We ask the big questions and find the freshest, most original answers, provided by leading thinkers on science, philosophy, society and the arts.

The earliest speculations about communication with extraterrestrial intelligence (CETI) involved contact with the inhabitants of other bodies of our Solar System, either our Moon or other planets. Astronomical theories in the nineteenth century made plausible a belief in the prevalence of life on non-terrestrial worlds circling our Sun. When the focus turned to the possibility of communicating with the potential denizens of these worlds, their relative closeness to the Earth made it conceivable that signals could be detected through optical telescopes.

The populations of the developed countries are becoming older while computer use is affecting increasingly wide aspects of life. Thus it is increasingly important that interface designs make software accessible to older adults. However there is almost no research on what makes an interface usable for older adults. As a stopgap measure this paper reviews the findings on the effects of age on relevant abilities and uses this information to provide suggestions to consider when designing interfaces for older users. The paper concludes with indications of the needed research in the area of interface design for older users.

The printing press was the great innovation in early modern information technology, but economists have found no macroeconomic evidence of its impact. This paper exploits city-level data. Between 1500 and 1600, European cities where printing presses were established in the 1400s grew 60 percent faster than otherwise similar cities. Cities that adopted printing in the 1400s had no prior advantage and the association between adoption and subsequent growth was not due to printers choosing auspicious locations. These findings are supported by regressions that exploit distance from Mainz, Germany – the birth place of printing – as an instrument for adoption.
