Covid-🦃

When desperately needed foreign workers trained to slaughter and process turkeys reared for Christmas are not allowed in the country unless they serve their 14-day quarantine on arrival, whose absence would affect producers with low supply and consumers with high price.

Thanks to Covid-🦃, a lucky percentage of the nine million turkeys in the UK would have their lives spared during this 2020 Christmas period.

Political Mask

When the wearing of a face mask has turned into a divisive political issue in a number of countries that protect their citizens’ individual rights, whose selfish behaviors in donning zero masks in public in the midst of a pandemic crisis endanger the health of the majority.

Alt-right politicians are pushing their political mask agenda, by pretending to address the anti-social demands of a noisy minority to win their votes.

Voodoo Math

Also known as “Haiti Math”—voodoo is an unofficial religion practiced in Haiti. Math word problems that use zombies or monsters as their characters to teach dark problem solving.

An example of a grade two voodoo math question is: “The line graph shows the weekly number of zombies that were caught by the police during the six-week nationwide lockdown. Use the diagram to answer the following questions.

a) How many more zombies were caught in April than in May?
b) If the zombies were able to bite a victim before they were caught, what is the least number of zombie bites that took place during the entire lockdown?”

Pythagorean Diet

When math geeks tell others that they eat or use zero animal products like honey, seafood, egg and diary, fish, and meat—named after Pythagoras, the Greek vegetarian mathematician-turned-numerologist.

Alt-right Trumpists and QAnonists never fail to remind each other that Adolf Hitler adhered strictly to a Pythagorean diet during his years-old tyrannical rule, unlike their Insurrectionist-in-Chief boss, who occasionally craves for junk food.

Pi Is Sovereign

When mathematics’s most famous constant π transcends different math topics and disciplines, permeates both art and science, and lays hidden in philosophy and religion, often popping up in the least expected places in nature—the symbol π is a global icon that resonates positively or negatively with peoples of all ages and backgrounds.

Pi is sovereign among dozens of mathematical constants, but God is Sovereign among thousands of gods and goddesses, or deities and idols.

What you need if you want to represent nothing with nothing.

Pi and Friends

When the irrational number π appears to be particularly attracted to numerical buddies like e, i, and 𝜙 whenever they are indulged in some extra-mathematical activities together, as revealed by their intimate liaisons.

Don’t the following numerical relationships prove that pi and friends have an affinity for one another?
π ≈ 6/5 𝜙²
π ≈ (9 – e)
iⁱ = e^(-π/2)
e^(iπ) + 1 = 0

(- )! = √π
eⁱˣ = cos x + i sin x
