This webpage started out as a collection of Google calculator moments experienced during the fall 2008 semester; however, these calculator moments have extended beyond 2008 and in a sense this webpage has become a blog of Google calculator moments.

Google calculator moments are listed in oldest-to-newest order...

MathBabbler learned from NumberGossip.com that "the number n is called an apocalyptic power if 2^n contains the consecutive digits 666 (in decimal)." While working on a nBAB for the number 1929, NumberGossip.com indicated that 1929 was an apocalyptic number and MathBabbler used Google to check if it was true.

MathBabbler was working on a BAB about loan-to-value and debt-to-income ratios when it went to Google to search for "31%". 31% has been in the news because the goverment might make it easier for homeowners to refinance if their debt-to-income ratio exceeds 31%.

MathBabbler uses a function named

cuberoot(n)when doing BARS. Out of curiosity he checked to see if the Google calculator had a "cuberoot" function and it does and it is named "cube root(n)."

Entered:(14 + 8) / sqrt(7^cuberoot(8))Result: Did you mean: (14 + 8) / sqrt(7^cube root(8)) ... clicked YES ... Result:(14 + 8) / sqrt(7^cube root(8)) = 3.14285714## Updated::2009.03.31

Entered:weeks per yearResult:1 year = 52.177457 weeksMathBabbler was surprised that "weeks per year" worked, yet "days per year" didn't.

## Updated::2009.04.06

MathBabbler went to NanoDay at the Arizona Museum of Natural History in Mesa on Sunday, 5 April 2009, and his height was measured to be 1.8 billion nanometers. Google was used to see how accurate the nano measurement was.

Entered:1.8 * 10^9 nanometers - 5 ft 8.5 in to nanometersResult:(1.8 * (10^9) nanometers) - (5 ft 8.5 in) = 60 100 000 nanometersThe measurement was off by 60.1 million nanometers.

## Updated::2009.04.09

During class MathBabbler used the Google calculator to see if we converted from scientific notation to integer. We converted 1.105 petaflops to 1.105 * 10^15 and wrote that value as an integer.

Entered:1105000000000000 * 1Result:1 105 000 000 000 000 * 1 = 1.10500 x 10^15We typed in a large number and multiplied by one because we knew Google's result would be presented in scientific notation.

Many times while using the Google calculator, MathBabbler uses 10^6, 10^9, 10^12, 10^15 for million, billion, trillion, quadrillion and so on. He tested the calculator to see if he could use the words rather than numbers.

Entered:1 * 1 duodecillionResult:1 * 1 duodecillion = 1.0 x 10^39... Entered:1 * 1 quattuordecillionResult:1 * 1 quattuordecillion = 1.0 x 10^45... Entered:1 * 1 sexdecillionResult:1 * 1 sexdecillion = 1.0 x 10^51... Entered:1 * 1 vigintillionResult:1 * 1 vigintillion = 1.0 x 10^63Entered:1 * 1 unvigintillion[did not compute; searched the web] [unvigintillion = 10^66] Entered:1 * 1 googolResult:1 * 1 googol = 1.0 x 10^100[note: 1st hyperlink to abc.net, not google.com]Note: When it comes to names for large numbers there are American names and there are European names. For example, the American name

sextillionhas the European nametrilliard.## Updated::2009.05.27

Spire Corp. received a patent entitled "Nanophotovoltaic Devices" that for "nanophotovoltaic devices formed from silicon or gallium arsenide having sizes in a range of about 50 nanometers to about 5 microns, and method of their fabrication."

Entered:1 micron to nmResult:1 micron = 1000 nanometersNote: The term

micronis short formicrometer. The abbreviationmmis used for millimeter. The abbreviationµmis used for micrometer, but theµdoesn't have a key on the keyboard.## Updated::2009.08.31

MathBabbler used Google to check if 8/31/09 written as a BAD (Basic Arithmetic Date) was correct.

Entered:sqrt(31 % 9) - cube root(8)Result:sqrt(31 % 9) - cube root(8) = 0The first hyperlink on the results webpage was to this webpage; i.e., GDT::BAB::Google Calculator Moments.
