THE NAME MILKY WAY

Where does the name "MILKY WAY" came from? I had research the two reasons first, "The Milky Way" is a translation of the Latin Via Lactea, which in turn is derived from Greek (Galaxias) sometimes referred to simply as "the Galaxy", the second reason is "The Ganga of the sky", is the ancient Hindu name for the galaxy as viewed from the Earth, this was called " Akash Ganga ", it is the Hindi name for Milky way.

On the other hand there is said that the Ancient Greek astronomers thought that the Milky Way looked like a river of milk running through the sky, and that's where both "Milky Way" and "Galaxy" come from. Galaxy comes from the Greek word for milk.

In Greek Story the goddesses Athena and Hera (goddesses of wisdom and married life) were out for a walk and came across what seemed to be an abandoned infant. Actually, it was the just-born Herakles [Hercules in Latin], whose mother Hera hated. Athena had planted the child there."Oh, the poor thing!" said Athena. "Come, Hera, give it your breast!" For Hera, being the Great Mother, was constantly in milk even though she herself was seldom pregnant. Anyway, she did so, and Herakles sucked her nipple so powerfully that she yelped with pain and pulled him away. When she did so a spurt of her milk flew into the sky and that's what caused the Milky Way.
MAJOR IMPACT
Francis Bacon who proposed the scientific method is the one that I think made a major impact to science and technology. It is simply because scientific method is accurate when applying to scientific problem and other problem that requires definite answer its accuracy was been proven in early science up to this modern science by numerous discoveries and inventionsthat were very helful and useful. We cannot deny its purposiveness and the truth that through this scientist and his discovered scientific method, Science became productive and proved systematic findings.

SCIENCE IN THE 19TH CENTURY

19th century- appears as a golden age.
Science expanded successfully into new fields of inquiry, combination of math and experiment in physics, application of theory to experiment in chemistry and controlled experimentation in biology.
BREAKTHROUGH IN:
  • iron and steel technology
  • electricity
  • weapons
  • physics and chemistry
  • sociology, psychology and biology

Dalton- English schoolmaster. he proposed that atoms were the smallest indistructible parts of matter.

Mendelev- he began to developed the table of elements which helped in the discovery of new elements.

RADIUM

  • Pierre and Marie Curie announced the discovery of the element radium
  • radium is easily separated
  • existence of the second element, demonstrated by its radioactive properties.

PSYCHOLOGY

  • Sigmund Freud looked for explanation for individual human behavior beyond the National level

BIOLOGY

  • Charles Darwin developed the Hitory of Evolution

DIFFERENCES IN STYLE OF RESEARCH

Progress in PHYSICS

  1. Hans Christian Oersted- electic current produces a magnetic field
  2. Michael Faraday- reverse effect
  3. Joseph Henry- built the 1st powerful electromagnets and invented the electric motor
  4. James Prescott Joule- 1st law of thermodynamics
  5. Wilhelm Roentgen- x-ray
  6. Marie Curie- gave the name radioactive, she and her husband Pierre Curi went on to discover polonium and radium

Progress in CHEMISTRY

  1. Friedrich Wohler- prepared urea in a test tube from inorganic starting materials
  2. Baron Justus Von liebig- chemical fertilizers
  3. Dmitri Mendeleev- systematic and periodic arrangement

Progress in ASTRONOMY

  1. Sir William Herchel- uranus did notb t precisely mve in its expected orbit
  2. Urban J.J. Everrier- neptune

Progress in BIOLOGY

  1. Karl Ernst Von Baer- embryology
  2. Charles Darwin- Origin of Speies
  3. Gregor Mendel- Pattern of inheritance of characteristic from one generation of sweet peas to other.

Progress in MEDICINE

  1. William Morton- anesthetics
  2. Louis Pasteur- methods of immunizing people
  3. Joseph Lister- antiseptic surgery
  4. Walter Reed- yellow fever is caused by a virus carried by a mosquito.

SCIENCE DURING RENAISSANCE PERIOD

ESTABLISHMENTS OF ACADEMIES
  1. Academia dei Lincei in Rome (1603-1630)
  2. Academia del Cimiento in Florante (1657-1667)

  1. Journal Des Savants of Paris (1665)
  2. Aeta Eruditorium of Leipzig (1682)

GREAT TREATISES

  1. Principia Mathematica of Sir Isaac Newton (1687)
  2. Trait de La Lumieres of Christian Huygens (1690)

REMARKABLE SCIENTIST

  • Johan Gutenburg- printing press
  • German Cardinal Nickolas of Cusa- exponent of the value of experiment
  • Niccolas Copernicus- heliocentric theory
  • Leonardo Da Vinci- greatest Artist of his time
  • Andres Vesalius- founder of Modern Human Anatomy

NEW STATUS OF GREEK SCIENCE

  • Simon Stevinus- decimal fraction
  • Johannes kypler- theorized about the movement of planet
  • Rene Descartes- inventor of graph who delivered the existence of GOD
  • Paracelsus- alchemist
  • Francis Bacon- improvised scientific method
  • Isaac newton- discovered the gravity
