Electromagnetic spectrum The electromagnetic spectrum is the range of all possible frequencies of electromagnetic radiation. The "electromagnetic spectrum" of an object has a different meaning, and is instead the characteristic distribution of electromagnetic radiation emitted or absorbed by that particular object. Most parts of the electromagnetic spectrum are used in science for spectroscopic and other probing interactions, as ways to study and characterize matter. In addition, radiation from various parts of the spectrum has found many other uses for communications and manufacturing (see electromagnetic radiation for more applications).

Londoners Living Near Street Trees Get Prescribed Fewer Antidepressants By now you're probably familiar with at least some of the many psychological benefits of urban greenery. Parks, trees, and other forms of nature evidently possess the power to refresh tired minds and improve moods; they've also been associated with better mental health more broadly. This robust line of evidence suggests that city trees serve as leafy happiness ninjas, defending our brains against the stressors of urban life. All of which is necessary background to make the findings of a new report in the journal Landscape and Urban Planning more palatable: Londoners who live near more street trees get prescribed fewer antidepressants. The largely U.K.-based research team—which includes some of the field's leading scholars—report that this association held true even when controlling for other local variables like socioeconomic status.
The Visual Leap - About Visual Thinking >> Home • About Visual Thinking About Visual Thinking Visual thinking, also called visual learning, is a proven method of organizing ideas graphically - with concept maps, mind maps and webs. Scientifically based research demonstrates that visual learning techniques improve memory, organization, critical thinking and planning. Visual thinking is an intuitive and easy-to-learn strategy that works for many academic and professional projects. The more complex the task or idea, the more useful this approach can be. Identify a Lie with 6 Simple Questions post written by: Marc Chernoff Email We all fall victim to at least a few lies during the course of our lifetime. Some lies may be extremely troublesome to our personal wellbeing, while other “white lies” may be far more innocuous. Either way, a lie is meant to deceive. So how can we avoid falling victim to a lie in the future?
Backing up mindmapping Buzan Online has responded to criticism of a lack of academic studies showing the efficacy of mindmapping with a list of references on this page. None of the papers are linked to there, it's just a plain text list (Why Mr. Buzan? If you claim "The Proof is Here!" 37 Data-ish Blogs You might not know it, but there are actually a ton of data and visualization blogs out there. I'm a bit of a feed addict subscribing to just about anything with a chart or a mention of statistics on it (and naturally have to do some feed-cleaning every now and then). In a follow up to my short list last year, here are the data-ish blogs, some old and some new, that continue to post interesting stuff. Data and Statistics
Visual thinking school Visual thinking is a way to organize your thoughts and improve your ability to think and communicate. It’s a way to expand your range and capacity by going beyond the linear world of the written word, list and spreadsheet, and entering the non-linear world of complex spacial relationships, networks, maps and diagrams. It’s also about using tools — like pen and paper, index cards and software tools — to externalize your internal thinking processes, making them more clear, explicit and actionable. Why is visual thinking important? There’s more information at your fingertips than ever before, and yet people are overwhelmed by it.
The Key to Infographic Marketing: The Picture Superiority Effect In Ancient times, Cicero considered memory training to not just be a method, but a form of art. He felt strongly that training your memory was one of the most valuable things you could do to improve your capabilities as a speaker, and a citizen. Even in ancient times, Cicero knew that remembering images was superior to remembering text alone. People remember pictures better than words, especially over longer periods of time. This phenomenon as we know it today, is called the Picture Superiority Effect*. It refers to the notion that concepts that are learned by viewing pictures are more easily and frequently recalled than are concepts that are learned by reading their written word form counterparts.
How to become a data visualization ninja with 3 free tools for non-programmers We noticed many times between the lines of this blog how data visualization is in the hype and how this trend is growing and growing. That’s good news guys! It’s fun and it’s … success! But as more and more people join this wild bunch we have to take care of those who are not as skilled as we are yet. There are many people out there who love data visualization but they think they are out of this business because they are not able to code. I personally think that this is a problem and that we have to be as inclusive as we can.
Time on the Brain: How You Are Always Living In the Past, and Other Quirks of Perception I always knew we humans have a rather tenuous grip on the concept of time, but I never realized quite how tenuous it was until a couple of weeks ago, when I attended a conference on the nature of time organized by the Foundational Questions Institute. This meeting, even more than FQXi’s previous efforts, was a mashup of different disciplines: fundamental physics, philosophy, neuroscience, complexity theory. Crossing academic disciplines may be overrated, as physicist-blogger Sabine Hossenfelder has pointed out, but it sure is fun. Like Sabine, I spend my days thinking about planets, dark matter, black holes—they have become mundane to me.
Visualization-based data discovery tools Visualization-based data discovery tools may account for less than 5 % of the Business Intelligence (BI) Market, but they are fighting above their weight in terms of profile. In 2011, Gartner placed Visualisation at the peak of the BI Hype Cycle. Despite this indicating the category may lose some of its lustre , Gartner are still predicting a compound annual growth rate of 30% in each of next 5 years. If true, this means the category will increase in value from $427 to $1,606 million over the period, a growth rate 3 times that of the overall BI market. So what are Data Visualisation tools and how are they defined? According to Gartner, there are 3 common elements
