"Mysterious radio signal from space"

“Mysterious radio signal from space is repeating every 16 days Ashley Strickland-Profile-Image By Ashley Strickland, CNN Updated 5:19 PM ET, Tue February 11, 2020”

Does NASA know this?

I checked and NASA has nothing about a mysterious radio signal. Do you think someone should tell them?

No evidence

“The president retweeted assertions that Romney “stabbed Trump in the back” by joining Democrats in attempts to overturn the 2016 election, and that the Utah senator was connected to unsubstantiated claims that Hunter Biden, the son of former Vice President Joe Biden, was corruptly involved with the Burisma Holdings energy company in Ukraine.”Feb. 9, 2020

“…Hunter Biden, the son of former Vice President Joe Biden, was corruptly involved with the Burisma Holdings energy company in Ukraine.”

U.S.A.

I’m reading New Yorker Melville’s  1851 Moby-Dick about the adventures of his narrator Ishmael and cannibal bedfellow Queequeg; I’ve read some of the poems in Leaves of Grass published in 1855. I have a U.S. postage stamp commemorating the Polish General Casmir Polaski who fought in the revolutionary war with George Washington and co-founded the U.S cavalry with Hungarian Michael Kovats de Fabriczy who died in that war and is buried in Charleston, South Carolina (Field of Battle).

Today the United States is depicted as a racist anti immigrant nation because of its rules for citizenship. We hear nothing of Republican Lincoln and Democrat Wallace and no public effort to explain the significance of two European aristocrats Polaski and Kovats de Fabriczy fighting the revolutionary war and founding an order of the early U.S. military, nor the surprisingly respectful friendship of Christian Ishmael and Pagan  Queequeg.

UK’s SUN versus NASA

Here’s what Pettit of UK’s Sun says

“INCOMING

Mystery object approaching us from interstellar space could be ALIEN spacecraft, top scientist admits”

And these are NASA’s up coming events:

nothing about that “Mystery object” that Mr. Pettit thinks “could be ALIEN spacecraft”.

Inquiry and Math

The province of Ontario’s Conservative government concerned about Ontario students’ declining math scores will require new elementary teachers to score 70% on a math test. The Toronto Star, critical of the Conservative government’s apparent intention to emphasize rote learning in reforming the teaching of elementary school math, says in its August 30, 2019 editorial, “The EQAO results show (s) the province may be on the wrong track with its plan to ditch inquiry-based math for a back-to basics curriculum.”

But neither the “back-to-basics”, nor “inquiry-based” verbiage used in politicised rhetoric about education have any relevance for teaching and learning math. Ironically commonly held notions about research and evidence have come to inhibit the “inquiry” of rational unencumbered thinking in all fields, especially journalism where news articles of identical content appear to cease on about the same date, as if all were written by the same media organization.

Perhaps the champions of “inquiry-based” math have Euclid, Proclus, Leibnitz, Newton, Dedekind, Peano, or even Lorenz and Einstein in mind as inquirers who had the desire and energy to master then challenge systems established by their predecessors.

Mathematics is no longer just arithmetic: adding, subtracting, multiplying and dividing things like jelly beans, sticks and stones that everyone can see and count. But if these simplistic numeric operations aren’t mastered the algebraic symbols that have come to stand in the place of numerals may mystify both students and teachers unable to understand why math seems difficult. Today the subject once known as arithmetic has reached another level of abstraction; algebraic variables have become place holders in a math category called calculus together with its new set of symbols.

Learning arithmetic, algebra, functions, and finally calculus constitute learning 4 languages 3 of which require facility in a preceding language.

Algebra needs arithmetic; functions algebra; and calculus functions.
