Hands-On Review: 802.11g Wireless Network Starter Kit from U.S. Robotics
The Straight Facts:
Pros - For systems with a USB port, it comes with everything you
need for 50 bucks. Install, setup and use were easier than with
other 802.11g wireless systems that I have tested.
Cons - The most difficult process was...
Health and Gambling Correlates Among the Elderly
Many people believe that gambling and health have a negative correlation; that is to say the more one gambles, the more health problems she can expect to encounter. It seems like the newspapers are always full of stories about down on their luck...
Human Origins
The issue of human evolution going back at least 9,000,000 (nine million) years and possibly even being upright by that time is another of the facts which when in my youth seemed totally ridiculous. Actually many mystics said it goes back twelve...

A cluster of atoms
Imagine a new variety of compounds; compounds that have properties never seen before or simply compounds that have properties more pronounced than those which we already know of at present. It would be really cool. No, in fact it is really cool! Indeed, an entirely new class of compound is on the verge of getting everybody’s attention.
Only some times back, it has been shown that a new division of compounds could exist. A new study now confirms the idea that a cluster of atom of an element, behaves differently from a single atom of the element. It is as if, a new element is being created.
For example, a cluster of 13 aluminium atoms behaves like a halogen (chlorine, bromine, iodine, etc). In addition, the aluminium cluster can react with halogens to form halogen compounds with novel properties!
However a cluster of one more aluminium atom, that is to say, 14 aluminium atoms, will act not like a halogen but rather like an alkaline earth (calcium, barium, etc) atom. And the ions that are hence formed are in fact totally new types of salts! For instance, when the 14 aluminium
atom cluster reacts with 3 iodine atoms, an ion with an absolute charge of –3 is formed. Surprisingly this resulting ion is very stable.
The atom cluster thing has also been a source of debate in the scientific community. According to Shiv Khanna, co-leader of the study, the periodic table must be altered to accommodate the clusters or ‘superatoms,’ as he calls them.
How? Simple. Just add a 3rd dimension to the periodic table. The 13 aluminium atom cluster will then be in the same row and column as iodine since it acts more or less like the latter. Only difference is that it will be in a new plane. Same thing for the 14 aluminium atom cluster in the alkaline earth group and for the other ‘superatoms.’
As if the periodic table wasn’t complicated enough! But I guess that it will be even more so if the additions are made. So don’t you dare think that your generation’s college chemistry was hard!
