Advertisements How important are the laws of thermodynamics? A good many times I have been present at gatherings of people who, by the standards of the traditional culture, are thought highly educated and who have with considerable gusto been expressing their incredulity at the illiteracy of scientists. Once or twice I have been provoked and have asked the company how many of them could describe the Second Law of Thermodynamics. The response was cold: Yet I was asking something which is the scientific equivalent of: Thermodynamics is not based on studying one particle at a time. This infographic describes the laws in a different — but equivalent — way. But for the sake of completeness, we include it: Thermal energy will flow from the body at a higher temperature, to the one at a lower temperature, until thermal equilibrium between the two bodies is reached.

It is science, though many times confused as being the same thing. I’ll prove my point. You know that I could never have been inside of your mysterious building out there, and I imagine you can be sure no one has told me its secrets. Yet I’ll bet that I can describe fairly accurately what is in there—not from seeing the machinery, but from knowing what must be done to oil in order to get the products you need. You want to hear?

Define “isotope” using mass number, atomic number, number of protons, neutrons and electrons. Given information about an element, find the mass and name of an isotope. Give evidence to support or dispute: “In nature, the chance of finding one isotope of an element is the same for all isotopes.”.

Why does British food have a reputation for being so bad? Because it is bad!

There was plenty of room for improvement. Before star chefs such as Oliver began making cooking fashionable, it was hard to find a restaurant in London that was open after 9pm. Tamlyn is in the second camp.

Algebra 1, High School Biology Recommended: The CLEP covers two years worth of material. Those wishing to take the CLEP will have to do significant additional study. This curriculum includes topics such as matter, atomic theory, the periodic table of the elements, bonding, chemical equations, chemical bonding, stoichiometry, gas laws, acids, bases, and salts, reaction rates, thermonuclear and nuclear chemistry, and equilibrium.

Students learn through texts, videos, online tutorials, as well as through hands-on and virtual laboratory experiments.

Hello there, I discovered your web site via Google at the same time as looking for a related matter, your website came up, it appears to be like great.

Does it require more or less effort to push a loaded wheelbarrow over hard level ground than to turn around and pull it? What about when the ground is soft? Surely the clear lens would let the light through rather than casting a shadow? At constant velocity, is this a real effect? If so, wouldn’t it be felt on any “moving” surface you walk on, such as a train or plane — or even Earth? Continued 31 January Pollution resolution If I replace my old diesel car with a less polluting new petrol one, how long will it take for the reduced pollution of the new car to outweigh the increased pollution caused by the manufacture of the new car and the disposal of the old, assuming average usage?

It seems such a waste of energy.

Walter Brown’s “Hydroplate” Flood Model Doesn’t Hold Water

The place where most laboratory ultra-high pressure work is done. Two diamond faces separated by a thin gasket in the shape of an annulus. The item to be pressurized is in fluid in the cell. When the diamond faces are pressed together, the gasket is deformed outward somewhat. The radial force on the gasket is only the cell pressure times the area of its vertical inner surface, whereas the normal force is the same pressure exerted by a diamond face times its surface area.

Consider also the most popular explanation offered for the photo right , that a concretion formed around an s-era hammer as minerals precipitated out of the surrounding limestone. From Adam until Real Science Radio , in only generations! Another paper, in the American Journal of Physical Anthropology Eugenie Scott ‘s own field on High mitochondrial mutation rates , shows that one mitochondrial DNA mutation occurs every other generation, which, as creationists point out , indicates that mtEve would have lived about generations ago.

That’s not so old! As our List of Not So Old Things this web page reveals, by a kneejerk reaction evolutionary scientists assign ages of tens or hundreds of thousands of years or at least just long enough to contradict Moses’ chronology in Genesis. However, with closer study, routinely, more and more old ages get revised downward to fit the world’s growing scientific knowledge. Consistent with this observation, the May issue of National Geographic quotes the U.

Fantasies, Falsehoods, and Fear-Mongering about Iran’s Nuclear Program “To tell deliberate lies while genuinely believing in them, to forget any fact that has become inconvenient, and then, when it becomes necessary again, to draw it back from oblivion for just so long as it is needed, to deny the existence of objective reality and all the while to take account of the reality which one denies — all this is indispensably necessary.

For nearly thirty years now, U. If these warnings are to be believed, Iran is only a few years away from unveiling a nuclear bomb Fittingly, let’s begin in An April 24, article entitled ” ‘Ayatollah’ Bomb in Production for Iran ” in United Press International referenced a Jane’s Intelligence Defense Weekly report warning that Iran was moving “very quickly” towards a nuclear weapon and could have one as early as In response , a U.

Honors Chemistry is designed for students who have demonstrated strong ability in previous science courses. In this fast-paced, demanding course, the main topics–which include atomic theory, nuclear chemistry, periodicity, chemical reactions, stoichiometry, gases, solutions, reaction kinetics, equilibrium, acid-base theory, oxidation-reduction, and organic chemistry–are studied at an.

Calculate the age of the calibration standards using the following information.

Explain if the instrument appears to be calibrated based on the data you obtained for the Low Calibration Standard. The scintillation instrument does appear to be calibrated because the sample was in low standard. Explain if the instrument appears to be calibrated based on the data you obtained for the High Calibration Standard. Explain which would be the best isotope from the Isotope Half-Life Chart to measure a 3 billion year old specimen.

Rubidium isotope would be the best isotope to use for that measurement because it contains the most years that would be needed to measure that span. Even with the help of this isotope the task would still be rather difficult to make precise. Activity 2 Place your data from Activity 1 in the appropriate boxes below.
