Computers

To start with, from the late 20th century to nowadays computers have been developing incredibly fast, up to a point in which we have became almost totally dependent on computers. It is important to mention the fact that not just computers have been in a continuous development, but also everything that relates to technology itself has been advancing, in terms of complexity, for example cars, mobile phones, etc. and I believe that in a near future everything will need computers in order to work correctly.

On the one hand, dependence on computers has its benefits, such as faster and more accurate communication, the ability to work with digital media and files, which makes it easier to pass files from one computer to another in just seconds. Computers are used everywhere at any time. In hospitals, offices, schools, restaurants, supermarkets, etc., you can see new models, new features and new uses every day.

On the other hand, the consequences of being dependent on computers may result harmful in many ways for humanity. For example, the use of computers takes a lot of time out from people lives and that is why many people complains about computers, by saying that kids, for example, instead of going outside and play football, stay at home playing computer games or chatting.

All in all, it can be said that computers are beneficial to humans up to a certain point, as it have its positive and negative consequences.

Computers

In this time of technology we're more interested to see the social network and play computer games than in see friends or play a football match.
Young people are loosing the contac with friend because it's easier go home and chat with eight friends at the same time or with people who they don't know than go by bike to your friend house.
There are many fact that demonstrate that people need to connect in social networks and its make the face-to-face contact obsolete (We can say that people are loosing us because of computer and technology).
Also, there are a new addiction and it is computer addiction
And the dependence to the computer is more day by day.
In the new generations the computer has sustitute telephones, television and many others means of communication.
In my opinion we have to back to our roots and use again the personal contact because it have thing that anything its going to sustitute.

Nanotechnology and its applications

Definition: Nanotechnology is the study of manipulating matter on an atomic and molecular scale.

Applications

Nanotechnology in medicine:
Nanomedicine is the medical application of nanotechnology.[1] Nanomedicine ranges from the medical applications of nanomaterials, to nanoelectronic biosensors, and even possible future applications of molecular nanotechnology. Current problems for nanomedicine involve understanding the issues related to toxicity and environmental impact of nanoscale materials.
