What is Physicist: Definition and 657 Discussions

A physicist is a scientist who specializes in the field of physics, which encompasses the interactions of matter and energy at all length and time scales in the physical universe.
Physicists generally are interested in the root or ultimate causes of phenomena, and usually frame their understanding in mathematical terms.
Physicists work across a wide range of research fields, spanning all length scales: from sub-atomic and particle physics, through biological physics, to cosmological length scales encompassing the universe as a whole.
The field generally includes two types of physicists: experimental physicists who specialize in the observation of physical phenomena and the analysis of experiments, and theoretical physicists who specialize in mathematical modeling of physical systems to rationalize, explain and predict natural phenomena.
Physicists can apply their knowledge towards solving practical problems or to developing new technologies (also known as applied physics or engineering physics).

    Was Galileo Galilei the first real physicist?

    Was Galileo Galilei the first "real" physicist? Before Galileo, I don't think there was physics in the way we think of it today. It seemed that physics was more of a philosophy to the Greeks and Romans, who just came up with theories and didn't try to prove them through experiment. In my...

    Explain molar absorptivity to a dumb physicist.

    OK chem-wizards... I'm looking at a paper which states "...the integrated absorptivity of the stretching vibrations of a water molecule is 4.89 cm micro mol^-1" (I'm transcribing a 'mu' character as micro in the above. If mu doesn't stand for micro, then let me know!) OK, so some...

    Can a physicist learn his math tools from wikipedia alone?

    Now that we have established that physicists do not need to study math proofs or do rigorous math problems, but rather just understand the math tools well enough to use them, I was wondering if a physicist can just get by in learning the math tools in a qualitative, prosaic, way as in wikipedia...

    To be a mathematician or a physicist?

    Here is my background: in tenth grade I was very average in the fields of maths and science. To tell the truth, I was far more interested in arts. But when I first discovered Newton's equations on motion, there was a big change. I was so intrigued by those that I started to read about physics...

    The Real Personality of Physicists: Breaking Down Stereotypes
