Can we trust the internet for our knowledge or even for our research things?
Not all materials on lessons learned from the internet is true. Likewise, the news is presented in such apparently, that laypeople be a genius suddenly.
All that served the Internet sometimes makes people believe their science minimally.
Actually textbook still the main source in some science projects, because they are still using the bibliography and references, while the Internet that presents information as it should be paid.
Who says the internet is an incredible science?
Sometimes the internet was even misleading, some people who frequently write material science would not be responsible for what they writes when others lost.
Unless a material science presented already by editors who know the exact source of knowledge is given, the relevant bibliography and references are correct.
