	Avagadro's constant, 6.02214129 x 10^23		Avagadro's constant, 6.02214129 x 10^23, was never calculated by Avagadro himself, but because Avagadro is eventually given the title of the founder of the atomic-molecular theory, the constant required for mole-atom conversion was named after Avagadro in 1911 by nobel prize winner Johann Josef Loschmidt.

	Despite Avagadro's (correct) interpretation of molecules and their properties, his work was not widely durring his lifetime. His work largely conflicted with more well known scientists at that time, such as Dalton and Jöns Jacob Berzelius, and was only accepted 4 years after his death in 1856, when a scientist named Stanislao Cannizzaro brought Avagadro's law to light explaining recurring exceptions that occurr at certain temperatures.

The reason why Lussac's experiment produced those results is because the number of molecules decreases as the chemical reaction takes place between hyrogen and oxygen gases. This statement will become known as Avagadro's Law. Because of this, he was one of the first scientists recognize that elements can exist as molecules instead of strictly the atom.

	'''Amadeo Avagadro''' (Lorenze Romano Amedeo Carlo Avagadro, conte di Quaregna e Cerreto) was born on August 9, 1776 in Turin, Italy to a ~~well-renown lawyer family known as the Piedmont family~~. He married Felicita Mazzé in 1818 when Avogadro was aged 42 and raised a family with six sons.		'''Amadeo Avagadro''' (Lorenze Romano Amedeo Carlo Avagadro, conte di Quaregna e Cerreto) was born on August 9, 1776 in Turin, Italy to his father Filippo, a magistrate and senator, and his mother Anna Vercellone, a noblewoman of noblewoman. Avagadro married Felicita Mazzé in 1818 when Avogadro was aged 42 and raised a family with six sons.

	Avogadro had initially started going to law school after his father's request and tradition, but soon after he was inspired to pursue a new path and committed his life to mathematics, physics, and chemistry. After finishing with a doctorate of ecclesiastical law in 1796, he privately began studying physics, and in 1806 he began teaching science and mathematics at the Academy of Sciences of Turin. Three years later he became a professor at the Royal College of Vercelli, but because of civil unrest the university was shut down and forced Avogadro to lose his chair position, only to regain his chair back in 1834. Avogadro died on July 9, 1856.

	~~===A Mathematical Model===~~

	~~In order to find the potential difference between two locations, we use this formula <math> dV~~ = -\left(E_xdx + E_ydy + E_z*dz\right) </math>, where '''E''' is the electric field with components in the x, y, and z directions. Delta x, y, and z are the components of final location minus to the components of the initial location.		=Scientific Contributions=
			Avagadro is most known for his work
	~~===A Computational Model===~~

	~~How do we visualize or predict using this topic. Consider embedding some vpython code here [https://trinket.io/glowscript/31d0f9ad9e Teach hands-on with GlowScript]~~

	~~=Simple Example=~~
	~~[[File:pathindependence.png]]~~

	In this example, the electric field is equal to <math> E = \left(E_x, 0, 0\right)</math>. The initial location is A and the final location is C. In order to find the potential difference between A and C, we use <math>dV = V_C - V_A </math>.

	~~Since there are no y and z components of the electric field, the potential difference is <math> dV = -\left(E_x\left(x_1 - 0\right) + 0\left(-y_1 - 0\right) + 00\right) = -E_xx_1</math>~~

	~~[[File:BC.png]]~~

	Let's say there is a location B at <math> \left(x_1, 0, 0\right) </math>. Now in order to find the potential difference between A and C, we need to find the potential difference between A and B and then between B and C.

	~~The potential difference between A and B is <math>dV = V_B - V_A = -\left(E_x\left(x_1 - 0\right) + 00 + 00\right) = -E_xx_1</math>.~~

	~~The potential difference between B and C is <math>dV = V_C - V_B~~ = ~~-\left(E_x0 + 0\left(-y_1 - 0\right) + 0*0\right) = 0</math>.~~

	~~Therefore, the potential difference A and C is <math>V_C - V_A = \left(V_C - V_B\right) + \left(V_B - V_A\right) = E_x*x_1 </math>, which~~ is ~~the same answer that we got when we did not use location B.~~
