Google Products
Google has come a really long way to make its current line of products.
Answers, Picasa, Local Mobile, Directory have all been terminated. Froogle has been changed to Shopping,
Labs, Pack and Catalogs all have been killed to be combined or simply renamed Google Search ("Web Search") since 2006 as shown on my blog (2006/5), while University Search has been renamed Custom Search and Special Searches, Search Help Center.
Still, Google Maps and YouTube and Gmail, which are not listed here, and Mobile, News, Docs, Translate etc. are all among its useful and thus popular products.
My favorite product is Calculator and Unit Converter. It is one of its products still remaining on Google's current product line but has now been categorized as "Types of search results" < "Search Features".
World Clock Time Zones in Excel .
This can be used to track radio programs in various time zones across the globe on my websites excelfan.com and Ken's Home Radio .
Here is my website Excel World Clock.
All my websites carries Google Search boxes.

Oil Is Up While Gold Is Down
There are ups and downs in prices of everything on the market. But historically, gold has been tested by time and proved literally rustproof thus become a symbol of imperishable value, substituted by people across the continents to retain wealth whenever they are involved in any crises, economic - say, the Leerman Shock in 2008 - or not - social upheavals like wars or depressions or natural disasters like earthquakes and floods and their fortune is deemed vulnerable and put at the risk of devastating loss. So there is an almost eternal belief in gold. They abandon their money, rushing it to the gold. Their behavior in this option is called 'flight to simplicity'.
However, gold can be of less and less value over the shorter period of time, like the past one year. Whereas oil has been more and more highly priced meanwhile.
Their curbs are shown dramatically opposite by the graphs in these Excel files:

Let Excel Show the Market Trend to Make Analysis in Investment
"Excel Gold Price Chart" or formally "Excel Chart: Daily Gold Price in US Dollar per Troy Ounce, London PM Fix" will help us analyze the trend of gold prices on the market. Who said that when the curb turns down is the time to rush your money to the gold? Sounds stupid unless decision is made by studying and analyzing data available on the market. Excel will be of great help.

(phi+1/phi)^2=5 as my Spreadsheet Shows
Binomial Theorem
Pascal's Triangle
"Mortgage terms are usually 15 or 30 years.
The longer the term, the lower your monthly payment,
but the higher your overall interest costs."
So says Mortgage Basics - Real Estate Guide on Yahoo! Personal Finance.
My spreadsheet can be used to calculate the "overall interest costs". Try the "Interest" sheet.
This is Pascal Triangle Pro. It has lookup functions for binomial coefficient and shows Fibonacci numbers in the triangle.

Another Decoding
"A Thousand Winds" has two versions. Thanks do not stand at my grave and weep - bereavement poem.
(do not stand at my grave and weep)
Do not stand at my grave and weep
I am not there; I do not sleep.
I am a thousand winds that blow,
I am the diamond glints on snow,
I am the sun on ripened grain,
I am the gentle autumn rain.
When you awaken in the morning's hush
I am the swift uplifting rush
Of quiet birds in circling flight.
I am the soft starlight at night.
Do not stand at my grave and cry,
I am not there; I did not die.
(do not stand at my grave and weep)
Do not stand at my grave and weep,
I am not there, I do not sleep.
I am in a thousand winds that blow,
I am the softly falling snow.
I am the gentle showers of rain,
I am the fields of ripening grain.
I am in the morning hush,
I am in the graceful rush
Of beautiful birds in circling flight,
I am the starshine of the night.
I am in the flowers that bloom,
I am in a quiet room.
I am in the birds that sing,
I am in each lovely thing.
Do not stand at my grave and cry,
I am not there. I do not die.

12 Pentagons Make a Dodecahedron
Polyhedron like dodecahedron will be explored with Excel to use polygon like pentagon as building blocks.
I have designed and drawn a chain of 12 pentagons to cut and fold to make a dodecahedron dice so we can play with our kids. Excel Trigonometry.

Martin Gardner Challenges us in "In the beginning God...."
2) And the earth was without form, and void; and darkness was
upon the face of the deep.
And the Spirit of God moved upon the face of the waters.
3) And God said, Let there be light: and there was light."
In "Wonders of Numbers" (Clifford A. Pickover, 2000), Mathematician Martin Gardner challenges the reader to find out that:
Start with any word in 1) above ('In' to 'Earth'), and count the number of (length of) the word (say 3 in 'the'): "n1";
and Proceed to the word n1 after the first word (say 'created'), and count the number of (length of) the word (7): "n2";
and Proceed to the word n2 after the second word ('created'),
and so forth, and the two 'God's (one each in 2) and 3)) will thus end up just n* after the preceeding words.
My Excel spreadsheet will help find out about this.

Correct? "phi - (((1 / phi) * (1 - ((1 / phi)^70))) / (1 - (1 / phi))) = 0"
phi - (((1 / phi) * (1 - ((1 / phi)^70))) / (1 - (1 / phi))) = 0 is not verified by what I figure out with my Excel Trigonometry.
06/12/12
((1 / phi) * (1 - ((1 / phi)^70))) / (1 - (1 / phi)) = 1.61803399, more precisely, means that:
- 1/phi + 1/phi^2 + 1/phi^3 + .... + 1/phi^70 is 1.618033988..
- 1/phi + 1/phi^2 + 1/phi^3 + .... + 1/phi^70 + .... + 1/phi^n
becomes indefinately closer to phi as 'n' increases to infinity.
Phi to 20,000 places
Note:
- 1/phi, 1/phi^2, 1/phi^3, ... forms Fibonacci Numbers
- Formula for the geometrical series for this:
(((1 / phi) * (1 - ((1 / phi)^n))) / (1 - (1 / phi))) - phi+1, (phi+1)^2, (phi+1)^3, ... also forms Fibonacci Numbers
