Is bioinformatics a meme?

whats bioinformatics?
>>8461818
A meme
Is Bioinformatics the same of Biostatistics? Biostatistics sounds less of a meme.
Thoughts on this?
Lmao, i may have found the problem that broke /sci/!
Double factorials?
Are there triple factorials, too?
Try showing that [math]\left\{\dfrac{\text{vol}(B_d(r))}{\text{vol}(B_d(1))}\right\}_{d = 0}^{\infty}[/math] is monotone increasing.
At least in my old school, people were forced to study math and science for an exam at age 16.
What do you think about this? Should everyone be forced to learn math and science?
Many career paths do not involve math or science beyond a very basic level.
>>8461662
Basic math before they're old enough to think for themselves. Beyond that, no. I didn't find math interesting until years after I left institutionalized education, by which point my mind had purged itself of unused data.
>>8461662
I agree OP. While we're at it, students should also not be taught how to read and write if they don't want to. School is a waste of time, they could be working and earning money for the family instead of wasting their youth on "education".
>>8461719
Firstly, I did not mean to say that math and science were not useful. What I meant to say was that, beyond a certain level, math may not be especially useful to certain individuals.
Secondly, the math taught as this level is much less critical than being able to read/write.
for who need this
>>8461626
im not a physicist but i will save this.
>>8461626
Planning to start studying physics soon. Thanks man, that'll help me.
>>8461875
It'll help you jack shit. Memorizing trivial ass formulas won't enable you to excel at physics.
Hi, I have do a proof by induction and I just can't seem to get it. It's the induction step that's tricky.
Not sure on how to write equations here, so I have to prove that
[PIC], for every n = {6, 7, 8,...}
Basic step I guess is to show that F_n0 is true, which is F_6.
or
8 >= 7.59
Now for the induction step, where I assume that F(k) is true, but where do I start when I have to prove that it also counts for P(k+1)?
what is Fn tho
>>8461534
Oh yeah sorry, forgot to mention that. It's with fibonacci numbers
>>8461534
Its Fibonacci numbers.
>>8461521
You prove the base case where F(n) = 6 which you seem to have already done. Then you need to prove the F(n+1) case which is greater than or equal to (3/2) ^ (n)
You can break down F(n+1) to F(n) + f(n-1) because of the definition of Fibonacci numbers and you can use your assumption that the proof works for all 6,7,8,...,n to prove F(n+1)
Sorry I don't know latex hope this helps.

Good physics books for people who don't know shit about physics?
I've read these so far:
The Grand Design - Stephen Hawking
A Briefer History of Time - Stephen Hawking
The Dancing Wu Li Masters - Gary Zukav
The Elegant Universe - Brian Greene
+ a book i cant remember the title of, by some guy with a russian-sounding name, on the evolution of theories in physics in general
Anyway, these books are all written for normies who don't study physics, and I'm probably not gonna study physics ever (I study neurology), but it is a field of interest to me, and I want to learn more. Problem is, I feel that if I just keep reading popular science-books on the topic, I will never get any more in-depth knowledge than what I have already.
in general you either learn physics properly (with textbooks doing exercises) or read vague and imprecise popsci
the only exception I can think of is that you might be able to find some "history of physics" books which go into some detail about the experiments used and how people found out the precise values and equations of our universe but is still somewhat accessible to a layperson.
>>8461420
So what you're saying is, maybe start reading physics 101 coursebooks from various universities, basically?
>>8461423
you could probably try going for a more accelerated curriculum.
like you could start with a book of classical mechanics, then a book on fields (electric, gravitional, magnetic)
e.g.
McCall, M.W. Classical Mechanics
then
Lorrain and Corson Electromagnetism, Principles and Applications
then maybe
Main Vibrations and Waves in Physics
and while you're doing these you'll maybe need to refer to khan academy for the relevent mathematics, or buy a mathematical methods book for physics undergraduates.
Actually why not just do the khan academy physics course?
Without knowing anything about the values, how can this be true?
>>8461412
are you retarded?
this is stating that no matter what, if the absolute value of a-b is less than c, then b-c is less than a. bidirectional.
>>8461419
It only works if a is lesser than b. Otherwise that's what I don't understand.
>>8461412
la - bl < c iff
a - b < c AND b - a < c
Does a deep undersea cable have any impact on the power required to transport electricity (due to pressure) or is it not affected at all since it's just the flow of electrons inside the insulated material?
>>8461356
This thread is proof /diy/ is smarter than /sci/.
>>8461356
Yes the pressure effects the electrons so the whole thing goes a bit slower because the material is more dense.. You need more power to speed them up and have it working at normal conditions.
Who else went to a lower ranked university or did a subject they hated and regret it massively?
I went to my nearest university. I feel ripped off even though I paid literally nothing for it. Compared to good universities the courses were light on content and depth. In the UK all universities and subject courses arent standardised. You dont always have maths / physics / engineering students all taking the same Calc 1 (etc.) class in first year. You get "[Subject] for Engineers" and so on. So they feel free to skip shitloads of stuff (at the bad universities). They skip shitloads of stuff. I remember being in the third or fourth year of my degree, doing this really stamp collecty course and then having this crushing demoralised feeling when looking at the exam papers for Cambridges maths degree in third and fourth year. It was like staring at the secrets of the universe in comparison with my own course, which was a big fat joke.
I remember overhearing two students talking in my first year. One of them said that people who go to the library were "weird". Of course when the new shiny library opened up it was a normie haven. The old library was too small and run down yet had a lot of free space because nobody went there.
Of course your university matters a lot for how many job interviews you get. Why does /sci/ or /biz/ never mention this factor? Someone who does history of art at cambridge would find it easier becoming an investment banker / other high paying job than someone who does mathematics at a lower ranked place.
Also I hated my subject. Engineering degrees, even at good places, are, at best, just introductory chemistry / physics / mathematics introductory classes along with a shitload of stamp collecting corporate wagecuck training courses after the first year or two. Who the hell cares about that crap? Theres nothing fundamental about it. It is telling that Harvard and Oxford dont offer Engineering degrees, they offer Engineering Science degrees. They agree with me. Only fucking monkeys go to university to learn skills for jobs.
Someone with a physics or mathematics degree can do a PhD in engineering but not vice versa. That sums it up. Why would you want to limit your options with an engineering degree? For an engineering job, when all the smart engineers go in to higher paying finance jobs? top kek.
[Offensive paragraph] At universities like Cambridge and MIT, where students all enter with equally perfect grades and high intelligence, engineering has zero reputation for being difficult. Maybe it has more grunt work than other degrees. But at shit universities where people with varying levels of intelligence attend, many lower class (not judging them, but they do have less career advice than others) people go in to engineering because they see it as leading straight to a job. These are the types of people who get scared by Calc 2 and claim that it is a conspiracy to make them fail. That is why you hear so much about the "difficulty" of engineering.
Notice that I am not denigrating engineering PhDs or research, of course they have intellectual worth. But I have said that you would have to be stupid / uninformed to think that physics / maths degrees are not the best option if you plan to do an engineering PhD. On a side note, many engineering PhDs seem to be funded by corporations in what seems like a clear case of outsourcing work to PhD students at stipends at the same levels as low paying graduate jobs.There is a cucky dimension to it that cant be denied.

Nice copy pasta from last week.
Went to a State school for undergrad and got a degree for free. My masters is from a top 10 program. No one cares about my undergrad anymore.
I need to analyse vitamin d (D3, Cholecalciferol) supplements and not sure how to extract the D.
Going to be for HPLC analysis.
Grind them and do a solvent extraction
>>8461438
yeah, I've been trying to figure out what the best solvent(s) to use is.
>>8461317
I could provide you the D if you like
Is it true that helicopters from the northern hemisphere can't travel to the southern hemisphere and vice versa?
Like an American helicopter can't go to Australia, it must be shipped there and reconfigured first or the blades will spin in the opposite direction and cause the aircraft to lose control and crash.
Can anyone confirm?
Thanks in advance.
Not true at all, sorry.
The earth's rotation has an extreemly subtle effect on fluid mechanics, even less so for compressible, less dense fluids like air.

What about the Corolla effect?

nigga just read a fucking book
Is there any actual benefit to going to lectures?

>he doesn't enjoy having a competent professor present and explain abstract concepts to him.
Ask someone who met Dr. James Gates yesterday anything.
>>8461096
Did he explain his research to you or did he just tell you it's too complicated for you to ever understand?
>>8461097
I had a sit down with him after his talk. I found him sitting on the stairs an hour later talking to various other undergrad and grad students. He was a pretty cool guy to talk to. Very down to earth. I asked a bunch of different questions including what he's been doing these past couple months.

never heard of the man.
Watching this OP, is this legit or more hyped pseudoscience?
Is there any engineering field that doesn't require fucking labs?
>working with retards to do super simple thing
>writing lab report
fuck that shit.
I'm like the opposite, when it comes to problem solving, learning theory and sheer memorization, I tend to ace exams no sweat. However I cannot write for shit and I always lose/destroy things in lab or add too much of this or of that and I'm far too lazy to write long reports or focus on year long projects.
>>8460842
That's not the opposite that's exactly what op is talking about
