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.

  • Planck Units
  • Planck units are largely based upon three fundamental units, h, G, and c.
  • The gravitational constant is given the symbol "G". &nbsp; 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. &nbsp; 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. &nbsp; At various times, the laboratory equipment and methods were improved to arrive at more accurate values for G. &nbsp; 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. &nbsp; 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. &nbsp; Fundamental constants such as G often have two values according to the measuring system used. &nbsp; 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. &nbsp; Consequently, it is important to convert the various units of the fundamental constants used to the same system of units. &nbsp; 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. &nbsp; 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. &nbsp; For G, the following was discovered.

Squeezed light a small step forward toward detecting gravitational waves - 0 views

  • Gravitational waves are generated by accelerating masses. So, our planet, which is constantly accelerating towards the sun, is sending out a constant stream of gravitational waves. Just really small ones. Likewise, colliding neutron stars will emit a strong burst of gravitational waves. How strong? Well, if the stars were on the other side of our galaxy, a one meter bar on Earth would elongate by about 0.1am (attometer = 10-18m).&nbsp;

  • In a light field, the amplitude (a measure of the brightness of the light) and the phase (which controls how to combine light fields) can't both be measured with absolute accuracy—even if you had the perfect measuring device. You can picture the problem as bunches of photons popping into and out of existence, causing the phase and amplitude of the of the light to jitter around. This doesn't add or subtract energy, but it does continuously redistributes the energy along the light beam.

  • You might think that a photon here or there shouldn't make a difference, but the scaling isn't independent of the laser light entering the interferometer. If you have one photon, you will have a photon of noise. If you have four photons, you will have two photons of noise. The noise increases slower than the signal and the laser power is increased. So, the easiest way to improve the signal to noise ratio is to crank up the power.

Neural signature of mental time travel | ZME Science - 0 views

  • Neural signature of mental time travel
  • memory triggering
  • “By examining the patterns of brain activity recorded from the implanted electrodes,” Manning said, “we can measure when the brain’s activity is similar to a previously recorded pattern. When a patient recalls a word, their brain activity is similar to when they studied the same word. In addition, the patterns at recall contained traces of other words that were studied prior to the recalled word.” “What seems to be happening is that when patients recall a word, they bring back not only the thoughts associated with the word itself but also remnants of thoughts associated with other words they studied nearby in time,” he said.
