Following the Soviet-led invasion of Czechoslovakia back in 1968, the author of this study, just as thousands of other scientists and university lecturers in this country, was forced to leave his job at the Academy of Sciences and seek a new one. Needless to say, this was quite difficult because he was a member of a small group of university professors who had initiated a manifesto demanding protection of freedom and human rights, a document known as “Two Thousand Words.” For this reason, he was allowed to work solely “at the communal level.” He found such a job at the Design Institute for Transport and Engineering Structures, an institution that prepared its projects for the country’s capital city.
