I remember reading a sci-fi book, and a plot point was a machine that could turn a 3-dimensional object around in hyperspace, turning something left-handed into something right-handed
It was supposed to be useful in surgical replacements of limbs, etc.
But then I had a hard time suspending disbelief because all the proteins, DNA, etc. in the flipped tissue would also be its own chiral opposite
None of the enzymes would work
It wouldn't be able to metabolise anything
@acciobooks So imagine you have a 2-dimensional figure in a plane, say it's a lower-case "b"
You can move it anywhere you like on the plane, or even rotate it, but you can't pick it up
So you can turn it so that the long stroke of the "b" is on the bottom and the loop is pointing up rather than to the right
But you can't turn it so that it looks like a "d"
To do that, you'd need to take it out of the plane
Similarly with 3-dimensional figures and hyperspace
@bgcarlisle Neat, thanks!
Scholar Social is a microblogging platform for researchers, grad students, librarians, archivists, undergrads, academically inclined high schoolers, educators of all levels, journal editors, research assistants, professors, administrators—anyone involved in academia who is willing to engage with others respectfully.
We strive to be a safe space for queer people and other minorities, recognizing that there can only be academic freedom where the existence and validity of interlocutors' identities is taken as axiomatic.

Scholar Social features a monthly "official" journal club, in which we try to read and comment on a paper of interest.
Any user of Scholar Social can suggest an article by sending the DOI by direct message to @firstname.lastname@example.org and one will be chosen by random lottery on the last day of the month. We ask that you only submit articles that are from *outside* your own field of study to try to ensure that the papers we read are accessible and interesting to non-experts.
