15-puzzle




According to contributing writer Matthew Woo, the epidemic started in the United States for a few months, then spread to Europe, Australia and even New Zealand. The epidemic turned out to be a challenging, machine-like game, 15- puzzle. It’s a four-by-four grid with 15 numbered tiles that you have to slide around to put in numerical order.

The game became popular a few months after its release in 1880. “It has become literally an epidemic all over the country,” wrote The Weekly News-Democrat in Emporia, Kansas, on March 12, 1880. “Whole cities are distracted, and men are losing sleep and going crazy over it.”It was something that the world had never seen before.




Nearly 140 years later, the 15-puzzle is starting to become popular again, this time not as a distraction, but as a way to understand a seemingly unrelated and much more complex puzzle: how magnets work. Using the mathematics of the 15-puzzle, they expanded a well-known theorem that describes an idealized case of itinerant ferromagnetism. “Itinerant ferromagnetism is actually one of the hardest problems in theoretical condensed matter physics,” said Yi Li, a physicist at Johns Hopkins University. The puzzle uses ferromagnesium to keep the difficulty level above standard.



Here’s a picture of a representation of ferromagnetism




This puzzle will soon be solved by the most intelligent minds of the world. It may be forgotten or may be advanced within the years. With the next few generation magnetism will be so more advanced and may be in everything around us! I think magnetism and electricity are going to be EVERYWHERE within the next 3 years. Hope you enjoyed reading!

Force and Motion

Zach Fluck Science blog Force and Motion Blog Sir Isaac Newton was an English astronomer, physicist, and mathematician, born on December 25, 1642. He died on March 20, 1727, most likely from mercury poisoning or old age. However, during his life, he made several contributions to modern science and advanced our understanding of physics tremendously. Arguably his most famous discovery was gravity. However, he had to use his 3 laws of motion to make this accomplishment. Newton understood that an object at rest will stay at rest, unless acted on by unbalanced forces. Therefore, if an object such as an apple is in a resting position there must be a force to make the apple fall to the ground. He discovered this invisible force to be gravity. At a young age Newton was removed from school to be a farmhand. Despite returning to school the turning point in his live was he left his hometown to attend Cambridge University. After attending Cambridge he returned to his hometown where his observat...

Chemically termolecular reactions: The fourth class of chemical reactions

Chemically termolecular reactions: The fourth class of chemical reactions Maisy Chase Up until now only three classes of chemical reactions were known. Unimolecular reactions occur when one reactant undergoes bond breaking or forming to create different products. Bimolecular reactions are where two reactants collide and then undergo bond breaking or forming. Termolecular association reactions, where two reactants collide to form a whole with a new chemical bond between the two reactants. A third molecule, known as the bath gas, then removes some of the internal kinetic energy of that molecule to stabilize it. Researchers from Columbia University , led by Assistant Professor of Mechanical Engineering Michael P. Burke, have discovered a fourth class of chemical reaction known as “chemically termolecular reactions.” This involves the breaking and bonding of three molecules. The team showed that these chemically termolecular reactions not only are major chemical pathways but also ...

Light waves, Mechanical Waves, and Radiation

  By Marc Gabay Waves are a very interesting topic, if you take the time to think about it thoroughly; for example, light waves or radiation. The kinds of light waves from our sun are visible light ways. On average, it takes roughly 8 minutes and 20 seconds for the sun's light rays to reach Earth. That being said, if the sun were to suddenly disappear out of the universe, it would take a little more than 8 minutes before we realized it was getting a bit chilly. Light travels fast, however space is so big and vast that it takes many years even for distant stars, galaxies, and/or planets to even come into sight. As a result of this, as we look onward into space, we're really looking back into time. Light waves are very interesting this way. Next, Another way that light waves are interesting is that they affect the human body in both positive and negative ways. These types of light waves can be UV light waves or infrared waves. Infrared radiation is pretty much just heat. Thi...
