"Tardigrades can withstand temperatures from just above absolute zero to well above the boiling point of water. They can survive pressures greater than any found in the deepest ocean trenches and have lived through the vacuum of outer space. They can survive solar radiation, gamma radiation, ionic radiation— at doses hundreds of times higher than would kill a person. They can go without food or water for nearly 10 years, drying out to the point where they are 3% or less water, only to rehydrate, forage, and reproduce."

good for dissecting...the other day I managed to stun a yellow jacket (wasp) outside my room (slapped it with my course-notes) and got it under the scope. They have an amazing sting system - you can see it until they actually want to sting something - their ass (im not an entomologist) basically snaps open like the back of a cargo aircraft and out shoots the sting.

Anyway, that's pretty low magnification so either dissections or electronics (crack the lid of an old processor, etc)

I say fracture very loosely (without knowing the technical implications) - it was a chunk which was snapped of a larger slab

[Anonymous No.6169705]

Take the number 10. Out of any 2 integers that add up to 10, such as 8 or 2, or 3 or 7, the two with the largest product are 5 and 5, giving 25. Indeed, the two are always the two integers closest to the median point between 0 and the original number.

However, there is no mathematical way to prove this.

why

[Anonymous No.6169713]

>>6169704
very polished or cut

this is a ductile fracture.
notice the "cups"

impurities/volume discontinuities form stress concentrations which allows for these recognizable patterns

>>6169713
fatigue fractures have "seashell" looking structures.

around a small crack there is a stress concentration which grows the crack every cycle
when a force is applied, the crack propagates a short distance, until it makes it to a critical distance and then the part fails

someone else is going to have to remind me about brittle fractures...

The SEM requires the sample to be conductive. If the sample is a metal, no further prep is required. For geological samples, a coating of carbon or various metals like gold, platinum or iridium are used.

If your total is <span class="math">N[/spoiler], any pair of numbers adding up to <span class="math">N[/spoiler] can be written <span class="math">x[/spoiler] and <span class="math">(N - x)[/spoiler]. Their product is <span class="math">Nx - x^2[/spoiler]. The maximum of this function can be found by setting the derivative equal to zero, <span class="math">N - 2x = 0[/spoiler], so the maximum is always at <span class="math">x/2[/spoiler]. For an odd number, <span class="math">x/2[/spoiler] is not an integer, but since a quadratic function is symmetric about the maximum, both <span class="math">x/2 + 1/2[/spoiler] and <span class="math">x/2 - 1/2[/spoiler] are integers with the largest product of this sort.

>>6170657 yea. But are you trolling with your god-shit ? https://www.youtube.com/watch?v=nh1sotIUf3I there is much more like this to discover in our universe - so why silence questions such as the of existance of it or even apparently evolution with "god" without even defining what it is that you believe in ? Why not admit that we don't know (or know to some degree concerning evolution) and call it by their proper names ?

Ok check out the fly eye. Look how the second structure mirrors the shape of the photoreceptors but in a compacted format. Is this concentrating the signal for processing?

Then that gets transferred to some type of 3d point cloud? Is this how the eye is turning 2d visualization into a 3d representation for the brain?

If you have any way to cut thin sections of rocks and look at them under a polarizing light microscope, do that because it looks absolutely spectacular.

I'll post some thin sections that I got to look at of moon rocks during a presentation last year later tonight.

[Anonymous No.6170962]

>>6170830 Great idea - gonna try that out! Though I'll probably only be able to cut sandstone or do you have any method to clear cut rocks without any special equipment ? I might buy a chinsel though but that won't be clear cut. Also got some minerals & fossils here but most of them look boring under the scope (such as wismut).

How did you get moon rock ? Would be awsome if you could post it. Got a part of the recent Chelyabinsk meteor - that'll be the most interesting stuff I'll get in front of it.
