The Cubing Community Megasurvey 2021 Acknowledgements
THE CUBING COMMUNITY MEGASURVEY 2021 ACKNOWLEDGEMENTS This work follows in the footsteps of the r/Cubers tradition of yearly Megasurveys, of which this is the fifth instalment. For the first time we've been able to integrate the responses and experience of our colleagues from China, whose communities do not always have access to the same online spaces. We're happy to present the results of this survey as a whole, reuniting these two big communities The following people contributed to this project: You guys were awesome, The r/Cubers mods: have been running the survey for the • welcoming and super supportive past 5 years, wrote and managed the bulk of it and proofread this during the whole analysis process! whole monster of a document. Thank you naliuj, gilzu, stewy, greencrossonleft, topppits, g253, pianocube93 and leinadium! It's been a blast discussing with you, Ruimin Yan / CubeRoot : provided great ideas for the • getting your ideas and seeing you recruit survey, helped coordinate between the east and the west, a thousand people in a matter of days! leveraged his online standing and following to gather all respondents across China and re-translated most this document • Justin Yang: translated the survey into mandarin and helped You have no excuse for speaking re-translate answers during the re-combination and cleanup flawless french (on top of all phase your other languages) at your ridiculously young age! About the author of this document: Basilio Noris is an older cuber, who has spent the past 15 years working on understanding and measuring human behaviour. He spends way too much time playing with data and looking for ways in which to present it. -

Syllabus Draft
5 SPEEDCUBING: HISTORY, THEORY, AND PRACTICE Syllabus, Fall 2009 Instructor: Lucas Garron Email: - Class Meeting Time: Undetermined (tentatively, late afternoon/evening, 2 hours) Office Hours: Cube Club Meetings and by appointment COURSE DESCRIPTION Speedcubing is the modern sport revolving around solving the Rubik's Cube quickly. In this course, we will cove the history of the cube and what led to its current status. We will also look at the current cubing community, as well as topics like basic math theory about the cube. Students will learn to solve a cube, and will be introduced to concepts and resources that can help them improve their speedsolving skill. GRADING This course is only offered for one unit, Pass/No Credit. In order to receive a passing grade in the course, each student will be expected to: • Attend and participate in class (no more than two unexcused absences). • Complete the readings/homework, and discuss them in class. • Complete ONE of the following and give a short presentation about it to the class: ◦ A research project on a person associated with the cube. ◦ A short research paper on an aspect of the Cube (approved topic). ◦ Learn a significantly advanced system for the Rubik's cube (will be reviewed for effort). Examples: Blindfolded Solving, Petrus, Heise, Roux, ... ◦ A multimedia/programming project for the Cube. ◦ A self-proposed project that involves specific research or work. Note: Students will learn to solve a Rubik's Cube, but solving a cube is not a requirement for passing the course. Students are also encouraged to attend cube club meetings and participate in the Stanford Fall Competition. -

Chris Hardwick's Rubik's Cube Page 3/11/11 5:56 PM This page is for people who are interested in the Rubik's Cube, and other Rubik's puzzles. I've been interested in the Cube and other puzzles since June of 1998 and I still love doing them. I enjoy speed solving for all my puzzles, especially the Rubik's Cube. If you enjoy the cube or other Rubik-like puzzles then I invite you to browse my site. I hope you enjoy it.

I was then able to solve it in 18.50 seconds while blindfolded. I did not do any moves on the cube during the planning phase.
