... Active Skepsis . ... Probably, one should know the results from any actions. ... As a result, a sceptic, who discredits, for example, the tales of Christian wonders, has to follow the practical recommendations of Christianity or any other belief knowing how to act. ... As a result, scepticism restricts itself with discrediting secondary wonders, permanently replacing one doubtful interpretation with another and telling nothing of life and action. ...

... Сегодня: 10 апреля 2016 г. Не добившись успеха в поиске радиосигналов от инопланетных цивилизаций, ученые начали масштабный поиск оптических сигналов искусственного происхождения. 11 апреля 2006 года состоялось открытие нового телескопа в обсерватории Гарвардского университета. Это первый в мире оптический телескоп, разработанный специально для исследований в рамках проекта по поиску внеземных цивилизаций (Search for Extraterrestrial Intelligence, SETI). ...

We present a catalogue of galaxies for which spatially resolved data on their internal kinematics have been published; there is no apriori restriction regarding their morphological type. The catalogue lists the references to the articles where the data are published, as well as a coded description of these data: observed emission (E) or absorption (A) data, optical (O) or radio (R) data, velocity (V) or velocity dispersion (D), radial profile (1) or 2D field (2). ...
