Online Highlights 4

I haven’t spent much time browsing the internet lately, but I’ve still managed to collect a few nice links to share with you (see other Online Highlights. Thanks to those who recommended these sites.

The Onion – It’s amazing that I haven’t noticed the onion before. It seems to be a well established phenomenon by now and one I’ve come to appreciate a lot. In short, it’s a news service focused on delivering sarcasm and humour instead of accurate news. Here are three of my favourites (please share yours!):Supreme Court: Death Penalty Is ‘Totally Badass’, Trekkies Bash New Star Trek Film As ‘Fun, Watchable’, Apple Introduces Revolutionary New Laptop With No Keyboard.

The Game of Miscommunication – A wonderful little game in which people alternately draw or write what the previous person drew or wrote.

Heavy Boots –  If you believe that astronauts were able to walk on the moon because they wore heavy boots, perhaps you should read this. And if you don’t think so, this will probably give you a good laugh, tainted with the sad reminder of how ignorant some people are who should know better.

Expats at work: Living abroad gives you an edge -This article in the Economist brings up a study on how living abroad affects creativity. Even though “creativity” is probably the wrong word here, “resourcefulness” or “creativity in problem solving2 would have been more suitable, the study is still interesting. If nothing else, it’s self-gratifying for people like me who live abroad.

Ball stunt – This is an amazing ball stunt of unknown origin. It’s rather short and it has to be watched, so I’ll leave you to it.

Title: A Brief History of Time
Author: Stephen Hawking
Year: 1988

This best-selling book by Stephen Hawking sets out to explain scientists view of the world, from ancient times to modern string theory, targeting non-scientists like myself. Even though I’ve begun to think that popular science books should be interesting and motivate more reading, A Brief History of Time was obviously not the right book to start with. I have mixed feelings about it: some parts (especially the beginning) I quite liked, but others not so much (the rest of the book). In short, the book poses some interesting questions, but quite fails to answer or discuss them in an entertaining way.

Let’s go through the book in chronological order. Hawking starts with describing our world view as it has developed from ancient times, explaining the various shifts in theories and societies aversion to change. This bit is interesting and should serve as a nice summary for people who either don’t remember what they learnt in school, but I don’t find much here I didn’t know already.

Gradually, the narrative changes to more modern views of the structure of the universe and the book becomes slightly more interesting for a while. I only took a limited amount of physics and maths in high school and it was at least six years ago, so even though I have some idea about what he’s talking about, it’s still nice to hear it again in a slightly different form. Up to this point, nobody should think it’s difficult to follow Hawking.

After this point, it becomes a lot more abstract though, with explanations of quantum mechanics, imaginary time and string theory. Here, I think Hawking at least partly fails and loses my halfway. Perhaps that’s because the subject matter is very hard, but spending a little bit more time on some arguments would have been a good idea, cancelling or leaving out something else to make the book more easily understood.

In addition to this, there’re some quirks I can’t really accept. This is supposed to be popular science, but Hawking repeatedly makes use of extremely large numbers without explanations (like saying that something would take a million million million million million years). If this is supposed to inspire some feeling about what we’re talking about, Hawking has failed. Large numbers have no meaning and he should know that. Leaving them out entirely or relating them to something would be the way to go here; lots of zeroes simply doesn’t impress. In addition to this, Hawking attempts to joke a few times, but almost always fails.

To wrap things up, I think this book might serve as a useful introduction to people who haven’t studied any of this before, but for me, it feels a bit like the first half is nothing new and in the second half Hawking isn’t that good at explaining what he’s talking about. Besides, Hawking’s style isn’t satisfactory; he tries to do a lot, but fails completely with some parts and succeed only partly with others. Perhaps the more recent A Briefer History of Time would have been more worthwhile, since it’s more succinct, but this books certainly is not.
