Question: Which one for the first thinkers to form Free will in antiquity was also well-known for formulation of an atomic theory of the universe?

Context paragraphs:
Atomism (social): Atomism or social atomism is a sociological theory arising from the scientific notion "atomic theory", coined by the ancient Greek philosopher Democritus and the Roman philosopher Lucretius.  In the scientific rendering of the word, atomism refers to the notion that all matter in the universe is composed of basic indivisible components, or atoms.  When placed into the field of sociology, atomism assigns the individual as the basic unit of analysis for all implications of social life.  This theory refers to "the tendecy for society to be made up of a collection of self-interested and largely self-sufficient individuals, operating as separate atoms".  Therefore, all social values, institutions, developments and procedures evolve entirely out of the interests and actions of the individuals who inhabit any particular society.  The individual is the ‘atom’ of society and therefore the only true object of concern and analysis.

Generalized-strain mesh-free formulation: The generalized-strain mesh-free (GSMF) formulation is a local meshfree method in the field of numerical analysis, completely integration free, working as a weighted-residual weak-form collocation.  This method was first presented by Oliveira and Portela (2016), in order to further improve the computational efficiency of meshfree methods in numerical analysis.  Local meshfree methods are derived through a weighted-residual formulation which leads to a local weak form that is the well known work theorem of the theory of structures.  In an arbitrary local region, the work theorem establishes an energy relationship between a statically-admissible stress field and an independent kinematically-admissible strain field.  Based on the independence of these two fields, this formulation results in a local form of the work theorem that is reduced to regular boundary terms only, integration-free and free of volumetric locking.

Félix Archimède Pouchet: From 1828 he was director of the Rouen Jardin des Plantes.  Later, in 1838, he became professor at the School of Medicine at Rouen.  His major scientific work "Hétérogénie" was published in 1859.  He also wrote a layperson's encyclopedia "The Universe", published in 1870, which gives an overview of the sciences, but in which Pouchet ridicules Louis Pasteur's theories (calling them panspermism) and atomic theory.

Jean Gerson: Jean Charlier de Gerson (13 December 1363 – 12 July 1429) was a French scholar, educator, reformer, and poet, Chancellor of the University of Paris, a guiding light of the conciliar movement and one of the most prominent theologians at the Council of Constance.  He was one of the first thinkers to develop what would later come to be called natural rights theory, and was also one of the first individuals to defend Joan of Arc and proclaim her supernatural vocation as authentic.

Democritus: Democritus ( ; Greek: Δημόκριτος , "Dēmókritos", meaning "chosen of the people"; c. 460 – c. 370 BC ) was an influential Ancient Greek pre-Socratic philosopher primarily remembered today for his formulation of an atomic theory of the universe.

Buddhist atomism: Buddhist atomism is a school of atomistic Buddhist philosophy that flourished on the Indian subcontinent during two major periods .  During the first phase, which began to develop prior to the 4th century BCE, Buddhist atomism had a very qualitative, Aristotelian-style atomic theory.  This form of atomism identifies four kinds of atoms, corresponding to the standard elements.  Each of these elements has a specific property, such as solidity or motion, and performs a specific function in mixtures, such as providing support or causing growth.  Like the Hindus and Jains, the Buddhists were able to integrate a theory of atomism with their logical presuppositions.

Relativistic quantum mechanics: In physics, relativistic quantum mechanics (RQM) is any Poincaré covariant formulation of quantum mechanics (QM).  This theory is applicable to massive particles propagating at all velocities up to those comparable to the speed of light "c", and can accommodate massless particles.  The theory has application in high energy physics, particle physics and accelerator physics, as well as atomic physics, chemistry and condensed matter physics.  "Non-relativistic quantum mechanics" refers to the mathematical formulation of quantum mechanics applied in the context of Galilean relativity, more specifically quantizing the equations of classical mechanics by replacing dynamical variables by operators. "Relativistic quantum mechanics" (RQM) is quantum mechanics applied with special relativity, but not general relativity.  Although the earlier formulations, like the Schrödinger picture and Heisenberg picture were originally formulated in a non-relativistic background, these pictures of quantum mechanics also apply with special relativity.

Archaeosporales: Archaeosporales is an order of fungi best known as arbuscular mycorrhiza to vascular land plants (Tracheophyta).  but also form free living endocyte symbioses with cyanobacteria.  The free living forms have a Precambrian fossil record back 2.2 Ga, well before evolution of Tracheophyta.

Free will in antiquity: Free will in antiquity was not discussed in the same terms as used in the modern free will debates, but historians of the problem have speculated who exactly was first to take positions as determinist, libertarian, and compatibilist in antiquity.  There is wide agreement that these views were essentially fully formed over 2000 years ago.  Candidates for the first thinkers to form these views, as well as the idea of a non-physical "agent-causal" libertarianism, include Democritus (460–370), Aristotle (384–322), Epicurus (341–270), Chrysippus (280–207), and Carneades (214–129).

3form: 3form Free Knowledge Exchange is one of the earliest examples of human-based computation and human-based genetic algorithm (Kosorukoff, 1998).  It uses both human-based selection and three types of human-based innovation (contributing new content, mutation, and recombination), in order to implement collaborative problem-solving between humans.  However, on May 8 2016 3 form was down due to technical issue.
