TEXT
The search for life beyond Earth
We have always been fascinated by the thought of alien life elsewhere in the universe. The idea has provided the basis for a huge wealth of science fiction stories that have been limited only by our imaginations. But can other creatures exist in the vast reaches of space or on other planets or moons? And are there other intelligent forms of life out there—or are we more likely to find something much simpler?
Where are all the aliens?
Our Sun is just one star among billions in our galaxy. In the last few years, scientists have detected thousands of planets around other stars and it seems that most stars have planetary systems. It’s therefore likely that there will be large numbers of habitable planets in the Milky Way galaxy and beyond that are capable of supporting intelligent life. Some of these intelligent civilisations, if they’re out there, may have even developed interstellar travel.
Are there other intelligent forms of life out there—or are we more likely to find something much simpler?
But Earth hasn’t been visited by any intelligent aliens (yet?). This apparent high probability of life, combined with a lack of evidence for its existence, is called the Fermi Paradox, named for the physicist Enrico Fermi who first outlined 1 the argument back in 1950. This begs the question: where is everybody?
Back in 1961, astronomer Francis Drake tried to rationalise this question by developing an equation that takes into account 2 all the factors relevant to finding alien civilisations and gives an estimate of the number of civilisations out there in the galaxy that should be able to communicate with us. It considers factors such as the rate 3 of new star formation, how many planets around those new and existing stars might be able to support life, the number of planets supporting intelligent life, how many of those civilisations might have technology we can detect, whether they’re likely to communicate with us here on Earth, and so on.
The search for extraterrestrial intelligence
Scientists and radio astronomers have started the search for extraterrestrial intelligence (SETI) in a systematic manner. Several international organisations, including the SETI Institute and the SETI League, are using radio telescopes to detect signals that might have been produced by intelligent life.
In 1995, the SETI Institute started Project Phoenix, which used three of the most powerful radio telescopes in the world: the Green Bank radio telescope in West Virginia, USA; the Arecibo telescope in Puerto Rico; and the Parkes radio telescope in NSW, Australia. During its initial phase, Project Phoenix used the Parkes telescope to search for signals coming from 202 Sun-like stars as distant as 155 light years away. By the end of its operations, Project Phoenix had scanned a total of 800 ‘nearby’ 4 (up to 240 light years away) stars for signs of life. The project detected some cosmic noises, but none of that could be attributed to aliens.
These days, anyone can become involved in the search for extraterrestrial intelligence through their personal computer.
While there’s currently excitement about sending human crews to Mars, missions beyond the Red Planet are at this stage pretty much not feasible 5 the distances and travel times involved are simply too great. Basically, all exploration for life beyond Earth will need to be done using robotic space probes 6 and landing rovers. These instruments can provide a huge wealth of information and are capable of exploring as far away as Pluto, perhaps even beyond our solar system. But as for life beyond the solar system, the nearest stars are several light years away, and even communications by electromagnetic waves (which all travel at the speed of light) are essentially going to be a one-way message.
While we probably won’t find intelligent life too close to home, there’s a chance we may still find much simpler life forms. Do we have neighbours beyond Earth? Time will tell—and the search continues.

Para dinamizar suas aulas no 8o ano a professora Luíza organizou um jogo distribuindo duas fichas contendo operações com os números reais.
Dois alunos participaram da 1ª rodada do jogo: Lucas e Mateus.
Ao jogarem, esses alunos receberam as seguintes fichas:
Aluno Ficha 1
enunciado 2072250-1 !$ A = \left [ { \Large { 0, \bar{7} + \large { 2 \over 9} + \left ( { \large 5 \over 4 } \right)^0 \over -0,5 - 4^{ \large 3 \over 2} – 2^{-1}}} \right ]^{-1} !$
enunciado 2072250-2
!$ C = { \Large { \left ( 0,333 \cdots \right)^3 \cdot 1 \large { 4 \over 5} + 2,2 \over -1,1333 \cdots}} !$

Ficha 2
enunciado 2072250-3 !$ B = { \Large { 8^{0, \bar{6}} + 4^{ - \large {3 \over 2}} – 2^ { \sqrt{9}} + 9^{0,5} \over - \left ( { \large 1 \over 49} \right)^ { - \large {1 \over 2}}}} !$
enunciado 2072250-4 !$ D = \left [ \left ( \left ( { \large 1 \over 6} \right)^{-3} \cdot 0,\bar{6} \right )^{ \large 1 \over2} + \left ( \left ( { \large 2 \over 3} \right)^0 – \large { 1 \over 1,33 \cdots} \right )^{ \large 1 \over 2} \right ]^{- \large { 1 \over 2}} !$
Depois de resolverem as operações, cada aluno deveria associar corretamente os resultados obtidos em cada ficha a somente um dos conjuntos abaixo.

TEXTO II
Ladainha II
Por que o raciocínio,
os músculos, os ossos?
A automação, ócio dourado.
O cérebro eletrônico, o músculo
mecânico
mais fáceis que um sorriso.
Por que o coração?
O de metal não tornará o homem
mais cordial,
dando-lhe um ritmo extra-corporal?
Por que levantar o braço
para colher o fruto?
A máquina o fará por nós.
Por que labutar no campo, na cidade?
A máquina o fará por nós.
Por que pensar, imaginar?
A máquina o fará por nós.
Por que fazer um poema?
A máquina o fará por nós.
Por que subir a escada de Jacó?
A máquina o fará por nós.
Ó máquina, orai por nós.
(RICARDO, Cassiano. Jeremias sem-chorar. Rio de Janeiro: José Olympio, 1964.)
Analise as afirmativas feitas em relação à composição e interpretação do texto II.
I. O texto pode ser dividido em duas partes: a primeira representa dúvidas do homem moderno em relação a si mesmo. A segunda, a sua impotência para respondê-las, que o leva a um comportamento subalterno marcado pela ladainha em louvor à máquina.
II. A máquina é criticamente equiparada a um deus, já que é capaz de fazer tudo para e pelo homem, e, dessa forma, é reverenciada através de uma oração, como se fosse uma divindade.
III. O texto é marcado por uma contraposição entre homem e máquina, tendo esta a supremacia sobre aquele, tanto que o faz desprezar-se a si mesmo e a orar para ela.
IV. A terceira estrofe do poema é construída por meio de uma gradação que representa as atividades humanas substituídas pela máquina, desde as mais simples até as mais apuradas.
Estão corretas as afirmativas
