Some things seem to be a given. Everybody should have solid computer skills and a good knowledge of English to be able to do science today. Technology gives us access to information and various means of really fast communication; English has become the universally used common language in any sphere of human activity. Information and communication, exchange of ideas and cooperation allow science and research to move forward at unimaginable speeds. When you are doing research in one field, naturally you need to keep track of what others are doing, to be cognizant of the things done in various countries. An important part of any good researcher’s work is reading the relevant publications. Another one is attending conferences and talking to colleagues. Suppose you read about a group which managed to synthesize certain catalysts. You can envisage them being useful in your own experiments. So you contact the researchers in question and thus an exchange and cooperation may start. Once your experiments are done, you may publish your results, naturally giving credit where credit is due. Then you may be contacted by people from a rather different field who find your experiments useful in their own research, and yet another thread starts. Eventually you may find yourself or your group or lab connected to groups in different countries, and the results you may obtain may surpass anything any of the participants could anticipate. So an article about this great collaboration may be written by about a dozen people. It does not mean that all those people will continue doing this type of work in the future. They may all move in different directions and eventually branch off into completely separate fields. Yet the connections, the collaborations and the human contacts remain.
Besides your own branch of science, some other things never stop. Technology develops so fast that one person cannot do everything, master all the new skills. One should continue studying,,picking up the new skills, mastering the new devices and using the new programs. If you find your language skills lacking, just keep up your studies. Read, listen, watch and communicate whenever you have the opportunity to do so. When in doubt, ask. Nobody will think the less of your physics or chemistry knowledge if you happen to make a grammar mistake in English or if you are unfamiliar with the latest developments in tweets. I am pretty sure that any discovery in any science needs a lot of work. When you obtain significant results, the next stage is being able to share so that others understand what you are doing.
