* 1798 – Count Rumford ( Benjamin Thompson ) performs measurements of the frictional heat generated in boring cannons and develops the idea that heat is a form of kinetic energy ; his measurements are inconsistent with caloric theory, but are also sufficiently imprecise as to leave room for doubt.

* 1820 – John Herapath develops some ideas in the kinetic theory of gases but mistakenly associates temperature with molecular momentum rather than kinetic energy ; his work receives little attention other than from Joule

* 1824 – Sadi Carnot analyzes the efficiency of steam engines using caloric theory ; he develops the notion of a reversible process and, in postulating that no such thing exists in nature, lays the foundation for the second law of thermodynamics, and initiating the science of thermodynamics

As discussed in more detail below, Einstein's theory of relativity significantly modifies this view.

Felix Hausdorff ( November 8, 1868 – January 26, 1942 ) was a German mathematician who is considered to be one of the founders of modern topology and who contributed significantly to set theory, descriptive set theory, measure theory, function theory, and functional analysis.

Weber's analysis of modernity and rationalisation significantly influenced the critical theory associated with the Frankfurt School.

But, even though Weber's research interests were very much in line with that school, his views on methodology and the theory of value diverged significantly from those of other German historicists and were closer, in fact, to those of Carl Menger and the Austrian School, the traditional rivals of the historical school.

Finite model theory, which concentrates on finite structures, diverges significantly from the study of infinite structures in both the problems studied and the techniques used.

Early quantum theory was significantly reformulated in the mid-1920s by Werner Heisenberg, Erwin Schrodinger, Max Born, Wolfgang Pauli and their collaborators, and the Copenhagen interpretation of Niels Bohr became widely accepted.

Because that goal is significantly less vacuous than " maximizing utility " and the like, rational choice theory is apt.

According to social identity theory, an important component of the self-concept is derived from memberships in social groups and categories ; this is demonstrated by group processes and how inter-group relationships impact significantly on individuals ' self perception and behaviors.

Liddell Hart also stated that study of Sherman's campaigns had contributed significantly to his own " theory of strategy and tactics in mechanized warfare ", which had in turn influenced Heinz Guderian's doctrine of Blitzkrieg and Rommel's use of tanks during the Second World War.

Sometimes a spinner will bowl leg theory and have seven fielders on the leg side, and will bowl significantly wide of the leg stump to prevent scoring.

In the past, research and clinical studies seemed to corroborate the D < sub > 2 </ sub > receptor blockade theory in which antipsychotic drugs were thought to significantly reduce dopamine activity by blocking the D < sub > 2 </ sub > receptors associated with this neurotransmitter.

By applying those vectors he significantly simplified the calculation and directly obtained all the formulas of the classical theory of secular perturbations.

Similar to Lenin's use of it, left communists, coming from the Communist International themselves started in fact with a theory of decadence in the first place, yet the communist left sees the theory of decadence at the heart of Marx's method as well, expressed in famous works such as The Communist Manifesto, Grundrisse, Das Kapital but most significantly in Preface to the Critique of Political Economy.
