synthetic character of chemistry sets it apart from the "discovery" sciences such as physics, biology, astronomy and the Earth sciences. "Chemistry creates its object" as a French chemist wrote in 1860. The downside of this focus on making stuff is that chemists can be portrayed as inveterate tinkers - tweaking the molecular world to satisfy their curiosity, sometimes for fun and sometimes for profit. And it makes it especially hard to see where industrial chemistry ends and academic chemistry begins. Recently in 2006, the Nature magazine asked many leading chemists what are the field's big questions. They have come up with six very important subjects in the arena of chemistry (Figure 12-37): | |
