What is this Physical Science ?

• The Fort of thermo-fluid sciences rests on three pillars:

– Fluid mechanics,

– Thermodynamics

– Heat transfer.

• Fluid mechanics’ principles are involved in open system thermodynamics processes.

• They play a primary role in every convective heat transfer problem.

Hans Albert Einstein (May 14, 1904 – July 26, 1973)

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 Einstein`s 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.

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.
