I read a book about Numerical Methods and I found that it is very interesting.

Why does numerical method always be taught with engineering?

I think it is quite useful in normal life.

Hmmm, depends on your definition of normal life, but in any case I've found lots of numerical methods (particularly in relation to PDEs) most interesting ... and usable, analytical stuff sucks if you need to do something real life.

In engineering you usually have particularly complex analytical problems to model, and these often have no (or at least a particularly complex) solution. Using numerical methods to give a very good approximation for the solution of these models is all the engineer requires.

I had a option for numerical methods module this year. but i stayed away. cos i had a look at the topics taught, and it was mostly stuff that i could learn by myself

Probably a wise choice ... most of the basic stuff is pretty simple ... once stuff like nonlinearities etc. stuff begin to surface that are out of reach of other means & specific to numerics then its more than worthwhile.

How did Newton have his interests in these engineering?
