The answer is:to a certain distance from the nucleus, the electron probability is the same in all directions.This means that the orbital s has spherical symmetry, in other words, does not depend on the angle.To solve the Schrödinger equation for the hydrogen atom the solution is divided into parts. A part that we call the radial of this part depends on the radius( hence the name), the other is called the angular part, and this part depends on the angle.For each s orbital of the angular part of the equation is:As you can see is constant, does not depend on the angle. It may sound stupid that we call this equation an angular part when it does not depend on the angle, but for other orbitals, this equation contains periodic functions ( sine and cosine) this is the reason why the p orbital has that strange form.You can see all the equations in this link: http://chemistry.bd.psu.edu/jircitano/412ch2a.pdf
