There is a lot of engineering and physics that does not make sense to an untrained person.
Do you understand how an aircraft flies?
How radio or television work?
What the sound barrier really is?
How you can talk when traveling faster than sound?
Why ice floats?
Why twice as much power does not make you go twice as fast?
Why twice as much power does not use twice as much fuel?
Why if you are going twice as fast it takes 4 times the distance to stop?
If an aircraft on a conveyor belt can take off
AFF is full of engineers and other trained professionals. These argument has been fought many times.
If you do not understand the maths or physics involved then a lot of things seem very contradictory.
If you really want to understand it then google is you friend.
But remember that often what you see on TV is written and/or read by people who really have no idea whatsoever and more than often are pushing an agenda.
Look here for more info.
