Out-of-Bounds Calculus

Unexpected or surprising examples, interesting problems, and clever proofs on calculus that are often counterintuitive or paradoxical—the oddities that most math students are seldom exposed to during their calculus lessons.

Be it a continuous function whose graph possesses a tangent at no point, or a continuous function that has infinitely many maxima and minima on a finite interval, or a shape that has finite area but infinite perimeter, these examples of out-of-bounds calculus seldom fail to trigger an aha! reaction among math geeks.

Covid-👽

When conspiracists or hoaxers claim that the coronavirus is dead scared of aliens, ghosts, or spirits, which means that someone is safer in the presence of these dark or evil forces.

A number of diehard QAnonists refused to wear any masks at Halloween parties because of their pseudoscientific Covid-👽 beliefs.

Pi Apparition

When the ghost or spirit of the number π would appear to some lucky mathematicians or math educators to reveal to them some of her sexy numerical, geometric, or trigonometric properties—when they least expect her to visiting them, while experiencing an aha!

Unlike demonic apparitions that petrify even diehard Proud Boys “patriots,” pi apparitions are welcomed by both the mathematical brethren and the numerological fraternity.

COVID-(19+X)

The next pathogen that could decimate humanity if mankind is not preparing for it, which is predicted to hit the world X years after COVID-19.

With the ravages caused by Covid-19, astrologists, biblical numerologists, and epidemiologists are hell-bent to predict, divine, or model when COVID-(19+X) would occur.

C—O—V—I—D-19

When corona-infected patients are still experiencing lingering symptoms such as brain fog, fatigue, and inflammation and injury of major organs such as the lungs and heart long after they were tested negative.

For the majority of Covid-19 patients, the symptoms would disappear after a fortnight, but for a small group of C—O—V—I—D-19 or long Covid patients, their persistent symptoms are taking a toll on their mind and body, leaving them and their doctors confused and confounded.

Corona Equation

A numerical statement that exposes the cause for the high number of infections and fatalities in a country, which is often due to the actions (or inactions) of a fake or inept head of state and the failure of his semi-skilled administration in containing the coronavirus pandemic.

A corona equation expected to hold true on 1/20/21—the last day of Donald J. Trump at the White House—is: 🤥₄₅ + 🦠₁₉ = 24M 😷’s + 400K 💀’s.

Covid-🇵🇭

When Catholic priests in the Philippines, who link Covid-19 with the devil’s work, are using exorcism to fight the coronavirus, by using a cross, holy water, and holy salt as their deadly spiritual weapons.

Due to Covid-🇵🇭, besides conducting services for families whose loved ones had died of Covid-19, priests are risking their lives by going around exorcizing funeral homes, with some of them even telling families to refrain from being inoculated because some approved vaccines were produced from aborted fetuses.
