MIT robot solves Rubik's Cube in world record time: 0.38 seconds
This MIT robot solves it faster than any human ever could. It's a world record.
- A robot developed by MIT students Ben Katz and Jared Di Carlo has set the world record for solving the Rubik's Cube.
- The fastest human record is held by Australian Feliks Zemdegs, who solved it in 4.22 seconds in 2018.
- The original-size Rubik's Cube (3x3x3) has 43 quintillion possible combinations – and one solution.
There's a special place in our hearts for the Rubik's Cube. Pop culture icon and shorthand for intelligence, many dabblers have played around with this ingenious toy, and throughout the years there has been a number of competitions, challenges and variations for solving it.
The popularity of the Rubik's Cube can be attributed to the simplicity of its design combined with the mind-boggling complexity of the puzzle; there is one solution out of 43 quintillion possible combinations.
It was only a matter of time before the engineers and roboticists got to tinkering with it. Back in 2016, a robot set a new record for solving the cube in 0.637 seconds. But that wasn't fast enough for some. More recently, two MIT students, Ben Katz, a mechanical engineering graduate student, and Jared Di Carlo, a third-year electrical engineering and computer science student, thought they could one-up that.
"We watched the videos of the previous robots, and we noticed that the motors were not the fastest that could be used... We thought we could do better with improved motors and controls."
They set up a motor actuating within each face of the Rubik's cube controlled by electronics for control. With the assistance of webcams pointed at the cube, custom software determines the initial state of each face. Then, utilizing pre-existing software to solve the Rubik's Cube, the robot was guided to solve the puzzle.
The result? Their robot solved the Rubik's Cube in 0.38 seconds. It's safe to say that no human is physically capable of beating this speed. And we can add another achievement to the list of robots outperforming humans.
The human who has the fastest world record for hand-solving is Feliks Zemdegs. He was able to solve a Rubik's Cube in 4.22 seconds. Which is also nothing to sneeze at. The skills and talents robots are displacing are vast and varied to say the least. Not to mention surprising.
Now, watch the video a few more times and let your inadequate human hands fathom that speed.

Construction of the $500 billion dollar tech city-state of the future is moving ahead.
- The futuristic megacity Neom is being built in Saudi Arabia.
- The city will be fully automated, leading in health, education and quality of life.
- It will feature an artificial moon, cloud seeding, robotic gladiators and flying taxis.
The Red Sea area where Neom will be built:

Coronavirus layoffs are a glimpse into our automated future. We need to build better education opportunities now so Americans can find work in the economy of tomorrow.
- Outplacement is an underperforming $5 billion dollar industry. A new non-profit coalition by SkillUp intends to disrupt it.
- More and more Americans will be laid off in years to come due to automation. Those people need to reorient their career paths and reskill in a way that protects their long-term livelihood.
- SkillUp brings together technology and service providers, education and training providers, hiring employers, worker outreach, and philanthropies to help people land in-demand jobs in high-growth industries.

Do we really know what we want in a romantic partner? If so, do our desires actually mean we match up with people who suit them?
- Two separate scientific studies suggest that our "ideals" don't really match what we look for in a romantic partner.
- Results of studies like these can change the way we date, especially in the online world.
- "You say you want these three attributes and you like the people who possess these attributes. But the story doesn't end there," says Paul Eastwick, co-author of the study and professor in the UC Davis Department of Psychology.
Do we really know what we want in love or are we just guessing?<span style="display:block;position:relative;padding-top:56.25%;" class="rm-shortcode" data-rm-shortcode-id="204859156383d358652fda6f7eadda0f"><iframe type="lazy-iframe" data-runner-src="https://www.youtube.com/embed/vQgfx2iYlso?rel=0" width="100%" height="auto" frameborder="0" scrolling="no" style="position:absolute;top:0;left:0;width:100%;height:100%;"></iframe></span><p>More than 700 participants selected their top three qualities in a romantic partner (things like funny, attractive, inquisitive, kind, etc). They then reported their romantic desire for a series of people they knew personally. Some were blind date partners, others were romantic partners and some were simply platonic friends.</p><p>While participants did experience more romantic desire to the extent that these personal connections of theirs (people they knew) had the qualities they listed, there was more to the study. </p><p>Paul Eastwick, co-author and professor in the UC Davis Department of Psychology <a href="https://medicalxpress.com/news/2020-07-romantic-partner-random-stranger.html" target="_blank">explains</a>: "You say you want these three attributes and you like the people who possess these attributes. But the story doesn't end there." </p><p>The participants also considered the extent to which their personal acquaintances possessed three attributes nominated by some other random person in the study. For example, if Kris listed "down-to-earth", intelligent and thoughtful as her own top three attributes, Vanessa also experienced more desire for people with those specific traits. </p>

What we claim to want and what we look for may be two separate things...
Image by GoodStudio on Shutterstock<p>So the question became: are we really listing what we want in an ideal partner or are we just listing vague qualities that people typically consider as positive?</p><p>"So in the end, we want partners who have positive qualities," Sparks explained, "but the qualities you specifically list do not actually have special predictive power for you." </p><p>In other words, the idea that we find certain things attractive in a person does not mean we actively seek out people who have those qualities, despite saying it's what we want in a love interest. The authors of this study suggest these findings could have implications for the way we approach online dating in the digital age. </p><p>This isn't the first study of its kind to suggest that what we find in love isn't really what we were looking for. The evidence suggests that we really are consistent in the abstract of it all: when asked to evaluate what you want on paper, you are more likely to suggest overall attractiveness in accordance with what you've stated are important ideals to you. But real life isn't so similar. </p><p>According to <a href="https://www.psychologytoday.com/us/blog/meet-catch-and-keep/201506/when-it-comes-love-do-you-really-know-what-you-want" target="_blank">Psychology Today,</a> who covered a 2015 study with similar results, initial face-to-face encounters have very little effect on our romantic desire. "When we initially meet someone, our level of romantic interest in the person is independent of our standards."</p><p>While you might have no immediate interest in John, he may fit your criteria of being kind, loyal, and intelligent. Similarly, someone may be attracted to Elaine even though she doesn't have any of the qualities they originally said were important to them. </p><p><strong>What does this all mean? </strong></p><p>The authors of both the 2015 and 2020 studies say the same thing: give someone a chance before writing them off as a poor match. If your initial attraction is independent of the standards you've set out, the qualities which you've listed as important to you, the first time you meet someone may not give you enough information to make an informed decision.</p><p>"It's really easy to spend time hunting around online for someone who seems to match your ideals," said Sparks, "But our research suggests an alternative approach: Don't be too picky ahead of time about whether a partner matches your ideals on paper. Or, even better, let your friends pick your dates for you." </p>
