Marie Curie

Fecha Friday, 27 February 2009


Marie curie is one of the people who have influenced me the most due to two main achievements.
She was born in Poland in 1867 where she lived all her chilhood. At the age of 24 she went to Paris where she obtained her higher degrees in chemistry, her favourite subject. After having finished her degree, she began her scientific career in Paris with an investigation of the magnetic properties of various steels. It was their mutual interest in magnetism that drew her to her husband Pierre Curie.
It was one evening in 1902, when she was going to come back home, when she turned and realised that she had finally isolated the uranium in which she had spent the last three years of her life.
Because of this discovery she was awarded the Nobel Prize twice in her life. The first time it was the Physics one in 1903 and in 1911 the Chemistry one.
She was the first woman to be awarded a Nobel Prize and the first scientist that won it twice.
The reasons why I admire her so mucho are obviously the awards she received and the fact that she didn’t come from an important or rich family, so all her achievement was the result of her efforts.
She died in 1934 of an illness contracted from her exposure to radiation. She was buried at the cemetery in Sceaux with her husband, but in 1995 the remains of both were transferred to the Paris Panthéon. She is the first woman so honoured.

The advantages of tools such as Facebook or Tuenti far exceed the risks

Fecha Friday, 27 February 2009

Could you imagine your personal world as it was 20 years ago when mobile phones did not exist and the internet was an unknown tool? Nowadays it seems to us that was a strange and distant time.  How could we live without mobiles, how could we survive without social activities thanks to the internet..?
Nowadays is a common and easy and widely way for personal relations: fast, immediate, plenty of possibilities. You can meet anybody from anywhere. Contact is immediate, the place and the time is not a problem and it is possible to be in touch with friends and family permanently.
While it is true that the advantages are evident, it must not be forgotten that this “happy world” has also great disadvantages:  one of the most significant is that your personal information can be used for immoral or illegal purposes, and, always the greatest risk is for defenceless children and teenagers.

The problem is not the tool but its bad and erroneous use. But, what can we do?.  Is not easy and the challenge is enormous. On the one hand, the use must be ruled and controlled by strict laws and, on the other hand, the best way for using this marvellous tool in an appropriate way must be efficient information and education and parental protection.

Social nets

Fecha Friday, 27 February 2009

Have you ever heard of social networks over the Internet such as Tuenti or Facebook? Social networks are being popular these days. However, there are some drawbacks you should know in case you are considering the idea of joining one of them.
Their main advantage is you can make a lot of friends and share information, posts, videos, songs,…etc. And the most important risk is these sites include search engines which let people in the Internet find you, but these people might not be your friends. These people can be anyone into or out of these nets depending on the searching criteria they are set into, by default or by you -if you are allowed to set this. These people, whoever they are, just have to type your user name to find you and all your friends lists, they may know things like what pages you are visiting.
So you have to be careful not to  include many details about yourself when you create an account, and set all settings in order to restrict or grant access to your privacy by allowing or not other networks link information on your activities in the Internet.
Remember there are hackers and computer freaks who could use this information to enter in your email, your system, and use this information to empty your credit card accounts.

Nowadays Facebook has become a very popular way to be in touch with friends. It is a way to know about people that you haven´t seen for ages. The only thing you have to do is to open an account, and you can start inviting friends, posting photos and videos that you want to show. As soon as your friends accept your invitation, you can see theirs.
It is a funny and easy way to communicate with your friends, even if you only want to let them know that you still exist. Just post some nice photos in your profile and sometimes write or comment something you have seen in other friend´s profile. You will be able to be updated about your friends´ lives, specially if they live in another city or country.
On the other hand, it is amazing how much time you can lose sailing through this page, just watching photos and videos, or updating your personal profile. The more information you post and friends you have, the less privacy you get. As your friends can post in the net some information you might not want to be showed, facebook could easily become a kind of privacy problem.
We must be careful about the different tools that internet provides us with and specially how we use them. I think that it is still early to make a proper judgment, let’s let the time show us if facebook will reach fine or appalling reports.

Social Nets

Fecha Friday, 27 February 2009

Some websites such as Tuenti, Facebook, Fotolog,… are becoming more and more commonly used nowadays. These computer tools are called social nets by its creators and its users. This means that you may create your own virtual community from your own sofa. This idea might sound interesting and even funny but, where do we have to set the limits of privacy? 

The main point in favour these tools have is that social activities are not finished when you go back home because you can chat, share photos or videos or even flirt online. Moreover, it is a way of keeping in touch with old friends or with relatives far away from your home. Another benefit lies on the non-face-to-face conversation, which may help introvert people.  

Nevertheless, there are also some risks which should be taken in account when we use one of these social nets. The most important drawback is the loss of personal privacy because too much personal information may be unconciously shared. In addition, personal identity may be hidden or changed, which may lead to really serious problems such as sexual harrasment or pedophilia.  

Taking everything into consideration, it seems that social nets may contribute to improve our social interactions, although we must have in mind the extent to which our personal life is in the public eye. Finally, the human being tends to lie and lie and lie, which may be even more easily done on the Internet, therefore we must be aware about what is real life  and what is not.

Tuenti and Facebook.

Fecha Friday, 27 February 2009

Internet social tools such as Tuenti and Facebook have developed in the last few years. Young people use them to communicate and to create online communities where they can talk, share documents, songs, videos and photos with their friends. They can also be used to meet new people all over the world.

However parents are always worried about the risks this activity can involve. It is important to remember that almost everybody can look for your photos and documents in the net if you don’t protect them properly. Both Tuenti and Facebook have the possibility of giving your private information only to your friends, but most of the people prefer leaving the entrance free to everybody.

While it is true that you have the choice of avoiding the admission to your account to someone, it must not be forgotten that they are able to create a new identity to reach this person. Although it could be argued that with this new means communication informarioncan be available to everybody whilst you are writing it, it is also a fact that they can destroy the traditional means of communication we have.

Taking both sides of the argument into account, I would say that it depends on the way you use them whether they can be useful or not. Only by using them in a responsible way we will take all the benefits they can provide us.

The advantages of tools such as Facebook and Tuenti for exceed the risks. Discuss.

Fecha Friday, 27 February 2009

Facebook is probably the best example of a social network. It allows users to take part in a community with their own pictures, blogs games… in a much better way than MySpace did. Tuenti has gained popularity, mainly because it is a Spanish network focused on Spanish people.

The main advantage is the general purpose of the whole web 2.0 (or social network) concept, the possibility of projecting and exposing one’s own life in the WWW and allowing that way a global exposure (if decided so). Distances disappear  and you can keep contact with friends, colleagues, relatives and you share pieces of your life with them such as videos, or even thoughts, because these networks usually allow you some kind of blogging. In networking terms, you can save the bandwidth of several e-mails sending your holiday pictures just by uploading them to your site on you preferred social network. Basically, the social networking allows you to centralize and organize better your contacts. That can be done with simple e-mails (maybe not the optimum, but it is possible). What’s not so easy to implement in an e-mail system is the concept/benefit of a network: you not only keep contact with your friends or colleagues, but you can extend that contact to your friend’s friend, this way increasing/expanding your own network.

The main risk comes with the missconfiguration on the sites. It is easy for anyone to start your space in these social networks, but not everyone is aware of the proper setup for the desired degree of privacy. This is usually harmless, but you never know when you start sending away data to people you don’t know. Let’s just remember one serious security breach can be done by social engineering, which is the act of manipulating people into performing actions or divulging confidential information about themselves or others. A social network profile can provide that sensible information to anyone without even the need of asking for it.

Are you aware in what ways can your life be exposed?

Fecha Thursday, 26 February 2009

 What would you think if you knew that anyone who you do not even know has access to your entire life? That is likely to be true if you do not take care of your personal details you release onto the internet. 

Of course there are many advantages in using tools such as Facebook or Tuenti. To begin with, these are useful tools to keep in contact with your friends daily. You can add everyone you want to share things with. For example, you show a picture (maybe of yourself, maybe of something related to you) and people you have in your  contact list can leave a comment about it. Also, you can make arrangements with your friends, for instance, what day we get together, or what hour you are going shopping with one of them. In fact, these means of communication can even  replace the use of the mobile phone because is very convenient when you want to meet a group of people. In addition to this, you can see everyone else’s pictures and comments and, therefore, their daily lives. 

However, as in many things nowadays, there are several drawbacks. Anybody can find you and ‘follow’ you through the internet. For instance, an ex-boyfriend is likely to find you and see what you are doing or how you look like at this moment of your life and you do not even notice it. Since the profile of your account may be private, undesirable people can not access to your personal data, but they can see the friends you have, a picture of you…In addition, there may be people you do not like to add to your contact list because you are not close friends, but you feel uncomfortable about not adding them because you might see them later at work. Also, there is an odd situation in where people add you or you add them but later do not even say hello to you. This is ridiculous but in some cases, real. Apart from that, your photos can be used to make a fool of you or showed to people who you do not know. All this without you knowing it! 

So, if you are fond of your privacy, my advice is that you´d better not  try this kind of pages. On the other hand, if you do not mind showing a big part of yourself and, if you want to share things with friends being conscious of the possible consequences of doing that, then you are welcome. By Olga Lopez Iglesias
