Specifically referring to where it says "Show that any transvection $\tau$ has the form $x\mapsto x+f(x)u$ where $f(x)$ is a linear function and $u$ is a vector such that $f(u)=0$" is this a typo?
Shouldn't it be that for any $x$ linearly independent to $u$ that $f(x)=0,$ and $f(u)\neq0?$
Or am I just missing something here?

I thought this was some sci-fi shit!
losing my marbles right now

Why do biological processes slow down when you travel near the speed of light? It's not like they're doing less work, right?

Is there any way to cure this? I really struggle with time, basic arithmetic, and a bunch of other things related to abstract numbers. I don’t think I can even fathom what an abstract number is, and I struggled in high school with it.

See how most of them arrogantly take inventions and the hard work of others(including the working class people that they deeply despise) and claim it as their own, then having the gall of saying:"Without scientists, you would not have the computer you are currently using".
The only thing scientists are doing is wasting time with garbage theories in order to feed their egos with "being smart".
This world would be better off without scientists and intellectuals, just like it would be better off without criminals.

Hello /sci/lets,

Your favorite physicist is back. I solved the "mystery" of dark matter today. What did you do today?

What would be your reactions if Superstring theory was actually proven to be true?

How are you supposed to be remembered in mathematics or physics without being born a literal god among men in terms of intellect?

Differences in Biological Function in Zero-Gravity Environment Attributable to Decreased Efficiency of Inter-Organ System Chemical Signaling Due to Decreased Variability of Fluid Accumulation; Concept for Variable Limb Pressure Therapy

Many biological functions, both those consistent with optimal health and those associated with disease expression (in genetic ailments) depend upon the interaction of genes expressing proteins in different organ systems. For these genes to express themselves, they encode proteins which, in turn, transmit messenger RNA which may interact with organ systems other than that which secreted the proteins.

For mRNA to propagate within tissue systems, it must not only be able to move through the spaces between cells through osmosis, but it must be able to enter and occupy individual cells. Many factors affect the ability of chemical signals to enter a cell, but the factor of greatest importance when assessing the differences between biological function in normal and zero-gravity environments is the force exerted by interstitial fluids against cell membranes. Where individual cells are thought generally to maintain an exact balance between internal and external pressure of fluids, under certain circumstances, external pressure may briefly exceed internal pressure. This may drive absorption and therefore diffusion of chemical signals.
