00:00Nikola Tesla was not humanity's greatest genius. That's my honest and personal opinion after
00:06everything I've read. I'm here in a different setting and there will be more videos like this
00:11made in a different environment. Today it's about Nikola Tesla because many of you have
00:17asked me to share my opinion about Tesla. What do I think? So this is today's video in which I
00:24try
00:24to show you that maybe we're not. Nikola Tesla was a genius but I don't think he was humanity's
00:29greatest genius at least on the technical side I mean. So I believe that people like Einstein,
00:34Newton and even Edison surpass Tesla. So stay with me until the end of the video to find out why.
00:43To begin with let's talk about a fundamental difference between discovery, invention and
00:49innovation. Because that's how we identify history's greatest geniuses. But what does it
00:55mean to make a discovery? It means to discover laws of nature as well. These were assumptions
01:00that you didn't know. Newton was a discoverer because he discovered the laws of mechanics.
01:06Einstein was a discoverer because he discovered the theory of relativity. They were in nature.
01:11No one knew about them. Einstein came and brought them to light, showed their mathematical form and
01:16today we especially talk about the laws of electromagnetism. And the greatest contributor
01:22to the laws of electromagnetism was Maxwell. Because he was the first to write down the form of all the
01:28laws of electromagnetism. And we're especially talking about Maxwell's four laws. So Maxwell is a
01:35discoverer. Sure there were others before him but he was the one who finally wrote the equation.
01:40He is a discoverer in the sense that the laws of nature existed in nature, people didn't know what
01:46they were. And then he, together with those before him, discovered their form and wrote them down on a
01:52piece of paper as mathematical equations. Because all the laws of nature when we talk about science
01:57must have a form that is written as mathematical equations.
02:02An inventor, on the other hand, is the one who takes the equations already discovered by a discoverer
02:10and puts them to practical use. Right? We can imagine that an inventor takes the laws of
02:15electromagnetism and uses them to build an electric motor. Because the electric motor is useful. Right?
02:22Or he takes the same laws of electromagnetism and builds a light bulb. Right? He is an inventor.
02:29He invents based on the discovered laws. So in this sense we have Edison who is an inventor because he
02:36was
02:36well among the first to make a light bulb work in a practical way. Yes, using Maxwell's laws.
02:44And we also have the inventors of electric motors who also used Maxwell's laws to build motors. And here
02:51we have the case of Nikola Tesla who is an inventor like Edison. Because as we will see Nikola Tesla
02:57was
02:57the first to build a three-phase motor. Yes, with three phases which was very efficient. So he used the
03:04laws
03:04of electromagnetism to build a motor. And the third level, and I would say the lowest one, with your
03:12permission, yes, are the innovators who take inventions that are already in use and reuse them for something
03:19else. Right? Let's imagine that someone has already made an electric motor. Then you can use that electric
03:25motor in a car. Or you can use it in a mechanical toothbrush. Or you can use it in a
03:30fan.
03:33So innovators, those who make innovations are the ones who take the inventions of inventors and use
03:39them for slightly different things. They combine inventions to make something new. They are innovators.
03:45And with your permission, I am one of them too. Because what I did when I first built that green
03:50light
03:50sensor into a watch in such a way that it measures the pulse in a watch in all smart watches,
03:57that was an
03:58innovation. Because I took something that someone else had invented, right? In this case, we're talking
04:03about green light LEDs. I also took other things invented by others. In this case, we're talking
04:09about the inertial sensor, which I integrated into the watch for more accurate measurement. And I took
04:14all sorts of other inventions, put them together, right? And I created an innovation. I mean, for the
04:19first time, I built a watch capable of measuring the pulse using only a single optical sensor, the one with
04:26the
04:26green light. So the third scale is the innovator scale, the Tesla of the innovator. Edison of the
04:32era. Today, we're talking about Nikola Tesla, who was an inventor. So somewhere between a discoverer and
04:39an innovator, there was also another inventor we'll mention who is Edison. And of course, we can ask
04:45ourselves which of the two was greater. Now, however, it's important to say from the start that both
04:52Nikola Tesla and Edison were born at a time when inventions in electricity were booming.
05:00Because Maxwell's laws had been finalized somewhere around the 1800s. So basically,
05:06in the 19th century, towards the end of the 19th century, Maxwell would finalize the laws of
05:12electromagnetism. And so these innovators who now knew the equations, right, they could make inventions
05:19with them. And that's when we have the explosion of our human civilization, which is a civilization
05:24based on electromagnetism. Right, right, right, right, right, that's another discussion. In the
05:30meantime, we know a lot of laws, both those of quantum chromodynamics and those of quantum
05:34electrodynamics. But our civilization even today, mind you, mostly uses the laws of electromagnetism,
05:41right? So basically, both Edison and Nikola Tesla appeared shortly, just a few decades after
05:47Maxwell had completed the equations of electromagnetism. And by knowing those equations, they were able to
05:53make inventions. For example, he used the laws of electromagnetism to build a phonograph,
06:02to build an electric lighting system, to make the first practical light bulb, and so on.
06:11On the other hand, when he arrived in America,
06:14he became an advocate and found himself in the middle of the alternating current revolution.
06:20Because, I forgot to mention, Edison was working with direct current and he was creating direct
06:25current electricity distribution systems. It's just that this direct current has a problem.
06:31When you want to send it over long distances to provide light and electricity to people, you have
06:37losses throughout the network, right? And what is the loss along the network? It is given by the formula,
06:44by Ohm's law, which tells us that the energy loss is the resistance multiplied by the current squared.
06:51So this is the power that is lost through thermal effects due to the heating of the wire. So the
06:56current passes through and it heats up. And you can see in this formula that what is lost? Yes. So
07:02the
07:02electric power that is lost is proportional to the square of the current. So the higher the electric
07:09current, the greater the losses. And you realize what happens that Edison, in his electric power
07:16distribution systems, wanted to send electric current to the whole neighborhood through a single
07:20wire, of course. And then through that wire, a lot of current would flow through the electric conductor
07:27and current squared means a lot of electrical losses. And it's not a very efficient system. It's not a very
07:33efficient system. Well, and this is where not only Tesla comes in, but also the engineers before him
07:40who had already developed the idea of an alternating current electric system. So what does alternating
07:47current mean? It means that over very short periods, the electric current or the direction of the electric
07:52current changes, right? Sometimes to the left, sometimes to the right, sometimes to the left, sometimes to the
07:57right, with a frequency of about 50 hearts in our networks in Europe. This alternating current has a big
08:03advantage. The fact that it can be stepped up with the help of transformers. That's why if you go out
08:10in
08:10the countryside, you sometimes see transformers that lower or raise the voltage, right? Because this time,
08:16in the alternating current transmission system, right, when we want to send electricity to a neighborhood,
08:22we send it through high voltage power lines. Well, if we send it through high voltage power lines,
08:30the current will be lower for the same power that we transmit, right? Because power is essentially the
08:36product of voltage in current. And if the power line is high voltage, then the current that passes through
08:42is lower. And what does that mean? Do you remember the previous formula? Well, that means the electrical
08:47losses are smaller because the electrical losses are proportional to R times current squared. So if
08:54this time on the high voltage power lines, the current will be lower, that means the electrical
08:58losses will also be lower, right? So this is the big advantage of alternating current. The fact that we can
09:05amplify it through transformers, we raise it to a very high voltage, and then the intensity of the
09:12electric current through the conductor is lower, and then the electrical losses will be smaller.
09:20When Nikola Tesla arrived in America, he arrived exactly at the moment when the supporters of
09:26alternating current were gaining ground. And there was a very strong fight there between the supporters
09:31of alternating current, the newer supporters, and the supporters of direct current who were on Edison's
09:36side. Let's say, hey, you have them, all my old ones. And in the end,
09:41the supporters of alternating current won, because indeed, today's distribution networks use alternating
09:47current. No. Well, and here comes the first serious invention, and in fact, the greatest invention made by
09:55Nikola Tesla. Namely, the polyphase alternating current motor, as it was called at that time.
10:03Today, it's usually three phase. What does this mean? Well, it means that if we have an electric power
10:11distribution, instead of having just two wires that carry the electric current, we have three wires
10:17today. Today, the electric power distribution system is three-phase, because there are three wires,
10:24and the electric voltage between the three wires is constructed in such a way that there is a phase
10:29shift between them. And what did Nikola Tesla do? Well, he took advantage of this fact to build very
10:36efficient electric motors. Because at that time, from Edison, electric motors used direct current.
10:42And by using direct current, they used all kinds of brushes. And those brushes produced sparks,
10:48they would break down, and so on. So, okay, let me put it briefly. If a motor, essentially, is built
10:54from a stator, and in the center has a rotor. So the stator is the part through which the electric
11:00current
11:00enters, and the rotor is the central part that spins. Now, in the direct current motors that Edison built,
11:07that rotor, yes, which had to receive electric current. Because the electric force is given by
11:12the magnetic field generated by the stator, and by the electric current that passes through the rotor.
11:19So, that rotor needs to receive electric current. And in direct current motors, that electric current
11:24was supplied through brushes, through some brushes. Because the direction of the electric current had to
11:30change. And so, they used some contactors, some brushes, and there, at that contact point,
11:35you always had problems, right? Nikola Tesla basically took this idea of the electric motor
11:43with a stator and a rotor, but he built it for his three-phase system, right? And how is his
11:49three-phase
11:50system built? Well, basically, in the stator, we have three coils through which the three phases of the
11:56electric current pass. And because those phases, because these voltages are out of phase, this
12:02electric current creates some magnetic fields that are in a single phase pulsating, but they are also
12:08rotating. Because there's a phase difference between the three, a magnetic field is created that both pulses
12:14and rotates. And this is very important because in this way he can build, I'm talking about Tesla,
12:21yes, a stator that is very simple. In the case of the alternating current motor, polyphase, in our case,
12:29three-phase, yes, the rotor, the one in the center, yes, no longer receives electric current from the
12:34outside. As it was in the case, as it was in the case of direct current motors, the ones made
12:39by Edison.
12:41So, it no longer receives direct current from the outside, and, but it is built from, let's say,
12:46some bars, just some electric bars. And the electric current that passes through the rotor there is
12:53essentially electric current induced by the pulsating and rotating magnetic fields of the stator,
12:59right? The result is that this motor works because this pulsating and rotating magnetic field generates
13:07currents in the stator. These induced currents, uh, of course, have electric current in them,
13:12and then the magnetic field of the stator acts on the induced currents and sets the rotor in motion.
13:19So, we have an electric motor built by Tesla, since that's who we're talking about, which has many
13:25advantages. First of all, the rotor no longer has fields, so we don't have brushes and all sorts of
13:30electrical contacts there anymore. So, simply put, that rotor lasts a very long time. You don't have
13:35to do anything. The stator has fixed electrical contacts, and so it becomes a very reliable electric motor.
13:42On the other hand, it has been proven that this is an electric motor with a rotation speed
13:47determined by the frequency of the electric current, which is very stable, and on the other hand,
13:53it is a very reliable electric motor. It lasts a very long time. So, this is Nikola Tesla's great
14:00invention, right? The polyphase electric motor, in our case the three-phase one, which is indeed a very,
14:06very reliable electric motor, and lasts a very long time. And here I'll add just a little about
14:14the alternating current electric motors that we have in our household products, like in a sewing
14:18machine, for example, which note is not three-phase, but single-phase. And that's very interesting,
14:24because they are alternating current motors, and today's motors are the same way. A rotor, yes,
14:32which doesn't have electrical contacts, because there the current is induced by the single-phase
14:37alternating current system of the stator. Just keep in mind, normally such a system,
14:43with a stator that only has a single phase, creates a pulsating magnetic field, but it doesn't create a
14:49rotating magnetic field. So, in that case, you shouldn't expect the rotor to start. Well,
14:55in order for the rotor to start, actually, in these single-phase AC motors, there's another trick that's
15:01used. That means an extra coil is added, right? And through that, a current is passed, which is
15:07actually phased with the help of a capacitor, in such a way as to create, so to speak, a kind
15:12of
15:12pseudo-rotating magnetic field, which will start and generate that initial rotational torque of the
15:19rotor. And once started, this single-phase motor spins, and, well, the rotational frequency of the rotor
15:27is also approximately given by the rotational frequency of the alternating current, roughly,
15:34since there's a minor phase shift. The advantage, of course, is that this time, I can power the motor
15:41from a single-phase network, basically the one we have at home. However, the difference between the polyphase,
15:48three-phase motor of Nikola Tesla, and this new motor, let's say, which appeared later,
15:54yes, the single-phase electric motor, remains. In the sense that, from what I've read, three-phase motors
16:00are always more reliable and durable. They last longer and are more powerful. Because of this,
16:05three-phase motors are used when you need a lot of power. So, all the industrial motors used in factories
16:13where you need a lot of power are usually three-phase. And single-phase motors, which have only one phase,
16:21are the ones we use at home. And now let's go back to Nikola Tesla, because besides the polyphase,
16:28three-phase motor, he had other inventions as well, but not all of them were such a big success.
16:33And I wrote down a few here. For example, I wrote down the radio control. The fact that he was
16:40one of
16:41the first to try to remotely control an object using radio waves. That doesn't mean he can be defined as
16:51the inventor of radio control, but he was one of the first who tried it, and he tried it successfully.
16:57Of course, there were others who tried as well. He had a lot of patents, so Nikola Tesla had around
17:02100 or so patents in the United States. Worldwide, he had about 300 patents.
17:09By the way, Edison had more. Edison had over 1,000 patents in the United States. Tesla had only about
17:16100. That's also because I forgot to mention, there's a difference, a difference between Nikola
17:21Tesla and Edison. Nikola Tesla was, how should I put it, this kind of inventor who has a vision,
17:28who imagines things and tries, and maybe it works. Edison had this attitude of a capitalist inventor,
17:36an inventor who knows how to go in a direction where there's a lot of money, who is able to
17:41build,
17:42how should I say, an entire building, an entire company, that goes towards the idea he thought of.
17:48So Edison was a man who was a very good organizer and who, besides being a genius inventor, was an
17:54inventor who managed to gather people to build companies, to go much further towards ideas,
18:00this idea of a capitalist inventor. So as I was saying, Nikola Tesla was more, this idea of an inventor
18:06who was more singular, solitary, so to speak, right? Who has a vision, who tries to do something,
18:12who seeks help from people, but not necessarily the kind who, by himself, sets up really big things,
18:19companies and so on. That's because, well, it also fits with the myth of Nikola Tesla, who is a man
18:24ignored by others. But now let me go back to other inventions of Tesla, and I wrote down here,
18:31for example, lighting with high frequency currents. He had several invention patents for high frequency
18:38lamps. And from what I have read, very few of those invention patents were actually used in practice.
18:45So basically, his inventions were not actually used in practice when it comes to high frequency lighting.
18:54Another invention that is often talked about when it comes to Nikola Tesla,
18:58is the transmission of energy over very long distances. So I'm going to talk more about this,
19:04because there are some people who believe that he discovered free energy, that he could transmit
19:08and obtain energy for free. No, he didn't do anything like that, since we know energy can't come from
19:14nothing. Energy is transferred, right? Still, it's clear that you have to get it from somewhere else,
19:20and it costs you to get it from somewhere else. So in the end, no, the idea of free energy
19:24doesn't
19:25stand. But the idea of transmitting energy through the air over long distances, that was something
19:31that fascinated Nikola Tesla. And the story is real. Indeed, he even built a very tall tower,
19:38a lot of money was invested, in which he tried to transmit energy over a very long distance. And
19:44basically, that tower used some of the same principles that he used in the coils he discovered.
19:50Just like that, the coils come to mind. Specifically, it used some resonance principles,
19:54because he had an idea. As I said, he was a kind of visionary engineer. And he had this idea,
20:00he thought like this, the Earth is like a resonant cavity. There should be a resonance between the
20:06Earth's surface and the upper atmosphere, right? And if I use that resonance, then I could send and
20:13receive energy everywhere, let's say, over the Earth's surface, across very great distances.
20:21Currently, there are ideas from pseudoscience that such a resonance exists. I don't even remember
20:25what it's called anymore. Resonance, Schumann, and so on. But the truth is that from a technical
20:30point of view, even if you can define a certain resonance in such a case, the quality factor of that,
20:36of the resonance system is very low. So in practice, the resonance is so small that you really can't
20:43make use of it. But well, these things Nikola Tesla didn't know them very well. As I said,
20:51he was a visionary engineer and he imagined things for the future, but he didn't know them that well.
20:56And maybe there could have been a chance for these things to be true, but they didn't turn out to
21:00be
21:00true, right? So at the moment when he built that huge tower and tried to send energy over a very
21:06long
21:06distance, and of course, we're talking about a lot of energy, not just a little, because a small
21:11amount of energy can't be transmitted. It doesn't send energy to satellites, right? To communicate
21:15with them, every time we send signals to satellites, we're not sending them energy. It's just that the
21:20energy is very, very small, just enough to communicate. We're not discussing that. We're talking
21:24about a lot of energy, right? So with that, with that tower, it didn't manage to send energy the
21:30way he thought at first for a few kilometers, a few dozen kilometers and so on everywhere in the
21:34community. There was no way it could work, right? And there was no way it could work. We know that
21:40and
21:40why? Because that resonance system doesn't exist. The earth is not a resonance system, right?
21:45So he was on the wrong track. And we know that if you want to transmit energy, you can do
21:50it through
21:51the old method of induction, right? That's how we heat up. That's how we charge our phones wirelessly,
21:56right? Because our phone has a receiving coil and the charger has a transmitting coil. And as long as
22:02the two coils are close to each other, then the coil that transmits energy, right? It can induce
22:09current in the receiving coil, in this case, our phone. The whole idea is that the distance between
22:14the two is small, right? So transmitting energy through the air is possible. We also have it in our
22:20phones. It's just that the distance between the objects is small. And this dream of Nikola Tesla,
22:25to transmit energy over very long distances, has not yet been achieved.
22:31And what can I say? I still hope it will happen because you see we have all kinds of electrical
22:37devices in our homes. And we always have to use the cable, right? And I believe that in the future
22:43it could become a reality. People try various methods since the energy only needs to be transmitted
22:48within the house, not over long distances. I mean, literally just a few meters. People keep trying,
22:55but this isn't about laser systems. But I'll share something from my own experience, just to put it
22:59that way. Because at Philips, I worked on such a project, which is called wireless kitchen, meaning
23:04the wireless kitchen. And in that project, my goal was to take a coil, just to tell you what the
23:10wireless
23:10kitchen looks like. So you can get an idea. The kitchen of the future in which that's it to have,
23:18how should I say, all these kitchen appliances no longer need electrical cords to charge. I mean,
23:24if you buy a kettle, you shouldn't have to plug it in anymore. And the idea of the wireless kitchen
23:29essentially is simple. It's the same as with mobile phones, namely that you need an energy transmitter,
23:35which in the case of the wireless kitchen, sorry, is a coil that is placed under the kitchen countertop.
23:41So if we have a kitchen countertop, we put a coil under the kitchen countertop. And this water one,
23:49so the water kettle has a coil at its base, which is a receiver, which receives the current, right?
23:56And then if we place, we place the kettle exactly on the spot on the countertop where the coil that
24:03transmits energy is underneath, then we have an energy transfer. And basically the kettle can receive
24:10energy wirelessly. It gets it from the coil beneath the countertop. So this system is very
24:16similar to these induction cooktops that we have, because that's how induction cooktops work. So we
24:22have a coil through that cooktop. And in this case with induction cooktops, we don't have a receiving
24:27coil. It's simply the induction coil inside the cooktop. It induces electric
24:33currents in our pot, which is metallic and thus heats up and let's say heats the water. Yes.
24:38So with kettles and as I told you, the other things in the kitchen, so in the wireless kitchen,
24:43we'll basically have induction coils under the countertop and we'll have appliances above that
24:49have receiving coils, right? So this would be, let's say something that can be done, something I've
24:54worked on and which will probably appear on the market without a doubt. But once again, it's not what
24:59we want at home. I would like to charge all these things at home, all of them, without plugging
25:04anything into an outlet. There is still work to be done, maybe it will be achieved, but Nikola Tesla's
25:09idea, yes, of transmitting over very long distances, that is very, very hard to accomplish and not in
25:15the way Nikola Tesla imagined it, because once again, the earth is not a resonator.
25:21And you see, this is what happens when I speak freely because I talk a lot, that's how it is.
25:26But you should know that I might make more videos like this. I realize that now the phone is moving.
25:33Yes, next time I'll make sure it doesn't move. We've reached the end and I'd just like to talk
25:39about a few myths about Nikola Tesla and I'll start with scalar waves. It's something that followed me
25:45when I was at the electrical engineering faculty, because it was said that Nikola Tesla had discovered
25:51scalar waves, which was supposed to be something beyond the known electromagnetic waves. And while
25:57looking into it a bit for this video, I found out what it was about. Back then, I didn't understand.
26:02Now, I kind of understand. Nikola Tesla had some patents for transmitting energy, right?
26:09And he didn't mention scalar waves. However, later on, some physicists supposedly said this.
26:15Tesla's system could have worked or would work if these scalar electromagnetic waves exist.
26:22And I'll briefly tell you what electromagnetic waves are and why these scalar electromagnetic waves
26:28don't exist. At least they don't exist right now. And I don't know if they will in the future.
26:32The basic idea is as follows. Facts. All electromagnetic waves are transverse electromagnetic waves.
26:38Because if we take the electromagnetic field, the electromagnetic field oscillates.
26:42Either in this direction, along the direction of motion, or in a horizontal direction perpendicular to
26:48the direction of motion, or in a vertical direction perpendicular to the direction of motion of the wave.
26:54That's why electromagnetic waves are transverse, right? And at some point there were some suggestions
27:00from these physicists who said, if we start and calculate the electromagnetic waves,
27:07not for the electric fields and magnetic fields, so not for E and B, but for the vector potentials
27:13that exist in the description of electromagnetic fields. There is a deeper thing that says behind
27:19the electric and magnetic fields there are electrodynamic potentials, which are of two types.
27:25The electro, electro, the electrodynamic scalar potential, and the electrodynamic vector potential,
27:31let's say, right? Well, essentially then we have four such potentials, and if we make waves out of them,
27:37we will have four waves, right? So we can have not only transverse waves, but we could also have
27:42longitudinal waves, and these waves would be scalar waves. Just be careful. In electromagnetic fields,
27:50in Maxwell's laws, we don't need these scalar waves, right?
27:53Yeah. And so because of this, it said that, okay, this hypothesis of scalar waves is not the correct
28:01one, and some people call it the hypothesis of pseudoscalar waves, right? And again, coming back to
28:07Tesla, they don't come from Tesla, but I just want to say a very, very brief thing about scalar waves,
28:14because I was thinking that if we're talking about these scalar waves in the case of electrodynamic
28:19potentials, right? So the electrodynamic vector and scalar potential, then we should get into the
28:25theory of quantum electrodynamics. And there it's very interesting, because in the theory of quantum
28:32electrodynamics, when waves are obtained, you really do get waves. Waves, longitudinal ones, besides the
28:38two transverse ones, and you also get temporal waves. Yes. Well, in quantum electrodynamics, however,
28:45a normalization takes place, I can't remember exactly how it's called, which is named after Gupta
28:51Blula, right? In which, if we were to associate photons with those waves that are longitudinal,
28:56and with those waves that are temporal, so in time, the two would annihilate each other, and we would end
29:03up only with the transverse waves, right? This is something that I also find hard to understand in
29:09quantum electrodynamics, but that's how nature is built. Nature is built so that those so-called longitudinal
29:15photons and temporal photons annihilate each other precisely in quantum mechanics, so that we only
29:21have transverse photons, right? But this makes me think of Tesla, who said, well, not Tesla, but those
29:27who came after him, who talked about these scalar waves, but pay attention, what if in the future,
29:33future civilizations somehow managed to get out of this Gupta Blula paradigm, right? And talk about these
29:40photons that are longitudinal and temporal, which maybe, I don't know, in another much more advanced
29:46theory, maybe they don't annihilate, right? That doesn't mean that Tesla discovered scalar waves,
29:52right? Because Tesla essentially was in the classical paradigm in Maxwell's paradigm. And as I told you,
29:58in Maxwell's paradigm, there's no question of having scalar waves. Electromagnetic waves are only
30:04transverse, given by the two polarizations of... And finally, a few of the myths I've found, you see,
30:13about Tesla, right? What did I find? I found this. The death ray, which is believed to bring world peace
30:22precisely because it could destroy cities and armies in an instant. Tesla himself is said to have spoken
30:28about his weapon. My device allows me to send to a very distant point energies trillions of times
30:34greater than is possible with any kind of rays. Thus, thousands of horsepower will be transmitted
30:40through a beam thinner than a hair, and nothing can withstand it. Yes, that's because at that time,
30:47Tesla was in that paradigm of transmitting energy over very long distances wirelessly. And if his
30:53paradigm had proven to be true, then maybe he could have done something like that. But the paradigm,
30:58as we've seen, is not true. The initial hypothesis was false. So, this text
31:04about Tesla can't be fully interpreted if you want to think of it in terms of lasers. Because when
31:08he talks about a beam, he's talking about a beam thinner than a hair, right? Then, yes, you can say
31:15that a laser beam can carry energy over very long distances and can destroy things. But again, in
31:21Tesla's time... Tesla? Uh... Okay, now I have to think about it because Einstein's ideas about lasers were
31:28developed when Tesla was already very old. So, it's possible that Tesla heard about lasers. But I don't
31:35think these ideas were developed before, I believe, as it was stated here, before Einstein developed that
31:42idea of lasers and that power inversion you need in order to create lasers afterwards. So, only within the
31:50paradigm of the laser. But Tesla is not considered in any way an inventor of the laser, because he worked,
31:55as I told you, within the paradigm of classical electromagnetism. Another myth. Tesla was the
32:02coordinator of the Philadelphia project. The Philadelphia project, which supposedly made a
32:06ship, a vessel disappear, yes, with the help of Einstein. I also have a video on YouTube. You can
32:13check it out there. I don't believe in this Philadelphia project. I think it's a myth. And that's
32:17why I don't think Tesla was the coordinator of this project. Again, I only found random words thrown
32:22around. I couldn't find any reference at all that Tesla could have done something like this. So, it's a myth.
32:31Another myth is that Tesla laid the foundation for the world's first particle accelerator based on
32:37the principle of ball lightning, right? Here, I'm not denying that Tesla could have used the principle of
32:42ball lightning to accelerate particles, right? In modern physics, for example, today we have lasers that
32:50accelerate particles to very high energies, precisely because they use that wave of potential which
32:58helps that particle accelerate. And I imagine that Tesla could have used the principle of ball
33:05lightning to suggest the idea that this ball lightning could accelerate particles. But not at,
33:14I wouldn't call him the inventor of the particle accelerator, because in physics,
33:18in particle physics, the first accelerators used other principles, right? So, the fact that he
33:24suggested something that later on might have been realized in another form, that doesn't make him an
33:29inventor. That he was the one who laid the foundations of the first particle accelerator in the world.
33:36Also, I have something here about radio, that Tesla supposedly discovered radio before Marconi.
33:43The truth is, from what I've read, that neither Tesla nor Marconi discovered the radio, that actually it
33:48happened as it often does in science. A lot of people contribute to certain things, and at some point,
33:53one of them puts the final brick in place. So, it seems that person is the inventor. In this case,
33:59Marconi seems to us to have put the final brick in place when we talk about radio, not as a
34:04principle,
34:04but about radio as something practical. Although Marconi, so to speak, laid the last brick in building the
34:10practical radio we needed. But after that, Marconi, I read that he was sued by some of those who also
34:15had invention patents and contributions. And the judge concluded, based on, well, the things that
34:22were discussed there, that indeed Marconi cannot be named as the sole inventor of the radio. And I
34:28think that's true for Tesla as well. Tesla may have had certain ideas, but honestly, I don't think
34:34Tesla had any very clear invention patents that would have led to the practical construction of
34:40a radio. I haven't read about these things, right? So, again, I think it's about some people.
34:47The conclusion from all these stories, right, about Nikola Tesla. Nikola Tesla was a genius,
34:53but I place him in the category of engineering geniuses, right? Geniuses who make inventions. As I
35:00told you, remember the beginning, we have discoveries, inventions, and innovations. Most activities
35:05worldwide today focus on innovation, because most inventions have already been made, they've been
35:11done, and the discoveries were made more than 100 years ago. So Tesla was a genius of inventions,
35:17just like Edison was. And if we compare the two, then Edison was still, no, sorry, Edison was much
35:23greater than Tesla. On the other hand, I wouldn't put Tesla above Einstein, above Nuremberg,
35:29above Nixon. Because on one hand, to make inventions, you need those fundamental things, right? And those
35:36were discoveries made by the great physicists of the world. On the other hand, you make inventions
35:42when you're in a time of inventions in the field of restorative. And Tesla lived exactly in the period
35:49right after just a few decades later, he was prolific after the equations governing that world had been
35:55finalized and when everything was exploding. This civilization of electromagnetism, as I call it,
36:01is the civilization we live in. So he was in that period when it was exploding, and simply there were
36:06a lot of inventions being made with electricity at that time. And he was one of the great inventors of
36:11that period. And I compare it to the period we live in today, because even now there are some inventors,
36:18and this time I call them the inventors of artificial intelligence, right? Because they can create
36:24inventions based on fundamental principles of mathematics. And the invention right now is
36:30artificial intelligence, large language models, these models, right? And the innovators are those
36:35who use them. Yes, so all of us who use APIs and build all kinds of interfaces and make use
36:41of
36:41artificial intelligence like CGPT cloud. We are the innovators. The inventors in today's case are those
36:49who write those fundamental codes for the cloud. Those codes, of course, make use of discovered laws,
36:56mathematical laws, and so on. So even today, we are living in an age of inventors. And the great inventors
37:03of today, yes, are those who invent artificial intelligence. So they are the ones from these companies
37:09we're talking about open AI cloud and so on. And to conclude, yes, in my opinion, Tesla Nikola Tesla
37:15was a genius, but he was a genius among inventors, a genius who lived in that period and was shaped
37:21by it.
37:23And with that, we've reached the end of today's video, a more special video, I will adapt to be
37:29honest to this method of making videos, especially because I would like to extend it to other types
37:34of videos as well. The big disadvantage is that I talk a lot, but probably in the future when I
37:40make the other types of videos, because I would like to switch to making one more video per week
37:45on another topic, not just physics, where I speak the language. Yes, I will try to keep those videos
37:51shorter here so I don't talk so much. Well, since we've reached the end of this video, don't forget to
