The Internet is a tremendous growth engine, responsible for 21% of economic growth in the more advanced countries in the world, according to a McKinsey study. While those of us in the United States complain about how we have to pay more for Internet service that's slower than those of other first-world countries, within the United States there's a gaping chasm between the haves and the have-nots. In this infographic by, an ad-free website describing itself as "an online informational resource for individuals looking to pursue IT degree of related education and careers," you'll find surprising information about the differences in Internet access in the United States.

Beyond that, you'll see more information about how the U.S. lags behind other countries in Internet technology, broadband speed and access. Physics or Fashion? What Science Lovers Link to Most [Interactive] People who are intrigued with physics are somewhat intrigued with computer science, too, but they are crazy about fashion. Who knew? Hilary Mason did. At Scientific American’s request, the chief scientist at bitly (, which shortens URLs for Web users, examined 600 science Web page addresses sent to the company’s servers on August 23 and 24. Then she tracked 6,000 pages people visited next and mapped the connections. The results revealed which subjects were strongly and weakly associated.

Top Tech Trends of 2011 (infographic) Stay Connected with Us!

Follow TechnoBuffalo So what can we learn from 2011? Well for one, according to this infographic, it seems people en masse absolutely do not like being hardwired. On the contrary, our affinity for sharing, streaming and being mobile has become a full-blown obsession. And why not? The tools we use are becoming increasingly powerful, after all. In other words, all we want is to do more and enjoy more, absolutely everywhere we are. For the full list of 2011′s tech trends, hit up the infographic below.

Internet of Things. Surface. The Manual Photography Cheat Sheet. The Manual Photography Cheat Sheet by Miguel “Mig” Yatco is a very cool infographic for anyone who is ready to move off of Automatic Mode on their camera! Yes, that means you! Quit taking average photos with average settings! No matter if you shoot with film or digital, understanding of these four aspects of photography are key to taking good shots.

I love how each one shows the reader the range of values, the impact of moving along the range to the pcitures and what the actual display looks like in the viewfinder on both Nikon and Canon cameras. The only thing I would have liked to see was a visualization of the changes to depth of field. How much range is in focus for each aperture setting? Miguel has prints available on Great job Miguel! Camera Selection Infographics - The 'What Type of Camera Should I Get' Chart is Realistic. If you are thinking about purchasing photography equipment, consider checking out the 'What Type of Camera Should I Get' infographic before buying more than what you need. Although many assume a DSLR is the ideal choice, it is important to consider what you really use your camera for before blowing hundreds on a high-powered device.

A DSLR is ideal for those who practice photography as their profession or when photo quality is of the upmost importance. If you are looking for DSLR quality without the bulk, mirror-less interchangeable lens cameras are quickly popping up on today's market. But if you see yourself taking everyday photos of your friends at parties, consider saving your money for brewskis and opt for a compact camera or simply use your phone's camera. The 'What Type of Camera Should I Get' flowchart is a helpful guide to figuring out what device best suits your needs. What topics science lovers link to the most. Hilary Mason, chief scientist at bitly, examined links to 600 science pages and the pages that those people visited next: The results revealed which subjects were strongly and weakly associated. Chemistry was linked to almost no other science. Biology was linked to almost all of them. Health was tied more to business than to food.

But why did fashion connect strongly to physics? And why was astronomy linked to genetics? The interactive lets you poke around the data, looking at connections sorted from weakest (fewer links) to strongest (more links), and nodes are organized such that topics with more links between each other are closer together.

Metals That Enable Our Gadgets Are Vanishing. It’s been widely reported that we’re running out of the rare-earth elements and various other metals that make our smartphones and computers run. But rarely do you get very precise information about how dire that problem is. It’s not that we don’t know--it’s simply that we haven’t had any decent information designers addressing the data. So having this nice little chart by Camden Asay is particularly useful: Given its clarity and concision, its no wonder that the chart actually won the $2,000 first-place prize in a contest run by David McCandless’s Information Is Beautiful. Of course, its very clarity makes you wonder about the data.

Granted, it all does come from very respectable sources such as the U.S. Geological Survey. But the second part is hard: As technology progresses, we use what resources we have with increasing efficiency. Increasing efficiency tends to increase the rate we consume a natural resource--a counterintuitive finding called Jevons Paradox. [Top image by EllenM1.

Planets Large and Small Populate Our Galaxy (Infographic) | NASA's Kepler Planet-Hunting Spacecraft | Search for Earth-like Alien Planets. Buy This Infographic as a Full-Size Poster Astronomers have discovered more than 700 alien planets beyond the solar system, and the count is rising all the time.

Some are large and hot, and others are smaller and cooler, but scientists are still on the lookout for an Earth twin. They just got closer, with the announcement Dec. 5 of a planet found by NASA's Kepler space telescope to lie in the habitable zone around its star where liquid water, and perhaps life, could exist.

" src=" NASA's Virtual Snow Globe Looks at 10 Years of the White Stuff. NASA has released a video that highlights where snow graced the Earth during every month for more than 10 years. The clip starts with a snow-covered map of the Earth on February 2000 and runs all the way up until last month.

The maps show observations collected by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite. Snow cover is depicted by color, from medium blue (greater than 0%) to white (100%). Regions that didn't get snow and weren't picked up by the satellite are displayed in gray. "Because MODIS relies on visible light to assess snow cover, the sensor cannot collect data over the highest latitudes of the Northern Hemisphere during winter when no sunlight reaches those regions," NASA said in a statement.

NASA also noted that snow and ice cover most of the Earth’s polar regions throughout the year. "Land area is larger and snow cover is more variable in the Northern Hemisphere than in the Southern Hemisphere," NASA added. 12 Visualizations That Will Change the Way You View Scale in Your World. Scale is a simple concept. From a very early age, children know about big and small, heavy and light, more and less. Extreme scales, however, are another story. Try to imagine, for example, the size of the universe… or $1 trillion made up entirely of dollar bills. Exactly. Grasping the actual quantities involved in extreme scales can be difficult, which makes managing scale in visualizations an interesting problem. Below are 12 visualizations that try to show things at extreme scales. 1. 2. 3. 4. 5. 6. 7. 8. 9.

Humans all fit within a small range of sizes, weights, and lifespans, and the quantities we deal with typically fit in small ranges as well.

The "Scale Of The Universe 2" is an awesome Flash animation packed with info. *UPDATE: Cary Huang, creator of “Scale Of The Universe 2″, answers some questions for the Hub. See his comments below.* An interactive Flash animation titled “Scale Of The Universe 2“, covering everything in the universe from the fabric of space-time to the estimated size of the universe, was posted earlier this year, and it is awesome.

A month or so later, it went viral, but why would something that comes straight out of an eighth grade physical science textbook become so popular? First, the actual scale of the universe is mind blowing as it spans 62 orders of magnitude (that’s multiplying 62 10′s together). While it is an incredible personal feat for the twins, the animation is also a testament to the creative and educational possibilities afforded by modern technology, and all the implications that that means for parents, educators, and publishers. But it was time for the power of the Internet to take over. Infographic Captures The Amazing Scale Of Space, Through Scrolling. Depending where you define the edges, our solar system has a diameter of at least 10 billion kilometers (and arguably more). How can the human mind begin to process such an expanse?

We can’t compare it to any meaningful time/distance relationship we’ve experienced--neither a football field nor a long road trip can serve as a reasonable metric--so what do we do? This extra-long infographic of our solar system, by Information Is Beautiful Studio, uses clever design schemes to scale the unfathomable expanses of planetary systems right within our browsers. Prepare to scroll for a looooong time: At its core is a waveform that serves as a scaling legend of distance.

As the graphic takes us from the Earth to the outer recesses of our solar system, this waveform condenses to help us cover more ground, faster. So in a single image, we can see the relatively tiny distance from Earth to the Moon and the massive expanses from the Earth to the edges of the galactic neighborhood.

Think you've got bad gadget spending habits? If you're a single male between the ages of 50 and 65 living in San Jose, Calif. your tech splurges might be par for the course, according to research by By aggregating anonymous data from the U.S. government, banks and other third-parties, Bundle has broken down Americans' gadget spending by city, age, household type and income level. While some of the findings are expected (monthly tech spending increases as the household gets larger), some are less so. For example, Madison, Wis. beats Seattle, Wash. in monthly spending, and 50 to 65-year-olds outspend their younger counterparts, on average. Check out all the stats in the infographic below, and let us know if you're surprised to see any of the findings. History of Apple. Apple iPad Buyer Is a Male, Pet-Owning Gamer. While the iPad is clearly a hit among lots of demographics, from non-reading toddlers to senior citizens, there are still certain sets of people that are more likely to go out and buy one of the Apple tablets.

The folks at marketing firm BlueKai have compiled some of that data into a handy infographic. Among the three characteristics most tied to iPad purchasing are being male, a pet-owner and into video games. Close behind are scientists, travelers (both international and domestic) and, bizarrely, organic food proponents. Perhaps the latter, though, is tied to having the kind of disposable income necessary to purchase a device that, while undeniably fun and useful, likely doesn’t replace any other device. Of course, as previously mentioned, the tablet’s popularity extends even to female liberal arts majors who don’t care whether their food is processed. Apple Evolution: 30 Years in 2 Minutes.
