Astronomical "precession";

The precession of vernal equinox has rigorous and repetitive mathematical characteristics, which can be accurately analyzed and predicted. However, without sophisticated instruments, it is difficult for us to observe it, let alone measure it accurately. When did the ancients first calculate precession? The answer to this question is to understand one of the great secrets of human history.

According to historical records, it was the ancient Greek scholar Baccus who discovered the astronomical phenomenon of precession: in the 2nd century BC, he proposed the age difference of 45 or 46 seconds (very close to the figure of 50.274 seconds accepted by modern astronomy. But the error is very small, because the annual variation is 50.274 seconds, which is less than l/60 of l degrees. Therefore, it takes about 72 years for the sun to move L degrees along the ecliptic in vernal equinox, which is equivalent to a person's life.

Because it was difficult to observe this extremely slow change at that time, the age difference proposed by Baccus in the second century BC will be regarded as a "great discovery" by the Encyclopedia Britannica.

A group of key figures hidden in ancient Egyptian mythology;

In the book Death of the Gods in Ancient Egypt, archaeologist Jane Cyrus mentioned that a set of key numbers may be deliberately hidden in the Osiris myth in Egypt. These numbers may be "redundant" in the story, but they can provide us with an eternal calculation method.
