【Interesting Tales from HaiChuan Technology】Who Exactly Invented X-Rays?
Thread Content
History shows that Röntgen discovered X-rays on November 8, 1895, paving the way for the development of medical imaging technology; he was awarded the first Nobel Prize in Physics in 1901. But in fact, Tesla discovered X-rays before Röntgen, warned that they were dangerous, and refused to conduct medical experiments. Tesla experimented with X-rays using his own body; these are images of his feet that he took
In Tesla’s lightning experiments, the device used to generate high frequency, high voltage, and low current is called a Tesla coil, which is one of Tesla’s most important inventions. The principle of a Tesla coil is quite simple; it is essentially a transformer that utilizes the principle of resonance. The principle of the tuning circuit in a radio also relies on resonance, but it is used for a different purpose. Tesla used it to generate alternating current with extremely high voltage and frequency, but an extremely low current, thereby creating the effect of artificial lightning. To this day, there are still many Tesla coil enthusiasts around the world who create various devices to produce stunning and breathtaking light shows. Thus, Tesla truly deserves to be called the master of lightning. However, at that time, Tesla used Tesla coils not only for entertainment and educational purposes. He used these coils to conduct numerous innovative experiments, studying high-frequency alternating current phenomena, generating X-rays, and applying them to electrotherapy and the transmission of wireless power. Spark discharge radio transmitters using Tesla coils were widely used to transmit telegraph signals. It was not until the 1920s that spark discharge transmitters were replaced by vacuum tube radio transmitters.
After having coils that could generate lightning, Tesla had further whims and made certain modifications to the wiring of those Tesla coils, thereby inventing the radio transmitter. Later, the father of radio was considered to be the Italian physicist Marconi, but in fact it was Tesla who first proposed the concept of a complete wireless communication system. However, Tesla is not satisfied with merely transmitting signals wirelessly, like the communication technologies we use today. Today, humans have wireless telegraphy, telephone, video, and the Internet; whether it’s sound, images, or complex data, everything can be transmitted to places thousands of miles away in the blink of an eye. Communication technology has reached an extremely advanced level. However, almost all household appliances still need to be connected to two wires in order to be powered. Even the smallest phones and electronic watches that can fit in a pocket rely on that essential component – the battery. In other words, our existing radios are only \"wireless\" when transmitting signals; whereas for any transmission related to energy, alternating current is still used, transmitted through wires! A master is, after all, a master. The human civilization that we enjoy every day, one based on global communication power grids, was invented by Tesla over a hundred years ago. Something we are still unable to do today – wireless power transmission – was conceived by that master a century ago. And what’s important is that he didn’t merely foresee it or imagine it; he fought for it his entire life, spending years exploring and experimenting in an attempt to create a global wireless power transmission system, in order to realize his dream of a \"true radio.\"
Tesla said, “We need to develop ways to obtain energy from inexhaustible resources.” Humanity’s most significant advancements rely on technological inventions, and the ultimate goal of such innovation is to gain control over the material world, to harness the forces of nature and bring them in line with human needs. ”
In short, this invention is quite remarkable
Who invented it isn’t important to us. What’s important is that we can make full use of it. Haha
Right! Tesla’s imaginative inventions are unmatched, but the vast majority of them have never made it out of the laboratory; no matter how early an invention is conceived, it’s useless if no patent is filed and no product is developed. His arch-rival Edison, though driven by a desire for fame and wealth, tried to sideline Tesla and used various despicable tactics to steal his patents; yet it was Edison who truly brought these inventions to the general public.
