Great pleasure to meet and interview astronaut Tim Peake at the Johnson Space Center, in Houston.
Interview part one:
British Tim is due to fly to the International Space Station in December, on his Principia Mission.
Pics from the interview by Destin Sandlin.
Two videos to mark the New Horizons probe passing (and snapping) Pluto.
From Periodic Videos, a look at the role of Plutonium.
And some fun chat from the crew at Sixty Symbols (grain of salt recommended).
And here are some other related videos from the archive.
Recently I heard from a video viewer and podcast listener called Valia.
In part, her email said:
"A year and a half ago, when you first talked about your visit to the Royal Society in one of the early podcasts, I was in my home country unsure of what I wanted to do and a little bit confused about my future plans. Listening to you talk with such enthusiasm about the Royal Society made me research their history and policy and become inspired by their vision. Fast forward to today, I have moved to the UK and will be volunteering at the Royal Society Summer Science Exhibition this coming week."
A week or two later, Valia email again with pictures from the exhibition.
I can't help noting she also was flying a flag.
Valia concluded:
"Thank you again for being the catalyst for this incredible experience. In the future, every time I watch the Objectivity videos, I will do so with a huge smile on my face."
Here's an example of Objectivity, filmed at the Royal Society:
And here's Grey and I doing Hello Internet at The Royal Society:
Superb portrait of Keith Moore (Royal Society library boss and star of Objectivity) by Chris Stern.

Fitting for a man who spends a lot of time around portraits.
This week we posted a Numberphile video about a mysterious drawing by John Herschel, contained in a letter to his friend Charles Babbage.
Herschel challenged Babbage to "interpret this hieroglyphic, it contains a great discovery."
A devil-like figure, surrounded by complicated squiggles and equations, was captioned as "Dionysius the God of Functions, alias the genius of numerical magnitude".
Numerous viewers have shared their theories about what it may mean.
But the most promising I've seen so far came from user david getsout who said:
"Back in the day dionysius lardner was a professor at london working with hershel to build big telescopes dionysius would talk shit about the infinate universe and us being at the center due to human perception or somthing complicated like that."
(SIC)
I had never heard of Lardner, but some quick Wikipedia and Googling shed more light on matters.
Lardner sounds like a science populariser and commented/lectured on the work of people like Babbage and Herschel.
I can easily envisage two scientists being a bit snarky toward someone who does that. It is not uncommon these days!
Was Herschel (left) mocking Lardner (right)?
It may also explain why Herschel spells it Dionysius with an "i" and not Dionysus which is how the God of Wine is spelled? But I don't know much about the history of this word.
I look forward to more investigative work by keen-eyed and clever viewers.
As discussed on Numberphile, here is John Herschel's doodle, sent to his friend Charles Babbage.
Herschel said: "Interpret this hieroglyphic, it contains a great discovery."
The figure at the centre is described as: "Dionysius the God of Functions, alias the genius of numerical magnitude."
Just silliness between two friends, or something more?
