Technological revolution. Axe made of iron, dating from Swedish Iron Age, found at Gotland, Sweden: the iron—as a new material—initiated a dramatic revolution in technology, economy, society, warfare and politics.
A technological revolution is a period in which one or more technologies is replaced by another technology in a short amount of time. It is an era of accelerated technological progress characterized by new innovations whose rapid application and diffusion cause an abrupt change in society. Description[edit] IBM Personal Computer XT in 1988—the PC was an invention that dramatically changed not only professional life, but personal life as well.
A technological revolution increases productivity and efficiency. What distinguishes a technological revolution from a random collection of technology systems and justifies conceptualizing it as a revolution are two basic features: 1. The consequences of a technological revolution are not necessarily positive. Sectoral (more technological changes in one sector, e.g. The 50 Greatest Breakthroughs Since the Wheel - James Fallows. Jump straight to the list Some questions you ask because you want the right answer.
Others are valuable because no answer is right; the payoff comes from the range of attempts. Seven years ago, The Atlantic surveyed a group of eminent historians to create a ranked list of the 100 people who had done the most to shape the character of modern America. The panelists agreed easily on the top few names—Lincoln, Washington, Jefferson, in that order—but then began diverging in intriguing ways that reflected not simply their own values but also the varied avenues toward influence in our country. Lewis and Clark, or Henry Ford? Now we turn to technology. One panelist ranked his choices not by importance but by date of invention, oldest (cement) to newest (GPS satellites).
In short, these scientists and creative types decided to answer the question they wanted us to ask, rather than the exact one we posed. History of invention: A science and technology timeline.

Inventions - Kids Discover. Make Tinker Trays. I started a new job last week.
I am the new atelierista (art teacher) at a Reggio based preschool close to where I live and I just love love love it! Reggio is a play based approach that I learned about several years ago and immediately fell in love with. There are several key elements to the Reggio approach to learning, which I will be sharing more and more about over time. Today, I want to focus on the idea of the environment as the teacher, a Reggio essential. In a Reggio classroom, the environment is carefully constructed and designed to engage active learners who are inspired to think, ponder and create. *This post contains affiliate links.

As always, all opinions are mine alone. We only share items that we love and use at home! My kids love to learn how things work! You will frequently find them taking things apart or weilding a screwdriver to help Dad with projects around the house. And yes, we have had our own share of mishaps as a result of their explorations -- but we've learned that those broken items are just a part of life when you're raising curious kids.
In order to give them the opportunity to 'tinker' and explore, we've offered the kids a variety of ways to get hands-on as they build, explore and create new inventions. One of their favorites is to have their own Tinker Box -- an activity that offers them the opportunity to use tools, learn how things work and engineer to their hearts content! 12 Movies That Will Inspire Kids to Tinker. This week's topic in our Summer Movie Series for Kids is all about inventions!
There are a number of wonderful films that will inspire children to tinker and create new things -- kids always come up with the most amazing ideas when given the chance ;) For example, my daughter wants a robot that will do all her chores (wouldn't we all love one of those!) In addition to some very creative inventions, these movies also offer a peek into the process of trial & error.
