Challenge Your Mind: Solve These 7 Christmas Puzzles in 10 Minutes – Only for Geniuses!

1. Snow Problem

Raymond gazed out his window and admired the snow-covered garden, where a perfect layer of 5 centimeters blanketed everything except the path. The snow was already beginning to melt.

The rectangular garden measures 16 meters on its longest side and 10.5 meters on the shorter side. The path is a narrow rectangle, 0.5 meters wide, leading from the street to the entrance.

Raymond started some rough calculations. We built a snowman made of three spheres, where the volume ratio of base, thorax, and head is 3:2:1.

His calculations use a simplified method which takes 4 times the cube of the radius for the sphere’s volume and overlooks snow compaction.

Based on this method, can you determine the radius of the snowman’s base sphere?

2. Insulation Calculation

Sven Svendsen is almost ready for his North Pole expedition. An essential part of his preparation involves gaining weight for warmth.

Beginning today, he will start with his normal daily intake of 2,540 calories and will increase his calorie consumption by 100 calories each day over the next 20 days.

Sven plans to gain weight solely by consuming Wazoo multi-nutrient bars, each containing 140 calories.

How many days can he stick to this plan, only eating Wazoo bars?

3. Advent Attempt

In December, a daily contest challenges players to guess a number between 1 and 10,000. A single lucky number will win a prize, remaining unchanged throughout the month. Incorrect guesses allow players to try again the next day.

In one household, Steve guesses daily, while his daughter Lottie has an advent calendar with 24 doors but doesn’t understand numbers yet. She can only open one door each day.

After Steve guesses three numbers and Lottie opens her three doors on December 3rd, who is more likely to have chosen correctly: Lottie with her doors or Steve with his numbers?

Answers

Snow Problem

Solved: 1 meter

Explanation: The garden’s area measures 168m² (10.5m x 16m). The path, being 0.5m wide and 16m long, occupies 8m². Thus, the snow-covered garden area is 160m². At a depth of 5 cm, the snow volume equals 160 x 0.05 = 8m³.

To find the snowman’s base volume, half of the snow (4m³) is used. The formula for a sphere’s volume leads to the equation 4r³ = 4m³, resulting in a base radius of 1 meter with a diameter of 2 meters.

Insulation Calculation

Solved: 3 days

Explanation: Begin by determining a target calorie value that divides evenly by 140. 2,940 is one such number (140 x 21). You can increase this by adding or decreasing 100 calories weekly. Thus, 2,240, 2,940, 3,640, and 4,340 are attainable calorie goals. By starting at 2,540 calories and incrementing daily over 20 days, you can reach 4,540 calories. The viable calorie values therefore yield three days of consuming only Wazoo bars.

Advent Attempt

Solved: It is more likely that Lottie opened the correct three doors in any order.

Explanation: Lottie opened three out of 24 doors on day one, two out of 23 on day two, and one out of 22 on day three. The probability of her correctly opening the doors multiplies, giving 6/12,144. Conversely, the chances of Steve guessing the lucky number are only 3/10,000. Therefore, Lottie has better odds of success.

PIN Puzzle

Solved: Janice’s PIN is 3552.

Explanation: To find a three-digit number, valid combinations must not include digits greater than 5. Acceptable pairs like (5,2,1) and (4,3,1) yield 6 permutations each. The sum of all configurations is calculated to determine her PIN as 3552.

AI can rapidly decode digital data stored in DNA in a matter of minutes instead of days

DNA can store digital data such as visual and audio files

Artificial intelligence can read data stored in DNA strands within 10 minutes, not the day required for previous methods, and DNA storage approaches practical use of computing.

“DNA stores huge amounts of data in a very compact form and remains intact for thousands of years.” Daniella Bar-Lev At the University of California, San Diego. “In addition, DNA is naturally replicable and offers a unique advantage for long-term data storage.”

However, getting encoded information within DNA is a monumental challenge as the strands become confused when mixed and stored. During the data encoding process, individual strands may be replicated incompletely, and some fragments may be lost completely. As a result, data readings stored in DNA are similar to reconstructing books from boxes filled with pages that go beyond the finest, varied.

“The traditional methods suffer from this confusion and require several days of processing,” says Bar-Lev. The new approach “rationalizes this with AI trained to find patterns of noise,” she says.

Bar-Lev and her colleagues developed an AI-driven method called DNAFormer. The system includes a deep learning AI model trained to reconstruct DNA sequences, another computer algorithm to identify and correct errors, and a third decoding that brings everything back to digital data while correcting any remaining mistakes. Includes algorithms.

In experiments, DNAFormer can read 100 megabytes of DNA storage data 90 times faster than the next fastest method developed with traditional rules-based computing algorithms, while achieving better or equivalent accuracy. I did. The decoded data included colored images of the test tube, a 24-second audio clip from astronaut Neil Armstrong's famous Moonlanding speech, and text on why DNA is a promising data storage medium .

The team says they plan to develop a version of DNAFormer tailored to new technologies for encoding data into DNA. Omar Savery Technion – Israel Institute of Technology.

“Crucially, our approach doesn't rely specifically on us. [DNA] Synthesis or sequencing methods can be adapted to future, still undeveloped technologies that are more commercially viable,” he says.

Australian Museums Utilize Technology to Engage Visitors with Volcanic Explosions every 15 minutes

IIt begins with a soft rumble, then an explosion, and finally a thunderous roar. Pyroclastic flows spew out from volcanoes and race towards us at alarming speeds. A cascade of volcanic ash seems to be pelting the surrounding space – technically, it’s the distinctive pumice gravel from Mount Vesuvius – and for a few moments, patrons at the National Museum of Australia are transported to the 1,946-year-old tragedy in Pompeii.

Immersive experiences, including increasingly advanced virtual reality technology, are gaining popularity in museums despite criticism from scholars that flashy special effects may divert viewers from the actual artifacts and exhibits. It has shifted from being a mere gimmick to a successful exhibition to a crucial component in educating future generations, assuming that the primary purpose of museums is entertainment.

Laurent Dondy, the head of development and international tours at Grand Palais Immersif, the French company involved in creating Pompeii, acknowledges some of the apprehensions regarding immersive technology in museums.

“Sorry, but I don’t want to see Van Gogh smoking or scratching his head,” he explains. “Our approach is a blend of art and science. Technology plays a role in the creative process that surprises people and can undoubtedly add a layer of enjoyment to the experience.”

Pompeii is now on display at the National Museum of Australia in Canberra, offering hourly exhibitions showcasing Mount Vesuvius. While the immersive encounter is included in the admission price, other high-budget productions in Australia necessitate separate headsets and seats due to technology requirements, resulting in extra charges that can escalate the cost of a family day at the museum to hundreds of dollars.

Over 500,000 individuals attended the record-breaking ‘Ramses and the Gold of the Pharaohs’ exhibition at the Australian Museum in Sydney, with a quarter opting for the additional $30 fee for the VR component per person. We decided to queue for the opportunity to participate.

The Australian Museum’s latest hits, Machu Picchu and the Golden Empire of Peru, mark the museum’s fourth stage production with an immersive element.

And according to its director Kim McKay, this technology is here to stay.

“In today’s world, we must provide people with experiences, and I believe museums should not be exempt from that,” she asserts. “Museums need to evolve. Like everything else, we can’t be anchored in the past; we must embrace new and evolving technologies.”

“Children now anticipate digital enhancements, and as museum leaders, it is our responsibility to determine how to effectively integrate this technology to maintain an authentic experience. It’s a fine balance.”

Gedeon Experience, the creative force behind Pompeii’s special effects, gained exclusive access to archaeological digs in inaccessible areas, documenting the daily efforts of archaeologists for two years and using CGI to reconstruct the city’s streets and buildings.

Instead of detracting from the visitor experience, this spectacle enriches and complements the over 90 items borrowed from the Pompeii Archaeological Park, including frescoes, mosaics, jewelry, sculptures, and domestic objects.

The Director of the University of Sydney’s Museums and Heritage Program highlights a prime selection of must-see exhibitions from Australia’s museums and galleries.

However, the drawback is that technology inflates exhibition budgets, leading to increased ticket prices.

“They are costly, and there is fierce competition to incorporate the latest digital technologies,” O’Reilly remarks.

Having attended the initial Pompeii exhibition in Paris in 2020, O’Reilly notes that the visual effects of the exhibition are mostly consistent with other immersive exhibitions encountered abroad over the following four years.

“A well-executed immersive exhibit can provide a profound layering of experience and knowledge, but outdated technology may disappoint some visitors. The pace of [developments] is incredibly rapid,” she observes.

“The audience is quite demanding. Game resolutions are astoundingly high. For immersive content and narrative delivery, we now expect the caliber we encounter in gaming. It’s an intimate, detailed experience, and museum-goers will anticipate a commensurate level of quality.”

Is there a risk that future generations lacking technological acumen may fail to grasp the significance of the displayed artifacts?

“Possibly, but without those innovations to begin with, they might not have engaged in the first place,” O’Reilly remarks. “Their expectations will differ from those of previous generations.”

Perhaps not. McKay recounts that when the Australian Museum polled 100 children about their desires for future museums, they anticipated “screens everywhere.”

“That wasn’t the case. They requested ‘more spiders, more sharks, more snakes.’ They sought greater authenticity,” she concludes.

The Genius Behind a Game: How a Developer Earned £250,000 in Just 30 Minutes

Game development is an expensive and time-consuming business. Currently, he has 2,000 people working in 18 studios around the world on the next installment of Ubisoft’s blockbuster Assassin’s Creed series, a project that will take two to three years. Last year, the self-taught programmer learned that he earned nearly £280,000 for a series of games he made sitting in his two-bedroom flat in Harlesden, pants on, on a hot day. Imagine how people would feel. And each one took about 30 minutes.

“The first one probably took seven to eight hours, to be honest,” TJ Gardner says. “But later pieces, like ‘Stroke the Beaver,’ would take about 30 minutes.”

Gardner is the author of the “Stroke” video game, which can be downloaded from the PlayStation Store for £3.29 each. Each features different animals such as cats, dogs, and hamsters, as well as less cute creatures such as snakes and fish, and all follow the same blueprint.

When you start the game, you will see images of animals on a plain blue background. In the upper left corner of the screen you will see the words “Stroke 0”. Press X to pet the animal. The animal blinks briefly. The number in the corner increases by one. After 25 strokes, you will be awarded a bronze trophy. If you keep going until you reach 2,000 strokes, you’ll earn the Platinum award.

That’s all. There are no animations. There are no sound effects. Just pictures of animals under Wikipedia’s Creative Commons license and his lo-fi acoustic beats looping endlessly in the background. No running, no jumping, no guns, no bad guys, no special moves, no power-ups, no puzzles. Is Stroke Game a video game at all?

“It depends on how you define ‘game,'” Gardner says. “There is interaction. Sure, that interaction is very limited, but it’s there and there is a goal. I’m willing to admit that it’s not difficult and it’s not complicated, but it’s still video It’s a game.”

Looking at the numbers Mr. Gardner provided, perhaps that might not be a problem, at least for his bank managers. Since its launch in September 2022, the Stroke game has been downloaded over 120,000 times and generated sales of over £275,000. He will receive a 30% cut from Sony hosting the game on his PlayStation Store, leaving Mr Gardner with his pre-tax profit of more than £190,000.

People don’t buy these titles for addictive gameplay, engaging stories, or dizzying visuals. So what’s its appeal?

It all started in the mid-2000s, when console manufacturers started awarding virtual accolades to players who completed additional in-game goals. These are called achievements on Xbox and trophies on PlayStation. A new subculture was born, established by a community of gamers who played for the prize rather than the fun. They are known as trophy hunters. In pursuit of glory, some people will stop at nothing to play Hannah Montana: The Movie: The Game.

The PlayStation Store now has dozens of games aimed at these players. It’s a low-cost, laughably simple title that offers easy trophies in exchange for a few pounds. Gardner, who had a partner and young children to support, had recently taught himself to code (mainly from his YouTube videos and his tutorials online) and saw an opportunity.

“It was kind of tough for a young family to go paycheck to paycheck,” he says. According to Gardner, at the time anyone could apply for a game to be sold on his PlayStation Store and submit a design document outlining how it would work. “When we looked into Sony’s backend, we found that it’s actually very easy to get through quality assurance,” he says. In 2022, his first game, his Stroke the Dog, appeared on the store without any problems. “So we tried a few more, obviously using slightly different animals.”

Stroke the Hamster is a bestseller with over 11,000 downloads. Cats are his second most popular pet animal, followed – perhaps surprisingly – by turtles. But what was the inspiration behind Gardner’s epic Stroke the Beaver?

“To be honest, at one point it was like a joke to me,” he says. “I decided to see how far I could go.'' It seems quite far away. Gardner then released Stroke the Dik-Dik. “It’s an animal, right?”

Not everyone found the game interesting. Internet forums are full of posts criticizing the Trophy Hunter titles, their creators, and Sony for even allowing them to be listed on his PlayStation Store. Gardner acknowledged that Strokes’ game was shovelware, gained some defenders among his critics, and attempted to address the criticisms.

“He saw a gap and took advantage of it,” forum user the1andonly654 wrote. “Give him more power. What company wouldn’t do that?” Call of Duty, FIFA, and Assassin’s Creed are all essentially not that different. ”

Of course, there are big differences in how much time, money, and creative effort goes into those games, and the richness of the experience they provide. But there are similarities in the business models. New installments are frequently created with the aim of exploiting existing markets. The focus is on reskinning the visuals rather than developing new ideas.

There’s an argument to be made that Gardner’s Stroke game represents a more honest trade than, say, a randomized loot box with in-game rewards. At least when he buys a Stroke game, Gardner says, “you know exactly what you’re buying.” There is nothing there to take advantage of you. Or nothing to suggest you need to buy anything else. You don’t have to buy it if you don’t want to. He didn’t have many complaints. Of the 11,105 people who bought Stroke the Hamster, he asked only 10 people to buy it. Refund.

But the critics remain, and it appears Sony is listening. Platform holder in November 2022
It is said that it started The Shovelware crackdown is threatening developers with emails sent to them to delist Trophy Hunter games and suspend their creators’ publisher accounts.

However, it’s hard to see evidence of this policy in action on the PlayStation Store, which is still full of such titles. When Gardner released Stroke the Animals, a gorgeous piece featuring 10 creatures, last December, Sony didn’t seem to mind. (“Do you like Aminares?” [sic], Read game information. “Great!” Well, there’s a lot you can stroke, so start stroking. ) Perhaps it’s not so much a mystery why Sony didn’t crack down. Thanks to his 30% cut, the company made more profits. More than £80,000 for a stroke game.

The first thing Mr. Gardner did with some of his profits was pay off his debts. Then he decided it was time to take his eyes off shovelware. “I’ve reached a stage where I’m willing to try something a little different, because even though it’s making money, it’s not money.” As you can probably imagine, it’s the most rewarding thing. ” One of his new projects is a new website.
Game achievements.net. Launching in the coming months, players will be able to track their in-game awards across multiple platforms.

So does Gardner have any regrets?

“Honestly, no,” he says. “I will never regret anything I did to help my family because I did it for them.”
