Join 📚 Roger's Highlights
A batch of the best highlights from what roger's read, .
In any case, I want to conclude this book with the idea that has underpinned all of what you’ve just read. That it’s admirable to want to be better businessmen or businesswomen, better athletes, better conquerors. We should want to be better informed, better off financially . . . We should want, as I’ve said a few times in this book, to do great things. I know that I do. But no less impressive an accomplishment: being better people, being happier people, being balanced people, being content people, being humble and selfless people. Or better yet, all of these traits together. And what is most obvious but most ignored is that perfecting the personal regularly leads to success as a professional, but rarely the other way around. Working to refine our habitual thoughts, working to clamp down on destructive impulses, these are not simply the moral requirements of any decent person. They will make us more successful; they will help us navigate the treacherous waters that ambition will require us to travel. And they are also their own reward.
Ego Is the Enemy

The universe was expanding, swiftly and evenly in all directions. It didn't take a huge amount of imagination to read backwards from this and realize that it must therefore have started from some central point. Far from being the stable, fixed, eternal void that everyone had always assumed, this was a universe that had a beginning. It might therefore also have an end. The wonder, as Stephen Hawking has noted, is that no one had hit on the idea of the expanding universe before. A static universe, as should have been obvious to Newton and every thinking astronomer since, would collapse in upon itself. There was also the problem that if stars had been burning indefinitely in a static universe they'd have made the whole intolerably hot—certainly much too hot for the likes of us. An expanding universe resolved much of this at a stroke.

Because we can't see into the Earth, we have to use other techniques, which mostly involve reading waves as they travel through the interior. We also know a little bit about the mantle from what are known as kimberlite pipes, where diamonds are formed. What happens is that deep in the Earth there is an explosion that fires, in effect, a cannonball of magma to the surface at supersonic speeds. It is a totally random event. A kimberlite pipe could explode in your backyard as you read this. Because they come up from such depths—up to 120 miles down—kimberlite pipes bring up all kinds of things not normally found on or near the surface: a rock called peridotite, crystals of olivine, and—just occasionally, in about one pipe in a hundred—diamonds. Lots of carbon comes up with kimberlite ejecta, but most is vaporized or turns to graphite. Only occasionally does a hunk of it shoot up at just the right speed and cool down with the necessary swiftness to become a diamond. It was such a pipe that made Johannesburg the most productive diamond mining city in the world, but there may be others even bigger that we don't know about. Geologists know that somewhere in the vicinity of northeastern Indiana there is evidence of a pipe or group of pipes that may be truly colossal.
