If only you’d sent your child to “a “no excuses” charter school.” Then they “would have received a solid education” and the story would be about “the effectiveness and impact coherent curriculum, strict discipline, effective teacher training, and high expectations have on student success…”

If anybody is curious- it's 95% student centric. Based entirely on the idea of a central angle (in degrees) creating an arc length on the circumference of a unit circle (i later break it to them that these are radians), then adding in the coordinate of that point drive.google.com/drive/folder...

A student is more likely to complete homework if:
Separate work space (desk)
Quiet
Support available in evening Support is college educated
Support is fluent in English
Computer and internet
Protected homework time

Carl Sagan worked for a year with a diverse team to assemble the Golden Record that accompanied Voyager 1 & 2, both of which have now left the solar system. But how would an alien civilization play a golden record & how could a phonograph record contain sound AND image data? Let's talk about it.
Carl Sagan shows the *Pioneer plaque*, not the Golden Record design.  This was decried as "smut in space!" by hand-wringing weirdos, which is the reason the Voyager probes don't show naked humans on it.

Whoa my book just got a glowing review in a math journal, and the best part is the reviewer’s main complaint: she kept wanting more math, then remembered it isn’t written for mathematicians. Correct! It’s for EVERYONE—no formulas, just stories of data fighting injustice. I hope you will read it.
Screenshot of a book review from The American Mathematical Monthly. Header: "Unlocking Justice: The Power of Data to Confront Inequity and Create Change. By Chad M. Topaz, Princeton University Press, 2026. 232 pp., ISBN 978-0691276151, $27.95. Reviewed by Kimberly Spayd." Section 1 is titled "YOUR INVITATION TO BE A MATH ACTIVIST." Spayd writes that the writing and publishing of Unlocking Justice is a political act in today's world: a proud invitation to work towards justice and equity in the criminal justice system using math and statistics, made accessible for a wide audience. She says it would be irresponsible and disingenuous to ignore the advocacy and resistance the book boldly encourages; instead she wants to amplify Topaz's activism and echo his invitation to readers to join the fight. To the question "why do they have to make math political?" she responds that math has been political far longer than Topaz or she have been around: the discipline's politics have promoted certain ideas and people while demoting and minoritizing others. Examples: infinite series, discovered by Madhava and Nilakantha three centuries before Newton and Leibniz but widely attributed to the western greats, and regression, developed by Galton for his still-reverberating eugenics agenda. On the other end of the spectrum, Topaz highlights data analysis and visualizations by Ida B. Wells and W.E.B. Du Bois that raised awareness of racial violence and countered racial stereotypes. Humans do math and bring their identities to their work; nearly everything is political now, including books, data, and knowledge. She argues that becoming a math activist is not accepting the slanderous accusation that higher education is liberal indoctrination; rather, it is academics' professional responsibility to enter political spheres and pursue answers with a critical lens, guiding students to draw their own conclusions—which, she concludes, is what Topaz does for readers of Unlocking Justice.
