Engineer/Mathematician/Student. I’m not insane unless I’m in a schizoposting or distressing memes mood; I promise.

So true! My mistake officer. (^ This guy’s a fed)

“Bender, be careful! Thats the ship’s diamond filament tether. It’s unbreakable!”

“Then why do I have to be careful?”

“It belonged to my grandmother.”

Dark Souls remastered. Getting cursed just before reaching a boss and having no money to buy a cure forced me to either give up, grind, or “get gud.”

I beat the boss without getting hit once. I know other people probably do that for every boss but for me that’s a big achievement since I suck at combat and video games in general.

In other news, the game is hard but beautiful and the level design is pretty impressive. I’m looking forward to marathoning the other souls games after this.

Just because I’m an engineer doesn’t mean I’m autistic!

I mean, I am autistic.

But not because I’m an engineer!

hihi24522,

Same lol. Had three group assignments last semester, not fun.

hihi24522,

I second what the others are saying. 3D printing doesn’t have too much to do with ME besides being another manufacturing technique. Kind of like asking “what is the fastest way to learn mechanical engineering now that CNC is available.” Sure both of those can make manufacturing easier or even make it possible to manufacture geometries that would have otherwise been impossible, but the fundamentals of ME will remain unchanged.

In answer to your question I, like the other comments, would recommend trying to understand calculus since it shows up everywhere.

Next, I think learning basic physics and drawing free body diagrams would be especially helpful. Seriously, free body diagrams seem to be the foundation of ME.

Learning basic manufacturing (3D printing comes in here) is also vital because if you design things that work but can’t be manufactured then what good are they?

Going a bit farther in depth on material science like FCC vs BCC crystal structure and metal phases and shear planes is also useful especially if you want to study or work with specialized materials like superalloys.

You’ll need to know basic thermodynamics and fluid mechanics. You’ll need to learn how to create engineering drawings and use CAD software.

You’ll need some electrical engineering basics too. Lots of mechanical devices use microprocessor so getting experience with those is also useful especially if you want to go into robotics or mechatronics (does robotics fall into the category of mechatronics or is it kept separate?)

There’s a lot to learn and the best way to learn it all is going to be through getting a degree. There are wayy too many important things to learn before becoming a mechanical engineer than can be summed up in a simple list. Usually it’s summed up in textbooks that are several hundred pages long. Buckling modes, fatigue cycles, bolt failures, are all pretty important, like human-lives-at-stake, important but they take time to learn and use in practice.

It’s probably not going to be that fast, but that’s kind of the point. (You wouldn’t want to fly in a plane designed by an engineer who wasn’t thorough.) Hopefully a good college will give you lots of hands on experience so you know where to apply what you’re learning.

On a different note. If you can’t pay for school or you just want to learn ME for fun (I mean who doesn’t want to build cool machines in their free time?) I’d say the best way to learn is to look up what you have questions about. Find something engineered that you think is cool and try to learn why the engineer built it the way they did.

Want to build a robot to clean your desk but don’t know anything about PWM or microcontrollers or basic circuits? Chances are someone has already built something similar that you can analyze. Hell, they might even explain exactly why they did what they did. And if you catch a word or topic you don’t understand, look it up. The answers to your questions are probably out there in the internet somewhere.

Learning like this won’t teach you everything (and will not be adequate to get professional engineering certification) and it still probably won’t be fast, but it should teach you the basics of what you want to know which… well, is what you want to know right?

hihi24522,

I think chirality is something most people overlook in those situations too. Even if you found a world of beings exactly like you, a perfect earth with plants and low CO2 concentrations, if their proteins have opposite chirality to yours, you’re probably going to die of prion disease.

“Oh look a perfectly human person on an earth like planet I’m sure I can take my helmet off”. Nope. You just inhaled spores or skin cells or pollen or viruses or literally anything that contains “misfolded proteins” and if any of those get at all digested they could cause your body to produce more misfolded proteins, a cycle that will eventually lead to your demise.

“Look this plant isn’t poisonous” chirality is harder to check than chemical makeup. So yeah it has vitamin B but is it the kind that could kill you? (We don’t have to worry about this much on earth because basically all life on this planet makes and uses proteins of similar chirality)

“Wow that alien sex was great” too bad there were skin cells in saliva you both exchanged/ingested (or proteins in other bodily fluids) so you’re both going to die now.

Worst part is that prions are really slow acting. You could all be chilling in this wonderful earth like home for months until around the same time you all suddenly get sick and die. There’s no cure, so there’s nothing you can do besides leave a warning for the next crew who might stop by.

Oh and the same dangers go for native life on the planet too. To them you’re made of misfolded proteins so any scavengers who eat you and maybe even predators who eat them have a chance of developing and spreading prion disease. Your bodies are basically bioweapons. Any earth crops or animals you brought with would be biohazards too.

hihi24522,

Was it that one episode of Hannibal where the guy grows mushrooms on diabetics he keeps in comas in the forest?

hihi24522,

Not that anyone cares but I just realized that this is not actually paradoxical and I can prove it mathematically! (I think) Bear with me since I’ve like just barely learned this stuff this week.

Proof Let S be the set of all steps needed to be taken. It can be written as S = {(distance to be traveled)(2^-n^): n in the Natural numbers}. Thus, S shares cardinality with the natural numbers and is countably infinite.

However, time is continuous. Thus, it has the cardinality of the continuum (real numbers) which means any time interval contains an uncountably infinite amount of moments. Let us denote an arbitrary time interval as T.

Because | T | > | S | there is no injection from T to S. Thus if each step has only 1 time value, there will be moments of time left over, and since the hand is not in two places at once we know each step must have its own time value, so this must be the case.

Therefore, when moving in steps like this, one will run out of infinite steps before they run out of moments in time to complete those steps. Hence, any finite distance can be traversed in this way over some bounded interval of time. QED.

Basically, you can traverse any distance in any time interval as long as physics allows you to move at a fast enough speed. Even if it doesn’t, there may be a limit to how fast you can traverse the distance, but it is still bounded. You can traverse any finite distance like this before existence runs out of time.

(I’m still learning. So if there’s an error in my proof please be gentle lol)

hihi24522,

Yes, but if the universe is quantum, then there also exists a minimum finite space step. So the fractions never get infinitely small. So you either stop moving in which case of course you never reach the destination; you stopped before you did. OR you take an extra step and surpass your distance by a negligible amount which means you did move all the way.

So even in a quantized universe, the paradox is still false right?

hihi24522,

Allegedly

hihi24522,

Can’t catch me if I’m 5 parallel dimensions ahead of them! (5D chess with multiverse time travel)

I had no idea Romans laid eggs lol

Never read The Great Gatsby?
