I learned about Young’s modulus and Eddy currents in school last year. Used to watch BBT when I was 10-13 but now I feel so proud when I know what they were talking about.

Aerospace engineer here. Fluid mechanics is one of the major area we need to be fluent in. The entire concept of flying is dependent on it (aerodynamics is just a subset of fluid dynamics) . We ought to learn a bit of electronics, control systems, structural engineering and instrumentation.

[@vote4dahv411]

Aerospace engineers would care about air flowing through a pipe if they're trying to design an aircraft to fly at speeds greater than Mach 1 where air flow needs to be compressed enough to achieve efficient burn rates in the engines. Examples include the F-35, F-22, Ramjet rockets, Scramjet Rockets etc.

[@killugonzolfreecss5355]

You're surprisingly on point with the teaching part. See, what many people don't understand is that in teaching knowing the subject material is one thing but imparting that knowledge is another skill altogether. Generally, while an engineer would probably know more about something like steam engines or electrical circuits than us, but those of us with actual teacher training (even more so if they are veterans of the field) would have a better chance at imparting our knowledge and fixing whatever parts that a student is missing I always argue that when it comes to professionalism, teachers are on par with engineers, doctors, and lawyers in terms of professional ability, except our specialization would of course be on education

I think the flow of liquid is directly proportional to the radius cubed

[@adamjohannesson3434]

The brachistochrone problem was one of the earliest problems posed in the calculus of variations. Newton was challenged to solve the problem in 1696, and did so the very next day (Boyer and Merzbach 1991, p. 405). In fact, the solution, which is a segment of a cycloid, was found by Leibniz, L'Hospital, Newton, and the two Bernoullis. Johann Bernoulli solved the problem using the analogous one of considering the path of light refracted by transparent layers of varying density (Mach 1893, Gardner 1984, Courant and Robbins 1996).

[@lawrencewestby9229]

The brachistochrone is the curve of fastest descent from point A to point B where point A is higher than point B and the two points are horizontally offset assuming uniform gravity and frictionless environment. For a 9th grade math fair, with a little tutelage from my older brother, I built a marble race where one lane was a linear slope and the other a cycloid, complete with starting gate and finish gate, to show that the curved path was the faster (friction was ignored due to the short length of the track). Unfortunately, my geometry teacher probably had no clue what it was and I got a B+ while electronic quiz boards got A-'es. The physics teachers loved it though.

There also seems to be this battle between software and hardware engineers at most places too. One side argues that without the hardware, the software has nothing to run on while the other says without the software the hardware is just parts. It's crazy because this happens inside the same company. It divides more often than unites and often becomes petty in nature.

[@alwaysonyourtail2563]

the engineers job is mostly done by the time the physicist is done dreaming up his idea and sends a blueprint to the engineer. the engineers job is mostly to try to think why the machine would fail and send it back for a redo. the program or cycles of the gears is already completed by the math guy. without him the machine would break under its own power over and over using the physicist first is very much cost effective. so in the end the physicist does the hard work of dreaming and doing the math while the engineer follows the design both are important but the math was harder.

[@nowthatisawesome5431]

You kept questioning why Sheldon would need to know engineering. It’s not about that, so I think you missed the point. Sheldon kept telling Howard that he wasn’t smart enough to take his physics class. Howard’s defense was that asking him questions regarding a topic he’s unfamiliar with doesn’t mean he’s not smart, and that he could do the same thing to Sheldon. Sheldon then said “try me” which is why Howard began asking him engineering questions to prove that Sheldon doesn’t know everything. Sheldon is an egotistical know-it-all who is constantly putting others down and insisting that he is smarter than everyone else around him.
