Earlier, in 2017, it was declared the “UK Best Heritage attraction”. The spectacular Giant’s Causeway is made of black volcanic rocks (basalt) some 60 million years old. Formed between 50 and 60 million years ago, the 'causeway' takes its name from the legends of Finn MacCool and draws people from far and wide to this corner of north Antrim. Although we mostly associate hexagons with honeycomb patterns in beehives, this shape can also be found across the world in lava formations, specifically columnar basalt, a common type of lava. Take this quiz to find out. This quirky natural phenomenon is the most popular attraction in Northern Ireland, welcoming millions of visitors annually. Walk the Giant's Causeway. It is said that the Causeway is the creation of a giant who once lived there named Finn McCool. The Causeway was created at a fascinating time in the Earth’s history, when the Atlantic Ocean was just beginning to form. Columnar basalt only crystallizes within a lava flow, slowly cooling in a more unusual way. Its 40,000 polygonal basalt columns sticking out of the sea contributed to the development of Earth … You can check that a triangle with an area of 1 must have a perimeter of $\sqrt[4]{432}\approx{4.56}$, a square can enclose 1 square foot with a smaller perimeter of 4, but the winner is the hexagon, which can enclose a unit area with a perimeter of just $\sqrt[4]{192}\approx{3.72}$. Almost identical to the Giant’s Causeway, these basalt columns are perfectly shaped and hexagonal, although a part of the cave itself. You may prefer to argue that of course the hexagons have the smallest perimeter of the three, as they are closest in shape to the circle (which encloses a given area using the least perimeter). For example, there are the Giant’s Loom, the Giant’s Coffin, and the Giant’s Cannons, as well as the Giant’s Eyes. During a recent whirlwind tour of Ireland and Northern Ireland, we visited Giant’s Causeway as do scores of other tourists and locals. Formed 50 to 60 million years ago, during the Paleogene Period, the Giant’s Causeway resulted from successive flows of lava inching toward the coast and cooling when they contacted the sea. My science-wired brain was immediately curious about how such a consistently hexagonal structure forms in nature. View from the Hexagon Rock Formation at the Causeway There are many myths that surround the Giant’s Causeway. That’s right, it’s about a 15-20 minute walk down to the Giant’s Causeway from the Visitor Center itself, but it’s not a hard walk and the scenery along the way is a big part of the experience. Columnar basalt is unlike normal basaltic lava as it cools. When a small segment of the lava flow begins to cool from the inside, it contracts, and it fractures as it does so. Had the lava at Giants Causeway been spewed forth evenly and cooled uniformly, the whole area would be covered in perfect hexagons. (Yes it’s true that nature could choose something more complicated such as the beautiful 3464 tesselation and use a combination of all three, or even the 4-6-12 tesselation that uses dodecagons too, but nature is incredibly efficient and tends to choose the easiest solution to a given problem!). Let’s make life easy for mother nature and give her a choice of the regular shapes proven by mathematics to be the only three that tesselate (completely cover a flat area without leaving any gaps): the triangle, square and hexagon. … Incredibly, the stones are built not by a genius mathematician or engineer but by mother nature. And even its name, Fingal’s cave, echoes the myth about the Giant’s Causeway because in Scottish Gaelic mythology Fingal is the name of Finn MacCool. Northern Ireland's wonder, The Giants Causeway. You see, ol’ Finn McCool long, long ago got a little feisty and challenged a Scot from across the water to a battle. When cooling rates are fairly uniform, with the heat from the lava escaping at regular intervals, it contracts and fractures fairly evenly, leading to tall, well-developed, generally hexagonal basalt columns. When one well-developed, symmetrical hexagonal column forms, therefore, many more tend to form around it, producing magnificent collections of columnar basalt like that seen at the Giant’s Causeway. (any mathematician who dislikes Imperial units may click here to read about the system’s benefits – which include being convenient for approximate measurements). Complimentary audio-guides are also available for visitors whether or not you decide to walk down to the Causeway or take the bus. Now, thanks to a team of researchers at the Dresden University of Technology, this mystery has been solved. The Giant’s Causeway is a spectacular, natural wonder in the UK. We've been back almost a dozen times and every time we're amazed at the (mostly) hexagonal stones jutting majestically from the water's edge. Made up of 40,000 black basalt stone columns placed at the water’s edge, the Giant’s Causeway is an important geologic formation and a World Heritage site. House of Maths School Workshops Primary & Secondary in Dorset & South, CIRCULAR REASONING: TOP TIPS FOR USING A COMPASS, House of Maths School Workshops Primary & Secondary in Dorset & South -. The Giant’s Causeway is spectacular. TRIANGULAR NUMBERS AND PYTHAGOREAN TRIPLES – A SURPRISING RELATIONSHIP. What ever you believe one thing is … One of them is how it got its name. As the rock cools it contracts, and this changing shape means that as it solidifies the rock must crack to release the pressure (similar to the way that an ice cube warms, contracts and cracks when you put it into your drink). Of those three, nature being efficient and beautiful will choose the solution that minimises the amount of cracking it has to effect. The site was declared a World Heritage Site by UNESCO in 1986. From our article on the Geology of the Giants Causeway here, we know how the Causeways 40000 or so Hexagonal shaped columns were actually created, through Volcanic activity around 60 million years ago. Over half a million tourists visit this iconic structure every year and it is easy to see why the appeal never dwindles. Is the Giants Causeway a UNESCO World Heritage Site? It is so unique in its appearance that it is hard to believe it is real. This website uses cookies to improve user experience. In my quest for knowledge, I found a great article […] The article states, "While contraction in the vertical direction reduced the flow thickness (without fracturing), horizontal contraction could only be accommodated by cracking throughout the flow The first time we visited the Giant's Causeway, we knew we would want to return again (and again). The colums of the Causeway were formed some 60 million years ago, as molten lava from a massive eruption that flowed into the sea, cooling rapidly and shrinking into the 40000 hexagonal columns we see today The plinths here are in fact igneous basalt columns, created when molten lava comes up from inside the earth and cools. Those basalt columns are believed to be the result of ancient volcanic eruption which occurred millions of years ago, bringing out those incredible rock formations. While most of the columns had a characteristic hexagonal shape, different rocks had four to eight sides. HOW MOST PEOPLE CAN BE “BETTER THAN AVERAGE”! Cooling lava sometimes forms strange column-shaped formations with a remarkable degree of order. A new study published in the journal Physical Review Letters has solved this conundrum by creating a computer model to work it out. The Giant's Causeway is an area of about 40,000 interlocking basalt columns, WHY ARE THE STONES AT GIANTS CAUSEWAY HEXAGONAL? Either way, hexagonal shaped-columns mostly tend to form, and the precise reason for why this morphology was preferred has remained a mystery. Checking the geology at Giant’s Causeway in the middle of … As cooling continued, these cracks grew larger, forcing the angles to change to 120° – the same angle found in each corner of a hexagon.
