Ⓥalentine’s Day

When only vaccinated couples or lovers are allowed to dine at restaurants on singles’ “most dreaded day of the year” if they show proof of inoculation at the entrance, or had previously emailed a copy of their certificate of vaccination while making a booking.
On this Ⓥalentine’s Day, guesstimate how many unvaccinated couples worldwide were turned away because they posed a health hazard to both restaurant owners and staff and the diners.

Pimp Up Pi

Make the number π look sexier by expressing it equivalently or approximately in an expression of numbers or/and constants—for example, π = 1 – 1/3 + 1/5 – 1/7 + 1/9 – 1/11 + ⋯, π ≈ √2 + √3, π⁴ + π⁵ ≈ e⁶, and π rad = 180°.
To get othersattention to its numerical beauty, mathematicians never fail to pimp up pi.

Covid-19 Booster Shots

When pharmaceutical companies wish to administer them at least twice a year, which means that they want their vaccines to start losing their effectiveness after every six months, so that they could generate as much profit as possible—more shots, more sales.
The answer to “Would Covid-19 booster shots be needed to protect the public against the variants?” is a no-brainer to vaccine producers.

Space

What you need if you want to represent nothing with nothing.
What’s the difference between nothing and zero? Is one the empty space and the other one a numeral?

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

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.

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.
