Rudolf Clasius and second law of thermodynamics

I believe that there will always be people to disagree with the ideas being presented and try to prove these theories wrong. Like all of the mathematicians before him, they all took some of their ideas from the great philosopher Aristotle. Clausius's idea originated with steam engines, because they conducted heat into energy. He used the idea of refridgerators to help prove his ideas. There are other scientists/mathematicians from Clausius time period, such as Daniel Farenheit, Anders celsius, and James Joule, that contribute to Clausius's theories. They are all directly related to his study of heat and fire. Clausius concluded that heat is a mixture of different kinds of energies. I think that by Clasius having the second law, that he has improved the other theories that were acknowledged. He conducted numerous experiments and although being challenged by Thomson, he was still successful. I think that without his discovery, then many scientists would find it difficult to conduct experiments.
