applefaced

referencing the rosy apply cheeks of someone blithe, too naïve to appreciate life's pain, or unaware of it, and so they're always smiling and cheery

'I'm so upset, man, my parents are getting divorced,'
'Hey, cheer up pal! You'll be all right!'
'Jesus man, you're an applefaced fool.'

Applefeld

If somebody has the last name Applefeld it means they are a godly creature to good for this planet. They are extremely intelligent and perfect in physique. They do not have enemies because everybody just loves them. If you are friends with an Applefeld you are one of the luckiest people alive. They also have superhuman powers which is another reason they are superior to other humans.

“The Applefeld’s are the true overlords of the human race”

When a man ejaculates into his hand and wipes it on said partners body

Ahh dude... I was out on the weekend and applied-cummery on his/her face.

Applied Game Theory

Using game‑theory models to explain real‑world politics, economics, and social behavior. Jiang strips away the abstract math and applies concepts like the prisoner’s dilemma, zero‑sum games, and Nash equilibria to everything from dating to nuclear brinkmanship. The idea is that if you can figure out the “payoff matrix” of any situation, you can predict—and even manipulate—the choices of the players. It’s strategy for geeks who want to rule the world.

“Applied Game Theory explains why the U.S. and China are stuck in an arms race: it’s a classic ‘security dilemma’ where neither side can back down without looking weak. Spoiler: the only winning move is to change the game.”

Applied Thermodynamics

The use of thermodynamic principles to design, analyze, and optimize real-world systems—engines, refrigerators, power plants, chemical processes, and even electronic devices. It's the engineering workhorse that takes the abstract laws of energy and makes them build things, calculating efficiencies, losses, and feasibility to turn heat into motion, cold, or electricity.

Example: "The applied thermodynamics exam was brutal: 'Design a Rankine cycle for a geothermal plant with these brine temps, calculate the turbine work output, and sketch the T-s diagram.' For the rest of us, it was hieroglyphics. For them, it was the blueprint for pulling power from hot rocks."

Applied Game Theory

The use of game theory’s mathematical models—which analyze strategic interactions between rational decision-makers—to solve real-world problems in economics, business, politics, and biology. It moves beyond the textbook “Prisoner’s Dilemma” to design auctions, negotiate treaties, price products, or even schedule airport security checks. Practitioners don’t just predict what players will do; they design the rules of the “game” itself to incentivize better outcomes, like creating a market that naturally reduces pollution or a contract that aligns an employee’s interests with the company’s.

Example: “The city used applied game theory to fix traffic. Instead of just adding lights, they made each traffic signal an ‘agent’ in a game, rewarded for keeping cars moving on its road but penalized for creating gridlock on intersecting streets. The signals started cooperating, learning to form ‘green waves.’ They didn’t just react to traffic; they played a city-sized game of optimization and won.”
