I'm so confused can someone help me with this? The first molecule is the starting molecule and the molecule underneath is what you should get as an answer for the hydrolysis reaction. I don't really understand why it shouldn't be the second picture I posted?
this is the answer I keep getting
It's probably done in basic conditions
I can't figure out why a hydrogen is used up after hydrolysis
hi guys i need help in C coding i did the first half of the problem; however, im suffering with the second half.
I found a method, but the problem its too long and I cant write anymore code.
here is the problem:
if anybody is curious i can tell you my method...
but please somebody give me a hint on how to do this.
make a counter, write an if statement that says if a[row+1][column] == bomb
counter +=1
There's probably an easy way to check all locations around it without too many if statements.
>>8445219
does it look something like that ...

I made a minesweeper implementation in C a few years ago, perhaps this should help. https://github.com/AndrewBelt/minesweeper
Is there an actual genetic advantage for an offspring between two races?
As a general rule? no
Are there even any disadvantage? Other than a ugly child (with some races)
I feel like you missed something, but yes; genetic diversity.
Hey /sci/, undergrad baby here. I'm currently in my sophomore year doing a double major in math and cs. I was reading Hardy's "A Mathematician's Apology" yesterday, and I was wondering what you guys think of it.
Personally I think there's some truth to freshness, spontaneity, and power of youth, but like most things in life, the lack thereof doesn't wholly determine what you can and cannot do. That could just be my naivety and wishful thinking, though.
>>8444936
>That could just be my naivety and wishful thinking, though.
If you're not wired for higher math by your early 20s, it's really hard to overcome. There are some cognitive skills that don't peak until later in life, but sheer mathematical aptitude peaks for most people in their late teens.
>>8444936
>Is mathematics a game for young men?
No. Also for young women.
>>8444936
Hardy's quote is pretty stupid. It's mostly not true and as far as it is true it applies to literally everything, not just mathematics.
Look at any field of society at all. How often do the paradigm-shifting ideas come from some old codger? It's not as though a switch flips and all your mathematical talent disappears past 60, it's that generally speaking old people like things as they were and don't want to flip the world on it's head.
The (dubiously true in the first place) idea of peaking in late teens/early twenties is virtually irrelevant anymore anyway. In most fields there's so much prior knowledge required of you to do relevant work that turbo-prodigies in very fortunate circumstances are the only ones even close to ready by 20 years old.
I read somewhere that Bill Gates' roommate stated that Bill studied almost non-stop for thirty-six plus hours, then he would sleep for ten hours, woke up to eat real quick, and then he would study for another thirty-six plus hours.
How does one do this? Was Bill on crack??
Does anyone know if it's even effective to study after a certain amount of hours? Isn't there a magic number of study hours in which the brain stops retaining a fair bit of knowledge?
What does /sci/'s study habits look like?
>Isn't there a magic number of study hours in which the brain stops retaining a fair bit of knowledge?
For me that number seems to be like couple of minutes.
Usually I study for a normal period of time but whenever I have a breakthrough, a great idea, I'll get consumed by it and go at it for so long that I can no longer tell whether it's day or night. I just keep going back and forth from working to eating until I collapse.

Dont be fucking stupid no amount of studding will make your father rich,send you to Harvard and with his connections will introduce you to key business people.
If you measure the speed of a car using police radar, are you affecting its speed?
The debroglie wavelength of the car is waaaaaaaaaaaaaaaaay too big to make a measurable difference.
>>8444798
But the difference exists?
Why does it happen? Does it happen only with things that involve electromagnetic waves?
>>8444803
The waves he is talking about are material waves not em. It happens because the photon you're sending to the car exchanges momentum with it, however at these levels, given your macroscopic measurement apparatus there'd be noticeable difference.
All Doctors, Med students, Pre-med and Prospective med students welcome.
Even others who wish to drop by are welcome
Would like to discuss how other med students are doing and perhaps get insight from doctors of what shit we're getting ourselves into.
I'm gunning for Emergency Medicine, red pill me pls, thanks.
MD-PhD student here, on first year of my break. I was hoping to have a few less stressful years after the crazy amount of work I had to put to get here, so far my hopes haven't been panning out, but I'm just starting.
>>8444542
As for Emergency Medicine, I don't know what country you live in and how it is like there, but in my country it's extremely stressful. You always have things to worry about, never having real free time, always running around, pretty harsh on your personal life. A lot of people like it for the adrenaline rush, but I have no idea how you can survive doing that for a long time, there's probably a lot of burnout.
I'm in my final year of a chemistry degree and am considering going into medicine after, anyone gone from chemistry to medicine here? How was the transition?
How can a Physics degree help with getting into medical school?
Can Darwin's evolution theory be proved?
And I mean PROVED. Not "yeah we got similar genes so probably" but "YES, because of this and that"
*proven
no
>>8444495
evolution = mutation X survival of the fittest
which both are proven by science and even observable in nature by everyone.
>>8444499
Sorry, I used the wrong words.
Can the theory that humans evolved from ancient creatures such as the chimpanzee be proven? Such as the image I posted.
How do you calculate the blue area if this shape is symmetrical horizontally and vertically with a square sorrounding it and knowing the middle lines are equally long? The dotted lines are not a part of the shape. I always fail at calculating the "smaller trapezoid" (green).
x = sides of square
y = lines we know are equally long
>>8444327
x^2+xy-xh-yh
where h - height of smaller trapezoid
>>8444330
fuck, I messed up
(x^2+xy)/2-(xh+yh)
let it be so, then
>>8444332
I wasn't quite sure whether I'm allowed to introduce h as height, without calculating it from the given variables. But I guess there's no other way.(?) Just wanted to dubble check.
how can we save the ecosystems of our planet, reduce overpopulation, and prevent habitat destruction and extiction with our current technology and systems of government?
>>8444323
>save the ecosystems etc etc
why?
How much of your income are you willing to give up to save some stupid ducks?
>reduce overpopulation
define "overpopulation"
Do you have some magic optimization algorithm that gives you the ideal number of people on earth? Based on what?
>>8444323
Hitler 2.0 but for africans, middle easterners chinese, the uneducated, and possibly indians.
>>8444343
its not just stupid ducks though, we as a race are killing our planet. those stupid ducks can easily be swapped out for almost any living creature larger than an ant and the meaning stays the same. all life across the planet, including our own, is affected by pollution, greenhouse gases, and industry to the point where we've fucked our planet up immensly in just over 100 years. Saving populations and entire species is more than just letting creatures go extinct, it destroys entire ecosystems, some that directly effect us. so yeah Im okay with putting some of my income into saving the planet.
As for overpopulation I dont even think I need a model to show that to you, china alone has over a billion people. the sheer amount of waste and pollution we humans create from a highly concentrated population like that is disgusting to say the least.
Can you guys hook me up with a free ebook on basic Linguistics? Our class was tasked to do a Phonological/Lexical/Syntactical/Semantic Comparison of the English Language to other European Language/s and I don't even know how to start. Yeah I'm pretty much of an ass but could you guys help me??
>>8444148
>a free ebook on basic Linguistics
go to bookzz.org and download whatever looks good to you
C'mon guys I know there are some of you who knows Linguistics...
>>8444166
Thanks!
do you know Linguistics? got some tips??
Answer
It preserved Aristotle's writings and continued to develop scientific innovations while science was dormant in Europe during the Dark Ages.

Historically, development in science and maths occurred not because of Islam, but in spite of it; as the great majority of so called "Muslim scientists" were not Muslim Arabs, but Persians, Greeks and Spanish.

What a psychologically weird post.
Scientists are liberal. I'm not liberal. Scientists are supposed to be smart. So they should agree with me because I must be smart. I'll kill you if you don't agree with me, you scientists. Now they will agree with me and I will be smart.
>>8444223
>Scientists are liberal.
I didn't see a single scientist asociated with BLM, pro-migration groups, blindly supporting minorities, pro-muslim, LGBT activist or any other destructive libtard agenda.
Liberals are notoriously anti-science. Being a centrist is as far as scientists get close to liberalism.
Anyone have an intuitive definition when two units are multiplied to create a combined unit?
It's pretty easy to find an intuitive sense for division, such as velocity. For every interval of time, there is a change in position. How about something like Force? for every second squared there is a change in "Kg*m",wtf does the latter mean?
for every acceleration of a kg there's a force
most of my intuition comes from recognizing the two chains
1) position --> speed --> acceleration
2) force --> work/energy --> power
>>8443865
ignoring the seconds, what does kg × meters explicitly mean?
Or how about work, Newton times displacement, what is the intuiviatw sense behind that? For division it's "per".
>>8443870
Yeah I always thought of things in that order. But work is the integral of force and displacement, and power is the slope of work with respect to time. And I'm having trouble finding intuitive sense for an integral, or multiplication between two units, so I'm kind of stumped on force/work.
