• "...a beautifully executed lesson on the history of the universe" - The New York Times • Winner of the WSA Mobile Award • Top1 iPhone Book App in 10 Countries • Featured by The New York Times (Top10 iPad Apps of the year) • Featured by the American Photo Magazine (Top 10 Photo eBooks of the year) For iPad download - Back in Time Back in Time will take you on a stunning exploration of the history of our Universe, Earth, Life and Civilization. A journey through time where each event is documented with social and historical context, several images, an illustrative timeline and little-known interesting facts. Custom made animations bring those events to life, creating an interesting, immersive learning experience. An imaginary clock will guide you through this quest, proposing a simple analogy: the entire Universe started 24 hours ago. The Big Bang, the source of time and space, is the first event in our journey – the clock reads 0:00 hours. Today, 13.7 billion years later, the clock reads midnight. In between is a sequence of key events that has brought us to where we are today. Explore them, place them in perspective, see how they relate and understand the connections. We invite you to take a step back and see the whole picture. :::: REVIEWS - iPad version :::: "The coolest history textbook you’ll find on the iPad" - Bob Tedeschi, The New York Times “The iPad could use more apps like this one.” - The Daily “...a beautifully executed lesson on the history of the universe and the evolution of life on earth.
