The True Heir To The British Throne

This flowchart is what happens when career counselors have a mental breakdown. Engineering? Only if you're "good with things." Chemistry? Congratulations on your future as a "fussy pedant." And let's not forget Computer Science, perfect for those who prefer "slow, indirect evil" over the more efficient varieties. The beautiful part is how it nails the existential crisis of every STEM student. "Why do you want to major in a STEM field?" Options include "curiosity" (adorable), "to save the planet" (delusional), or my personal favorite, the dawning realization that STEM was supposed to involve actual plants for Biology majors. After 30 years of teaching, I can confirm this is approximately 87% accurate. The missing 13% is the path where you choose your major based on which department has the least uncomfortable chairs in the lecture hall.

The scientific hierarchy in all its puppet-mastering glory! Math sits at the top pulling the strings of Physics, who controls Chemistry, who manipulates Biology, who yanks around Psychology, who's probably controlling some poor undergrad we can't even see. This is the academic food chain that no professor will admit to but secretly knows is true. Pure mathematicians love nothing more than reminding everyone they're the puppet masters of all science—right before they fail to calculate a proper tip at dinner. The irony is exquisite.

That moment when your biochemistry knowledge fails you spectacularly! Melatonin is the hormone that regulates sleep cycles, while melanin is the pigment that determines skin color. Mix those up and instead of a peaceful night's rest, you've just given yourself an unexpected pigmentation boost. The body's response? Pure panic. Next time, maybe read the bottle twice before self-medicating after that 3 AM grading session. Chemistry professors aren't immune to molecular mix-ups either!

Ever notice how viral diseases have their own PR teams? HIV/AIDS has been the OG pandemic villain for decades, but then COVID-19 swoops in with its fancy media coverage and suddenly it's the hot new threat! The hilarious truth bomb here is that while both are serious viral threats, COVID got the spotlight treatment with 24/7 news cycles, while HIV/AIDS continues its devastating global impact with way less headlines these days. Fun fact: HIV has infected ~76 million people since the epidemic began, while COVID infected over 760 million in just its first three years! Different transmission methods, different media frenzies, same scientific challenge of battling viral enemies that keep evolving to outsmart us!

The eternal scientific rivalry captured in muscular arm form. Physicists and chemists can agree on exactly one thing: their mutual disdain for biology. They'd rather calculate the quantum state of every electron in the universe than memorize the Krebs cycle. The irony? They're all just studying different scales of the same reality. But don't tell them that—they've got lab equipment to passive-aggressively borrow from each other.

The cellular equivalent of "it's grabbin' time." Actin filaments are protein structures that normally mind their business maintaining cell shape, but add calcium ions (Ca2+) to a muscle cell and suddenly they're contractile celebrities. The hands reaching for those emoji faces perfectly capture how these filaments frantically grab myosin during muscle contraction—nature's microscopic tug-of-war that lets you do everything from blinking to benchpressing. Next time your muscles twitch involuntarily, just remember: your actin filaments got a little calcium-happy.
