If you don’t know what to do, and are always in the dark, living in a powder keg, and giving off sparks, it is entirely possible, as Bonnie Tyler so eloquently observed, that you may in fact be experiencing a total eclipse of the heart.
However, although in his recently published Eclipses; What Everyone Needs to Know, Prof. Frank Close presents a wide range of information about eclipses, from the collected facts and figures pertaining to them, to the celestial mechanics that cause them to occur, to their place in scientific as well as social history, there does not appear to be anything addressing the cardiovascular variety of them. (Perhaps that will be included in the second edition.)
In all seriousness though, Prof. Close is one of the world’s foremost authors on the subject of eclipses. I reviewed his Eclipse; Journey’s to the Dark Side of the Moon just prior to the 2017 North American solar eclipse, and found it to be a remarkably accessible as well as enthusiastic presentation of the subject, which gives every reason to think that this new work, following the highly effective editorial structure of Oxford University Press’ What Everyone Needs to Know series, will shine a wealth of illuminating information about these remarkable astronomical phenomena.
