Ist die Physik auserforscht? | Harald Lesch | Terra X Lesch & Co
speed of light x-rays will be discovered there is 1874 the two will talk in munich will anyone suggest that there must be two different types of electrical charges in atoms? yes one would be negative the other would be positive 1874 maybe they both knew nothing about it especially physics but from then on the question becomes more and more urgent how can that be when electrons are negative and atomic nuclei as a result? they are positively charged why do electrons not really fall into the atomic nucleus, think about it, such a fundamental question as the stability of the world is completely unresolved and then you sit down, one says, with the physicist, everything is already somehow, basically, we already know everything, none of that, and this young man is allowed to do that, I can finally tell you now In 1900, Max Planck basically published a work on something very simple, namely, on the radiation of a luminous body, the radiation spectrum of a luminous body of a wire and who had to tell you and the spectrum had to have the identity distribution compared to frequency or compared to wavelength, he made an assumption that, as he himself writes, he could only make in a state of great despair because there was no alternative left, he actually said that energy, i.e. radiation, is emitted in the form of squawking in packets of packets of energy only five years later. s, Albert Einstein will say that not only the release of photons occurs in the package farm, but also the absorption of energy occurs in the form of a package, so light is already using the term photons, light is not a wave or not just a wave, but also has the property of sending photons and when to do it. think about photovoltaics today there is the photoelectric effect in it i.e. light can release electrons from a metal surface and this movement of electrons can use this electric current imagine this 1905 discovery is possibly the lifeline for humanity if we finally started renewable energy really global use namely transforming the sun's energy into electrical energy and that was invented at the time with a revolutionary idea about the transformation of light into energy or the way light interacts with matter, one you may wonder where physics is going now in the future, of course it is true that physics is in principle a big building of hypotheses and these hypotheses have to be verified again and again, they have to be confirmed etc. high is only in G On the other hand, you can be sure that, so to speak, these are the hooks that have actually been hammered into the rock where you can stick them on future climbs and you won't fall under them any further, but you can fight for completely different new heights because that is exactly Exactly these hooks perhaps could have already been nailed to the granite wall of knowledge of granite physics and that is my genuine honest conviction that physics will play very different roles in travel of discovery in the Himalayas of scientific discovery or technical development physics will always be the base camp because it has clearly formulated the basic properties of matter and the interaction of radiation with matter, it knows where we are in space and time, how movement behaves, etc. , and she will always be the one to, to some extent, then when another F the research area runs out of air a bit how an oxygen tank works and, as it were, to return to the physically recognizable and understandable where we are, for Of course, with every science that has been around for a while, there is always the The problem is that there is more and more information available to those starting out in this field in the form of training at universities, colleges and the like who have to master it, I mean, in In Newton's time you could only study mechanics, but physics was over quickly, so to speak, it took the first semester, so to speak, but as time went on he got more and more into it, then electrodynamics and thermodynamics and then all these other areas started: atomic physics, physics, astrophysics, hydrodynamics. and so on but everything got added more and more and more apps got added too which means all of a sudden of course it's getting harder and harder for the individual the individual here or the to keep track of things there is no use in simply saying what you already know but if you want to know something new then you need specialization specialization so to speak the price you have to pay for research progress but at some point this price will of course go higher and higher because, for example, through specialization, communication is more and more difficult not only within science but also with society, so how can this specialization of a saturated and fully developed natural science be dealt with? without losing this knowledge? to keep doing something new, what could be the new, the new would of course be the interdisciplinary and what is often called holistic, so the whole cannot simply be the sum of its parts, the processes that have place between parties must be more interesting suddenly nowadays it is becoming more and more prevalent since Tipping Points especially when it comes to climate change people talk about tipping points but this can only be understood if you connect parts of the earth system with each other, the hydrosphere, the waters that flow and are stagnant, or the cryosphere, the kingdom of frozen water and How is everything connected to the lithosphere?
So in the upper area of the Earth you have to look at the earth system is physics perhaps the best way to become a systems science which means one thing you shouldn't forget is knowing the individual parts. exactly or we are very good at physics the accuracy the precision of physical measurements if i can shoot again at that point its really inhumane when you think about it i still have to tell you i mean you have seen it before s video but if you think about it the black holes will merge in 1.3 billion light-years, gravitational waves will be unleashed, which will then reach here on Earth and make us change the length of a four-kilometer-long laser interferometer. thousandth of a proton radius, so come on, really, so exactly, such absurd objects from the edge of recognizable reality cause us in a laser interferometer a change in length of one thousandth of a proton radius, so the wider is with us at 10 and -18 meters, that's Loco, that means these individual parts are there, really, very, very well, to tie them together and maybe also at this point it should be mentioned maybe also to point out one and again that physics is already a science of limitations, that is, of limits Energy conservation that tells you that energy can be generated it can only be transformed becomes an important recurring argument because in many talk shows in the future there will be someone show some crazy ideas like that with a stop sign.
By the way, I would urgently suggest that in the meantime, someone should stand on every talk show with a stop sign behind him Attention energy conservation before again Some crazy and crazy ideas are told by some as well as others that's it just the fact that physics as the science of the fundamental limits of existence has to interfere with the big questions of our time and always be the voice of reason does not follow arbitrarily like many other economic sciences we are talking about on the eternal growth maybe because physics is the calming voice the wise one that tells us to carry on so miserably that would be the task would be the task but there are many others so certainly one of the Biggest Stories yet to be revealed.
What is covered is the question of the origin of life, that is, that it is no longer a purely physical matter, of course, life is not about what should live and physics can deal with living things in biophysics, but it actually deals with the processes in the rooms. However, the original question is one of those cardinal ones of those quintessential key questions, how does dead matter become in all of physics, so to speak, what does that dead matter look like? So the question is, on the one hand, how did life come about? in the first place and, on the other hand, how life survives, that is, how order becomes order and order becomes important living beings are not a chaotic system, they have to take into account very important fundamental physical laws of nature has to give off waste, for example it has to accumulate and decompose it has to create a dynamic balance in itself and this question is, for example, one of those classic interdisciplinary lung questions that have not been clarified at all there are a number of approaches and the natural sciences are gradually getting closer and more and more tell each other what they are currently working on and there are special areas of research on the question of the origin of life and that is where biologists, biologists, chemists and physicists sit, and physicists together with computer specialists, try to solve this question together and the book that really sometimes in quotes, at least something from e So, it explains how life arose on earth that has yet to be written. so each chapter would be a further investigation story on its own
