Simply spending time out in pastoral or wild landscapes counteracts this tendency. Spend a day in the woods and you will begin to hear a bit more a...

 How Photosynthesis Builds Energy Against Entropy

No law of physics is more basic than the law of entropy, the tendency of the universe to move toward disorder and death. But life bucks the tide. using available free energy wherever it can get it, and hereabouts the most abundant source of energy is sunlight. The mayflower constructs its tiny oasis of order by drawing upon a corresponding increase of disorder at the center of the Sun, where hydrogen is fused into helium. There, deep at the heart of our planet's star, is the source of the ene...

 Spring Recapitulates Evolution

Suddenly the woods are skittering, fluttering, munching. singing. From rock-hard seed cas...
