I decided to start 'studying' engineering about two years ago on the wikipedia. man that site is awesome! the way i see it, there are different ways to approach engineering, along with new ways of doing the maths for everyone. but, let's start my 'class' with the basics of engineering - 'what is engineering?'
Engineering is when you get a machine to do things for you. think of your body as a machine and your heart as the engine, pumping blood throughout the body. you want it to pump more blood with less fuel or food taken to do so. this means that things get better all the time.
Basically, you want to observe that engineering is about energy changing forms. if kinetic energy and potential energy are understood, then there should be a solid foundation for this 'field.'
You will also learn a little bit about physics in engineering, as mass has boiling points and conductivity. the thing is that they go into such detail for the degree that you never use the things you learn about! think of it now, do you really need to know field theory to work an engine or split an atom?
I will continue after you ask specific questions, that i will be glad to answer, that is, if you have any. otherwise, i will just continue to unravel the working of the universe at a rather slow pace, step by step, okay?
