A Brief History of Deep Blue, IBM's Chess Computer

On July 29, 1997, IBM researchers were awarded a $100,000 prize that had gone unclaimed for 17 years. It was the Fredkin Prize, created by Carnegie Mellon University (CMU) professor Edward Fredkin in 1980. An artificial intelligence pioneer, Fredkin challenged fellow computer scientists to create a computer that could beat the best human chess player in the world. That's exactly what Deep Blue did in May, 1997.

It was an extremely long road to victory. After Fredkin's initial challenge in 1980, a team from Bell Labs created a chess computer in 1981 that beat a chess master. In 1985, Feng-hsiung Hsu created ChipTest, a chess computer that set the stage for later efforts.

By 1988, a CMU team including Hsu created a system that beat an international master. That one was called "Deep Thought," named for the computer in The Hitchhiker's Guide to the Galaxy—a fictional computer spent 7.5 million years calculated "the Answer to The Ultimate Question of Life, the Universe, and Everything." (That answer, of course, was 42.)

Deep Thought underwent additional development at IBM, and in 1989 it went head-to-head with Garry Kasparov, who is widely considered the best chess player of all time. Kasparov destroyed the machine in a two-game match. Here's the first part of a documentary about Deep Thought, which helps set the stage for Deep Blue:

Deep Thought eventually led to Deep Blue, an IBM project led by Hsu, along with his former Deep Thought collaborator Murray Campbell, among others.

The computer science problem of chess is deep. First the machine needs to understand the state of the board—that's relatively easy—but then it needs to predict future moves. Given that the 32 pieces on the board are capable of moving to a variety of other positions, the "possibility space" for the next move (and all subsequent moves) is very large.

In theory, a sufficiently beefy computer could simulate every possible move (and counter-move) in its memory, rank which moves end up doing best in each simulated game, and then perform the optimal move on each turn. But to actually implement a computer that powerful—and fast enough to compete in a time-limited tournament—was a matter of extreme effort. It took Hsu more than a decade to master it.

On February 10, 1996 in Philadelphia, Deep Blue went head-to-head with Kasparov, and Kasparov beat the computer handily. Though Deep Blue scored one winning game and two draws, it lost three games to Kasparov outright. Deep Blue did set a record for winning that one game, but it needed the match to earn the Fredkin Prize.

By this point, Kasparov was used to destroying chess computers, and the media lapped it up—this was a man-versus-machine story for the ages. By May 1997, IBM had heavily upgraded Deep Blue (some called it "Deeper Blue") with vastly improved computing resources, preparing for a rematch. When that rematch came, Kasparov would face a worthy opponent.

On May 11, 1997 in New York City, the upgraded Deep Blue entered the match with a large, excited audience. Kasparov won the first game, but Deep Blue took the second, tying the players. Then came three games that ended in draws. In the sixth game, Kasparov made a mistake in the opening. Deep Blue won that sixth game quickly, winning the match, much to the astonishment of the crowd. Kasparov asked for a rematch. The Deep Blue team declined.

Kasparov claimed to have perceived a human hand in Deep Blue's play. Kasparov wondered whether a human chess player was somehow feeding the computer moves, much like the infamous Mechanical Turk of yore. Various conspiracy theories flourished, but came to nothing.

When the Fredkin Prize was awarded to Hsu, Campbell, and IBM researcher A. Joseph Hoane Jr., Fredkin told reporters, "There has never been any doubt in my mind that a computer would ultimately beat a reigning world chess champion. The question has always been when." Hsu told The New York Times, "Some people are apprehensive about what the future can bring. But it's important to remember that a computer is a tool. The fact that a computer won is not a bad thing."

When it comes to furnishing your kitchen with all of the appliances necessary to cook night in and night out, you’ll probably find yourself running out of counter space in a hurry. The ChopBox, which is available on Indiegogo and dubs itself “The World’s First Smart Cutting Board,” looks to fix that by cramming a bunch of kitchen necessities right into one cutting board.

In addition to giving you a knife-resistant bamboo surface to slice and dice on, the ChopBox features a built-in digital scale that weighs up to 6.6 pounds of food, a nine-hour kitchen timer, and two knife sharpeners. It also sports a groove on its surface to catch any liquid runoff that may be produced by the food and has a second pull-out cutting board that doubles as a serving tray.

There’s a 254nm UVC light featured on the board, which the company says “is guaranteed to kill 99.99% of germs and bacteria" after a minute of exposure. If you’re more of a traditionalist when it comes to cleanliness, the ChopBox is completely waterproof (but not dishwasher-safe) so you can wash and scrub to your heart’s content without worry. 

According to the company, a single one-hour charge will give you 30 days of battery life, and can be recharged through a Micro USB port.

The ChopBox reached its $10,000 crowdfunding goal just 10 minutes after launching its campaign, but you can still contribute at different tiers. Once it’s officially released, the ChopBox will retail for $200, but you can get one for $100 if you pledge now. You can purchase the ChopBox on Indiegogo here.

11 Fascinating Facts About Tamagotchi

Tamagotchi is the toy that launched a thousand digital pet competitors.

They blooped and beeped and ate, played, and pooped, and, for ‘90s kids, the egg-shaped Tamagotchi toys were magic. They taught the responsibility of tending to a “pet,” even though their shrill sounds were annoying to parents and teachers and school administrators. Nearly-real funerals were held for expired Tamagotchi, and they’ve even been immortalized in a museum (of sorts). Here are 11 things you should know about the keychain toy that was once stashed in every kid’s backpack.

1. The idea for the Tamagotchi came from a female office worker at Bandai.

Aki Maita was a 30-year-old “office lady” at the Japanese toy company Bandai when inspiration struck. She wanted to create a pet for kids—one that wouldn't bark or meow, make a mess in the house, or lead to large vet bills, according to Culture Trip. Maita took her idea to Akihiro Yokoi, a toy designer at another company, and the duo came up with a name and backstory for their toy: Tamagotchis were aliens, and their egg served as protection from the Earth’s atmosphere. They gave prototype Tamagotchis to high school girls in Shibuya, and tweaked and honed the design of the toy based on their feedback.

2. The name Tamagotchi is a blend of two Japanese words.

The name Tamagotchi is a mashup between the Japanese words tamago and tomodachi, or egg and friend, according to Culture Trip. (Other sources have the name meaning "cute little egg" or "loveable egg.")

3. Tamagotchis were released in Japan in 1996.

Bandai released the Tamagotchi in Japan in November 1996. The tiny plastic keychain egg was equipped with a monochrome LCD screen that contained a “digital pet,” which hatched from an egg and grew quickly from there—one day for a Tamagotchi was equivalent to one year for a human. Their owners used three buttons to feed, discipline, play with, give medicine to, and clean up after their digital pet. It would make its demands known at all hours of the day through bloops and bleeps, and owners would have to feed it or bathe it or entertain it.

Owners that successfully raised their Tamagotchi to adulthood would get one of seven characters, depending on how they'd raised it; owners that were less attentive faced a sadder scenario. “Leave one unattended for a few hours and you'll return to find that it has pooped on the floor or, worse, died,” Wired wrote. The digital pets would eventually die of old age at around the 28-day mark, and owners could start fresh with a new Tamagotchi.

4. Tamagotchis were an immediate hit.

The toys were a huge success—4 million units were reportedly sold in Japan during their first four months on shelves. By 1997, Tamagotchis had made their way to the United States. They sold for $17.99, or around $29 in today's dollars. One (adult) reviewer noted that while he was "drawn in by [the Tamagotchi's] cleverness," after several days with the toy, "the thrill faded quickly. I'm betting the Tamagotchi will be the Pet Rock of the 1990s—overwhelmingly popular for a few months, and then abandoned in the fickle rush to some even cuter toy."

The toy was, in fact, overwhelmingly popular: By June 1997, 10 million of the toys had been shipped around the world. And according to a 2017 NME article, a whopping 82 million Tamagotchi had been sold since their release into the market in 1997.

5. Aki Maita and Akihiro Yokoi won an award for inventing the Tamagotchi.

In 1997, the duo won an Ig Nobel Prize in economics, a satiric prize that’s nonetheless presented by Nobel laureates at Harvard, for "diverting millions of person-hours of work into the husbandry of virtual pets" by creating the Tamagotchi.

6. Tamagotchis weren't popular with teachers.

Some who grew up with Tamagotchi remember sneaking the toys into school in their book bags. The toys were eventually banned in some schools because they were too distracting and, in some cases, upsetting for students. In a 1997 Baltimore Sun article titled “The Tamagotchi Generation,” Andrew Ratner wrote that the principal at his son’s elementary school sent out a memo forbidding the toys “because some pupils got so despondent after their Tamagotchis died that they needed consoling, even care from the school nurse.”

7. One pet cemetery served as a burial ground for expired Tamagotchi.

Terry Squires set aside a small portion of his pet cemetery in southern England for dead Tamagotchi. He told CNN in 1998 that he had performed burials for Tamagotchi owners from Germany, Switzerland, France, the United States, and Canada, all of whom ostensibly shipped their dead by postal mail. CNN noted that "After the Tamagotchis are placed in their coffins, they are buried as mourners look on, their final resting places topped with flowers."

8. There were many copycat Tamagotchi.

The success of the Tamagotchi resulted in both spin-offs and copycat toys, leading PC Mag to dub the late ’90s “The Golden Age of Virtual Pets.” There was the Digimon, a Tamagotchi spin-off by Bandai that featured monsters and was marketed to boys. (There were also Tamagotchi video games.) And in 1997, Tiger Electronics launched Giga Pets, which featured real animals (and, later, dinosaurs and fictional pets from TV shows). According to PC Mag, Giga Pets were very popular in the United States but “never held the same mystique as the original Tamagotchi units.” Toymaker Playmates's Nano Pets were also a huge success, though PC Mag noted they were “some of the least satisfying to take care of."

9. Rare Tamagotchis can be worth a lot of money.

According to Business Insider, most vintage Tamagotchis won't fetch big bucks on the secondary market. (On eBay, most are priced at around $50.) The exception are rare editions like “Yasashii Blue” and “Tamagotchi Ocean,” which go for $300 to $450 on eBay. As Complex notes, "There were over 40 versions (lines) of Tamagotchi released, and each line featured a variety of colors and variations ... yours would have to be one of the rarest models to be worth the effort of resale."

10. A new generation of Tamagotchis were released in 2017 for the toy's 20th anniversary.

In November 2017, Bandai released a 20th anniversary Tamagotchi that, according to a press release [PDF], was "a first-of-its-kind-anywhere exact replica of the original Tamagotchi handheld digital pet launched ... in 1996." However, as The Verge reported, the toys weren't an exact replica: "They're about half the size, the LCD display is square rather than rectangle, and those helpful icons on the top and bottom of the screen seem to be gone now." In 2019, new Tamagotchis were released; they were larger than the originals, featured full-color displays, and retailed for $60.

11. The original Tamagotchi’s sound has been immortalized in a virtual museum.

The Museum of Endangered Sounds is a website that seeks to immortalize the digital sounds that become extinct as we hurtle through the evolution of technology. “The crackle of a dial-up modem. The metallic clack of a 3.5-inch floppy slotting into a Macintosh disk drive. The squeal of the newborn Tamagotchi. They are vintage sounds that no oldies station is ever going to touch,” The Washington Post wrote in a 2012 profile of the museum. So, yes, the sound of that little Tamagotchi is forever preserved, should it someday, very sadly, cease to exist completely.
