In Theory and Practice
Those who would like to examine a subject thoroughly or want to test what has been learned previously are well advised to attend a workshop. Professional staff attempts to communicate a certain subject in detail over a period of usually 3 hours. Registration in advance is required and a fee will be charged.
Talks for beginners are normally shorter and take place in smaller rooms so that the conditions for discussions and questions are more attractive and one can be more responsive to the audience.
