In this the fourth volume of his work on the noble gases of the Periodic Table, Jeremy Sherr introduces us to Krypton, building on understanding and insight gained from his study of Helium, Neon and Argon. The author believes that every row in the periodic table strives to be like its related noble gas, so by understanding each of the noble gases in depth, we can gain insight into their preceding series as well as the whole periodic table. With reference to Krypton, this book will therefore illuminate the minerals Potassium through to Bromine – Krypton’s related series of remedies.

With central themes of boredom and frustration at work – the feeling of tedious repetition in an uninspired monotonous cycle, the desire to ‘get off the treadmill’ with a longing for freedom or lost childhood fun, we might recognise a Krypton patient through their tendency to compensate with spiritual practices, born of an intellectual and not a heart connection to spirituality. A generalised tendency to an intellectual disposition and/or an over-analytical approach to life, might indicate a need for this remedy, alongside a clear affinity for riddles, numbers, codes, hieroglyphs, logic, maths puzzles, computer programming etc
The connection with everyone’s favourite superhero Superman is also illustrative – he is an alien from Krypton come to Earth to do good, which he does, but his emotional world and love life are not nearly as developed.

With plenty of really thought-provoking cases and a chapter differentiating Krypton from other remedies such as Potassium, Bromine, Neon and Cryptococcus, this is a wonderful and expansive read for any one interested in the periodic table and the noble gases.
