Who created the submarine?

The desire to move under water has arisen in man for a very long time. But the first documentary evidence of a ship actually designed for such a movement dates back to 1578. British mathematician William Bourne included in a book published this year a drawing of a boat that was closed on all sides and could dive and row underwater. She was wooden, covered with waterproof skin, and had to sink by reducing her volume by squeezing the sides with hand grips.

Bourne never built his boat. A similar boat built by another inventor was sunk in 1605. But usually the priority in the construction of the first submarine is given to the Danish inventor Cornelius van Drebbel, who in 1620 repeatedly tested his offspring on the River Thames at a depth of 3 to 4 meters.

Van Drebbel's boat had another outer hull, which consisted of a wooden frame covered with greased leather. She moved with the help of oars that passed through the sides and were hermetically fixed with tightly fitting leather flaps.

The interest in building submarines was so great that by 1727 at least 14 different designs had been patented in England alone. The submarine was first used as a military weapon in naval warfare during the American Revolution. A certain David Bushnell invented an ultra-small one-man submarine, which was nicknamed "turtle".

"Turtle" tried to sink a British warship in the port of New York by attaching a powder charge to its bottom. This attempt failed: the charge did not work, but still after that, not wanting to take risks, the ship hurried to go to the open sea.

Random interesting fact from the Great Encyclopedia:

What animals are able to remove foreign objects from their body through the bladder?

Frogs are able to remove foreign objects from their bodies through their bladders. This discovery was made by Australian scientists by accident. During the experiments, they implanted transmitters into the bodies of frogs. A few weeks later, the frogs were caught and found that most of the devices had moved into the bladders, and some came out with the urine. It turned out that when a foreign body appears, soft tissues begin to grow to it, which gradually envelop the object and draw it into the bladder.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

robot plant 18.11.2019

Engineers from the Massachusetts Institute of Technology (MIT, USA) have developed a robot that can lengthen, "building up" new links. At the same time, its entire chain is flexible enough to bend and turn, and at the same time rigid to withstand heavy loads. The robot can change its length and shape by removing links or adding new ones.

The scientists developed the design of the robot, inspired by the way plants grow: nutrients rise up to the tip of the plant, where it then gradually forms a dense structure, such as a stem or side shoots.

The robot operates in much the same way: it consists of a drive box - a "growth point" - that pulls a loose chain of links ("nutrients") into the box. The gears in the box then block the chain links and bring the chain out again - but in a locked position. From this chain, it seems that a strong stem is obtained, which holds a heavy "flower" for sure - a gearbox.

The researchers presented the "growing robot" at the IEEE International Conference on Intelligent Robots and Systems (IROS) in Macau, China. They suggest that the robot's drive box could be fitted with grippers, cameras, and other sensors, allowing it to slip, for example, through an aircraft's propulsion system and tighten a loose propeller, or reach a shelf and pick up product without disturbing the organization of the surrounding inventory.
