Well it certainly wasn't a summer vacation, but it has been an extremely busy but productive one. One major project is winding down and there have been others at the same time, always with their most inappropriate timing for meetings and updates.
This is nothing new, but formulation work is long, difficult and full of failure. Every single formulation that fails is a kick in the teeth, since you obviously thought it would have worked or you wouldn't have tried it in the first place. (The exception is when management said to try it, but that's a whole other issue...) But this just makes success all that much sweeter.
While there still is room for improvement, we know so much more about chemistry and have much greater analytical techniques that 100 years ago when many of the foundations were being laid down. I always wonder how those pioneers did it, as they were half-blind at best. But they certainly did not see it that way, and 100 years from now, we will look similarly ancient and quaint.
