Dubai. The UAE. The posterchild of how a country can continue to be rich, even when the oil runs out. The story behind that is interesting, as I learnt as I read this (brief) history of Dubai by Tomas Pueyo. ( Note : Through this blog, Dubai means the entire emirate by the same name, not just the one city named Dubai).   The founder of Dubai, Sheikh Rashid bin Saeed Al Maktoum, feared this: “ My grandfather rode a camel; my father rode a camel. I ride a Mercedes. My son rides a Land Rover, and my grandson will ride a Land Rover. But his son will ride a camel.” Al Maktoum wanted to avoid that last line. And boy, has he succeeded: “Today, Dubai is not only a bustling city. It’s one of the most dynamic city-states on Earth.”   From ancient times, Dubai lay on/close to the trade routes (Mesopotamia to Persia and China; Mesopotamia to India and South East Asia). But that never helped! Dubai, after all, was just a desert, so nobody stopped there, nothing got traded...

When the West found oil in Persia/Iran, the Saudis started looking too and found it in 1938, writes Tomas Pueyo. They have the world’s largest onshore and offshore oil fields. Its oil is cheaper because it is nearer the surface, easy to access, and it spurts up easily. Oil today accounts for 80% of government income. That is scary and we will get to why that is the case.   The Saudis spend a bigger share of their income on the military than the US, Russia and Iran! Why spend so much? Partly the Shia and Iran threat, obviously. “Part of it is because the government has no legitimacy beyond that of the sword and religious radicalism, so it must make sure people are not scheming against it. This requires a big security apparatus.” And also, it creates many jobs in and related to the military, but again controllable by the government. And lastly, its location has too many choke points: the Suez Canal, the narrow strait from the Red Sea to the Indian Ocean, and the Straits of Hormuz. S...

At the end of Through the Language Glass , Guy Deutscher points out that colour, like beauty, lies in the eye of the beholder. As is well known, the eye has rods and cones. Colour perception is because of the cones. In humans, we have 3 different types of cones which can detect 3 separate colours – red, blue and green (RGB). Only those three, nothing else. How then do we “see” so many other colours?   Well, if light happens to activate both red and green cones with equal intensity, it gets interpreted as yellow. Put differently, we are not capable of detecting if a light is “truly” yellow or just a combo of equal intensity red and green! So all those non-RGB colours we are able to see? It’s just a combo of those three colours we can detect (RGB) combined in different intensities (ratios).   In fact, colour TV’s use just this point. They (like our eye) only support 3 different colours (RGB). By varying the intensities of those three colours at each pixel on the screen, ...

Tomas Pueyo wrote a great post on Saudi Arabia, informative on so many fronts. “Saudi Arabia is the biggest country in the world with no rivers! It only has wadis, ephemeral river beds that only occasionally carry water after rain.” Sure, everyone knows about the sand and desert , but did you know: “ The sand is so sandy that there are dunes up to 250 m high!” It is also rocky and mountainous on one side. Did you know the mountains are so tall that it even snows there?   From the above pic, you’d also notice the country is next to two major sea routes – the Red Sea on the left (west) and the Persian Gulf on the top (north). The coastal areas have also been on the trade routes with the corresponding opportunities for enrichment. Which is why you find so many different countries along those coasts:   Based on all this, you’d expect only the coastal areas to be the well-known cities of Saudi Arabia. And yes, Mecca, Medina and Jeddah lie close to the coast. But not the capital, ...

How does one check whether language reflects reality? Or if it is a lens that affects what we perceive and register? At this point, Europeans realized none of their languages could help answer the question – they were too similar, and had intermixed too much. So they began to pay attention to the languages of far off places, including the so-called “primitives”, writes Guy Deutscher in Through the Language Glass . “The deficiencies that Gladstone and Geiger had uncovered were replicated exactly in living languages all over the world… (for example) red was always the first of the prismatic colours to receive a name.”   On the other hand, the eyesight data contradicted the idea of “defective colour vision” – no tribe was found that couldn’t make out the difference among colours. What had seemed impossible was now a reality – even if people could notice a difference, they didn’t always bother to assign it a word.   Magnus now tweaked his theory. Agreed, he said, everyo...

As I read the chapter on Greece in Tim Marshall’s Power of Geography , I was surprised by how little I knew of the country’s history, beyond the usual Athens-democracy-Plato-Aristotle-Alexander parts! “Mountains and water are the key to understanding the past, present and future of Greece.” Greece has lots of mountains all over its north. From ancient times to present day, they made trade in the northward direction very hard. It also meant that people couldn’t move around easily and mix, leading to the lack of any unified identity. With the land/mountain route severely constrained, Greece turned to the only available option – the sea. The Aegean Sea. More on that later. The mountainous terrain meant no invader could control all of Greece – from Rome to Persia to the Ottomans to the Balkan states to the British. But the strategic value of control of the Aegean Sea meant all those empires would vie for rule over Greece. Greece, thus, was never an independent nation, even as recentl...
