if i get a Physics degree, can i still do certs like in CAD and work in engineering as a technician or something? i'm just curious about my options, like if you have to be accredited to be an engineer no matter what, of if there are other positions that are technician tier.
>>
>>7848592
If you want to work as an engineer then why the fuck would you not study engineering.

ffs some people are just too stupid to reason, JUST CONNECT THE DOTS MAN, IT'S NOT THAT HARD.

>I don't want to be a physicist or do any kind of related work in pure physics
>I want to be an engineer/work in engineering

What is the best choice?

A) Get an engineering degree and become an engineer

B) Get a physics degree, then spend months getting certifications, then spend years looking for an employer so thirsty for employers that he choses me over a real engineer, and then get paid only 50% of what the real engineers are...

Hey so I've been learning Java for a little while and have now started with python. I was watching tutorials on slice and lists and I was wondering how you could print out the last letter of a string. An example would be the last letter of each word in this post, I know you need to turn it to a list. I saw further tutorials but no one really answered my question so I was wondering maybe you dont use slice for this but you use is.alpha?

Many thanks for helping !
>>
>>7848507

maybe

print(yourstring[-1])

will do the job...
>>
just watch thenewboston tutorials. he explains it for total noobs
>>
Thanks for answering but I think that will only give me the last letter of the entire string and not the last letter of each word.

yourstring = """ I want to learn programming"""
#Lets say i want the last letter of each word.
mylist = yourstring.split()
would print(yourstring[-1]) do the job?

So LIGO results get published tommorow. Probably. How many of you have your GR up to scratch enough to read the paper?

This will happen:
- half the theoreticians will see their pet theories buried alive
- the other half will try to find more evidence for being right
- string theoreticians will yet again dial another set of knobs and exclaim this fits well with their existing framework.

I confidently ignored the waves chapter in Wald back when I had my GR lecture. I probably should read up on it when exams are over.

I don't understand why our species insists on keeping our defective members alive. Before you get emotional about >muh life, consider that we chemo cancer cells because they are defective even non-malignent ones. We do the same thing with animals.

what does this mean? define your terms. it's probably infinite if you define it well, since the linear part of sin is x and the linear part of cos is 1

No no no, that's dangerous. Your body needs to be aware of your surroundings. Next thing you know, you might be tied to your bed being raped to death by 7 niggers when you could've escaped in time through the window if you heard them breaking in your house.

Try to clear your mind from all thoughts, OP. Relax your body. Solve any problems that might be haunting your sub-conscious and preventing you to sleep well.

well i wonder what your formula is.

and no, it's not n^m.

with a bit of intuition you realise that your sum of sums comes from columns from the pascal's triangle, so you get something like this with a bizarre proof :
$T_m (n)=\dbinom{m+n}{n}$
And I was asking myself, maybe I can represent this in general with some geometrical figure with cubes and shit, you know ?

What would the world look like if we allowed students to use a CAS like Maple or Mathematica whenever they wanted (i.e. during tests/quizzes) instead of teaching them to memorize algebraic transformations?

As computers become more ubiquitous, doesn't the likelihood that we'd ever be forced to go without these tools tend to zero? I can see a future where some Google Glass kind of device automatically scans and parses mathematical formula we look at and allows us to simplify/plot/solve/etc. them, so at some point things are going to get to the point where students...

>>7848022
tell me, what is the purpose of exercises? Doing them yields no tangible reward so it's not like you're getting anywhere either way. The whole point is to gain understanding and intuition.

The most important thing to learn in college is how to think logically and criticality. The solution is not the end game and memorization is not higher learning.

>>7848027
>tell me, what is the purpose of exercises?
Well in most cases it's just about applying "standard algorithmic technique #406" to a problem for the hundredth time. Allowing the use of software that makes this trivial would force teachers to ask better questions of their students.

Nothing is the total absence of "thing".

It also doesn't exist, because even space has dark energy and what have you.

Whut? Why don't you just learn it? It will take a couple weeks to a month at most.

Well, I "failed" out of Algebra 2 my freshman year of high school (got a C- so they made me switch to a lower class) and haven't gotten lower than an A- in a math class since then (currently a sophomore math major), so I'm pretty sure that was the kick in the ass I needed to get my shit together. I'm of the opinion that near anyone can learn things up to undergrad level math with hard work.

The world is no more or less "lost" than it ever was.

Not to sound like an edgy fuck, but the sad fact is that most people lack critical thinking skills and basic logic. Don't get upset about it or you'll be upset all the time. Just ignore them and keep doing as you do.
