WHY DID THEY NOT DO SO ?
A question that every researcher should ask, after having looked for a huge amount of information, which are related to a specific problematic.
Inventions, either in exact or human sciences, are always the result of a research, done by reading publications, watching documentaries, doing investigations, comparing results, making analysys...and so on!
In a specific stage of a study, the researcher can make a comparison between the different learned informations, from which he may deduce: If I do so, the result would change and be better :)
Why did they (the predecessors) not do so?
The simple answer to this question is: because Allah's destiny wanted YOU specifically to be named the inventor ;)
Conclusion: any researcher may bring something new to this life, just by trusting his ability in concluding a solution from a big research he/she should do ;)
