aren't we here to answer d cute pikachu's problem and, well, discuss on quantum physics? ghahhaaha

this was what i wrote on the different thread 'energy'
in fact, the truth,
as stated by physicist like stephen hawking,
is as follow:
though we can define some quantities or explain things or define them in terms of more fundamental quantities (e.g. speed in terms of distance and time),
some concepts are so fundamental that any such attempt leads to a circulation definition like that just stated.
to escape from this, we will have to define such quantities 'operationally', which means we describe what they do,rather than what they are. i.e. we can explain how do they operate.
such as mass, we can explain it through the force an object experiences when exposed to gravity, that is, objects of same mass will experience the same force when placed at the same point or in the same strength of gravitational field.
why physics involves maths so much that one can't really understand it without maths?
because the physical world appears to be largely governed by the laws of cause and effect, and maths is used to explain such casual relationship,
and it is used to make prediction and measurement.
every single row of correct maths equation or formula that can be written is a valid representation of certain event in this physical world.
And there are foundational issues like what is time, space, energy etc ...Added on September 10, 2010, 1:24 amwell cute lil pikachu, an addition to my previous second post
