Milestones in Physics: 1596 -- Mysterium Cosmographicum
“Throughout his life, German astronomer Johannes Kepler attributed his scientific ideas and motivation to his quest for understanding the mind of God. For example, in his work Mysterium Cosmographicum (The Sacred Mystery of the Cosmos, 1596), he wrote, 'I believe that Divine Providence intervened so that by chance I found what I could never obtain by my own efforts. I believe this all the more because I have constantly prayed to God that I might succeed.' Kepler's initial vision of the universe rested upon his studies of symmetrical, three-dimensional objects known as Platonic solids. . . . Although Kepler's sixteenth-century theory seems strange to us today, he attempted to show that the distances from the planets to the Sun could be found by studying spheres inside these regular polyhedra, which he nested in one another like layers of an onion. . . . In particular, an outer sphere surrounds a cube. Inside the cube is a sphere, followed by a tetrahedron, followed by another sphere, followed by a dodecahedron, followed by a sphere, an icosahedron, sphere, and finally a small inner octahedron. A planet may be imagined as being embedded in each sphere that defines an orbit of a planet.” (The Physics Book, by Clifford A. Pickover, Barnes & Noble, NY, 2013)
Higgs Boson, Key to the Universe, Wins Nobel Prize
(Reuters) - Britain's Peter Higgs and Francois Englert of Belgium won the Nobel Prize for physics on Tuesday [Oct 8, 2013] for predicting the existence of the Higgs boson particle that explains how elementary matter attained the mass to form stars and planets. Half a century after their original work, the new building block of nature was finally detected in 2012 at the European Organization for Nuclear Research (CERN) centre's giant, underground particle-smasher near Geneva. The discovery was hailed as one of the most important in physics. http://www.reuters.com/article/2013/10/08/us-nobel-physics-idUSBRE9970B620131008

Milestones in Physics: 1600, De Magnete, William Gilbert (1544-1603)
“William Gilbert's book De Magnete, published in 1600, is considered to be the first great work on physical science to be produced in England, and much of European science had its roots in Gilbert's initial theories and fondness for experiments. A personal physician to Queen Elizabeth I, Gilbert is one of the important fathers of the science of electricity and magnetism. . . . In his research in terrestrial magnetism, Gilbert created a spherical lodestone, about a foot (0.3 meters) in diameter, which he called a terrella (little Earth). By moving a small magnetic needle on a pivot around the terrella's surface, he showed that the terrella had a North and South Pole, and that the needle dipped as it neared a pole, which mimics the dipping of compass needles on the Earth as they approach the poles. He postulated that the Earth was like a giant lodestone. . . . William Gilbert suggested that the Earth generated its own magnetic field. Today we know that a magnetosphere, represented [below] as a violet bubble around the Earth, is formed when charged particles from the sun interact with and are deflected by the Earth's magnetic field.” (The Physics Book, by Clifford A. Pickover, Barnes & Noble, NY, 2013)
Famous Dead Guy - Robert HookeBorn: 18 July 1635 in Freshwater, Isle of Wight, England
Died: 3 March 1703 in London, England Hooke was never a person who did one thing at a time, indeed he seemed at his best when his mind was jumping from one idea to another. At the same time that he was working on the air pump he was also thinking about clocks and how they could be used in determining the longitude at sea. Realizing the weakness of the pendulum clock in keeping time on a ship which was pitching and tossing, he wondered about the "... use of springs instead of gravity for making a body vibrate in any posture." Rather than the balance wheel being controlled by a pendulum which in turn operated through gravity, he reasoned that controlling the balance wheel with a spring would have huge advantages for a portable timekeeper that one might carry around or one which would have to continue to keep the correct time on a ship. . . In 1660 he discovered an instance of Hooke's law while working on designs for the balance springs of clocks. However he only announced the general law of elasticity in his lecture Of Spring given in 1678. From: http://www-groups.dcs.st-and.ac.uk/~history/Biographies/Hooke.html |

“Physicist Brian Greene writes, 'The invention of the telescope and it subsequent refinement and use by Galileo marked the birth of the modern scientific method and set the stage for a dramatic reassessment of our place in the cosmos. A technological device revealed conclusively that there is so much more to the universe than is available to our unaided senses.' . . . In 1608, the German-Dutch lensmaker Hans Lippershey may have been the first to invent the telescope, and a year later, the Italian astronomer Galileo Galilei constructed a telescope with about a three-fold magnification. . . . Although the early telescopes were designed to observe remote objects using visible light, modern telescopes are a range of devices capable of utilizing other regions of the electromagnetic spectrum. Refracting telescopes employ lenses to form an image, while reflecting telescopes use an arrangement of mirrors for this purpose. Catadioptric telescopes use mirror and lenses. . . . Astrophysicist Kenneth Lang writes in Science, '. . . The search for the unseen has resulted in many important unexpected discoveries, including Jupiter's four large moons, the planet Uranus, the first asteroid Ceres, the large recession velocities of spiral nebulae, radio emission from the Milky Way, cosmic X-ray sources, Gamma-Ray Bursts, radio pulsars, the binary pulsar with its signature of gravitational radiation, and the Cosmic Microwave Background radiation.'” (The Physics Book, by Clifford A. Pickover, Barnes & Noble, NY, 2013)

People in Physics - Melanie Lott One dancer and physicist has set out to explain how dancers maintain their balance while doing one of the most common movements in dance, the pirouette.
Melanie Lott has successfully merged two disciplines, art and science, by observing an art form and explaining its beauty using science. "The physics of dance is way outside the box," Lott said and she is one scientist who didn’t compromise her passions for her studies. "Follow your passion and don’t be afraid to try something outside the box." Lott lives her life by her own advice.

Words of Wisdom: When everything is coming your way, you're in the wrong lane.
“Snell's Law concerns the bending, or refracting, of light and other waves . . . as they travel through the air and pass into another material, such as glass. When the waves are refracted, the experience a change in the direction of propogation due to a change in their velocities. . . . The law is expressed as n1sin(θ1) = n2sin(θ2). Here, n1 and n2 are the refractive indices of media 1 and 2. The angle between the incident light and a line perpendicular to the interface between media is call the angle of incidence (θ). The light ray continues from medium 1 into medium 2, leaving the boundary between the media at an angle of θ2 to a line that is perpendicular to the boundary. This second angle is known as the angle of refraction. . . . When a beam of light is transmitted from a material with high index of refraction to one of low index, the beam can, under some conditions, be totally reflected. This optical phenomenon is often called total internal reflection, and it occurs when light is refracted at a medium boundary to such an extent that it is reflected back. This phenomenon is observed in certain opticval fibers in which the light enters at one end and remains trapped inside until it emerges from the other end. . . . Snell's Law was discovered independently by various investigators over the centuries but was named after the Dutch astronomer and mathematician, Willebrord Snellius.” (The Physics Book, by Clifford A. Pickover, Barnes & Noble, NY, 2013)
Famous Dead Guy - Lóránd Baron von Eötvös
Born: 27 July 1848 in Pest (now part of Budapest), Hungary
Died: 8 April 1919 in Budapest, Hungary
The achievement of Eötvös in the use of his instrument are threefold. By developing the complete theory of the Eötvös balance, he was able to push its sensitivity to such a point that it took decades to devise methods for exceeding his precision. It is only proper to mention that the high degree of precision he achieved was not due solely to the design of the instrument but depended also on the unparalleled skill he displayed in using it. The other two accomplishments encompassed the clear recognition of the very important applications of the balance: geophysical exploration and the equivalence of gravitational and inertial mass. In both cases the recognition was followed by intense work proving his insight.

Milestones in Physics: 1644 – Conservation of Momentum – Rene’ Descartes (1596-1650)
“Since the time of the ancient Greek philosophers, humans have wondered about the first great question of physics: How do things move?” The conservation of momentum, one of the great laws of physics, was discussed in an early form by philosopher and scientist Rene’ Descartes in his Principia Philosophiae (Principles of Philosophy), published in 1644. In classical mechanics, linear momentum P is defined as the product of the mass m and velocity v of an object, P = mv, where P and v are vector quantities having a magnitude and direction. For a “closed” (i.e. isolated) system of interacting bodies, the total momentum is conserved. . . . Angular momentum is a related concept that concerns rotating objects.” (The Physics Book, by Clifford A. Pickover, Barnes & Noble, NY, 2013)
People in Physics - Mildred "Millie" DresselhausBrought up in a poor suburb of the Bronx, the young Millie Dresselhaus went to some of the worst schools in New York City. "Things weren't looking to well for me, I was born in the depression - we were one of the many families on welfare". After graduating from Hunter College, Millie was awarded a Fulbright Fellowship which allowed her to spend a year at the Cavendish Laboratory, Cambridge University from 1951- 1952. She received her master's degree at Radcliffe College in 1953. After receiving her PhD, with a thesis on superconductivity 1958, Professor Dresselhaus began her career at the Lincoln Laboratory, where she studied magneto-optics in semiconductors, and carried out a series of experiments which led to a fundamental understanding of the electronic structure of semi-metals, especially graphite. She is currently an Institute Professor of Electrical Engineering and Physics at MIT. With the advent of lasers in the 1960s, Professor Dresselhaus was among the first to use lasers for magneto-optics experiments. These laser studies were the stepping stones to her entry into the field of Raman spectroscopy many years later. Commenting on her research career Professor Dresselhaus says, "If I had never gotten into physics I think I would have gone into school teaching - my entire career I've been very involved with students".
