A batch of the best highlights from what Hadar's read, .
On 15 September 1830, the first commercial railway line was opened, connecting Liverpool with Manchester. The trains moved under the same steam power that had previously pumped water and moved textile looms. A mere twenty years later, Britain had tens of thousands of miles of railway tracks.1 Henceforth, people became obsessed with the idea that machines and engines could be used to convert one type of energy into another. Any type of energy, anywhere in the world, might be harnessed to whatever need we had, if we could just invent the right machine. For example, when physicists realised that an immense amount of energy is stored within atoms, they immediately started thinking about how this energy could be released and used to make electricity, power submarines and annihilate cities. Six hundred years passed between the moment Chinese alchemists discovered gunpowder and the moment Turkish cannon pulverised the walls of Constantinople. Only forty years passed between the moment Einstein determined that any kind of mass could be converted into energy – that’s what E = mc2 means – and the moment atom bombs obliterated Hiroshima and Nagasaki and nuclear power stations mushroomed all over the globe.

By then I was sick of everything. I packed a bag and went to a Buddhist temple deep in the mountains somewhere in southern China. Oh, I didn’t go to become a monk. Too lazy for that. I just wanted to find a truly peaceful place to live for a while. The abbot there was my father’s old friend—very intellectual, but became a monk in his old age. The way my father told it, at his level, this was about the only way out. The abbot asked me to stay. I told him, “I want to find a peaceful, easy way to just muddle through the rest of my life.” The abbot said, “This place isn’t really peaceful. There are lots of tourists, and many pilgrims too. The truly peaceful can find peace in a bustling city. And to attain that state, you need to empty yourself.” I said, “I’m empty enough. Fame and fortune are nothing to me. Many of the monks in this temple are worldlier than me.” The abbot shook his head and said, “No, emptiness is not nothingness. Emptiness is a type of existence. You must use this existential emptiness to fill yourself.”

Over the last two centuries, the pace of change became so quick that the social order acquired a dynamic and malleable nature. It now exists in a state of permanent flux. When we speak of modern revolutions we tend to think of 1789 (the French Revolution), 1848 (the liberal revolutions) or 1917 (the Russian Revolution). But the fact is that, these days, every year is revolutionary.
