Holocaust


Many people argue that Holocaust never happened, with so many information and pictures that everybody views, do you believe that is only a joke?

well...we don´t think so!

Now-a-days exist a lot of traces that show us the real story of suffering of so many people!

German physicians carried out such experiments at Auschwitz, Dachau, Buchenwald, Ravensbrück, Sachsenhausen and Natzweiler concentration camps.
The most notorious of these physicians was Dr. Josef Mengele, who worked in Auschwitz. His experiments included placing subjects in pressure chambers, testing drugs on them, freezing them, attempting to change eye color by injecting chemicals into children's eyes and various amputations and other brutal surgeries.

Photovoltaic painel


The term "photovoltaic" meaning "light", and "voltaic", meaning electric, from the name of the Italian physicist Volta, after whom a unit of electro-motive force, the volt, is named. The term "photo-voltaic" has been in use in English since 1849.

The photovoltaic effect was first recognized in 1839 by French physicist A. E. Becquerel. However, it was not until 1883 that the first solar cell was built, by Charles Fritts, who coated the semiconductor selenium with an extremely thin layer of gold to form the junctions. The device was only around 1% efficient. Subsequently Russian physicist Aleksandr Stoletov built the first solar cell based on the outer photoelectric effect (discovered by Heinrich Hertz in 1887). Albert Einstein explained the photoelectric effect in 1905 for which he received the Nobel prize in Physics in 1921. Russell Ohl patented the modern junction semiconductor solar cell in 1946, which was discovered while working on the series of advances that would lead to the transistor.

The modern age of solar power technology arrived in 1954 when Bell Laboratories, experimenting with semiconductors, accidentally found that silicon doped with certain impurities was very sensitive to light. Daryl Chapin, with Bell Labs colleagues Calvin Fuller and Gerald Pearson, invented the first practical device for converting sunlight into useful electrical power. This resulted in the production of the first useful solar cell with a sunlight energy conversion efficiency of around 6%.The solar battery was first demonstrated on April 25, 1954. The first spacecraft to use solar panels was the US satellite Vanguard 1, launched in March 1958 with solar cells made by Hoffman Electronics. This milestone created interest in producing and launching a geostationary communications satellite, in which solar energy would provide a viable power supply. This was a crucial development which stimulated funding from several governments into research for improved solar cells.
Photovoltaic painel is very usefull to product energy without polluting. Almost all countries are investing in the renovables energy to protect the environment. Besides most of people can´t buy this alternative because it is very expensive and profits are only visible in the long term!

Tânia´s favourite Tv shows


My favorite tv shows are The Simpsons and Grey´s Anatomy. I like very much the Simpsons because many people think that cartoons are only for younger children but isn´t. This cartoons have funny stories and make people laught for briefly.Some times have a moral stories and The Simpsons catches the attention for all people and all ages can see this cartoons.The critically praised series has been bestowed with numerous honors, including recently receiving five Emmy nominations for the 2008-2009 season. Over the course of their two-decade run, THE SIMPSONS have won 24 Emmy Awards: 12 for Outstanding Voice-Over Performance, 10 for Outstanding Animated Program and two for Outstanding Original Main Title Theme Music.The main characters are: Homer, Marge, Bart, Lisa and Maggie.
With the simpsons can also learn more English!!=)

Science Fiction...YES? or NO?

These Movies are so popular because they are the best example of what techonoly is capable to do , what is very fascinating for everyone. The film story is aproprieted for all ages and in most of cases has a love story.
The intencion of technology is capture the people´s attention and create a new world, The Fantasy World!
In this new world happen some things that we don´t see in the reality, but we would like to live it, so it creates an ilusion that makes us keep dreaming.
Usually behind the principal story exist a moral lesson that focus on people´s differences.
We think that kind of films are good, but others don´t because they have a lot of special effects and that turns the movie into a litle fake.

Vampires?just the good ones!


The film Twilight and all books of this saga(Twilight, New Moon, Eclipse and Breaking Dawn) meant that our image of vampires and all the mythical creatures such as werewolves were changed.
This whole saga is really fascinating because it take us to other dimensions where everything is possible. This story is like a dream that we all loved to live.Is an huge sucess between teens because Edward Cullen ( interpreted by: Robert Pattinson)is the person that all girls dream!
It's a Love story between the vampire Edward and the teen Bella (interpreted by: Kristen Stewart)it isn´t the typical story of vampires because these ones don´t need a person´s blood,they drink animal´s blood, they are a kind of "darling vampires".
It's a mixture of our world and the supernatural where LOVE is always the one thing that really matters and the life of a loved one is even more important than our own life!

My favorite movies

My favorite quote


"A dog has no use for fancy cars, big homes, or designer clothes. A water log stick will do just fine. A dog doesn't care if your rich or poor, clever or dull, smart or dumb. Give him your heart and he'll give you his. How many people can you say that about? How many people can make you feel rare and pure and special? How many people can make you feel extraordinary? " John Grogan

Don´t Give Up

forget the shadows of the past
just do what you do
don´t be afraid to try or make mistakes and even if that happens
look to the future with a hopeful smile
because in the end you'll realize that you can always do better!
