Why a swaying bridge collapses with a high wind, and why a wine glass shatters with a higher octave. The new course took the opposite tack, of trying to recreate the historical excitement of the original discovery. The sheer difficulty of the problem he faced and the elegance of the method he applied to solve it are abundantly clear. I cannot imagine a better way to present this magnificent discovery, which can easily appear so trivial. A changing magnetic field creates an electric current: By finding the missing conceptual piece in the mathematics of electricity and magnetism, Understanding light as a wave makes sense of, If light is a wave, what is waving? The music and mathematics of periodic motion. An apple falls and the Moon orbits the Earth because of, A body in uniform circular motion has both constant speed and constant, Systems that are stable are at their lowest, Newton proved that an inverse-square law of gravity implies that celestial bodies move in orbits that are, The conservation of energy and angular momentum help determine how. A follow-up study found that the videos could also be helpful explaining physics to professors in other fields. [2] Computer animation was also used to portray idealizations of physical systems, like simulated billiard balls illustrating Newton's laws of motion. Einstein is motivated to perfect the central ideas of physics, resulting in a new understanding of the meaning of space and time. [35], A 2005 column in The Physics Teacher suggested The Mechanical Universe as preparatory viewing for instructors attempting to teach physics for the first time. A look at the Platonic theory of uniform circular motion. Furthering the understanding of how electric charges exert forces and do work. [50] Caltech also posted on YouTube a series of short videos made by Blinn to demonstrate the show's computer animation at SIGGRAPH conferences. A minority education program at the University of California, Berkeley employed Mechanical Universe episode segments (on LaserDisc) as part of group discussions. [28] The reviewers also found the "algebraic ballet" of computer-animated equations too fast to follow: "After a short time, one yearns for a live professor filling the blackboard with equations". [2] Many seats in the lecture hall had to be removed in order to make room for the camera track and studio lights. This page was last edited on 15 September 2020, at 13:17. Accordingly, celestial mechanics is the backbone of the subject and its climax is Newton's solution of the Kepler problem. There were 18,000 faithful core households in Dade County alone, the median age of the viewers was 18, and half were female. In 1887, an exquisitely designed measurement of the earth's motion through the ether results in the most brilliant failure in scientific history. Potential energy provides a powerful model for understanding why the world has worked the same way since the beginning of time. Hot discoveries about the behavior of gases make the connection between temperature and heat. This puzzle led to. Einstein realized that, if the speed of light is to be the same for all observers, then distances in space and durations of elapsed time must be relative. Electron waves attracted to the nucleus of an atom help account for the periodic table of the elements and ultimately lead to the search for quarks. An overview of the subject matter for the latter half of the series. [9], The series was originally planned to consist of 26 episodes. All physical phenomena of nature are explained by four forces: two nuclear forces, gravity, and electricity. The deduction of Kepler's laws from Newton's universal law of gravitation is one of the crowning achievements of Western thought. Einstein arrived at the Lorentz transformation from a deeper conceptual understanding, creating a theory full of surprises like the. Maxwell discovers that displacement current produces electromagnetic waves or light. Electromagnetic induction makes it easy to generate alternating current while transformers make it practical to distribute it over long distances. [23], Annenberg/CPB provided the funding for the production of The Mechanical Universe. A last lingering look back at mechanics to see new connections between old discoveries. Apostol, and D.L. [43][44], Like many introductory physics texts, The Mechanical Universe cites the spectacular 1940 collapse of the Tacoma Narrows Bridge as an example of resonance, using footage of the disaster in the "Resonance" episode. Franklin proposes a successful theory of the Leyden jar and invents the parallel plate capacitor. Some of Blinn's animations for The Mechanical Universe were reused in the new series, in order to illustrate applications of algebra, geometry, and trigonometry. The "nuts and bolts" of how electrical circuitry was made practical, featuring. The companion text [...] was placed on library reserve for the course but was not extensively utilized by students.[31]. Review of the mathematical operation the derivative. The discovery of elliptical orbits helps describe the motion of heavenly bodies with unprecedented accuracy. [38], In 1987, "The Lorentz Transformation" (episode 42) was awarded the sixteenth annual Japan Prize for educational television. [10][11] This was later expanded to 60 episodes, a number then cut back to the eventual total of 52 for budget and production-schedule reasons. The study of thermodynamics begins with gases. Historical scenes were often made to be generic, in order to facilitate their reuse across multiple episodes: "Young Newton strolls through an apple orchard, old Newton testily refuses a cup of tea from a servant, and so on". [9] Yorkshire Television later produced a version repackaged for the United Kingdom audience, which was released in April 1991. [2][12], The show was intended not to require previous experience with calculus. The precise orbit of a heavenly body - a planet, asteroid, or comet - is fixed by the laws of conservation of energy and angular momentum. [47][48] The reason for the addition is explained by Goodstein in the closing lecture segment of the final episode: In the first scientific revolution, disputation over the interpretation of human or divine authority was replaced by observation, by measurement, by the testing of hypotheses, all of it with the powerful help of quantitative mathematical reasoning. If the speed of light is to be the same for all observers, then the length of a meter stick, or the rate of a ticking clock, depends on who measures it. When is electricity dangerous or benign, spectacular or useful? [24] The show was one of the first twelve projects funded by the initial $90 million pledge the Annenberg Foundation gave to the Corporation for Public Broadcasting in the early 1980s. And the result of all that was the mechanical universe, a universe that inexorably worked out its destiny according to precise, predictable, mechanical laws.
