Flash » Magnetism Related: Physics Fun Wednesday September 14, 2005 Today was the first class of the new semester. And this year, again, is my turn to teach String Theory. This year I decided to give a slightly extended version of my usual introductory lecture, explaining why one might want to study quantum gravity and, if so, why String Theory is the only plausible vehicle for studying it. Related Quantum Gravity, Strings and M-Branes Tuesday September 13, 2005 A new twist on power walking "In an unprecedented breakthrough in the development of portable and renewable human-driven energy sources, an MBL (Marine Biological Laboratory) biomechanics expert who studies how muscle moves skeletons in fish and frogs has invented a backpack that gives new meaning to the term power walking. In a paper published in the September 9 issue of Science, Lawrence C. Rome, a University of Pennsylvania biology professor who spends his summers conducting research at the MBL, and three colleagues describe the mechanics of, and physics behind, the Suspended-load Backpack, a piece of gear that will one day enable field scientists, hikers, explorers, soldiers, and disaster workers to convert mechanical energy generated by walking with a heavy load on their backs into electricity.

49. Philosophical Foundations Of Physics Positivist view of physics, which had influenced the Copenhagen Interpretation of the Quantum mechanics (CI). http://www.marxists.org/reference/subject/philosophy/works/ge/carnap.htm

Rudolph Carnap (1966) Philosophical Foundations of Physics Chapter 23: Theories and Nonobservables Source Philosophical Foundations of Physics (1966) publ. Basic Books Inc. Chapters 23 to 26 reproduced here. ONE OF THE most important distinctions between two types of laws in science is the distinction between what may be called (there is no generally accepted terminology for them) empirical laws and theoretical laws. Empirical laws are laws that can be confirmed directly by empirical observations. The term "observable" is often used for any phenomenon that can be directly observed, so it can be said that empirical laws are laws about observable. A philosopher might object that the intensity of an electric current is not really observed. Only a pointer position was observed. An ammeter was attached to the circuit and it was noted that the pointer pointed to a mark labelled 5.3. Certainly the current's intensity was not observed. It was inferred from what was observed. The physicist would reply that this was true enough, but the inference was not very complicated. The procedure of measurement is so simple, so well established, that it could not be doubted that the ammeter would give an accurate measurement of current intensity. Therefore, it is included among what are called observables. Empirical laws, in my terminology, are laws containing terms either directly observable by the senses or measurable by relatively simple techniques. Sometimes such laws are called empirical generalisations, as a reminder that they have been obtained by generalising results found by observations and measurements. They include not only simple qualitative laws (such as, "All ravens are black") but also quantitative laws that arise from simple measurements. The laws relating pressure, volume, and temperature of gases are of this type. Ohm's law, connecting the electric potential difference, resistance, and intensity of current, is another familiar example. The scientist makes repeated measurements, finds certain regularities, and expresses them in a law. These are the empirical laws. As indicated in earlier chapters, they are used for explaining observed facts and for predicting future observable events.

Q-Ray bracelet Our Newsletter Subscribe Unsubscribe Voting Poll Science books you read a month Featured Book Physics Tip Blackbody is a surface that absorbs all radiant energy falling on it. The term arises because incident visible light will be absorbed rather than reflected, and therefore the surface will appear black. The concept of such a perfect absorber of energy is extremely useful in the study of radiation phenomena, and the description of the radiation from a blackbody is given by Planck's curve. The best practical blackbody is a small hole in a box with a blackened interior, because practically none of the radiation entering such a hole could escape again, and it would be absorbed inside. A surface covered with lampblack will absorb about 97 percent of the incident light and, for most purposes, can be considered a blackbody. Polished metal surfaces, on the other hand, absorb only about 6 percent of the incident radiation, reflecting the rest. Physics Quote "The next question was - what makes planets go around the sun? At the time of Kepler some people answered this problem by saying that there were angels behind them beating their wings and pushing the planets around an
