Hey guys and girls, what sort of calculator would you recommend for university/college maths and physics? Specifically a Bachelor of Advance Science (Hons), planning to major in either maths or physics and gain a PhD. Currently I use a TI 84 Plus and it's a good one but I'm interested in other ones, like the TI Nspire CX CAS. Any other recommendations or words of wisdom?
I understand that any respectable institution will have a list of banned/approved calculators when it comes to exams. However this is more for self-study and improving my understanding of the concepts and ideas by playing around with them on a good calculator.
>inb4 you shouldn't rely on a calculator
My arithmetic and mental algebra skills won't suffer from using a calculator for hours at a time as I've already done that with my TI 84 Plus and my skills have only improved in the three years I've had the TI.
I have TI 84 plus and I can't imagine needing to upgrade.
I have seen people with fancy calculators that can do almost anything except maybe sing and dance.
All I've ever used it for is graphing and checking sine values. To be honest I don't even know a fraction of what this calculator can probably do.
I'm physics 3rd yeat btw.

Do you know the names of the fancy calculators others had? The TI 84 Plus is programmable as it has BASIC in it. I write programs for conics, matrices, solving quadratic formulas with complex solutions, etc. Writing them helps imprint the processes and formulas into my memory so I can recall them quite quickly and accurately whenever needed.
>>7724041
Sorry, can't help you with the names.
What can I say? I am an old-fashioned pen and paper man.
Whenever I need a numerical solution, I use Octave. It seems like an awful hassle to program the TI84+. I've never even looked into BASIC programming so I can't tell if you're onto something with using the calculator for that.
Can you by chance compare Octave/Matlab to using a calculator? I'm now genuinely curious as to whether it is worth the pain of getting used to the keyboard on...

Be honest with me about the hadron collider and particle accelerators and stuff.
It seems like scientists are always asking for more money for these things, but what is the purpose? If the results were useful to companies, wouldn't the companies be happy to pay? It makes me wonder if this is really useful if the government needs to pay the bill... the market should decide. Like, how does Higg's boson help me?
Also, is there any risk of funding this stuff? Like, think about the Manhattan Project. Learning about nuclear physics seemed like a good idea at...

How exactly do you expect Iran or North Korea to try and build a 30 mile particle collider without us noticing?
>>7723621
people respect knowledge, even if it has no apparent practical use today. There are groups that pool money for the purpose of developing understanding and there are people that start businesses to understand things. It's not just about money to everyone.

First year Chemistry PhD student here.
Are there any other chemistry PhD students (or PhDs) here?
What type of subdiscipline/field did you do?
I am approaching the point where I need to make a decision on this. I want to do either Physical, Analytical, or Inorganic. I definitely don't want to do Organic, Biochem, or Medical/Pharma.
I was kind of thinking of getting my PhD then working for a company instead of doing academic research as a career, so I guess I'd want Analytical for that, right? I'm interested in all 3 of the ones I mentioned, so idk.

What's the benefit of bringing a human to mars?
Literally nothing. It's a barren world that is useless to humans until we can construct orbital factories around it and send robots down to harvest its resources, which will be never.
>>7721753
Same as sending one to the moon
>>7721753
Well before someone inevitably goes into specific benefits and details, you need to ask yourself:
What is the point of doing anything? If we're not willing to set the highest goals for civilization then why set any?
Does /sci/ agree with him?
>>7717898
Well, it's by definition not science, so he's right in that regard.
As for the computer part, maybe? CS majors tend to know jack-shit about computers and instead just know how to purely code, so I guess that's right.
>>7717907
>CS majors tend to know jack-shit about computers
source?
What if it was renamed to computing science?
Would that be more accurate than computer science?
>tfw average IQ
>tfw scraping by at uni
The only thing I want to do with my life is perform medical research. I'm really trying /sci/ but I only ever scrape by on theory exams. What am I even working towards, no grad school will ever accept me to carry out research with average grades. I know something has to change but I feel like I have tried everything. How am I supposed to know if I'm not wired for this?
>mfw top-performing med student übermensch
Has anyone ever been in a similar situation or can anyone offer advice?
>>7716058
Do you what's more important than an IQ-score? Critical thinking.

Anyone else low IQ high interest here? Post feels.

Post feels relevant to having a low IQ but high interest.
So R is the set with the elements x that are not in x. But x = x, so the elements x that are not in x is nothing, which would mean R is the empty set. What's wrong with this reasoning?
what should i do if i wanted to have my thesis ready for when i finish taking all my classes, as a math undergrad? is it possible to do it without a professor? or at least only have minor details to work on

Have you ever realized that people openly block advancing technology unless they're in a war desperate to kill the enemy? Technology gets shot down my contrarians today when during Nazi Germany stuff like the EM drive, Skylon and Nuclear pulse propulsion would have gotten "fuck it why not?" government funding. Everything the Nazis funded was originally trashed by Western scientists. Rocketry, you bet your sweet ass no Western government would have poured $50 billion into Goddard's research which was what the Nazis spent on the V-2. Even the jet engine, Whittle...

what is common core math?
i cant wrap my head around it
It's a set of rules for elementary school kids, largely irrelevant since you'd typically use a fraction bar for the problem in pic related to be less confusing.
>>7725038
take big problem
break it into a bunch of little problems that can be solved in your head
boom, you now know common core.

Hi all there, I've just read an article on the wendelstein x 7 nuclear fusion reactor and it brought me back all my curiosity for atom's nucleusis, radioactive decay and fission. Now I'm looking forward to gain a better understaing of nuclear fusion and plasma. I'm actually at second year of chemical engineering and I'd like to know if you can suggest me some books about the arguments stated above, all of them. Doesn't matter if there's a title which is too difficult, I'll be glad to know and I might keep that for the future.
