define white race.
>>800 (OP) >race Already an unscientific concept, but for the sake of discussion I'll assume the generally assumed use case. >white race Seeing as people usually define race based on geographical origin, "white" isn't a very good category for race, for the same reason "black" isn't. Americans took racism and had to boil it down to 2 or 3 groups just so their lead-raddled brains could swallow it.

Paradoxes and Facts Anonymous 10/12/2022 (Wed) 14:04:20 No. 108 [Reply] >>796
I want to learn why, when logical paradoxes exist, we can be certain proven facts are true and not logical paradoxes. I have An Introduction To Formal Logic (attached) and A Modern Formal Logic Primer (https://tellerprimer.ucdavis.edu/); will these help me? If not, what can help me?
>>108 (OP) Thanks Fren!

>>387 This proof fails since while there is a point between any two points of the bijection you never showed that it wasn't already included elsewhere. In hilberts proof he constructed a number that specifically wasn't in the bijection by shifting one of the terms of the infinite decimal expansion for each element of the bijection.
>>393 So basically a diagonal cut maneuver.

Tanis fossil site Anonymous 04/20/2025 (Sun) 23:26:04 No. 375 [Reply] >>386
I'm surprised this hasn't received wider attention. It is the nearest we'll ever get to a "smoking gun" of the KT extinction event being due to the impactor at Chicxulub. The impact created a wave in the earth's crust like you might grab the edge of a rug and flick it vertically. That wave travelled three thousand kilometres and threw huge bodies of water and mud in the air which buried an entire ecosystem. Mixed into the geologic layer are tectites with the same chemical composition as those found near to the impact site and which would have rained down within hours of the impact.
>>375 (OP) Pretty interesting. I suppose by now the Chicxulub incident is so well accepted that there isn't felt to be a need for a smoking gun. I'm gonna look this Tanis thing up now.

>>98 What are your thoughts on 4chan being down? 4chan /sci/ is already a slow board, and I don't think most of the good posters that aren't schizos haven't migrated here yet.

how do i generate curved lines that form the wheel (white line), given bordering curves(blue lines) that forms similar shape like the wheel? how do i find out its position on 2d plane/screen space and its angle,size,direction?
(29.03 KB 773x730 ClipboardImage.png)

In general or specifically this car? In general: > determine the radius of the fender > calculate with a factor (1.1 or something?) the radius of the wheel > determine the width of the wheel You know the turning point of the wheel, which is the point at which it connects to the axle. Follow standard trig functions to determine the position of the segment of wheel at a certain radius, according to the diagram in my image. The front of the rim theoretically stays an ellipse, but if you need to start fucking around with Beziér curves you might as well simulate it in blender or something. What are you trying to do?
(87.89 KB 532x549 huh.jpg)

How can you not draw a wheel? It's the easiest machine to make in the entire universe. Even planets are round, it's that generic. Basic drawing software has a circle tool. Start there.
>>91 it dont explain enough in 3d..but looks right. boy, 2021 huh >>106 yours look wrong.

I have a simple question, where was the big bang (compared to our current position)? also, if "we are in the big bang", i mean the space grow and grow, so we can be into the big bang?

how do i use math (basic or advanced) to generate a line for an object in perspective, like a drawing, that correctly represents its form in perspective?

Here ya go!If you just need one line, it's fairly simple. Just apply everything in this video to your line and you're done.
