Here are some of the books that he wrote:
Baroulkos
Berlopoeica (in Greek and Roman Artillery, Technical Treatises, 1971)
Catoptrica (in Latin)
Chieroballistra (in Greek and Roman Artillery; Technical Treatises, 1971)
Definitions?
Dioptra (partical English translation, 1963)
Eutocuis
Geometrica?
Mechanica (3 volumes, in Arabic)
Metrica (3 volumes)
Peri Automatopoitikes (Automata, 1971)
Peri Metron (also called Mensurae)
Pneumatica (2 volumes: The Pneumatica of Hero Of Alexandria, 1851)
Stereometrica
As you can tell, his works ranged from Greek to Latin to Egyptian. Something interesting about one of his books, Metrica is it was lost until the end of the century. Scholars knew of its existence only threw one of his other books, Eutocuis. In 1894, historian Paul Tannery discovered a fragment of the book in Paris. In 1896, R. Schone in Constanitinpole found a copy. That is how Metrica was found. This book is the most famous book that Hero wrote. It consists of 3 books, which calculate area and volume, and their divisions.
Not only did Hero write books he is also famous for find the formula of the area of a triangle. Well finding the area of the triangle is not the only thing that he did, he also figured out the area of an orbitary quadrilaterial, and the area of a cyclic quadrilateral.
The first and most famous formula is the area of a triangle. The formula of a triangle may be Archimedes?s (the famous Greek inventor, but its presentation and popularization is credited to Hero. The formula is:
? A=the square-root of s(s-a)(s-b)(s-c)
The area (A) of the triangle can be computed if you know the length of one side of the triangle (a,b,c). The perimeter (2s) of the triangle is ?a+b+c? with being the semiperimter.
The second formula that Hero came up with is useful for determining the area of an orbitary quadrilateral. The formula is:
? A=the square-root of (s-a)(s-b)(s-c)(s-d)-abcd cos to the second o?
This means a, b, c, and d are the sides of the quadrilateral, 2s is the perimeter (a + b + c + d), and o is half of the sum of 2 opposite angles.
The third formula is the area of a cyclic quadrilateral (which means a quadrilateral can be inscribed in a circle. The formula is:
? ? A= the square-root of (s-a)(s-b)(s-c)(s-d)
Which means the A can be found from the length of the sides of he quadrilateral, where 2s is the perimeter, s is semiperimeter, and a, b, c, and d are the four sides.

He specialized in the field of mechanics mathematics and physics representing the work of the hellenistic tradition in science . the vending machine was the brainchild of heron; the idea of inserting a coin in a machine for it to perform a certain function was mentioned in a book mechanics and optics.
