A physicist is a scientist who studies or practices physics. Physicists study a wide range of physical phenomena in many branches of physics spanning all length scales from sub-atomic particles of which all ordinary matter is made ( particle physics) to the behavior of the material Universe as a whole ( cosmology). The term "Physicist" was coined by the English philosopher, priest, and historian of science William Whewell in 1840, to denote a cultivator of physics.[1] Most material a student encounters in the undergraduate physics curriculum is based on discoveries and insights of a century or more in the past. Alhazen's intromission theory of light was formulated in the 11th century; Newton's laws of motion and Newton's law of universal gravitation were formulated in the 17th century; Maxwell's equations, 19th century; and quantum mechanics, early 20th century. The undergraduate physics curriculum generally includes the following range of courses chemistry, classical physics, astronomy, physics laboratory, electricity and magnetism, thermodynamics, optics, modern physics, quantum physics, nuclear physics, particle physics, and solid state physics. Undergraduate physics students must also take extensive mathematics courses (calculus, differential equations, advanced calculus), and computer science and programming. Undergraduate physics students often perform research with faculty members. Many positions, especially in research, require a doctoral degree. At the Master's level and higher, students tend to specialize in a particular field. Fields of specialisation include experimental and theoretical astrophysics, atomic physics, molecular physics, biophysics, chemical physics, condensed matter physics, cosmology, geophysics, material science, nuclear physics, optics, particle physics, and plasma physics. Post-doctoral experience may be required for certain positions.

1. Did You Know You Should Apply Newton?s Number One Success Secret In Your Internet Business?
November 01, 2009
Can you recall all Isaac Newton's accomplishments?
Let me refresh you a bit: Sir. Isaac Newton was a physicist, mathematician, astronomer, natural philosopher, alchemist, and theologian; in conclusion one of the most influential men in human history.
When close to the end of his days, someone asked him what he thought was the best advice he could give to others, who wanted to be successful in life. What was the secret?
His plain and smart answer was: "Stand on the shoulders of a giant to see further than the giant."
I give several interpretations to this phrase: "The sm... (read more)

2. Integrating Your 4 Freedoms (Part 2 of 9) - String Theory
October 29, 2009
String Theory
The theory of strings, sometimes referred to as the theory of everything,i is considered by many physicists to be the most promising explanation to date for the nature of ultimate reality. It suggests the possibility that there is a connection, as well as a separation, between the realms of the material and consciousness. Both conditions can exist at the same time.
According to physicist David Gross:
There is about as complete unification as one could desire. Within this theory one is not saying that there are a few kinds of objects, and that everything else is bui... (read more)

3. The Discovery, Creation and Uses of Electromagnets
October 07, 2009
Most people are not aware of the many applications electromagnets have in our modern day life. Though we may be awed to see a car being lifted, we may not realize there are much smaller applications that make our life easier and more productive, all thanks to a few ingenious engineers and scientist who made this great discovery just over two centuries ago.
How the Electro Magnet was invented
In 1820 a Danish physicist named Hans Christian Oerstead discovered there was a relationship between magnetism and electricity, concluding that electricity had the ability to create a magne... (read more)

Radiology / X-Ray – a fascinating world of medicine and technology!
Did you know that x-rays were invented by accident?
In 1895, a German physicist named Wilhelm Conrad Roentgen made a discovery, which he later termed “x-rays,” while experimenting with an electron beam in a gas discharge tube. Roentgen noticed that a fluorescent screen in his lab started to glow when the electron beam was turned on. Roentgen's tube was surrounded by heavy black cardboard, so he continued to investigate what mysterious entity might be traveling right through matter. This discovery laid the foundatio...

10. Bifocal Glass History
June 22, 2009
Glass lenses, for use as magnifiers or for starting fires, date to about 300 BC, but the first eyeglasses to aid or correct vision were almost certainly invented in 1280 in Florence, Italy by the Dominican friar Alessandro della Spina and his friend, the physicist Salvino degli Armati. Prescribed for far-sightedness, the glasses had convex lenses and were worn by Armati, who had injured his eyes while performing light refraction experiments and discovered that it was possible to enlarge the appearance of objects by looking through two pieces of convex glass. It was in the early fourteenth... (read more)

11. KNOW-HOW'S OF THE 12-VOLT BATTERY
May 19, 2009
Before we launch into details of the 12-volt battery, let’s briefly understand how a standard battery works?
A battery, defined by the dictionary, is a device that converts chemical energy directly to electrical energy. Possibly the first ever chemical battery – voltaic pile – was developed by Italian physicist, Alessandro Volta (1745–1827). The unit of measurement of the battery is Voltage (measured in Volts). Batteries can be divided into two categories: Primary or non-rechargeable batteries and Secondary or rechargeable batteries. Example of Primary batteries – Alkaline, Lithium and S... (read more)

14. Laser "Light Bullets" Made to Curve
April 14, 2009
Laser "light bullets" that can curve through the air might someday help scientists monitor air pollution, a new study says.
The bullets are created by extremely short-duration, high-intensity laser pulses, said lead study author Pavel Polynkin, a physicist at the University of Arizona.
The pulses are so rapid that the beam is broader than it is wide—creating what Polynkin calls "pancakes" of light.
But the use of complex lasers that produce wave patterns called Airy beams causes the brightest part of the beam to bend as the pancake of light speeds away.
The super-brightness... (read more)

22. Making what you want a certainty
March 09, 2009
Richard Feynman, the great quantum physicist and educator said in one of his lectures that just because something is possible does not mean it is probable. So often we claim something is true because it is possible, and that something is untrue because improbable. The truth is if something is true it is true no-matter improbable it is. And, in reverse untrue is untrue no-matter how probable it seems. If there is no proof either way it remains a probability. We spend our lives looking for certainty and yet all we have all we have is varying degrees of probability because virtually not... (read more)
