190 activities Unit 1, exercise 28b Interviewer: If you detect an alien signal, or even a specific message, what then? Jill Tarter: If we detect a signal, we’ll do everything that we can at this site to make sure that it isn’t our own technology that’s fooling us or that it isn’t a deliberate hoax. One of the things that we’ll do to rule out a hoax is to call up another telescope and try to get an independent confirmation. Once we’ve informed the astronomical community, we’ll tell the world. We’ll tell the world because a signal isn’t being sent to us in California – it’s being sent to the planet Earth, and the planet Earth deserves to know about it. Interviewer: If you got a signal, would you send a reply? Jill Tarter: That’s a big question. Should we reply and if so, who’s going to speak for Earth? What would we say? That’s not a decision for me. So, most of the people that are working on SETI have agreed that if we receive a signal, we won’t transmit back until there’s some global consensus about these questions – because some people have a fear of the unknown, the different, and would not want to transmit, while many other people would say, “Yes, we should transmit, and you should tell my story, or describe my religion, or my view of the world, or my country.” So there’s a lot to be discussed. Interviewer: Do you really think the world could reach an agreement on what to do? Jill Tarter: Well, Freeman Dyson, the physicist, every time he hears me say this, he just laughs and says, “Jill, if you ever announce that you’ve detected a signal, and say where it’s coming from, anyone with a transmitter is going to shout whatever they want! And wouldn’t that be just about the best characterisation of twenty-first century Earth?” Unit 2, exercise 9 1 A woman takes paper from the office for her kids to use at home. 2 A man withdraws $100 from a cash machine but $200 come out.

The regions with the largest total GDPs were Eastern Asia and Southern Asia. These were also the most populous regions at that time. The regions with the lowest GDP in 1500 were central and south-east Africa. These regions also had the lowest GDP per person. The world’s wealth in the year 1500 “Slaves captured in raids and war grew in importance as a commodity. Kola nuts were also important, as were the dyestuffs of northern Nigeria. All these goods were highly prized in and around the Mediterranean basin.” (Richard Effland, 2003) Nur zu Prüfzwecken – Eigentum des Verlags öbv
