简介:

  在地殼底下融融的岩漿高達攝氏6000度以上,岩漿的輻射作用,就像一股巨大的能量,造就了深海豐富奇妙的生物景觀。透過深海探測潛艇“愛文號”(Alvin)攜帶高科技的儀器、燈光和攝影技術,將三千多公尺下的神秘景觀,盡收在《深海火山》這部影片裡,同時活生生的呈現在我們的眼前。
  大西洋有一條中洋脊(Mid-Ocean Ridge),位於3500公尺的海面下,長度有6萬4千多公里,寬度有800公里。中洋脊的熱液噴口,噴湧出含有礦物質、金屬的熱水。在噴口的附近有將近240倍的大氣壓力,溫度的變化從攝氏2度到400度,在這不可能有生物存在的地方,卻發現了奇妙的動物以此為家。例如:在高溫且高毒性的硫化氫環境中,“愛文號”發現了類似拖把狀“龐貝蟲的環節動物”(Alvinella)在我們看來嚴峻的環境中來去自如。
  深海的火山系統,就像似烤箱的熱源,它將地殼及海水加熱,同時釋放出營養鹽(Nutrients)當作許多深海生物的食物來源。
  深邃漆黑的海底,就像浩瀚無窮的宇宙一般,吸引著我們人類的注意力。深海的景觀是如此神秘與奧妙,這不僅使科學家重新思考有關生命的課題,也促使我們對外太空有生命的存在抱有希望。

简介:

  A witty, exhilarating and mind-expanding exploration of the word of our times - data - with mathematician Dr Hannah Fry. Following in the footsteps of BBC Four's previous gleefully nerdy, award-winning maths films The Joy of Stats, Tails you Win - The Science of Chance and The Joy of Logic, this new high-tech romp reveals exactly what data is and how it is captured, stored, shared and made sense of. Fry also tells the story of the engineers of the data age, people most of us have never heard of despite the fact they brought about a technological and philosophical revolution.
  For Hannah Fry, the joy of data is all about spotting patterns. She's Lecturer in the Mathematics of Cities at UCL as well as being the presenter of the BBC series Trainspotting Live and City in the Sky, and she sees data as the essential bridge between two universes - the tangible, noisy, messy world that we see and experience, and the clean, ordered, elegant world of maths, where everything can be captured beautifully with equations.
  Along the way the film reveals the connection between Scrabble scores and online movie streaming, explains why a herd of Wiltshire dairy cows are wearing pedometers, and uncovers the remarkable network map of Wikipedia. What's the mystery link between 'marmalade' and 'One Direction'?
  The Joy of Data also hails the giant contribution of Claude Shannon, the American mathematician and electrical engineer who, in an attempt to solve the problem of noisy telephone lines, devised a way to digitise all information. It was Shannon, father of the 'bit', who singlehandedly launched the 'information age'. Meanwhile, the green lawns of Britain's National Physical Laboratory host a race between its young apprentices in order to demonstrate how and why data moves quickly and successfully around modern data networks. It's all thanks to the brilliant technique first invented there in the 1960s by Welshman Donald Davies - packet switching - without which there would be no internet as we know it.
  But what of the future, big data and artificial intelligence? Should we be worried by the pace of change, and what our own data could and should be used for? Ultimately, Fry concludes, data has empowered all of us. We must have machines at our side if we're to find patterns in the modern-day data deluge. But, Fry believes, regardless of AI and machine learning, it will always take us to find the meaning in them.
