They sent us cutting templates, which were pieces of 3D modeling that we were able to place on the child’s skull during surgery

Both Egnor and Duboys said the 3D modeling technology helped to cut down on the length of the procedure, which meant Gabriel spent far less time under anesthesia than during traditional surgery

But it took a long time for solar sails to go from concept to reality. The first successful demonstration of the propulsion system didn't come until 2010, when Japan's Ikaros probe deployed its 46-foot-wide (14 m) sail and became the first craft ever to cruise through space on the backs of photons.

The $27 million Sunjammer mission, which takes its name from the Arthur C. Clarke story, will use a sail built by California-based company L'Garde that measures 124 feet (38 m) on a side. The sail, made of an advanced material called Kapton, is just 5 microns (about 0.0002 inches) thick. It weighs less than 70 pounds (32 kilograms) and packs down to the size of a dishwasher, NASA officials have said.

If you answered yes to any of those questions, exposure to technology may be slowly reshaping your personality.

Some experts suggest simply trying to curtail the amount of time you spend online. Set limits for how often you check e-mail or force yourself to leave your cellphone at home occasionally.

Presence is widely accepted as the key concept to be considered in any research involving human interaction with Virtual Reality (VR). Since its original description, the concept of presence has developed over the past decade to be considered by many researchers as the essence of any experience in a virtual environment. The VR generating systems comprise two main parts: a technological component and a psychological experience. The different relevance given to them produced two different but coexisting visions of presence: the rationalist and the psychological/ecological points of view. The rationalist point of view considers a VR system as a collection of specific machines with the necessity of the inclusion of the concept of presence. The researchers agreeing with this approach describe the sense of presence as a function of the experience of a given medium (Media Presence). The main result of this approach is the definition of presence as the perceptual illusion of non-mediation produced by means of the disappearance of the medium from the conscious attention of the subject. At the other extreme, there is the psychological or ecological perspective (Inner Presence). Specifically, this perspective considers presence as a neuropsychological phenomenon, evolved from the interplay of our biological and cultural inheritance, whose goal is the control of the human activity. Given its key role and the rate at which new approaches to understanding and examining presence are appearing, this chapter draws together current research on presence to provide an up to date overview of the most widely accepted approaches to its understanding and measurement.

Within these contexts, the act of arranging objects, images or sounds into an order that may or may not have meaning has proliferated throughout the creative and cultural industries. The curator is now a producer: you might curate your Flickr feed, your mates playing records at a bar or an exhibition in your own apartment – a trend showcased by the Serpentine Gallery's co-director Hans Ulrich Obrist, a master orator of what he calls a "global dialogue… in space and time".

A space has now opened up – both physically and online – where anyone can give curating a go.

What, then, if we're looking in the wrong place for qualified, ground-breaking curators? Perhaps they are no longer in museums, galleries or cultural institutions, but instead in front of a screen – sociable and connected. Curating in the age of the internet is the act of responding to social and technological developments: their usability, instability and the various networks of communication in which they are presented online.

Surfing the Internet has become a daily routine of the new generation.

The present generation especially the college students are well versed with the new technologies and their application in present networked society

the team located data about technology use and political opinion from before the revolutions. 

“Our evidence suggests that social media carried a cascade of messages about freedom and democracy across North Africa and the Middle East, and helped raise expectations for the success of political uprising,” said Philip Howard, the project lead and an associate professor in communication at the University of Washington.  “People who shared interest in democracy built extensive social networks and organized political action. Social media became a critical part of the toolkit for greater freedom.”

The social media allows for people to not only hear about what is going on, but actually see what is going on through the actual pictures of actual people.

it causes people to lack social skills and causes problems with jobs and school.

This causes a lot of issues for the people in the real world, as they cannot interact in the real world because they are too reliant on social media.

Accommodated as we are to mass media, we must work to imagine the impact of commercial radio broadcasting in its early years. From the late 1800s, new electronic devices had been expanding the realm of shared human experience — people conversed on telephones, sent news through telegrams, played records on phonographs, and enjoyed films in local theaters. But until the radio, nothing offered such widely shared simultaneous mass experience. By turning on your radio set, you could listen to a jazz band, baseball game, religious service, even a president’s speech, live, along with millions of fellow listeners.

People engage in an information search experience holistically, with an interplay of thoughts, feelings and actions.  Common patterns of thinking, feeling, and acting are characteristic in each phase.  These studies were among the first to investigate the affective aspects or the feelings of a person in the process of information seeking along with the cognitive and physical aspects.  Rather than a steady increase in confidence from the beginning of a search to the conclusion, as might be expected, a dip in confidence is commonly experienced once an individual has initiated a search and begins to encounter conflicting and inconsistent information.  A person “in the dip” is increasingly uncertain and confused until a focus is formed to provide a path for seeking meaning and criteria for judging relevance. Advances in information technology, that open access to a vast assortment of sources, have not helped the user’s dilemma and may have intensified the sense of confusion and uncertainty.  Information systems may intensify the problem particularly in the early stages of the ISP by overwhelming the user with “everything” all at once.
