Should It Be Youler And Youclid?

Behold, the Pythagorean sandwich theorem. Scientists have been suspiciously quiet about this groundbreaking discovery that diagonal cuts increase sandwich volume without adding ingredients. The perimeter length of a diagonal cut (√2 × side length) is indeed greater than a straight cut (1 × side length), creating the illusion of "more sandwich." Of course, conservation of mass still applies—you're just redistributing the same amount of bread and fillings into triangles instead of rectangles. But try telling that to your brain when you're hungry at 3 AM in the lab.

The number 68 is missing, but that's just the tip of the mathematical trickery! This meme is the equivalent of setting a pattern recognition trap for your brain. You frantically scan the sequence looking for the gap, while your inner mathematician screams about numerical continuity. The real genius? Most people get so focused on finding the missing number that they don't notice there's a duplicate 53 in there! Mathematical pranks are the ultimate form of nerd warfare - weaponized number sequences designed to make you question your sanity and counting abilities simultaneously.

The math gods have spoken! This meme brilliantly captures the pain of approximating the sine function in calculus. The top shows the full Taylor series expansion of sin(x) with all those terrifying terms going to infinity. But then Lord Farquaad (math professor energy) declares "Some of you may die, but that's a sacrifice I'm willing to make" - and suddenly we're left with just the first three terms! 🔥 This is basically every math class ever: "Don't worry about those higher-order terms, they're negligible for small values of x." Meanwhile, the accuracy of your calculations quietly weeps in the corner. The truncated series is actually the small-angle approximation that engineers use while mathematicians judge them silently from afar.

The WKBJ approximation is to quantum physics what group projects are to students - nobody remembers who actually did the work. This textbook snippet brilliantly captures the academic equivalent of "I made this" meme, where hands labeled W, K, B, and J form a solidarity circle while explicitly noting they did NOT invent the method named after them. Meanwhile, the footnote lists about a dozen physicists who actually contributed to it over 136 years. Graduate students everywhere just nodded knowingly while calculating their tunneling probabilities.

The guy's not wrong. The Zeroth Law basically says if A = B and B = C, then A = C. It's like discovering your coffee mug is the same temperature as your desk, and your desk is the same temperature as your keyboard, so—shocking revelation—your coffee mug is the same temperature as your keyboard. Physicists really spent centuries figuring that out and then had to awkwardly insert it as the "Zeroth" law because they'd already numbered the others. Classic scientific numbering crisis. Next they'll tell us water is wet.

Content If the proof of a theorem is not immediately apparent, it may be because you are trying the wrong approach. Below are some effective methods of proof that might aim you in the right direction. Proof by obviousness: "The proof is so clear that it need not be mentioned." Proof by general agreement: "All in favor?.. Proof by imagination: "Well, we'll pretend it's true. Proof by convenience: "It would be very nice if it were true, so.. Proof by necessity: "It had better be true, or the entire structure of mathematics would crumble to the ground." Proof by plausibility: "It sounds good, so it must be true." Proof by intimidation: "Don't be stupid; of course it's true!" Proof by lack of sufficient time: "Because of the time constrait, I'lI leave the proof to you." Proof by postponement: "The proof for this is long and arduous, so it is given to you in the appendix." Proof by accident: "Hey, what have we here?!" Proof by insignificance: "Who really cares anyway?" Proof by mumbo-jumbo: Wo ф, 3,830*8=8, Proof by profanity: (example omitted) Proof by definition: "We define it to be true.! Proof by tautology: "It's true because it's true." Proof by plagarism: "As we see on page 289,..." Proof by lost reference: "I know I saw it somewhere....' Proof by calculus: "This proof requires calculus, so we'll skip it." Proof by terror: When intimidation fails Proof by lack of interest: "Does anyone really want to see this?" Proof by illegibility: E GED Proof by logic: "If it is on the problem sheet, it must be true!" Proof by majority rule: Only to be used if general agreement is impossible. Proof by clever variable choice: "Let A be the number such that this proof works.." Proof by tessellation: "This proof is the same as the last." Proof by divine word: " And the Lord said, 'Let it be true, and it was true Proof by stubbornness: "I don't care what you say- it is true." Proof by simplification: "This proof reduced to the statement I + 1 = 2." Proof by hasty generalization: "Well, it works for 17, so it works for all reals." Proof by deception: "Now everyone turn their backs. Proof by supplication: "Oh please, let it be true. Proof by poor analogy: "Well, it's just like...' Proof by avoidance: Limit of proof by postponement as it approaches infinity Proof by design: If it's not true in today's math, invent a new system in which it is. Proof by authority: "Well, Don Knuth says it's true, so it must be!" Proof by intuition: "I have this gut feeling.
