To develop upon Nick's excellent 'Sand Pebbles story' about the relevance of levels of understanding,
the following is spewed out . 
The sciences are anchored in mathematics.
Mathematics is anchored in the concept of one. (unity).
Unity is a manmade construct.
Therefore the sciences are nothing more that a manmade means of communicating manmade realities.
All of the above is anchored in philosophy.
If all these anchors are weighing you down ~ consider taking up the following new belief system.
The Irrefutable Theocracy (TIT)
The theory of TIT;
TIT is based on the concept that the world of a newborn is its mother, and specifically her breast. When weaned, the infant searches for replacement beliefs. This is where religions and governments step in with their specific constructs of ideology and faith.
The commandments of TIT;
1/ There is no 'Meaning of Life'.
2/
There is no reason for any more commandments.
All IMHO
Now the helicopter should look very simple.
