No, it's just the voltage source if it's the other side of the resistor. You're measuring the total voltage dropped over the entire circuit...

Yeah, that's what I meant.

>>6383024

Well, we can't see shit. Lower the frequency.

Right now I think you measuring from black line to black line (i.e. both the resistor and the cap), which is just going to give you the original signal...

Yeah, bunch of cocksuckers who just want cheap labor, even though the engineers/scientists are what make the companies successful.

I think it's trying to get you to measure the voltage across the "output" i.e. the voltage across the resistor.

>> No.6383004 [View]

Not sure for circuit sandbox, but for something like ltspice you'd set your voltage source equal to some variable, then set up a voltage or frequency sweep, and then once you're in there, you can just click the wire at the two places indicated.

It is true, it is true.

Also, it's very weird at the top, because PhD degrees can change from hot to utterly worthless by the time you finish your PhD. Your ability to think critically and solve problems will be great afterward, but nobody gives a fuck because most companies can find someone with hands-on in exactly what they're looking for (and if not here, then from another country), and that's what matters most if they're trying to get something out quickly (more engineering type jobs).

R&D. Semiconductor growth and characterization.

Academia is a shitshow right now, at least in the sciences. The number of graduates coming out of the top five schools in any given area are enough are enough to fulfill available faculty positions (although group reputation > school reputation).

>>6380292

I think groups are going to get larger and larger, like the system in Japan, where one professor has a very large group, with associates professors under him/her, then postdocs, then students. It's already happening to some extent, there are a lot of very large research groups that just keep getting bigger, with postdocs acting as advisors.

I wouldn't be surprised if they changed tenure, at least in the sciences. Traditionally, it was supposed to give freedom to speak your mind, research what you want without censorship. The way it is now, tenure really doesn't get you a whole lot of perks with respect to your research, because most of what you are able to accomplish is tied to grant funding. I have mixed feelings on this; grants tend to homogenize research, make you focus on short term projects that will definitely produce results instead of trying high risk/higher reward type research.

1. New method (or equipment) used for synthesis/growth of material X that is cheaper/more scalable/provides better quality of material than existing method.
2. New method of making an electronic device.

The patents are written in a way to make what you have done overly broad in scope, so it covers anything else that someone could possibly do with your invention.

Background, very brief, broad.

Summary of invention is going to describe you invention in a way that much covers anything else that someone could do using your work, like "device may be integrated with other devices and processing techniques."

Description is the meat, and pretty much covers any other things that may be done in parallel, "the device may also be patterned using lithographic techniques." "the device may also have/contain/use this, this, this." All this so people can't say "well technically it's not the same because we do [this additional step]" when it would be pretty obvious to someone in the field that it's a ripoff.

Lots of figures.

Usually you're going to have someone in your company to help you with patent stuff.

Maybe consider the sum of the mods of the individual terms?

x^n = A mod p, where A is nonzero, since x is coprime to p.

No, I love the field. I just regret my choice of academic advisor. He doesn't have much knowledge outside his immediate area of expertise (which isn't bad per se, most PhDs do have a narrow range of expertise), but coupled with arrogance of being an advisor and making demands that don't make sense, it's just a bad mix.

I could speak more on why I think academia is fucked up in the US, but it's a long story.

As of now, I have like 10 peer-reviewed papers, plus like 10 conference proceedings that list me as an author? 3 of the peer-reviewed papers are first author.

24.

Something nobody cared about nor will ever care about in the field of materials science.

First author, only author besides advisor.

Was it good? That's a tough question. I was given a project as a graduate student because my advisor had funding for it, and I did what was asked of me, developed the methods, etc. and did a good job with the project, but I hated that research, and an extension of it became my dissertation, which is also something nobody cared about then and will ever care about, which made me pretty miserable during graduate school. Especially coupled with my boss' arrogance about the project at first (which motivated me), followed by dismissal of it once he realized it wasn't "in vogue" anymore, nor was it useful (which I also realized, and I felt kind of betrayed, because I was very naive when I entered graduate school, and thought that at the school I was at, which was top-10 in its discipline, would offer nothing but cutting-edge research).

I was fed up with academia, and thought really long and hard about whether I wanted to do a postdoc (which would give me the freedom I lacked in graduate school), and then become an associate professor, where I realize my "style" isn't necessarily the best fit for academia. I like short "can we do this?" type projects that will translate pretty quickly into a yes/no answer, and may not necessarily be "sexy," i.e. new technique, or something that looks pretty on the cover of Advanced Materials or AFM, because I think that the "can we do this" types of projects have the best chance of actually being useful in the real world.

So it was go along with the system in the hopes that I could be one of the "good" advisors, or just go into industry. I'd maybe like to return to academia someday, as I do really love teaching. Maybe at a small liberal arts college, although they typically don't have materials science, but perhaps in another department?

I'm more proud of my patents than my first paper.

Classes that require you to learn nomenclature are shit; nobody cares, it's obsolete. Tell your prof to go fuck himself, because he's being lazy by wasting your time with this shit.

Isopropyl will (always?) be 1-methylethyl in IUPAC..

I guess you would start with the ring.

Where does numbering start: well, it's either near the isopropyl (excuse me, 1-methylethyl) or the methyl.

I think you go alphabetically here? So methyl > 1-methylethyl.

Then you just have to figure out how to name the ring. Apparently, it counts as 8 "carbons" but the 2,3 are oxygen. So, yeah, no clue how to name that fucker, and
I wouldn't know where to start if you didn't give me the name.

My god, just call it fucking ascaridole, I don't know how to do this shit anymore.

Sometimes. A lot of them would be considered "inorganic" like P450 (iron porphyrin), nitrogenase, oxygenases, because a metal center is the site of catalysis.

Yup, PP.

Also, paste as enhanced metafile (instead of normal paste) for graphs from software like origin, or it will run like shit.
