alt Hacker NewsGalileo's handwritten notes found in ancient astronomy text

It’s unbelievable how that 16th century book looks like it is written in LaTeX. Or plain TeX, probably, given its age XD
That's not "ancient". That word often means thousand(s) of years ago.
Fun facts, the patron of Almagest Abassid Caliph Al-Ma'mun was also the founder of Baitul Hikmah in Baghdad that was aggressively translating important foreign manuscripts due to weight gold equivalence for Greek/Indian/etc manucsripts translation compensation [1],[2].
According to history, the Caliph once back off his plan of conquering Constantinople (that were later achieved by Ottoman Caliph Fatih) due the Roman (Byzantine) offered him an offer he cannot refused, the original copy of Ptolemy Almagest as important part of the truce arrangements. He certainly capable of overcoming and conquering the Constatinople since during his time, Afghanistan was conquered under Islamic rule for hundred of years that modern Russia and USA cannot achieved. The fact that his mother Marajil, was a princess originally from Afghanistan. This is where the popular saying that asserted only Afghanistan people can conquer Afghanistan. Point in case, the most recent Afghanistan conqurer was Mughal Empire, who was originated from Indian sub-continent Afghanistan. During his time, Al-Khwarizmi published his infamous Algebra book namely Kitāb al-Mukhtaṣar fī Ḥisāb al-Jabr wal-Muqābalah (The Concise Book of Calculation by Restoration and Balancing), where we got the word algebra, and from his name Al-Khwarizmi now we have the word "algorithm" [2].
In addition to having translation Baitul Hikmah in Baghdad, Iraq and in other Islamic knowledge center in Toledo Spain (before fall to Spanish Christian and started the European Renaissance), the Islamic civilization also engaged in contributing to science, math, astronomy, etc. Al-Haitham (Alhazen), the founder of optics, and he's also the founder of modern scientific methodology [3].
Having said that, there several Islamic astronomers (Arab/Persian/etc) already proposing against the geocentric idea that most probably that was inspired Galileo. I think he most probably did not come with the original idea of heliocentric model and the Islamic astromoners mosy probably have proposed it before Galileo, but he failed to credit them properly as normally practiced by European scientists at the time.

Not particularly important, but the title adding "handwritten" implies that they had non-handwritten notes too...
What a wild find. Good for the historian.
Galileo Galilei, and yet people still refer to him by his firstname alone. It's painful to read.
It is, as if we refer to Isaac and Albert when speaking about Gravity and Relativity.
I have had the experience of serendipitous discovery when researching relatively recent history. To find Galileo’s handwriting 400 years later, effectively engaging in both agreement and debate with Ptolemy through the latter’s work… even though he specifically was looking for it, it still must have been surreal.
