Technologies for Measuring Avogadro's Number

Avogadro - his number It was long after Avogadro that the idea of a mole was introduced. Since a molecular weight in grams (mole) of any substance contains the same number of molecules, then according to Avogadro's Principle, the molar volumes of all gases should be the same. The number of molecules in one mole is now called Avogadro's number. It must be emphasised that Avogadro, of course, had no knowledge of moles, or of the number that was to bear his name. Thus the number was never actually determined by Avogadro himself. As we all know today, Avogadro's number is very large, the presently accepted value being 6.0221367 x 1023. The size of such a number is extremely difficult to comprehend. There are many awe-inspiring illustrations to help visualize the enormous size of this number. For example: An Avogadro's number of standard soft drink cans would cover the surface of the earth to a depth of over 200 miles. If you had Avogadro's number of unpopped popc…

My Rant About Google Chrome

Chrome is fast, and its made by Google so there is that feel-good aspect. But other than that it just plain sucks.
- Gears is not fully implemented, just try Google Docs offline
- There are no toolbars or useful plugins
- A crashed process in one tab is not supposed to crash the browser, but it will
- Google continues to create plug-ins and toolbars for FireFox and IE but not for Chrome.Bad, bad, bad!  They created a kickass browser and then stranded its users with no add-ons.I hate to say it, but it feels a tad uncaring and out of control.  What are they thinking?
My only consolation is my gut-feeling expectation that all the goodies are in the pipline and will be available soon.  I hope I am not wrong.
