Did you read section 8 and 9 in the attached notes? What parts aren't clear?

There's probably not enough time left for Northeastern before the priority deadline, but for schools that have a later deadline you should definitely reach out. For example, BU is Dec. 15, you probably have time to reach out and inquire about their program without making it seem like an...

Yeah. I just mean adding in that you had no opportunities to do biophysics research as an undergrad isn't going to really help you at all. Wording it as FSUs failure also seems a bit disingenuous. I would drop it completely and think about how the research experience you had as an undergrad led...

I think if you're applying to graduate school they have a pretty good indication that you have a solid background in the core classes. The last sentence here should probably rewritten and made the first. This seems good. Also good. This has some good information, but it could use a...

The girl is probably real, albeit heavily filtered. The singing/music is just a sound track placed on top of the video, it's almost certainty not her voice. Lol, you have parents who do this to make money off their children. The USA will fear monger whom ever to raise more money for defense...

This is legitimate. PBS source They do this all the time. They're even talking about putting missiles in Cuba again. Around and around we go.

This doesn't seem like an insurmountable problem. Large content creators and celebrities' should just take a note from the cryptographic world and start issuing certificates that a video is legitimate and video hosting platforms like YouTube and Facebook (and end users to some extent) should be...

Looking for second edition Landau and Lifshitz hardcovers to complete set. Would like to pay 30-50 dollars per volume depending on condition. Dust covers aren't required.

Chinese factories scamming their customers? A tale as old as time. Lawn darts are also back, not they're just made of plastic and have blunt ends.

The two most annoying things in trying to maintain other peoples C++ code was people not realizing how short circuiting worked so you ended up with syntax like function(x) && function(y) which is obviously bad when you're expecting function(y) to always run. The other is related in that you'd...

If you keep reading through the link you've posted you'll see that you're defining ##A^{\dagger}## wrong. ##A^{\dagger} = KL^{\dagger}## . You can reach this same conclusion using the definitions as above. Aka K is antiunitary.

Yes, it's going to seem rather silly I think when you see it: Write the general form of ##(<\phi|\hat{A})|\psi> = a\psi_1 + b\psi_2## Now use your given definition to figure out a and b, ##(a\psi_1 + b\psi_2) = [<\phi|(\hat{A}|\psi>)]^* = i\phi_1\psi_2-i\phi_2\psi_1## So ## b = i\phi_1## and...

It's a distribution, or continuous linear functional. You're quoting the insight but didn't actually read it. The insight itself would shed light on why what you're saying is misguided and the wrong way to think about things. Also I don't know what a degenerate function is, but it is a...

Sure: https://www.niu.edu/clas/physics/academics/graduate/phd.shtml If you enter with a masters degree or a pgre score > 50% here you're waived from needing to pass the qualifying exam. At many schools in which you can earn a terminal masters in the US in physics all have a tagline of "skip the...

Having a masters exempts you from quals in the US. You're assumed to have passed already. Unless the department has some PhD specific qualifying exam.
