I was in Melbourne in April 2017 and so I dropped by to have a chat with Feliks Zemdegs: the perpetual Rubik's Cube World Champion. We talk about his recent 4.73 second record-breaking solve, how solving other types of Rubiks puzzles are different (Megaminx, 4×4, 5×5 etc) and how fast he thinks the world records can get. If you want to learn speed cubing: Feliks has a website with tutorial videos! https://cubeskills.com/ Or buy yourself a speed cube. https://mathsgear.co.uk/collections/rubiks-cubes Check out Feliks’s 4.73 second solve sat next to Mats Valk. https://www.youtube.com/watch?v=R07JiT0PlcE He puts videos of his new records up on his channel (including his new 3×3 average record of 5.97 seconds). null His dad also has a channel! https://www.youtube.com/watch?v=1xa_fGG0VxU Here is the video of when I went to a cubing comp. https://www.youtube.com/watch?v=NzfSombRHIM And my interview with Mats Valk. https://www.youtube.com/watch?v=VEsFoinLHrk Current list of Rubik’s World Records: https://www.worldcubeassociation.org/results/regions.php CORRECTIONS: None yet. Let me know if you spot anything (other than records which have since been broken and so the ones mentioned in the video are no longer true). Thanks to my many Patreon supports!
