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°.

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.

Get the Ⓥalentine’s Day mug.Short for “Stop the Trumpshit.” When thousands of Trumpists of all stripes—conservatives, Republican senators, right-wing and far-right groups, and conspiracists—descended on Washington, DC to protest the results of the 2020 presidential election—unfortunately, their president had zero time for them, who was playing golf while they were protesting for him.
As the world watches pro-Trump events like “Stop the Steal” and “Million MAGA March,” they just want to tell the noisy minority of deluded and disappointed protesters, “Stop the TS” and “Don’t let Trump’s dirty feet walk through your mind.”

Get the Stop the TS mug.When a math teacher decides not to hurt the feelings of their weak students, by insincerely using large numbers and symbols to grade their test paper—for example, a student receiving back their exam paper with a score of (√81)/90 or 4²/100, mistaking it for 81/100 or 42/100.
Some parents object to teachers’ “mathematical sensitivity” or fake feedback, preferring that they’d tell their child the painful truth how poorly they had performed in their math test.

Get the Mathematical Sensitivity mug.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.
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.

If all of earthlings’ talks and tweets about Donald J. Trump’s lies and white lies while he was at the White House were to be made available online, would a coronabyte suffice to storing them?

The answer to “Would Covid-19 booster shots be needed to protect the public against the variants?” is a no-brainer to vaccine producers.
