I haven’t posted anything about communication, so it’s really overdue – if your students are going to change the world they must be good speakers and communicators. I’ve met too many students with great ideas that never go anywhere because they couldn’t convince other people it was a good idea.
It’s especially important in the sciences and engineering, where there is an assumption that being correct is enough. Alas, it isn’t – you have to help others understand why it’s correct. Many good ideas have been missed, and terrible things have failed to be averted, because the people who were right weren’t able to clearly communicate the important information.
