  • 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.

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.

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). 
  • orbit of an electron around a hydrogen atom (about 0.05nm),
  • 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.

  • Regulatory Changes by the Federal Energy Regulatory Commission
  • FERC Orders 888 and 889
  • On April 24, 1996, FERC issued Orders 888 and 889, which encourage wholesale competition.  The primary objective of these orders is the elimination of monopoly power over the transmission of electricity.  To achieve this objective, FERC requires all public utilities that own, control, or operate facilities used for transmitting electric energy in interstate commerce to: file open access nondiscriminatory transmission tariffs containing minimum terms and conditions, take transmission service (including ancillary services) for their own new wholesale sales and purchases of electricity under open access tariffs, develop and maintain a same-time information system that will give existing and potential  users the same access to transmission information that the public utility enjoys, and separate the transmission from generating and marketing functions and communications.

  • Recovery of stranded costs is perhaps the most contentious issue confronting regulators in promoting competition.  Stranded costs (or assets) are costs that have been prudently incurred by utilities to serve their customers but cannot be recovered if the consumers choose other electricity suppliers. One study has estimated current stranded assets at $88 billion, and estimates of projected stranded costs range from $10 billion to $500 billion. In its Order 888, FERC reaffirmed "that the recovery of legitimate, prudent and verifiable stranded costs should be allowed." FERC's directive is grounded in the belief that the recovery of stranded costs "is critical to the successful transition of the electricity industry to a competitive, open-access environment." For this purpose, direct assignment of costs to departing customers was selected as the appropriate method for recovery of stranded costs.

Chaos - 0 views

  • In the framework of complex dynamical systems we can view the world at the beginning of this century as loosely connected with clusters of highly complex trouble spots and the number of people with a global perspective and fast connections was very small. Today we have multiple systems of global information exchange together with impressive data and information systems accessible for a rapidly growing number of people. We claim that the a global computer network will have a much more dramatic impact on global issues than other networks of global communication systems like television or telephone. In the first case we obtain many features that we can associate with the development of biological brains whereas in the two latter cases many essential features are missing. The most relevant one is the creation of the analog of cell assemblies.

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.”

Why is space three-dimensional? - 0 views

  •  
    (Phys.org)-The question of why space is three-dimensional (3D) and not some other number of dimensions has puzzled philosophers and scientists since ancient Greece. Space-time overall is four-dimensional, or (3 + 1)-dimensional, where time is the fourth dimension. It's well-known that the time dimension is related to the second law of thermodynamics: time has one direction (forward) because entropy (a measure of disorder) never decreases in a closed system such as the universe.

  • GE’s Brand New 100W Equivalent LED Bulb Illuminates the Future of Lighting May 7, 2012 Engineers at GE’s NELA Park in East Cleveland, Ohio, have spent a century building better light bulbs. When NELA opened in 1911, it became the world’s first industrial park, a distinction that earned it a place on the National Register of Historic Places. But now a new kind of history is taking place at NELA, the kind that will soon dispatch the incandescent light bulb down the same road traveled by the LP and the VCR. “This is an evolution,” says Glenn Kuenzler, a lighting engineer at NELA. He and his team of researchers are making sure that the GE bulb, whose legacy stretches back to Edison, is fit to survive.

Heliophysics nugget: Riding the plasma wave - 0 views

  • Throughout the universe more than 99 percent of matter looks nothing like what's on Earth.
  • This material that pervades the universe, making up the stars and our sun, and also – far less densely, of course – the vast interstellar spaces in between, is called plasma. Plasmas are similar to gases, and indeed are made of familiar stuff such as hydrogen, helium, and even heavier elements like iron, but each particle carries electrical charge and the particles tend to move together as they do in a fluid.
  • "Which particles are moving, what is the source of energy for the motion, how does a moving wave interact with the particles themselves, do the wave fields rotate to the right or to the left – all of these get classified," says Lynn Wilson who is a space plasma physicist at NASA's Goddard Space Flight Center in Greenbelt, Md.
