From 1876 to 1878 he studied at TU Wien, where he attended lectures on mathematics, physics, and descriptive geometry.
Šourek then went to Czech Technical University in Prague, where he furthered his knowledge of mathematics, physics, and descriptive geometry.
From the years 1893 to 1902, while continuing his professorial duties at Sofia University, he lectured on descriptive geometry at a school for teacher training.
In 1914 his bad health compelled him to resign his professorship at Sofia University and to move to Rome, where he became an unsalaried secretary of the military attaché.
Perhaps his two most important translations into Bulgarian are Alois Strnad's Geometrie pro vyšší třídy reálných gymnázií (Bulgarian title: Геометрия за висшите класове на реалните гимназии, Geometry for upper classes of state gymnasia) and Emanuel Taftl’s textbook Algebra pro vyšší třídy středních škol (Bulgarian title: Алгебра за горните класове на гимназиалните училища, Algebra for upper classes of secondary schools).
