What caught the most attention of the ancients in physics

Mechanics is close to their lives.

Electricity, hydraulic. Well, make a generator, and the steam engine will be very eye-catching.

The rails are all sleepers, and turning stones into gold is similar to turning war into jade silk.

Use the principle of leverage.

The pyramids were found in Egypt and the Americas, including Upper Egypt, Middle Egypt and Lower Egypt in ancient Egypt, and in present-day Sudan and Egypt. In the lower reaches of the Nile, there are about 80 pyramid remains. The largest of them is the Pyramid of Khufu, which is 230 meters high and has a base length of 2.3 million stones, covering an area of 52,000 square meters.

There is no adhesion between the stones, and it is formed by the overlapping and occlusion of the stones. In front of the pyramid of King Havera, there is also a sphinx, a symbol of the king's power and dignity. The Egyptian pyramids are the tombs of the emperors (pharaohs) of ancient Egypt. One of the Seven Wonders of the World.

Do you really think that the pyramid was made by man, but no, it is a product of prehistoric civilization, and with the theoretical principles of physics, you let modern people make one. It is a mystery where a few tons of boulders came from in such a large desert, and how those classic astronomical data were used in a tightly fitting structure, since now, on that occasion, human beings cannot make the same pyramid.

According to the latest research, boulders are mainly transported using buoyancy, including to high altitudes.

In ancient times, people mainly used: levers, pulleys, axles, etc., which are collectively known as simple machinery.

How do I know without context.

Transporting stones: sliding friction becomes rolling friction to reduce resistance.

Hoisting stones: the principle of levers.

The stability of the pyramid (although the pyramid is not a pyramid).

The jury is still out on this. However, it is certainly inseparable from the knowledge of levers, pulleys, buoyancy, etc.

No scientist knows about it at the moment, but it should be mechanical knowledge anyway.
