2. Definition of Thermodynamics
Thermodynamics is defined as the science of energy.
The name Thermodynamics stems from the Greek words therme (Heat) and dynamics (Power).
Clearly depicting the early efforts to convert heat into power.
Steam power already had many uses - draining water from mines, excavating ports and rivers, forging iron, grinding grain, and spinning and weaving cloth - but it was inefficient.

A Man Who Proved that Proper Blend of Science, Mathematics and Ingenuity is Good Engineering….

4. Definition of Engineering Thermodynamics
Engineering Thermodynamics is the subject that deals with the study of the science of thermodynamics and the usefulness of this science in the design of each & every process, device or system involving the effective utilization of energy and matter for the benefit of mankind.
The Trio of Thermodynamics : Heat, Work & Energy.
Matter playing the role of a House.

5. 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.
Therefore, the deep impression which Classical Thermodynamics made upon me.
It is only physical theory of universal content concerning which I am convinced that ,
within the framework of the applicability of its basic concepts, it will never be overthrown.

6. 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."

7. Thermodynamics beyond Engineering
Human Thermodynamics (HT) is the study of heat and work transformations involved in the processes of human existence.
Psychodynamics : Originated the application of the First Law of Thermodynamics to the realm of conserved conscious and unconscious and mental processes.
Chemical Thermodynamics. Invented by Gibbs.
“You are a big chemical reaction. Everything you say, all that you do, all that you see, decide or remember, think or feel is nothing but the manifestation of the chemical reaction that is you.” – Jim Eadon

15. One Historical Event for Better focus on the Target
In 1893, the Benz Velo became the world's first inexpensive, mass-produced car.
12000 unites were produced.
0.7 hp and 958cc!!!

16. More Close Look at the Target

17. Another Historical Event for Better focus on the Target
The Mercedes 35 HP (German: Mercedes 35 PS) was a radical early car model designed in 1901.
Engine volume: 5,918CC.
The racecar was of a disappointing performance by multiple technical complications and enduring just for few laps.
