  • Planck Units
  • Planck units are largely based upon three fundamental units, h, G, and c.
  • The gravitational constant is given the symbol "G".   It is a measured value used in the force equation for gravity (see below). F = Gm1m2 / r2 The m units are masses of two bodies which are separated by a distance r.   By rearranging the equation, we have G (see below). G = Fr2 / m1m2 The gravitational force, F, was measured between two masses to arrive at G.   At various times, the laboratory equipment and methods were improved to arrive at more accurate values for G.   The physics texts were not usually updated for the new values because (1) the changes were not great enough to justify the added expense to the texts, and (2) the changes were happening frequently enough to make each text obsolete before it arrived in the hands of students.   Consequently, there are numerous variations of G to be found, but the differences between them are slight. There are many systems of weights and measures used in physics.   Fundamental constants such as G often have two values according to the measuring system used.   When two such units are mixed to arrive at subsidiary units such as the planck length, the result is a completely erroneous value along with units of measure which do not apply.   Consequently, it is important to convert the various units of the fundamental constants used to the same system of units.   In may instances of late, this has not been done. Finally, there is human error involved in copying from an old text to create a new next.   This means that it is wise to check various texts to see if they all agree (they usually don't), and decide what is correct and what is not correct.   For G, the following was discovered.

G = 6.6742x10-11 meter3/kilogram second2 From a science publication announcing an improved value based upon data from a recent experiment 1994.   Note that the the text mentioned below, probably written prior to 1994, did not include the change. G = 6.67259x10-11 newton meter2/kilogram2 From a textbook last copyrighted in 1997, Fundamentals of Physics Extended.  
  • 1 newton = 1 kilogram of force = 1 kilogram of mass x 1 meter/second2 = 100,000 dynes
  • For h, the following was discovered. h = 6.6252x10-34 joule second   or   4.134x10-15 electron volt second
  • 1 joule = 10,000,000 ergs = .737324 (one book gave .7376) foot pounds = 1 watt second = .1020 kilogram meter
  • The joule is defined as the unit of work or energy equivalent to work done or heat generated in one second by an electric current of one ampere against a resistance of one ohm - or raising the potential of a coulomb by one volt.
  • The erg is defined as the unit of work and of energy, being the work done in moving a body one centimeter against a force of one dyne. 1 erg = one centimeter dyne = 980.7 centimeter grams = 107 joules = 107 watt seconds The electron volt (sometimes called the equivalent volt) is defined as the unit of energy equal to that acquired by an electron passing through a potential of one volt.

FutureTechToday.com: Water-Revitalization Technology for Better Vitality - 0 views

  • Water is a polar molecule which means that one side of the molecule is more positively charged while the other side is more negatively charged. The result of this charge differential is an attraction between molecules making water a much more complex substance than mainstream science (Quantum Physics, etc.) has ever given it credit for! It is this attractive force between water molecules which causes water to form droplets rather than a molecular mist. These attractive forces also result in clusters of water molecules in nature which are very sensitive to environmental conditions. In nature, if we observe water closely we see (as it does flowing down a drain) it move in circular paths in order to maintain a high energy or frequency state. Molecular spin is an important factor when considering the polar attraction between water molecules; it makes common sense that faster molecular spin will decrease this molecular attraction and consistent or resonant molecular spin may have an ordering or structuring effect. Municipal water systems utilize straight pipes which carry water long distances under high pressures dampening the molecular spin of water causing much larger clusters of molecules locking up the hydration power of water! This can be measured as surface tension. Natural spring water is considered "living water" due to the high frequency molecular spin and the vibrancy of nature.

Quantum causal relations: A causes B causes A - 0 views

  • In everyday life and in classical physics, events are ordered in time: a cause can only influence an effect in its future not in its past. As a simple example, imagine a person, Alice, walking into a room and finding there a piece of paper. After reading what is written on the paper Alice erases the message and leaves her own message on the piece of paper. Another person, Bob, walks into the same room at some other time and does the same: he reads, erases and re-writes some message on the paper. If Bob enters the room after Alice, he will be able to read what she wrote; however Alice will not have a chance to know Bob's message. In this case, Alice's writing is the "cause" and what Bob reads the "effect". Each time the two repeat the procedure, only one will be able to read what the other wrote. Even if they don't have watches and don't know who enters the room first, they can deduce it by what they write and read on the paper. For example, Alice might write "Alice was here today", such that if Bob reads the message, he will know that he came to the room after her.

Magnetic pressure - Wikipedia, the free encyclopedia - 0 views

  • Magnetic pressure
  • Magnetic pressure is an energy density associated with the magnetic field.
  • Interplay between magnetic pressure and ordinary gas pressure is important to both the fields of magnetohydrodynamics and plasma physics. Any magnetic field has an associated pressure that is contained by the boundary conditions on the field, and a gradient in field strength causes a force due to the magnetic pressure gradient; this force is called the magnetic pressure force.

Scientists suggest spacetime has no time dimension - 0 views

  • Scientists propose that clocks measure the numerical order of material change in space, where space is a fundamental entity; time itself is not a fundamental physical entity.
  • They propose to replace these concepts of time with a view that corresponds more accurately to the physical world: time as a measure of the numerical order of change.
  • No time dimension

  • “Einstein said, ‘Time has no independent existence apart from the order of events by which we measure it,’”
  • “Newton theory on absolute time is not falsifiable, you cannot prove it or disprove it, you have to believe in it,” Sorli said. “The theory of time as the fourth dimension of space is falsifiable and in our last article we prove there are strong indications that it might be wrong. On the basis of experimental data, time is what we measure with clocks: with clocks we measure the numerical order of material change, i.e., motion in space.”
