Ice on top

As I've mentioned, I'm taking a summer course right now- Biology 106 & 107 (the lab).  It's kicking my ass. It's so hard for me.  I was never strong with sciences-- I know, I know-- WHY try to get into nursing if you suck at science??   Any way, it's hard.  Kind of stupid or naive to take this class over the summer, as opposed to a "normal" semester.  It's cramming 5 months worth of information into 8 weeks..  So we basically have to read the texts and lab books, and the pdf/ power point handouts and learn it at home, and be ready to ask questions in class.
With that said, I've been surprising myself often by the practical knowledge that I've picked up during the past few weeks of this class..  like yesterday, when my older sister and I were talking about the hydrangeas in my yard, and how they were wilting from the extreme heat we had this week.  Just to be a smart ass, I said something like, "well sure, it needs water to fill it's central vacuoles and restore the turgor pressure...."  Another night last week, I made myself a cocktail to drink after the boys were in bed-- I pre- made it before dinner, and then stuck it in my fridge for later.  When I took it out, there was a thin layer of ice on top.  I guess because it was in the back of the fridge, and had ice cubes in it?  Anyway, the first thought that popped into my head was the paragraphs I had read about how water molecules differ from most other molecules in freezing temperatures.  Most molecules will slow down, and in a sense, contract and take up less space.  Water, on the other hand, expands when it's freezing, and so it takes up more volume.  (that's why our beer bottles will explode if you forget to take them out of the freezer!).   The text book explains how this reaction is necessary for our entire planet's survival in many ways-  by the ice expanding, it forms on the top of the water, as opposed to sinking to the bottom.  So it serves as insulation to keep the temperature of the waters below from freezing, therefore allowing the aquatic animals and plants to thrive during the cold... and so forth and so on.   I also learned a whole bunch about all the tiny things that make up a cell, and all the insanely tiny things that go on that keep the cell functioning, and therefore keep us alive.  I learned about bacteria, and how there are so many aspects of bacterias and their compositions that are specifically designed by nature to try to beat our immune systems and thrive (and as a result make us sick and/or die).
So what's my point with all this reeeally boring science ranting?
It's so basic.  Life is so NOT random.  Everything that occurs in life from the tiniest atom of a molecule of a cell.... to the biggest things that occur like our choices of diet and friends, and environment etc is already all planned out for us to an extent.  Someone or something greater than us has already thought it all through. Someone or something has already thought of every single minute detail involved in life.. so why or how could we possibly imagine that He, or It didn't also think through our personal, individual lives? Of course He/ It did.  There's no way that every living thing on this planet is so perfectly designed, but our personal battles and victories are just by accident.
 We are merely all going through the motions, as we were designed to do.  I think the script has already been written.  We are all exactly where we're supposed to be.   We have to go with the plan, do our bests- for ourselves, for our kids, our family and friends, and hope that our own personal scripts have a happy ending.  So stop worrying so much all the time...  the final scene has already been written- you just have to wait and see how it ends.
