A public learning laboratory, The Exploratorium, is devoted to just that: exploring the world through science, art and human perception. Their mission is ‘to create inquiry-based experiences that transform learning worldwide’ and perhaps more importantly their vision is ‘a world where people think for themselves and can confidently ask questions, question answers, and understand the world around them’. The museum makes available a vast range of, video programmes, organised by subjects, including: Arts (532 videos), Astronomy and Space (220), Biology (331), Chemistry (97), History (35), Mathematics (19), Nature of Science (13), Perception (55), Physics (215), and Social Science (575). There is also a Websites section with over 35, 000 pages of content, which can be explored by subject too.
