Hi bend. In order to let other people about the things we’ve discovered, scientists write up the results of our experiments and submit them to journals which publish them and send them to scientists all around the world, either physically or over the internet. But the editors of the journals sometimes don’t like the papers we send them: they think the methods are flawed, or they don’t fit with that journal, and they reject the paper. It can be disheartening when you get the rejection email for a piece of work you may have spent months working on. But you just have to keep going, revise the paper so that the next paper you send it to will be more likely to publish it.
My least favourite thing is when an experiment stops working and you don’t know why. It can be really frustrating trying to figure out which part of experiment needs to be changed to get it working again! I used to really hate the maths too, but I’ve got a computer programme that does most of the hard bits for me now so its not nearly so bad! 🙂
