Every so often, I plan to write tutorials introducing some field. These will tend to run longer than an average post. They are designed to give the intelligent and well-educated scientist an entry into a field for which he or she is not already a specialist.
When working with graduate-student interns, I find myself presenting these types of tutorials constantly. Unfortunately, this type of material is very hard to find in the literature, because it covers material that is too well-known to the specialist, while sometimes being beyond what is available in textbooks. Thus, there tends to be an artificial barrier to entry into new fields.
