The scientist who discovered resonance and the inventor of nuclear magnetic resonance

The first scientist to record resonance --- Mozi.

1. As early as the early Warring States period, people at that time invented all kinds of resonators to detect the enemy. "Mozi Beixue" records several of them:

A deep pit was dug at intervals under the base of the city wall, and a pottery urn with a capacity of seventy or eighty liters was buried in the pit, and the mouth of the urn was covered with leather, so that in fact it was made into a resonator. Let the person with a sharp hearing crouch on this resonator and listen to the movement, and when encountering the sound of the enemy digging tunnels and attacking the city, not only can you notice it, but also according to the loudness of the sound of each urn.

Difference can identify the direction and distance of the incoming enemy. Another method is to bury two leather-covered urns in the same pit, separated by a certain distance, and determine the direction of the enemy according to the loudness difference between the two urns.

2. Shen Kuo, a scientist in the Song Dynasty.

He once cleverly used the principle of resonance to design a villain dancing on the strings: first adjust the strings of the piano or ser according to the usual performance needs, and then cut some small paper figures and clamp them on the strings. When a certain string of the paper man is played, all the paper figures on the string that resonate with it will dance with the ** jump.

This invention predates its Western counterparts by centuries.

3. During the Tang Dynasty, a musical instrument hung in a monk's room in a temple in Luoyang often sounded automatically inexplicably, so the monk became frightened and became ill, and sought treatment everywhere to no avail. He has a friend who is in charge of the central government, and he went to visit him when he heard the news. At this time, I heard the bell ringing in the temple, and the instrument rang again.

So my friend said, "I can cure your disease, because I have found the root of your disease." I saw a friend find an iron file, file it on the instrument a few times, and the instrument will never sound again.

My friend explained that the instrument coincided with the resonance frequency of the temple bells, so when the bell was struck, the instrument would ring accordingly, and if the instrument was filed a little, its natural vibration frequency would be changed, and it would no longer resonate with the temple bells.

Nikola Tesla he shook down a building with resonance.

Who discovered the phenomenon of NMR? What contribution did the discovery of NMR make to the world?

In the 1930s, physicist Isidore Rabbi discovered that the nuclei of atoms in a magnetic field are arranged in a forward or reverse order parallel in the direction of the magnetic field, and when radio waves are applied, the spin direction of the nucleus is reversed. This is the earliest understanding of the interaction of atomic nuclei with magnetic fields and applied radio frequency fields. For this research, the rabbi was awarded the Nobel Prize in Physics in 1944.

In 1946, two American scientists, Bloch and Purcell, discovered that when an atomic nucleus with an odd number of nucleons (including protons and neutrons) is placed in a magnetic field, and then a radio frequency field of a specific frequency is applied, the phenomenon of atomic nuclei absorbing the energy of the radio frequency field will occur, which is the initial understanding of the phenomenon of nuclear magnetic resonance. For this, the two of them were awarded the 1952 Nobel Prize in Physics.

In 1946, Purcell of Harvard University and Bloch of Stanford University announced that they had discovered NMR. The two were awarded the Nobel Prize in 1952. Nuclear magnetic resonance (NMR) is the phenomenon of resonance absorption when the magnetic moment of the atomic nucleus acts at the same time under the action of a constant magnetic field and a high-frequency magnetic field (in the radio wave band) when certain conditions are met.

NMR soon became a high-tech technology to explore and study the microstructure and properties of matter. At present, NMR has been widely used in physics, chemistry, materials science, life sciences and medicine.

The first thing Resonance discovered was that Nikola Tesla was not right in what was said above! It's just that Tesla didn't announce it at the time, but he did an experiment and shook down a building! The principle is resonance! So it should be Tesla.

Paul C., University of Illinois, USALauterbur and Sir Peter Mansfield of the University of Mount Nottingham in the United Kingdom were jointly awarded the 2003 Nobel Prize in Physiology and Medicine for their significant contributions to the study of nuclear magnetic resonance. Their findings are now routinely used by doctors to reveal the amazing secrets inside the human body.

The award-winning research was done by Lauterbur while he was at Stony Brook University on Long Island, New York.

In 1924, the Austrian physicist Pauli (1900-1958) first discovered that certain atomic nuclei had the properties of nuclear magnetic resonance. In 1946, the American physicist Purcell (1912-1997) at Harvard University and the American-Swiss physicist Bloch (1905-1983) at Stanford University independently confirmed the NMR phenomenon experimentally. They also solved a number of related problems and put them into practical use, which led to the Nobel Prize in Physics in 1952.

In 1952, Dr. Felix of Stanford University and Edward Perserbo of Harvard University won the Nobel Prize for the theory of nuclear magnetic resonance. In 1977, vanvleck was awarded the Nobel Prize in Physics for "Fundamental Theoretical Studies of Magnetic Electronic Structures and Chaotic Systems" with Philippanderson. Kairnberg developed the theory of nuclear magnetic resonance and introduced a variety of catalysts such as neodymium to readjust the structure of the hydrocarbon chains of fuel molecules, as these respected scientists have demonstrated

Magnetism can affect and change the molecular structure, but it is not possible to save fuel by magnetism alone. Then, after his other great invention, the wireless pager, which is what we call the BP machine, Dr. Kane invented the first generation of car fuel saver FuelMax Palmas, and until the second generation of Super Holmas car fuel saver Super

fuelmax。It works on the principle of a patent-pending neodymium superconductor magnetic frequency resonator that generates a specific resonant frequency. When installed on the fuel supply pipe, the hydrocarbon chain of the flowing fuel molecules will be destroyed, so that the fuel structure molecules will be rearranged under the catalysis of neodymium compounds under the specific resonance action generated, and the original disordered motion arrangement of the fuel molecules will become a neatly arranged motion line, so that the combustion of fuel will become full and efficient.

The Super Holmas car fuel economizer Super FuelMax is made of a patented alloy. It is a combination of radiation, power, soft particle induction, Gaussian, corrective magnetic force, self-supplied energy, and resonance spectrum, and its design parameters and manufacturing process are protected by two patents all over the world. SuperfuelMAX is a local brand in the United States, with a number of world patents and authoritative certifications, best-selling in more than 100 countries and regions, is the world's first sales car fuel-saving products, has a glorious history of 25 years, its third-generation ODIC Fuelmate Super Audi Furmatt car fuel economizer, is the United States IRD company for the Chinese fuel quality level for parameter adjustment, so as to develop the most suitable for Chinese vehicles of the super car fuel economizer.

It's Tesla, and this person has been researching it 50 years ago.
