This is a map that takes some time to get your head around; quite literally, because to appreciate it fully, you need to consider it both with its north side and its south side up [1].

To spare you the risk of neck injury, we're providing both versions: first with north on top, then south. And what do you know? There is no right side up -- or rather: there is no wrong side up. For this is a planisphere [2] palindrome, a planet-chart that can be 'read' the same way 'upside up' and upside down.

This is very strange. The size and distribution of the world's continents and oceans is random, the result of millions of years of continental drift. That process is still ongoing [3]: the way the world looks like on our maps is but a snapshot, even if it feels like an eternity from our human perspective.
It would seem impossible to find a pattern with global consistency in that random jumble of land masses and water bodies. A map showing the overlap of antipodean dry lands [4] doesn't seem to indicate any, at least. But the Italian artist Giacomo Faiella did find such a pattern.
In the 'upside up' version, the continents are a solid, walkable blue, the seas are a foamy yellow-white, and the north pole the frozen colour of ice. The map is centred on China, with Europe and Africa pushed to its western edge, and the Americas near its eastern rim.
Colour codes are relative, as shown by our immediate re-interpretation of them in the 'downside up' version. Here, the continents are the different hues of grass, from green to dry; the ocean is navy blue and it's the South Pole that is frozen, while the North Pole has reverted to open water. In this map, the longitudes of Europe and Africa retain retain the centrality that they are traditionally accorded in Western cartography, while East Asia and the Americas are pushed to the edges.
It's fascinating to see how Mr. Faiella has managed, with some cajoling of geographic veracity, to find correspondences between features on the opposite sides of the world.
The Mediterranean Sea in the 'up' version is Australia in the 'down' one (and vice versa, of course). That little fleck to the south of Australia that represents Tasmania? That's the Adriatic Sea in the other map, between Italy and the former Yugoslav states.
The Black and Caspian Seas to the Mediterranean's east transform into the main western islands of the Indonesian archipelago: Java and Sumatra, respectively. The Red Sea becomes the Philippines, the Persian Gulf the Thai-Malay Peninsula. India, that triangle pointing south, transmogrifies into the adjacent Bay of Bengal, a triangle pointing north.
Fantastically, miraculously, South America becomes the North Atlantic ocean, and the North America continent changes into the South Atlantic. Two dots vaguely reminiscent of the Great Lakes become the (much smaller) Falkland Islands [5].
The two islands of New Zealand transform into the North Sea and the Baltic Sea, with the Cook Strait between both islands becoming the Jutland [6] peninsula of Denmark. The Japanese archipelago corresponds with a string of Africa's Great Lakes, while Madagascar has a ghostly pendant in the Sea of Okhotsk.
And on it goes -- we'll leave you to work out the other correspondences. Like we said, some geographic cajoling has taken place. Australia and New Zealand are nowhere near as close to South America; nor are North America and northern Europe attached to Greenland. You have to squint a little, but this works as a world map. It's incredible that it works as two world maps.

[1] Modern maps are usually oriented towards the north, in the tradition of Ptolemy's Geographia. However, for sacral reasons, maps in the Middle Ages often had east 'up' - hence our word 'orientation'.
[2] Planisphere describes the representation of a globe on a flat surface - i.e. a world map; but also the parking disk-like instrument made up of two adjustable disks rotating on a pivot, used to calculate which stars and constellations are visible in the night sky at any particular time.
[3] It's no coincidence that the eastern shoreline of South America 'fits' with that of western Africa's: both land masses once were part of Pangaea, the single supercontinent that broke up about 200 million years ago. The Atlantic Ocean continues to widen at an annual rate of 25 millimetres (about an inch) -- about the rate your fingernails grow. Back in 1968, an Air France commercial dreamed of the time when it was still no wider than a river. See #474.

Our hearts beat at a resting rate of 60 to 100 beats per minute. Lots of other things pulse, too. The colors we see and the pitches we hear, for example, are due to the different wave frequencies ("pulses") of light and sound waves.
Now, a study in the journal Geoscience Frontiers finds that Earth itself has a pulse, with one "beat" every 27.5 million years. That's the rate at which major geological events have been occurring as far back as geologists can tell.

According to lead author and geologist Michael Rampino of New York University's Department of Biology, "Many geologists believe that geological events are random over time. But our study provides statistical evidence for a common cycle, suggesting that these geologic events are correlated and not random."
The new study is not the first time that there's been a suggestion of a planetary geologic cycle, but it's only with recent refinements in radioisotopic dating techniques that there's evidence supporting the theory. The authors of the study collected the latest, best dating for 89 known geologic events over the last 260 million years:
- 29 sea level fluctuations
- 12 marine extinctions
- 9 land-based extinctions
- 10 periods of low ocean oxygenation
- 13 gigantic flood basalt volcanic eruptions
- 8 changes in the rate of seafloor spread
- 8 times there were global pulsations in interplate magmatism
The dates provided the scientists a new timetable of Earth's geologic history.

Putting all the events together, the scientists performed a series of statistical analyses that revealed that events tend to cluster around 10 different dates, with peak activity occurring every 27.5 million years. Between the ten busy periods, the number of events dropped sharply, approaching zero.
Perhaps the most fascinating question that remains unanswered for now is exactly why this is happening. The authors of the study suggest two possibilities:
"The correlations and cyclicity seen in the geologic episodes may be entirely a function of global internal Earth dynamics affecting global tectonics and climate, but similar cycles in the Earth's orbit in the Solar System and in the Galaxy might be pacing these events. Whatever the origins of these cyclical episodes, their occurrences support the case for a largely periodic, coordinated, and intermittently catastrophic geologic record, which is quite different from the views held by most geologists."
Assuming the researchers' calculations are at least roughly correct — the authors note that different statistical formulas may result in further refinement of their conclusions — there's no need to worry that we're about to be thumped by another planetary heartbeat. The last occurred some seven million years ago, meaning the next won't happen for about another 20 million years.

If you'd like to make smarter choices and sounder decisions — and who doesn't? — you might want to take advantage of a resource you already have close at hand: your interoception. Interoception is, simply stated, an awareness of the inner state of the body. Just as we have sensors that take in information from the outside world (retinas, cochleas, taste buds, olfactory bulbs), we have sensors inside our bodies that send our brains a constant flow of data from within. These sensations are generated in places all over the body — in our internal organs, in our muscles, even in our bones — and then travel via multiple pathways to a structure in the brain called the insula. Such internal reports are merged with several other streams of information — our active thoughts and memories, sensory inputs gathered from the external world — and integrated into a single snapshot of our present condition, a sense of "how I feel" in the moment, as well as a sense of the actions we must take to maintain a state of internal balance.
To understand the role interoception can play in smart decision-making, it's important to know that the world is full of far more information than our conscious minds can process. However, we are also able to collect and store the volumes of information we encounter on a non-conscious basis. As we proceed through each day, we are continuously apprehending and storing regularities in our experience, tagging them for future reference. Through this information-gathering and pattern-identifying process, we come to know things — but we're typically not able to articulate the content of such knowledge or to ascertain just how we came to know it. This trove of data remains mostly under the surface of consciousness, and that's usually a good thing. Its submerged status preserves our limited stores of attention and working memory for other uses.
A study led by cognitive scientist Pawel Lewicki demonstrates this process in microcosm. Participants in Lewicki's experiment were directed to watch a computer screen on which a cross-shaped target would appear, then disappear, then reappear in a new location; periodically they were asked to predict where the target would show up next. Over the course of several hours of exposure to the target's movements, the participants' predictions grew more and more accurate. They had figured out the pattern behind the target's peregrinations. But they could not put this knowledge into words, even when the experimenters offered them money to do so. The subjects were not able to describe "anything even close to the real nature" of the pattern, Lewicki observes. The movements of the target operated according to a pattern too complex for the conscious mind to accommodate — but the capacious realm that lies below consciousness was more than roomy enough to contain it.
"Nonconscious information acquisition," as Lewicki calls it, along with the ensuing application of such information, is happening in our lives all the time. As we navigate a new situation, we're scrolling through our mental archive of stored patterns from the past, checking for ones that apply to our current circumstances. We're not aware that these searches are under way; as Lewicki observes, "The human cognitive system is not equipped to handle such tasks on the consciously controlled level." He adds, "Our conscious thinking needs to rely on notes and flowcharts and lists of 'if-then' statements — or on computers — to do the same job which our non-consciously operating processing algorithms can do without external help, and instantly."
But — if our knowledge of these patterns is not conscious, how then can we make use of it? The answer is that, when a potentially relevant pattern is detected, it's our interoceptive faculty that tips us off: with a shiver or a sigh, a quickening of the breath or a tensing of the muscles. The body is rung like a bell to alert us to this useful and otherwise inaccessible information. Though we typically think of the brain as telling the body what to do, just as much does the body guide the brain with an array of subtle nudges and prods. (One psychologist has called this guide our "somatic rudder.") Researchers have even captured the body in mid-nudge, as it alerts its inhabitant to the appearance of a pattern that she may not have known she was looking for.
Such interoceptive prodding was visible during a gambling game that formed the basis of an experiment led by neuroscientist Antonio Damasio, a professor at the University of Southern California. In the game, presented on a computer screen, players were given a starting purse of two thousand "dollars" and were shown four decks of digital cards. Their task, they were told, was to turn the cards in the decks face-up, choosing which decks to draw from such that they would lose the least amount of money and win the most. As they started clicking to turn over cards, players began encountering rewards — bonuses of $50 here, $100 there — and also penalties, in which small or large amounts of money were taken away. What the experimenters had arranged, but the players were not told, was that decks A and B were "bad" — they held lots of large penalties in store — and decks C and D were "good," bestowing more rewards than penalties over time.

As they played the game, the participants' state of physiological arousal was monitored via electrodes attached to their fingers; these electrodes kept track of their level of "skin conductance." When our nervous systems are stimulated by an awareness of potential threat, we start to perspire in a barely perceptible way. This slight sheen of sweat momentarily turns our skin into a better conductor of electricity. Researchers can thus use skin conductance as a measure of nervous system arousal. Looking over the data collected by the skin sensors, Damasio and his colleagues noticed something interesting: after the participants had been playing for a short while, their skin conductance began to spike when they contemplated clicking on the bad decks of cards. Even more striking, the players started avoiding the bad decks, gravitating increasingly to the good decks. As in the Lewicki study, subjects got better at the task over time, losing less and winning more.
Yet interviews with the participants showed that they had no awareness of why they had begun choosing some decks over others until late in the game, long after their skin conductance had started flaring. By card 10 (about forty-five seconds into the game), measures of skin conductance showed that their bodies were wise to the way the game was rigged. But even ten turns later — on card 20 — "all indicated that they did not have a clue about what was going on," the researchers noted. It took until card 50 was turned, and several minutes had elapsed, for all the participants to express a conscious hunch that decks A and B were riskier. Their bodies figured it out long before their brains did. Subsequent studies supplied an additional, and crucial, finding: players who were more interoceptively aware were more apt to make smart choices within the game. For them, the body's wise counsel came through loud and clear.
Damasio's fast-paced game shows us something important. The body not only grants us access to information that is more complex than what our conscious minds can accommodate. It also marshals this information at a pace that is far quicker than our conscious minds can handle. The benefits of the body's intervention extend well beyond winning a card game; the real world, after all, is full of dynamic and uncertain situations, in which there is no time to ponder all the pros and cons. When we rely on the conscious mind alone, we lose — but when we listen to the body, we gain a winning edge.
