The Elements Revealed: An Interactive Periodic Table

In the October 2011 issue of Scientific American, we celebrate the International Year of Chemistry. Learn more about its impact on our daily lives in our Special Report. UPDATED: 06/18/2013 In honor of the 2013 Lindau meeting, which focuses on chemistry, we have updated our interactive periodic table with links to Nature Chemistry's In Your Element essay series. Each essay tells the story of a particular element, often describing its discovery, history and eventual uses.

Top Tech Trends of 2011 (infographic) Stay Connected with Us! Follow TechnoBuffalo So what can we learn from 2011? Well for one, according to this infographic, it seems people en masse absolutely do not like being hardwired. On the contrary, our affinity for sharing, streaming and being mobile has become a full-blown obsession.

Sleep musicalization - Perceive your sleep as a unique musical experience! Perceive your sleep as a unique musical experience! Sleep musicalization is a novel way of perceiving and experiencing sleep measurement data. The goal is to help users understand and analyze their sleeping patterns and eventually improve their sleep. Musicalization of data provides a whole new way to experience data as a music. The Earth and Beyond Welcome to The Earth and Beyond Hello, my name is Tim O'Brien. I'm an astronomer working at The University of Manchester's Jodrell Bank Observatory. As an astronomer my job is to try and understand how the universe works and my main interest is why some stars explode - more about this later! Abundance of the chemical elements For example, the abundance of oxygen in pure water can be measured in two ways: the mass fraction is about 89%, because that is the fraction of water's mass which is oxygen. However, the mole-fraction is 33.3333...% because only 1 atom of 3 in water, H2O, is oxygen. As another example, looking at the mass-fraction abundance of hydrogen and helium in both the Universe as a whole and in the atmospheres of gas-giant planets such as Jupiter, it is 74% for hydrogen and 23-25% for helium; while the (atomic) mole-fraction for hydrogen is 92%, and for helium is 8%, in these environments. Changing the given environment to Jupiter's outer atmosphere, where hydrogen is diatomic while helium is not, changes the molecular mole-fraction (fraction of total gas molecules), as well as the fraction of atmosphere by volume, of hydrogen to about 86%, and of helium to 13%.

We have even lamented that companies on both sides of the fence would rather spend time litigating than truly innovating and bringing new products to the table. It seems many people are sick of the patent system in the United States. The folks over at Frugal Dad have put together a nifty little infographic on the current state of the patent system in the United States.

Timeline of chemical element discoveries The discovery of the 118 elements known to exist today is presented here in chronological order. The elements are listed generally in the order in which each was first defined as the pure element, as the exact date of discovery of most elements cannot be accurately defined. Given is each element's name, atomic number, year of first report, name of the discoverer, and some notes related to the discovery. Table[edit] Frequently Asked Questions What is Edheads?

Metals That Enable Our Gadgets Are Vanishing It’s been widely reported that we’re running out of the rare-earth elements and various other metals that make our smartphones and computers run. But rarely do you get very precise information about how dire that problem is. It’s not that we don’t know--it’s simply that we haven’t had any decent information designers addressing the data. So having this nice little chart by Camden Asay is particularly useful: Given its clarity and concision, its no wonder that the chart actually won the $2,000 first-place prize in a contest run by David McCandless’s Information Is Beautiful. Of course, its very clarity makes you wonder about the data.
