Fractions, division of: One quarter is “one out of every four.” You are already doing division when you are doing fractions. To divide fractions (that is, to undo the division you are doing) turn it upside down and multiply.

Five Minute BA in Philosophy

That brilliant insight you read, heard or had: were you remarking about how you know (decide that, discover that or determine that) something or remarking about what it is (its nature)? Technically, is it an epistemological question or a metaphysical question (respectively)? More than likely, the insight is interesting only if you can confuse the two types of observations.

A Classical Education

Consider working on the seven liberal arts: the Trivium (grammar, rhetoric and logic) and the Quadrivium (geometry, arithmetic, music and astronomy)

An Undisciplined Education

The following questions do not seem to have an academic study or discipline that would address them:

  1. How are decisions made, when decisions are made well?
  2. How does work get done, when work gets done well?
  3. How do people work together, when people work together well?

The Problem of Questions

When giving a presentation, do you take questions during the presentation or hold them off until the end? If they are held off until the end, they probably won’t be asked. If they are given during the presentation, they interrupt its flow.

Have persons make a note of their questions, then break for questions every … fifteen minutes? There is probably an optimal interval to pause for questions. The written note to remind yourself of the question should be brief, perhaps three words. When you are writing, you are not listening.

A well prepared presentation should lead you along. The question you want to ask may be answered in the next few seconds. Waiting a hour before pausing for questions can make a brief note of three words unintelligible.

The compromise, then, would be to hold questions until a break, with frequent breaks.

Don’t be afraid to anticipate questions and, instead of waiting for the question to be asked, point out that further information is beyond the scope of this presentation.

The Problem of Mistakes

Don’t be afraid to make mistakes. That’s how you learn. But why do you have to learn so much?
