What is a handicap in golf?

This refers to the number of strokes that a player can hit the ball in excess of the standard number (on normal fields 72) in order to equalize the performance of the fields. Of the two players, the strongest is the one who has the largest difference between his handicap and the number of strokes, naturally, the number of strokes must be less than the handicap.

Author: Mendeleev V.A.

 Random interesting fact from the Great Encyclopedia:

By what chance was Gregor Mendel deservedly recognized as the founder of the theory of heredity?

In the middle of the 1822th century, the Austrian monk and amateur botanist Gregor Mendel (1884-XNUMX) conducted experiments on crossing (through artificial pollination) plants of the same species (at first it was peas, later - beans) with different characteristics.

Mendel was interested in how, after crossing, such traits as the color of peas (green and yellow), their appearance (smooth and wrinkled), and the length of the plant stem (long and short) are transmitted to subsequent generations.

Within 8 years, Mendel made 355 experiments and received about 13 thousand mutant plants, carefully recording the results of observations, which allowed him to draw conclusions that we still call Mendel's laws. In 1863, he completed the experiments, carefully described their results, and sent a copy to the then highly respected German botanist Carl Wilhelm von Nägel.

The professor considered the conclusions of an unknown amateur, moreover, obtained on the basis of a simple count of plants, not worthy of attention and gave them a negative review. In 1866, Mendel published the results of his research in one of the provincial Austrian journals, but this publication did not attract the attention of his contemporaries either. The double failure discouraged Mendel, and he returned to his monastic duties, abandoning his studies.

The name of Mendel and his achievements would probably have remained unknown to posterity if one of the most amazing cases in the history of science had not occurred three decades later. In the same year, at least three people - the Dutchman Hugo de Vries, the German Carl Erich Correns, and the Austrian Erich von Tschermak - independently arrived at the same conclusions as Mendel.

Not being familiar with each other or with the works of Mendel, all three prepared materials for publication in 1900; all three, while working with literature on this topic, to their great surprise, came across Mendel's article; all three published their materials in the same 1900 year. And all three referred to the publication of Mendel, thereby giving him the palm and relegating their work to the rank of only confirming the discovery made earlier.

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 ... >>

The threat of space debris to the Earth's magnetic field 01.05.2024

More and more often we hear about an increase in the amount of space debris surrounding our planet. However, it is not only active satellites and spacecraft that contribute to this problem, but also debris from old missions. The growing number of satellites launched by companies like SpaceX creates not only opportunities for the development of the Internet, but also serious threats to space security. Experts are now turning their attention to the potential implications for the Earth's magnetic field. Dr. Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics emphasizes that companies are rapidly deploying satellite constellations, and the number of satellites could grow to 100 in the next decade. The rapid development of these cosmic armadas of satellites can lead to contamination of the Earth's plasma environment with dangerous debris and a threat to the stability of the magnetosphere. Metal debris from used rockets can disrupt the ionosphere and magnetosphere. Both of these systems play a key role in protecting the atmosphere and maintaining ... >>

Solidification of bulk substances 30.04.2024

There are quite a few mysteries in the world of science, and one of them is the strange behavior of bulk materials. They may behave like a solid but suddenly turn into a flowing liquid. This phenomenon has attracted the attention of many researchers, and we may finally be getting closer to solving this mystery. Imagine sand in an hourglass. It usually flows freely, but in some cases its particles begin to get stuck, turning from a liquid to a solid. This transition has important implications for many areas, from drug production to construction. Researchers from the USA have attempted to describe this phenomenon and come closer to understanding it. In the study, the scientists conducted simulations in the laboratory using data from bags of polystyrene beads. They found that the vibrations within these sets had specific frequencies, meaning that only certain types of vibrations could travel through the material. Received ... >>

Prosthetic hand sense of touch 22.02.2015

The American Defense Advanced Projects Agency (DARPA) intends to give an amputee the ability to feel objects and provide intuitive control over the prosthesis.

Many amputees, despite the most advanced prostheses, have a hard time coordinating their movements due to the lack of feedback. The touch interface system HAPTIX (Hand Proprioception and Touch Interfaces), developed with the support of the US Department of Defense, should solve these problems.

The functioning of the innovative prosthesis will be based on the technology of neural interfaces: its essence is to measure the motor signals transmitted through the peripheral nerves to the muscles, which provide tactile sensations and feedback.

Electronic devices implanted in the muscles, connected to the appropriate sensors on the prosthesis, stimulate the peripheral nerves and transmit information about the touch of an object to the brain, which transmits a signal to the muscles to perform the desired action. The devices receive the signal, decode it and transmit it to the prosthesis, which performs the required manipulations.
