His professors were world-renowned physicist Dimitrios Stroumpos and astronomer Georgios Konstantinos Vouris.

He was exposed to the works of Joseph Liouville, Augustin-Louis Cauchy, Bernard Lamy, and Jacques Charles François Sturm.

Lakon's math textbooks were used in high schools across Greece during the second half of the 19th century.

He presented the idea of motion relative to geometry and discussed the rotation and placement of geometric figures on a plane and in space.

His oldest son was the famous Greek poet Kostas Karthaios (Κώστας Καρθαίος).

His professors in Athens were world-renowned physicist Dimitrios Stroumpos and astronomer Georgios Konstantinos Vouris.

Francis Bacon embraced science while Italy imposed the inquisition on Galileo.

He was exposed to the works of Joseph Liouville, Augustin-Louis Cauchy, Bernard Lamy, and Jacques Charles François Sturm.

He wrote numerous textbooks in the field of physics and mathematics for high school and college education.

He inspired countless students namely famous Greek mathematician John Hazzidakis.

Most of the early college and high school textbooks were translations of French and German scientific advancements.

[11] Éléments de Géométrie written by Adrien-Marie Legendre greatly rearranged and simplified some of the propositions of Euclid's Elements to create a more effective textbook.

He referenced Aristotle's theories, postulates, primary concepts, and the role of axioms.

By the 1880s, Lakon and his student Ioannis Chatzidakis demonstrated their independent development in their textbooks.

The only approved licensed textbooks for High school and college education were written by Lakon and Ioannis Chatzidakis.

He was very active within the scientific community, constantly interacting with his contemporaries in Greece namely Dimitrios Stroumpos and Timoleon Argyropoulos.

[12] Lakon supported the idea that it was impossible to experimentally confirm the indefinite divisibility of matter.

His contemporary Antonios Damaskinos supported the existence of a vacuum between small particles and in space between celestial bodies.

Argyopoulos and Lakon supported the belief that the Aether did not allow for the existence of an absolute vacuum.

He felt it was ambiguous and lacked definitions for certain notions such as equality, excess, and defect.

There was a growing debate among German mathematicians in the 19th century centered around the definition of the plane.

Lakon proved the existence of a surface using Simson line He defined it as a plane.

Lakon presented geometry as a theory of solid bodies using the rotations of straight lines about one axis utilizing the placement and inversion of objects in space.
