Math Fan Content Lessons Tasks Math Club Projects Math @ Home Math Magic Games & Puzzles Math & Art Cylindrical Mirror and Anamorphic Art << Math & Art The distorted (anamorphic) images grab everyone's attention. In the cylindrical mirror example, hidden pictures are drawn on a POLAR GRID and they only come to life when viewed through a cylindrical mirror. ​ The original art requires a mirroring paper, but nowadays, unwrinkled aluminum foil can be used as well (But because the images are fuzzier, the observations may not be as clear.) A soda can or any cylindrical object that you can cover with aluminum foil is ok. After creating the cylindrical mirror, you may either color an already distorted image or print the polar grid below and create your own anamorphic art. ​ Images are taken from the book " The Magic Mirror: An Antique Optical Toy " How it works - MATH CONNECTION Phaeno Science Center, Wolfsburg /Germany Exploratorium, San Francisco /United States Making anamorphic drawings involves mechanically distorting an image by transferring the image from the square grid (the original image) onto a polar grid (distorted grid). ​ It is basically done by transforming each cartesian coordinate to the corresponding polar coordinate. ​ You can use any polar grid by printing to make your own drawings. For this example, after you complete your image on the polar grid, place your cylindrical mirror on the circle and look into the mirror to see the image restored. One might wonder what happens if we use a conical mirror instead of a cylindrical one! With a conical mirror, the image is spread out in a circular region all around the mirror creating a perfectly circular image. Did you hear about the mirror pillar? The Mirror Pillar is a giant 2m high cylindrical mirror, which reflects and distorts images from the ground around it to create beautiful anamorphic artworks. It provides a chance to interact with anamorphic images by drawing part of one, and discover the mathematics and geometry behind projected and distorted images. The Mirror Pillar is a math outreach project by mathematicians Matt Parker and Katie Steckles. ​ They also have an image converter where you can upload your original image and it converts to the distorted image on the polar grid. ​ Do not forget to check out the Mirror Pillar activities.

You all are the best. Here are just two of my favorites. By a channel STEM cell: https://youtu.be/ils7GZqp_iE By Doga Kurkcuoglu: http://bilimneguzellan.net/bouncing-cubes-and-%CF%80-3blue1brown/ And here's a lovely interactive built by GitHub user prajwalsouza after watching this video: https://prajwalsouza.github.io/Experiments/Colliding-Blocks.html NY Times blog post about this problem: https://wordplay.blogs.nytimes.com/2014/03/10/pi/ The original paper by Gregory Galperin: https://www.maths.tcd.ie/~lebed/Galperin.%20Playing%20pool%20with%20pi.pdf For anyone curious about if the tan(x) ≈ x approximation, being off by only a cubic error term, is actually close enough not to affect the final count, take a look at sections 9 and 10 of Galperin's paper. In short, it could break if there were some point where among the first 2N digits of pi, the last N of them were all 9's. This seems exceedingly unlikely, but it quite hard to disprove. Although I found the approach shown in this video independently, after the fact I found that Gary Antonick, who wrote the Numberplay blog referenced above, was the first to solve it this way. In some ways, I think this is the most natural approach one might take given the problem statement, as corroborated by the fact that many solutions people sent my way in this last week had this flavor. The Galperin solution you will see in the next video, though, involves a wonderfully creative perspective.

Two ways to support Mathologer Mathologer Patreon: https://www.patreon.com/mathologer Mathologer PayPal: paypal.me/mathologer (see the Patreon page for details) This video is my best shot at animating and explaining my favourite proof that pi is irrational. It is due to the Swiss mathematician Johann Lambert who published it over 250 years ago. The original write-up by Lambert is 58 pages long and definitely not for the faint of heart (http://www.kuttaka.org/~JHL/L1768b.pdf). On the other hand, among all the proofs of the irrationality of pi, Lambert's proof is probably the most "natural" one, the one that's easiest to motivate and explain, and one that's ideally suited for the sort of animations that I do. Anyway it's been an absolute killer to put this video together and overall this is probably the most ambitious topic I've tackled so far. I really hope that a lot of you will get something out of it. If you do please let me know :) Also, as usual, please consider contributing subtitles in your native language (English and Russian are under control, but everything else goes). One of the best short versions of Lambert's proof is contained in the book Autour du nombre pi by Jean-Pierre Lafon and Pierre Eymard. In particular, in it the authors calculate an explicit formula for the n-th partial fraction of Lambert's tan x formula; here is a scan with some highlighting by me: http://www.qedcat.com/misc/chopped.png Have a close look and you'll see that as n goes to infinity all the highlighted terms approach 1. What's left are the Maclaurin series for sin x on top and that for cos x at the bottom and this then goes a long way towards showing that those partial fractions really tend to tan x. There is a good summary of other proofs for the irrationality of pi on this wiki page: https://en.wikipedia.org/wiki/Proof_that_π_is_irrational Today's main t-shirt I got from from Zazzle: https://www.zazzle.com.au/25_dec_31_oct_t_shirt-235809979886007646 (there are lots of places that sell "HO cubed" t-shirts) lf you liked this video maybe also consider checking out some of my other videos on irrational and transcendental numbers and on continued fractions and other infinite expressions. The video on continued fractions that I refer to in this video is my video on the most irrational number: https://youtu.be/CaasbfdJdJg Special thanks to my friend Marty Ross for lots of feedback on the slideshow and some good-humoured heckling while we were recording the video.

So the real focus is the flexibility of the class design. Versatile seating options, mobile furniture, and welcoming classroom displays are all coming together to allow for independent, partner, group, and collaborative learning. ​ According to Cheryn et al. (2014) “… scientific studies reveal the unexpected importance of a classroom’s symbolic features, such as objects and wall décor, in influencing student learning and achievement in that environment. Symbols inform students whether they are valued learners and belong within the classroom, with far-reaching consequences for students’ educational choices and achievement.” ​ Here are some tips for a creative classroom design; ​ ​ Choose furniture that can be easily moved - classroom spaces should be FLEXIBLE, rather than static Designate different areas of the room to be used for varied learning activities Decorate with the students’ artwork, poetry, or projects. This helps them to find their place in the class community and to feel ownership over the space. ​ ​ Two websites to try different seating arrangements for your classroom; Classroom Architect and Class Set-up Tool ​ Welcome Banners Ready-to-print Welcome Banners with different fonts. ​ docx. pdf. Resources Mathematical Letters Mathonyms is a webpage that re-writes your entry using mathematical letters. Desmos Alphabet Letter Graphs by Desmos Polypad Tangram Letters Letters and Digits made up of tangram pieces on Polypad Math Clocks And here is another option; A model clock by Leonardo Da Vinci. There are many different math clocks around that you can add to your wıshlist or purchase. ​ Buying an empty clock and creating the clock as a class project can be another option. You can find the lesson plan here . Math Calendar You can create a math calender as a long term project with students or buy one that provides a math challenge for every day of the year. Doors to Welcome Students You can start giving clues about the theme of your classroom with an inspiring door design. I chose the Movie " Matrix " as a theme of my classroom, whereas another math teacher who is also a famous travel blogger (IG: @nilyesiliyollar) designed her class door with a world map shows the places of the math museums all around the world. Matrix Theme You can use movie posters to decorate the class doors. World Map Use a world map on the class door to promote the math / science museums or the birth places of famous mathematicians. Pi Number Listing the digits of the iconic Pi number on the math class door. Math Cartoons Math memes and cartoons are very popular among students, so why not use them as door decor! ​ Book Cover Book Covers can be math class doors as well as the Language Class Doors. Word Door An interactive word-door can replace word walls for math classes. ​ ​ Classroom Posters and Manipulatives Here are the pages you can find more ideas to create a welcoming, motivating and inspiring classroom.

Math Fan Content Lessons Tasks Math Club Projects Math @ Home Math Magic Games & Puzzles Math & Art STAR WARS MATH Light Saber Duel with Desmos - Graphing ​ Here is a sample file you can use to create a lightsaber dual on Desmos. I have added PNG images of lightsabers and connected them to the trigonometric functions. You may ask students to write the functions they like to create a fight scene. You may also remind them that it is better to increase the number of intersection points between the graphs for a better duel. Then, you may discuss the properties of the graphs they choose. ​ Star Wars Battleship Game with Polypad - Ordered Pairs ​ Dark Side Polypad vs Light Side Polypad The rules are almost the same as the original Battleship game. Group students in pairs. One side chooses to be the dark side, where as the other is the light side. The Dark Side player needs to set the dark mode ON from the personal settings on the upper right corner. ​ Instructions Arrange your ships on the Grid. (Ships cannot overlap, cannot be re-sized) Light Side has 4 ships; 4x4 Millenium Falcon (Your opponent has to guess all 16 points correctly to destroy the ship) 3x3 X-Wing (Your opponent has to guess all 9 points correctly to destroy the ship) 3x3 Starfighter (Your opponent has to guess all 9 points correctly to destroy the ship) 3x4 Ghost (Your opponent has to guess all 12 points correctly to destroy the ship) Dark Side has 4 ships as well; 4x4 Death Star (Your opponent has to guess all 16 points correctly to destroy the ship) 3x3 Emperor's Shuttle (Your opponent has to guess all 9 points correctly to destroy the ship) 3x4 Star Destroyer(Your opponent has to guess all 12 points correctly to destroy the ship) 3x3 Tie Fighter (Your opponent has to guess all 9 points correctly to destroy the ship) Take turns calling "shots" at the other player's ships to destroy your opponent’s fleet. Each shot will be announced with an ordered pair. For example (3,5) The opponent announces whether it is a hit or miss. If it is a "hit," the player who got hit colors that point red on the ship. Do not forget to record your shots on the tracking grid. When all the points of a ship have been hit (turned red), the ship's owner announces the name of the lost ship. For example, here, the Tie Fighter of the Dark Side has fallen. Destroy the entire fleet of your opponent to win the game. May the FORCE be with you! Paper Circuits Activity by Makerspace ​ This fun STEAM activity has many different options like creating Christmas tree lights and etc. In the Lightsaber version, you need to download the 2-page paper circuit template and print both-sided. The extra materials are Conductive copper tape Transparent tape Coin cell battery -3v LED LilyPad button board Straw Scissors You may also purchase the paper circuit kit from the Makerspace website and follow the instructions. ​ Darth Vader vs Yoda - Symmetry I recently found this little symmetry magic box on Amazon , which can easily be turned into a STEAM activity/project. The materials are; a cardboard box, green and black playdough, and a small double-sided mirror which has the sidelengths ; one side has the same as the box the other has a sidelength equal to the face diagonal of the box. You may discuss the plane symmetries of a cube and the properties of reflection using this activity. Using double-sided mirrors is a great part of many illusions. You may also ask students to create their own magic tricks using double-sided mirrors.​ ​ ​ Check out these great resources abot Star Wars themed STEAM activities NASA Land a Spacecraft on Target Activity CODE.ORG Building a Galaxy With Code Activity STAR WARS Motivational Posters Parallax Angle and Parsecs You may also use Star Wars to talk about the concept like indirect measurement using Trigonometry, 'Parallax angle '. And units used in astronomy like astronomical unit (AU) light-years, parsecs. Here is a mini- activity about the parsecs and the parallax angle usage in Astronomy. Congruency and Similarity with Stormtroopers The army of Stormtroopers can also be used to explore the concepts of Congruency and Similarity. Here is an iBook you can download free and open in your iOS or MAC devices. Free Star Wars Stickers - PDF
