"You can bet your beryllium that just about every chemistry class in the world has a poster-sized periodic table on the wall, but there&amp;rsquo;s a lot more to the elements than just atomic numbers and symbols, especially when dealing with Yiying Lu&amp;#039;s periodic table. Lu has integrated QR codes into the periodic table to provide additional information for all the curious chemists out there. Each element on Lu&amp;rsquo;s periodic table has a QR code that smartphone users can quickly scan to link to a corresponding Wikipedia page where they can learn more about it. There are even supplementary QR codes that give details on the properties of each elemental group.  For example, did you know that the halogen group is the only group that contains elements in all three familiar states of matter (solid, liquid, gas) at standard room temperature and pressure? If not, you might want to check out Walls360.com to get your very own QR coded periodic table and start impressing everyone around you with your superior science knowledge."^^<http://www.w3.org/2001/XMLSchema#string>
