There are many ways to bring science to the public, and the University of Helsinki awards its researchers for their efforts to do so with the annual J. V. Snellman Award. Professor Samuli Siltanen, who has won this year’s award for popularising scientific research, is known as a charismatic performer who often tours schools to talk about mathematics.
“My best audience is definitely in the schools, particularly when there are both upper- and lower-secondary school pupils in the room. Those are the events where they ask the best and most difficult questions,” he explains.
How is it possible that Siri or navigators can talk to us – this is the kind of question Siltanen may tackle in class. He may then discuss good and bad machine speech with the help of one of his latest
YouTube is a favourite in disseminating research information to the public
To Siltanen, the best way to present science is through live performance, as it allows for interaction with others. His second favourite option is video. Siltanen’s YouTube channel,
This delights Siltanen, whose work centres on the visualisation of information.
“In my own field, the mathematics of medical imaging, finding a visual approach is fairly easy, but it’s usually not too difficult to do for other fields of mathematics either. I can’t use formulas, which is of course terrifying to a mathematician,” he says.
“On the other hand, it’s not like musicians perform by holding up sheet music – they just play. That’s the real music.”
Scientific information is reliable
When asked why science communication is necessary, he returns to the fundamentals: Research uses up a great deal of public funding, and for that reason alone, tax payers have a right to hear about its results in a way that they can understand.
“Since humanity has laboured so much to produce the scientific method to find things out, everyone should be aware of it. The scientific method is the most effective and reliable way of generating information. Particularly during our ‘post-truth’ era, it’s good to remember that scientific information is the most reliable information we have.”
He also points out that making scientific phenomena approachable also attracts new scientists to the field. That is also important!
