I've never met someone who is Russian - I am honoured to know you and to exchange 'chats' with you especially as I find maths (though utterly and truthfully captivating) my weakest point.
But I am an all time learner and enjoy reading about what fascinates other people. As passionate as I am about WORDS so I am able to read with wonder and awe about the work you do in the field of 'data plumbing'.
Plumbing is an excellent metaphor and has my mind working overtime imagining leaking water and such all over the place. A messy complicated job I'm sure.
My Johannesburg daughter and her husband have a business in the IT world and I am amazed by the language they talk regarding their work that is as foreign to me as Russian is.

The logo for my Word blog was drawn up by me BUT when I photographed it it came onto my blog upside down! I tried my limited tricks but couldn't win!
I used the 'word hand' taken from Pixabay.
I will have to rethink.
Give me something to chew on as I take my daily walk on the beach!
