π

An irrational number that is traditionally defined with respect to the circle, such as the following:
The length of a semicircle of radius one unit.
The angle measure of a straight line segment in radians.
The number of times the perimeter of a circle is more than its diameter.

To help students appreciate π beyond the canned definition that it is the ratio of circumference to diameter, teachers ought to define it in terms of other quantities not related to the circle.

2π

The number of times the circumference of a circle is more than the radius of the circle.

If a radian is defined as the angle formed by an arc length of a circle subtended at the center that is equal to its radius, then there are 2π radians, or 2π radii, that fit around the circumference of the circle. In other words, 360° equals 2π radians, or one radian is 180°/π, which is about 57.3°.

MAGA

Short for “Make America Godly Again.” A mantra preached by a group of evangelical pastors, who had brainwashed diehard supporters of Trump, the “anointed one,” by proclaiming that there exists a parallel between Trump and Jesus, who have both come to deliver and save them—they need to stand up for Trump, who had selfishly used religious leaders as pawns and disinformation to incite an insurrection.

Evangelical leaders who risk losing (or have sold) their souls for grasping political power are preaching Trumpism or white supremacy under the flag of Christian nationalism—aren’t their preaching the political slogan MAGA, instead of the Magi, a stumbling block to millions of pre-believers of Christianity?

Not all vaccines are created equal.

When non-Western home-grown—half-baked or partially trialed—vaccines are shunned even by locals, which are often donated or exported at a discounted price to developing countries that can’t afford the “safer” ones produced by the West—the top three countries involved in this vaccine diplomacy game are China, India, and Russia, whose “cheap-and-cheat” vaccines do not exude much confidence among millions of targeted recipients.

Although the Chinese, Indian, or Russian vaccines are offered free of charge to them, millions of people in the developing world refuse to be jabbed, because they know too well that not all vaccines are created equal.

White Terrorist-in-Chief

The latest notorious title conferred on Donald J. Trump for the deadly insurrection at the US Capitol, when his diehard supporters-turned-terrorists stormed the building, and threatened to kill the Vice President and endanger the lives of lawmakers.

Liar-in-Chief, Pinocchio-in-Chief, Divider-in-Chief, Faker-in-Chief, …, Pharisee-in-Chief, Hoaxer-in-Chief, Conspiracist-in-Chief, White Terrorist-in-Chief, it’s hard to imagine another rogue or fake leader collecting so many ignoble titles while in office, except perhaps for Kim Jong Un who has been honored with dozens of laughably flattery titles.

Trumpability

A mélange of bigotry, corruptibility, conspiracy, criminality, cruelty, dishonesty, idolatry, illegality, immorality, infidelity, insecurity, jealousy, religiosity, and treachery that characterize a white racist and supremacist.

Anyone flirting with trumpability isn’t too far from white terrorism, if they don’t get what they want by ethical or legal means.

Fakeful

The opposite of being fact-based. When someone entertains opinions or views that are not true, and deliberately disseminates them to mislead their unquestioning or uncritical audience to push their own agenda.

Rejected Donald J. Trump was such a fakeful character who led tens of millions of his followers to blindly or uncritically put their faith in him, by lying that he’s robbed of an election victory due to rampant fraudulent ballots in states where he lost to his political opponent.
