These are generally called beam splitters, as a beam of light is focused on the splitter part of the beam will carry on, on its original course while the other veers off at a ninety-degree angle.)

These mirrors are known as atomic mirrors. They use an electromagnetic field to reflect neutral atoms and are used to trap slow atoms or to focus an atomic beam.)

This distance changes because of the moon’s elliptical orbit around the Earth, so it is important that such a facility exists.)

Before the development of radar, mirrors were used in the second World War to detect sounds coming from enemy aircraft.)

This only changed in around 6000 BC when polished glass began to be used.)

Mirrors have been around for as long as 8,000 years ago. Silvered-glass mirrors first started almost 200 years ago. ]]> 2018-05-17 16:00:39 UTC https://padlet.com/i33246/uzcd48ovtnbf/wish/261643978 Where and how did it originate? i33246 https://padlet.com/i33246/uzcd48ovtnbf/wish/261645426 In 1835, a German chemist Justus von Liebig made a thin layer of metallic silver to one side of a pane clear glass. Later on it has been improved into a modern mirror we use today.]]> 2018-05-17 16:04:10 UTC https://padlet.com/i33246/uzcd48ovtnbf/wish/261645426 How has it or its use changed over time? i33246 https://padlet.com/i33246/uzcd48ovtnbf/wish/261645747 It didn’t it just get mounted and refined into different shapes and sizes. It also comes in different frames now. Mirrors are used for so many other things, such as laser reflectors to help amplify Ore cutting or cosmetic surgery.]]> 2018-05-17 16:05:01 UTC https://padlet.com/i33246/uzcd48ovtnbf/wish/261645747 How have different people used it? i33246 https://padlet.com/i33246/uzcd48ovtnbf/wish/261646475 The 7 categories mirrors were used in were Decorating, Safety, Vision, Magnification, Science, Energy, Affirmation Techniques, Photography, and Fashion Design]]> 2018-05-17 16:06:49 UTC https://padlet.com/i33246/uzcd48ovtnbf/wish/261646475 What were the major changes in its form or use (or how did it evolve)? i33246 https://padlet.com/i33246/uzcd48ovtnbf/wish/261646804 People used to look at their reflection by looking at water or in shiny polished metals. They could see themselves but not a clear glimpse of their full image. It wasn’t until high-quality image mirrors were found. Silver glass was invented when people could really see themselves. The first people that bought it were the wealthy people.]]> 2018-05-17 16:07:35 UTC https://padlet.com/i33246/uzcd48ovtnbf/wish/261646804 How “global” is your topic? How many different people and places does it impact? i33246 https://padlet.com/i33246/uzcd48ovtnbf/wish/261648028 Mirrors are definitely global, they are used by many different people have been using mirrors and they have used them in more than one way.  Mirrors have been used all over the world and a mirrors are at least used for at least 7 ways. The 7 different used are Decorating, Safety, Vision, Magnification and science, Energy and Affirmation Techniques, Photography, and Fashion Design. ]]> 2018-05-17 16:10:23 UTC https://padlet.com/i33246/uzcd48ovtnbf/wish/261648028 How does this object of study fit within the concept of thresholds of increasing complexity? k33201 https://padlet.com/i33246/uzcd48ovtnbf/wish/261652991 The mirror has remained in the thresholds of increasing complexity since the human image was discovered in clear water.  If the elements from the "Big Bang" didn't exist then the resources used to make a mirror would cease to exist.
