Has anyone else ever done this?
I recently found some really useful lecture notes online that I wanted to have a physical copy of, but they were too long to print out. So I had a book made and it was quite cheap.

On our university campus there's a shop that does all sorts of printing and binding. I've had them print tons of lecture notes for me.
I find it easier to read lecture notes than a proper textbook because lecture notes are written more formally (instead of flowery English prose) and they seem to explain intuition better.

How is this blogshit thread worthy?
>>7770256
How is this not a textbook? It's not condensed much at all.
The whole point of notes is to leave out all the filler in textbooks and get straight to the point.
How do you study, /sci/? I,
1.Write all of the definitions in a chapter.
2.Write a checklist of what I'm going to do that study session
3.Skim the chapter quickly and then try to condense it into three or four pages.
4.Finally, once I think I know the material well enough, I do the questions in the book and some exam questions.
Is there anything you do that you think is better than that?
How do you study?

HELP
I CAN'T FOCUS ANYMORE
I rewrite and rewrite and rewrite
>>7770465
How do you organise that? Do you throw out the old stuff and begin a new page?
Why do fractions exist at all.. It seems pointless and confusing.
It's much easier for me to think of 1/12 as just 0.1 in a 12 digit notation.
multiply 1/12 by 4/12.. ok 0.1 x 0.4 in 12 digit notation.
no need for learning stupid tricks like multiplying by the reciprocal etc that just avoid explaining the actual concept.
Am I missing something / am I autistic?
it can even be scaled up to more complex problems as long as you remember that you're in x notation and convert back to decimal notation at the end. Am I wrong?

Please do not post on this board again
>>7770149
So you are implying that is also easier for you to think of 0.5 as 0.1 in 5 digit notation?
So If you have say,
0.57371 that is 0.1 is 57371 digit notation?
I think you are autistic? Are you implying that every fraction we do should instead with replaced 0.1 and a explanation for what the base is?
That is fucking autistic. Working in a single base is better and easier to learn and to work with.

Stop. Everyone says this here and means it.
I'm just proving how pathetic it is.

It's a mental illness.
There's that familiar feeling again. When the present state of research can't satisfactorily answer the most base of questions, and every scrap of literature you read contradicts another. Then you get the reviews that read like opinion pieces.
I just read a whole review, complete with a few hundred citations, that was essentially trying to say the only pharmacologically relevant components of cacao seeds were flavan-3-ols, methylxanthines (mainly theobromine), magnesium, and some other antioxidants. The rest of it was a snotty half minded display of trying to "debunk the myths". Clearly this fuckhead has never been high on chocolate, subjectively it is absolutely nothing like other caffeine, theophylline, and theobromine containing sources. Nor does it behave the same with longterm administration. I would know, the majority of the good parts of it disappear and it leaves a bit dull.
No. I want to know how it actually works. I want to know what it actually is relative to the human machine. This is ridiculous that it seems it still isn't known to what extent isoquinolines can be absorbed through the intestines. And through all their bitching about "lul anandamide myths, weed heads too xd" they neglect to mention the presence of endocannabinoid reuptake inhibitors. The nature of which, isn't known either.
[Character limit]
This is one of many things that is beginning to really piss me off. I can't stand disjointed garbage that doesn't fit together, and I hate even worse stupid shit making its way into the available body of literature. It's one thing to try to substantially dispel myths and try to make it clear a good direction for further endeavor it's another thing to say idiotic shit that doesn't agree with experiment or empirical observation. Maybe this moron should have spent some time eating enough chocolate to get high on (not as much as you might think), rather than writing his bullshit.
I'm going to have to fix this myself. I'll spend years at it. I'm just so fucking tired of this, and it's one area I'd like to set the baseline for how the goddamn thing really works. A series of papers that really defines a solid foundation and framework to reference later as knowledge expands and shifts. There have been rulers that supposedly subsisted on this. We've eaten it for thousands of years, and still barely know how it works on even a high level. This is a pathetic mess.

I've never experienced this "chocolate high"
>>7770026
Go get either some high quality dark(er) chocolate. Make sure it contains both the butter (fats), and the solids. Sometimes this will be listed as "chocolate liquor", which just means a roughly 50/50 proportion of cocoa butter and solids. Make sure it's not processed with anything (dutch process, roasting, alkali, etc. This is done to reduce pH and control bitterness).
You can either do this in the form of cacao nibs, chocolate chips, or chocolate bars. Chocolate chips is probably the most viable, but also involves a spike in blood sugar which makes results less clear. Nibs don't have this problem.
Eat a lot of it. Take it slowly, and you'll know what it is, as it begins to be. Some aspects are very, very similar to ethanol. Almost identical. Which makes me pretty apt to assume that salsolinol is in fact absorbed in some capacity. You're definitely not pulling in a lot of acetaldehyde.
Man, this is chocolate we're talking about, for fuck's sake. It's not hard to do this experiment yourself.
Did you follow your dream in your choice of study?
If not, What did? Money?
How is it going now?

>Did you follow your dream in your choice of study?
Yes, Pure Mathematics.
>How is it going now?
Just in freshman year and I already got a paid internship working in banking software. I start monday.
Man, being a mathematician is like living life in easy mode. Literally everyone wants to hire you. You got software on one side, statistics on the other, finance on another, research everywhere and rich people want you to tutor their rich kids.
10/10 man.

I picked mathematics because it's very little work
Couple of homework problems each week is at most all they grade, the rest is just exams
No papers, no projects, no groupwork.
All you have to do is study an hour or so a day (at most) to keep up and that's not too hard because I enjoy mathematics anyway.
Life as a math major is easy modo
Well I'm officially stuck. I'm reading through Birkhoff's and Beatley's Basic Geometry on my own and I can't solve this one.
"Prove that in triangle ABC, bh = ck, where h and k are the altitudes on sides b and c respectively. Suggestion: Look for similar triangles."
Altitude is defined as "the line from a vertex of a triangle perpendicular to the opposite side".
Oh, and we know "perpendicular" is 90 degrees.
Onto the axioms we have (a bit abridged, but odds are not all of them are needed):
1. The ability to measure lengths of lines
2. There is only one straight lines through any two points
3. The ability to measure angles
4. All straight angles have the same measure (180 degrees)
5. Case 1 of similarity: Two triangles are similar if an angle of one equals and angle of the other are the sides including these angles are proportional. E.g. both are 3 times as large as their corresponding sides.
Theorems I believe important to solving this are that we know that two triangles are similar also if they have two angles equal to each other, and we also know about vertical angles, aka opposite angles are equal to each other.
>>7769845
The area of the triangle is 1/2ck=1/2bh
QED
>>7769850
We haven't defined area yet, bub. Neither have we anything that shows that if two triangles have the same area they are similar.

Is buteyko a legit method for everyday breathing?It seems like it does wonders but i never seen it discussed.It would be great if some anon can take a few minutes of his time to read the info on this site.

I'm no doctor but that sounds really fishy to me
I mean they claim that with their technique you

In the animal world, females choose the most attractive males for mating (because eggs are less common than sperms), so how come it is the opposite in the human world?
Pic somewhat related
Human Females have one night stands with the most attractive males then settle down with less attractive males because they are good providers
It depends on the animal species and some animals don't even have genders to be able to follow that. Stop trying to apply what you learnt of birds to everything
because men show off to women with money and utility, showing their social status.
having a peacock tail wouldn't be very advantageous to a female.
Why haven't we used genetic engineering to evolve humanity into immortal super-powered god-beings yet?
>>7769464
Man just shh, people are trying hard to do that.. like really hard. Just participate how you can and stop complaining.
>to evolve humanity
evolution is *FROM* a prior form, not *TO* a posterior form
Lrn2evolution fgt pls

I don't care about semantics I just want humans to be replaced by something better, also I'll use words however the fuck I please you pedantic little pre-Madonna.
I've recently become interested in planetary accretion.
Does anyone know of any good papers I could take a look at? I'm an undergraduate in physics/geology if that helps.

yes. the point is to see how bizarre the actual paths of the planets would be if earth was the center of the orbit.
So I went hiking at Blanco County, Texas, and found this rock nearby a stream.
What kind of rock is it? And what are those little holes??
I tried the web and nothing! So maybe someone here is into Geology.
I'll post other angles.
Its just water erosion. Seen it plenty on the appalachian trail. It may also be from glaciers, but since its in Texas, its probably from a delta from the past.
This is the back...
Is biophysics a meme field?
Yes anon, it's a meme field. Those thousands of papers written, peer-reviewed and published in prestigious publications? All memes.

It's Biology+Physics therefore, Biophysics
I am being 100 percent serious and my friends don't believe me, I believe that everything in the world is a 50/50 chance like there is a 50/50 chance i meet snoop dog or i dont tomorrow or It rains or doesnt rain tomorrow. someone try to prove me wrong with facts and evidence right now.

Looks like my luck has run out. There's a 50/50 chance that you'll shitpost. Thanks a lot faggot
