Millenáris, Building 'B'

World-renowned Hungarian inventions

Science without man is only a mystery. Science is both vast and small, both mysterious and often quite ordinary. It is all around us, shaping our world, the fantastic common denominator of the different peoples of mankind.

quote “Discovery consists of seeing what everybody has seen and thinking what nobody else has thought.” Albert Szent-Győrgyi

Curious explorers who set foot on new lands, engineers who realised their ideas, scientists who delved into the mysteries of the universe. They showed the world what only they had seen before, or dreamed possible.

The exhibition presents exciting, ground-breaking inventions, twists and turns, miraculous coincidences, seemingly impossible ideas, and unexpected discoveries. Outstanding Hungarian scientists, without whom the world would be a different place today.

Scientific innovations turn our lives upside down, redefining and improving them. The discovery of vitamin C by Szent-Györgyi, Semmelweis’s breakthrough in the prevention of childbed fever, Katalin Karikó’s mRNA vaccine, Goldmark’s colour television, Neumann’s computer, Dennis Gabor’s hologram—all have transformed our world and our everyday lives.

But science is also a game: a source of joy and laughter. When we play with a Rubik’s cube, when we watch astronauts perform funny tricks in zero gravity or when computer games or elaborate games of chess entertain us.

Science is fun: fun, wondering at the new.

This is the experience that the Dreamers of Dreams 20 aims to offer its visitors, opening 20 years after the first exhibition, with an entirely new collection of exhibits.
