Welcome - The Flow of History World History Animation: Human Population Growth Over All of History Imagine that for every million people on Earth, there was a single dot on a map. In total, that would be about 7,600 dots – representing today’s global population of 7.6 billion. But, what if we went back in time, and watched those dots accumulate over human history? When and where do the first dots appear, and when does population growth ramp up to get to the billions of people that are alive today? The History of Population Growth Today’s animation comes from the American Museum of Natural History, and it shows over 200,000 years of population growth and the major events along the way. If you consider yourself on the more impatient side of things, we suggest starting at 1:50 which will zoom you to 400 AD – the time of India’s Golden Age. It took 200,000 years of human history to get to one billion people – and just 200 years to reach seven billion. Key Population Moments Agriculture The impact of farming cannot be emphasized enough. East vs. Bubonic Plague Post-Industrial Revolution Thank you!
Chronologie et évolution de la planète Terre - Du big bang à nos jours Le Big Bang Schéma du Big Bang Tout commence il y a 14.5 Ga (milliards d'années) avec le Big Bang, une explosion fulgurante qui donne naissance à notre univers. En l'espace de quelques instant toute la matière constituant notre univers est deversée. C'est à partir de toute cette matière, que vont se créer tous les objets qui composent notre univers, galaxies, étoiles, planètes, et bien entendu, le reste aussi, vous, moi et tout ce qui nous entoure ! Environ 10 Ga (Milliards d'années) plus tard, se forme notre système solaire et farandole de planètes, dont la Terre. Il y a 4.6 Ga, la terre est encore en ébullition, c'est une masse de magma, une mer de lave, bien entendu pas de vie. Il va falloir attendre encore quelques millions d'années pour quelle se solidifie. La vie... Stromatolites La "vie" apparaît vers -3.8 Ga (durant le Précambrien), de simples cellules d'organismes procaryotiques, les bactéries. De cette époque, jusqu'à -2 Ga ... il n'y a pas de trace d'évolution. Le rythme s'accélère
Annenberg Media Exhibits: Collapse Hundreds of years ago in what is now modern Honduras, Copán was a thriving civilization, a center of the cultural life of the Maya. Tens of thousands of people made their home in the Copán Valley. Yet despite its importance, Copán went into decline. Across the vast territory of the ancient Maya, other important sites were sharing a similar fate. Classic Maya civilization was collapsing. Why did this great civilization fall? can combine with external causes (such as war or natural disaster) to bring about a collapse. Join us as we explore the collapse of four ancient civilizations. Ready to get started? "Collapse" is inspired by programs from Out of the Past, a video series from Annenberg Media.
