What has six colors, six faces, and can frustrate most people? A Rubik’s Cube! Sunday, January 29th, is National Puzzle Day! Puzzles are fun activities that are good for your brain. It exercises your brain to think in different ways. There are many different types of puzzles: crossword puzzles, sudoku, riddles, and more. Rubik’s Cube is a physical and mental puzzle that requires a lot of practice!

Rubik’s Cube is a puzzle game invented by the Hungarian professor and puzzle enthusiast Ernö Rubik in 1974. The puzzle takes the form of a cube. Each face of the cube features a three-by-three grid of colored blocks. The blocks are connected to a central core in such a way that rows of blocks can be moved by twisting. Play begins by twisting the cube at random to scramble the colors. The player solves the puzzle by returning each side of the cube to a single color. Rubik’s Cube has become a pop culture icon. It has earned a place in the Strong National Toy Hall of Fame in Rochester, New York, and the collection of the Museum of Modern Art in New York City.

Rubik was born July 13, 1944, in Budapest, Hungary. He trained as an architect and later taught at the Academy of Applied Arts and Crafts in Budapest. In 1974, Rubik used an early version of his puzzle game to teach his students about three-dimensional movement. His students loved the game. Rubik began selling his invention under the name Magic Cube in Hungarian toy shops in 1977. By 1980, his invention caught the attention of the Ideal Toy and Novelty Company, which licensed it. The company renamed the puzzle Rubik’s Cube. In just under two years, they sold over 100 million cubes.

The simple cube has been modified a few times over the years. Some later versions include larger grids of colors and different shapes. The construction of the Rubik’s Cube has also been improved—making the puzzle easier to twist and more durable—to aid in speedcubing competitions. In speedcubing, Rubik’s Cube fans compete to see who can solve the puzzle the fastest. Occasionally, additional challenges are added. These challenges may include solving the puzzle one-handed or even while juggling three cubes at the same time. In 1982, the puzzle was solved in 22.9 seconds at the first-ever Rubik’s Cube World Championships in Hungary. In later competitions, the puzzle has been solved in under 4 seconds.

Over the past several years, the European Union (EU) has been faced with a growing problem—a trickle of migrants and refugees has become a flood of people trying to gain entry to EU nations. This week, the problem became acute in Budapest, Hungary.

According to the United Nations (UN), migrants are people seeking to live in a new country for economic reasons. They are from poor nations and believe they will have a better standard of living in a wealthier nation. Refugees are people fleeing to a new country because of dangerous conditions in their own nation. Such conditions may include war; famine; or persecution based on religion, nationality, or political or other beliefs.

Many migrants, often from African nations, arrive by sea in dangerous ships not fit to use as transportation. Greece and Italy have been frequent destinations for migrants, and both southern coastal nations have been hard-pressed to mount rescues for those who encounter difficulties on their journey. In 2015 alone, more than 2,000 migrants have died crossing the Mediterranean Sea in an attempt to reach Europe.

Refugees from Syria and other war-torn regions of the Middle East also take a dangerous sea journey. After their arrival in Greece, they tend to travel overland to Macedonia, through Serbia and Hungary, hoping to arrive in Germany. Thus far in 2015, nearly 500,000 people have entered Europe hoping to find a new home. It is the greatest movement of refugees in Europe since World War II (1939-1945).

On Tuesday, September 1, the lives of many mostly Syrian refugees became even harder when the nation of Hungary closed its train station in Budapest and refused to allow refugees to board trains for their final destination countries of Austria and Germany. The government of Hungary’s Prime Minister Viktor Orban cited EU rules that state that refugees must be issued documents upon their arrival in Europe by the nation in which they landed. Orban claimed all refugees must be documented by Hungary before traveling on to Germany.

The scene in and outside the Keleti train station in Budapest was one of chaos. For the first two days, the train station was closed to refugees. Some 2,000 refugees slept outside the train station with no shelter or toilets. As of this morning, the station was reopened to the Syrians, although they are still not allowed to travel on trains out of Budapest. Even with the station as a shelter, services for many people are not available from the Hungarian government.

Russia reportedly has demanded the surrender of Ukrainian forces in Crimea. There are reports that the Russian military has given Ukrainian forces in Crimea an ultimatum to surrender tonight by 10:00 pm EST or face a full military assault. With Russian troops surrounding Ukrainian bases and airports and manning roadblocks that have cut Ukrainian access to the peninsula, Russia is, in effect, already in control of Crimea, the southern most region of Ukraine.

After already having ordered thousands of troops into Ukraine, President Vladimir Putin on March 1 received  authorization from the Russian parliament to deploy armed forces “on Ukrainian territory.” Correspondents reported that the road from Sevastopol to Simferopol, the provincial capital, quickly filled with Russian army trucks.

Ukraine’s acting president, Oleksandr Turchynov, subsequently announced that he had put Ukraine’s armed forces on full readiness because of “potential aggression” from the estimated 15,000 Russian troops crossing into Crimea.

In a heated, 90-minute telephone conversation on March 1, President Putin informed U.S. President Barack Obama that Russia had the right to protect its interests and those of Russian speakers not only in Crimea but also in east Ukraine. After the conversation, President Obama expressed his deep concern over Russia’s clear violation of Ukrainian sovereignty and territorial integrity, which he characterized as  a “breach of international law.”

In a video address on her website, former Ukrainian Prime Minister Yulia Tymoshenko declared on March 2 that by occupying Crimea, Russia has effectively “declared war” on the United Kingdom and the United States. According to Tymoshenko, British and U.S. representatives in 1994 signed the “Budapest Memorandum” guaranteeing Ukraine’s security. “Vladimir Putin is fully conscious that by declaring war, he is also declaring war on the guarantors of our security, the United States and Britain,” she noted.

European Union foreign ministers went into session today in Brussels to discuss possible punitive steps against Russia unless it pulls its troops back to its own bases in Crimea. British Foreign Secretary William Hague urged Russia to pull back its forces in Crimea or face “significant costs,” echoing comments made by U.S. President Obama and Secretary of State John Kerry. “The world cannot just allow this to happen,” Hague told the BBC. “The world cannot say it’s O.K. in effect to violate the sovereignty of another nation in this way.” However, the governments of France and Germany have made it plain that the imposition of economic sanctions on Russia is not on the table, let alone a military intervention. International affairs experts note that much of the European Union is highly dependent on Russian oil and natural gas.  In 2007, EU countries imported from Russia 32.6 percent of their total oil imports and 38.7 percent of total natural gas imports.

The people of Ukraine are split over their attitudes toward East and West. Crimea as well as eastern Ukraine is largely populated with Russian-speaking people with close historic and cultural ties to Russia. Western Ukraine is largely populated with Ukrainian-speaking people who want Ukraine allied with the European Union and the West. Today, pro-Russian demonstrators marched in the streets of the big cities of eastern Ukraine, voicing their allegiance to Moscow. In the city of Donetsk, about 1,000 demonstrators, waving Russian flags and shouting, “Putin, come!” occupied the first floor of the regional government building that has already been flying the Russian flag for several days.
