30 is an important number for this engineer and every other engineer licensed in this state. It is the number of hours of continuing education each of us must take every two years, or, as they like to say, every biennium (which is two years), in order to retain one’s license.
Every licensed engineer knows this number for their state. Without it we could not don the title P.E., which comes with all kinds of rights and privileges granted thereof.
As numbers go, it is somewhat important, if only to make sure we are able to sign plans and attest that, yes, we’re pretty sure this thing won’t fall down.
