If you're knapping it, it needs to be a ceramic. Ceramics can be incredibly hard, but they're brittle. What this means is that their ultimate (breaking) strength is equal to their yield strength (the point at which they begin to deform). As a result, a collision with something ductile (iron) may bend the ductile material, but shatter the ceramic.

Your fantasy material doesn't exist. Obsidian is probably the closest real life thing, but it's going to shatter when used to strike anything.

>>8917814
I am very sure it doesn't exist.
That's more what I'm asking, what combination of qualities is most desirable?

Like, to raise its ultimate strength high enough to collide Iron without shattering what trade off would be made? Weight, difficulty in shaping, size of piece required, etc.
Trying to get a good idea for the balance of factors required.

>>8917819
A composite would likely be the best solution. Something like your picture. You'd want the main blade of the weapon to be a bit flexible, but the cutting edge can be incredibly hard. Maybe a hard glass embedded into a metal or something similar. Perhaps your blacksmiths have developed a method for a replaceable edge due to their lack of access to high quality metals?

If it can be knapped, I can't think of a way to make it withstand impact on it's own. If it could survive a collision, it probably can't be knapped.

for fuck sake

Damn son

What a stupid question, there are no two things that share a closer relation. The question is whether hard work is deterministic and resultant from biology or whether they is an individual and psychological role.

Im still saging your troll thread.

>no 2 things that share a closer relation
Aren't you forgetting IQ and success?

>>8916338
forgetting biological components such as IQ. Hard work does not equal success Smart work equals success. OFC you have to output some work in both cases.

Was reading this blog about failures who wished they had gotten PhDs, and tons of encouragement came from brainlets who had completely failed during their undergraduate in math/physics. They ended up getting engineering related PhDs, kek.

What's your definition of actual math OP.

>>8912097
Category theory penetrates pretty much all Algebra, Algebraic Topology, and Algebraic Geometry. So fuck off.

>>8912132
It doesn't "penetrate" anything, you suppressed homosexual. It encapsulates them by providing a nice, clean, but ultimately trivial framework for constructing objects/spaces and what have you.

From Latin [math]sciencia[/math] meaning [math]knowledge[/math].

looks like you just took the science and added an ia at the end and said it means something else

>>8917702
That's the word's etymology.

>>8917640
Algebra is for fags

If you're not smart enough to ever try and learn high school math you're probably not smart enough to learn it in one summer.

But if you want to try find any online course [spoiler]Khan[/spoiler] and rush through its introductory shit like mad.
Or maybe find one of those enthusiasts on YouTube who's got hundreds of videos of them explaining the most mundane facets of arithmetic in twenty minutes.

The hardest part is gonna be retention. You'll be able to understand it no problem, but you simply don't have enough time to retain all the information.

You can always try Datura, and i've heard that malaria pills cause extreme nightmares.

>Depression pills
I'm no psychopharmacologist, but I imagine some such thing does exist. Deprive someone of serotonin and dopamine, they wont be doing too well.

No, but that doesn't make you any less of a dickhead.

Well both A and C are wrong.

C is wrong because there is no negative velocity.

A is wrong because velocity is a function of displacement from the ground and yet the graph is clearly, not a function.

The proper way to draw it would be sine wave.

How the fuck does a guy who switches from Architecture to Physics, because it was easier, become a professor?
