Will Your Computer Make You Go Blind?
Strain on the eye from computer use comes from a several sources. The first is a constant working distance typical of computer users. Two sets of muscles work in tandem to see your screen clearly. One set converges the eyes onto the same point. The other set actually flexes and fattens up the crystalline lens in each eye to properly focus light rays from the computer onto the retina.
As with any muscle in the body, continuous flexing can create repetitive stress problems. Ever have blurred vision when looking away from the screen? This may be a spasm of the ciliary muscles causing focus to "lock," thereby creating a temporary loss of distance vision. Other symptoms may include blurred vision, the inability to properly focus on the screen, or even a good old-fashioned headache.
Ever find that your eyes have an irritated "scratchy" feeling after a long session using the computer? A relatively normal blink rate is 12-15 blinks per minute, but computer users tend to blink much less frequently, more typically around 4-5 blinks per minute.
Why? The eyes normally jump around the screen in pattern called a "saccade." Blinking disrupts this pattern and lowers productivity for someone concentrating on an intense visual task, especially when under deadline to get a big project done. Blink less and you get more done... but it can take a toll on your eyes.
A dry, scratchy sensation is a common symptom of dry eyes. Interestingly, in some cases, computer users actually suffer watery eye symptoms due to the fact that the eyes are irritated but the reduced blink rate doesn't spread the tears effectively.
Another reason your eyes strain when using the computer relates to the quality of light emitted from the screen. "In simplest terms, it's like you're looking at a lightbulb for hours on end," says Anshel. "Not to mention the fact that today's LCD screens are almost all backlit with fluorescent light, which is harsh on your eyes to begin with."
In an effort to reduce the amount of energy consumed, screen manufacturers use very narrow bands of the visual spectrum to light the screen. Combined with overhead fluorescent office light, the harsh artificial light is far from full spectrum daylight that the eye likes to see.
In an effort to improve the quality of light, often computer users will put the computer close to windows or other more natural light sources. However, improperly-placed lighting can actually cause problems due to screen glare or over-illumination of the eye, which causes the pupil to constrict and makes the screen harder to see.
As eyestrain affects normal vision, secondary problems may occur as well. "Walk around the office and notice how many people are hunched in toward the computer to see the screen better," prompts Anshel. "With poor ergonomic posture, it's easy to see how computer vision problems can create head, neck, and back pain."
The good news is that there are a number of ways to prevent or lessen the strain felt while viewing a computer. Many are quick or inexpensive solutions to address certain parts or the problem. For example, rearranging the workplace for proper posture, viewing angle, and lighting can help out.
Dr. Anshel suggests, "Make sure you have your computer far enough away to comfortably see it. Ideally, the center of the screen is 7-10 inches below your horizontal line of sight. Move your lights to where they don't cause any glare and to where you don't have any bright objects, like a window, in your field of view when viewing the screen." He also suggests a series of breaks during the workday.
The smallest should occur every 10 minutes and can be as short as 10 or 20 seconds. To properly relax the eye muscles, you must look at least 20 feet away. At least once each hour, take a bigger break that includes standing and stretching. An eye doctor can recommend specific eye exercises during these bigger breaks to help further relax eye muscles.
Several commercial solutions are available for sale to help alleviate Computer Vision Syndrome. Glare protectors are an easy fix for both older CRT monitors and some newer screens that have a glossy surface. Reflections may create awkward posture if the glare prevents you from seeing the screen from a straight-on view.
Certain software is also available to help users remember to take breaks, blink more often, or even change the color of the screen to adapt to different times of the day in an effort to limit blue light, which may affect sleep patterns.

'The Evolution of Matter' and 'The Evolution of Forces' on CD
Years ago, I had been told by several people, that the US government frequently removes books they deem dangerous or 'sensitive' from libraries. Some are replaced with sections removed or rewritten so as to 'contain' information that should not be available to the public despite the authors intent. A key example was during the Manhattan Project when the US was trying to finalize research into atomic bombs. They removed any books that dealt with the subject and two of them were by Dr. Gustave Le Bon since they dealt with both energy and matter including radioactivity. I had been looking for these two books for many years and fortunately stumbled across two copies for which I paid about $40.00 each. I couldn't put down the books once I started reading them. Such a wealth of original discoveries, many not known or remembered today. / Page 88 - Without the ether there could be neither gravity, nor light, nor electricity, nor heat, nor anything, in a word, of which we have knowledge. The universe would be silent and dead, or would reveal itself in a form which we cannot even foresee. If one could construct a glass chamber from which the ether were to be entirely eliminated, heat and light could not pass through it. It would be absolutely dark, and probably gravitation would no longer act on the bodies within it. They would then have lost their weight. / Page 96-97 - A material vortex may be formed by any fluid, liquid or gaseous, turning round an axis, and by the fact of its rotation it describes spirals. The study of these vortices has been the object of important researches by different scholars, notably by Bjerkness and Weyher. They have shown that by them can be produced all the attractions and repulsions recognized in electricity, the deviations of the magnetic needle by currents, etc. These vortices are produced by the rapid rotation of a central rod furnished with pallets, or, more simply, of a sphere. Round this sphere gaseous currents are established, dissymetrical with regard to its equatorial plane, and the result is the attraction or repulsion of bodies brought near to it, according to the position given to them. It is even possible, as Weyher has proved, to compel these bodies to turn round the sphere as do the satellites of a planet without touching it. / Page 149 - "The problem of sending a pencil of parallel Hertzian waves to a distance possesses more than a theoretical interest. It is allowable to say that its solution would change the course of our civilization by rendering war impossible. The first physicist who realizes this discovery will be able to avail himself of the presence of an enemy's ironclads gathered together in a harbour to blow them up in a few minutes, from a distance of several kilometres, simply by directing on them a sheaf of electric radiations. On reaching the metal wires with which these vessels are nowadays honeycombed, this will excite an atmosphere of sparks which will at once explode the shells and torpedoes stored in their holds. With the same reflector, giving a pencil of parallel radiations, it would not be much more difficult to cause the explosion of the stores of powder and shells contained in a fortress, or in the artillery sparks of an army corps, and finally the metal cartridges of the soldiers. Science, which at first rendered wars so deadly, would then at length have rendered them impossible, and the relations between nations would have to be established on new bases."

The Physics of the Primary State of Matter
The Physics of the Primary State of Matter - published in the 1930s, Karl Schappeller described his Prime Mover, a 10-inch steel sphere with quarter-inch copper tubing coils. These were filled with a material not named specifically, but which is said to have hardened under the influence of direct current and a magnetic field [electro-rheological fluid]. With such polarization, it might be guessed to act like a dielectric capacitor and as a diode...
