Ten Amazing Inventions From Ancient Times Dating back thousands of years are numerous examples of ancient technology that leave us awe-struck at the knowledge and wisdom held by people of our past. They were the result of incredible advances in engineering and innovation as new, powerful civilizations emerged and came to dominate the ancient world. These advances stimulated societies to adopt new ways of living and governance, as well as new ways of understanding their world. 1. Heron Alexandrinus, otherwise known as the Hero of Alexandria, was a 1st century Greek mathematician and engineer who is known as the first inventor of the steam engine. 2. The Nimrud lens is a 3,000-year-old piece of rock crystal, which was unearthed by Sir John Layard in 1850 at the Assyrian palace of Nimrud, in modern-day Iraq. 3. 4. 5. 2000-year-old metal coatings superior to today’s standards Read More Source: Ancient Origins

Livets utveckling En gång fanns ingenting, inget alls. Sedan kom en explosion. En Big bang och vårt universum skapades. Hur gick det till? Det är det ingen som vet. Det enda forskarna är överens om är att det skedde för över 13.5 miljarder år sedan och att universum har utvidgat sig och blivit allt större sedan dess. Efter big bang spreds materia och stoff ut i rymden. Jorden ursprung (4 600 000 000 år sedan) Man tror att jorden funnits i ungefär 4.6 miljarder år. Vattnet kommer Någon gång i jordens tidigaste historia tror man att planeten träffades av kometer. Det finns ett ordspråk som säger att "Samma vatten vi dricker nu fanns när dinosaurierna levde" eller någon liknande tidpunkt långt tillbaks i tiden.

Livets uppkomst (3 500 000 000 år sedan) Bakterierna De allra första levande cellerna var det vi kallar bakterier. När bakterierna utvecklades och blev allt mer komplicerade tappade en del av dem sitt klorofyll. Lummer

23 maps and charts on language by Dylan Matthews on April 15, 2015 "The limits of my language," the philosopher Ludwig Wittgenstein once posited, "mean the limits of my world." Explaining everything within the limits of the world is probably too ambitious a goal for a list like this. But here are 23 maps and charts that can hopefully illuminate small aspects of how we manage to communicate with one another. The basics Indo-European language rootsMinna Sundberg, a Finnish-Swedish comic artist, created this beautiful tree to illustrate both the relationships between European and central Asian languages generally, as well as a smaller but still striking point: Finnish has less in common with, say, Swedish than Persian or Hindi do. Language divides Bilingualism Who in Europe speaks EnglishMany countries have more than one commonly used language, with many residents learning two or more. English American English

Livets uppkomst och djurens evolution | Evolutionsteori.se av Johan Eklöf Detta är den gamla och tillika gratis, men icke omarbetade texten om djur, evolution och utveckling. Den är på flera sätt ok, men boken [Djurens evolution – en kort sammanfattning] är ändå att rekommendera, trevligare och bättre helt enkelt. Liv är förknippat med ämnes- och energiomsättning, fortplantning, tillväxt och förmåga att förnimma/registrera förhållanden i omgivningen (med öppna system som inte helt omfattas av termodynamikens lagar) samt med evolution – Nationalencyklopedin. Byggstenar Jorden och vårt solsystem bildades för ca. 4,6 miljarder år sedan. I avsaknad av nedbrytande organismer tilläts både aminosyror och nukleotider att spontant bilda långa kedjor av molekyler, bland annat primitiva DNA-strängar. Celler För att verkligt liv ska uppstå krävs det dock mer än bara självkopiering. Är vi utomjordingar? De flesta forskare anser att livet uppstod nära havsytan. De första bakterierna Enkelt räknat så finns det två typer av celler, prokaryota och eukaryota. Fiskar

Daniel Quinn: The Great Forgetting (Excerpted from the book, The Story of B) With every audience and every individual, I have to begin by making them see that the cultural self-awareness we inherit from our parents and pass on to our children is squarely and solidly built on a Great Forgetting that occurred in our culture worldwide during the formative millennia of our civilization. What happened during those formative millennia of our civilization? What happened was that Neolithic farming communes turned into villages, villages turned into towns, and towns were gathered into kingdoms. We can hardly be surprised that the forgetting took place. By the time anyone was ready to write the human story, the foundation events of our culture were ancient, ancient developments - but this didn’t make them unimaginable. In the absence of any other theory, it seemed reasonable (even inescapable) to suppose that the human race must have begun with a single human couple, an original man and woman. East and West Leavers and Takers Q.

Fossil Vill du veta hur lång tid det tar för ett fossil att bildas eller om alla fossila djur och växter är utdöda, finns svaren här. Du kan även läsa om fynd av fossil i Sverige. Spår av djur och växter Fossil är rester eller spår av djur och växter som bevarats i olika typer av sediment eller sedimentära bergarter som avlagrats någon gång under jordens historia. Fossil kan bevaras på en rad olika sätt beroende på omständigheterna, till exempel som försteningar eller avtryck. Hjälper oss förstå livets utveckling De mest kända och spektakulära fossilen är förstås dinosaurier, men det finns fossil av nästan alla typer av djur och växter. Vill du veta mer?

Human species 'may split in two' Humanity may split into two sub-species in 100,000 years' time as predicted by HG Wells, an expert has said. Evolutionary theorist Oliver Curry of the London School of Economics expects a genetic upper class and a dim-witted underclass to emerge. The human race would peak in the year 3000, he said - before a decline due to dependence on technology. People would become choosier about their sexual partners, causing humanity to divide into sub-species, he added. The descendants of the genetic upper class would be tall, slim, healthy, attractive, intelligent, and creative and a far cry from the "underclass" humans who would have evolved into dim-witted, ugly, squat goblin-like creatures. Race 'ironed out' But in the nearer future, humans will evolve in 1,000 years into giants between 6ft and 7ft tall, he predicts, while life-spans will have extended to 120 years, Dr Curry claims. However, Dr Curry warns, in 10,000 years time humans may have paid a genetic price for relying on technology.

Have You Heard of The Great Forgetting? It Happened 10,000 Years Ago & Completely Affects Your Life By Deep Ecology Hub / deep-ecology-hub.com/ Jan 23, 2014 This article summarizes the ideas of Daniel Quinn, first written about in The Story of B, which was a sequel to Ishmael. The longer, original essay can be read here, and comes highly recommended, especially if you find yourself disagreeing with the summary below. Most disagreements we've read about have turned out to be misunderstandings, so please check the original before coming to conclusions. The Great Forgetting refers to the wealth of knowledge that our culture lost when we adopted our new civilized lifestyle. The Great Forgetting accounts for an enormous cultural collapse as once tribal people found themselves in a new and strange mass centralized society. It is only recently that the Great Forgetting has been exposed. How The Great Forgetting Took Place It began around 10,000 years ago when one culture in the Near East adopted a new way of life that humans had not tried before.

This Is Roughly 200 Years Of American History In One Mesmerizing GIF There's a ton of juicy stuff in this incredible map. Couple of takeaways for me: 1. How about that neutral territory between Oklahoma and Texas that went away around 1890? 2. What caught your eye about this map, Internet?

Clarification: This map takes on history from the lens of how America became 50 states.

Absolute Time, Relative Experience | Who is the Man with the Name that Rhymes? It's been a while since another post. There are many topics that I have cached that I'd like to write on. If it weren't for the troubling aspect of so many things eating at my free time, you'd see more posts on here. I'm not sure there are many readers on here anyway, I've notice the traffic has slowed down to very little these days. Lately, an intriguing concept for me has been time. In physics, time is a duration between 2 events or physical states. Psychologically, however, time is a different creature. The brain isn't like a clock. The easiest way to explain temporal resolution is to compare to something like a video camera. But the brain isn't like a video camera either. So how does that relate back to feeling of time perception? To explain how this relates, I'll use the most common influence that everyone has first experience with: aging. Compare that to the last day of high school. Visually, I like to think of it as a day divided up into different memories of that day.
