1.      Ordered Chemical Resource Encyclopedia (OChRE) – As of 3-22-05, most chemical substance nomenclature (naming) manuals I’ve consulted use categories and subcategories to name specific elemental combinations.  For example, to find the names of NaCl (salt) or FeO2 (Iron Oxide or Rust), the book may be broken into groups like metals, alkaloids, or hydrocarbons.  One seems to need a certain level of chemistry to use these resources.  A means of organizing this information in a more accessible manner uses the existing order of the periodic table combined with combinatorics (the mathematical art of combinations and permutations). 

a)      Levels of the OChRE – All substances would be classified simply by their elemental totals.  H, hydrogen, would come first.  Next, He, Li and Bo follow as well as all other single elements.  After all the single combinations comes the 2 element category, then 3, then 4, then 5, and so on.  Ionic and isotopic combinations would fall under the same elemental totals.  The OChRE accounts for this by either placing this information in order after the elemental total being looked at or by simply pointing to a separate index for that compound.  Personally, I find it easier to think of the pointers, which would eventually lead to all known substances and their order.  For example, if I had H2O2 (Hydrogen Peroxide) and (H2O2)-1 and even +1H2O2-1 (the last two I just made up for example), all would be under H2O2.  To find the molecule’s specific qualities, the global reference for H2O2 would send you to a different book in the encyclopedia, say the local book specializing in only compounds/molecules H2He through H2Mg.

b)      Using human visual parameters and the maximum size of a molecule to limit the size of the OChRE. – Fortunately, OChRE’s size seems limited to a maximum number of combinations.  The human eye can distinguish pinpoint sizes not much smaller than thin hair or a pin point.  Let’s estimate this between one tenth and one twentieth of a millimeter (5*10-5 meters).  Then, since hydrogen is the smallest atom, we take its familiar Bohr radius (.0529 nm = 5.29*10-11) and do a simple volume calculation.  One finds this equals about 8*1017 atoms in a group before the human eye could see it.  That’s 800,000,000,000,000,000 atoms, and wow does that seem like a lot.  In fact though, a more accurate measure of the limit of number of elements in one compound would be lower for a few reasons.  First, all other atoms are larger than hydrogen and therefore would take less to become visible.  Also, the atoms are slightly spaced further decreasing the total.  Yet another limiter are chemical relations that are already in place governing molecule react ability, stability, configuration and such.  

Non-Drip Gas Nozzles

This area is reserved for a project regarding the current ongoing hazard of gasoline nozzles at fueling stations. I have calculations to show the hazard as well as ideas for solutions.
