Many people honored him as the only “all-powerful scientist” in human history. In the words of the ancients, scientists, painters, this idea is “Fantastic talent”. But there are also many unsolved mysteries about this celebrity’s identity. Some people even say that Leonardo da Vinci is an alien, so he has such a transcendent thought. For example, the question about the heart that took humanity 500 years to answer. Is Da Vinci really an alien? What is the puzzle about the heart that he left that people 500 years later find the answer to? Portrait of Leonardo Da Vinci. Leonardo da Vinci’s life is full of mysteries, he was born in the 15th century in a small village. Until his death, he had no official surname. The real reason was because he was an illegitimate son. And the person who started this heartbreaking story was his father. The father was originally from a prestigious family but fell in love with a mediocre peasant woman, Leonardo da Vinci’s mother. No one knows how they are together, which makes his background even more difficult to answer. There are many mysteries about his identity. The first years of his life were quite peaceful. Over 10 years old, he went to a cave and stayed for a few months. Then, from an unknown person, he became a shining gem in the evolutionary history of human civilization. He left posterity more than 15,000 manuscripts. Among these manuscripts, there are many inventions appearing in modern science and technology. The more science develops, the more mysteries about Leonardo da Vinci begin to be opened. Hundreds of years ago, this miraculous man painted a perfect picture of the structure of the human skeleton and internal organs. In addition, he also drew the shape of the fetus. It is worth mentioning that his painting of the structure of the human body left a puzzle about the heart that took scientists 500 years to figure out! In the hand-drawn picture, in the heart there is a very small muscle fiber located on the inner wall of the ventricle. To this day, many people refer to it as “Trabeculae myocardium”. For a long time, scientists didn’t know about it and didn’t know what it did. It was not until 500 years later that the “trabeculae heart muscle” left by Leonardo da Vinci had the answer. Scientists confirm that this part has a close relationship, directly affecting human health. The sketch left by Da Vinci. In addition to hinting at the “heart muscle Trabeculae”, from the late 15th century, Leonardo da Vinci designed a very robot-like motor. In his sketches, helicopters also appeared. In 1490, he also manually sketched an automatic transmission, which until now has not been widely used in many fields. When humanity felt that Copernicus had bravely stated the heliocentric theory (the sun is the center), Leonardo da Vinci had earlier mentioned the concept of the universe. He thought that the earth was just a planet revolving around the sun, and the light from the moon was just a reflection from the sun. On the other hand, with the conservative thought of that time, he once mentioned the use of solar energy. This timeless thinking makes many people unable to understand, even thinking that Leonardo da Vinci is crazy! Up to now, it is hypothesized that, if 500 years ago his ideas were successfully implemented, it is likely that the current science and technology will develop beyond 500 years. Because of such strange things, many people doubt the identity of Leonardo da Vinci, thinking that he is not an ordinary person but an alien. Or maybe he had traveled through time to a future world. Otherwise, it is really difficult to explain why he has such strange thoughts. The more people think about his teenage years, the more people believe that this genius is not an ordinary person at all. As a child he mysteriously lived in a cave for a while, only a few months later he seemed to be reborn as a new person. These are the words that he himself said to the people. Until now, in his manuscripts there are still many contents that people cannot understand. It may be because the time is not yet ripe, or it may be that the human mind at present cannot keep up with his thought. Therefore, there are still many mysteries that must be solved by the next generation. In the world famous painting “Mona Lisa”, that mysterious smile has also attracted all mankind to find the solution. The famous painting “The Last Supper”. In short, people often say that Leonardo da Vinci is an alien because of the timeless thought he brings. Many years later, with the development of science and technology and the progress of civilization, his thought finally became a reality. Until today, people have been admiring the outstanding intelligence of Leonardo da Vinci. Perhaps geniuses and ordinary people live in two different worlds, and geniuses also have to endure more difficulties and misunderstandings!

The move comes after Chinese Vice Premier Liu He said last week in a statement that it was necessary to “suppress the behavior of Bitcoin mining and trading” to prevent “the transmission of personal risk to social spheres”. Those comments are seen as Beijing’s intention to further block Bitcoin trading and other crypto-related activities. Inner Mongolia’s latest draft proposals are aimed at telecommunications and internet companies involved in cryptocurrency mining. The Inner Mongolia Development and Reform Commission said such companies could have their business licenses revoked if they are found to be involved in Bitcoin mining. In addition, cloud computing or data centers may have their government incentives revoked. In addition, there are severe penalties for individuals involved in money laundering through cryptocurrencies. Inner Mongolia’s tough stance on crypto mining began in March after it announced plans to ban new crypto mining projects and shut down existing operations to cut consumption. energy. China’s Northern Region failed to meet Beijing’s energy use targets in 2019 and subsequently set out a plan to reduce power consumption. In the case of Bitcoin, miners purposefully use computers to solve complex mathematical puzzles that allow a Bitcoin transaction to take place efficiently. These miners are rewarded with Bitcoins. But because the computer has a large capacity, it consumes a lot of energy. According to the Cambridge Bitcoin Electricity Consumption Index, Bitcoin mining consumes around 112.57 terrawatt-hours (TWh) per year, more than the consumption of countries like the Philippines and Chile. China accounts for about 65% of the world’s Bitcoin mining. Of that, Inner Mongolia accounts for about 8% globally due to cheap energy prices, a larger share of Bitcoin mining in the United States. China’s tough stance towards cryptocurrencies is not new. China previously shut down local cryptocurrency exchanges in 2017 and that same year also banned initial coin offerings (ICOs). But Bitcoin trading continues to operate in China even though exchanges have moved overseas. Inner Mongolia’s scrutiny of Bitcoin mining activity in particular comes as China tries to continue the move. Chinese President Xi Jinping said last year that China has set a goal of becoming carbon neutral by 2060. But according to a study published in Nature Communications in April 2021, Bitcoin mining could “undermine emissions reduction efforts” going on in the country. The energy consumption of Bitcoin mining operations came back into focus in early May after Tesla CEO Elon Musk said the electric carmaker would stop accepting the digital currency for the reason due to environmental concerns. On Monday (May 24), Musk said in a tweet that he has met Bitcoin miners in North America and that they are “committed to announcing current and planned uses of renewables.”

He added that the Abel Prize (considered the Nobel Prize for Mathematics) in 2021 was awarded to a pioneer in the field Zero Knowledge Proof – Scientist László Lovász (Mathematical Institute Alfréd Rényi and University of Eötvös Loránd in Budapest, Hungary), and Avi Wigderson (Institute for Advanced Study in Princeton, USA). The puzzle is as follows: Isla works in an office with 100 employees. One day, she discovered that her favorite paperclip was stolen by someone else. She identifies the suspicious object. Annabel, her colleague, said she was also suspicious of a person. Isla wants to know if she and Annabel are suspicious of the same person, but the two don’t want the other to know who they are doubting, in case they suspect different subjects. Isla thinks over and over how she and Annabel can check if they suspect the same person without revealing the information they find suspicious to the other party. The question is whether Isla and Annabel can find a way to reconcile their thoughts without letting the other know who they are doubting? This method should ensure that, after comparison, Isla knows whether she and Annabel are suspicious of the same person. Second, they need to make sure the other person doesn’t know they are distrusting. This verification is part of the protocol Zero-knowledge . At first glance, Alex Bellos judged that this was a puzzle without a solution. For example, Isla cannot say “The person I suspect was late for work on Monday” because it revealed some information about the other person. He also came up with a third party two-man solution, Dan, a good friend they trust a lot. Then, Isla and Annabel numbered the office staff from 1 to 100. Next, they write the number to replace the name of the suspect on a piece of paper and give it to Dan. If Dan confirms the two numbers are the same, they suspect the same person and vice versa. However, this solution is not perfect as no one can guarantee Dan from disclosing his number to the other person. Everything depends on the level of trustworthiness of the third party. Therefore, it cannot guarantee the non-disclosure of information as the quiz requires. Nearly 200 people participated in discussing Alex Bellos’s riddle and proposing measures to verify that Isla and Annabel were suspicious of the same person. Then, the author Alex Bellos together gave 3 relatively suitable methods. Can you take any measures to ensure the request of the assignment or not, ie Isla and Annabel know if they are suspicious of the same person and do not disclose information about the suspect to the other person?

“This work makes it possible for us to understand part of the study,” said Benjamin Hess, a graduate student in the Department of Earth Sciences and Planetary Science at Yale University and the first author of the study. form life on Earth, and possibly extend to study of planets – life could be forming on those planets in a similar way “. The origin of life also commonly known as the process of life generation (abiogenesis) is a term for the different theories about the formation and development of life on Earth. Of these theories, the most popular up to now are the scientific theories that say: this is the natural process by which life arises from non-living matter, from inorganic substances into single organic compounds. simplified, then evolved into today’s world. As we all know, phosphorus is an essential component of life on Earth. Even looking for extraterrestrial life in space, scientists will look for signs of phosphorus. However, billions of years ago, phosphorus was trapped in insoluble minerals and was difficult to escape and exert its effects. Therefore. This issue has been of interest to scientists for many years, who want to know how phosphorus is converted into an easier to use form, thereby promoting life-generating processes. Researchers suggest that the phosphorus that helps create life on Earth may come from schreibersite, a rare but very common mineral in meteorites. When lightning strikes soil or sand (derived from meteorites) on the ground, it can instantly melt and then solidify to form natural glass – fulgurite (also known as clayey rock. ). These meteors can be submerged, meaning that in the presence of water, the phosphorus in this mineral can be dissolved outward and potentially become part of a chemical reaction. Although the details of life’s formation on Earth are still unknown, the popular scientific hypothesis is that the transition from non-living entities to living entities is not an event. single, which is an increasingly complex process involving molecular self-replication, self-assembly, autogenesis and the appearance of cell membranes. Although the occurrence of the origin of life is not controversial among scientists, there is no single accepted model for the origin of life. Initially many scientists agreed with this idea, but through intensive research and statistics, they found that from 3.5 to 4.5 billion years before life on Earth was born. The number of meteors on our planet is not enough to be life-boosting factors. In the new study, Hess et al. Proposed that phosphorus on Earth could come from lightning strikes. They believe that this is more likely than that of elemental phosphorus coming from meteorites, because compared to asteroid collisions, the number of lightning strikes Earth each year is relatively stable. “This makes lightning an important way to study the origin of life,” Hess said. The team also used computer modeling to estimate how many lightning strikes occurred on Earth during the critical period in the beginning of life. They found that there could be between 1 billion and 5 billion lightning strikes the Earth each year, and 100 thousand to 1 billion of them falling on the Earth’s surface. Earth remains the only place in the universe known to life, and fossil evidence from Earth facilitates most studies of the origin of life. The age of the Earth is about 4.54 billion years, the earliest irrefutable evidence of life on Earth dates back at least 3.5 billion years ago, and possibly as early as the Ancient Pre-Tai era ( 3.6 to 4.0 billion years ago), after the geological crust began to harden after the molten Hadean Eon. In May 2017, scientists found possible evidence of early terrestrial life in the 3.48 billion year old geyserite and other related mineral deposits (often found around water springs). hot and geysers) discovered in Pilbara Craton, Western Australia. According to the study’s estimates, the number of lightning strikes on Earth could reach 10 ^ 17 to 10 ^ 18 in a billion years. Researchers suggest that under the impact of too many lightning strikes, after 1 billion years, ores formed by lightning strike the ground can release phosphorus that can participate in chemical reactions in the presence of water. In other words, it was lightning in this period that produced enough phosphorus to explain the existence of phosphorus at the origin of life on Earth.
