Ask Me About Microscope & Magnification…
ASK ME ABOUT MICROSCOPE & MAGNIFICATION… Today, an instructor from The Discovery Museums in Acton visited my classroom and led a hands-on program about microscopes and magnification. Ask me to tell you what amazing things I observed looking through lenses! I can tell you how I used water as a magnifier and we can explore together by trying the water lens activity below. I also really enjoyed using the 30x handheld microscopes. Ask me to tell you about all of the objects we checked out in our classroom such as the carpet, my desk surface, my hair and my skin. The hand held microscopes are sold at The Museums’ gift shop, science stores and some electronic shops. WATER SCOPE The first magnifiers were made with water lenses. Try making you own water lens. You will need: Small or large plastic yogurt containers, plastic wrap, pair of scissors, water, large rubber bands What to do: 1.) Ask an adult to cut the bottom of the yogurt container off, leaving at least a 3 inch wide ring. 2.) Cut a piece of plastic wrap and stretch it over the mouth of the yogurt container. Secure it with a rubber band. 3.) Push down gently on the top of the plastic wrap to make a shallow well. 4.) Pour a little water into this well. 5.) Place objects under the container and look through the water at the object. What do you notice? 6.) What happens if you change the amount of water you are looking through? Take it to the next step: Experiment with making additional water scopes. -

Second Machine Age Or Fifth Technological Revolution? Different
Second Machine Age or Fifth Technological Revolution? Different interpretations lead to different recommendations – Reflections on Erik Brynjolfsson and Andrew McAfee’s book The Second Machine Age (2014). Part 1 Introduction: the pitfalls of historical periodization Carlota Perez January 2017 Blog post: http://beyondthetechrevolution.com/blog/second-machine-age-or-fifth-technological- revolution/ This is the first instalment in a series of posts (and a Working Paper in progress) that reflect on aspects of Erik Brynjolfsson and Andrew McAfee’s influential book, The Second Machine Age (2014), in order to examine how different historical understandings of technological revolutions can influence policy recommendations in the present. Over the next few weeks, we will discuss the various criteria used for identifying a technological revolution, the nature of the current moment, and the different implications that stem from taking either the ‘machine ages’ or my ‘great surges’ point of view. We will look at what we see as the virtues and limits of Brynjolfsson and McAfee’s policy proposals, and why implementing policies appropriate to the stage of development of any technological revolution have been crucial to unleashing ‘Golden Ages’ in the past. 1 Introduction: the pitfalls of historical periodization Information technology has been such an obvious disrupter and game changer across our societies and economies that the past few years have seen a great revival of the notion of ‘technological revolutions’. Preparing for the next industrial revolution was the theme of the World Economic Forum at Davos in 2016; the European Union (EU) has strategies in place to cope with the changes that the current ‘revolution’ is bringing. -

Mechanical Properties of Acrylonitrile Butadiene Styrene Thermoplastic Polymer Matrix with Carbon Nanotubes
Oct 14th – 16th 2015, Brno, Czech Republic, EU MECHANICAL PROPERTIES OF ACRYLONITRILE BUTADIENE STYRENE THERMOPLASTIC POLYMER MATRIX WITH CARBON NANOTUBES Jan VÁCHA1, Martin BORŮVKA1 1Technical university of Liberec, Studentská 2, Liberec 1, 461 17, [email protected], [email protected] Abstract This paper examines the mechanical properties of the composite of thermoplastic polymer matrix with carbon nanotubes. As the basic polymer matrix was used acrylonitrile butadiene styrene (ABS) to which were added the nanoparticles in a given percentage by weight in the form of nanotubes. Composite was injected into the Arburg injection molding machine. For evaluation were measured harness, impact and tensile test. These tests are compared with polymeric materials without added nanofiller. In conclusion is evaluated and compared influence on the mechanical properties of polymer matrix with carbon nanotubes and without fillers. Keywords carbon nanotubes, nanocomposites, mechanical properties 1. INTRODUCTION In the past ten years, extensive research and development have been carried out in the field of polymer composite production. On an industrial scale, melt processing has become the method of choice to incorporate color pigments or fillers. Nowadays, a wide variety of melt compounding technology is available which is applicable to polymer-CNT composite production [1]. Carbon nanotubes have a many properties (mechanical and physical) that make them attractive for use in a broad spectrum of applications, especially as filler for nanocomposites. There are two kinds of carbon nanotubes: single-walled carbon nanotubes (SWCNTs) with one graphene layer and multi-walled carbon nanotubes (MWCNTs) with many graphene layers wrapped onto themselves, see fig. 1. They can be produced in various ways such as chemical vapour deposition (CVD) laser ablation, arc discharge, solar energy and molten salt electrolysis.
