Laptops And Other Gadgets Make Offices Portable

Thanks to recent technological developments it's now possible to get work done no matter where you are. That's because there are a lot of gadgets available that will let you set up an office just about wherever you want.

High Definition Television

High Definition Television, or HDTV for short, is the entertainment technology of the future.It surpasses the quality of standard definition television in many impressive ways. The resolution of High Definition Television is ten times greater than the resolution of standard definition television and the picture is delivered in the same 16:9 aspect ratio of a movie theater. This added viewing area will make you feel like you're part of what's happening on the screen. Sound is delivered through Dolby Digital 5.1 Surround Sound, which when used with the right configuration of speakers adds to the sensation of being part of the action. Of course to take advantage of these extra features, you need special equipment. An HDTV capable television has to have the wide format 16:9 aspect ratio and needs to be able to handle the higher resolution. In other words it needs to be capable of packing more pixels into any given area. The sound system most frequently consists of two speakers in the front of the home theater by the television, three behind the couch or chairs where people watching the television will sit and often a sub-woofer under the couch.

Blu-ray Technology Still Faces Obstacles

Despite the fact that Blu-ray now longer has the competition of HD DVD to contend with, this technology still faces numerous barriers to its widespread adoption.First some background on Blu-ray. For the uninitiated, Blu-ray is a video disc format that can deliver HDTV quality video and is meant to replace the older DVD format as the home media format of choice for the foreseeable future. It accomplishes this with much greater data storage capacity than the DVD thanks to blue violet laser technology that can encode information more finely. This means that a Blu-ray disc, which is the same size as a normal DVD, can store roughly five times as much data! That extra capability to store data allows the Blu-ray disc to store video with a high enough resolution to qualify as HDTV. In fact, Blu-ray is capable of delivering movies with resolutions as high as 1080p which is the maximum for the HDTV format and better than most TV services can provide.Perhaps the biggest barrier to the wide spread adoption of the Blu-ray format is the DVD format that it is meant to replace. There are a number of reasons for this. First of all, there is some widespread fatigue of upgrading to new video formats. DVD has only been available for a little more than a decade and many users of DVD technology simply feel that it is too early to upgrade to a new format. The last obstacle that Blu-ray has to conquer is economic rather than technological. In a tough economy, people just aren't buying as many electronics. Devices like Blu-ray players and Blu-ray discs are far from being necessities and they are still too expensive to qualify as impulse purchases for all but the most wealthy electronics enthusiasts. For these reasons, it may be a while before Blu-ray gets the dominance that it was meant for.

Video Technology is more portable than ever

If you think that you are too busy to watch TV, then there are a few new kinds of technology that you should have a look at. That's because there are more ways to watch TV while you are on the go than there ever have been before! If you think that portable TV means having to be subjected to those lousy hand held TV's with the tiny LCD screens (often in black and white), then there are some other options that you can look into and more options coming out all of the time.It is still possible to watch TV on portable devices, but now it's more likely to be on a mobile phone or a smart phone than those older devices. Unlike the old portable TV sets that were dedicated to receiving over the air TV signals, the video that you can watch over a smart phone comes over a 3G data network that also provides Internet access. This video can come in the form of a proprietary service that's native to your mobile service provider or it can come from over the Internet. Many smart phones also have WiFi capability that can be used to access streaming Internet video while accessing a WiFi hot spot.All of the portable video options available today can allow you to enjoy TV in the idle moments that pop up occasionally during your otherwise busy life!

This book was one of the biggest hits of Asimov, and contains the laws of robotics by Asimov set out and accepted by other authors. This book consists of 9 stories, which deal with the evolution of the robots over time. The first story is entitled "Robbie," a robot nanny, unable to speak, is broken and repudiated by the people of Earth, and is thus prohibited the use of robots on the planet. At last count, the Earth is governed by the "Global Coordinator" Stephen BYERLEY (under which hang suspected to be a robot) that manages the Earth through the use of 4 "machines" that dictate the operation of production, consumption and use of labor.

Contents:

"Robbie"
"Runaround"
"Reason"
"Catch that Rabbit"
"Liar!"
"Little Lost Robot"
"Escape!"
"Evidence"
"The Evitable"

The Movie:

I, Robot is an American movie, based in the future, was launched on 16 July 2004 by 20th Century Fox I, Robot is based on the book by Isaac Asimov, more precisely, on the famous Laws of Robotics created by the writer. In their stories, Asimov played with the various implications of the laws of logic, creating absurd situations and dangerous for humans involving the robots, but also resolved in a logical. In the film, however, the same thing is resolved on the basis of much beating and harassment, as is usual in the production of action movies.

Robotics

The robot belongs to a branch of technology, which involves mechanical, electronic, computing and artificial intelligence. Currently, the robot is found in systems consisting of automatic machines and mechanical parts, can be controlled manually or automatically by electrical circuits. Although these machines are made and mechanisms, sometimes we can say that they are "alive", but nothing more than a simple robot. The robots are increasingly used by humans to do their jobs. And in future, the robots can control everything. The robots do not dream, do not feel, nor tire, because they are only machines. Today, due to reduced costs of robots, this technology is highly required by factories and industries, because they contribute positively to the increase of production.

The Robot in Society:

In our society a great need to perform tasks with efficiency and precision, and there are also tasks in places where human presence is difficult, risky and sometimes impossible, for example: at the bottom of the sea or in space. And instead of humans, robots are used, not at risk of life, to achieve these tasks.

There are robots in several areas in today's society:

Robots disarming of bombs.

Robots in science education and the study

Robots workers

There are different types of robots:

Intelligent

Control computer


Learning


Manipulators



Impacts on society:

With the development of robots, will appear many social impacts, but the most problem is unemployment. In factories, to be achieved greater productivity and quality in products, more economic, computers and robots are recruited guided by a need for survival in the market. But the workers, they are terrified, because a robot replaces sometimes tens or even hundreds of men in the production line.

Isaac Asimov, American writer of science fiction, set the 4 laws of robotics:

1st: A robot may not injure a human being and not by default, allow any evil to happen.

2nd: A robot must obey the orders of humans, except when they contradict the First Law.


3rd: A robot must protect its integrity, provided that, with this, not in the First and Second Laws.

4th: "A robot may not cause or allow evil to humanity that it does."

Agriculture Nowadays

Tha agriculture is one of the ancient type of work, but it suffered a lot of changes.

The modern agriculture apeard after the first fase of the Industrial Revolution, with the appearance of electricity. This called new technologies reinvented the agriculture, it became much more easy to work in the fields, and the level of production increased.

In my opinion the new technologies inproved a lot the agriculture, but in other cases I think that the new technologies are ecoming much too powerful...
