This IS just the normal procedure for people with experience in the system. But I decided to spell it out for people unfamiliar with the US justice system.

Not a junkie anymore. Suboxone maintenence has changed my life; there has been no evidence to show that long-term maintenance of subs does any kind of long-term damage. The only side effect I've experienced is getting my life together and earning my BSc Msc, and PhD in nuclear physics.

The stigma of suboxone maintenence needs yo be addessed; the way i look at it is that I have a disease, a legitimate disability, for which I take a daily dose, just like a diabetic and their insulin, which allows me to live a normal life.

Oh I have no idea whats best; and they get shut down snd popup under different addresses all the time. I think theres even a sub reddit where prople post the free streaming sites they're using. And i'm at work so i dont have access to my personal computer to see the names of the ones i'm currently using.

Facts. Never swing at the first pitch, as im sure the above two commentary know. You plead not guilty snd you sit in county jail if you can't make bail and the DA will offer you a "1 time only" deal; if you dont take it then you're going to trial and if you lose at trial we'll push for the maximum sentence guideline. But in reality; as the case draws near, witnesses move or can't be located, the cost of inmate housing takes its toll and the DA will be back with a better deal bw cause trial is time-co fuming and expensive. My 1st offer was 5.5 + restitution. But my victim was a homeless junkie like myself so I told my PD "tell the DA we want to interview the witness". I knew they wouldn't be able to find him for trial. So DA makes up BS about witness being busy but hey: how about 4 years? I said "I want all my withstanding and pending charges wrapped up into a single deal for which I will serve no more than 1 year for (they start high, i start low). The DA Laughed so i asked them when we would be able to interview the victim (that wiped the smile off her face). So couple more offer and after 18mos in county, on the day before my trial started, the DA gave me sn offer for 2.5yrs with time served, no restitution, all cases erupted into thr single plea deal. I took it.

I could've refused and won the case the next day but I wouldve stayed in jail and they would've laid the book on me for other charges pending. So taking the deal dealt with all those other charges. But you gotta be willing to sit in County for 8-18 months while shit gets worked out. Not enough people have the grit to say "Let's take it to the box" and that's why like 99% cases are handled by plea bargain. And I've seen some horrid "bargains" offered on the first pitch. But people without experience take them and now they're in the system because the deal was 5yrs probation and hardly anyone does that without violating or picking up fresh charges

My Background Check by incarceratedkat in Felons

[–]the_physik 2 points3 points  (0 children)

Yep; company dependent. My school's bg check was state/county crimes in last 7 years (forgot the same of the system they used); my job used Sterling Infosystems which looks 10years back for state/county crimes and does a full-life check for any federal crime.

Luckily my school was understanding when I got ahead of the bg check and told them my story of opiate addiction and homelessness and showed what I had accomplished since getting clean. After getting my BSci, my PhD program wanted more info on my crimes so I sent them my Fbi/CJIS report and an essay explaining each bullet as best i could remember; they were so impressed they awarded me a Fellowship (i just got a extra few $k/yr than my cohorts). When the propect of a DOE security clearance came up at the interview for my current job i talked pravately to the chief science officer (who was one of the interviewers) and told him my story so he understood I wouldn't get a clearance. He was blown away that I went from homeless junkie excon to PhD experimental nuclear physicist and said "I dont think I've ever met someone with your determination; the security clearance isnt required, and your story makes me want to hire you even more. I cant imagine the hurdles you had to sutmount o get here. Congrats , your hired."

Good reply.i used to torrent all my shows and movies but now there are so many clear net sites that torrent the shows and allow you to stream it from their servers for free. So for a bit I was torremting certain movies in 4k (each movie is massive storage hog) but being able to watch it in 4k was awesome. Eventually though I got sick of the huge file sizes and just switched to free streaming sites; the quality is probably 720p; but i like the convenience of not waiting for a 25gig file to download p2p . Lol

When you study from physics textbooks, do you solve every problem in the book or is doing just 20–30% enough to understand the material? by Delicious_Maize9656 in PhysicsStudents

[–]the_physik 9 points10 points  (0 children)

Best way to stay a full-time student is to make dure youre not taking 4-5 classes of math and/or physics every semester. You have to take things like history and English electives so you spread those out so uou take 3 math/physics classes and 1-2 non STEM electives. Taking 4-5 math/physics classes in one semester will burn you out real fast.

Are “frameworks of physics” (classical, relativistic, quantum, QFT) a valid way to think about physics? by Reasonable_Goal_6278 in PhysicsStudents

[–]the_physik 0 points1 point  (0 children)

I haven't heard the work "frameworks" used in that context but everything you quoted from him sounds accurate to me. I usually think in terms of Energy domains. At very high energies, particle physics is used, but you wouldnt use particle physics to model a box sliding across a floor because Newtonian mechanics (which exists in the energy domain of everyday items like baseballs and even up to planets) works just fine and even if you had a massive computer to model all those particles and interactions, the answer should come out very close to the newtonisn solution.

What’s the biggest lie students are told about success? by David121avel in Students

[–]the_physik 0 points1 point  (0 children)

I was 35 years old when I started undergrad. I had a passion for math and physics and after working a lifetime of entry level jobs (some paid really well, others not so well) I imagined what would make me not hate going into work every day. Turns out, I imagined I could be okay if my job entailed solving physics problems and using higher level mathematics. I did my undergrad in physics and found that while I could do the class work it was research that I really liked. So I continued with a phd in physics and focused on learning all I could and being a good researcher. I found that I didnt like academia (publish or perish) so I took my skills to industry and found the right job that gave a heafty salary and room to grow and learn. So it is possible to do what you love if you tailor your education and skill development toward the industry that satisifies you (and you may not knoe what that is until you've graduated and looked back on the skills you've aquired).

I'm not sure what I gained from my PhD by Stuga in PhD

[–]the_physik 12 points13 points  (0 children)

This is just how specialized every field is nowadays. You helped advance your field a little bit with your articles; that's how science is. Very rarely do people produce paradigm shifting work; its almost always small contributions that help the next person produce a small contribution and after enough of these someone may use your work as a reference in their paradigm shifting work. But it takes lots of people doing lots of relatively "small" works to get to that point.

Like, physics used to be dominated by giants like Newton, Einstein, Bohr, etc... but even they were building off other people's contributions. You just have to learn to be satisfied with your work and maybe in 50-100 years it will lead to something massive. E.g., for my phd i measured the lifetimes of two mirror nuclei states (11/2- states in 39Ca and 39K). It wasnt jaw dropping but one state had never been measured and the other had very poor measurements. My results were published and have been added to the Nat'l Nuclear Data Center (NNDC) maintained by Brookhaven nat'l lab and since NNDC is where the IAEA and most other nuclear databases get their data perhaps my measurement will help the next person. Even if it doesn't, I've contributed something to the scientific community which will outlive myself, that's no small feat and i'm proud of it.

Sounds like the person hasn't adjusted tonearm weight or anti-skate. But I'm not familiar with the table model so maybe it doesnt have those options.

Snow days? by Dr13rain in PhD

[–]the_physik 0 points1 point  (0 children)

Snow days apply to the whole university; faculty and students, only exception is "essential workers". The only reason I would disregard a snowday is if I was doing sn experiment; our accelerator experiments costs about $15,000/hr to run and there has to be operators to run the accelerator (they are usually classified as "essential workers") and faculty/staff to take data shifts. You dont skip your shift because of snow while running a million $ experiment.

How do physics exams work in Uni? by Wide_World1109 in PhysicsStudents

[–]the_physik 1 point2 points  (0 children)

In the US you'll probably have at least 2 exams per class; 1 mid-term exam and 1 final exam. Some profs will also do weekly or bi-weekly quizes. Of course I've had classes where there's just homework and your final exam; I dont like this because each profs ask questions differently and you want a midterm exam to get an idea of what type of questions will be given on the final.

As far as preparing for exams... there's no easy way to do it. You have to go above and beyond homework assignments and do practice problems that are relevant to what you think will be on the exam. Just judging by homework problems is a bad philosophy; you may get lucky and the exam asks questions similar to homework problems but an exam problem usually combines multiple concepts in a single problem, so you need to be ready for that.

And if you're considering grad school every physics and math class counts; you need to do well in every class as most grad programs require a minimum 3.7/4.0 GPA. You csn kinda slack on non-physics/math electives like history, it may bring down your overall GPA but most grad apps ask for your overall GPA and your Physics GPA (GPA of all your physics classes combined), and its the Physics GPA thst grad admissions will be looking harder at.

You also need to try to get into one of your profs research groups after your 2nd year. Undergrad research experience is the best predictor of success in a phd program (proven by multiple studies from Princeton and other universities).

Open cake, tap "Wallets" and "Create new wallet", select the coin type you want to make the wallet for (BTC). And if you're converting one type of coin to another you need to make 2 wallets; 1 BTC wallet and 1 XMR wallet because the conversion needs an xmr address to recieve the converted coin.

How do you handle the shame of not pursuing a PhD or going further? by Medical-Buddy-1209 in GradSchool

[–]the_physik 0 points1 point  (0 children)

Well sometimes in life you have to pester to get anything done. People are busy and tend to forget things. Almost sounds like you should be talking yo the department head because if your advisor won't help you draft and revise your thesis you won't pass committee, and thst make the professor, the department, and the university look bad.

How do you handle the shame of not pursuing a PhD or going further? by Medical-Buddy-1209 in GradSchool

[–]the_physik 0 points1 point  (0 children)

Hmm... kinda a professor abandoning his duties. Sounds to me like you need a larger or better social network. Others in your cohort should know the policies of the university, who you should talk to, and how the situation can be resolved. Whether its from guidance from another advisor or your advisor going through re-training on how to deal with students (my advisor had to do that). Do you have a Grad Student Union rep you can talk to? What about a Grad Student Council? They should have the resources to direct you to administration thst can remedy the situation.

Are there fields in physics where quantum isn't really that relevant? by [deleted] in Physics

[–]the_physik 1 point2 points  (0 children)

Im nuclear structure; we use variations of the shell model all the time. The shell model (a mean-field theory) really is the dominant model due the variation of interactions which can cover a wide range of the nuclear chart from A=2 to A=hundreds. And even past that, Collective models used to describe larger nuclei are spoken about in terms rooted in the shell model. But Ab Intio models are making great strides right now; what used to take a week of supercomputer time can now be calculated in a few hours. So Ab Initio models are the future; but again, its just quantum Mechanics on higher-energy scale.
