Hi! I’m Danyl Goldberg, though in blogs I’m often known simply as Uncle Danya. For over 25 years I worked in IT and marketing — all this time I was learning to explain complex things in simple terms and bring order to tangled systems. I am not an academic professor, but simply an enthusiastic researcher. This book is the result of my reflections and an attempt to put together a clear, logical, and beautiful puzzle of how our Universe works, without unnecessary science for the sake of science.
