Physicist Definition and 662 Threads

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).

    Physics Questions for an aspiring physicist

    I'm currently 16, pretty young to be thinking about my future like this I know, but I really like science. Not so much experimental but that might change seeing as how the only ones I do right now are really really basic and don't interest me at all. But that's not to say I don't like science...

    Is it possible to become a physicist if you had bad grades.

    Im in high school right now and my physics grades are around Bs. The reason why is that I usually procrastinate and don't do homework plus i sometimes freeze up during tests but i usually understand the concepts and the math is usually easy or straight forward for me.
