Episode title or actual scientific theory:

Episode title or actual scientific theory: "The Allowance Evaporation"

Answer: Episode title!

Answer: Episode title!

In this case, "The Allowance Evaporation" has less to do with scientific limits and liquids becoming gases, and more to do with Raj's wallet.

In the titular episode, the astrophysicist's father cuts off Raj's financial support, leaving Raj to find his own way of making moola—with not-so-dignified results.
Episode title or actual scientific theory:

Episode title or actual scientific theory: "The Boltzmann Equation"

Answer: Actual scientific theory!

Answer: Actual scientific theory!

Let's be honest: Boltzmann totally sounds like the name of one of the group's outer-circle buddies. However, the equation generally relates to a fluid's behavior in various states of temperature when it's not in a state of equilibrium. This idea was first proposed by Ludwig Boltzmann in the 1870s.
Episode title or actual scientific theory:

Episode title or actual scientific theory: "The Cognitive Regeneration"

Answer: Episode title!

Answer: Episode title!

"The Cognition Regeneration" may sound like a hip, new brain-boosting fad, and this episode doesn't stray too far from that mark!

After Sheldon gets "pwned" by some youngsters in an online game match, Sheldon resolves to beef up his noodle by testing out a bunch of new hobbies that challenge his mental capacity.
Episode title or actual scientific theory:

Episode title or actual scientific theory: "The Ring Singularity"

Answer: Actual scientific theory!

Answer: Actual scientific theory!

While "The Ring Singularity" sounds like it might reference one of the gang's marriage proposal episodes—including the Season 11 premiere​—it's actually the point in space-time where the gravitational field of a rotating black hole becomes infinite. As it happens, that singularity is also shaped like a ring!
Episode title or actual scientific theory:

Episode title or actual scientific theory: "The Recollection Dissipation"

Answer: Episode title!

Answer: Episode title!

In "The Recollection Dissipation," Sheldon tries to split his time between Amy and the guys while struggling to work on two separate projects at once. Alas, the theoretical physicist works himself so ragged that he catches an awful cold—and the only cure is more "Soft Kitty"!
Episode title or actual scientific theory:

Episode title or actual scientific theory: "The Giant Impact Hypothesis"

Answer: Actual scientific theory!

Answer: Actual scientific theory!

Although he's a genius, Sheldon Cooper's brash attitude can sometimes have an enormous aftermath on those around him, so it would have made total sense for an episode to be named "The Giant Impact Hypothesis" and be all about his action's unintentional affects on his many relationships.

Alas, "The Giant Impact Hypothesis" is so much bigger than Sheldon and his larger-than-life personality. This actual hypothesis suggests that our moon was the product of an indirect collision between Earth and a massive celestial body that took place about 4.5 million years ago.

Giant impact, indeed! 
Episode title or actual scientific theory:

Episode title or actual scientific theory: "The Plimpton Stimulation"

Answer: Episode title!

Answer: Episode title!

When a renowned scientist spent the night at Leonard and Sheldon's apartment, she did much more than just stimulate academic discussion.

More interested in seducing Leonard and Raj than her scientific analysis, Dr. Plimpton laid out her research—and a whole lot more!—for a much sexier science experiment. Who said studying had to be boring?
Episode title or actual scientific theory:

Episode title or actual scientific theory: "The Beta Test Initiation"

Answer: Episode title!

Answer: Episode title!

This one was an episode of firsts for Penny, Leonard, Raj, Sheldon, and Amy.

After working out a few bugs, Penny and Leonard decided to reboot their relationship, while Raj learned he could talk to a woman—well, his phone's automated female voice command—without needing a stiff drink. Sheldon and Amy also took a test-drive with the debut of their "Sheldon Cooper Presents: Fun With Flags" web series. 
Episode title or actual scientific theory:

Episode title or actual scientific theory: "The Ornithophobia Diffusion"

Answer: Episode title!

Answer: Episode title!

Some people have a fear of human contact, of others touching their food, or of birds. Then there's Sheldon, who's afraid of all three.

In "The Ornithophobia Diffusion," Amy and Bernadette make Sheldon face his fear of winged animals head-on by forcing him to hang out with a friendly magpie jay. While he could hardly contain his disdain for the bird, at first, Sheldon soon fell in love with his feathered friend and he was able to cross one phobia off his list.
 
Episode title or actual scientific theory:

Episode title or actual scientific theory: "The Mixed Potential Theory"

Answer: Actual scientific theory!

Answer: Actual scientific theory!

From Penny tirelessly working to book a solid acting gig to Amy trying to convince Sheldon to be intimate with her, The Big Bang Theory characters are overflowing with potential. Believe it or not, "The Mixed Potential Theory" is not the title for an episode where Penny tirelessly tries to book a solid acting gig or Amy tries to convince Sheldon to be more affectionate.

Instead, this actual theory is often used in electrochemistry, which is the study of the chemical processes that cause electrons to move. Sadly, any further explanation would require you to take a class about redox reactions and oxidizing agents.
Episode title or actual scientific theory:

Episode title or actual scientific theory: "The Isolation Permutation"

Answer: Episode title!

Answer: Episode title!

In "The Isolation Permutation," Amy was devastated when Penny and Bernadette went wedding-dress shopping without her. Heartbroken and lonely, Amy wallowed in her sadness by playing depressing tunes on her harp. 

Thankfully, by the end of the episode, everything worked out for Amy, who snagged an invitation to look at dresses and a great pity-snuggle session out of Sheldon! Who says being blue is a bad thing? 
Episode title or actual scientific theory:

Episode title or actual scientific theory: "The Higgs Boson Observation"

Answer: Episode title!

Answer: Episode title!

This one's tricky! While the title pays tribute to the Higgs Boson Particle, which was named after a real scientist who discovered said particle, there isn't actually a Higgs Boson Theory. Instead, after learning that Peter Higgs' research could be honored with a Nobel Prize, Sheldon hired a young assistant to help him see if his own work could garner some recognition. 

As far as Sheldon's concerned, there's no such thing as too many accolades.
Episode title or actual scientific theory:

Episode title or actual scientific theory: "The Germ Theory Denialism"

Answer: Actual scientific theory!

Answer: Actual scientific theory!

With how often Sheldon gets sick—and how horribly he handles it—"The Germ Theory Denialsm" would totally make for a fitting and hilarious episode title; but, alas, this phrase never flashed during the opening credits of The Big Bang Theory.

Instead, it's made its way into science classrooms and textbooks around the world, and suggests that, despite popular opinion, germs don't actually cause infectious disease.  

 
Episode title or actual scientific theory:

Episode title or actual scientific theory: "The Proton Transmogrification"

Answer: Episode title!

Answer: Episode title!

If this one fooled you, then you're not alone! 

For anyone who's ever taken a biology class, you probably know that protons are teeny particles that can be found inside of an atom's nucleus. It would seem logical, then, that there might be an actual theory about protons that undergo wild transformations. But, as it turns out, the only "Proton Transmogrification" theory out there exists on The Big Bang Theory.

In this episode, Sheldon was forced to cope with the loss of Professor Proton, while Leonard and Penny reflected on all of the changes their relationship has undergone over the years.
Episode title or actual scientific theory:

Episode title or actual scientific theory: "The Locomotion Interruption"

Answer: Episode title!

Answer: Episode title!

Full steam stop ahead!

After Sheldon was robbed on his train trip in Arizona, Leonard and Amy immediately stopped what they were doing to pick up the pant-less scientist at the police station. Then, while they were dealing with Sheldon's wardrobe malfunction, Penny decided to put her acting career on pause by landing a job as a pharmaceutical saleswoman. 
 
Episode title or actual scientific theory:

Episode title or actual scientific theory: "The Modern Evolutionary Synthesis"

Answer: Actual scientific theory!

Answer: Actual scientific theory!

While it's easy to imagine an episode centered around modern evolution—after all, over the years, most of the characters have gone through huge changes and adapted to new situations—"The Modern Evolutionary Synthesis" is actually a scientific theory. 

This particular theory pulls from multiple fields of biology to explain how organisms have evolved over time. You learn something new every day.

 
Episode title or actual scientific theory:

Episode title or actual scientific theory: "The Expedition Approximation"

Answer: Episode title!

Answer: Episode title!

In "The Expedition Approximation," Sheldon and Raj venture into the depths of the university basement to determine whether or not they could survive in a salt mine while conducting dark-matter research. Cramped together in close quarters with nothing but their thoughts and the occasional vending machine treat delivered to them by Amy, the men experienced much more than just claustrophobia as they were forced to face their personal and professional insecurities. 

Sometimes, it takes overcoming one small fear in order to unearth a much bigger one hiding underneath. 
Episode title or actual scientific theory:

Episode title or actual scientific theory: "The Separation Oscillation"

Answer: Episode title!

Answer: Episode title!

Separation can drive people to do wild things and result in shifting a relationship's balance. 

In "The Separation Oscillation," Leonard mustered up the courage to confront the woman he kissed while on the North Sea, while Sheldon struggled with his own relationship woes. Still reeling from his breakup with Amy, Sheldon filmed a scathing episode of "Fun With Flags," knowing she'd be watching. Sure, his passive-aggressive approach peeved Amy, but Sheldon went to sleep feeling confident that he could get his girl back. 

 
Episode title or actual scientific theory:

Episode title or actual scientific theory: "The Recapitulation Theory"

Answer: Actual scientific theory!

Answer: Actual scientific theory!

Sheldon does an excellent job of succinctly summarizing all the different thoughts whizzing through his brain, but "The Recapitulation Theory" isn't about him clarifying his feelings.

In reality, this theory hypothesizes that embryos undergo a number of evolutionary stages before they're fully developed and mimick the same processes their ancestors went through years ago. Isn't science fascinating?
Episode title or actual scientific theory:

Episode title or actual scientific theory: "The Helium Insufficiency"

Answer: Episode title!

Answer: Episode title!

In "The Helium Insufficiency," Sheldon and Leonard pulled out all the stops to get their hands on the notable noble gas after learning of a nation-wide shortage.

That said, it's actually a very good thing that there's no such thing as a helium insufficiency theory, considering that helium is one of the most plentiful elements out there and our world wouldn't be the same without it.
