So now there are 118 . . . atomic elements that is. I just saw an article talking about four more elements (“Periodic table’s seventh row finally filled as four new elements are added“) being added to the periodic table. How chemistry, along with the rest of technology has changed. Reading over that article made me dig out my college chemistry text book. The periodic table at that time (early 1970s) only contained 103 elements. When I took chemistry in High School a few years earlier, there were even fewer.
So what does this mean? Knowledge is fluid and to maintain currency means life-long education. Whether that education is formal or informal, now, more than ever before, continuous learning is essential just to keep up. Fortunately the Internet has enabled many fine continuing education opportunities.
