This is why I love Engineers

[@kyrman6038]

A mathematician, a physicist and an engineer are all tasked with measuring the surface of an irregular rubber object. The mathematician breaks the object up into different geometrical forms, measures it and sums it all in a series of equations. The physicist uses a combination of archimedes principle and shadow optics to get the volume and trace the outline of the object in a number of different positions then approximates the surface area in a sum. The engineer looks up the manufacturer's manual and reads the exact surface area directly.

That a good one, thanks.

[@AngryArmadillo]

After being unable to find the right spec sheet, the engineer dips the object in a vat of paint, and measures the weight of the vat before and after.

[@skachor]

Personally, I'd dip it in water and find the volume and hope nobody noticed

"in this book that i bought, ahem." Sale at the archive.

[@lkapitan8232]

I actually do own a hard copy of this book, but found this PDF copy on a Russian website, of course, so I could make the video.

​@@lkapitan8232 Could you... you know... tell us this russian site

I was just randomly scrolling and youtube recommended me this video and I enjoyed it and then I went to sleep so im probably sleeping right now or its the next day, very very nice

[@peperomero4603]

i just read this. im gonna watch the video and go sleep

[@lkapitan8232]

Thanks for watching and I wish you good sleep

[@Tommy-gc7us]

I too was randomly scrolling to this KZbin reccomendation and I’m currently sleeping right now. I’m sleeping

[@efenestration]

did you wake up

[@Nah_Bohdi]

Im the video, youre not scrolling, this is awake.

love seeing excerpts of books like this! thanks for sharing :]

[@alphago9397]

yup; it takes a special kind of attention to detail to love engineering.

[@IIAOPSW]

I will never forget the vector calculus professor I had who was talking about flux through a quarter cut of a spherical surface, and told us very bluntly and with a thick Asian accent to "integrate through Jew hat". The demographics of the room, being what they were, understood the shape he was talking about instantly and did not ultimately object to this manner of description.

[@Speed001]

At first i was thinking, oh no, what did the engineer do. The mathematican does the logical thing, use the formula for a helix. But by the time we reached the end, the engineer did the obvious thing. Model and measure. Really shows the advantage of the 2 methods. Technical analysis and Rapid prototyping. Scientific method for what we understand vs Empirical method for what we don't.

Randomly found this video on my recommendation page. I’m 18 years old, and for the first time, I’m in an engineering National graduate school in Morocco, first year. Going from school to national graduate school, things went from 0 to 100. I find everything difficult, and sometimes I question myself what I was thinking signing up for this university. when I review my subjects, I find it difficult paying attention even though I’m very intentionally trying to pay attention, but every 5 seconds, I zone out. I thought I’d seek an advice here knowing a lot of other people seem to also have come across this video randomly from their recommendations page as well

[@lkapitan8232]

You are describing myself in year one college. I went from a poor high school in the mountains to a university and I was lost, poor grades, bad attitude, almost quit several times. Every time I tried to give up I thought about the rough life my parents had, father was a coal miner, mother was a waitress. I wanted more than that, so I stuck it out and it slowly got better and better and I grew up to be a scientist, got a good job, and had a great life. Find something you want to achieve and think about getting that. I wish you good luck.

Engineer and mathematician discovers generative design circa 100 B.C.

[@sheriffsatori]

I imagine it somewhat went like this... "Damnit, gotta be a bit smaller." The next day... "You know what, this is good enough. It'll do." Thanks for sharing this though, it's really nice.

[@jackobrien9864]

just did something similar in order to design a spring wound around the path of an Archimedes' spiral, easy to do if you know parametric equations, then you can just get a huge table of x,y,z values and slap that into a cad program.

[@FirstBurns]

Nice video. The helix is not for strength though. Its because of the karman effect or vortex shedding. The helix makes the smoke stack not shake itself apart in certain winds.

[@lkapitan8232]

That is interesting, now I have to look that up. Thanks

[@peepeepoopoovdbhxvbcc6683]

The eng kids at my university have the unanimous respect of every other major because of how difficult this stuff is. Especially because this is the best (and hardest) university for engineering in my country. Keep at it!

[@w花b]

Just experiment.

[@adamz8314]

next video ,why I hate Engineers

[@pedrolucas-hr7tl]

Im finishing my first year of civil engineering and can confirm this. We just opt for practical solutions

Keep up the good work

[@lkapitan8232]

Thank you.

[@RobertWill-uq3iv]

I think a lot of people don't love engineers cause they pay attention to the minutia that bores the hell out of everybody else. But this stuff is how our modern world is built. I think of myself as having an engineering mindset- it fascinates me to a further degree than most. But there are limits. I have a few copies of the magazine 'Racecar Engineering'. One issue outlined the aerodynamics of an F1 spoiler which allowed Ferrari to restore about 80% of the down force lost when tunnel cars got banned. I absolutely was unable to finish the article. It was as dry as anything I'd ever read.

[@bhbr-xb6po]

The engineers' method is not generalizable though. They'd have to futz around with a new model for each new kind of smokestack, whereas the professor can just plug new values into the same formula.

[@lkapitan8232]

I am in no way demeaning the professor, I am a scientist not an engineer. I just thought it was such a cute story how a person that had probably never heard of differential geometry came to basically the same answer.

[@mismis3153]

​@@lkapitan8232 it's a bit weird since it seems like engineering schools aren't sure whether to teach this or not. For example, I was taught this in 2nd year whereas the new programs don't teach this anymore.

[@poojapriti617]

Bro ..i was just thinking about a episode from tbbt in which leonard points out at piece of paper saying "sheldon ,this is the riemann shape whoch you got you into caltech "...and this popped out ..dayumm

How close we can get and then even closer :D

Are you using the Mega OS distro?

[@lkapitan8232]

I don't know what that means.

[@mq-r3apz291]

And yet us engineers are being trashed by the economy and corrupt college system. Thank god i can study abroad and japan is activly looking for skilled work immigrants including stem majors

[@kaynex1039]

Was probably once true, but nowadays engineers will build CAD drawings to determine this stuff.

[@therealenzyme1954]

And some engineers (the ones who actually know differential geometry and have PHDs) program the CAD software

[@miguelmendoza3403]

@@therealenzyme1954 That is my answer when people say things like that.

[@robguyatt9602]

Hardly needed a Prof of of anything to work out the helix. I did an apprenticeship in structural steel and welding in the 70s and learned how to calculate, develop and fabricate screw conveyors. This strake is the same principal. Oh and no calculus required. Just basic high school trig.

[@skachor]

A bit of a whippersnapper question for you, has apprenticeship declined as an entry to your profession? Or have you noticed any changes between the earlier days and today that you think would benefit the younger generations?

[@bernardobertamini856]

As a physics student I don't consider engineers very highly

[@ryanspence5831]

As an engineering student, you haven't even found dark matter yet so be quiet while we build you a probe to find it

[@londonalicante]

I changed from science to engineering. You know why? Scientist = starving artist. Engineer = well paid housepainter.

[@uvideo100]

There are universities which offer a degree in Engineering Physics.
