Carl von Linné -hay Linnaeus - is a great Swedish doctor and botanist. Considered Darwin's most important predecessor, he is best known for his work Systema naturae, a system for classifying plants, animals and minerals. This year round 300 years he was born. Carl Linnaeus was born on May 23, 1707, in a small village called Råshult in southern Sweden. His father, Nils Linnaeus was a pastor. It was his father who instilled in him the love for plants. Legend has it that young Carl had a love for plants and flowers from the womb, because his mother during pregnancy often watched the strange and wonderful flowers in her husband's flower garden. Carl wrote of himself poetically at birth: "Only when spring is at its cutest weather and the crowing of the crow signals the coming of summer" - that is May. In the past, Carl's cradle was made of beautiful flowers with a sweet scent.
Like his elder brother Niel Abel, Sophus Lie (1842-1899) has emerged as a phenomenon in Northern European countries in the context of the scientific background of this region was virtually unknown on the international arena. Throughout his life, he constantly came up with extremely bold ideas. Sophus Lie is one of the big names in mathematical history, one of those visionary. He also created a new subject: Lie group mathematics, which is now developed and rooted in almost all the fields of mathematics and mathematics-physics. Jean Dieudonné, one of the founders of the Bourbaki school, would not have been able to produce any valuable work without Lie's mathematics. Later mathematical and physical works, particularly those of Élie Cartan and Hermann Weyl, were also successful thanks to Lie's mathematical theory. During a period of 30 years of research, Sophus Lie published works about 8,000 pages in handwritten.
How can romantic and romantic sunsets relate to alternating current electric motors? In dreams, anything is possible, especially the dream of a genius inventor like Nikola Tesla. And here, it is important that Tesla's dreams have given mankind the most basic and important inventions of industrial civilization. When members of the Chicago Chamber of Commerce listened to a lecture by famous electrical inventor Nikola Tesla on May 13, 1899, they were stunned to see an artificial lake in the middle of the hall. Everyone was chattering, surely Tesla would do something very interesting with a small canoe floating on the other lake. Suddenly, the boat suddenly moved around the lake and emitted gleaming lights. On shore, Tesla operates a remote control unit, which uses invisible radio waves to transmit commands to the boat. In front of the excited crowd, Tesla invited some people to shout: "Turn left! Glow!". Using its wireless transmitter, Tesla continuously transmits signals to the boat. Even more interesting, Tesla also showed people a special fake battle screen, driving dynamite blasts into the enemy ships. At the time, Tesla was unaware that his "toy" model had become the first prototype of a guided missile - an extremely dangerous weapon.
Just over a year ago, he was one of the great theoretical physicists of our time, who in the 30s of the last century had found nuclear reaction cycles, discovered the Huge energy source of stars. With the merits of calculating and explaining the Lamb shift, he is considered by many to be the father of quantum field theory. His life also has many paradoxes. This skinny man had a sickly but funny smile as the head of the Institute of Theoretical Physics in Los Alamos during the US deployment of the wartime Manhattan program. Had been an important figure in the creation of the first atomic bombs, but after the war, Bethe became a brilliant orator, struggling to oppose nuclear weapons during the negotiation period. in Geneva to go to the east-west peace treaty, disarmament.
With the help of Ms. Felice Frankel, the scientists turned dull images of things like yeast on a plate or the surface of a CD, into impressive images. "She changed the visual face of science," said Dr. George M. Whitesides, a chemist at Harvard University. Art is not a visible concept When called an artist, Felice Frankel often frowned. First of all because the pictures she took were not for sale. After receiving a grant from the Guggenheim Museum in 1995, she began bringing her work to the gallery, but no one was sad to see it. Second, her photographs do not include emotions, ideology or any other message. She said: "My material is the natural phenomena such as the magnetic field, the activity of water molecules, or the growth of bacteria. I don't call it art. Because if it were art, it has to say more about the creator of that work, not just the concepts seen in images. "
Ludwig Edward Boltzmann was born on February 20, 1844 in the Landstrasse district of Vienna, began studying physics at the University of Vienna in 1863 and received his doctorate in 1866. At the age of 25, Boltzmann became a professor of mathematical physics at the University. studied Graz and then returned to Vienna University in 1873. In 1876, Boltzmann married Henriette von Aigentler, a beautiful woman with long hair and blue eyes from Graz. During his 14 happy days in Graz, Boltzmann developed his ideas about the statistical concept of nature.
Perhaps in this world no one is as weird as Bill Stone: Explore the deepest caves in the world to train and prepare for your journey into space. Stone is not an astronaut, he is a cave explorer who has explored the deepest and most dangerous caves on Earth. He wanted to prove that the cave was the best training place for space exploration. Robot DepthX With NASA's $ 5 million support budget, Stone is developing a robot called DepthX, which could become the most advanced self-propelled underwater vehicle ever. DepthX is a cave exploration robot, capable of navigating and moving in tight conditions and many obstacles. DepthX's mission is in theory to look for life on Saturn's Europa moon. Even Stone didn't dare to believe in this almost impossible task.
The manuscript journey of the great scientist Archimedes is one of the most interesting stories in the history of science. For 2,000 years, this document was "abused", ripped apart and left to waste for time. Now, a group of American historians are reviving it ... When the Roman army arrived in Sicily and later conquered Syracuse (at that time of the Greeks), a Roman soldier unexpectedly met an old man sitting calmly, despite the surrounding fighting, drawing pictures. learn and math equations on the sand. "Don't ruin these circles," the old man said. However, the Roman mercenarian not only ruined the circles on the sand but also raised the sword to kill the old man! At least that is a fairly common legend about the death of Archimedes. Historical truth is different.
Hearing of fish, how to fold the wings of ducks, geese and twins together: these are interesting research topics of anatomist Geoffroy Saint-Hilaire in the early 19th century. Behind the pretext of eclecticism is a specific purpose: to demonstrate the unity in the body of animals. It was not until 200 years later when molecular biology was born that people could prove that he was absolutely right. Biodiversity Geoffroy Saint-Hilaire is truly a nature lover. In his work as an anatomist, he immersed himself in the study of the mechanism of action of animals. For example, how can a porcupine inflate? Not only that, but he is also trying to understand broader issues and especially to build a theory of the relationship between "indeterminate currents" in the universe (light, electricity, divine flow).

Living on austere for no more than 1 USD / day as a student, but by the age of 31, Elon Musk was an Internet billionaire. Now he is at the forefront of a space race with the ultimate goal of sending humans to Mars. However, there is still a quieter, less ambitious project ahead of him: the world's first electric sports car that can outrun a Ferrari. After four years of hard research and development at a workshop in San Carlos, southern San Francisco, Tesla Motors, the first new car company in the United States in which he is chairman, prepares to launch the car. Roadster electric sports car is expected to change the whole car industry. Bold projects The project cost him about $ 27 million, and the 2-seater Roadster is expected to cost around $ 92,000. Musk said US Secretary of State Condoleezza Rice once tested the Roadster, while California Governor Arnold Schwarzenegger strongly supported the project to produce this eco-friendly vehicle. Roadster uses 6,831 lithium-ion batteries, faster than F
