    Total Solar Eclipse in North America – Path of Totality – NASA/SVS (2017)

    During the August 21, 2017 total solar eclipse, the Moon’s umbral shadow will traverse across the North American continent, from Oregon to South Carolina. Transition from west to east coast will last a little over 90 minutes. Along the path of totality, observers will see the Moon completely obscure the Sun for about two and a half minutes. The math used to calculate the trajectory of the eclipses to create maps such as the one featured here was worked out […]

  • Dingo of the Australia – Adam Geiger (2013)

    Dingo of the Australia – Adam Geiger (2013)

    Dingo (Canis lupus dingo) appears in the archaeological record of Australia at 4230 years before present. They ruled the continent as apex predators together with the now extinct Tasmanian tiger within the last few thousand years. Dingoes successfully colonized the continent spreading into diverse habitats including tropical rainforests, temperate Eucalyptus forests, mountainous highlands and grasslands. The only exception is the dry inhospitable central deserts. Dog domestication is the earliest among other animals going back to 40,000 years ago. The Dingo […]

  • The Central Dogma of Biology – Kazufumi Watanabe (2008)

    The Central Dogma of Biology – Kazufumi Watanabe (2008)

    Riken Omics Center from Japan presents a well-crafted animation that summarizes one of the most important subjects of biology since 1958. The central dogma is our first systematic approach in understanding nature of the information flow and manufacture of structures within a living cell. The viewer must be warned that the structures in this animation are artistic representations and in reality they look quite different from space ships. For example RNA Polymerase II is one of the most well-studied enzymes […]

  • The World’s Most Boring TV … and Why It’s Hilariously Addictive – Thomas Hellum – TED Talk (2014)

    The World’s Most Boring TV … and Why It’s Hilariously Addictive – Thomas Hellum – TED Talk (2014)

    The idea of “slow-TV” was there. For years live cameras have been showing bears hunt fish in rivers, birds nesting and rearing their chicks with viewers in the millions. A Discovery Channel series called “Earth Sunrise” recorded a full hour of realtime sunrise in spectacular locations from around the world. Recording of a total solar eclipse in Brazil and Turkey was quite a memorable event. Slow-TV concept is a paradigm invented by real-time nature observers. The Norwegian television producer Thomas […]

  • Chimpanzee – Alastair Fothergill and Mark Linfield (2012)

    Chimpanzee – Alastair Fothergill and Mark Linfield (2012)

    The Chimpanzee is a heavily anthropomorphosized docu-feature movie targeting young audiences. It was filmed on multiple locations including Taï National Park in southwestern Ivory Coast, Ngogo and Kibale national parks in Uganda and Gabon by two British nature filmmakers Alastair Fothergill and Mark Linfield. Martyn Colbeck was the person behind the camera. Tim Allen did the narration. Filmmakers stitched the footage recorded in these locations and consolidated into a single story creating a drama around an orphaned baby Chimpanzee they […]

  • Origins of Human Cumulative Culture – UCL (2017)

    Origins of Human Cumulative Culture – UCL (2017)

    Captain James Cook was fascinated by Polynesians’ ability to converse with each other. In Tahiti a high priest named Tupaia got on board and accompanied him along their voyage to Hawaii. Despite the fact that the two islands were separated by more than 2500 miles Tupaia was able to converse perfectly with Hawaiians. In order to maintain a common language these seemingly isolated islands must have been connected by frequent trans-oceanic voyages. Genetical and ecological theory dictates that connectivity is […]

  • A Tour of the Cryosphere – NASA Goddard Space Flight Center (2009)

    A Tour of the Cryosphere – NASA Goddard Space Flight Center (2009)

    The cryosphere covers parts of the Earth’s surface where water is found in the form of snow, sea ice, glaciers, permafrost, ice sheets, and icebergs. Ice and snow exist close to their melting point. Fluctuations in surface temperatures of our planet leads to frequent state changes in water from solid to liquid and back. Using satellite observations scientists monitor such changes in the global and regional climate. The Earth’s cryosphere shrink and expand on a yearly basis. The animation begins […]

  • Weekly Changes in Arctic Sea Ice Age During 1984 – 2016 – NASA/SVS (2017)

    Weekly Changes in Arctic Sea Ice Age During 1984 – 2016 – NASA/SVS (2017)

    NASA’s Scientific Visualization Studio (SVS) has produced an animation showing the sea ice dynamics in the Arctic. The diminishing ratio of multi-year sea ice is staggering. Human contribution to global warming is well documented. The response of the polar regions to heating especially in the Arctic is extremely fast. While scientists are rushing to predict future temperature and precipitation using exceedingly complex climate models, the behavior of the cryosphere is a curious one. We are already witnessing rather large glacial […]
