I have been working on a scientific paper today.
I obtained very important experimental results, and another professor simulated the results by computation.
It has become a very beautiful paper.
We decided to submit it to a famous, prestigious journal in that area. It is my first time to try the journal.
Since the journal is of a high class, they (arrogantly) demand many details of the format. Therefore, I have been checking and modifying the paper.
It is almost done. I will submit it tomorrow.
