Canadian Prime Minister Justin Trudeau is once again causing quite the stir online, after he floored a room full of reporters and academics with his knowledge of quantum computing.
Mr Trudeau was holding a press conference regarding the budget announcement at the perimeter Institute for Theoretical Physics Waterloo in Ontario, when he was caught off guard by a journalist who prefaced his question with a joke about the mathematical jargon written on the blackboard behind him.
"I was going to ask you about quantum computing ..." the reporter said, before moving into a question about Canada's fight against Islamic State.
Without missing a beat or batting an eyelid, Mr Trudeau then spent the next minute eloquently explaining quantum computing and why it is exciting.
"Normal computers work by ... either the power going through a wire or not. It's one or a zero. They're binary systems. What quantum states allow for is much more complex information to be encoded into a single bit. A regular computer bit is either a one or zero -- on or off.
"A quantum state can be much more complex because as we know, things can be both particles and waves at the same time. And the uncertainty around quantum states allows us to encode more information into a much smaller computer.
"So that's what's exciting about quantum computing. Don't get me going on this or we'll be here all night."
The camera then cuts to a standing ovation from some of the audience.
Watch the moment unfold.
