What animals were the inhabitants of the Augean stables?

In one of his exploits, Hercules cleared the stables of King Avgii, from which no one had removed manure for thirty years, breaking the wall around them and directing the channels of two rivers there. In this classic story, a terminological inaccuracy is less known: the main inhabitants of the "stables" were not horses, but several thousand bulls, so it would be more appropriate to call them barns. However, it was the "Augean stables" that became a catch phrase, meaning an extreme degree of disorder.

Who were the first Europeans in Australia?

It is believed that the northern coast of Australia was first seen by the Dutch navigator Billem Janszon at the beginning of the 1770th century. However, there is evidence that he was still ahead of the Portuguese sailors. In any case, already in the XNUMXth century, the Dutch visited the northern, western and southern shores of the unknown continent. In XNUMX, the English navigator James Cook discovered the east coast of Australia. Cook declared that the land he had discovered belonged to Great Britain and named it New South Wales.

By this time, people were already living on the continent. Europeans called them natives. The natives had dark skin, thick lips and a wide nose, like the Negroes, and long wavy hair, like the Europeans.
By the XNUMXth century, Great Britain had lost its colonies in North America and needed new lands. In addition, English prisons were overflowing with convicts who had nowhere to exile: after all, for more than a hundred years they were sent to North America.

The first ship with the exiles left England for the distant mainland in May 1787. In January 1788, 850 exiles and about 200 soldiers and officers landed on the east coast of Australia. Among the exiles were both dangerous criminals and those convicted of minor offenses.

The first convict settlement was called Sydney. The regime there was very cruel.

In 1793, the first free settlers arrived in Australia. But there were few of them, and the new lands were developed mainly by convicts. In the 50s of the 10th century, gold was found in this distant colony. During the 1,2 years of the "gold rush" the number of British in Australia has almost tripled. Already XNUMX million people lived there.

From 1868, criminals were no longer exiled to Australia.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

Ultra Low Gravity Measurement 19.03.2021

Precise experiments made it possible to measure the attraction between objects with a mass of only 0,09 grams and showed that Newton's law also applies at this level.

It has been known since the time of Isaac Newton that the force of gravitational attraction between a pair of objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. The general theory of relativity, which appeared at the beginning of the XNUMXth century, which considers gravity as geometric deformations of space-time, more accurately describes the behavior of massive topics on astronomical scales. But how gravity behaves on the opposite side of the scale, at the level of elementary particles, is unknown.

Even tests of Newtonian formulas are carried out, as a rule, with objects with a mass of the order of kilograms and grams: their gravity is so small that it is extremely difficult to measure it. Recently, however, the team of Tobias Westphal of the Austrian Academy of Sciences managed to do this work for golden spheres weighing only 90 milligrams, registering a record low gravitational force.

The experiments are based on a scheme invented by Henry Cavendish, who measured the gravitational interactions between objects in his laboratory for the first time in this way. To do this, he fixed the test mass (lead ball) at the end of a wooden beam suspended by a thread, and balanced it with a second ball of the same kind. A second, more massive ball slowly approached the test load, the attraction of which caused the rocker to rotate slightly. By registering the twisting of the thread, it was possible to accurately estimate the amount of rotation and calculate the force of attraction between the masses.

Tobias Westphal and his colleagues conducted a similar experiment, in which gold spheres weighing only 90 milligrams, mounted on a miniature glass yoke and suspended from a very thin silicon thread, served as test weights. The deflection of the rocker arm was recorded by turning the mirror mounted on it, which was illuminated by a laser beam. And, of course, working at this level of accuracy, scientists had to perform experiments in deep vacuum and carefully shield electromagnetic fields using a Faraday cage.

Careful measurements have shown that Newton's formula continues to work on the scale of milligram masses. Calculating the gravitational constant (G) based on their measurements, scientists have shown that it is only nine percent different from the standard accepted value. But the main thing is that the authors have demonstrated that such measurements are possible in principle and allow registering ultra-small gravitational forces. Perhaps someday they will help to understand their work at the level of elementary particles.
