VoltAlert lamp experiment
Here I demonstrate a false alarm. The VoltAlert seems to indicate that the base of the lamp is hot. Moving my hand near the base stops the sensor from triggering.

Electromotive force (EMF) introduction: Definition, batteries, Faraday's Law
zhlédnutí 6KPřed 7 lety
This video gives a primer on the electromotive force (EMF). EMF is a very important concept in electromagnetism, but can be confusing. This video attempts to define and discuss EMF in the clearest possible terms. It then discusses EMF in connection with batteries and Faraday's Law.

Simulating an analog phase locked loop

In this introductory video tutorial I simulate a phase locked loop (PLL) using NI AWR Visual System Simulator (VSS). The goal of these "virtual experiments" on PLLs is to explore some basic design trade-offs and properties of PLLs. I created this video to help people learn how how PLLs operate, and hope that this video will help compliment the mathematical explanation of PLLs with dynamic simul...

    I really do not know whether I can make a valid argument: One person is happy to accept the observable world as it is seen for the moment. The other delves into details and travels deep, to know how such miniscule details can proceed to build up a world, as the former sees. The common platform is the mind of each dictated by their individual egos. If each questions as to whence the ego arose from, the ego vanishes and a strange void rises. I believe that seeing that is seeing Reality . The seer is the self and is a part of that reality. Phew, I have said what I started to, hope it makes sense to the reader.

    If all individuals would be given the chance to reach their full potential, could you imagine where we - as humans - would be by now? As a woman, I know there’re so many inadequate individuals and circumstances that affect my development. Reaching our full potential is most of the time a question of where one is born, her family, her neighborhood, her teachers, her genes, her supportive or not networks, etc. Good luck to you old confident and assuming folks!

    I don't think a lot about brushing teeth, but I had changed the way of using toothbrush and toothpaste, I only brush my teeth when there are left over food stuck in them which I can't get rid of, and I use toothpaste to clean the brush after I'd done brushing my teeth, instead of putting it on the brush before brushing

    Feynman was right on the teeth brushing once again. The problem with modern teeth problem is more related to the diet. Carnivor diet people noticed their mouth and teeth are in good shape just like dogs that eat raw diet. The sugar coating in mouth coming from plant and sugar eating need tooth brushing and it still doesnt cure the degeneration of morden tooth decay. The diet is more of the causal variable.

    Science seems to be every bit the ritual that witchcraft used to be. It's called "scientism." The belief that science can, and should, be applied to everything. Unfortunately, the problems we face now are inner problems of values and joy and empathies. Of our utter separation from monumental natural forces far larger than ourselves, and our inability to recognize that. In fact, science has reinforced the same mechanized view that has allowed us to euthanize the planet and our own communities. We are morally adrift and no science can reverse that course.

    The waves in the lake hitting the "shore"( what's the word) just when he says "waves" was just perfect. To use scientific discoveries to be able to live to experience a moment like that is more valuable a reward than honours, prizes or a membership at the club for people who put things on top of another. Or something.

    Shameful that here we have Feynman, a wildly competent and popular and novel thinker, but yet despite his very easy to understand explanations of why taking novel approaches to learning about things to gain the knowledge of them falls largely flat on academia today. Followers, poor educators, expensive so called education that teaches the names of things instead of teaching the concept of taking a novel approach to discovering how and why things work.

    To say, that "his father was a clothing salesman" tells no more than saying "his father was 180 cm tall". His father created Richard by teaching him all kinds of cognitive skills. Most probably his father would also be a great scientist himself, should his life took different route. Richard was in a sense programmed to be great scientist and large part of credit should go to his father, who is rarely mentioned.

    • @alexandercummins
      @alexandercummins Před 9 měsíci

      "his father was a clothing salesmen" tells me Richard Feynman is from a blue collar background, his excellence in physics was something he developed himself because he wasn't from a scientific background. No one names the father are you serious! what has the father got to do with it.

    @1:38 "Testing creative ability" via recognizing problems and developing solutions to science that he was not yet exposed to yet, then verifying if he was correct via reviewing the existing science/math. @5:16 "to know what you know, and dont know." @6:00 "There's a way of looking at something anew, as if its something you never saw before for the first time. And asking questions about it as if you were different." This is how analyze for the fundamentals of something. To walk through the analytic process as if it's the first time seeing it and trying to understand the fundamentals of something from the ground up. Its a recreation of the model of something through your observable understanding of it. @6:56 "Maxwell put the equations together with the Faraday he formulated the equations mathematically with some model in his head and Dirac got his answer by just writing and guessing an equation and other people got their answers like in relativity got the idea by looking at principles of symmetry, Heisenberg got is quantum mechanics by thinking only about things you can measure." These have all been tried and now we're stuck so we have to use different methods than we used before because they've all been tried, and now we're stuck." Look to question the physical world with enthusiasm and curiosity in order to create scientific discovery.

    Only enlightened mind I have seen on screen. Just no negativity, pouring bliss into each moment out of sheer joy for knowledge. Knowledge often suffers from arrogance, NDT is an example, but Feynman cut through that to the other side. He is contended with what he has done, free of need, becoming a visual manifestation of the true meaning of success and human experience. I wish more people learn from him and get inspired.
