Resumption of my blog: Justification for possible Readers

I started this resumption about Juneof 2018. I am aware of the need to justify myself, because of unfinished notes on the blog and a long break. The reason is simple, and basically two: my website was destroyed and the second reason is again the internet provider's fault, which changed CMS, so I lost a lot of content and I have to not only play it but also think about what is happening now and will happen in the future science. My modest reflections are shared on the blog, because I do not see the strength to write a book about so many different matters, sometimes ephemeral. I have a quiet hope that the guests of my blog will understand .
