1 Much to Bowlby's annoyance a similar letter to The Times was not published.
2 One could almost describe attachment as an ethological gravitational force.
3 “What Des-Cartes did was a good step. You have added much several ways, & especially in taking ye colours of thin plates into philosophical consideration. If I have seen further it is by standing on ye shoulders of Giants.” Newton to Hooke, 5th February, 1676. Kepler and Galileo were the scientists he is thought to be referring to.
4 Konrad Lorenz and Nikolaas Tinbergen shared the Nobel Prize in Physiology or Medicine with Karl von Frisch in 1973. Robert Hinde was elected a Fellow of the Royal Society the following year.
