There was no posting last week because of professional and personal travel. There will be another one this week, which will actually be a report on that travel. But more on that in a bit.
While there was no posting to the blog last week, a number of small changes have been taking place. I have been going through various postings, correcting silently a few typographical errors. I have also been adding Arabic numerals to the Roman numbers in each essay title, since most people are not familiar with the expression of higher numbers in that system.
