Mechanical resonance. Graph showing mechanical resonance in a mechanical oscillatory system Mechanical resonance is the tendency of a mechanical system to respond at greater amplitude when the frequency of its oscillations matches the system's natural frequency of vibration (its resonance frequency or resonant frequency) than it does at other frequencies. It may cause violent swaying motions and even catastrophic failure in improperly constructed structures including bridges, buildings and airplanes—a phenomenon known as resonance disaster.
Avoiding resonance disasters is a major concern in every building, tower and bridge construction project. The Taipei 101 building relies on a 660-ton pendulum — a tuned mass damper — to modify the response at resonance. Furthermore, the structure is designed to resonate at a frequency which does not typically occur. Buildings in seismic zones are often constructed to take into account the oscillating frequencies of expected ground motion. Description[edit] Examples[edit] A Few Magnet Motors. “Although originally suggested by Nikola Tesla in 1905, only a few permanent magnet motors-generators have been designed, that is, magnet motors where the power comes from the magnets, not an external, exaustable supply of electricity.” “Engineers of Hitachi Magnetics Corp. of California have stated that a motor-generator run solely by magnets is feasible and logical but the politics of the matter make it impossible for them to pursue developing a magnet motor or any device that would compete with the energy cartels.”
“Electric power is everywhere present in unlimited quantities and can drive the world’s machinery without the need for coal, oil, or gas.” - Nikola Tesla Today scientists say the universe is 60% “Radient/Dark” energy. (see our pages on “Tesla, Radiant Energy,1,2,3″) Writing on June 10th, 1902 to his friend Robert U.
Other U.S. patents have been filed – see Ammann, Hendershot, Hubbard, and others, however, only Tesla understood the Physics involved. C. Ed Gray’s R. Today: 2. Code of Conduct. How can parts of Canada be" For more than 40 years, scientists have tried to figure out what's causing large parts of Canada, particularly the Hudson Bay region, to be "missing" gravity. In other words, gravity in the Hudson Bay area and surrounding regions is lower than it is in other parts of the world, a phenomenon first identified in the 1960s when the Earth's global gravity fields were being charted.
Two theories have been proposed to account for this anomaly. But before we go over them, it's important to first consider what creates gravity. At a basic level, gravity is proportional to mass. So when the mass of an area is somehow made smaller, gravity is made smaller. One theory centers on a process known as convection occurring in the Earth's mantle. A new theory to account for the Hudson Bay area's missing gravity concerns the Laurentide Ice Sheet, which covered much of present-day Canada and the northern United States. So which theory is correct? Startup Advice: How Entrepeneurs Gain Credibility. While talking with young founders in Europe and the US over the last couple months, I have been asked the same question repeatedly -- how can an entrepreneur just starting out gain the necessary credibility to attract capital? It is an important question because, at its heart, a startup investment is an investment in the entrepreneur.
And the earlier stage the investment, the more so this is true. We all know the allure of the elusive "serial entrepreneur" -- the rare breed who has done it before (successfully) and will not fall victim to the same business pitfalls (he'll have to discover new ones). I have backed serial entrepreneurs before and will continue to back them. So how does an entrepreneur with little or no track record gain credibility?
When it comes to borrowed credibility, there is perhaps no more important act than the initial introduction you are given to an investor. The other way first time entrepreneurs gain credibility is to earn it. The Community for Data Management, Business Intelligence... Smart People Believe Weird Things: Scientific American. Simple Ideas That Are Borderline Genius Part 8. Dissecting an Episode of MythBusters. MythBusters is an excellent TV show on Discovery Channel, in which Adam, Jamie, Kari, Tory, and Grant test popular myths. That show, like so many other shows, is designed for a TV time-slot. It has to be a certain length.
There has to be a certain number of breaks, at certain times etc. But most people probably do not realize just the tactics that go into making an episode. So just for fun, let us dissect a show, and see what we can learn from it. One hour time-slot, once per week First, let us look at how much time MythBusters spend on the actual show itself vs. all the other things. They spend 4% of the time talking about what is "coming up next," 2% of time showing the MythBuster logo, and 6% repeating something they have already said - e.g. when returning from a commercial break. All of that is just filler content. Then they spend 33% of the time talking about the first myth, 17% on second myth, and only 11% on the third myth (only 6 and a half minute).
