Engineering Memes

Engineering: where theoretical physics goes to get its hands dirty and actually accomplish something useful. These memes celebrate the field where "close enough" can be mathematically quantified and duct tape is a legitimate solution in a pinch. If you've ever made something wonderfully elegant that looks like a complete mess, explained to non-engineers why their perpetual motion machine won't work, or felt the special satisfaction of a prototype that functions on the first try, you'll find your fellow problem solvers here. From the existential dread of error propagation to the joy of an elegant design, ScienceHumor.io's engineering collection honors the discipline that turns coffee into bridges, buildings, circuits, and software through the mysterious process of staying up all night with a calculator.

Ok, Just Hear Me Out...

Ok, Just Hear Me Out...
Ever had that wild moment where you realize we could solve TWO global problems at once? This genius sketch proposes the ultimate recycling hack - a factory that takes in CO₂ emissions, extracts oxygen for air tanks, and somehow magically produces diamonds on the other side! It's basically the scientific equivalent of turning your trash into treasure! Carbon under extreme pressure does form diamonds, but this "simple" solution might need a few trillion dollars and several laws of thermodynamics to bend over backward first. Still, points for creativity!

Fourier vs. Courier: When Delivery Transforms Your Package

Fourier vs. Courier: When Delivery Transforms Your Package
The mathematical genius of this pun is just *chef's kiss*! The top shows the actual Fourier Transform, which decomposes complex waveforms into their component frequencies (turning messy time-domain signals into neat frequency spikes). Meanwhile, the bottom shows what happens when a "courier" transforms your package—from pristine cardboard geometry to chaotic shambles. It's basically what happens when your carefully constructed mathematical function gets delivered by the postal service. Your elegant equation arrives looking like it was decomposed by a garbage disposal instead of a mathematical operation!

Four Ways To View A Glass

Four Ways To View A Glass
The eternal glass half-full/half-empty debate gets a hilarious academic makeover! While the optimist and pessimist stick to their philosophical guns, the mathematician swoops in with cold, calculated precision that nobody asked for. Meanwhile, the engineer is off in their own world, already redesigning the entire problem. Classic engineering solution: if something doesn't fit your needs, just declare it "overdesigned" and blame the specs. Engineers don't see problems—they see inefficient glass allocation strategies.

The Great Electron Conspiracy

The Great Electron Conspiracy
The eternal struggle of every electronics student! The top diagram cheerfully explains battery flow with dancing electrons and a cute memory aid (OIL RIG = Oxidation Is Losing electrons, Reduction Is Gaining electrons). But then our young friend has an existential crisis! "Wait a minute, isn't it supposed to be positive to negative?" Here's the zappy truth: conventional current (what we teach first) flows from positive to negative, but electron flow (what ACTUALLY happens) goes negative to positive! It's the greatest bamboozle in electrical education! Scientists just picked the wrong direction before they knew what electrons were, and now we're stuck with it forever. *maniacal laughter*

You Were Off By 3 Centimeters

You Were Off By 3 Centimeters
The precision hierarchy in science is REAL! 🔬 Biologists are horrified by a 3cm error because it could mean studying the wrong cell type entirely! Physicists look mildly disappointed - that error just invalidated months of careful experimental setup. Meanwhile, civil engineers are like "It's all good!" because hey, that bridge is still standing, right? What's 3cm between friends? And astronomers? They're THRILLED to be that close! When you're measuring things in light-years, being off by 3cm is basically perfect! That's like hitting a bullseye from another galaxy!

Furrier Transform

Furrier Transform
The genius of this pun can't be overstated! In signal processing, the Fourier Transform converts signals from time domain to frequency domain. But here, our mathematician has transformed into a furry animal—hence the "Furrier Transform." The top panel shows disappointment with regular frequency analysis, while the bottom panel shows enthusiasm for the "omega verse" (a clever double entendre playing on both the angular frequency symbol ω (omega) in Fourier analysis AND furry fandom terminology). It's what happens when engineers spend too much time alone with their equations!

I Am An Engineer Bro Trust Me

I Am An Engineer Bro Trust Me
The eternal engineering hierarchy debate in one Family Guy format! The top panel shows Meg (labeled "PROMPT ENGINEERS") having an existential crisis while screaming "ALL OF YOU THINK YOU ARE BETTER THAN ME!" Meanwhile, the bottom panel shows Peter, Lois, and Chris dressed formally as "ELECTRICAL ENGINEERS," "MECHANICAL ENGINEERS," and "CHEMICAL ENGINEERS" respectively, sitting smugly in silent judgment. This perfectly captures the engineering discipline pecking order where traditional engineering fields look down on newer digital-era specialties. Prompt engineering—the art of crafting inputs for AI systems—is the new kid on the block getting the classic Meg Griffin treatment. The traditional engineers don't even need to verbally respond; their silence and fancy outfits say everything about the perceived legitimacy hierarchy!

Integration By Parts Be Like

Integration By Parts Be Like
This is peak calculus humor right here! The integration by parts formula (∫udv = uv - ∫vdu) brilliantly represented with a UV light minus a voodoo doll. That moment when mathematical wordplay transcends into visual punnery is just *chef's kiss*. Anyone who's survived Calculus II knows the existential dread of applying this formula only to end up with an integral more complicated than what you started with. It's like the mathematical equivalent of trying to escape a labyrinth but digging yourself deeper with each turn. Pure mathematical masochism!

Fancy Energy Units

Fancy Energy Units
Look at Pooh transforming from regular to fancy when switching from joules to kilowatt-hours! It's the SAME ENERGY just dressed differently! 🔋✨ One kilowatt-hour equals 3.6 million joules - but putting on a tuxedo doesn't change who you are inside. This is basically physics showing off at parties by using fancier units when the simple ones would work just fine. Energy unit snobbery at its finest!

Fancy Energy Units

Fancy Energy Units
The elegant transformation of Winnie the Pooh from casual to sophisticated mirrors how energy units evolve in the wild. Regular Pooh represents the humble joule—the standard SI unit measuring a single newton-meter of work. Tuxedo Pooh, clearly with a physics PhD, prefers the kilowatt-hour—essentially 3.6 million joules in a fancy suit. Same energy, different social circles.

When You Can'T Solve For The Temperature, So You Decide To Just Use A Thermometer.
Content Me panic-reviewing gas law calculations at 2 AM for my 7 AM exam. Because n is constant, we can use Equation 10.8. Solve: Rearranging Equation 10.8 to solve for V2 gives ½ = 4 x - (6.0 L) 1.0 atm /252 K 295 K, = 11L 0.45 atm/ check: The result appears reasonable.

PRACTICE EXERCISE A 0.50-mol sample of oxygen gas is confined at 0 °C in a cylinder with a morade piston, such as that shown in Figure 10.12. The gas has an initial pressure of 10 at. The piston then compresses the gas so that its final volume is halt the initial volume The final pressure of the gas is 2.2 atm. What is the final temperature of the gas in degrees Celsius? 10.5 FURTHER APPLICI OF THE IDEAL-GAS EQUATION The ideal-gas equation can be used to determine many relationships involving the physical properties of gases. In this section we use it first to define the rela tionship between the density of a gas and its molar mass, and then to calculate the volumes of gases formed or consumed in chemical reactions Gas Densities and Molar Mass The ideal-gas equation allows us to calculate gas density from the molar mas pressure, and temperature of the gas. Recall that density has the units of me per unit volume (d = m/V). a (Section 1.4) We can arrange the gas equat to obtain similar units, moles per unit volume, n/V: P V RT If we multiply both sides of this equation//// @ sergM,

Measurement Error: When Unit Conversions Cost $125 Million

Measurement Error: When Unit Conversions Cost $125 Million
Remember that $125 million Mars Climate Orbiter that crashed in 1999? Yeah, that's what happens when one team uses metric and the other uses imperial. The cosmic equivalent of trying to fit a USB plug in the wrong way—except instead of flipping it three times, you lose a spacecraft. NASA engineers were probably like "Houston, we have a... unit conversion problem." Next time someone tells you unit conversions don't matter, just point to the $125 million space debris circling Mars that proves otherwise.
