Sense bei eLexi - das Onlinelexikon(Site not responding. Last check: 2007-10-12)
Although schoolchildren are still routinely taught that there are five senses (sight, hearing, touch, smell, taste; a classification first devised by Aristotle), it is generally agreed that there are at least nine different senses in humans, and a minimum of two more observed in other organisms.
A broadly acceptable definition of a sense would be "a system that consists of a sensory cell type (or group of cell types) that respond to a specific kind of physical energy, and that correspond to a defined region (or group of regions) within the brain where the signals are received and interpreted".
Neuroanatomists generally regard it as two senses, given that different receptors are responsible for the perception of colour (the frequency of light) and brightness (the energy of light).
Energy will be much cheaper in the future when solar power collectors can be manufactured much cheaper and better than now.
Also the energy cost for transportation of molecules, inefficiencies, computation and entropy reduction together are almost ten times less than the chemical energy." (Although I made a mistake here, entropy reduction is not an energy cost...) >You discuss diamonds as materials for nanotech devices.
The total energy required for all other operational steps is about a factor 10 less (and this could probably be improved, for example by slowing down the process).

The free energy of a reaction is related to the equilibrium constant of the reaction.
Because of the supramolecular arrangement of the machinery in the membrane, the free energy is transduced to a proton gradient.
Because creatine phosphate has a greater standard energy of hydrolysis than ATP, it is able to act as a reserve and phosphorylate ADP to ATP [local] by a substrate-level phosphorylation until the cell's supply of creatine phosphate is exhausted.
Physics - free-definition(Site not responding. Last check: 2007-10-12)
Physics (from Greek from φυσικός (physikos): natural, from φύσις (physis): Nature) is the study of energy and its interaction with matter (see chemistry, biology).
Because of the primacy of energy in terms of the history of the universe, because all matter must interact with energy to express its properties and engage in transformations, and because energy is the key player when matter is decomposed into its most basic parts, physics is often considered to be the fundamental science.
Configuration of High Polymers(Site not responding. Last check: 2007-10-12)
In these cases the energy of the barriers of rotation along the C-C bond should be exaggerated due to the larger size of the fluorine and bromine atoms in the chain.
The energy of the internal rotation in the monomer unit of Lexan, a uniquely rigid material composed of polycarbonate linear polymer featuring the compound bisphenol-A as part of the repeat unit, will also be examined.
This illustrates the interactions of the adjacent methyl hydrogens during the rotation as the hydrogens are in the eclipsed and staggered conformations.
Absorption spectrum -- Facts, Info, and Encyclopedia article(Site not responding. Last check: 2007-10-12)
An electron can jump to a higher orbit if it is given the exact amount of energy by one single photon, which is a ((physics) the smallest discrete quantity of some physical property that a system can possess (according to quantum theory)) quantum of energy.
Using E = hf, a photon'senergy is directly related to its frequency (and hence its wavelength).
Only those wavelengths that correspond to a jump of an electron to a higher orbit are absorbed by the gas.
Comparison of Relative Energies and Powers(Site not responding. Last check: 2007-10-12)
The energy is given in the standard SI unit of Joules.
After all, the energy in that cup of gas (around 8MJ) is the same as the energy in about a pound and a quarter of wood, which clearly isn't really comparable.
Anyway, on an energy basis, the cup is more like 4 pounds worth of high explosive(8 MJ for the cup of gas, 2 MJ for the pound of HE).
This file is an attempt to provide a comprehensive and detailed listing and explanation of terms frequently used, so that those new to the group/field will be able to understand what is being said, and to contribute with a minimum of confusion and frustration.
Ideally one would be able to extract the ash ions after diverting an appropriate fraction of their energy to heating the fuel ions, and then convert the remaining ash energy to electricity.
It takes far less energy to break apart a stable molecule into its constituent atoms than to divide a stable atom into two smaller atoms.) Note that in solids, atoms are typically two angstroms (2 x 10^-10 meters) apart; in air the gas molecules are about 30 angstroms apart.
Before 1945, the amount of energy humans could release from a chunk of mattersuch as an explosivewas limited to chemical energies, thousands of joules per gram.
In 1945, that energy jumped over a million-fold to nuclear levels, billions of joules per gram.
The worlds of economics, politics, and daily life were not transformed abruptly, just because achievable speeds and energies were.
