Fundamentals of Physics I About the Course This course provides a thorough introduction to the principles and methods of physics for students who have good preparation in physics and mathematics. Emphasis is placed on problem solving and quantitative reasoning. This course covers Newtonian mechanics, special relativity, gravitation, thermodynamics, and waves. Happiness Takes (A Little) Magic There’s a whole laundry list of disclaimers attached to it, but my pal (and Pulitzer winner) Matt Richtel wrote about a Stanford research report suggesting that spending considerable amounts of time on multimedia/technology can make us unhappy. In his words: “The answer, in the peer-reviewed study of the online habits of girls aged 8 to 12, finds that those who say they spend considerable amounts of time using multimedia describe themselves in ways that suggest they are less happy and less socially comfortable than peers who say they spend less time on screens.” I owe my livelihood to technology and I love the raw capability it offers us as a tool, but I fear it a bit more than most people do. It’s a tool, but it’s not quite a hammer, because a hammer doesn’t seduce you into sitting around lonely in your underwear for 6 hours at a stretch clicking on youtube videos and refreshing Twitter.

Top 10 Traits Of Highly Successful People Rating: 8.2/10 (185 votes cast) We have all read about people who are successful briefly. They win a gold medal, make a fortune, or star in one great movie and then disappear. Pale Blue Dot Seen from about 6 billion kilometers (3.7 billion miles, 40 astronomical units), Earth appears as a tiny dot (the blueish-white speck approximately halfway down the brown band to the right) within the darkness of deep space.[1] Background[edit] The Voyager 1 spacecraft is a 722-kilogram (1,592 lb) robotic American space probe launched by NASA on September 5, 1977,[3] to study the outer solar system[4] and eventually interstellar space.[5] Operating for 36 years, 7 months and 8 days as of today (15 April 2014), the spacecraft receives routine commands and transmits data back to the Deep Space Network.

2009 January 27 - The Milky Way Over Mauna Kea Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. 2009 January 27 Topic 12: Electromagnetic Induction Induced EMF: Faraday and Lenz's Laws Induced EMF is the phenomenon of generating electricity from movement in a magnetic field. Task: Use the apparatus set up for you to make as many observations as you can. Conclusion: When a conductor moves with respect to a magnetic field (or visa versa) an electric current is induced. Meet The Author Of “Robots Will Steal Your Job, But That’s OK” Federico Pistono knows automation threatens jobs. To deal with it, he thinks we need to change our economic philosophies. Growth is a good thing, right? It’s the buzzword on seemingly every politician’s lips, the answer to our economic woes.

Scales and emotions See also a post about making chords from scales. So maybe you want to write a song or an instrumental in a particular mood or style, and you’re feeling overwhelmed by all the scales. Here’s a handy guide to the commonly used scales in Western pop, rock, jazz, blues and so on. Click each image to play the scale right in your browser with the aQWERTYon. These scales have a major third (E in the key of C), which makes them feel happy or bright. Major scale

Alternating Current - IB Physics Stuff 11.3.1 Describe the e.m.f. induced in a coil rotating within a uniform magnetic field. 11.3.2 Explain the operation of a basic alternating current (ac) generator. In both cases above the voltage is not constant, the voltage is dependent on the angle of the coil.

Sony Nextep Computer Concept for 2020 by Hiromi Kiriki In 2020 We Can Wear Sony Computers On Our Wrist Our present need for internet connectivity is so profound that secondary devices like the Nextep Computer are bound to happen. Developed to be worn as a bracelet, this computer concept is constructed out of a flexible OLED touchscreen. Earmarked for the year 2020, features like a holographic projector (for screen), pull-out extra keyboard panels and social networking compatibility, make the concept plausible. Ten years from now is not too far away, so how many of you think we’d be buying such gadgets? Designer: Hiromi Kiriki Fairyland May 14, 2010 A happy Home Tour Friday to you! Before we begin today, I need you to SIT DOWN and take several deep breaths. Because this is incredible.

84 Million Stars and Counting eso1242 — Photo Release VISTA creates largest ever catalogue of centre of our galaxy 24 October 2012 12.2 Alternating Current 12.2.1 Describe the emf induced in a coil rotating within a uniform magnetic field. As the handle is turned, AB moves up through the field. As it cuts the field a current will be induced. Using Fleming's right hand rule --> direction of current is from A to B. Direction of motion of the right hand side (CD) is opposite so current is opposite.
