Osmosis History

We recently requested a professional review for our book “Osmosis: The Molecular Theory”.      That was again an interesting experience.     We have had the opportunity to find reviewers who are incompetent or dishonest.  Sometimes it is difficult to spot the difference from a short conversation.  So,  we will review osmosis history once again.    Osmosis was discovered ….  Read More

My Tree Leaks

My Tree Leaks This year, I discovered that my maple tree leaks.   A wet spot appeared on the sidewalk near the base of the tree.   The weather was below freezing at night and warmer in the day. The tree trunk remained below freezing during the day.   As noted in the maple syrup discussion, we proposed: ….  Read More

Pressure

Vapor Pressure II As we noted previously, the osmosis process of molecular movement through a membrane is directly related to vapor pressure difference.  This agrees with other models for fluid flow.    Flow is directly related to pressure difference and flow proceeds from a high-pressure area to a low-pressure area.   But, what is pressure?      We introduce ….  Read More
