That's the thing with vocationals skills - they make you really good at understanding how something works or how to fix something without breaking something else, but beyond that range of problems and solutions, you need to talk to an engineer.
Not that vocational jobs are not important - clearly they add value and create employment.
- WalterBright 5y agoI'm not so sure they understand how it works, though. BTW, if you ever see an EE with a card that has printed on it: V = I*R I = V/R R = V/I it's a sure sign he's a formula-plugger, and has no idea how it works. He doesn't even understand algebra. https://testguy.net/content/266-Ohm-s-Law-Watt-s-Law-Cheat-Sheet https://testguy.net/content/266-Ohm-s-Law-Watt-s-Law-Cheat-S... A definite no-hire :-/
- hellbannedguy 5y agoThere's a book called, Everytjing I should have learned in Engineering School, but didn't. I had no idea there were EE's walking around who were rusty with basic electrical formulas.
- WalterBright 5y agoShocking, isn't it!
- blippage 5y agoHopefully it's just a current trend.
- jack_riminton 5y agoThey just take the path of least resistance
- dempseye 5y agoGo on. Take the upvote.
- geomark 5y agoMy kid accused me of that. I grounded him. Edit: Ah, come on! That's one of my best jokes and I got downvoted?!
- dotancohen 5y agoMaybe the downvoters were not convinced that insulating your kid was a good idea.
- neutronicus 5y agoOr perhaps they're concerned it will short-circuit his development
- wiredfool 5y agoYeah, it would be E=IR
- exporectomy 5y agoBecause proper EEs draw it in a triangle instead? https://upload.wikimedia.org/wikipedia/commons/5/5f/Ohm%27s_law_triangle_%28VIR%29.jpg https://upload.wikimedia.org/wikipedia/commons/5/5f/Ohm%27s_...
- WalterBright 5y agoOhm's Law is the first lesson in an electronics set for kids. https://generalatomic.com/teil1/B.html https://generalatomic.com/teil1/B.html Proper EEs don't need a cheat sheet for it.
- pitched 5y agoI’m not saying that most people aren’t formula pluggers (and that’s a big problem) but, my first impression of that kind of card would be that’s it’s meant to be branding, not a tool. Someone is carrying around a piece of what they love.
- WalterBright 5y agoIf you want to brand, print Maxwell's Equations on the card. Or put a simple amplifier circuit on it. P.S. Maxwell's Equations on a t-shirt are popular, I even sold one for a while.
- pitched 5y agoJust out of curiosity (I don’t mean this to be a dig and don’t carry either cards), why are Maxwell’s Equations good but Ohm’s Law is an instant no-hire? How I remember the story is that, when Ohm published his equation, it came as a huge shock because no one was expecting it to be so simple. There’s a lot of beauty in that simplicity. Maxwell’s equations aren’t that complex but they aren’t exactly _linear_. Valuing complexity is an interesting hiring tactic but would probably be a great filter on younger engineers?
- WalterBright 5y ago1. Ohm's Law is taught the first day of 4 years of an EE degree. Ohm's Law should be part of your soul, not something a cheat sheet is needed for. 2. The 3 versions of the formula are obvious to anyone who remembers high school freshman math. It's barely even algebra. Carrying that cheat sheet signals you know neither electronics nor the most basic algebra. Maxwell's Equations, however, get introduced in 2nd or 3rd year in college. You'll need a year (probably two) of calculus to even understand the notation. The equations unify the theories of electric fields and magnetic fields. Only people who have studied Maxwell's Equations will even recognize them, so by putting them on a t-shirt you're signalling that you are an educated EE to other educated EEs. Other people won't even know what they are. https://en.wikipedia.org/wiki/Maxwell%27s_equations https://en.wikipedia.org/wiki/Maxwell%27s_equations
- WalterBright 5y agoDownvote me all you like :-) but if you're an EE and carry such a cheat card, I'd keep it out of sight. I'm not the only one with that opinion.
