Differences in the philosophy of ideas and approaches can lead to the same discovery. Like relativity, there was an accumulation of paradoxes that we could not explain with the laws were known. His enlightened approach, wit & enthusiasm make this a memorable exposition of the scientist's craft. He points out how Isaac Newton combined an incomplete knowledge with observational results to ‘guess’ the laws of gravitation. There’s a running theme here of accumulating inconsistencies. That all of the lectures are present means that complex ideas can be developed properly and delivered over a few chapters. This post will summarise the key lessons that I took from Feynman’s lectures, focusing more on his thinking methods and reflections than on the physics itself. Documentary | TV Mini-Series (1964– ) Episode Guide. “It always turns out that the greatest discoveries abstract away from the model and the model never does any good”. Minerva Review accepts no responsibility for any claim, damage or loss as a result of material included on this website. When we get really stuck, it’s because “the methods we are using are just like the ones we have used before”. So, it helps to specify how we might be wrong, prior to the observation or experiment itself. Powerful ideas seem to contain basic principles that enable us to derive a whole basket of insights. Their text was published by the BBC in 1965 in a book by the same name. Richard Feynman (1918-88) was one of the most remarkable and gifted theoretical physicists of any generation. He described for example how the laws of gravitation and a study of Jupiter’s satellites allowed scientists to determine the speed of light. But if we hold a precondition with absolute certainty, then we can never change or update our views. For instance, when Dmitri Mendeleev arranged the elements by atomic number, electron configuration and chemical properties, the gaps in his periodic table made predictions about new elements that we’d discover in the decades ahead. And that special day will never happen again. We’re all “connecting one step to another”, “both from working at the ends and working in the middle, and in that way, we are gradually understanding this tremendous world of interconnecting hierarchies.”, “There seem to be a lot of unrelated concepts; but with a more profound understanding of the various principles, there appear deep interconnections between the concepts, each one implying others in some way.”. And for those that believe that the only theories that matter are those that agree with experiment, Feynman asks whether they’re indifferent between Mayan astronomy and our modern understanding of planetary motion. Feynman says it isn’t “sensible for the ones who specialize at one end, and the ones who specialize at the other end, to have such disregard for each other”. To Feynman, physical laws describe the rhythms and patterns that we observe in our universe. If we attack every idea with a ‘why’, we’ll soon find ourselves up against the boundaries of theory and evidence. To uncover the mystery of nature and models for mathematics, Feynman distinguishes between two schools of thought: (1) Babylonian tradition; and (2) Greek tradition. “We must always keep all the alternative ways of looking at a thing in our heads; so physicists do Babylonian mathematics, and pay but little attention to the precise reasoning from fixed axioms”. the principles of conservation). The lectures covered the following topics: 1. Often, when all the known principles and knowledge of a system are taken together, we find inconsistencies. The Character of Physical Law. He likens the process of discovery to a wonderful jigsaw puzzle. The lectures covered the following topics: Critical reception has been positive. “You have to learn the tricks; it is just a series of rules that people have found out that are very useful for such a thing.”. By contrast, the Euclidean or Greek tradition focused on a set of axioms that contain the consequences that follow. For instance, Feynman describes how the Newtonian description of gravitation lead to the derivation of the law of conservation of angular momentum. The Law of Gravitation is the principal example. The BBC recorded the lectures, and published a book under the same title the following year;[1] Cornell published the BBC's recordings online in September 2015. However, like the conservation of energy, there are principles we’ve observed to be true, as far as we know at least. In A Brief History of Time, Stephen Hawking specified some requirements: First, without too many arbitrary elements, it should describe many classes of observations. The Character of Physical Law are a series of seven lectures. The Character of Physical Law is a series of seven lectures by physicist Richard Feynman concerning the nature of the laws of physics. He thinks it’s quite the opposite. Einstein had formulated his special and general theory of relativity on the basis that objects with positive rest mass could not travel faster than the speed of light. The Newtonian description for example was eventually found to be inadequate. What Do You Care What Other People Think? The relation of mathematics and physics 3. And it often takes a subtle change or substitute to make the pieces of the puzzle work. So, Feynman tends to err towards the Babylonian tradition. Feynman says “history does not help us much” with solving the next major mystery. You’ll be all the worldlier for it. Feynman says there’s an art to guessing nature’s laws. While this model was not a description of reality, the equations that came from it were consistent with observations. Additionally, while we can disprove a theory, we can never prove it right. It could be in our guess, computation and/or comparison. “What we need is imagination, but imagination in a terrible strait-jacket”. First we guess it. These laws are often simple but universal in their description. And most of us derive some joy from understanding than calculating nature’s machinery. (1988). Richard Feynman delivered a wonderful lecture series in 1964 called The Character of Physical Law, introducing listeners to several fundamental topics in physics.From Newtonian motion to Heisenberg’s uncertainty principle, Feynman dazzles us with the beauty and peculiarities of nature along the way. “Philosophically, you like them or do not like them; and training is the only way to beat that disease… As long as physics is incomplete, and we are trying to understand the other laws, then the different possible formulations may give clues about what might happen in other circumstances”. While certain ideas are scientifically and mathematically equivalent, they can differ in philosophy and psychology. Unfortunately, the craft of natural lawmaking faces a big challenge. This applies not only to science, but to the humanities and creative arts as well. Richard Feynman delivered a wonderful lecture series in 1964 called The Character of Physical Law, introducing listeners to several fundamental topics in physics. We also exhibit a habit for organising and categorising what we know. We wouldn’t make any predictions if all the laws or theories we develop are based solely on the results we’ve observed. Actually, it is probably merely a matter of luck, but it looks as if it takes considerable skill”. The Character of Physical Law. Some observation in the future could debunk what we think we know. Furthermore, there are infinite ways to guess at something. This gives us the confidence and opportunity to make incremental progress in our quest for understanding. What is the character of our physical laws? AuthorMinerva Review / Posted on21/11/202021/11/2020. If your bias is incorrect, then an accumulation of experiments should reshape your views and beliefs. The Character of Physical Law is a series of seven lectures by physicist Richard Feynman concerning the nature of the laws of physics. Albert Einstein ‘guessed’ the general theory of relativity after thinking about the “accumulation of paradoxes” from the known laws. And if you’re making predictions that extend beyond your observable range, then there must be some uncertainty. It’s a large puzzle with many different and proliferating pieces. Available at and , Stephen Hawking. While we know today that Newton’s laws were incomplete descriptions, the conservation of angular momentum (to our knowledge) remains a valid and universal principle.
