A Hunk Of Planet Dissolves Before Our Eyes It begins with a growl. Then there's a crack — a slurpy, sucky, crunchy noise. A guy is on the phone, and his pal interrupts him and says, "It's starting, Adam, I think. Adam? Over 500 Social Change Documentaries on 1 Page Just imagine what could become possible if an entire city had seen just one of the documentaries above. Just imagine what would be possible if everyone in the country was aware of how unhealthy the mainstream media was for our future and started turning to independent sources in droves. Creating a better world really does start with an informed citizenry, and there's lots of subject matter to cover.
» Was That A UFO That Attacked A Taliban Camp In Afghanistan This incredible video shows the moment a UFO attacks and destroys a Taliban base in Afghanistan. The one minute 35 second clip, uploaded to YouTube, begins with footage of a large, grey triangular-shaped ‘craft’ hovering in the sky above the eastern city of Asadabad. As the crew of a Nato armoured vehicle watch on in the foreground, flashing lights suddenly flash spit forth from the underside of the mysterious object. It quickly becomes apparent that the craft has opened fire on something or someone, for barely a second later, explosions can be seen and heard and a huge plume of smoke mushrooms into the firmament.
Mega Geometry: January 2015 A Short Lesson in Music Theory Pythagoras was the first one credited with realizing that a string could be cut at certain ratios to produce harmonically pleasing sounds. This idea undoubtedly predates Pythagoras, as it is the basis for all musical theory, and he likely encountered it in Egypt or one of the many places he traveled in his youth. Pythagoras constructed his scale using only perfect fifths (3/2) and octaves (2/1). The Feynman Lectures on Physics Vol. II Ch. 10: Dielectrics 10–1The dielectric constant Here we begin to discuss another of the peculiar properties of matter under the influence of the electric field. In an earlier chapter we considered the behavior of conductors, in which the charges move freely in response to an electric field to such points that there is no field left inside a conductor. Now we will discuss insulators, materials which do not conduct electricity.
Archimedes' principle - Wikipedia Buoyancy principle in fluid dynamics Explanation A floating ship's weight Fp and its buoyancy Fa must be equal in size. In On Floating Bodies, Archimedes suggested that (c. 250 BC): Any object, wholly or partially immersed in a fluid, is buoyed up by a force equal to the weight of the fluid displaced by the object. Ancient Babylonian Use of the Pythagorean Theorem and Its Three Dimensions By Luis Teia, contributing writer for Ancient-Origins.net Very much like today, the Old Babylonians—20th to 16th centuries BC—had the need to understand and use what is now called the Pythagoras’ (or Pythagorean) theorem. They applied it in very practical problems such as to determine how the height of a cane leaning against a wall changes with its inclination. This sounds trivial, but it was one of the most important problems studied at the time. A remarkable Old Babylonian clay tablet, commonly referred to as Plimpton 322, was found to store combinations of three positive integers that satisfy Pythagoras’ theorem.
What Is The Significance Of The Number 9? by Luke Miller Truth Theory Is there a divine code embedded in our number system? Vortex based mathematics says yes! This eye opening video reveals why the number 9 is perhaps the most significant number there is. So what do you think? New Physics Formula Links Quantum Mechanics And Pure Math The notorious number Pi has succeeded in becoming even more prevalent in science. Researchers from the University of Rochester discovered that a formula which approximates the energy levels of a hydrogen atom is the same as the one developed 360 years ago by English mathematician John Wallis to find the value of Pi. The pair of physicists realized that when the variational method was employed to calculate the energy levels of the hydrogen atoms, the formula could be simplified into the Wallis Product, the one used for Pi. The variational method is used to approximate the lower energy states of atoms, when the electrons are close to the nucleus. It is not usually used on the hydrogen atom, as hydrogen is simple enough so scientists can compute the energy levels precisely. Energy levels give an indication of how tightly bound the electron is to an atom; the larger the energy level, the easier it is for the electron to break free.
Revolutionary theory of dark matter The universe abounds with dark matter. Nobody knows what it consists of. University of Oslo physicists have now launched a very hard mathematical explanation that could solve the mystery once and for all. Astrophysicists have known for the last 80 years that most of the universe consists of an unknown, dark matter. The solution to the mystery may now be just around the corner. "We are looking for a new member of our particle zoo in order to explain dark matter. Thermonuclear Fusion, Nuclear Reactions The smallest particle of matter which can be exist in nature is known as atom. Professor Henri Becquerel proved that each atom is un dividable particle. Each atom consist of three basic particles; electron, proton and neutron.
