The son of Paul Christie and Sonya Stagnoli, Ben and his sister Bella are home-schooled students who also take college courses. He'll graduate with an associate's degree from Germanna Community College next spring, at about the same time that he receives his high school diploma. She takes classes at Rappahannock Community College.


Grad student created an amazing Rubik's Cube prototype for the blind

A 1974 invention is getting a very inclusive makeover. Kristen Sharpless had an interesting assignment for her Intro to Vision Rehab Therapy class. The graduate student from the University of Massachusetts was assigned to create an adapted recreational game for someone who is blind. In a flash of inspiration, she created a Rubik's Cube with tactile inputs so people with limited vision could still use it. She posted the prototype on Reddit and immediately received an outpour of positive comments.


Rubik s Cube records broken in 4.59 seconds

Daily Mail

A 23-year-old'professional speedcuber' has set a new world record by completing a Rubik's Cube in just 4.59 seconds. Korean SeungBeom Cho solved the 3D puzzle in his first round at the World Cube Association's ChicaGhosts 2017 event in Chicago, smashing his previous personal best of 6.54 seconds. Footage of Mr Cho's attempt shows him given just a few seconds to examine the cube before starting, completing it just moments later. A series of UK records have been broken by quick-fingered Rubik's Cube solvers at the UK championships held in Stevenage, Hertfordshire on Sunday. Competitors as young as seven tackled the notoriously tricky cubes one-handed, blindfolded and even with their feet in a bid to become the top gamers of the weekend.


This video of a kid solving a Rubik's Cube in 4.5 seconds will give you the purest joy

Mashable

Most of us will go through life mildly pondering a Rubik's Cube every now and then, but a professional speedcuber can solve one in seconds – a record speed of 4.59 seconds, to be exact. In a new video, Korean speedcuber SeungBeom Cho solves a cube so fast that most of the people around him don't even realize what happened. Indeed, their realization takes longer than it took him to solve the cube, but the room erupts with congratulations, applause, and paparazzi-level enthusiasm for Cho's accomplishment.

Cho broke the record using a specific technique (it's posted in the video description but unintelligible if you're not a skilled speedcuber).


[Discussion] Solving a Rubik's Cube using a Simple ConvNet • r/MachineLearning

@machinelearnbot

Plenty of efficient algorithms exist to solve a rubik's cube. I was curious to find out if a neural net could learn how to solve a cube in the most "efficient" way, by solving the cube in less than 20 moves, i.e god's number. I used a 2 layer neural net: 1 convnet layer and 1 feedforward layer. For the training set, I generated games at random during training for games of 10 moves or less from solved with the corresponding solutions as label.

"Consumers who expect to receive plaintiff's Rubik's Cube puzzle, for which plaintiff has developed a national and international reputation, will be disappointed when using defendants' imitation," which causes "irreparable harm" to Rubik's Brand's reputation and goodwill, the complaint said.


It's not you – solving a Rubik's cube quickly is officially hard

New Scientist

A recent study shows that the question of whether a scrambled Rubik's cube of any size can be solved in a given number of moves is what's called NP-complete – that's maths lingo for a problem even mathematicians find hard to solve. To prove that the problem is NP-complete, Massachusetts Institute of Technology researchers Erik Demaine, Sarah Eisenstat, and Mikhail Rudoy showed that figuring out how to solve a Rubik's cube with any number of squares on a side in the smallest number of moves will also give you a solution to another problem known to be NP-complete: the Hamiltonian path problem. On the other hand, problems that have algorithms that run their course in a more reasonable amount of time based on the number of inputs are called P. Researchers are still unsure whether algorithms exist that can solve NP-complete problems faster. "We know an algorithm to solve all cubes in a reasonable amount of time," Demaine says.


Check out the world's biggest freestanding Rubik's cube

Popular Science

Steve Miller Band's The Joker was on the FM dial and Mohammed Ali had trounced George Forman to regain his heavyweight title in the much hyped (if questionably named) Rumble in the Jungle. Inflation had reached double digit highs, gasoline was in short supply, President Richard Nixon stepped down in the wake of the Watergate Scandal, and a 29-year-old Hungarian architect by the name of Erno Rubik had finally figured out how he could take a block made of smaller blocks and get the smaller cubes to move without causing the whole structure to fall apart. And thus, the Rubik's cube, which would eventually go on to delight and torment millions, was born. Ostensible a toy, Rubik's cube has since been the subject of everything from high school math class experiments to serious research in computer science. This week, students at the University of Michigan did Rubik one better, building the world's largest freestanding cube and overcoming a design challenge not too dissimilar from Rubik's original quandry--how to get the cubes to spin.

Although an expert Rubik's player can solve the puzzle in seconds, the nature of this particular cube means that even the best player will need a lot more time to finish, according to cube co-developer Ryan Kuhn.
