<p>I think for a science job, a PhD is necessary, especially if you want to research. A Masters would be pointless, I believe some research in industry might be fine with a Masters, but I’ve seen “PhD preferred” in the requirements. And there are a bit of PhDs going around, so let’s just change it to “PhD needed”. I heard it’s tough for undergrads in science to find jobs related to their field, but I don’t know this job market and I can’t say for sure. As far as well paying jobs in science, I heard physics is the best route; they typically command the higher pay. Specializing in physics like astrophysics or geophysics may benefit you, or may not.</p>
<p>Then again, I think R&D in anything might require a PhD.</p>
