English writer H.G. Wells once said that human history is often a race between education and catastrophe. Perhaps 'wisdom and folly' would be more befitting in this context. Every time folly outruns wisdom, catastrophe strikes. And every time wisdom gets the better of folly, great things happen. Take for instance, the curious case of September 4. The day has witnessed some remarkable events throughout history. While some of these were remarkable for all the wrong reasons, the day has not been without its merits. In instances where folly outran wisdom, ignoble incidents like the Peekskill Riots (1949), The Little Rock Crisis (1957) and the Golden Dragon Massacre (1977) happened. And in cases where wisdom managed to subdue the reptilian brain, things took a turn for the better. Indeed, it was on this very same day that Edison's light bulbs brightened up the New York City for the first time (1882), thus ushering in a sea change that would mark the birth of modern times. More than a century later, another great discovery would redefine our times, courtesy of two Stanford University graduates - yes, we are talking about Google here. Here is a comprehensive list of the good, bad and the ugly that September 4 bore witness to. For better or worse, these events most certainly did shape human history as we know it today.
