What were ships made of in ancient Egypt?

The first boats among the Egyptians appeared in 5000-3500 BC. These vessels were made of papyrus and were intended to sail on the Nile, the largest waterway in the ancient world. Papyrus stalks were gathered into strong bundles and woven into a thick curved mat, the ends of which were raised. The rigidity and shape of this design was given with the help of a special strong cable, also made of papyrus.

But Egyptian shipbuilders did not limit themselves to papyrus vessels. In the period from 3200 to 2240 BC - the time of the great dynasties of the pharaohs - the Egyptians built wooden ships. Outwardly, they resembled their papyrus counterparts. The same profile with raised bow and stern, the same flat bottom.

Ancient Egyptian boats were the first type-setting ships. Their body consisted of an inner frame (set) and plank sheathing.

 Random interesting fact from the Great Encyclopedia:

What was a Cro-Magnon?

There was a time in the thousand-year course of human development when man lived in caves. Probably the most interesting cave dwellers were the Cro-Magnons. They lived in Europe at the end of the Ice Age. They are so named only because the remains of these cave dwellers were found in the town of Cro-Magnon in southern France.

Also interesting is the fact that experts who studied the remains, the skeletons of these cave dwellers, found that they were quite civilized and intelligent people. If they lived today, they could become scientists, statesmen or businessmen. These people lived in turbulent times, surrounded by wild animals and other dangers. But despite this, they found time to make beautiful drawings on the walls of the caves.

The drawings have come down to our time, are well preserved and delight us with their beauty and skillful technique. These people had a well-developed social life. They lived in families. But since they began to hunt in groups, they had to unite in tribes. They believed in the afterlife: that the dead could be resurrected and reborn in the other world.

Gradually they created more advanced stone tools and new weapons. They learned how to carve a spear and a harpoon from horn and bone. They also invented arrows for guns. Women learned how to process skins and sew clothes from them with bone needles. As we can see, these people had intelligence and reached a high stage of development.

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Primium Seneca keyboard 05.05.2024

Keyboards are an integral part of our daily computer work. However, one of the main problems that users face is noise, especially in the case of premium models. But with the new Seneca keyboard from Norbauer & Co, that may change. Seneca is not just a keyboard, it is the result of five years of development work to create the ideal device. Every aspect of this keyboard, from acoustic properties to mechanical characteristics, has been carefully considered and balanced. One of the key features of Seneca is its silent stabilizers, which solve the noise problem common to many keyboards. In addition, the keyboard supports various key widths, making it convenient for any user. Although Seneca is not yet available for purchase, it is scheduled for release in late summer. Norbauer & Co's Seneca represents new standards in keyboard design. Her ... >>

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

Painkillers reduce empathy 01.06.2016

One of the most popular pain relievers is acetaminophen, commercially known as Tylenol. Acetaminophen is an ingredient in several hundred medications. In the United States, 52 million people take it in one form or another every week. Researchers at Ohio State University have found that acetaminophen has a rather odd and not-so-good side effect.

The experiment involved 80 healthy young people: half of them were asked to take acetaminophen (the maximum single dose that is usually prescribed), while the other half were given a placebo. An hour later, both of them read several short stories that told about people suffering from physical pain or from mental wounds. Readers were required to indicate how much they felt the characters in the stories were suffering. And it turned out that after the painkiller, the severity of feelings for others decreased - that is, for those who took acetaminophen, it seemed that the heroes of sad stories did not suffer so much.

In the second experiment with another group of students, they did the following: they were also given an analgesic and a placebo, and then they were forced to listen to several very strong sound signals, unpleasant to the ear, in a row. Then they had to say how unpleasant the sound was - for themselves and for someone else who would also hear it.

The researchers concluded that after acetaminophen, the acuity of sensations decreased: those who drank painkillers did not suffer as much from loud noises compared to those who did not drink it. And the same thing happened with the experience of other people's sensations: after the analgesic, it seemed that the other person was not so unpleasant either.
