refers to concepts dealing with teh (blank) of gravitational and interial mass and to einstein's assertion that the gravitational force as experienced locally is the same as the pseudo force in a non intertial frame of reference
|
equivalence principle
|
|
first galileo expressed this experimentally that the acceleration of a test mass due to gravitation is independent of the amount of mass being accelerated
|
equivalence principle
|
|
It was introduced by Einstein in 1907. This was combined with special relativity to predict that clocks run at different rates in a gravitational potential
|
equivalence principle
|
|
Suggests that gravity is entirely geometrical by nature and doesn't have any extra field associated with it. Einstein's theory of general relativity with the cosmological constant is thought to be the only theory that satisfies this.
Alternative theories include the Brans-Dicke theory |
equivalence principle
|
|
Father Tommaso Caccini denounced his opinions on the motion of the earth - judging them to be heresy - and he went to rome to defend himself.
During this time, he wrote his first work : The Assayer. |

Lost part of his nose in a duel with Manderup Parsbjerg in the Christmas SEason of 1566.
He then became interested in medicine and alchemy and wore a replacement of silver and gold. |
brahe
|
|
de nova stella on a supernova in 1566
he relied on the new technique of prosthaphaeresis - an algorith for approximating products based on trig identities that predates logarithms |

|
treatise consisting of 13 books written in Alexandria in 300 BC.
|
euclid's elements
|
|
second only to the bible in the number of editions published
|
euclid's elements
|
|
it was thought to be influenced by Proclus - a greek mathematician who lived years before the author.
Pythagoras was the source of book I and II. It may have been based on a textbook by Hippocrates of Chios |
euclid's elements
|
|
Theon of Alexandria produced the most popular edition of this until Francois Peyrard's discovery at the Vatican of a manuscript from Theon - the Heiberg manuscript - which is the basis of modern aditions
|
euclid's elements
|
|
EDITIONS
first printed in 1482 Theon - Greek John Dee provided the Mathematical Preface to the first English one by Henry Billingsley |
euclid's elements
|
|
the annotations to the text are called the scholia.
Edna St. Vincent Millay wrote in her sonnet "(Blank) alone has looked on beauty bare" |
euclid
|
|
Dutch philosopher of portuguese and Jewish origin.
he is considered one of the great rationalists of the 17th century philosophy. He opposed Descarte's mind-body dualism. |
spinoza
|
|
he worked as a lens grinder but was eventually excommunicated (cherem) dismissing him from the jewish community
he lived in the school of Franciscu van den Enden. In this time he became oriented with Collegiants, members of a sect towards rationalism. |
spinoza
|
|
he corresponded with Peter Serrarius, a radical protestant and millennarian merchant.
|
spinoza
|
|
his first work = theological-piolitical treatise.
leibniz strongly disagreed with him and published a Refutation of him |
spinoza
|
|
he came up with a solution to the mind-body problem known as neutral monism.
his consequences imagines a god that doesn't rule over the universe by providence but a god that is the deterministic system of which everything is a part. |
spinoza
|
|
Treatise on the Improvement of the Understanding
|
spinoza
|
|
A Treatise on Algebra
Enquiry Concerning the Principles of Natural Knowledge |
whitehead
|
|
He made an address : The Aims of Education
which criticized the formalistic approach of teachers who don't care about culture and self-education he was asked to give The Gifford Lectures at the University of Edinburgh - published as Process and Reality |
whiteheadWhitehad
|
|
built the first practical reflecting telescope and developed a theory of color based on the observation that a prism decomposes white light into many colors.
|
newton
|
|
law of cooling
|
newton
|
|
he wrote
On Color - which he later turned into opticks |
newton
|
|
in Hypohtesis of Light - he posits the existence of the ether to transmit forces between parties.
|
newton
|
|
he communicated his astronomical results to John Flamsteed and Edmund Halley in his De Motu Corporum in Gyrum
which was eventually expanded into his most famous work |
newton
|
|
in its gravitational force, this law was first suggested in 1645 by Ismael Bullialdus.
Coloumb's Law does this between two electrically charged particles |
inverse square law
|
|
when a substance has this property, it has an electrical resistance of exactly zero and no interior magnetic field.
|
superconductivity
|
|
discovered by keike kamerlingh onnes in 1911
|
superconductivity
|
|
the type II of these, a small amount of resistivity appears at temperatures not too far below the nominal superconducting transition when an electrical current is applied in conjunction with a strong magnetic field.
|
superconductivity
|
|
when a superconductor is placed in a weak external magnetic field - the field penetrates the superconductor a small distance - called the London penetration, decaying to zero
|
meissner effect
|
|
sometimes confused with diamagnetism. but this is when the magnetic field is changing, according to Lenz's law.
They are distinct because a superconductor expels all magnetic field not just those that are changing |
meissner effect
|
|
explained by Fritz and Heinz London who showed that the electromagnetic free energy is minimized in the London equation
|
Meissner effect
|
|
the Ginzburg-Landau theory and the BCS Theory graetly impacted this
|
Superconductivity
|
|
One key to step to understanding this was when Meissner and Ochsenfeld discvoered that these expelled applied magnetic fields
|
