The Nature of Scientific Discovery
History shows that major scientific breakthroughs rarely happen as single moments of sudden inspiration. More often, they are the result of A____ over many years. For instance, the structure of DNA was not discovered in isolation; it was deciphered based on decades of prior research in chemistry and biology.
Sometimes, an invention emerges B____ to a pressing practical problem. The steam engine, for example, was developed primarily to pump water out of flooded mines. Its creators likely did not foresee that it would eventually power trains and ships, C____ .
An interesting pattern is that similar discoveries are often made independently by different scientists around the same time. This suggests that when knowledge in a certain field reaches a critical point, the next logical step becomes almost inevitable. However, the scientist who receives the credit is usually the one who manages D____ to the academic community.
Ultimately, science is a collaborative and cumulative endeavor. Even the most brilliant mind stands «on the shoulders of giants», E____ .
