In 1887, the German genius Hertz successfully tested Maxwell's theory with only 4 bronze balls and became famous in one battle. Seven years later, a talented young man in Italy, relying on Hertz's thesis to overtake in the bend, crushed Tesla, and achieved ultra-long-distance radio communication in one fell swoop, bringing mankind into the "information age".
In 1861, the great Maxwell published his second electromagnetic paper, On Physical Lines of Force, leaving a miraculous prediction: "Light is an electromagnetic wave!" ”
In 1873, he created the world's "most perfect formula", Maxwell's equations.
However, this theory was so shocking and offensive to Newton, the supreme god of physics, that Maxwell was banned and had no place in the heart of Europe.
Even so, Maxwell remained a god-like being with many admirers, one of whom was the German genius Hertz.
In October 1887, Hertz's teacher recommended him to become a professor at the world-famous University of Berlin, but unexpectedly, Hertz actually refused.
He had only one reason, and that was Maxwell!
Bent on testing Maxwell's theory, he decided to stay in a small school for experiments— compared to the University of Berlin, hertz's Karlsruer Technical College was almost a pheasant university.
Pheasant University, tight funds, backward equipment, experimental equipment is even older to tears.
However, the genius Hertz actually devised an extremely simple, but amazing experiment -
An electric fire light generator, plus two large copper balls as capacitors, and then connect two small copper balls that are very close to each other through copper rods, and then add some wires, and connect a battery...
It is such a simple and shabby experimental device, but it is the most dazzling spark performance in physics.
An extremely faint electric spark jumped between the isolated receiver copper balls!
This is Maxwell's electromagnetic waves!
Before that, electromagnetic waves were illusory, invisible, and untouchable.
At this moment, Hertz graciously invited electromagnetic waves to appear in the world, and was the first to see it with their own eyes!
Electromagnetic waves, out of nowhere!
Maxwell ascended to the altar and stood shoulder to Shoulder with Newton.
Unfortunately, Hertz did not have time to witness the contribution of electromagnetic waves to mankind, and died young in 1894.
He was only 37 years old that year!
It was also in that year that a 20-year-old italian genius young man went on vacation to Lombardy and accidentally read Hertz's paper on electromagnetic waves.
This young man, his name was Galilmo Marconi.
When Marconi saw the first glance of hertz's paper, he knew he had picked up the treasure, and he saw the future of wireless communication in electromagnetic waves.
At that time, there was actually another god man who was also playing radio communication, and played earlier than Marconi, and played better than Marconi...
This god man is Tesla!
In 1900, Tesla launched one of the craziest projects in history, the Global Wireless Power Project.
He asked the world richest JP Morgan to invest 150,000 yuan, borrowed another 1 million yuan, and built a large Tesla coil on Long Island, ready to provide wireless communications and wireless transmission services to both sides of the Atlantic.
At this time, Marconi turned out to be born, relying on Hertz's thesis, suddenly achieved a curve overtaking, standing at a height comparable to Tesla.
In just 2 years, Marconi was able to get the radio communications in place – albeit over short distances, and could only perform in public.
But he keenly seized the opportunity, set up his own company, and got a patent.
At the same time, Tesla's lifelong enemy, Edison, also found Marconi and decided to invest — partly to make money, and on the other hand, to suppress Tesla.
In this way, Marconi and Edison joined forces, in less than 1 year, defeated Tesla, and first realized ultra-long-distance radio communication across the Atlantic, bringing the entire human race into a new "information age".
In this process, Hertz, standing behind Marconi, is definitely a great achievement. In a sense, Hertz laid the foundation for the entire modern civilization of mankind!
In addition, Hertz's experiment not only confirmed the existence of electromagnetic waves and the emergence of radio communications, but also revealed another "ghostly" existence - quantum!
It wasn't until planck, the most handsome physics genius in history, was born that the specter of "quantum" was awakened, stirring up the wind and rain in all directions, and even almost pulling the great Albert Einstein off the altar!
About hertz, Maxwell, quantum and other physics legends, are all popular science in the best-selling book "Did God Roll the Dice". In the book, from Newton's gravity, to Maxwell's theory of electromagnetism, to Einstein's theory of relativity, then to Bohr's quantum theory, to the parallel universe and the theory of hidden variables...
This is an introductory book on quantum theory, Douban 9.2 points of fun science popularization god work, the author Cao Tianyuan is also a god, hard to write the boring physics of the style of martial arts.
In this book, physics giants such as Bohr, Einstein, Schrödinger, Heisenberg, and von Neumann are like the world's best masters in martial arts, using stunning theories as weapons to create a world of swords and swords, and magnificent waves!
I stayed up all night to finish this book, because it was really exciting, just like my friend said when he recommended this book to me- "Just read it as a fantasy novel like "Shade of heaven"!" ”
If you like to read novels, you will definitely fall in love with this book, the degree of excitement is not inferior to Jin Yong martial arts, and you can also increase your knowledge.
This book is very easy to read, as long as you have a knowledge of junior high school mathematics. Whether it is to read it yourself or to send it to relatives and friends, it is very suitable.
Books are not expensive, a meal money only, like friends do not miss, link below, self-pick-
God rolls the dice is fun science
