Quantum mechanics 101: Demystifying tough physics in 4 easy lessons

Quantum mechanics 101: Demystifying tough physics in 4 easy lessons
Ready to level up your working knowledge of quantum mechanics? Check out these four TED-Ed Lessons written by Chad Orzel, Associate Professor in the Department of Physics and Astronomy at Union College and author of How to Teach Quantum Physics to Your Dog. 1. Particles and waves: The central mystery of quantum mechanics One of the most amazing facts in physics is that everything in the universe, from light to electrons to atoms, behaves like both a particle and a wave at the same time. But how did physicists arrive at this mind-boggling conclusion? 2. Austrian physicist Erwin Schrödinger, one of the founders of quantum mechanics, posed this famous question: If you put a cat in a sealed box with a device that has a 50% chance of killing the cat in the next hour, what will be the state of the cat when that time is up? 3. When you think about Einstein and physics, E=mc^2 is probably the first thing that comes to mind. 4. Related:  ciencia

System Innovation for Sustainability: Using Systems Thinking and Design Thinking | systeminnovationforsustainability I recently attended a webinar on using systems thinking and design thinking conjointly to address sustainability challenges. The webinar was presented by Peter Coughlan of IDEO and Colleen Ponto of Seattle University. It was great to hear from these forefront thinkers/doers thoughts similar to mine on the potential of using systems thinking and design thinking conjointly. 1. Sustainability is a system property. Figure 1. Sustainability science has complex adaptive systems theory as its main tenet, focuses on the dynamic interactions between nature and society and aims to bridge the natural and social sciences for seeking creative solutions to these complex challenges. Although there is a lot of discussion on sustainability within the design and innovation field and there are a lot of claims on sustainability of particular products/services/technologies or business operations/models/processes, I do not observe much of this being based on the science of sustainability. 2.

index Australopithecus deyiremeda is the name of the new fossil hominid species discovered in the site of Woranso-Mille —in the central region of Afar, in Ethiopia. The discovery, described in the international scientific journal Nature, takes to another level the on-going debate on early hominid origin and evolution in Africa. The scientific team lead by Professor Haile-Selassie has found several fossil remains (upper and lower jaws and a collection of teeth) in the sites of Burtele and Wayteleyta, in Woranso-Mille, in the central region of Afar, about 50 kilometres north of Hadar and 520 kilometres northeast of the capital Addis Ababa. Experts have assigned these 3.3 – 3.5 million-year-old fossil specimens to the new species Australopithecus deyiremeda. Lucy was not the only australopithecus in the Afar region Map of Ethiopia showing the Afar Region. Scientists have long argued that A. afarensis was the only pre-human species which lived in the region between 3 and 4 million years ago.

Thich Nhat Hanh Dharma Talks - Recent talks given by Thay from around the world. Getting Started with LabVIEW Interface for Arduino [LabVIEW Hacker] LIFA has been replaced with LINX. All new users should start with LINX and all current LIFA users should migrate to LINX. The LabVIEW Interface for Arduino (LIFA) allows users to control sensors and acquire data through an Arduino microcontroller using the graphical programming environment LabVIEW. Prerequisites Hardware Software Procedure Summary This getting started guide described the process of setting up the hardware and software to use the LabVIEW Interface for Arduino. Suggested Reading 4 Practical Philosophies That Will Empower You Philosophy is a fascinating branch of wisdom. However these esoteric ideas are sometimes difficult to translate into practical application. What are all of those thoughts, suppositions and theories actually good for? How can an understanding of philosophy ultimately help you lead a better life? Today I want to examine with you four philosophical ideas that have influenced my life in a very positive way. 1) Friedrich Nietzsche – Eternal Recurrence The Idea Several times throughout his works, Nietzsche talks about the thought experiment of eternal recurrence. Does the idea of eternal recurrence – that every moment of your life will repeat itself into eternity – leave you shivering with fear or with joy; whether you are living life fully everyday or just waiting for better times to come. Heaven or hell, you decide Let’s also assume that the life you are currently living is not simply one of the repetitions but is actually your first time around. 2) Socrates – No One Does Wrong Willingly L’idée

The Science of “Enlivenment” and the Commons One of the more provocative talks at the Economics and the Commons Conference last week was Andreas Weber’s critique of the “bio-economics” narrative that blends social Darwinism and free market economics. Bioeconomics is the default worldview for contemporary economic thought, public policy and politics. The only problem is that, by the lights of the latest biological sciences, this narrative is wrong, seriously wrong. Worse, it is impeding the emergence of a more accurate account of natural systems and life itself. It is thwarting our ability to develop a new, more respectful relationship with nature. Weber proposes instead a new story of “enlivenment” that points to a different vision of the "more than human world" and to commons-based based ways of organizing our political economy. Weber’s essay “Enlivenment: Towards a Fundamental Shift in the Concepts of Nature, Culture and Politics,” was just published by the Heinrich Boell Foundation.

History El hallazgo podría sentar las primeras pruebas sobre la existencia de 'físicas exóticas', absolutamente desconocidas para la ciencia actual. Un equipo internacional de astrónomos descubrió un 'súper-vacío' de 1.800 millones de años luz de diámetro, mientras se encontraba estudiando un área gigantesca del espacio, demasiado fría y raramente vacía. Esta región está situada relativamente cerca de nutro sistema solar, a unos 3 mil millones de años luz y, según el científico István Szapudi, a la cabeza del equipo, "se trata de la mayor estructura individual jamás identificada por la humanidad". Este 'punto frío' fue descubierto en la zona de 'súper-vacío', hace unos 10 años. El hallazgo, por entonces, asombró a la comunidad científica, dado que la aceptada teoría del Big Bang no prevé zonas frías de semejantes dimensiones. Fuente: The Guardian Imagen: NASA
