By: Jan Spitzer | Series: Vienna Series in Theoretical BiologyA reconceptualization of origins research that exploits a modern understanding of non-covalent molecular forces that stabilize living prokaryotic cells.
Scientific research into the origins of life remains exploratory and speculative. Science has no definitive answer to the biggest questions--"What is life?" and "How did life begin on earth?" In this book, Jan Spitzer reconceptualizes origins research by exploiting a modern understanding of non-covalent molecular forces and covalent bond formation--a physicochemical approach propounded originally by Linus Pauling and Max Delbrück. Spitzer develops the Pauling-Delbrück premise as a physicochemical jigsaw puzzle that identifies key stages in life's emergence, from the formation of first oceans, tidal sediments, and proto-biofilms to progenotes, proto-cells and the first cellular organisms.

Wide surface
Style: Lawn Edger/Tool Only
The edger has a very strong motor cuts great! As long as you are placing the edger on a wide flat surface. If the area you want to edge is along the curb and narrow the edger is to big and bluky for a narrow edge strip

After one use
Style: Lawn Edger/Tool Only
Not as powerful as I would have liked so the trim is not as smooth

Very good lawn edger
It does a great job and easy to create straight, clean lines. Does not do well going around curves.

Great value.
Works great, easy to handle, relatively quiet, and powerful enough to cut through 3 inches of sod.

Trim me up
The trimmer works as described. It arrived as promised, it manicured my 80 ft linear ft in no time. I ran 2 passes because I hadn’t done it in decades.
