Therefore, it can cool its surrounding region. Thus, it can be used in a refrigerator. There is no noise as no motors are run.
<br><br>
It is also safer as the regular refrigerators cause damage to the ozone layer by releasing harmful gases.
<br><br>
However, one limitation is that with the current technology, the efficiency of such refrigerators is rather low.

What I am going to tell you about is what we teach our physics students in the third or fourth year of graduate school... It is my task to convince you not to turn away because you don't understand it. You see my physics students don't understand it... That is because I don't understand it. Nobody does.

<br>
Even if there is only one possible unified theory, it is just a set of rules and equations. What is it that breathes fire into the equations and makes a universe for them to describe? The usual approach of science of constructing a mathematical model cannot answer the questions of why there should be a universe for the model to describe. Why does the universe go to all the bother of existing?

The Scanning Tunneling Microscope works on the principle of tunneling, i.e. the <a href="introduction-to-quantum-physics.html" class="center">quantum physical</a> phenomenon which makes electrons go through regions where they are not allowed to go classically.
<h3>WORKING:</h3>
The Scanning Tunneling Microscope consists of a platinum-rhodium or tungsten needle. This is the probe. This needle type stylus (or the probe) is scanned through the surface to be observed. The surface should be conducting. When the probe is brought close to the surface, electrons can tunnel through the gap. This is observed as a current.
<br><br>
There are two modes of working of the Scanning Tunneling Microscope - the constant current mode and the constant-z mode.
<br><br>
In the <b>constant current mode</b> of working of the scanning tunneling microscope, a needle (stylus or the probe) moves through the surface of the sample to be scanned, and moves up and down according to the structure of the surface. For example, at places where there is a rise at the surface, the scanning stylus moves up and at depressions, moves down.
<br><br>
This moving up and down of the probe is achieved by fixing it to a piezoelectric cylinder, which expands or contracts according to the <a href="electric-potential.html" class="center">potential</a> difference applied to it. In this way, the surface of the given sample can be observed. The tip of the probe can be made as sharp as just one atom thick. So, the surface can be observed very precisely, down to the <a href="introduction-to-atomic-physics_05.html" class="center">atomic</a> scale.
<br><br>
Moving the probe up and down according to the rises and falls of the sample surface keeps the distance between the stylus and the surface constant. This in turn keeps the tunneling current constant as tunneling current depends on the distance between the stylus and the surface.
<br><br>
In the <b>constant-z mode</b> of operation, the vertical tip of the probe is held constant, and the current through it is monitored. The tunneling probability is very sensitive to the size of the gap. So, atomic-scale variations in height of the surface can be observed.

Time travel, or the ability to travel backwards or forwards in time at will, has fascinated everyone from researchers and students to fiction authors and anyone at all who has ever thought over such a possibility.
<br><br>
The theory of physics that comes the closest to saying anything about time travel is the theory of relativity. The theory of relativity was given by Albert Einstein and describes some extraordinary effects that become noticeable as a particle approaches the speed of light. The relativistic effect of time dilation, which describes a condition in which time appears to be moving at different rates for two observers in different reference frames, in one such counter-intuitive effect that comes close to time travel.
<br><br>
While there are many theories that support, or at least provide an argument, on how time travel might be possible, there are other counter-arguments that describe the paradoxes that the concept of time travel leads to. Some scientists use the concepts like wormholes, parallel universes and quantum entanglement to propose time travel mechanisms. However, another kind of arguments refutes the possibility of time travel by giving examples of paradoxes such as the grandfather paradox.
<br><br>
More to come...

<br><br>
The basic difference between photography and holography is that while in a photograph, only the information about the intensity distribution of light at different points in the area being photographed is recorded, in holography, the information about the phase of light is also recorded. This gives a three-dimensional image which resembles the object.vibhavhttp://www.blogger.com/profile/10971697850846357769noreply@blogger.com0tag:blogger.com,1999:blog-20438925.post-1137348265028590072006-01-05T23:16:00.007+05:302006-10-14T17:57:49.315+05:30BoseSatyendra Nath Bose was born on January 1, 1894 in Calcutta (now Kolkata), India.

He was born in Ulm, Germany on March 14,1879. He spent his childhood in Munich and moved to Switzerland when he was 15.
<br><br>
In the year 1905, Einstein published three significant papers. In the paper titled "On the Theory of Brownian Motion", he published a proof of the <a href="http://physics-help.blogspot.com/2006/01/history-of-atomic-physics.html" title="History of Atomic Physics" class="center">atomistic</a> nature of matter. This theory of Brownian motion was confirmed experimentally a few years later.
<br><br>
In his second paper titled "On the Electrodynamics of Moving Bodies", Einstein gave the <a title="Principles of Relativity" href="principles-of-relativity.html" class="center">special theory of relativity</a>. This theory included a new look at the conventional ideas of space and time, and the famous mass energy equivalence principle.
<br><br>
In the third paper titled "On a Heuristic Viewpoint Concerning the Production and Transformation of Light", Einstein explained the <a href="photoelectric-effect.html" title ="Photoelectric Effect" class="center">photoelectric effect</a> using <a href="planck.html" title ="Max Planck" class="center">Planck's</a> idea of quantization of energy in radiation. The classical theory of radiation was unable to explain this effect.
<br><br>
Einstein recieved the <a href="http://nobelprize.org/physics/laureates/1921/index.html" title="1921 Nobel Prize - Physics" class="center">Nobel Prize in 1921</a> for the explanation of the photoelectric effect and for his services to theoretical physics.
<br><br>
Einstein also created the General Theory of Relativity - the modern theory of gravitation. He introduced the idea of stimulated emission which is crucial for the working of the <a href="http://physics-help.blogspot.com/2006/01/laser.html" title="Laser" class="center">laser</a>. Later in his life, Einstein also worked on Cosmology.<br><br>

<br><br>
He became a professor at Washington university in 1920 and at the University of Chicago in 1923.
<br><br>
Compton discovered the effect known after him as the <a class="center" href="compton-effect.html">Compton effect</a> in 1922 while investigating X-rays. ("The spectrum of Scattered X-rays", Physical Review, 1923). He also gave the theoretical explanation for this effect. ("A Quantum Theory of the Scattering of X-rays by Light Elements", Physical Review, 1923)
<br><br>
He was awarded the Nobel Prize in physics in 1927 together with C.T.R. Wilson.

<br><br>
In 1920, Bohr became the director of the Insitute of Theoretical physics at the University of Copenhagen.
<br><br>
Bohr applied Planck's hypothesis of energy quantization to atoms and explained the spectral lines with his model of the atom. He gave a relation between <a href="introduction-to-classical-mechanics.html" class="center">classical physics</a> and <a href="introduction-to-quantum-physics.html" class="center">quantum mechanics</a> by his Correspondence Principle. He developed the Copenhagen Interpretation of quantum mechanics together with <a href="heisenberg.html" class="center">Heisenberg</a>. He also worked on <a href="introduction-to-nuclear-physics.html" class="center">nuclear physics</a>.vibhavhttp://www.blogger.com/profile/10971697850846357769noreply@blogger.com0tag:blogger.com,1999:blog-20438925.post-1137347183976742062006-01-05T23:15:00.000+05:302006-10-14T17:57:48.649+05:30Famous PhysicistsRead about the lives and careers of some famous physicists who have had a profound effect on the development of physics.

There are many other applications of optics using lens systems, mirrors, lasers and diffraction gratings etc. Many beautiful experiments can be designed in Optics and put to various uses.
<br><br>
The field of ray optics is used to design and use the Microscope, the Telescope and cameras. There are various designs of the microscope which give different levels of magnification and resolution. The telescope, similary has different types of designs.
Optics is also used in the design of precision components and systems. Precise instruments are important in machine design and testing.
<br><br>
Other applications include using spectrometers to analyze the spectrum of a source, and hence to deduce its characteristics. This method is called spectroscopy. Spectroscopy can be used to analyze the atomic structure of atoms, or the composition if a source.
<br><br>
The field of fiber optics is advanced and still a large amount of research is going on in fiber optics. This field is useful in communication systems. Fibers form the backbone of many communication systems.
<br><br>
<a href="holography.html" class="center">Hologrpahy</a> is yet another field of optics which holds promises in data storage.
