Scientific researches include studies on many aspects, such as history, high technology, environment, biology and so on. Any scientific exploration, whether it will result in clear consequence or not, may turn out to benefit our society and life. Thus, government should not decide the devotion to one scientific research merely based on its predictable consequence. In other words, 
It is unreasonable to presumptuously connect one research's value to its possible outcome. Not every study have a certain result, but we may recognize that some researches with uncertainty are worthy and need to be well funded. For example, medical scientists are now finding methods to fight against AIDS, whose treatment has not been completely discovered. Even though the future of this research is unanticipated and we do not know the existence of such methods, it is worthwhile to give hope to the patients as well as other people in the world. As a consequence, researchers are trying their best to do their research on AIDS and the government's auspices are always adequate. On the other hand, researches having clear result may cause some drawbacks. Studies on DNA make it possible that agricultural production has been increased with the innovative transgenic technology. Another creative technique called clone origins some moral issues in the society in spite of its highly noteworthy to scarce species reproduction.
Apart from one research's predictable results, government should take some other factors into account to determine whether or not to invest the research. First and foremost, scientific studies on aviation and aerospace can make a nation more confident on its comprehensive strength, which is fundamental to compete with other nations. In addition, prediction research on some natural disasters, such as earthquakes and tsunamis, are undoubtedly of great value. Although scientists may not find accurate ways to alert an earthquake, they may find probable predictable phenomenons and be aware of the geology and topography of some places where the seismic possibility is higher than other places. Last but not least, the influence one study or invention may have on people's life would also be a significant aspect for the government to consider. Computers intensively improve human's life: we use MSN or Facbook to communicate and share our life instead of face to face chatting, and email turns out to be a more efficient way to send a letter. However, the first computer was designed just to do computing works with lots of data, and people at that time would not know present computers' various amazing applications.
If government do not fund any scientific research whose consequence is unsure and thus not valuable, many scientists will be diffident about their work. They may have many creative but "less worthy" ideas about their research field, which would not be sponsored by government. As a result, many talented researcher will give up their exploration because of no assistance, which is harmful for the development of science as well as the advancement of nations and societies.
Granted that funding some researches with no clear results may result in waste of money and devotion. Nevertheless, such situations are seldom and we can not deny some valuable things appearing in the process of these researches. In conclusion, scientific explorations, whether its consequence is certain or not, may be proved to benefit the researchers' further study as well as our society and life. Thus, it is necessary for government to evaluate a scientific project or research in a comprehensive way, and then decide the amount of its devotion.
