How do you cope with foreign lecturers with thick accents?

Had the same problem and decided to just read a fucking 1000 page book instead of trying to decipher her retarded accent. It was much, much easier.

Some PhDs should be shot, working your ass off to write a shitty dissertation and pass some exams isn't something that entitles you to have a shitty, indecipherable accent. It doesn't entitle you to be a fucking unlikeable retard who doesn't know how to socialize and speak. If people like Turing, Einstein, Feynman, Grothendieck, Euler, Euclid, Archimedes, etc shared their knowledge and were mostly likeable, funny, adapted persons then a random PhD bitch who teaches has no excuse. Didn't Euler go to fucking Russia, had 2 different wives, 15 children and was respected by royal families? That's surely a sign that he knew how to adapt, socialize and communicate. Surely it would've been impossible to become liked and respected by inbred, royal fucks if he had a thick, retard accent.

There are accent courses available for free on the internet. Fucking adapt and learn to communicate you dumb foreigner. God fucking damn it.

ITT things that caused you to lose faith in the common man.

I fucking hate Ben Stein ever since my grandma sent me to a christian conversion thing for atheists and undecided. I tried to go in with an open mind to listen to their reasoning, but I just lost it when I saw this film with Ben Stein where it was just nothing but an endless stream of fallacious arguments one after another. It was actually amazing how quickly he could move from one flawed line of reasoning to another.

What pissed me off the most was that the logical reasons he gave were wrong in such subtle ways that I'm sure they would be very convincing to stupid people or people who have no education in regards to logic.

To clarify, by "lost it" I mean I lost all respect for the program and decided not to go back for the next meeting.

https://academia.stackexchange.com/questions/87737/depressing-tutoring

Oh, mein Gott:

>Tutor (Master's student) who recently transferred to an unnamed European university bemoans the standard of the 1st year maths undergrads there, saying they struggle to solve simple matrix equations
>An American CC prof replies:

"most students entering U.S. community colleges do not have 8th grade algebra skills, nor even 6th grade arithmetic skills (e.g., fractions, proportions, negatives, estimations, times tables).

[...]

"I've had a good chunk of a college math lecturer career at this point and I've never taught anything as high level as matrices.

[...]

"Many also clearly have learning disabilities"

Thoughts?

No thoughts

No words

Maybe because not everyone is good at math and if they were they would most likely not go to a tutor for help.

most students entering community colleges aren't going into a STEM field so it's ok

There's a ton of resources on how to do it.

A basic way I did it was:
1. Go somewhere you can't easily get distracted
2. Don't bring shit unless you 100% need it to study/do whatever you need to do. So, leave behind your phone, and laptop if you can.
3. Set a hard time to do it. For some reason, It's a lot easier to do it when you say "I'm going to study from noon to 2 p.m." than "I'm going to study for 2 hours today"
4. Take little breaks while you're study. This varies from person to person. Some do 5 minutes per hour. Some do 5 per half hour. Experiment, and see what works for you.

Another thing is a lot of people get really distracted when they start studying, and get discouraged by it. I think that's more of a symptom of the age we live in now. It doesn't mean you're retarded, or hopeless. It means you spend too much time on 4chan/reddit/your phone constantly searching for things to grab your attention. If you can handle going on those sites in small doses, then whatever. If not, cut 'em out for a while. It can't hurt to see what'll happen, and you're not gonna miss anything. It takes a while to correct itself.

Is there any scientific reason not to be a vegan?

B12 and Omega 3 seem like valid reasons, but the obesity and hypertension rates of non-vegans are so high that I don't think it matters anymore.

I have been vegan for like 10 days. Massive amounts of gas.

Hi /sci/

Do you guys know if vortexting or sonicating a solution can break antigen-antibody bonds?

I am basically capturing an antigen using beads that are coated with antibody. However, when I ran my experiment today, I did not detect any antigen on them. I spiked in antigen so I know it should have been there initially. Do you think vortexting/sonicating the solution screwed up the bonds? I can't find any info online.

Thanks in advance!

>>8817874
Could the antibodies have come off the beads during sonication?
>>
>>8817885
maybe, that's what I was wondering. can that happen? i thought sonication works on the micron scale and would not impact the nanoscale molecules
>>
>>8817928
I honestly have no idea but I don't think it would be an issue. I'd check other variables first, e.g. incubation time. What did you use/how did you check whether there was binding?

Several threads here state that only if you are naturally good with mathematics you can consider yourself intelligent.

I remember my readings about Beethoven. In some biography or article, I read that he was terribly bad at basic arithmetic.

Search in Google, find info about it:

http://www.telegraph.co.uk/music/classical-music/seven-surprising-things-you-never-knew-about-beethoven/

https://books.google.com.br/books?id=kvauCgAAQBAJ&pg=PT20&dq=beethoven+arithmetic&hl=pt-BR&sa=X&ved=0ahUKEwiVrJiduprTAhVCl5AKHRSrC344ChDoAQgZMAA#v=onepage&q=beethoven%20arithmetic&f=false

https://books.google.com.br/books?id=ZtfuAAAAMAAJ&q=beethoven+bad+arithmetic&dq=beethoven+bad+arithmetic&hl=pt-BR&sa=X&ved=0ahUKEwi1tbrJuprTAhUGi5AKHTqoDOo4ChDoAQg2MAQ

So why do people here keep insisting that one needs to be naturally capable at math to be intelligent?
