The current financial crisis is a serious situation because it affects the foundation of the banking system: trust.
In most cartoons, the image of a bank is that of a safe behind bars, protected by security guards. This concept represents the essence of a bank, a place you trust to keep your money. Trust is so important that in a bank, all decisions are based on the impact that the decisions will have on the bank’s reputation.
Many years ago, banks realized that they could lend money in return for an interest rate.

- Not understanding the nature of the Internet. Too often, design teams think of the Internet as a pushing media such as television or radio. Users’ behavior on the Internet is different than when they are reading books or newspapers, listening to the radio or watching television. For example, when browsing, users have goals and look for information. If they don’t find what they are looking for, they will leave the page after 8 to 12 seconds. Users scan web pages. They don’t read. If something looks like an ad, they will rapidly look someplace else.

I am currently reading the latest biography of Albert Einstein by Walter Isaacson. I then decided to download the original 1905 paper of Einstein on the special theory of relativity. I was very impressed to see how beautifully Einstein exposed his theory but at the same time, very shocked to realize how poor the teaching I received about this was.

A few years ago, I was in a group that got lost during a hiking trip. One member of the group said “I know the way out. We just have to turn right and walk in that direction for 10 minutes; we will see a little farmhouse and the road to civilization”. He was sure of himself. We followed his lead but after 15 minutes of walking, no sign of the little farmhouse. The group began questioning the direction. After a while, it became obvious that we were led in the wrong direction. This leader failed and the magnitude of his failure was greater because of the high degree of confidence he expressed.

Just back from SanFrancisco, I was trying to find an address in Montreal.
I had to slow down in order to read the street name. While slowing down, a car almost hit my back bumper! Hope it doesn’t sound familiar but I am sure it happens frequently. (more…)

“Whitman says: “Despite its controversial reputation, nuclear is efficient and reliable.” Yet since 1950 there have been 20 nuclear accidents. One was major (on Mar. 28, 1979, at the Three Mile Island nuclear reactor) and one catastrophic (on Apr. 26, 1986, at the Chernobyl nuclear power plant). How can we say a major nuclear accident will not happen again?
