Noted in a book review of A New Map of Wonders, by Caspar Henderson, reviewed by Mary Halton, NewScientist (2 December 2017, paywall):
Henderson’s own sense of wonder at phenomena both natural and manufactured is pervasive, from marvelling at a murmuration of starlings to admiring advances in solar power. Wonder, we then conclude, is a very personal experience, while scientific fact is often presented as a very universal one.
