Wave your hands in the air like you 're a mathematician

AI Thread Summary
The discussion centers around a posted graphic that depicts various mathematical functions represented through human-like figures. Users identify several errors in the representation, noting that the graphs for 1/x and -1/x are incorrect but can be interpreted creatively. It is pointed out that the graph for sin(x) actually resembles -sin(x), and the hands of tan(x) and cot(x) should be oriented vertically rather than appearing to deflect. Additionally, the logarithmic function log_a(x) is criticized for being inaccurately depicted, suggesting that the figure needs to adjust its posture for y=a^x. Overall, the conversation highlights the need for clearer and more accurate representations of these mathematical functions.

I posted this on our facebook wall awhile back and a few said there were errors. Can anyone find them?
 
It looks like 1/x and -1/x are incorrect, but if you use your imagination they work. I think the others are all good though.

edit: actually sinx is a graph of -sinx

The hands of tan x and cot x should be pointing up/down. Instead they look like they're deflecting (although the left hand of cot x looks OK).

\log_a(x) is way off.
 
Needs to dislocate his shoulders more for y=a^x. Some of those look quite painful for anyone who isn't some kind of tentacle monster.
 

Thread 'Predictions for the Nobel Prize in Physics 2025'

Similar to the 2024 thread, here I start the 2025 thread. As always it is getting increasingly difficult to predict, so I will make a list based on other article predictions. You can also leave your prediction here. Here are the predictions of 2024 that did not make it: Peter Shor, David Deutsch and all the rest of the quantum computing community (various sources) Pablo Jarrillo Herrero, Allan McDonald and Rafi Bistritzer for magic angle in twisted graphene (various sources) Christoph...

Thread 'My experience as a hostage'

I believe it was the summer of 2001 that I made a trip to Peru for my work. I was a private contractor doing automation engineering and programming for various companies, including Frito Lay. Frito had purchased a snack food plant near Lima, Peru, and sent me down to oversee the upgrades to the systems and the startup. Peru was still suffering the ills of a recent civil war and I knew it was dicey, but the money was too good to pass up. It was a long trip to Lima; about 14 hours of airtime...
