There aren't too many events that link body mass index, champagne and TV series Breaking Bad.
But all three subjects are among the attractions at this year's TechFest in Aberdeen.
The city's annual festival of science, technology, energy and mathematics, is preparing to explore the mysteries behind BMI and body fat, the science behind one of the world's favourite tipples and examine the weird world of TV anti-hero Walter White.
The first of these thought provoking events is Demystifying BMI and the Truth About Fat, will be hosted by Dr Saleyha Ahsan, at Robert Gordon University on Sunday, September 13.
Dr Ahsan is a practising A&E doctor, former captain in the Royal Army Medical Corps and is most famous for co-hosting the hit series, Trust Me I’m A Doctor.
Her presentation will look at the controversies behind BMI measurements and the truth about fat.
The second event is hosted by Adrian Gomes of local business, 10 Dollar Shake, who will guide attendees through a tutored tasting of champagne, discussing production techniques and food pairing suggestions.
Science of Champagne will take place on Monday, September 14, at Rye and Soda in The Academy.
It's just another strand to the eclectic mix at the festival, which runs from September 11 to October 2, and is set to attract tens of thousands of people to a series of fascinating workshops, presentations and events.
Sarah Chew, managing director of TechFest, said: “Dr Ahsan is hugely respected in her field and her talk promises to be hugely stimulating.
"Diets and the food we eat are of huge interest at the moment and I’m sure she will shed some light on a very interesting subject.
“We are delighted to be able to work with Adrian and his team to deliver this Champagne workshop, which I’m sure will appeal to everyone who likes a glass of bubbles.
“We have introduced a number of new events and venues this year and the public programme offers something for all different age groups and audiences, from the fun and light-hearted to high level presentations on topical subjects.
She added: “We are indebted to the assistance we receive from all our sponsors and supporters, in particular our joint principal sponsors Shell and BP, whose ongoing backing helps us to continue to educate, inspire and entertain.”
Other key highlights include The Science of Breaking Bad, Hollywood Science, The Ugly Animal Roadshow and the closing event with Miranda Krestovnikoff.
