Engineers: Building Bridges But Not Relationships

Boolean logic, but make it spooky. The creator has brilliantly illustrated logic gates using jack-o'-lantern Venn diagrams. The OR gate shows features in either circle, AND shows only what's in the overlap, XOR displays what's in either but not both, NOR shows nothing at all, NAND displays everything except the overlap, and XNOR shows only what's identical in both circles. Computer scientists don't get invited to many Halloween parties, and now we know why they spend their time making pumpkin logic diagrams instead.

Nuclear meltdowns as a personality test! The meme shows corium (that molten radioactive nightmare fuel that forms during nuclear reactor meltdowns) personified as three-headed dragon. Chernobyl and Fukushima are portrayed as terrifying beasts, while Three-Mile Island is the derpy cousin who didn't quite commit to the whole "catastrophic disaster" thing. For the nuclear nerds: corium is what happens when reactor fuel, control rods, and structural materials melt together into a lava-like mass that can burn through concrete and steel. Chernobyl's version (nicknamed "Elephant's Foot") could kill you in minutes just by standing near it. Fukushima created its own hellish blend. Meanwhile, Three-Mile Island had a partial meltdown but contained most of its radioactive material—hence the goofy, relatively harmless face. Nothing says "we've mastered atomic energy" quite like creating substances that can melt through the Earth while giving you radiation poisoning through a concrete wall. Progress!

Every engineer's nightmare captured in one perfect taxonomy! The meme brilliantly categorizes screw heads based on their personality traits rather than technical specs. The Torx ("fan favorite") is actually reliable, while that slotted monstrosity was clearly "made to be hated" by someone who enjoys watching people suffer. Phillips gets the "what's your name again?" treatment because it strips faster than a magician's quick-change act. That last empty square though? Pure chaotic energy. It's the screw that exists only in theoretical engineering hell—the one that appears when you've dropped your last good fastener into the void beneath your workbench. The ultimate villain in the fastener cinematic universe.

The ultimate escalation of car salesmanship! While regular dealers are stuck in the "cargo space?" conversation (like, can I fit my groceries in this thing?), Elon Musk is out here taking the phrase literally and launching actual cars into actual space. It's the perfect punchline to the "car go road" dad joke - because why settle for roads when you can have orbit? This is what happens when you give a space enthusiast billions of dollars and nobody to tell him "maybe don't put a perfectly good Tesla in the vacuum of space." But hey, that's one way to avoid traffic!

The ultimate scientific rivalry exposed! Engineers sitting there with their functioning bridges and actual working devices while physicists mock their "close enough" calculations. Meanwhile, those same physicists are busy assuming spherical cows in a vacuum and neglecting air resistance on literally everything. The irony is delicious - like watching someone in a glass laboratory throw stones. Engineers build the real world with approximations that work, while physicists create perfect theories that only function in imaginary universes. Talk about the pot calling the kettle "approximately black"!

The magical transformation of a 50-cent production increase into "AVIATION MATERIAL" and "Aluminium and Magnesium Alloy Forging" is the marketing equivalent of turning lead into gold. Except in this case, it's turning a plastic bottle opener into aerospace engineering. Companies slap "military grade" on anything these days when the military's actual procurement standard is "whatever costs exactly $0.50 more than the absolute minimum required to not immediately disintegrate." Next time you see "military grade," just remember it translates to "we spent an extra two quarters on this thing."
