in 1993 Influenced by the documentary lesson of
Roberto Rossellini, in 1968 Angela produced a series of documentaries entitled "The Future in Space", on the theme of the Apollo program; during the filming carried out in the United States he also made numerous live connections for RAI on the occasion of the launch of the
Saturn V carrier which brought the first astronauts to the moon. The
Quark formula was at the time particularly innovative: all the technological means available and the resources of television communication were used to familiarise them with the topics covered: the BBC and David Attenborough documentaries, the Bruno Bozzetto cartoons used to explain the most difficult concepts, the interviews with the experts exposed in the clearest possible language compatible with the complexity of the topics, the explanations in the studio. From the basic programme, several spin-offs were born, some of which are still produced: naturalistic documentaries ('
and '), financial (
Quark economia), and politicians (
Quark Europa). In 1984 Angela produced
Pillole di Quark ('Quark's Pills'), a thirty-second spot on technical, scientific, educational, social, and medical topics, which was broadcast at variable times on Rai 1. In the same year, Angela created the first talk show for mixed entertainment for scientific dissemination: six first nights live from the
Foro Italico, with guests from the world of culture, science, entertainment and sport on stage to interact with the audience. In 1995
Quark was succeeded by ''
, lasting two hours instead of one. Starting from 2000, Angela and his son Alberto introduced Ulisse'', a monographic show dedicated to human history and discoveries.{{Cite web | url=https://biografieonline.it/biografia-piero-angela In 1986 and 1987 he conducted two prime-time shows on climate issues from the Turin Palazzetto dello Sport, in front of eight thousand spectators: atmosphere and oceans, followed by three television series that exploited new computer graphics: a journey inside the human body ('The Wonderful Machine'), in prehistory ('The Planet of the Dinosaurs'), and in space ('Journey in the Cosmos'). These series, created in collaboration with his son Alberto, were translated into English and sold in over forty European, American and Asian countries, including Arab and Chinese countries. In 1988 he was also involved in
Quark, a series of documentaries of nature, environment, exploration, and animal world produced and made by Italian authors, including Alberto Angela [his son] himself, who made some documentaries in Africa. In fact, in 1995
Superquark was born, during which, on 4 June 1999, two thousand episodes of the
Quark project and related subsidiaries were celebrated. That same year are also the ''
, monothematic evenings on subjects of great social, psychological and scientific interest, and the collaboration in the television programme Domenica in, in which Angela was the anchor of a space dedicated to culture. In 1997 Quark Atlante – Immagini dal Pianeta
was born from a Quark rib. Immagini dal Pianeta – RaiPlay
was born from a Quark'' rib. Finally, since 2000 Piero and Alberto Angela have been authors of Ulysses, a monographic instalment programme concerning historical and scientific discoveries. Parallel to the popularising activity on television, Angela has carried out publishing activities, always with information content. He has long been the editor of the
Scienza e società ('Science and Society') column in the weekly TV series
TV Sorrisi e Canzoni ('TV Smiles and Songs'). Angela was also the founder and supervisor of the monthly magazine
Quark, which he founded in 2001 and dissolved in 2006 due to lack of funds. The monthly magazine, inspired by the television programme dealt with scientific topics in a manner accessible to the public. Angela is also the author of over thirty books, many of them translated into English, German and Spanish, with a total circulation of over three million copies. ==Other activities==
