NPR’s Robert Krulwich has a whimsical piece on the one formula that rules it all, from unicellular organisms to whales and sequoias and humans. A math formula that governs our life and tells us when to die.
Even more interesting: the same system scales to other things too, like societies and economies. And it’s all bound by one seemingly magic number.
Physicist Geoffrey West describes it a very must-watch with Edge:
[…] if you plotted, for example the metabolic rate on the Y axis and size on the X axis, because of the extraordinary diversity and complexity of the system and the historical contingency, you would expect points all over the map representing, of course, history and geography and so on.
Well, you find quite the contrary. You find a very simple curve, and that curve has a very simple mathematical formula. It comes out to be a very simple power law. In fact, the power law not only is simple in itself mathematically, but here it has an exponent that is extraordinarily simple. The exponent was very close to the number three quarters.
First of all, that was amazing in itself, that you see scaling. But more importantly was that the scaling is manifested across all of life into eco-systems and down within cells. So this scaling law is truly remarkable. It goes from intracellular up to ecosystems almost 30 orders of magnitude. They’re the same phenomenon.
Furthermore, if you look at any physiological variable, such as the rate at which oxygen diffuses across lungs, the length of the aorta, anything to do with the physiology of any organism, or if you look at any life history event like how long you live, how long does the organism live, how long does it take to mature, what is its growth rate, etc., and you ask how does it scale? It scales in very similar way.
That is, it scales as a simple power law. The extraordinary thing about it is that the power law has an exponent, which is always a simple multiple of one quarter. What you determine just from the data is that there’s this extraordinary simple number, four, which seems to dominate all biology and across all taxonomic groups from the microscopic to the macroscopic.
Bangalore: Internet has grown into another world where everything is as easy as clicking few buttons or just gliding tip of your finger on smooth screens- be it calls, messages, social connections, information, movies, music, millions of apps, or shopping. From down to dusk you use it and thank your good fortunes that it is available, but do you really know the internet at the end of the day? How big the Internet is? Who’s building the biggest data center and what people use the mobile Internet for? Read on to know the 10 such facts about how internet actually works as compiled by Business Insider.
10. Internet is growing at unimaginable rate every year
As per some experts internet is growing by an exabyte of data every day. An exabyte is equal to 1 048 576 terabytes. After exabyte comes the zettabyte which equals 1000 exabytes; and in 2011 no single data center could hold a zettabyte of information. As Cisco predicts, by 2016 the data centers will be sending 1.3 zettabytes over internet every year. That’s the equivalent of sending all movies ever made across the Internet every 3 minutes.
9. U.S spies to build the world’s biggest data center
The National Security Agency (NSA) is a cryptologic intelligence agency of the United States Department of Defense responsible for the collection and analysis of foreign communications and foreign signals intelligence, as well as protecting U.S. government communications and information systems, which involves information security and cryptanalysis/cryptography. NSA is said to be building a $2 billion data center in Utah that will be the world’s first to store a store a yottabyte of data, reports Wired. A yottabyte equals 1000 zettabytes.
8. Apple says its data center is greenest of them all
To power Apple’s data center, the iCloud, the Cupertino tech giant has been building its on power station at Maiden, North Carolina. It was also an answer by Apple to Greenpeace who accused the company of being a big polluter.
Apple said that they are building their own facilities that will provide over 60 percent of the clean power the company needs. The company also added that they are building what will be the nation’s largest private solar arrays and the largest non-utility fuel cell installation operating anywhere in the country.
7. A good chunk of the Internet is all about Facebook
Facebook, the largest social networking site in the world in September hit a billion users mark that means it is a good chunk of the Internet.
Facebook accounted for 1 out of every 5 pageviews on the Internet worldwide, as of early 2012, according to researchers at Hitwise. The site stores 220 billion photos, and since launching features to support music apps like Spotify in September 2011, 62.6 million songs have been played 22 billion times—that’s about 210,000 years of music.
6. People use the mobile Internet to stay healthy
Accessing net on the Smartphone is hugely popular in recent times. These smart devices have became ubiquitous hence internet is made available 24 by 7. Besides obvious tasks like phone calls, texts, and Web surfing, one of the most popular things to do with a phone is to track one’s health. According to Pew Research Center, provides information on issues, attitudes and trends shaping the United States and the world, about 52 percent of Smartphone owners gather health information on their phones and almost 20 percent use their phones for health apps, particularly diet and fitness apps.
5. People use the mobile Internet to bank and buy stuff
Other than health tracking the internet is used by 33 percent of Americans on theirSmartphones for mobile banking and 27 percent uses it to shop. Some 25 percent make online payments. And 7 percent purchased goods from an auction site, according to research by the National Cyber Security Alliance (NCSA) and antivirus vendor McAfee.
4. Half of Americans watch TV over the Internet
With networks offering 3G and 4G data speeds and Smartphones being robust with technology, over half of Americans have watched TV streamed from the Internet. This has already become a favorite way to watch for people under the age of 35 versus live TV, finds research Harris Interactive.
3. Internet can save you over $8,000 a year
Having access to a high-speed broadband Internet account can save a family about $8,400 a year, says the Internet Innovation Alliance. With so much of the online shopping happening, people can save this money by using the Internet for daily deals and to comparison shop. They also save the most money on entertainment and dining out but they also save on travel and everyday necessities like food and clothes. The Cyber Monday gig in U.S. can be a best example for saving money upon shopping online.
2. But “high-speed” is a relative term
The average worldwide download speed is 580 kilobits per second; Pando Networks found when looking at 27 million downloads by 20 million computers in 224 countries in a study conducted last year. When it comes to U.S., it’s slightly faster than that, with an average speed of 616 kilobits per second, or Kbps. South Korea has the fastest Internet, with an average speed of 2,202 Kbps and the eastern European nations of Romania (1,909 Kbps) and Bulgaria (1,611 Kbps) landed in second and third place.
1. Too much Internet is bad for you
Sure internet is the zing thing and beingonline may makes you feel connected. But according to the researchers at Sweden’s University of Gothenburg people who spend a lot of time online tend to be stressed out and depressed and that time spent on the computer and mobile Internet made people feel like they could never relax and disconnect.

Apple is planning about 500,000 square feet of data center space in a single building. That would place it among the largest data centers in the world.
Apple is building a new data center facility in North Carolina. Nobody knows what is it for, but according to Data Center Knowledge editor Rich Miller, it will be one of the largest in the world.
Let’s put things in perpective: Apple’s current data center in Newark is a little over 100,000 square feet, while most data centers around the world don’t pass the 200,000 square feet mark. The new one, located near one of Google’s large facilities in Maiden, NC, will be a colossal 500,000 square feet. That’s a lot of computing nodes, and massive storage space.
The big question here is: Why? Is this designed to accomodate the iPhone family growth? Or is there a secret product and service plan that will require this gargantuan power and storage? New expanded content for new devices? Books? It can’t be only that.
Your guess are as good as Miller, myself, or anyone else’s, like with everything about Apple. Tell us your ideas in the comments.
Here is mine: According to the note I got in this bag of Cheetos, Apple is building a massive neural network to hold a duplicate of Steve Jobs’ brain, so he can run the company for ever and ever. Just don’t tell it to Jim Goldman. [Cult of Mac]
