How do possums differ from possums?

Possums and opossums are different mammals, although together they belong to the infraclass marsupials. Technically, it is more correct to call all species of the couscous family that live in Australia, New Guinea and a number of islands of Oceania as possums, and all species of the possum family that live in America as possums. Name confusion arose from the expedition of James Cook, whose biologist described the Australian animal he saw as an animal from the tribe of possums, and continues to this day: the English words possum and opossum are applied with equal success to both American and Australian mammals.

Who Invented Paper?

Take a sheet of paper and try to tear it up and down. You will notice that the paper is more easily torn on one side than the other, and where the paper is torn, hair-thin fibers are visible.

What does it say? First, paper was made by a machine, otherwise it would tear equally in both directions. Second: paper consists of the smallest particles of cellulose, which forms the frame of a tree.

Man invented writing material long before there was paper. The ancient Egyptians, about 4000 years ago, took papyrus stems, peeled off the skin, and straightened it out. Then the strips of papyrus were laid crosswise and pressed so that they stuck together. A dried papyrus sheet was a good material for writing.

But it wasn't paper yet. It was invented in China around the year 105 by a man named Cai Lun. He found a way to make paper from the fibrous inner bark of the mulberry tree.

The Chinese learned to crush the bark in water to separate the fibers, then they poured the mixture onto trays that had long, narrow strips of bamboo at the bottom. When the water drained, the soft sheets were laid out to dry on a flat surface. Bamboo and old rags were used for this purpose. Later, someone figured out how to improve the quality of paper by adding starch to it.

Merchants from China traveled far to the north and west and came to the city of Samarkand. There the Arabs took over their secret and brought it to Spain. From there, the art of making paper spread throughout the world, reached Europe and came to England.

Over time, all sorts of methods were discovered and different machines were created for releasing paper. One of the most important was a machine that allows you to make long and very thin sheets of paper. It was invented in France in 1798.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>
