Наука і технічний прогрес

A famous microbiologist Rita Colwell:

    “Science is discovery. Science is fun. Science is understanding what makes a clock tick and what makes a cat purr, what makes the Sunrise and what makes the Moon look so large on the horizon…”

The motto:

“Necessity is the mother of invention.”

- How do you understand this proverb? (If someone really needs to do something, they will find a way of doing it)

- Nowadays we can even say that “Comfort is the mother of invention” because various inventions in electronics transport etc. make our life easier and more comfortable.
