    Paul Hewitt's Conceptual Physics


    docClientStream.cls (215×315)

    "Paul G. Hewitt, former boxer, uranium prospector, signpainter, and cartoonist began college at the age of 28 and fell in love with physics. His name is synonymous with Conceptual Physics to physics educators everywhere.  Before the advent of Professor Hewitt's textbook of the same name, physics was traditionally taught primarily as applied mathematics — geared to students with high math and science aptitudes. As such, any serious study of physics was out of the educational mainstream for most students. Hewitt's conceptual approach changed all this.  By translating the central concepts of physics from mathematical language to common English, and by explaining physics rather than proclaiming physics, and by extensive use of analogies as a teaching tool, Hewitt brought physics into the educational mainstream. His textbook, the leading physics textbook for nonscientists since 1971, has changed the way physics is taught to both non-science and science majors as well.

      In recognition of Hewitt's achievements, the American Association of Physics Teachers honored him in 1982 with their Millikan Award — the once-per-year prestigious prize for outstanding contributions to physics teaching. Prior to this, Hewitt produced a film with animator Steve Smith, Relativistic Time Dilation, which won first prize for science at the 1977 American Educational Film Festival. Hewitt is presently a column editor for The Physics Teacher, the monthly magazine of the American Association of Physics Teachers. "

    Neil deGrasse Tyson was born and raised in New York City where he was educated in the public schools clear through his graduation from the Bronx High School of Science. Tyson went on to earn his BA in Physics from Harvard and his PhD in Astrophysics from Columbia.

    Tyson’s professional research interests are broad, but include star formation, exploding stars, dwarf galaxies, and the structure of our Milky Way.

    Tyson is the recipient of twenty honorary doctorates and the NASA Distinguished Public Service Medal, the highest award given by NASA to a non-government citizen.

    Einstein's Theory of General Relativity


    Theory of General Relativity


    Einstein's theory of general relativity predicted that the space-time around Earth would be not only warped but also twisted by the planet's rotation. Gravity Probe B showed this to be correct.

    Aristotle (384-322 BCE)



    "The Greek philosopher Aristotle proposed that the heavens were literally composed of 55 concentric, crystalline spheres to which the celestial objects were attached and which rotated at different velocities (but the angular velocity was constant for a given sphere), with the Earth at the center... Although Aristotle was not a scientist, it is important to note that he did point out that the Earth had to be sphere since its shadow was always circular. This was in fact a key scientific insight. It allowed Eratosthenes around 200 BC to calculate the circumference of the Earth..."



    Ptolemy (140 CE)

    ancient Greek astronomer, geographer, and mathematician who lived in Alexandria, Egypt during the Helenistic period and considered the Earth the center of the universe 


    Copernicus (1473-1543)

    "In the early 1500s, when virtually everyone believed Earth was the center of the universe, Polish scientist Nicolaus Copernicus proposed that the planets instead revolved around the sun."



    Galileo (1564-1642)

    "Galileo Galilei (1564-1642) was a Tuscan (Italian) astronomer, physicist, mathematician, inventor, and philosopher...in 1609 he built his first telescope and began making observations. The following year he published his first results, where he described the highlands and "seas" of the Moon, four of Jupiter's largest moons, and many newly discovered stars. He also discovered the phases of Venus and sunspots, thereby confirming that the Sun rotates, and that the planets orbit around the Sun, not around the Earth. "


    Kepler (1571-1630)

     "Johannes Kepler was a German mathematician and astronomer who discovered that the Earth and planets travel about the sun in elliptical orbits. He gave three fundamental laws of planetary motion."

    "Newton, Sir Isaac (1642-1727), mathematician and physicist, one of the foremost scientific intellects of all time...Newton has been regarded for almost 300 years as the founding examplar of modern physical science, his achievements in experimental investigation being as innovative as those in mathematical research."  



    William Herschel (1738-1822)

     "Sir William Herschel was a German-born British astronomer and composer, who is widely credited as the founder of sidereal astronomy for observing the heavenly bodies. He found the planet Uranus and its two moons, and formulated a theory of stellar evolution. Knighted in 1816, Herschel was also the first astronomer to suggest that nebulae are composed of stars."



    Edwin Hubble (1889-1953)
