Elementary Concepts in Statistics In this introduction, we will briefly discuss those elementary statistical concepts that provide the necessary foundations for more specialized expertise in any area of statistical data analysis. The selected topics illustrate the basic assumptions of most statistical methods and/or have been demonstrated in research to be necessary components of our general understanding of the "quantitative nature" of reality (Nisbett, et al., 1987). We will focus mostly on the functional aspects of the concepts discussed and the presentation will be very short. Tesla - Master of Lightning: A Weapon to End War Tesla inherited from his father a deep hatred of war. Throughout his life, he sought a technological way to end warfare. He thought that war could be converted into, "a mere spectacle of machines." In 1931 Tesla announced to reporters at a press conference that he was on the verge of discovering an entirely new source of energy. Asked to explain the nature of the power, he replied, "The idea first came upon me as a tremendous shock...
Nuclear Weapons - basic technology concepts [UNC] A few words about nuclear weapons technology.. Fission weapons Nuclear weapons exploit two principle physical, or more specifically nuclear, properties of certain substances: fission and fusion. Fission is possible in a number of heavy elements, but in weapons it is principally confined to what is termed slow neutron fission in just two particular isotopes: 235U and 239Pu. These are termed fissile, and are the source of energy in atomic weapons. Cranial Nerves Can't remember the names of the cranial nerves? Here is a handy-dandy mnemonic for you: On Old Olympus Towering Top AFamous Vocal German Viewed Some Hops. The bold letters stand for: olfactory, optic, oculomotor, trochlear, trigeminal, abducens, facial, vestibulocochlear, glossopharyngeal, vagus, spinal accessory, hypoglossal.
How Time Dilation Makes Sense previous home next PDF Michael Fowler, UVa Physics, 12/1/07 “Moving Clocks Run Slow” plus “Moving Clocks Lose Synchronization” plus “Length Contraction” leads to consistency! The object of this exercise is to show explicitly how it is possible for two observers in inertial frames moving relative to each other at a relativistic speed to each see the other’s clocks as running slow and as being unsynchronized, and yet if they both look at the same clock at the same time from the same place (which may be far from the clock), they will agree on what time it shows!

How to Draw Celtic Knotwork The old method These instructions can be followed with pencil and paper or using any computer based drawing or drafting program. I have used Corel Draw, Adobe Illustrator, and AutoDesk AutoCad for various projects, but my favorite is Corel Draw. Is the Universe a Holographic Reality? - Global One TV The Universe as a Hologram by Michael Talbot Does Objective Reality Exist, or is the Universe a Phantasm? In 1982 a remarkable event took place. At the University of Paris a research team led by physicist Alain Aspect performed what may turn out to be one of the most important experiments of the 20th century. You did not hear about it on the evening news. In fact, unless you are in the habit of reading scientific journals you probably have never even heard Aspect's name, though there are some who believe his discovery may change the face of science.
Hammack Home This book is an introduction to the standard methods of proving mathematical theorems. It has been approved by the American Institute of Mathematics' Open Textbook Initiative. Also see the Mathematical Association of America Math DL review (of the 1st edition), and the Amazon reviews. The second edition is identical to the first edition, except some mistakes have been corrected, new exercises have been added, and Chapter 13 has been extended. (The Cantor-Bernstein-Schröeder theorem has been added.) The two editions can be used interchangeably, except for the last few pages of Chapter 13.
Career Options for Physics Majors Do Anything. Do It All. Do Physics. Dr. Nate Bachman has the best of both worlds. He gets to put hardcore physics principles into practice when developing tools that must work effectively for the oil industry. Quadratic Equations: Quadratic Formula Consider the general quadratic equation with . A Brief History of Time - Stephen W. Hawking Our Picture of the Universe Any physical theory is always provisional, in the sense that it is only a hypothesis: you can never prove it. No matter how many times the results of experiments agree with some theory, you can never be sure that the next time the result will not contradict the theory. On the other hand, you can disprove a theory by finding even a single observation that disagrees with the predictions of the theory... Each time new experiments are observed to agree with the predictions the theory survives, and our confidence in it is increased; but if ever a new observation is found to disagree, we have to abandon or modify the theory. 11 Today scientists describe the universe in terms of two basic partial theories - the general theory of relativity and quantum mechanics...
Singularity Theory May Explain Fermi Paradox The Drake equation demonstrates that due to the vast scope of our universe, it is highly unlikely that there is not intelligent life other than us. The Fermi paradox ponders why (considering the results from the Drake equation) we have not yet detected any other intelligent life. Singularity theory anticipates a point in time where rapid growth in intelligence and replication create a border that is like an asymptote or singularity threshold beyond which lies an undefinable area that is not comparable to what we currently know as intelligence.
