Milestones in Physics: 1543 -- Sun-Centered Universe
“Nicholas Copernicus was the first individual to present a comprehensive heliocentric theory that suggested the Earth was not the center of the universe. His book, De Revolutionibus Orbium Coelestium (On the Revolutions of the Celestial Spheres) was published in 1543, the year he died, and put forward the theory that the Earth revolved around the Sun. Copernicus was a Polish mathematician, physician, and classical scholar - astronomy was something he studied in his spare time - but it was in the field of astronomy that he changed the world. . . . 'Of all discoveries and opinions,' wrote the German polymath Johann Wolfgang von Goethe in 1808, 'none may have exerte a greater effect on the human spirit than the doctrine of Copernicus. The world had scarcely become known as round and complete in itself when it was asked to waive the tremendous privilege of being the center of the universe.” (The Physics Book, by Clifford A. Pickover, Barnes & Noble, NY, 2013)
Famous Dead Guys - William Gilbert, (1544-1603)
Gilbert's De Magnete ("On the Magnet") was published in 1600 and quickly became the standard work throughout Europe on electrical and magnetic phenomena. Europeans were making long voyages across oceans, and the magnetic compass was one of the few instruments that could save them from being hopelessly (and usually fatally) lost. . . He likened the polarity of the magnet to the polarity of the Earth and built an entire magnetic philosophy on this analogy. In Gilbert's animistic explanation, magnetism was the soul of the Earth and a perfectly spherical lodestone, when aligned with the Earth's poles, would spin on its axis, just as the Earth spins on its axis in 24 hours.

Milestones in Physics: 1610 -- Discovery of Saturn's Rings -- Galileo Galilei (1564-1642), Christiaan Huygens (1629-1695), Giovanni Domenico Cassini (1625-1712)
|
“In 1610, Galileo Galilei became the first person to observe Saturn's rings; however, he described them as 'ears'. It was not until 1655 that Christiaan Huygens was able to use his higher-quality telescope and become the first person to describe the feature as an actual ring surrounding Saturn. Finally, in 1675, Giovanni Cassini determined that Saturn's 'ring' was actually composed of subrings with gaps between them. Two such gaps have been carved out by orbiting moonlets, but other gaps remain unexplained. Orbital resonances, which result from the periodic gravitational influences of Saturn's moons, also affect the stability of the rings. Each subring orbits at a different speed around the planet. Today we know that the rings consist of small particles, made almost entirely of water ice, rocks and dust. . . . The particles range in size from a sand grain to the size of a house. The ring structures also have a thin atmosphere composed of oxygen gas. The rings may have been created by the debris from the breakup of some ancient moon, comet, or asteroid. . . . In the 1980's, a mysterious event occurred that suddenly warped the planet's innermost rings into a ridged spiral pattern, 'like the grooves on a vinyl record'. . . . In 2009, scientists at NASA discovered a nearly invisible ring around Saturn that is so large that it would take 1 billion Earths to fill it.” (The Physics Book, by Clifford A. Pickover, Barnes & Noble, NY, 2013)

Windsails
Sailing the ocean no longer requires triple-masted schooners--in fact you can do it on a vessel no larger than a surfboard. What's the secret to designing a windsail that can skim the surface of the sea at 20 miles an hour, yet respond instantly to a sailor's touch?

Milestones in Physics: 1611 -- Kepler's "Six-Cornered Snowflake" -- Johannes Kepler (1571-1630)
“Snow crystals with hexagonal symmetry have intrigued artists and scientists throughout history. In 1611, Johannes Kepler published the monograph "On the Six-Cornered Snowflake," which is among the earliest treatments of snowflake formations that sought a scientific understanding in contrast to a religious one. . . . he considered it more likely that some kind of hexagonal packing of particles, smaller than is ability to discern, could provide an explanation of the marvelous snowflake geometries. Snowflakes (or, more rigorously, snow crystals, given that actual flakes from the sky may consist of many crystals) often begin their lives as tiny dust particles on which water molecules condense at sufficiently low temperatures. As the growing crystal falls through different atmospheric humidities and temperatures, water vapor continues to condense into solid ice, and the crystal slowly obtains its shape. . . . Physicists study snow crystals and their formation partly because crystals are important in applications ranging from electronics to the science of self-assembly, molecular dynamics, and the spontaneous formation of patterns. Since a typical snow crystal contains about 1018 water molecules, the odds are virtually zero that two crystals of typical size are identical. At the macroscopic level, it is unlikely that any two large, complex snowflakes have ever looked completely alike -- since the first snowflake fell on earth.” (The Physics Book, by Clifford A. Pickover, Barnes & Noble, NY, 2013)

Milestones in Physics: 1621 -- Aurora Borealis
Pierre Gassendi (1592-1655),Alfred Angot (1848-1924),
Olof Petrus Hiorter (1696-1750), Anders Celsius (1701-1744)
“. . . Author George Bryson writes, 'Ancient Scandinavians saw the northern lights as the recently departed souls of strong, beautiful women hovering in the air . . . Electric green pierced by neon blue, shocking pink spinning into deep red, shimmering violet fading.' . . . Energetic charged particles streaming from the solar wind of the Sun enter the Earth's atmosphere and are channeled toward the north and south magnetic poles of the Earth. As the particles spiral around the magnetic field lines, they collide with atmospheric oxygen and nitrogen atoms, forcing the atoms into excited states. When the electrons of the atoms return to their lower-energy ground states, they emit a light - for example red and green for oxygen atoms - that is seen in amazing light displays near the Earth's polar regions and that take place in the ionosphere (the uppermost part of the atmosphere, charged by solar radiation). Nitrogen may contribute a blue tinge when a nitrogen atom regins an electron after it has been ionized. When near the North Pole, the light display is called the aurora borealis. The southern counterpart is the aurora australis. . . . it wasn't until 1621 that the term aurora borealis was coined by Pierre Gassendi - French philosopher, priest, astronomer, and mathematician - after Aurora (the Roman goddess of dawn) and Boreas (the Greek name for 'north wind'). In 1741, Swedish astronomers Olof Petrus Hiorter and Anders Celsius suggested that auroras were controlled by magnetic effects after observing fluctuations of compass needles when auroras were in the sky. Today we know that other planets, such as Jupiter and Saturn, have magnetic fields stronger than thos of the Earth; they also have auroras.” (The Physics Book, by Clifford A. Pickover, Barnes & Noble, NY, 2013)
People in Physics - Vincent Rodgers"I was always in competition with my twin brother, to find out who could be the smartest, who knows the most about how everything worked." Vincent and Victor are still competing to learn about the world, but they have chosen different ways of learning. Victor became a chemical engineer, while Vincent became a physicist. “[Victor] wanted to be much more practical with his way of handling things, and I wanted to really learn what was going on in a fundamental level,” Rodgers said. Vincent studies an offshoot of superstring theory, a theory that says the universe's fundamental constituents are tiny vibrating strings. He studies the way gravity works in various conceptions of string theory. He uses mathematics to describe his theories, and he sometimes takes a pen and paper to bed with him at night to make calculations. “It's fun,”Rodgers said. “I think there's some really great stuff [in physics] to play around with.” Vincent Rodgers teaches a class at the University of Iowa called “Physics from Head to Toe,” which studies how physics can apply to the human body. The class talks about how particles cross membranes in cells, how the brain sends electrical signals, and many other ways physics can describe the body.

Milestones in Physics: 1660 – Hooke’s Law of Elasticity
– Robert Hooke (1635-1703), Augustin-Louis Cauchy (1789-1857)
“ . . . In 1660, the English physicist Robert Hooke discovered what we now call Hooke’s Law of Elasticity, which states that if an object, such as a metal rod or spring, is elongated by some distance x, the restoring force F exerted by the object is proportional to x. This relationship is represented by the equation F = -kx. Here, k is a constant of proportionality that is often referred to as the spring constant when Hooke’s Law is applied to springs. Hooke’s Law is an approximation that applies for certain materials, like steel, which are called “Hookean” materials because the obey Hooke’s Law under a significant range of conditions. . . . French mathematician Augustin-Louis Cauchy generalized Hooke’s Law to three-dimensional (3D) forces and elastic bodies, and this more complicated formulation relies on six components of stress and six components of strain. The stress-strain relationship forms a 36-component stress-strain tensor when written in matrix form. If a metal is lightly stressed, a temporary deformation may be achieved by an elastic displacement of the atoms in the 3D lattice. Removal of the stress results in a return of the metal to its original shape and dimensions.” (The Physics Book, by Clifford A. Pickover, Barnes & Noble, NY, 2013)
