The term 'bijective' is a fairly old one, the earliest reference I found in a Mathematical Reviews index was for 1939.. Anyone who has had a college course in mathematical logic or, yes, set theory is likely to know or have forgotten its meaning.
It does, however, have a bad reputation because of its use to intimidate non-mathematicians. The example in Quine's Quiddities under the topic mathematosis illustrates why. Still, it is perhaps better than 'roundtrip', which in ordinary use does not really imply bijective. My wife and I both found that we were measurably heavier after a recent Boston-Roma-Boston trip. Additional efforts were required to restore our status quo ante weights. --jg ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
