teacher, you don't make any sense whatsoever.

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

Good video, the black piece that represents the horizon that he turns is called a rule

This actually made sense. Thank you.

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?

Excellent video.

Thanks Eddie,a very good account of the astrolabe .

Thanks thanks and thanks again 🙏🙏🙏🌹🌹🌹

Sir we made astrolobe for our project but one thing we didn't understand that is the relation between zodiac constellation and outer most degree scale for example why Libra is on 0 degree please answer if you know...

HELLO, WERE CAN I GET ONE OF THOSE BIG ASTROLABES ?

Amazing clear explanation

Proving the flat earth thank you. Star would all be moving separately especially after thousands of years. Those stars would have moved.

It was beautiful. MJ would be very happy. Thank you very mach.

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?

Who made the first astrolabe? Where and when?

glorious

Hey Eddie ! EARTH IS FLAT ! my frend !

Thank you for a nice explaination

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.

Until now is the best explain about astrolabe.exellent work sir becose i can understand how this tool work.hello from greece.

Great Video!!! Rreally helpful! Although, you should have put Rigel and Betelgeuse in the description, because all I heard was baitul juice... (I wasn't familiar with English names for the stars) .

Hi Mr Eddie I remember you doing this trick at the singapore sci buskers festival

Where could I buy an astrolabe? I have been looking to buy a working one with Roman letter script so I could try to actually read and use it.

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).

Thank you so much. I give my children Arabic lessons once a week and we end with something from Arabic culture. This week's lesson was about the astrolabe and we watched the explanation from the British Museum. Yours is more in depth and superior.

Thanks so much, this is the clearest explanation I've found so far, even compared to the one from BBC. Bravo!

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).

Where did you get such a large astrolabe from?

Like a lot of astrolabes, mine has multiple plates for the background sky. How do I know which one I am suppose to use from my position on the planet?

very clear explanation! Thanks for sharing :)

Great job Eddie!
