Milestones in Physics: Circa 2 Billion BC - Prehistoric Nuclear ReactorMilestones in Physics: Circa 2 Billion BC - Prehistoric Nuclear Reactor - The world was stunned in 1972 when French physicist Francis Perrin discovered that nature had created the world's first nuclear reactor two billion years before humankind, beneath Oklo in Gabon, Africa. This natural reactor formed when a uranium-rich mineral deposit came in contact with groundwater, which slowed the neutrons ejected from the uranium so that they could interact with and split other atoms. Heat was produced, turning the water to steam, thus temporarily slowing the chain reaction. The environment cooled, water returned, and the process was repeated. Scientists estimate that this prehistoric reactor ran for hundreds of thousands of years, producing the various isotopes expected from such reactions that scientists detected at Oklo.

Massive laser at National Ignition Facility takes baby step toward fusion
Smarter America / Published August 27, 2013 FoxNews.com

It’s one small step for energy -- and one giant blast for lasers.
Lawrence Livermore’s National Ignition Facility announced Tuesday a successful test of its ultrapowerful laser system, which melds 192 laser beams into a single incredible burst of energy. On Aug. 13, the facility was activated for 14 billionths of a second and aimed at a tiny capsule of fuel. The result: approximately 350 trillion watts of power -- hundreds of times more than the entire United States consumes at any given instant.
“We’re working in a place where no human has ever gone before,” Ed Moses, principle associate director for NIF and Photon Science, told FoxNews.com. “We’re working on the bleeding edge of fusion physics.”
Fusion is similar to fission, where atoms are split releasing massive amounts of energy. But instead of being torn apart, atoms are welded together in fusion. It’s the same ongoing energy process in the sun and other stars, a "perfect power" because more energy is released than used. Fusion could solve the world’s energy problems -- if it's possible at all.
In the NIF, beams of light converge on pellets of hydrogen isotopes to create a controlled micro-explosion. As the beams move through a series of amplifiers, their energy increases. From beginning to end, the total energy grows from one-billionth of a joule to a potential high of 4 million joules, NIF says -- a factor of more than a quadrillion. The current test reached 1.7 million joules (or megajoules), though a test last year hit a record high of 1.85.
“Our goal is to get fusion burn -- more energy out than we put in.”

Milestones In Physics: 2,500 B.C. - Truss |
"Trusses are structures usually composed of several triangular units that are made from straight pieces of metal or wood connected by joints, or nodes. If all members of the truss lie in a plane, the truss is called a planar truss. For centuries, truss structures allowed builders to construct sturdy structures in an economical way, in terms of cost and use of materials. The rigid framework of a truss allows it to span great distances . . . Wooden trusses were used in ancient lake dwellings during the Early Bronze Age, circa 2500 B.C."

How much physics would we have to re-think if we ever discover negative mass? |
"In general relativity, gravity is described as a distortion of space time. Most vulgarized books use the simplified image of a 2D plane being bent downwards by a mass, so that any matter traveling in the area would have to follow the bending of the plane, which would then explain why things are attracted to one another.
"Keeping the same simplified metaphor, could we imagine something that would bend the plane upwards, thus causing objects to be repelled? Would such a thing be considered to have negative mass? Is the concept theoretically possible?" Asked By: Thomas G. from Belgium Ask a Physicist Answers: http://physicscentral.com/experiment/askaphysicist/physics-answer.cfm?uid=20140818013234 |

Milestones in Physics: 250 B.C. - Siphon
"A siphon is a tube that allows liquid to drain from a reservoir to another location. An intermediate location in the tube may actually be higher than the reservoir, yet the siphon still operates. No pump is required to maintain the flow of liquid since the flow is driven by differential hydrostatic pressures. The discovery of the siphon principle is often attributed to the Greek inventor and mathematician Ctesibius . . . [One] application is the fanciful Tantalus Cup. In one form, the statue of a little man sits in the cup. A siphon is hidden in the statue with the crest near the level of the man's chin. As the liquid is poured into the cup, it rises to the chin, and then the cup promptly continues to drain most of the cup's contents through the siphon's end that is hidden at the bottom! Tantalus is, therefore, thirsty forever." (The Physics Book, by Clifford A. Pickover, Barnes & Noble, NY, 2013)

Infrared Nanoparticles Track Cancer Therapy
Tumor metastasis is associated with a physiological change in the tumor cells that gives them much greater mobility. A bone protein called BMP-7 is an important regulator of this physiological change. Researchers are studying the ability of BMP-7 to reverse the mobility of metastatic cells. In this image, researchers image the uptake of fluorescent nanoparticles (red) into kidney cell, whose nuclei are stained blue.

Milestones in Physics: 230 B.C. – Pulley“A
pulley is a mechanism that usually consists of a wheel on an axle. A rope runs over the wheel so that the pulley
can change the direction of an applied force, for example, when helping a human
or a machine lift or pull heavy loads. . . . The pulley probably had its birth
in prehistoric times when someone tossed a rope over a horizontal tree branch
and used it to lift a heavy object.
Author Kendall Haven writes, ‘By 3000 B.C., such pulleys with grooved
wheels (so that the rope wouldn’t slip off) existed in Egypt and Syria. The Greek mathematician and inventor
Archimedes gets credit for inventing the compound pulley in about 230
B.C. . . . in which a number of wheels and ropes combine to lift a single
object . . . to multiply the lifting power of a person. Modern block-and-tackle systems are examples
of compound pulleys.’ ” (The Physics

Milestones in Physics: 50 A.D. – Gears
“Rotating gears with their intermeshed teeth, have played a crucial role in the history of technology. Not only are gear mechanisms important for increasing the applied twisting force, or torque, but gears are also useful for changing the speed and direction of force. . . . Built around 125 B.C., the Antikythera Mechanism employed toothed gears for calculating astronomical positions. One of the earliest written references to toothed gears was made by Hero of Alexandria, circa A.D. 50. . . . When two gears are intermeshed, the rotational speed ratio s1/s2 is simply the reciprocal ratio of the number n of teeth on the two gears: s1/s2 = n2/n1 . Thus a small gear turns faster than its larger partner. The torque ratio has an opposite relationship. The larger gear experiences greater torque, and the higher torque implies lower velocity.” (The Physics Book, by Clifford A. Pickover, Barnes & Noble, NY, 2013)

Milestones in Physics: 78 A.D. -- St. Elmo's Fire
“Often described as a ghostly blue-white dancing flame, this is actually an electrical weather phenomenon in which a glowing plasma, or ionized gas, emits light. The plasma is created by atmospheric electricity, and the eerie glow often appears at the tips of pointed objects such as church towers or the masts of ships during stormy weather. St. Elmo was the patron saint of Mediterranean sailors, who regarded St. Elmo's fire as a good omen because the glow was often brightest near the end of a storm. Sharp pointed objects encourage the formation of the "fire" because electric fields are more concentrated in areas of high curvature. Pointed surfaces discharge at a lower voltage level than surfaces without points. The color of the fire arises from the nitrogen and oxygen composition of the air and their associated fluorescence. . . . 'On dark stormy nights,' writes scientist Philip Callahan, 'St. Elmo's fire is probably responsible for more ghost stories and tales of apparitions than any other natural phenomenon.' ” (The Physics Book, by Clifford A. Pickover, Barnes & Noble, NY, 2013)

Milestones in Physics: 1304 – Explaining the Rainbow
“Today we know that the attractive colors of the rainbow are a result of sunlight that is first refracted (experiences a change in direction) as it enters the surface of the raindrop, and then is reflected off the back of the drop toward the observer, and refracted a second time as it leaves the drop. The separation of white light into various colors occurs because different wavelengths – which correspond to various colors – refract at different angles. The first correct explanations of rainbows, which involved two refractions and a reflection, were independently provided at about the same time by Kamal al-Din al-Farisi and Theodoric of Freiberg. Al-Farisi was a Persian Muslim scientist born in Iran who conducted experiments using a transparent sphere filled with water. Theodoric of Freiberg, a German theologian and physicist, used a similar experimental setup. It is fascinating the degree to which simultaneous discoveries appear in great works of science and mathematics.” (The Physics Book, by Clifford A. Pickover, Barnes & Noble, NY, 2013)
