They touch on history, etymology, and puzzles, and make connections to everything from art and architecture to science and nature. The judging panel loved the wide range of Apoorva’s blog posts. Combining clear explanations with an appealing layout and well-chosen graphics, Gems in STEM is itself a gem. The judges were very impressed with Apoorva’s joyful, elegantly written blog posts on a wide range of math topics, from the liar’s paradox and partitions to tessellations and fractals. For both my own fun and for readers, I weave in pop culture, pick-up lines, and over-the-top stories to let people into the fantastical world of math, and to show them that anyone can enjoy anything.” I assume no more than basic math knowledge and include fun tidbits for learners of all experience levels. ![]() She sees her blog as “a place to learn about math topics in an accessible, light-hearted manner. She writes a blog called “Gems in STEM” and frequently posts the essays on Cantor’s Paradise, the #1 math site on. The judges felt that their own words were inadequate to summarize Julia’s achievement in writing “Math Person.” Let us simply say, read her poem and experience it for yourself.Īpoorva Panidapu is a 16-year-old mathematics student, artist, and advocate for youth and gender minorities in STEAM. I want to go back into that auditorium and finish the exam and talk about it all night. I don’t want to be patted on the shoulder and misunderstood. Not seeing what it was all for, wishing – but never working up the guts to push – for more. I’m someone who sat through the slow-drip of middle school math, bored and daydreaming, Mom offers to stop by Panera as a treat for all the painful math that I’ve just endured. “Math Person” conveys – in ways both beautiful and haunting – the isolation Julia felt as one of the only girls in the American Math Competition 10th grade and, more profoundly, the intellectual isolation she still feels every day as someone who loves math deeply yet lacks a friend with whom to share it. Julia Schanan’s entry for the Strogatz Prize was a free-verse poem titled “Math Person.” The judges were moved by the poem’s artistry and emotional power, its depth and raw honesty, its brilliant use of language, and its eye for the unexpected but telling detail. Here are all of the positions superimposed, once again thanks to the GIMP: (Note the gaps between the diagonals and uprights are as designed, see the construction sketch above.) By now we’ve created the letters “M,” “A,” and “T” for you with linkages, so I will leave you with a reader challenge: create a linkage which lays out a letter “H”! Send pictures of your creation to article first appeared on Make: Online, August 27, 2012. You have to ease it one direction to get some of the strokes of the M, and then go back and ease it the other way to get the remainder. Note that there is a slight trick, in that the link above is at what’s called a “dead point” - the joint between C and D can bend either up or down for B to rotate. In any case, your linkage should look like this: To use: Fix A vertically (as shown above), and rotate B to move the 25-bar successively into the four positions of the strokes of an “M”. Its endpoints do not remain on any circles but those of bar C do, and the 25-bar is in a fixed relationship to bar C. This 25-bar will take on the positions of the four strokes of a capital M. Ingredients: A 55-bar (A), 60-bar (B), 18-bar (C), and 15-bar (D) a 25-bar and four linkers.ĭirections: Link A to B to C to D, and then affix the 25-bar at right angles to C, about two-thirds of the way from B to D. This produces our next recipe: 4-Bar M Linkages I’ve applied that (somewhat involved) construction to four positions for a bar which lay out the strokes of a letter “M”, as seen in this image and Geogebra worksheet. Moreover, this theory gives a geometric construction to find the centers of the respective circles, which is all you need to find the linkage. ![]() What Burmester realized is that although the endpoints of the floating bar might not lie on a circle, there might be (and in fact are) points in fixed relationship to the floating bar which do lie on a single circle for all positions of the floating bar. So we must be stuck, right? Not quite, thanks to Burmester Theory. And we know that there are four points through which it is impossible to draw a circle, such as the three corners of an equilateral triangle and its center. What about four positions? As you may recall, each endpoint of the floating bar always lies on a circle defined by the fixed bar and one of the bars linked to it. Last time, we saw that a four-bar linkage can cause the floating bar to take on any two or three desired positions. See the introductory column in this series for the MoMath Linkage Kit, an introduction, and general instructions. We’re still putting four-bar linkages through their paces.
