3 of us are Our co-workers at the intersection of magic and technology, so we're very honored to have you as a fellow but also as a magician at the story time. Thank you. As you already heard, my name is Marco Tempest, I'm a cyber-illusionist, which means I combine magic and technology to create something a little different. What you're about to see uses augmented reality, a layer of computer graphics superimposed over the real world. The magic happens up there on the screen and the real world is here. You can choose which to watch. The magic, the reality, or a little of each. So let's begin. Today is a special day, a day that we are all sharing, a day that will never be repeated, a day that we will all remember. Because of this, the calendar, 12 months, 365 days, sometimes a leap year. These days keep a record of our journey through time, past, present, and future. And we all think that one of these days is more special than the others. Our birthday, this is mine, December 13th. It was on my sixth birthday, that I saw my first magician. He produced a rabbit. A bird caught up raw. If you are a mystical disposition, you could say that this one day, this particular birthday, did indeed influence my future career. You'd be glad to know that I've known all over the house. That's been many attempts to correlate the date of our birth to our personality. And the most popular of these is astrology. Astrologers believe that our personalities can be ascribed to one of the twelve sunsines, patterns produced by the stars. So I'm not only born on December 13th, I'm also born on the star sign of the archery. Sagittarius. Ouch! Sorry. I read horoscopes for fun, but I don't take them very seriously. But then again, we Sagittarians are renowned for our skepticism. The Swiss psychiatrist Carl Jung took a different view. He was the founder of Analytical Psychology and profoundly interested with our connection with archetypes and symbols. We are born at a given moment in a given place and like vintage years of Rhyme, we have the qualities of the year and the season of which we are born. Astrology does not blame to anything more. Perhaps you shouldn't dismiss the astrologers too easily. Our own biological clocks depend on the movements of the planets. The sun after all rules our day. The light in the midst affects the brain which prevents the production of melatonin. The chemical that makes us feel sleepy. We have evolved the 24 hour body clock, that matches the rotation of our planet from day to night as it orbits itself. Hypocritus, the father of modern medicine meant further. He suggested that where and when you are born had an influence on your health and your life. Mayan said that summer babies have a house, your disposition which is a little disappointing for those of us born in the arm. Now I was born in the winter and the Swiss winter at that. Perhaps that's why it's my favorite time of the year. The calendar continues to guide our lives. It's the diary of our days. The sun of every hour we spend. We have it on our wall, computer and of course our watch. Now I have no idea whether the day of my birth by the party, my destiny. I leave that to the astrologers and the scientists to figure out. But I do subscribe to something that the theologian will embarkly said. He said that there are two great days in a person's life. The day you are born and the day you discover why. Now I hope that each and every one of you will discover you. Now one final say. There are 987 people in this room. According to mathematicians there is a 100% probability that you of them will share the same birthday and the 93.33% probability that one of these people will have their birthday today. Life this is you and you know who you are. Then I have only one thing to say. Happy birthday and happy birthday to the MIT Media Lab. Thank you. Thank you very much. Thank you.
