Immolation/Immersion

Clarinetist/saxophonist Dexter Payne has an interesting take on Whitney Balliett's term "the sound of surprise," which is how the well-known critic describes jazz. Payne has stated that with the more accessible forms of jazz -- which could be anything from Dixieland to bossa nova -- listeners are given a mixture of surprise and familiarity, whereas free jazz is "total surprise." And total surprise, Payne asserts, is something that only a small group of listeners are able to comprehend and get into. Some people have described free jazz as the punk rock of jazz, but in a post-Nirvana, post-Nevermind world, punk is downright mainstream -- and free jazz has remained very underground. Nonetheless, free jazz's true believers carry on fearlessly, which is a good thing because for those who do comprehend an album like Immolation/Immersion, the rewards are certainly there. Although not groundbreaking by mid-2000s standards, this 2005 date is an enjoyable demonstration of what electric guitarist Nels Cline, alto saxman Wally Shoup, and drummer Chris Corsano have to offer in a free jazz environment. Some avant-garde jazz favors an inside/outside approach, but this trio is outside all the way -- and the outside serves Cline, Shoup, and Corsano well whether they're getting into dense, chaotic atonality or going for something that is reflective and spacy in an AACM-ish way. Even at its most chaotic, Immolation/Immersion isn't as extreme as the blistering work of Charles Gayle or post-1965 John Coltrane; nonetheless, this is very abstract, cerebral, uncompromising music that must be accepted on its own radical terms. Immolation/Immersion won't go down in history as a disc that points avant-garde jazz in any new directions, but it's a worthwhile effort that free jazz diehards should be aware of. ~ Alex Henderson, Rovi Performers: Chris Corsano - Drums; Nels Cline - Guitar (Electric); Wally Shoup - Sax (Alto)

Total Immersion - Demo 2007

What language(s) other than your native one are you fluent in and how did you become fluent?


Hi, I was wondering what languages others were fluent in and how they achieved fluency. What worked best for you? Was it a program like Rosetta Stone, total immersion into the language, classroom study, self study, etc.? I'd also appreciate any tips on learning languages
Thanks!!
Cass

I became Fluent in English through immersion Ie being put in a situation where English is aroudn you and you just pick it up plus English lessons in School.

I became fluent in Afrikaans again through Immersion spending time in pretoria and learning it at home and through my family members

I became fluent in cornish after listening to news podcasts and so on and reading material in that language, as the language is very closely related to my native welsh language most of the vocab came straigh away.

I am currently learning german and spanish not fluent but i can speak quite abit again partially through imemrsion.
In my opinion Immersion is the easiest way,.

Which is better Fastskin II by speedo or the Tracer Light by TYR ?


im looking for a legskin but idk which one to get .. i swim the 100 back and the 100 fly .. i dont want a full bodysuit but idk which legskin is the best and i also dont know if the fs pro is too much

Speedo, most def. It is probably the best brand you can buy, and it is more durable. I have been extremely happy with all my speedo's, and TYR is a little uncomfy. Plus, speedo glides with you, and doesn't have as much lag. I think i have seen guys with the Fastskin around our swim meets, and it looks way more comfortable. Good luck :)

If Cartoon Characters Wear Watches

When we were kids, most of us have at least one or two favorite cartoon or comic book character.  We liked these cartoon characters so much that our pencil cases, bags, lunch boxes, and shirts are printed with their images.  Because we see these cartoon characters almost everyday, we can tell if there is something different about the way our favorite characters look.  Their change in poses and costumes can be easily detected by an observant kid's mind.  With the many cartoon characters introduced since the invention of the comic book, can we remember if any of our favorite cartoon characters wore a watch?

Probably, most of us cannot recall a time when our favorite cartoon characters have worn a watch.  Why would they anyway?  Most of the cartoon characters are animated animals and although these animals can speak and interact with one another, there isn't much need for them to wear a watch.  Watches are not as important to the animal kingdom as they are to ours.  However, let us take a look at how our favorite cartoon characters would have chosen a watch if given a chance to wear one.

1.  Spongebob

The energetic character of Spongebob Squarepants would have chosen the Flik Flak "Dirty Jumps" as his watch.  This watch comes in yellow, which certainly matches Spongebob's color and optimistic personality.  The happy-go-lucky yet naïve Spongebob will also enjoy the added features of the watch.  The Flik Flak "Dirty Jumps" is shock and water- resistant, and machine washable.  This is perfect for someone like Spongebob who is inquisitive, curious, and adventurous.

2.  Betty Boop

The sexy Betty Boop will need a watch to reflect her appeal.  The Citizen Silhouette ladies' watch will match Betty Boop's fitted dresses, high heels, and garter belt.  The watch also has a crystal-encrusted bracelet and a mother of pearl face that makes it very stylish for a woman as classy and sexy as Betty Boop.

3.  Bubbles of Powerpuff Girls

This innocent Powerpuff Girl, with her blue signature color, will find a match in the blue Flik Flak "Fior di Farfalla."  Bubbles' bubbly, naïve, playful, cute, and gentle personality is also reflected in the strap that has flower and butterfly designs.

4.  Angelica Pickles of the Rugrats

This bully needs a watch with an attitude.  The Flik Flak "Pink Flak" is the choice for girls who would like to the envy of other girls.  This watch will be a sign of Angelica's affluent upbringing that has led her to bullying other babies.  The color also matches her expensive and colorful outfits.

5.  Spiderman (Peter Parker)

Spiderman is one of the most favorite cartoon characters and superheroes of all time.  A superhero needs a watch that can make his task of rescuing people a lot easier.  The Casio "G Shock" G1000-1A is perfect for men like Peter Parker who tackle a lot of things during the day.  As a photographer, he always has to be on the go to catch the perfect and rare shot.  As Spiderman, he should have a durable watch that can resist up to a hundred meters of water.  Its alarm clock will help him stay on schedule and the G Shock's luminous hands will help him see the time even while in the dark.

6.  George of the Jungle

For someone who lives in the jungle, watches aren't very useful.  But if George really needs something for telling the time, the M.H. Bertucci B-1T Titanium is a good choice.  He needs a watch that is durable enough to withstand jungle activities.  The M.H. Bertucci is also shock and water-resistant, which makes it great for adventurous George.

About the Author

Joaquin Rivera is an fan of cartoons and watches. He gives advice to people on what kind of watch they should buy.

I see a lot of light tracers and dots everywhere i look 24/7, does anybody know what this might be?


almost as if you were to press on your eye lids and see swirling colors and patters, i see that constantly and im not quite sure why, and its a little distracting. just wondering if anybody has had that same experience or knows what it may be.

My 19 year old son has 'squiggles' and 'dots' that he finds very annoying. Our optometrist said they are harmless and there is nothing he can do for them. See your own eye doctor just to make sure yours aren't something serious. Retinal diseases should be ruled out.

Importance of Being Isotopes of Hydrogen

Only three isotopes are considered significant enough to have names of their own, as opposed to being named after a parent atom (for example, carbon-12 and uranium-238). These are protium, deuterium, and tritium, all three isotopes of hydrogen. Protium, or 1H, is hydrogen in its most basic form—one proton, no neutrons—and the name "protium" is only applied when necessary to distinguish it from the other two isotopes. Therefore it is proper to focus primarily on the two others. Deuterium, designated as 2H, is a stable isotope, whereas tritium 3H is radioactive. Both, in fact, have chemical symbols, D and T respectively, as if they were elements on the periodic table. What makes these two so special? They are,  "the products of a good home as their parent atom is the most basic and plentiful element in the universe. Indeed, the vast majority of the universe is hydrogen, along with helium, which is formed by the fusion of hydrogen atoms. If all atoms were numbers, then hydrogen would be 1; but of course, this is more than a metaphor, since its atomic number is indeed 1.

Ordinary hydrogen or protium, as noted, consists of a single proton and a single electron, the simplest possible atomic form possible. Its simplicity has made it a model for understanding the atom, and therefore when physicists discovered the existence of two hydrogen atoms that were just a bit more complex, they were intrigued. Just as hydrogen represented the standard against which atoms could be measured, scientists reasoned, deuterium and tritium could offer valuable information regarding stable and unstable isotopes respectively. Furthermore, the pronounced tendency of hydrogen to bond with other substances that almost never appears by itself on Earth presented endless opportunities for study regarding hydrogen isotopes in association with other elements.

Deuterium is sometimes called "heavy hydrogen," and its nucleus, with one proton and one neutron, is called a deuteron. It was first isolated in 1931 by American chemist Harold Clayton Urey (1893-1981), who was awarded the 1934 Nobel Prize in Chemistry for his discovery. Serving at that time as a professor of chemistry at Columbia University in New York City, Urey started with the assumption that any hydrogen isotopes other than protium must exist in very minute quantities. This assumption, in turn, followed from an awareness that hydrogen's average atomic mass, measured in atomic mass units, was only slightly higher than 1. There must be, as Urey correctly reasoned, a very small quantity of "heavy hydrogen" on Earth. To separate deuterium, Urey collected a relatively large sample of liquid hydrogen: 4.2 quarts (4 l). Then he allowed the liquid to evaporate very slowly, predicting that the more abundant protium would evaporate more quickly than the isotope whose existence he had hypothesized. After all but 0.034 oz (1 ml) of the sample had evaporated, he submitted the remainder to a form of analysis called spectroscopy, adding a burst of energy to the atoms and then analyzing the light spectrum they emitted for evidence of differing varieties of atom.

Deuterium, with an atomic mass of 2.014102 amu, is almost exactly twice as heavy as protium, which has an atomic mass of 1.007825. Its melting point, or the temperature at which it changes from a solid to a liquid ?426°F (?254°C), is much higher than for protium, which melts at ?434°F (?259°C). The same relationship holds for its boiling point, or the temperature at which it changes from a liquid to its normal state on Earth, as a gas: ?417°F (?249°C), as compared to ?423°F (?253°C) for protium. Deuterium is also much, much less plentiful than protium which represents 99.985% of all the hydrogen that occurs naturally, meaning that deuterium accounts for just 0.015%. Often, deuterium is applied as a tracer, an atom or group of atoms whose participation in a chemical, physical, or biological reaction can be easily observed. Radioisotopes are most often used as tracers, precisely because of their radioactive emissions; deuterium, on the other hand, is effective due to its almost 2:1 mass ratio in comparison to protium. In addition, it bonds with other atoms in a fashion slightly different from that of protium, and this contrast makes its presence easier to trace. Its higher boiling and melting points mean that when deuterium is combined with oxygen to form "heavy water" (D2O), the water likewise has higher boiling and melting points than ordinary water. Heavy water is often used in nuclear fission reactors to slow down the fission process, or the splitting of atoms.

Deuterium is also applied in a type of nuclear reaction much more powerful than fission, fusion or the joining of atomic nuclei. The Sun produces energy by fusion, a thermonuclear reaction that takes places at temperatures of many millions of degrees Celsius. In solar fusion, it appears that two protium nuclei join to form a single deuteron. During the period shortly after World War II, physicists developed a means of duplicating the thermonuclear fusion process. The result was the hydrogen bomb, more properly called a fusion bomb, whose detonating device was a compound of lithium and deuterium called lithium deuteride. Vastly more powerful than the "atomic" (that is, fission) bombs dropped by the United States over Japan in 1945, the hydrogen bomb greatly increased the threat of worldwide nuclear annihilation in the postwar years. Yet the power that could destroy the world also has the potential to provide safe, abundant fusion energy from power plants, a dream that as yet remains unrealized. Among the approaches being attempted by physicists studying nuclear fusion is a process in which two deuterons are fused. The result is a triton, the nucleus of tritium, along with a single proton. The triton and deuteron would then be fused to create a helium nucleus, with a resulting release of vast amounts of energy.

Whereas deuterium has a single neutron, tritium, as its mass number of 3 indicates, has two. And just as deuterium has approximately twice the mass of protium, tritium has about three times its mass, 3.016 amu. As is expected, the thermal properties of tritium are different from those of protium. Again, the melting and boiling points are higher: thus tritium heavy water (T2O) melts at 40°F (4.5°C), as compared with 32°F (0°C) for H2O. Because it is radioactive, tritium is often described in terms of half-life, the length of time it takes for a substance to diminish to one-half its initial amount. The half-life of tritium is 12.26 years. As it decays, its nucleus emits a low-energy beta particle which results in the creation of the helium-3 isotope. Due to the low energy levels involved, the radioactive decay of tritium poses little danger to humans. Like deuterium, tritium is applied in nuclear fusion, though due to its scarcity, it is usually combined with deuterium. Furthermore, tritium decay requires that hydrogen bombs containing the radioisotope be recharged periodically. Also, like deuterium, tritium is an effective tracer. Sometimes it is released in small quantities into groundwater as a means of monitoring subterranean water flow. It is also used as a tracer in biochemical processes.

As noted in the discussion of deuterium, tritium can only be separated from protium due to the differences in mass. The chemical properties of isotopes with the same parent element make them otherwise indistinguishable, and hence purely chemical means cannot be used to separate them. Physicists working on the Manhattan Project, the U.S. effort to develop atomic weaponry during World War II, were faced with the need to separate 235U from 238U. Uranium-238 is far more abundant, but what they wanted was the uranium-235, highly fissionable and thus useful in the processes they were attempting. Their solution was to allow a gaseous uranium compound to diffuse, or separate, the uranium through porous barriers. Because uranium-238 was heavier, it tended to move more slowly through the barriers, much like grains of rice getting caught in a sifter. Another means of separating isotopes is by mass spectrometry.
