Question

Why are principles, laws and axioms useful in science and engineering?

a)	Without principles science and engineering can be unethical

b)	They provide an overarching understanding that can be applied to a wide variety of problems

c)	They make disciplines harder to learn and teach so only top students can master them

d)	They recognize and exploit the commonalities in a class of problems and solutions to facilitate finding solutions

e)	All of the above

f)	a and b only

g)	b and d only

Answer 1

option no g is the right choice which looks more feasible.

now discussing every option one by one

Option no (a) which says about ethicalness of the science and engineering. this is not at all correct. Principles are principles they are universal they can be applied at the problem which is related to sociaty. The effects can be positive or negative both. Ethics is all about right or wrong. Making a dam in the flood effected area is definitely a requirement of the native of those areas but putting in to mind the fact that this dam requires a huge amount of land which is a very important thing for the villege people for there agriculture on which they are dependent. Ethics is an overall approach to solve the problems. Where as for the construction of dam some fundamental prrinciples will be always used.

Now see the option no (c) this totally wrong. THis is right that mental sharpness will be useful in identification of the problems and their solution but it does"nt mean that those principles laws and axioms are made for the sharp people. Thoughts are always variable every person's mental ability is different. Everybody can understand different dimensions of the an object. Only one dimension is not always perfect though it could be predominent.

So option no (b) and (d) are right in all the respect.
