It's the same as Morrowind except for dual casting. It's the same as many fantasy stories in other media.
OP, there are rules to magic use just as there are rules to technology use. As Farengar points out, magic is a form of energy that can be controlled by those with the will and ability to do so. Part of the rules for Tamriel is that weaving the hands in certain ways allows the caster to control the flow of energy in order to cast a spell.
Likewise, the shouts require the use of the voice. You'll notice that Ulfric is muffled while he is a prisoner at the beginning of the game. You'll notice that your character's hands are bound and you cannot do anything, including casting spells or opening doors, picking up objects, etc.
In other stories, magic may require drawing symbols on the surface of something (e.g., Star Ocean).
These types of rules for magic use are based on real life stories, legends, etc from various cultures throughout the world. If you don't care for the rules for Tamriel, you may not want to play a mage in that world.
For myself, I am annoyed by the lack of wands. I just have to accept it if I want to play. I still don't like it, though.
