Stop the Steal

What math authors want to tell their local and foreign publishers in Singapore to cease using their content sans their permission in their sample chapters they submit to tender local and foreign projects; to pay them their due royalty when they sell their copyrights at book fairs; and not to rob them, by unscrupulously replacing their names with foreign ones when their textbooks are tailor-made for developing markets.

Singapore will continue to be a first-class economy with a third-class educational publishing industry as long as its unethical publishers pay lip service to stop the steal, with a number of morally corrupt and inept people occupying key positions still around today.

Corona Calculus

The use of differentiation and integration symbols to hypothesize the infection and mortality rates of change in many parts of the developed world. For example, which of the following Covid-19 hypotheses are worth investigating further?

Wuhan: ∫🦠₁₉ dx = 🦇 + c
White House: ∫🦠₁₉ dx = 🇨🇳🧫🧪+ c

Singapore: d/dx (🦠₁₉) = 😷x + 💀y
US: d/dx (🤥₄₅ + 🦠₁₉) = 😷ˣ + 💀ʸ

Corona calculus helps us to differentiate between facts and falsehoods about the coronavirus, while we integrate the latest effective preventive measures adopted by countries with low infections and deaths to control the pandemic crisis.

🇸🇬 🔢

Singapore Math in two characters. A mélange of the best math curriculums from the East and the West, which is arguably the catalyst for Singapore students to repeatedly rank top in international comparative studies like PISA and TIMSS.

In emoji, 🇸🇬 🔢 = (🇺🇸 + 🇬🇧 + 🇨🇳 + 🇰🇷 + 🇷🇺 + 🇮🇱) × 🔢—why should Singapore reinvent the wheel when it can steal the best mathematical ideas from others?

Origask

Short for “origami mask.” The art of making a face mask using origami paper (and string or rubber band if you don’t mind wearing it to make some kind of political, religious, or social statement to attract attention).

How long does it take, or how many folding steps are needed, to make an origask?

Trumpvirus’s Infectivity

The rate at which Donald J. Trump’s conspiracies and lies about fraudulent ballots brainwashes his oft-gullible hardcore supporters to donate to the post-election fund to "protect the results and keep fighting even after Election Day.”

Trumpvirus’s infectivity incited both Trumpists and QAnonists to contribute tens of millions of dollars, which could be used to settle part of the president’s bigly debt and to finance his own political rallies, especially if he’s running again in 2024 (assuming that he’s not behind bars by then).

Pi on Earth

When the symbol π is stone-carved against a circular background of a different color on the ground.

If the value of π in heaven is arguably 3, which is computed based on two biblical verses (1 Kings 7:23 and 2 Chronicles 4:2), what is the value of pi on earth then?

Christ and Corona

When Jesus Christ, the King of kings, allows Satan, the “father of lies,” to call on Ms. Corona, the “queen of the viruses,” to roam the earth (and possibly hell, too) to infect millions of people, and to prematurely end the lives of hundreds of thousands of people, young and old, rich and poor, or smart and dumb.

Although God has the power to stop the pandemic any time, however, it looks like He decided not to get involved in any conversation between Christ and Corona, or between Corona and Lucifer, for whatever spiritual reasons unknown to the earthlings.
