The Professor can always be counted on to email some unusual photos when he's travelling.
Here he is with our dedicated Japanese fan Nagayasu Nawa, who flew several hundred kilometres to meet The Prof in person.
The Japanese school teacher is well-known to Periodic Videos viewers for the quirky gifts he sends to The Professor, some of which have featured in our videos.
On this occasion the gift was a blue “Happi” coat emblazoned with the Periodic Table, of course.
The Professor also sent me this amusing "no drones" sign!
