Who graduated from university and wrote 12 books while being blind and deaf and dumb?

American Helen Keller completely lost her hearing and sight in infancy, but thanks to her willpower and the skill of a special teacher, she learned to perceive speech, feeling the vibration of the lips of a speaking person. After that, Helen learned to read Braille in five languages, graduated from high school, and then university. Subsequently, she devoted her life to politics, social work and the protection of the rights of people with disabilities, and also wrote 12 books.

Random interesting fact from the Great Encyclopedia:

What is plankton?

The word "plankton" comes from the Greek word, which means "wandering", "going with the flow". Plankton is a floating living mass made up of billions of tiny living organisms. Some of these organisms, such as tiny green plants, always remain plankton. Others, such as fish, lobsters, make up the plankton while they are in the embryonic stage. Sometimes in the composition of plankton there are large jellyfish or such small creatures that cannot even be seen through a conventional microscope. But all the plankton can stay afloat and live together, drifting with the flow.

The smallest plankton organisms are single-celled plants, microscopic algae. One of the most numerous varieties of such algae is called diatoms, or flint. In two liters of water there can be up to a million of them. The animal life of plankton is quite interesting. One of its species is the pear-shaped copepod (copepod means "copepod"). The copepod swims very fast, making sharp, jerky movements with its tiny paws, as if rowing on oars. The largest copepod is less than 13 mm long.

Young molluscs of various species also make up the plankton. Among them are shrimp, crabs, lobsters and sea ducks (a type of crustacean) living in salt water, as well as lobsters and water fleas - inhabitants of fresh water. The larvae, or developing juveniles, of these mollusks are tiny, microscopic, and at this stage of development cannot move independently, and therefore drift along with other plankton.

Other mollusks, such as snails, mussels, behave in the same way. They are part of the plankton at the first stage of their development. Plankton may include insect eggs and the larvae of many fish. In fresh water, plankton often includes developing insects.

Flying flies, dragonflies, water beetles and many other insects lay their eggs in the water. When the larvae hatch from the nest, they live and feed on plankton plants. This is only part of what makes up plankton. You see how many animals and plants are included in it and how interesting it is to study them.

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. ... >>
