Franklin’s Experiment: How Much Is True?
Benjamin Franklin’s famous lightning experiment has introduced generations of children to science. 1.
The well-known story is that Franklin flew a kite during a storm in 1752. At that time, there was much interest in electricity. People wanted to know if lightning was really produced by electricity. 2. He raised the kite with a piece of string tied to it. A metal key was attached to the string. A flash of lightning hit the kite, and electricity was conducted through the string to the key. 3. This, he said, proved that lightning was a form of electricity.
For years, schools have taught this story and it has inspired us and taught us that scientific experiments are important to establish the truth and to contribute towards later scientific discoveries and inventions.
However, neither the story nor the details of the experiment are entirely true. Although it has been proved that Franklin’s experiment took place, more than one scientist has questioned what really happened. 4. But scientists all agree that if Franklin had actually touched the key, he would certainly have died from the electric shock.
Scientists often question accepted ideas because they want to establish the facts. Some have even questioned the story about the apple that fell on Newton’s head and led him to come up with his theory of gravity.
5. But in science, facts should be proved by experiments and research, and we should not always believe everything we read or hear — even if it is a great story.
A.Franklin was one of them.
B.The detail about the string and the key is true.
C.It’s true that many discoveries start with an experiment.
D.Admittedly, fiction is often more interesting than the truth.
E.Franklin then touched the key with his finger and got an electric shock.
F.However, new research suggests that the story may be fiction instead of fact.
G.This experiment proves beyond any doubt that lightning is an electric phenomenon.
[1] I was interested in different science fiction ideas and technologies. But there is one theme in science fiction that has always troubled me: when technology subverts (颠覆) its creators.
[2] I’ve been involved in dozens of technology projects. I have to admit that seldom in our design or business discussions have we spent much time on the possible negative impact of our work on the world. Instead, in most cases we just create technology because we see a need, or to solve a problem.
[3] Technology has been responsible for an age of distraction. Recently while driving from northern New York City to the Elmira area, I saw signs saying, “Next texting stop is three miles ahead. Don’t text and drive.” Most states have already outlawed texting while driving, and yet we hear almost weekly of traffic accidents caused by drivers tapping on smartphones. I don’t believe Steve Jobs and Apple dreamed that the iPhone, or smartphones in general, would give rise to this level of distraction.
[4] In a recent Harvard Business Review piece entitled “Liberal Arts (人文科学) in the Data Age,” the author writes about the importance of reconnecting humanism with engineering approach. Many of today’s engineers have been so focused on creating new technologies that their short term goals risk covering up unintended long-term outcomes. A few companies, such as Intel, are forward-thinking enough to include ethics (伦理学) professionals on their staff. At this point all tech companies should start getting serious about the need to hire people with backgrounds in areas such as psychology and philosophy (哲学).
[5] My hope is that we can all move a little more in creating technology that is both impactful and thoughtful in its engagement with our lives and the world.
