I was 4-5. I was drawing these grand fountains and water works systems and my grandfather looked at one and saw that water was flowing uphill and explained in basic terms gravity and the Archimedes principle to me. After that I always wanted to be correct in my drawings so I got interested in children science books. My mom read me kids science stories/tales. I preferred them to fairy tales. I was 9. I remember imagining how it would be cool if instead of cells my body consisted of tiny robots that intermeshed together and substituted for various bodily functions. Sorta like nano bots I came to learn about 15 years after I was 10. it was 1988. Soviet Union. I kept drawing a small submarine with all the life support, buoyancy and structural elements I could think of. I wanted to swim from Chukotka/Kamchatka to Alaska
