Deep Time : A History of the Earth - Interactive Infographic
Life on the planet started astonishingly early. The first living organisms, in the current model of evolution, are thought to be Prokaryotes1. The oldest known fossilised prokaryotes have been dated to approximately 3.5 billion years ago, only 1 billion years after the formation of the Earth's crust. Eukaryotes2 are more advanced organisms with complex cell structures, each of which contains a nucleus. Around 1.1 billion years ago multicellular3 organisms are thought to have started to develop, most likely similar in form to plants such as green algae. 200 million years later true multicellularity had also evolved in animals similar in nature to today's sponges, which are organisms which can reassemble themselves. Animals4, in the most basic sense of the word, are considered to have evolved from Eukaryotes. The dominance of the Dinosaurs6 lasted for over 160 million years, from around 230 Ma, to their ultimate demise at the end of the Cretaceous 65 million years ago. Related:  Interactives

The above is an interactive infographic. We have also developed a complimentary poster that you can view here: Sizes of the Universe poster. If you're technically inclined, here's a look at the references we used to construct these infographics: Facts About The Universe. Introduction: This interactive infographic from Number Sleuth accurately illustrates the scale of over 100 items within the observable universe ranging from galaxies to insects, nebulae and stars to molecules and atoms. While other sites have tried to magnify the universe, no one else has done so with real photographs and 3D renderings. How To Use: Credits:

surviveonmars.portail-svt 100,000 Stars Study Guide | Free Online Study Guides For Most Popular Tests Listen to an Earthquake’s Eerie ‘Whale Songs’ Is it possible to “hear” an earthquake? Not the rumbling of the ground that results, but the earthquake itself. Even if you could, what’s the point of listening? About a dozen years ago, geophysicist Ben Holtzman and musician/sound designer Jason Candler set out to answer these questions, with a side goal of sharing their passion for earthquakes with the public. From the fruits of their research, the SeismoDome show was born. Holtzman and Candler co-produce the show—with Holtzman writing scientific content, creating sounds from seismic data, and working with collaborators to produce the visual elements, while Candler handles the sound engineering and design and helps with the writing and conception of the show. When asked what listening to earthquakes can contribute to our knowledge of them, Holtzman explains how our subconscious factors in: “Humans perceive an enormous amount of information about physical processes through sound; we do it all the time, mostly subconsciously,” he says.

Curiosity Cabinet Over the past 25 years I have accumulated a collection of various gizmos, devices, toys etc. which to me are excellent examples of scientific principles or things that you look at and you say "That's impossible!" except it's staring you in the face. In the hope that others may also find them interesting and with the help of two undergraduates, Jacy Lundberg and Omar Khan, we have created videos of many of the items in the collection. Jacy and Omar are currently seniors in the Boston College pre-medical program. In the olden days some people assembled what were known as curiosity cabinets.
