Exodarion Average man of the past are mostly common folk that have limited literacy and science access. A bit of a stretch about your claim in that aspect. The ancient man you claim are the known outliers above the mean. The ability to move such heavy blocks are planned by few individuals then comes the management of laborers who have the cumulative force necessary.

MotherEric With global positioning as its successor, non-electronic navigation devices has diminished use but still useful. Requires training to use effectively, however, and may not be able to fully teach this skill to everyone, just a designated few while others use any technology that requires lower investment to gain a skill leading to the same goal. It's not just the secant, but also the physical map and measurement devices, all subject to risk of human error on an individual level. If there is any error in the step, the whole result gets flubbed that may not be caught in time.

I have just discovered these things and yes, they are amazing. The clever geometry behind them relies on something called stereographic projection, and the reason that is so effective is that it maps circles onto circles, and the heavenly sphere onto a plane. This means that the azimuths and altitude circles can all be drawn on the astrolabe as other circles, rather than anything more complicated like ellipses, which the technology of 200BC would have struggled with.

Just a note not to confuse people, constellations and signs are a different thing. Signs are 30º portions of the ecliptic and constellations are groups of stars, and those have never been the same. The precession moves the 0º Aries, the start of the zodiac, backwards at a rate of about 1º every 72 years in relation to the stars.

Why hide the truth? It's important to acknowledge that the Muslims in the Middle Ages were pioneers in the field of science and innovation. While Europe was still in the Dark Ages, Muslim scientists were advancing knowledge in a variety of fields. For example, the astrolabe, a complex instrument used to measure the positions of celestial objects, was first invented by the ancient Greeks, but it was the Muslims who improved upon it and used it extensively for navigation and astronomy. During this era, Muslims built sophisticated observatories, such as the famous observatory at Maragheh in Persia, which was one of the largest and most advanced observatories of its time. They also made significant contributions to mathematics, including the development of algebra and the use of Arabic numerals. It was through the work of Muslim scholars that the ancient Greek texts were translated into Arabic, preserved, and later transmitted to Europe during the Renaissance. It's also important to note that Muslim women were not excluded from education during this era. Many women, such as Mariam al-Astrulabiya, made significant contributions to science and technology. Mariam was a skilled astronomer and instrument maker who designed and built astrolabes, and her work was widely recognized throughout the Muslim world. Therefore, let's recognize the contributions of the Muslims in the Middle Ages and acknowledge their significant role in advancing science and technology.
