It is important that students of history explore tribal nuances. Within every continent, there is tremendous diversity. The tribal differences that caused the Apache and Navajo peoples to fight each other are not so different from the reasons Germans fought the French. Recognizing tribal diversity is an important step in understanding the history of America.

- Probability
If you want to take your understanding of probabilities to the next level, it's crucial to be familiar with the concept of a probability distribution. In short, a probability distribution is an assignment of probabilities or probability densities to all possible outcomes of a random variable.

- Loops
Most programming languages have the concept of loops: If we want to repeat a task twenty times, we don't want to have to type in the code twenty times, with maybe a slight change each time. As a result, we have for and while loops in the Bourne shell. This is somewhat fewer features than other languages, but nobody claimed that shell programming has the power of C.

- Understanding Regression
Whether undetected or wrongly explained, the phenomenon of regression is strange to the human mind. So strange, indeed, that it was first identified and understood two hundred years after the theory of gravitation or differential calculus. Furthermore, it took one of the best minds of nineteenth-century Britain to make sense of it, and that with great difficulty.

- When can we trust it?
Professional controversies bring out the worst in academics. Scientific journals occasionally publish exchanges, often beginning with someone's critique of another's research, followed by a reply and a rejoinder. I have always thought that these exchanges are a waster of time. Especially when the original critique is sharply worded, the reply and the rejoinder are often exercises in what I have called sarcasm for beginners and advanced sarcasm.

- Two selves
The possibility of conflicts between the remembering self and the interests of the experiencing self turned out to be a harder problem than I initially thought. In an early experiment, the cold-hand study, the combination of duration neglect and the peak-end rule led to choices that were manifestly absurd. Why would people willingly expose themselves to unnecessary pain?
