Today, my lecturer asked us to define physics. No one give a very obvious and correct answer to the lecturer. Can anyone here give me the best defination of the meaning of physics?? Thanks
Physics is the mathematical study of all conceivable universes. A universe is a mathematical model that describes spacetime, matter, energy and their interactions. Think of each model universe as filling one page in the atlas of all possible universes.alex fregol said:Can anyone here give me the best definition of the meaning of physics?? Thanks
what's biophysics doing as a subdiscipline of physics then? or soft condensed matter physics whichs studies plenty of organic materials?da_willem said:Physics: the study of the lifeless nature
Since when is an organic material alive?inha said:what's biophysics doing as a subdiscipline of physics then? or soft condensed matter physics whichs studies plenty of organic materials?
that's a bit too broad of a definition. that's...more of a definition of science in general. :tongue:Knavish said:Study and analysis of nature.
Actually, the broad definition of what science is has more in common with the definition of what physics is, than it does with chemistry and biology. For example, if we go by the question of "What is Science" as addressed by the APS statement below:Brad Barker said:that's a bit too broad of a definition. that's...more of a definition of science in general. :tongue:
another vote for the study of matter, energy, and spacetime.
Seems like the point is that Physics is the study of the interactions.answers.com said:1. (used with a sing. verb) The science of matter and energy and of interactions between the two, grouped in traditional fields such as acoustics, optics, mechanics, thermodynamics, and electromagnetism, as well as in modern extensions including atomic and nuclear physics, cryogenics, solid-state physics, particle physics, and plasma physics.
2. (used with a pl. verb) Physical properties, interactions, processes, or laws: the physics of supersonic flight.
3. (used with a sing. verb) Archaic. The study of the natural or material world and phenomena; natural philosophy.
I liked this one. Except I would replace "logic" with "mathematics." I believe the strong (edit: I think "extensive" is a better word than strong) use of math is an important separating factor between physics and many other sciences.seratend said:Another very personal/anthropomorphic view : ):
Physics is the use of logic for both the description and the prediction of the objects of our environment.
so i guess in the vein of what Mr. Rutherford was getting at, I would define physics to NOT be stamp collecting .yourdadonapogostick said:"All science is either physics or stamp collecting."
