Physicist Definition and 22 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).

    Do all great scientists possess a genius level IQ ?

    I've wanted to become a mathematical physicist for as long as I can remember. Hailing from a rather small place in India , I usually found myself smarter than the people around me .This gave me confidence that I'm going to make a great physicist one day . But now as a 12th grader who has moved...

    Physics How to go about pursuing career in theoretical physics

    I am a year 1 University Physics student and am interested in pursuing a career (if i make the cut) in theoretical physics (in particle physics/cosmology). The thing is, I know precious little about this field (but enough to get the brain juices flowing) hence the following queries: a) What is...

    Profession of Dr. Emmett "Doc" Brown

    Hi there, If you look through the trilogy of "Back to the Future" you come across many devices of Doc Brown. He's officially a physicist with theoretical knowledge, he's always claiming to conducting experiments, and he's great in building things...obviously. First question: what branch of...

    Engineering physics

    I am, currently, a senior in high school. I am interested in science and particularly in physics. So, I, naturally, want to major in physics when I go to University. But I'm not sure if I want to be a physicist when i grow up and I have also heard about how getting into academia is very hard and...

    Physics Solo Physicists

    Hello everyone, just a quick question: I have heard that it is impossible to do research in physics by yourself anymore. I heard that "The days of Einstein are gone" and that nowadays in physics, especially string and quantum relativity research, everyone publishes in groups. I feel like this is...

    How to become a physicist from an engineer?

    Hi, I am an Electrical Engineer but I want to become a Physicist and do research to develop theoretical models of elementary partials. I have applied in several universities in US for MS and PhD programs but they have rejected me, I believe because of my non physics background. Can someone...

    At what point can one be considered a physicist?

    If you have an undergraduate degree in metallurgy you can find employment as a metallurgist, similarly with chemistry. However trying to find employment as a physicist without a PhD is next to impossible. So my question is if you only have a Bachelor of Science in physics could you be considered...

    What Should I Do Next? .

    hello again, I am a physics undergrad finishing my last year, will graduate by the end of may... I am SO LOST and have no clue what I'm going to do next, mainly because in my country (Lebanon) physicists are limited to working at schools as teachers... This is something that i wouldn't enjoy...

    Anxiety and Uncertainty about Pursuing Undergrad in Physics

    So for a little background, I'm an INTJ according to the Myers-brigs test and people often tell me I have an analytical mind. I'm not a genius or anything but I do above average in physics and math. I think it's mostly because I enjoy and engage more with the material than others. I think I have...
