Hey /sci/,
So as part of a lab I pictured a piece of unidirectional CFRP in a scanning electron microscope. Only thing is I got a strange pattern of tensile and compressive failure (picture included).
What global loading could lead to this failure pattern? Any help is greatly appreciated.

I think you've misunderstood where you are. Please restate your question in the form of a shitpost.

I'm just asking in an attempt to understand what's going on. I couldn't find anything similar anywhere online so was just hoping that somebody on here had seen something similar.

>"The only difference between mathematicians and coms sci majors is that comp sci major don't know calculus, are you a comp sci major ?" A former teacher at my faculty when asked by a student why we had to do "hard" calculus problems.
(Since my faculty has both a computer science department and a math department ,they used to be joined a while ago, like 10 years ago, and even both majors had the same courses for almost 2 years)

Why are rockets shaped like penises? Why not squares, rectangles or circles? Are penis shapes really more aerodynamically efficient?
Serious question.

Nature has had 3.5 million years to find the best aerodynamical object for stabbing shit, so yea, it is the best shape

>Are penis shapes really more aerodynamically efficient?
No, that's just a meme.
It was really all the fucking pig men at NASA that decided that that's the shape they will be going for. Because when you want to pierce the heavens then you got to have a giant dick, don't you.
They got that design from some NAZI scientists btw.! They wanted to tribute their neo pagan gods.
Fucking disgusting if you ask me
>>
>>7911747
I think it has to with surface to content ratio. If I make it a cube shape you have more metal to carry per fuel which makes it inefficient.

Is there a recommended chemical to specifically destroy DNA?
Let's say I have an object I want to throw into the trash. But I touched said object and even ejaculated into it several times. I do not wish to leave genetic traces. With what chemical can I treat this object in order to make sure I cannot be identified anymore?
To prevent stupid questions: It's about my cum jug in which I collected my cum over months. I washed it out but I'm sure that's not enough.

Why do people consider physics to be such a great discipline when it's basically just pure math for people who cant do pure math? Is it because most of /sci/ is living this inadequacy and don't want to admit it to themselves?

What the hell am I looking at?
Why are these the videos I see before I actually find something remotely related to CERN? What kind of person floods the Internet with this stuff and who is promoting this trash?

>Why are these the videos I see before I actually find something remotely related to CERN?
Because /popsci/ people are more interested in the idea and potential of CERN rather than their accomplishments.
>What kind of person floods the Internet with this stuff and who is promoting this trash?
People who recognize that former statement to be true and want to make money off of it.
Seriously OP, think for a second before you shitpost.
>>
>>7911050
Popsci people are more interested in loosely misinterpreting actual science rather than putting out conspiracy videos though. Making anti-science videos would be obviously counterproductive even to the popsci community.
