440 or 442? Orchestra: Which does your orchestra tune to? From Daniel Stone Posted May 11, 2007 at 05:00 AM I think most orchestras in the U.S. tune to 440 but I've heard that some are starting to go up to 442. I know its a small difference but some pianos that I've played with are at 442 and its just enough to throw me off since I'm used to 440. Should I try to get used to both of them? Lots of orchestras tune to 442. When a string soloist plays with an orchestra, does the soloist ever tune a few cents sharper? I would think that would help the soloist stand out just a wee bit more, and also make him sound slightly brighter, or more cutting, than the section. Is this ever done, or even standard practice? What about with a piano soloist, where the equal-temperment is already mucking things up? >When a string soloist plays with an orchestra, does the soloist ever tune a few cents sharper? Some soloists in fact do that, and it can be heard on several CD recordings. Best,Friedrich Nathan: We knew that Mr.

Resources for You (Radiation-Emitting Products) > Microwave Oven Radiation About Microwaves Microwaves are used to detect speeding cars, to send telephone and television communications, and to treat muscle soreness. Industry uses microwaves to dry and cure plywood, to cure rubber and resins, to raise bread and doughnuts, and to cook potato chips. The Food and Drug Administration (FDA) has regulated the manufacture of microwave ovens since 1971. What is Microwave Radiation? Microwaves are a form of "electromagnetic" radiation; that is, they are waves of electrical and magnetic energy moving together through space. Microwaves have three characteristics that allow them to be used in cooking: they are reflected by metal; they pass through glass, paper, plastic, and similar materials; and they are absorbed by foods. Cooking with Microwaves Microwaves are produced inside the oven by an electron tube called a magnetron. Although heat is produced directly in the food, microwave ovens do not cook food from the "inside out." Microwave Oven Safety Standard
Pitch (music) In musical notation, the different vertical positions of notes indicate different pitches. Play top & Play bottom Pitch may be quantified as a frequency, but pitch is not a purely objective physical property; it is a subjective psychoacoustical attribute of sound. In most cases, the pitch of complex sounds such as speech and musical notes corresponds very nearly to the repetition rate of periodic or nearly-periodic sounds, or to the reciprocal of the time interval between repeating similar events in the sound waveform. The pitch of complex tones can be ambiguous, meaning that two or more different pitches can be perceived, depending upon the observer. When the actual fundamental frequency can be precisely determined through physical measurement, it may differ from the perceived pitch because of overtones, also known as upper partials, harmonic or otherwise. The relative perception of pitch can be fooled, resulting in aural illusions. Pitches are labeled using:

They apply to any "electronic product" which is defined as: any manufactured or assembled product (or component, part, or accessory of such product) which, when in operation, (i) contains or acts as part of an electronic circuit and (ii) emits (or in the absence of effective shielding or other controls would emit) electronic product radiation. "Electronic product radiation" is defined as: (A) any ionizing or non-ionizing electromagnetic or particulate radiation, or (B) any sonic, infrasonic, or ultrasonic wave, which is emitted from an electronic product as the result of the operation of an electronic circuit in such product.

The tradition and its writings date to at least the first century B.C.E., and the texts we possess were all written prior to the second century C.E. The surviving writings of the tradition, known as the Corpus Hermeticum (the "Hermetic body of writings") were lost to the Latin West after classical times, but survived in eastern Byzantine libraries. Upon a time while my mind was meditating on the things that are, my thought was raised to a great height, while the physical senses of my body were held back—just as are the senses of men who are heavy with sleep after a large meal, or from fatigue of body. -- Lance S. Translation by G. The collection of Gnostic texts found at Nag Hammadi in 1945 (known as the Nag Hammadi Library), includes a previously unknown and crucially important Hermetic document, The Discourse on the Eighth and Ninth.
Radiation Safety FDA’s Center for Devices and Radiological Health (CDRH) radiation safety programs involve enforcement of mandatory requirements in addition to partnerships and voluntary programs that promote the safe use of radiation-emitting products. The goal of these programs is to ensure that the public and professionals alike are informed of the risks posed by different types of radiation emissions and radiation-emitting products. It is also to balance the beneficial use of radiation by ensuring that each patient receives the appropriate radiation dose using the appropriate, medically necessary imaging exam at the appropriate time. These programs recognize that we all have a role in promoting radiation safety, so that: This page links to several radiation safety initiatives within FDA’s Center for Devices and Radiological Health.
The Neuroscience Of Music | Wired Science Why does music make us feel? On the one hand, music is a purely abstract art form, devoid of language or explicit ideas. The stories it tells are all subtlety and subtext. And yet, even though music says little, it still manages to touch us deep, to tickle some universal nerves. When listening to our favorite songs, our body betrays all the symptoms of emotional arousal. The pupils in our eyes dilate, our pulse and blood pressure rise, the electrical conductance of our skin is lowered, and the cerebellum, a brain region associated with bodily movement, becomes strangely active. We can now begin to understand where these feelings come from, why a mass of vibrating air hurtling through space can trigger such intense states of excitement. Because the scientists were combining methodologies (PET and fMRI) they were able to obtain an impressively precise portrait of music in the brain. The question, of course, is what all these dopamine neurons are up to.
Hermes and Hermeticism Gnosis Archive | Library | Bookstore | Index | Web Lectures | Ecclesia Gnostica | Gnostic Society by Stephan A. Hoeller There are few names to which more diverse persons and disciplines lay claim than the term "Hermetic." Who, then, was Hermes, and what may be said of the philosophy or religion that is connected with him? They say that this Hermes left his own country and traveled all over the world…; and that he tried to teach men to revere and worship one God alone, …the demiurgus and genetor [begetter] of all things; …and that he lived a very wise and pious life, occupied in intellectual contemplation…, and giving no heed to the gross things of the material world…; and that having returned to his own country, he wrote at the time many books of mystical theology and philosophy.1 Until relatively recently, no one had a clear picture of either the authorship or the context of the mysterious writings ascribed to Hermes.
