Robert Boyle

• 17th-century natural philosopher, chemist,
  physicist, and inventor, also noted for his
  writings in theology.
• Scientific interest in the manufacturing of gas
  produced by the natural decomposition of organic
  matter, was first reported in the seventeenth
  century by Robert Boyle

Unlike most scientists of the day, Boyle did not
seek to discover new things by arguing matters
logically. Instead he was interested in making
observations and drawing conclusions based on
these. It was Boyle who started the practice of
conducting controlled experiments. He used to
publish his experiments while noting down his
practices and the various apparatus that he used.

Inspiring Words Albert Einstein

• When asked what he wished to become, as a young
  man, Nobel Laureate Albert Einstein said,
• "I want to become a useful person, not a
  successful person."
• Asked what he meant by it, the eminent physicist
  replied,
• "A successful person is one who takes from
  society more than what he gives it.
• A useful person is one who gives the society more
  than what he takes from it."

Albert Einsteins Opinion on Best Theory

• A Theory is more impressive or useful
• the greater the simplicity of its premises is,
• the more different kinds of things it relates,
• and the more extended is its area of
  applicability.

The subject, fascinated Hans Albert Einstein

• Hans Albert Einstein was a Swiss-American
  engineer and educator.
• He was an avid sailor, frequently taking
  colleagues and family out for excursions on the
  San Francisco Bay.
• On his many field trips and academic excursions,
  he took thousands of pictures, many of which he
  developed himself and presented as slide shows.

• In tribute to Einstein's lifelong contributions
  to the field, his former graduate students
  published a book of research in his honor in
  1972, Sedimentation Symposium to Honor Professor
  H.A. Einstein.
• In 1988, the American Society of Civil Engineers
  created the Hans Albert Einstein Award to
  recognize outstanding achievements in erosion
  control, sedimentation and/or waterway
  development.

Fluid Flow Everyday of Life Everyones Life

• The earth is 75 covered with water and 100 with
  air.
• The scope of fluid flow is vast and has numerous
  applications in engineering and human activities.
  
• The flow of a river never ceases to go past,
  nevertheless it is not the same water as before.
• Bubbles floating along on the stagnant water now
  vanish and then develop but have never remained.
  
• By Chohmei Kamo, the famous thirteenth century
  essayist of Japan, in the prologue of Hohjohki,
• In this way, the air and the water of rivers and
  seas are always moving.
• Such a movement of gas or liquid (collectively
  called fluid) is called the flow, and the
  study of this is Advanced Fluid Flows.
