Thank you! Time Enough for Love was published in 1973, and this article is from 1963, so it doesn't count as a Heinlein invention: My stool was bolted to the deck, I had added a seat belt. As I strapped myself down, I reminded them that we had a rough ride coming-and this we had not been able to practice; it would have risked miscarriage. "Lock your fingers, Joe, but let her breathe. Comfortable, Llita?" "Uh-" she said breathlessly. "I-I'm starting another one!" "Bear down, dear!" I made sure my left foot was positioned for the gravistat control and watched her belly. Big one! As it peaked, I switched from one-quarter gravity up to two gravities almost in one motion-and Llita let out a yip and the baby squirted like a watermelon seed right into my hands. I dragged my foot back to allow the gravistat to put us back on low gee even as I made a nearly instantaoeous inspection of the brat. --- But more interesting is the Senior's allegation that he used a pseudogravity field in that year to facilitate childbirth. Was he the first tocologist to use this (now standard) method? Nowhere does he assert this, and the technique is usually associated with Dr. Virginius Briggs of Secundus Howard Clinic and a much later date. http://www.technovelgy.com/ct/content.asp?Bnum=1929 http://www.technovelgy.com/ct/content.asp?Bnum=1929
