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: Circa 13.7 Billion BC - Big BangAstrophysicist Stephen Hawking has estimated that if the rate of the universe's expansion one second after the Big Bang had been smaller by even one part in a hundred thousand million millionths, the universe would have re-collapsed and no intelligent life could have evolved.

Milestones in Physics: 30,000 B.C. - Atlatl
At various locations around the world, ancient cultures discovered the physics of killing through the use of an ingenious device called the atlatl. The tool resembles a wooden rod or board with a cup or spur at one end, and it makes use of leverage and other simple physical principles to enable users to hurl a large arrow at a target with a tremendous range (over 100 meters) and at speeds exceeding 92 miles per hour. (The Physics Book, by Clifford A. Pickover, Barnes & Noble, NY, 2013) The modern adaptation of this weapon is used to launch tennis balls for dogs at parks.
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. - Baghdad Battery
"In 1800, Italian physicist Alessandro Volta invented what has been traditionally considered to be the first electric battery when he stacked several pairs of alternating copper and zinc discs separated by cloth soaked in salt water. When the top and bottom of the pile were connected by a wire, an electric current began to flow. However, the discovery of certain archeological artifacts may suggest batteries predate this discovery by more than a millennium . . . In 1938, while in Baghdad, German archeologist Wilhelm König discovered a five-inch-long clay jar containing a copper cylinder that surrounded an iron rod. The jar showed signs of corrosion and seemed to have once contained a mild acid, such as vinegar or wine . . . Subsequent researchers have demonstrated that replicas of the Baghdad Battery do indeed produce electrical current when filled with grape juice or vinegar . . . König dated [the jars] to around 250 B.C. to A.D. 224, while others have suggested a range of A.D. 225-640." (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: 250 B.C. – Archimedean Screw“Archimedes,
the ancient Greek geometer, is often regarded as the greatest mathematicion and
scientist of antiquity and one of the four greatest mathematicians to have
walked the earth . . . The invention of the water snail, or Archimedean screw,
to raise water and help irrigate crops was attributed to Archimedes by the
Greek historian Diodorus Siculus in the first century B.C. The Roman engineer Vitruvius gives a detailed
description of its operation for lifting water, which required intertwined
helical blades. In order to lift water,
the bottom end of the screw is immersed in a pond, after which the act of
rotation the screw raises water from the pond to a higher elevation . . . an
Archimedean screw the diameter of a pencil eraser is used in a Hemopump cardiac
assist system that maintains blood circulation during heart failure, coronary
bypass surgery, and other surgical procedures.“

Milestones in Physics: 212 B.C. – Archimedes' Burning Mirrors
“In 212 B.C., Archimedes is said to have made a 'death ray' consisting of a set of mirrors that focused sunlight on Roman ships, setting them afire. Various individuals have tried to test the practical use of such mirrors and declared their use to have been unlikely. However, mechanical engineer David Wallace of MIT encouraged his students in 2005 to build an oak replica of a Roman warship and focus sunlight on it, using 127 flat mirrors, each with an edge one foot (o.3m) in length. The ship was about 100 feet (30m) away. After ten minutes of exposure to the focused light, the warship burst into flames! . . . However, while it is possible to set a ship afire with mirrors, this task would have probably been very difficult for Archimedes if the ships were moving." (The Physics Book, by Clifford A. Pickover, Barnes & Noble, NY, 2013)

Milestones in Physics: 50 A.D. – Hero’s Jet Engine
“The history of modern rockets can be traced back through countless experiments to the ancient Greek mathematician and engineer Hero of Alexandria, who invented a rocket-like device called an aeolipile that used steam for propulsion. Hero’s engine consisted of a sphere mounted on top of a kettle of water. A fire below the kettle produced steam that traveled through pipes into the sphere. Steam escaped through two bent tubes on opposite sides of the sphere, providing sufficient thrust so that the sphere would rotate. Because of friction in the bearings, Hero’s engine does not spin increasingly fast but achieves a steady-state speed. . . . Jet and rocket engines rely on Newton’s Third Law of Motion, which states for every action (force in one direction) there is an equal and opposite reaction (force in the opposite direction).” (The Physics Book, by Clifford A. Pickover, Barnes & Noble, NY, 2013)

Milestones in Physics: 1132 -- Cannon
“The cannon, which generally fires heavy projectiles using gunpowder, focused Europe's most brilliant minds on questions regarding the forces and laws of motion. 'Ultimately it was the effects of gunpowder on science rather than on warfare that were to have the greatest influence in bringing about the Machine Age,' writes historian J.D. Bernal. 'Gunpowder and cannon not only blew up the medieval world economically and politically; they were major forces in destroying its system of ideas.' Author Jack Kelley remarks, 'Both gunners and natural philosophers wanted to know: What happens to the cannonball after it leaves the barrel of the gun? The search for a definitive answer took four hundred years and required the creation of entirely new fields of science.' . . . In the 1500's, it was realized that gunpowder produced a large volume of hot gas that exerted pressure on the cannon ball. Italian engineer Niccolò Tartaglia assisted gunners in determining that an elevation of 45 degrees gave a cannon the longest shot (which we know today is only an approximation, due to the effects of air resistance). Galileo's theoretical studies showed that gravity constantly accelerated the fall of a cannonball, producing an idealized trajectory in the shape of a parabolic curve, which every cannonball traces regardless of its mass or initial firing angle.” (The Physics Book, by Clifford A. Pickover, Barnes & Noble, NY, 2013)
Quantum Dots and Cells Probe that cell! What's it doing? Can we control it? Yes we can! Thanks to quantum dots and the amazing research done by Dr. Lin's and Dr. Rieke's research groups at the University of Washington. Their groups have shown experimentally that quantum dots can be used to stimulate cells, to probe them, and to trigger neuron firing with light! And all of this probing and switching is done without altering the cell genetically or chemically. Read the full story at the document to the right.
