The real-life story behind the hit movie Hidden Figures doesn't end once the credits roll; for educators, there's now a free curriculum to use in the classroom that shines a light on the pioneering African-American women of NASA's space program.

Published by Journeys in Film, this Hidden Figures curriculum is made up of eight lesson plans aimed primarily at social studies classes, covering topics such as the Cold War, the Civil Rights Movement, and the math of space travel. In addition to fleshing out the social and political climate that Mary Jackson, Katherine Johnson, and Dorothy Vaughan were living in, some courses also focus on the movie itself, with attention paid to the filmmaking techniques used and an analysis of the shooting script.

The curriculum also provides activities revolving around the role of women in STEM, including a breakdown of notable figures, group projects, and information on how students can channel their academic passions into a career. Handouts, quizzes, YouTube links, and related articles are all included in the curriculum to help flesh out the provided material.

Journeys In Film is a nonprofit organization that advocates the use of film as a means of teaching broader lessons in the classroom. The curriculum, which comes in at over 140 pages, can be downloaded for free here. And you can pick up Hidden Figures on 4K Ultra HD, Blu-ray, and DVD today.

History
When Math Discoveries Led to Banned Numbers

The literature world has seen more than its share of controversy. The best stories tend to provoke the strongest reactions—both positive and negative—in readers, which is why so many classic books have been banned at one point or another. But even a more objective field like math isn’t immune to conflict. In its new video, TED-Ed rounds up the numbers that caused such a stir when they were introduced that they were banned in math circles.

One of the earliest examples comes from ancient Greece. A mathematician named Hippasus was having trouble solving certain equations with fractions and whole numbers alone, so he came up with irrational numbers to make these values easier to express. The ruling school of thought at the time dictated that everything in nature could be explained elegantly with the numbers that already existed. Threatened by Hippasus’s new notion, his fellow mathematicians rejected the irrational numbers and had him exiled.

Other numbers have been banned for legal reasons. When Arab traders brought their positional number system, which included zero, to Italy in the Middle Ages, Florence banned it from record-keeping fearing that they would be easier to forge than Roman numerals. The Arabic way of counting also led to the rise of negative numbers, which were regarded with disdain by many experts into the 19th century. For more banned numbers, including some that are prohibited today, check out the full story below.

An Ex-Google Engineer Just Reinvented the Measuring Cup

Recognizing a problem most people didn’t even know they had, former Google and Facebook software engineer Joshua Redstone has made a bold claim for his recent Kickstarter venture: He’s developed a better measuring cup.

According to the Boston Business Journal, Redstone spent four years tinkering with a solution to something that had long annoyed him as an amateur chef: Traditional measuring cups, which are stocky and not very well tapered, don’t do a great job of accurately measuring their own contents. Redstone believes the shape of a cup determines its success, particularly when a cook overfills a liquid or solid by a tiny amount. The smaller the volume, the more the problem is magnified.

Redstone’s cup, Euclid, resolves the issue. According to the Kickstarter page: “With traditional measuring cups, the smaller the amount, the harder it is to measure accurately. The culprit? The shape. Straight sides magnify errors when measuring lower down in the cup. Some have tried to solve this problem with conical measuring cups, but their results fall short of Euclid’s by up to 60 percent. Euclid is the only measuring cup with a mathematically optimal, tapered design for consistent accuracy across amounts.”

Euclid is just about ready to overshoot its $30,000 Kickstarter goal. Backers can pay $24 for the cup now, or wait until it’s available at retail for a slightly higher price to be determined. The cup is scheduled for release in May 2018.
