Fact Fragments – Sharks, Cards, Mountains and Spanish

The highest mountain we know of has yet to be visited, it’s on Mars. We call it Olympus Mons. At 27km from its base to its peak, over 3 times the height of Everest, it is the greatest mountain in the solar system.

More than just tall, it is 550km wide, and is bent around the curvature of Mars itself. So pronounced is the effect that were you to stand on the peak of Olympus Mons, you wouldn’t be able to see the bottom of the mountain, as it would be hidden beyond the horizon. This size is a grand thing indeed, the whole mountain is surrounded by a moat up to 3km deep in some places. Nothing dug it, the sheer weight of it is great enough to literally dent Mars.

 The phrase ‘bla bla bla’ isn’t English, it’s translated directly from Spanish as a shortened version of ‘habla habla habla’ meaning ‘speak speak speak.’

The four suits of cards have peculiar origins, they were initially designed to represent the four major feudal classes of the middle ages. Hearts represents the church, spades represents the military, clubs represents agriculture and diamonds represented the merchant class.

Another quirk of playing cards is the very ornate ace of spades (or ‘spadille’). This comes from the 18th Century where cards would be hand stamped on the ace of spades to show that stamp duty had been paid. Later the ace of spades was stamped in different methods until 1862 when card-makers were free to do what they wanted with their cards due to stamp duty changes. They just left the ace of spades ornate, and so we reach playing cards today.

To finish, let’s talk about sharks. How do you attract a shark? The answer is sound. For a long time it has been known that sound can have a very powerful effect on sea creatures, with sonar from ships being the main cause of whales getting confused, lost and eventually beaching themselves. However new research has shown that some sounds truly entice.

After extensive trial and error it has been found that lower frequencies are much more appealing to great white sharks. Particularly effective is AC/DC, and the most stimulating track of all is the aptly named ‘If You Want Blood’. So, if you’re planning to serenade a great white shark, you know what to do.
