Dear Nikola, a) Thank you very much for your letter. b) I very much hope that you are happy, comfortable and well. c) I have read your layrinthine letter once in its entirety. Parts of it, I have read several times. d) ‘Well!’ ... ‘This beats everything! The skill with which this has all been designed is quite out of this world!’ e) As you know, I refrain from asking probing questions. I am prepared to listen to or to read whatever supplementary and explanatory information you wish to give me. f) I have been reading lecture notes by Philip Harris, a physics professor at the University of Sussex, about Special Relativity. I have also been reading Wikipedia explanations and summaries of General Relativity. I discover to my surprise and satisfaction that the phantasy-key which seems to unlock the Chinese garden labyrinth that you have pointed out to me, seems also to fit the lock of relativity physics. g) I acknowledge that I may be mistaken, and that in both instances, converning both the Chinese garden and relativity phydics,my presumption to understand may be an illusion. h) Stay well and happy.
