In world’s oceans, you cannot go further from any land than ‘Point Nemo’ before you start coming back. Point Nemo is exactly 2688.22 kilometers (or 1,450 nautical miles) from the nearest land and there’s no other point in ocean that far from the land. It’s named after the fictional character, captain Nemo from Jules Verne’s novel “Twenty Thousand Leagues Under the Sea” published in 1870.
On a planet such as ours with complex landmass and ocean distribution having thousands of islands, some smaller than the size of a football field, finding such point can be challenging. Further such point should be farthest not from one but three coastlines to fulfil the criteria of being farthest from ‘any land’. Fortunately with modern day computational power at hands, finding such a point is not that difficult.
Point Nemo with a geographical coordinates of s48:52:31.748 w123:23:33.069, is 2688 km away from the following three coastlines:
Ducie Island is a non-inhabited small C-shaped strip of land with a diameter of barely two kilometers. Motu Noi is also small piece of land (less than 100 meter across) but it’s near to a well-known bigger island: Rapa Nui or better known as ‘Easter Island’. It’s the Rapa Nui Island where you see those giant stone monolith statues; Moai. The 20km wide volcanic island, Rapa Nui, has its own airport and is a developed tourist destination. The third one, Maher Island is a small piece of land on the outskirts of a larger Siple Island which is the part of Antarctica.
So just in case if you’re stuck somewhere around Point Nemo and decide to come back, your best option is to head North towards Easter Island (of course 2688 km away), appreciate the historical Moai and get a plane back home. [via globecalc]
4. Only 2 percent of the Australian population lives in the yellow area
The total area of Australia is almost equal to that of United States minus Alaska, however, its (Australia’s) population is just 23 million which is less than the population of Texas alone.
5. Since its discovery, Pluto never made a full orbit around the Sun
Pluto takes 248 years to complete its orbit around the sun that our earth completes is just one year.
6. The Diomede Islands are 2.4 miles and One Day apart
The Diomede Islands, just 2.4 miles apart are separated by International Date Line. They are also named “Tomorrow Island” and “Yesterday Island”. Big Diomede belongs to Russia and has a population of zero while the Little one belongs to United States with a population of about 200. Since the big Diomede belongs to Russia, it’s 23 hours ahead of the little Diomede.
You are seeing the map right! Russia and Alaska are indeed this close apart. This is the part where we cut the world map to present it in a planer form instead of a globe.
7. You can actually fly on Saturn’s moon Titan
The gravity is low enough and the atmosphere thick enough on Titan, that by attaching small wings to your arms, you could fly like a bird. The gravitational pull there is seven times less and the escape velocity is four times less than that of the earth.
8. If an alien located 60-65 million light years away from us, looked at earth through a really powerful telescope today, he would see Dinosaurs!
This makes sense since we, at earth, are only able to see the objects in the outer space who’s light has reached us. The Dinosaurs lived on this planet about 60-65 million years ago and their light/visibility has only reached the location 60-65 million light years (or 382,102 trillion miles) away yet. [via quora]
9. The World’s population can fit comfortably in Texas
The world with a population of 7 billion can fit easily in Texas –Tweet this– (water included in area) with each person having a 1000 sq. foot property of his own. Of course, there’ll be no space for roads, parks and other infrastructure whatsoever. [image courtesy: aliveandyoung]
10. A day (sunrise to sunrise) on Mercury is 176 Earth days
Unlike earth, the planet Mercury rotates very slow about its own axis taking almost 59 of our days to complete one rotation. That’s one day by Mercury’s definition, however, one solar day (sunrise to sunrise) on Mercury, which depends on both its rotation and orbital motion around the sun, is 176 Earth days.
Mercury completes its orbit around the sun in approx 88 days so it’s daytime for one Mercurian year, and night-time for another Mercurian year. To complicated to understand? Watch the simple animation. You’ll notice that the Mercury completes its orbit around the sun during the time from its sunrise to sunset. And while the sun rises back from the sunset, it complete yet another orbit around the sun. So from sunrise to the next sunrise, Mercury orbits around the sun twice i.e. 176 days.
Tuvalu, a tiny island midway between Hawaii and Australia with a population of just 9,860, receives yearly payment of almost $4 million for literally doing nothing at all. The reason? This is the money that the Tuvalu government receives from royalties from the country’s domain name, .tv!
Before you all fire up your calculator, let me burst your bubble that the money comes down to just about $405 per person and also that this money goes to the Tuvalu’s government. Tuvalu commercialized its internet TLD, .tv, in 1988 and started receiving royalties which now account for almost 10% of the government’s total revenue.
Isn’t it amazing that a country that’s merely a speck in ocean (10 sq miles to be exact) with nothing but hundreds of miles of water around it controls something so crucial to the internet world?! [via: Neeharika Palaka on Quora ]
And you thought Fibonacci numbers is of no use?! A number is a Fibonacci series is (approximately) equivalent in kilometres to the previous number in miles allowing you to convert miles to kilometres and vice-versa in a ‘mathematical’ fashion.
In mathematics, a Fibonacci series is made up numbers that are sum of the previous two numbers starting with 0 and 1.
5 miles is 8 kilometres and 3 kilometres is 2 miles. Not only the Fibonacci series does the conversion for you, it also rounds off the result (except for the first two numbers in the series). For example 21 miles is exactly 33.7962 kilometres which rounds to 34 and similarly 144 kilometres is exactly 89.4775 in miles which rounds off to 89.
The Golden Ratio:
As we move towards higher numbers in Fibonacci series, the ratio of two consecutive numbers converges to 1.1618, also known as the golden ratio. The mile/kilometre ratio happens to be 1.6093 which is way close to this golden ratio hence can be used interchangeably if you’re not working on a space ship!
But what is 100 Kilometers in Miles?
The series is very sparse with only thirteen values within 200 range but you can still convert 100 miles in kilometers using nothing but the Fibonacci series itself. Here’s how:
100 = 89 + 8 + 3
We don’t have 100 in the series but we do have an 89, a 8 and a 3, ahah!
100km = 89km + 8km + 3km
100km = 55m + 5m + 2m
100 kilometers = 62 miles (the exact answer is 62.1371)
This makes Fibonacci one less thing from your list of ‘math I learned in college with no use in real life’ 🙂
Edit: Or you can just type “100 km in miles” in Google and get the answer back.
