The rule of 72

The rule of 72 is used to find the number of years it takes to double your money at a given interest rate.

(72/[interest rate]) = years until a principle doubles



So, how long will it take to double your money at eight percent interest? Divide 8 into 72 and you get 9 years.



If you collect 7% on your savings in a little over 10 years the amount will be double what it is today.


The rule of 72 also means that you can determine the time
it takes for a population to double if it is growing at a steady rate by solving this function:

(72/[rate of growth]) = years for population to double

The Integration Age

"We have entered the Integration Age " - Steve Jobs CEO Apple...

The integration age has been mentioned for nearly a decade as a product name or marketing slogan. Now in 2007 it's hard not to see that a new era has arrived.


The integration age is the evolution of the information age. The integration age is made possible by the evolution of information management (search engines, bill pay, etc.) and information sharing (wikipedia.org, meetup.com, myspace.com) .

In fact a whole new generation of businesses that emerged (or came of age in Apple's case).
Google, Apple, eBay, Amazon, PayPal, myspace.com, youtube.com, craigslist.org, technorati.com, del.icio.us are just some of the big winners.

They share a common bond, right? They helped facilitate the creation and navigation of information and in the process dramatically affecting what is now possible.


The integration age is marked by globalization and specialization. It means highly integrated and efficient systems on the macro level thanks to specialization on the micro level. It is an age where Walmart rules because of their ability to effectively manage moving pieces. Did you know that Dell does not build computers and Nike does not make shoes?

The information age meant more information than any person or corporation could possibly handle, and businesses that specialized in the information age thrive in the integration age.


It is the IPhone that will likely be the symbol of the dawn of the integration age. An elegant merger of technologies, who would've thought it would take so long to merge the cell phone with the music player effectively.


Evidence that the integration age is well under way is seen in more and more places every day.


You can use www.salesforce.com to find clients, subcontractors off the Internet to implement services, and an accountant to keep track of it.
VA hospitals can access patient records from any location

Today's vehicles offer GPS, video screens, satellite, radio, oh, and talking maps
Social networks like www.myspace.com, www.blogger.com, and www.youtube.com, and open-source software all leverage information-age technologies to create a new type of social system that has had a profound impact on culture and the media.
You can now run Windows on your Macintosh
hackers now can control massive networks of zombie machines (1.5 million computers in one case) that act in co-operation (called botnets). These botnets might peddle spam and attack networks.


Welcome to the integration age.

Can I Get Pregnant From A Dog?

As of April 2010 you can visit Google and type in "can i get" and see the auto-suggestion of.... "can i get pregnant from a dog!" The Google suggest feature is intended to suggest the most likely search given the current term based on actual search volume! Let's hope it's malfunctioning in this case.

The answer is of course, "NO"! Why? According to wikianswers dog sperm can penetrate a human egg but the egg will die immediately because the male & female chromosomes don't match. As a general rule different animal species can not produce offspring. However, some animals have been to known to have virgin births!
