Here's a white blood cell (neutrophil) chasing and phagocytosing Staphylococcus aureus bacteria. Neutrophils are the most abundant white blood cell in your body and are typically the first responder against invading pathogens.

Here's ATP synthase, the enzyme that converts ADP to ATP.

How does that bacteria know he's about to be eaten? I really think the microscopic world is just fascinating, it's amazing to me how living things can be so complex and tiny all at the same time

So here I am memorizing fucking tables like an autist. How do chemfaggots justify this shitty class again?
>>7839573
You get used to it eventually. It is still bullshit that you don't get any reference material though.
>>7839573
You bloody autist! Don't memorize the tables, just memorize the patterns... Not the values, but the form of the lines.
Orgo is love, orgo is life
>>7839584
What patterns exactly?
I can see the simple shit like O-H, C-O, C-C bonds but those will only eliminate like one or two possibility.
He gives us 50 mins for an exam.
I had this faggot for orgo I and I learned the hard way that every fucking question and mechanism has to be muscle memory or else I'll run out of time.
Orgo is autism at the undergrad level and don't you try to justify this shit
Mathematics student here. How much effort do my math/sci/bros put into learning new mathematics.
I have come to believe that almost no one is born with the ability to use complex mathematical reasoning, and that anyone who wishes to be able to do so must supply the utmost effort.
Thoughts?
I don't consider it "effort" to sit down with a Springer book and a cup of coffee and read about some Grothendiecks ideas for an hour a day. It's like watching a sitcom with one eye and eventually you understand the plot anyhow. Disclaimer: I don't do proofs for a living.
How do you define "complex mathematical reasoning"? I read in a MathOverflow answer by Tao that at one point he was rolling on the floor when thinking about about some wave PDE's and I think in pictures too.
Complex mathematical reasoning can have many definitions. We could base it on average understanding of math, which gives us some idea of simple mathematical reasoning.
However, this would mean anything above calculus (in developed countries, arithmetic in undeveloped) would be complex, which to anyone in STEM is complete hogwash. So lets say mathematics that requires vigor, such as: proofing mathematics, analysis. I'm talking about things that are more than plug and chug problem solving.
>>7839623
Something like this for me as well; it depends how you define effort.
I study math because I like math. In that sense there isn't really effort involved, any more than there's effort involved in sitting down and playing a video game.
But on the other hand, of course mathematics is difficult to understand. You have to really try to understand it, and even if you're very talented you get stuck a lot.
So there's effort there, but there's also that same kind of effort at getting...

Wanna do some engineering?
Could use some input. This is a headplate for a rotating piston compressor. The two small holes are where i plan on putting bearings and a lip seal. I will press them in, but i'd like to have a way of pulling them out again if i need to replace, but i'm afraid a traditional bearing puller would fuck up the soft aluminum of the headplate.
I was thinking of putting punch out holes in the bearing race, but that would compromise my seal.
Thoughts?
>rotating piston compressor
A what now?
>i'm afraid a traditional bearing puller would fuck up the soft aluminum of the headplate.
I'm not even sure how you'd get a traditional bearing puller around those.
Gonna have to 'splain things a bit better before I can help you, OP.
>>7839571
>A what now?
a roots blower (kinda)
>I'm not even sure how you'd get a traditional bearing puller around those.
they have bearing pullers that grab from the ID of the bearing.
>>7839539
simple, press the bearings in, only sell the whole thing as an "assembly" and charge quintuple since youre the only fucker that makes it.
I believe in microevolution but macroevolution (ie a fish giving birth to a cow) is obviously false

How does one get a job working on vidya, /sci/?
>>7839473
By doing it. No seriously, just start. Write some code.

Just make loads of crappy little indie games and apps. Look at flappy bird.
Are game design degrees basically memes then?

Hey /sci/entists,
Could I make props (propellers) out of Balsa wood for a drone?
Pic related, I'm going to make them for an Eachine H8.
sure
>>7839310
Thanks
I have a PDF with around 500 pages I have to learn and partly memorize. There are pages with just photos, some definitions, examples, etc. Is there a /sci/ aproved way to learn? Should I write all the things I have to memorize on cards (which costs time) or learn directly out of the PDF?
Also because I'm a lazyfag I only have a few days left to learn that shit.
>pic not related but how the pages kind of look like
>>7839215
If you have any exams from previous years do those
>>7839230
Definitely gonna do that, thanks
Group the cards into clusters, connect the clusters. Try to find dichtonomies, or barymetric relations. Thus it becomes easier to memorize
