Scientific research and government funding
While I can see that it is unnecessary to publicly fund some truly useless scientific exploration, it would be an exaggeration to claim that all research without immediate practical use deserves no government support.
On the one hand, government funds are limited and they come from taxpayers. Therefore, public money should normally be prioritized for projects that can bring immediate benefits or tangible benefits to the public. Some research projects may not have any clear connection with citizens' daily lives in the short term. For example, research into distant planets may be unlikely to improve ordinary people's lives immediately. In this case, it may not be fully justifiable for the government to spend a large amount of taxpayers' money on such projects.
Moreover, this does not mean that such projects deserve no funding at all. Some of them may be supported by private institutions or individuals who are personally interested in the research. For instance, research into fatal diseases in dogs may attract support from dog owners who are willing to save their pets' lives. In this process, the government does not necessarily have to provide financial support; it can instead help by pushing through relevant legislation or approval procedures.
On the other hand, some research only seems impractical in the short term, but it may be of great use in the long term. Research into genetic modification, for example, may once have seemed impractical, but long-term scientific endeavors have contributed to the development of target drugs today. Similarly, some mathematical research may not bring direct profits at first, but it can later become the foundation of technology in engineering, computer science or encryption.
Another reason for government funding is that private support may not be sustainable enough. Some research has a long temporal lag: the money invested today may not produce useful results until many years or even generations later. Individual donors or private organizations may lose interest, run out of money, or fail to continue the project for a sufficient length of time. A stable government, by contrast, can continue to support valuable long-term research.
Four London airports pie charts
Overall, business was the dominant purpose of travel for passengers at all airports except Gatwick Airport, where the predominant purpose was to visit friends or relatives.
Regarding the other three airports, business was the primary purpose, with the percentages standing at around a half. Another common purpose of travel was visiting friends or relatives, while holidays ranked third. The figures should be presented in a clear order, and respectively can be used when several airports and several percentages are matched one by one.
By contrast, at Gatwick Airport, visiting friends or relatives was the most common purpose of travel, while business followed behind. In this type of static pie chart, others does not usually need to be emphasized in the overview because it is often only used to complete the total percentage.
