Physics

Crocodile Physics is like a well-stocked physics lab where you can experiment to your hearts content. Covering many syllabus topics, here is the hardware flattened for the small screen. There are masses, trolleys, lenses and electronic components to assemble, experiment and take measurements with. You can swing pendulums, change gravity, change angle of ramps to … Read more

In order to attempt to trace the origins of the modern science that we now refer to as physics, we must begin with the origin of the term itself. Taken from the Greek word physika meaning growth or nature, physics most obviously began as the intelligent study of the human environment (Webster 393). From superstition … Read more

Physics began when man first started to study his surroundings. Early applications of physics include the invention of the wheel and of primitive weapons. The people who built Stone Henge had knowledge of physical mechanics in order to move the rocks and place them on top of each other. It was not until during the … Read more

Since their discovery, the nature of quasars has been one of the most intriguing and baffling problems as evidenced by the following quotations: the problem of understanding quasi-stellar objects is one of the most important and fascinating tasks in all physics – G. Burbidge and Hoyle. The quasar continues to rank both as one of … Read more

Electromagnetic radiation is defined as the emission and transmission of energy in the form of electromagnetic waves (Chang, pp. 246). An electromagnetic wave consists of two waves at perpendicular planes, on representing the electrical field while the other represents the magnetic field. This spectrum is split up into about 81 octaves, much like the octaves … Read more

For a fusion reaction to take place, the nuclei, which are positively charged, must have enough kinetic energy to overcome their electrostatic force of repulsion. This can occur either when one nucleus is accelerated to high energies by an accelerating device, or when the energies of both nuclei are raised by the application of very … Read more

ADHD was first described by Dr. Heinrich Hoffman in 1845. A physician who wrote books on medicine and psychiatry, Dr. Hoffman was also a poet who became interested in writing for children when he couldn’t find suitable materials to read to His 3-year-old son. The result was a book of poems, complete with illustrations, about … Read more

The efficient way for teachers to teach students is to present information, skills, or concept of Direct Instruction. Direct Instruction refers to a rigorously developed, highly scripted method for teaching that is fast-paced and provides constant interaction between students and the teacher. (Effective Teaching Methods) Direct Instruction is a research basic module used to help … Read more

The Big Bang Theory It is always a mystery about how the universe began, whether if and when it will end. Astronomers construct hypotheses called cosmological models that try to find the answer. There are two types of models: Big Bang and Steady State. However, through many observational evidences, the Big Bang theory can best … Read more

Diamagnetics was discovered by Michael Faraday in 1846, but no one at the time thought that it could lead to any appreciable effects. William Thomson (Lord Kelvin), referring to levitation as the problem of “Mohamet’s coffin,” had this to say: “It will obably be impossible ever to observe this phenomenon, on account of the difficulty … Read more

John Dalton developed the first useful atomic theory of matter around 1803. In the course of his studies on meteorology, Dalton concluded that evaporated water exists in air as an independent gas. Solid bodies can’t occupy the same space at the same time, but water and air could. If the water and air were made … Read more

Before we can learn about the laser we need to know a little bit about light (since that is what a laser is made of). Light from our sun, or from an electric bulb, is called white light. It is really a mixture of all the different colours of light. The colours range from violet, … Read more

Thomas Alva Edison is the most famous inventor in American History. Edison designed, built, and delivered the electrical age. He started a revolution that would refocus technology, change life patterns, and create millions of jobs. He became famous for his scientific inventions, even though he was not a scientist. His real talent was his ability … Read more

The most difficult thing for a regime to achieve is that of acquiring the best ruler, with the consent of the ruled. Aristotle acknowledges this in his works The Politics, and Caius Marcius Coriolanus faces this difficult task in the Shakespeare play The Tragedy of Coriolanus. We even see this same difficult task arise in … Read more

The central part of Berkeley’s metaphysics seems paradoxical or even absurd. Its claim is that what we call solid, and indeed everything else that we find laid out in the three-dimensional physical word that is apparently around us, is only fictional. It appears to be there, but it does not really have an independent existence. … Read more

The electromagnetic spectrum is made up of six different types of waves. Radio waves, Microwaves, Infrared waves, Visible light, Ultraviolet light, X-rays and Gamma rays. The radio waves are used to transmit radio and television signals. The infrared waves are used to tell temperature of areas. Visible light is all the colors that we can … Read more
