Question

Scientists have to work very hard and make many sacrifices for years, to achieve success in their experiments. Why?

Answer 1

A scientist has to search and discover new information and knowledge from zero. She/he has to create an experiment, decide what tools and materials will be needed, and sometimes make the tools or materials that are not available. Experiments may not always work or give results. One has to keep trying, without being sure of the desired result. Edison made 1000 failed attempts before he invented the consistent light bulb. It takes years of constant efforts, determination, and sufficient resources to achieve success in experiments. Hence, scientists have to work very hard and make many sacrifices for years, to achieve success in their experiments.
