my astronomy professor assigned us this essay over thanksgiving break and I'm completely drawn a blank. Can any of you help strike up some ideas for me to talk about comets or asteroids because I have no idea how I'm going to write 3 pages about them.

>ask a math who completed his undergrad if he knows what modus ponens is
>"Nope"
>What about sequential calculus / basic symbolic proof?
>"No"
>show him a basic example of the use of basic inference rules
>he says he never encountered this

Are math programs really this shitty? Should I stay in CS? How the fuck do math undergrads do proofs if they don't even know what they mean and correspond to?

I've heard that 85% of succeeding in getting a job and working in STEM is due to social skills, which is quite little compared to other fields. Is this true? Is being able to get along with people more important than being able to solve problems?

This is the Serpentine Tower a puzzle tower from a very old MMO that has remained unsolved for 10+ years now.

I'm here to ask about one of the books in the tower as far as I know no one has managed to translate it. Is there a way to prove absolutely if this message contains real information or if it is just rubbish added for color? As far as I can tell it is unlikely to be something like OTP. Also from the history of the game they did use an in game "orc language" players had to use prior to the creation of this tower in 2004.

If it can be ruled out as rubbish then it is one less thing to worry about in the overall puzzle. Will copy the full text of the book below.

Any real engineers here? Can anyone recommend a book on gas turbine construction? Like the actual construction not just theory and super simplified diagrams. I want it for my hoverboard research. I have spent a while researching compressors and turbines and practicing drawing them with CAD software and 3D printing models so I'm familiar with that part but I'm not confident about the rest of it. Major gaps in knowledge are the oil lubrication system and the combustion chamber. So far I've seen amateurs like myself hooking up two turbochargers and for the combustion chamber they always punch "flame holes" of increasing size but I don't understand why that allows stable combustion.

14 year old Lucas Etter has set a new world record for completing a Rubiks cude: 4.904 seconds, 0.35 seconds faster than the previous record.
He set it as the River Hill Fall competition in Clarksville, Maryland.

Speedcubers get 15 seconds to inspect the cube before attempting to solve it.

The world Rubik’s cube championship has taken place every two years since 2003, and world records – first set at 22.95 seconds by 16-year-old Minh Thai in 1982 - have been nimbly demolished ever since.

If a schizophrenic could use math and logic to get rich as fuck, why haven't you?

>When Sartory retired in 1992, he shut himself in a tiny apartment and used algorithms to invest on Wall Street. The savant built a $14-million portfolio before the stock market crashed last year, records show.
