was surprised to hear that most people's instinctual reaction to the trolley problem is to kill the 1 to save 5. my first reaction is: why should i intervene? i don't necessarily see how one can compare human lives as if they were objects/shekels/what have you. why not just let the situation run its natural course? how is it just that the one innocent man will be sacrificed for the 5? put yourself in the one man's shoes. i understand how in certain real-life dilemmas, you're left with no option sometimes, but the trolley problem doesn't seem that straightforward to me. take for example the Hiroshima and Nagasaki example. how was targeting civilians the most ethical option on the table? why couldn't the use show Japan the might of the nuclear bomb without killing innocents, or, at the very least, by killing soldiers/combatants. i see the problems of utilitarianism and hedonism the more outlandish your thought examples get. and yet, there are philosophers like Joshua Greene who argue it's our best bet at a meta-morality, since de-ontological approaches will always be clouded by our genetic ancestry, specific religious rulesets, and so on. he argues utilitarianism is what gave the creators the idea that slavery was wrong, and that gays/women are deserving of rights, which was clearly very much ahead of the curve compared to most of the rest of the world at the time. what think you /sci/?
Hey anons I'm looking for a job as an engineer. Seeing that in the end it doesn't really matter what field you studied in (electrical, medical, chemical, marine, nuclear, aerospace, civil, mechanical, systems, robotic etc.), we are all engineers! At the end of the day your title will be the one your company gives you based on your position. There are certain positions/sectors in a company you can fill. It's understandable that team leader and directors are paid more.
So what can you guys advise me?
>Which positions/sectors pay more? >With junior and/or senior experience? >How different is the pay between BSc, MSc and PhD (Been reading somewhere that every additional diploma can get you +34% more pay)?
Example of sectors: >Research and development
project management R&D, engineer R&D, automation >Production / maintenance:
Production technology and maintenance, production management, product engineer, maintenance management, maintenance technology >Quality / health and security:
head of quality control, quality control management, quality assurance, hygiene, environmental safety, environment >Support / applications:
commissioning technology, application technology, commissioning >Head of department:
site management, factory directorate, divisional management, production management FMEA
Was he as smart as they say or did he steal some or all of his research from the likes of people such as Poincare and Lorentz when he was working at the patent office?
3d printing some test ducts for a 50mm EDF fan mounted on a racing quad brushless motor. Will put them on a stand with a load cell and compare performance in static thrust.
Both ducts are roughly the same length and neck in to the same ID past the blades so tip losses & recirculation should be the same on both. One has a more aggressive intake and the leftover length is put into a larger exhaust nozzle. The other has a more symmetric intake and exhaust. Which one will work better? I will run tests in maybe 12h and post results if interest. Baseline to compare to is data from an off the shelf 50mm EDF.
Side note, the external geometry and its impact on vehicle aerodynamics is not going to be doing anything in a static thrust test so everything outside of the variable ID should have minimal effect on the results.
Is it possible to exploit superposition to create a discontinuous radiant flux? Reworded, can I exert a force that has holes in its momentum and motion?
Why does a nucleus form?
I'm learning about decay of heavy elements, and it occurs because the like-charge of protons will overwhelm the strong force at a large enough nuclear radii.
i can accept electromagnetism, and that things have inherent charge, and like charges repel.
is the strong force just an inherent thing? hadrons just are attracted to each other, inherently?
i guess, given a large enough sphere of protons/neutrons, obviously there's a weaker interaction between two of the most opposite protons on the perimeter of that nucleus. and given a large enough radius, the "inherent attraction" of hadrons is not stronger than the repulsion of like charges.
but, why do atoms form how they do? like, why protons and neutrons?
why is it more stable with neurons in the nucleus, than with just protons? you'd have a smaller radius and therefore a higher attractive force. why is helium-2 very unstable, but helium-4 is not?
and what of neutron stars? you can have a cohesive mass of pure neutrons. could you have a stable sphere of say, 10 neutrons or something?
>Look mom I picked a lagrangian which gave me the correct field theory after I already know the correct one!!111
Field theory, both classical and quantum, are fucking gay. Literally just sophistry with little physical or mathematical justification. Lagrangians this, action principle that, atleast for the lagrangian of a system of particles what is being done makes sense, but more often than not the lagrangians for fields are just given to you without explanation, and you're asked to minimize/maximize the action.
