Skepticism has a place, but it's optimists who decide the future, says Kevin Kelly.
The news certainly doesn't portray it this way, but every year the world becomes a better place, says Kevin Kelly. There is currently an imbalance in our optimism and pessimism levels, because we feel that things are catastrophic, despite most scientific evidence pointing the other direction. In this inspiring stream of thought, Kelly reminds us that society is constantly making progress, and that innovation is the direct result of optimism. Civilization is not a sweeping, heroic enterprise, he says, it’s a constant creep forward, and you only have to look behind you to see how far we've come.
Professor Patrick McGovern, a world authority on ancient alcoholic beverages, describes how alcohol had a profound effect on early societies.
Patrick McGovern, a biomolecular archaeologist at the University of Pennsylvania, has one of the coolest jobs in the world. Some have called him “the Indiana Jones of Alcohol” or “the beer archaeologist”. What he does is recreate the world's oldest drinks by finding and utilizing organic material at archaeological sites. A world authority on ancient alcoholic beverages, he’s found humanity’s oldest drinks and re-made some of them, like a beer from the legendary King Midas's court and a 9000-year-old Chinese rice and honey drink from the Neolithic period.
