Trends come and go. I'm sure 5-8 years from now the implant craze will be past. Ten years ago it was all about how AI will replace humanity and usher in a world totally foreign to humans in which humans are obsolete. Now it's harder to find fiction like that.
I found an article written by Poincaré in sometime before 1912, literally also called The Value of Science. The first paragraph mirrors Feynman, but then it diverges considerably. He describes how Truth is the only thing that is beautiful, and so the arduous search for it is worthwhile. Also...
I just read Feynman's The Value of Science and really appreciated his perspective. We generally value art, literature, and poetry but if you want to do science for the sake of science people take offense. It takes years to build a foundation before you can appreciate it, so the general public...
This is simply a matter of history, not of rigid definition. It's nebulous and you're going to have to be comfortable with that. Fluid mechanics developed into its own domain, with its own tradition, so if you take a course or read a book on "condensed matter" it's not going to cover it. Same...
A lot of software companies hire for specific skills, so having a bachelor's in physics plus any sort of concrete demonstration in skill should get you a job. Class projects or mini research projects or something you did in your own time - highlight that in your resume and be well prepared to...
I think your question has been mostly addressed. A lot of fridges run on a simple control scheme, where the compressor is either on or off. It's not regulated on how much it's cooling, but gets colder the more it runs. So once it warms up above some threshold it runs until it reaches the set...
Variance and standard deviation and other measures of error I understand. This formula doesn't behave well for data sets centered around zero and also has other problems, like scaling differently as N increases than the standard deviation or standard error. Does anyone recognize this and can...
If I understand what you are asking, the answer is yes. Strain will affect the energy of an individual atom in the lattice. There is no simple formula I know of, it has to be solved with DFT. The typical method is to model the lattice with matched boundary conditions, but your unit cell is...
I guess that's the huge difference between fields in physics. Working in nano and photonics, I publish in a lot of materials journals as well as physics, so single-blind can be expected. No one can keep track of several thousand researchers all doing related stuff.
No journal I've ever...
I am looking for a textbook or handbook on optical system design. I would prefer one that actually derives equations rather than just slapping down rules of thumb, although I would take the latter. My problem is that I've done a ton of bench top optic setups, but my skills are kind of capped at...
I just looked up my CEO's salary. It's $600k base plus $3.2M in stock. I did not know he made that much. Holy cow. His career was PhD Mechanical Engineering, 6 years as an engineer, then changed to engineering manager. Then two decades of slowly climbing to higher management positions.
I graduated with a PhD in "physics" and went straight to a six figure job doing actual experimental work. I'm currently job hunting again and am getting familiar with what's available in my area so I'll give my perspective.
1. First tip - start going through job boards now (indeed, linkedin)...
This had made me realize there are other fundamental things I am not understanding. Maybe the understanding of a fs pulse is related to the understanding of a photon.
Let's say a photon is a wave packet. So the single "photon" is made up of plane waves of a wide band of wavelengths. But when we...
