Cellphones: is there a cancer link?
Could your cellphone give you cancer? Whether it could or not, some people are worrying about the possibility that phones, power lines and wi-fi could be responsible for a range of illnesses, from rashes to brain tumors.
Some say there is evidence to support the growing anxieties. David Carpenter, a professor of environmental health sciences at the university at Albany, in New York, thinks there’s a greater than 95 percent chance that power lines can cause childhood leukemia(白血病). Also there’s a greater than 90 percent chance that cellphones can cause brain tumors. “It’s apparent now that there’s a real risk,” said Carpenter.
But others believe these concerns are unjustified. Dr Martha Linet, the head of radiation epidemiology(流行病学) at the US National Cancer Institute, has looked at the same research as Carpenter but has reached a different conclusion. “I don’t support warning labels for cellphones,” said Linet. “We don’t have the evidence that there’s much danger.”
Studies so far suggest a weak connection between EMFs(电磁场) and illness — so weak that it might not exist at all. A multinational investigation of cellphones and brain cancer, in 13 countries outside the US, has been underway for several years. It’s funded in part by the European Union, in part by a cellphone industry group. The final report should come out later this year, but data so far don’t suggest a strong link between cellphone use and cancer risk.

The literal meaning of philosophy is “love of wisdom”.But this meaning does not tell us very much.Unlike the other disciplines(学科),philosophy cannot be defined by what you study,because it is actually unlimited.Anything can be the subject matter of philosophy: art, history, law,language,literature,mathematics,medicine,psychology,religion,science,and values.Philosophy is one of the world’s oldest subjects of study,and in fact,the other academic disciplines are directly related to philosophy.For this reason you get a Doctorate(博士学位) of Philosophy(Ph.D.) in biochemistry,or computer science,or psychology.
Two broad sub-fields of philosophy are logic and the history of philosophy.Logic is the science of argument and critical thinking.It provides sound methods for distinguishing good from bad reasoning.The history of philosophy involves the study of major philosophers and period in development of philosophy.
Of what use is philosophy?First it is useful in educational advancement.It is necessary for understanding other disciplines.Only philosophy questions the nature of the concepts used in a discipline,and its relation to other disciplines.And through the study of philosophy,one develops sound methods of research and analysis that can be applied to any field.
There are a number of general uses of philosophy.It strengthens one’s ability to solve problems,to communicate,to organize ideas and issues,to persuade,and to take what is the most important from a large quantity of data .These general uses are of great benefit in the career field,not necessarily for obtaining one’s first job after graduation,but for preparing for positions of responsibility,management and leadership later on.It is very short-sighted after all,to take a course of studies only for the purpose of getting one’s first job.The useful skills developed through the study of philosophy have significant long-term benefits in career advancement.No other discipline systematically follows the ideals of wisdom,leadership,and capacity to resolve human conflict.
