How can one relate the ancient egyptian cubit geometrically to the speed of light?<|im_end|>
<|im_start|>assistant
There is no direct geometric relationship between the ancient Egyptian cubit and the speed of light, as the cubit was a unit of linear measurement used for practical purposes such as construction and trade, while the speed of light is a physical constant related to the propagation of electromagnetic radiation in a vacuum.

However, some researchers have attempted to find connections between the cubit and the speed of light through various numerical and geometrical coincidences. For example, some have pointed out that the length of the royal cubit (which was the standard cubit used for most official measurements) is roughly equivalent to the length of a certain number of wavelengths of light in a vacuum, or that certain geometric relationships involving the cubit and other ancient Egyptian units of measurement have numerical values that are related to the speed of light.

However, it is important to note that these coincidences are speculative and not based on any historical evidence or scientific principles. There is no evidence to suggest that the ancient Egyptians had any knowledge of the speed of light or that they used the cubit in any way related to this physical constant. Therefore, any attempt to relate the cubit to the speed of light should be considered purely speculative and not based on any scientific or historical evidence.<|im_end|>

Why did ancient egyptians build in cubes then?<|im_end|>
<|im_start|>assistant
It's not entirely accurate to say that the ancient Egyptians built in cubes. While they did use geometric shapes in their architecture, such as squares, rectangles, and triangles, they did not generally use cubes as a building block.

The primary building materials used in ancient Egyptian construction were mud bricks, limestone, sandstone, and granite. These materials were shaped and fitted together in a variety of ways to create structures such as pyramids, temples, tombs, and houses. The shapes used were dictated by practical considerations such as the available materials, the needs of the structure, and the skills of the builders.

It is worth noting that the ancient Egyptians did have a sophisticated understanding of geometry and mathematics, and used these concepts in various ways in their art and architecture. For example, they used the principle of the golden ratio to create aesthetically pleasing proportions in their art and architecture, and used complex geometric designs in their jewelry and pottery. However, the use of cubes as a primary building block was not a feature of their construction techniques.<|im_end|>
