Using the Hubble Space Telescope

The latest video on Sixty Symbols features Dr Meghan Gray discussing how the Hubble Space Telescope is maneuvered.

But perhaps equally interesting is the "extra footage" posted to the nottinghamscience channel, in which Dr Gray discuses her own experiences using Hubble on the STAGES survey. The relevant section starts from 1 mins 37secs.

Also wanted to share a bit more about this photo, which appears in the video and was used with thanks to Iain Strachan.

It shows the Trinity Mathematical Society in 1938, and the key people in the picture for the "squaring square" video are Brooks, Stone, Smith and Tutte.

Mr Strachan came across the picture via his late uncle, Frederick C. Strachan, who is also shown.

Mr Strachan shared the following family story about his uncle.

"He was a very bright mathematician - according to his school (Taunton School), the best the school ever had.  He had a free place at Trinity.  My Dad, Norman Mervyn Strachan, also got a place at Trinity to read maths, but not a free place.  Unfortunately, his parents didn't have enough money to send him, plus the war was coming soon, so Dad joined the Home Guard, and eventually became a Captain in the Royal Corps of Signals. 

"Freddie also became an officer in the Royal Corps of Signals (1st Lieutenant).  A favourite story in the family was when he was interviewed by a Colonel, initially for the Royal Artillery.  The Colonel looked at his application and said 'Hmm I see you have a double First Class Honours degree in mathematics from Cambridge'.  'Yes' says Freddie.  The Colonel replies '... I suppose that would include trigonometry?'

"That story got repeated at Freddie's funeral (he died at the age of 94).

"I am somewhat surprised Freddie didn't get recruited by the GCCS to Bletchley Park, like Tutte - he was also a whizz at crosswords.  But he graduated in 1938 and got a job as a patent examiner before the war started, and continued in that career afterwards."

The Complete Collection of Incompleteness

Gödel's Incompleteness Theorem has been one of the most requested videos on Numberphile.

The task of explaining it was taken up by none other than Professor Marcus Du Sautoy (a household name in the UK, at least when it comes to mathematics!)

We posted three videos - a main explanation plus two lots of "extra footage" .

Neil wins President's Prize

Anyone who watched Periodic Videos will know the importance (and cult hero status) of Neil Barnes.

Neil is a senior technician in the School of Chemistry at the University of Nottingham.

Neil Barnes - Senior Technician.

Since we started making videos, Neil has been the guy who sets up, carries out and cleans up most of the experiments.

But what you do not see on camera is that Neil is also a key part of coming up with ideas and planning the whole process.

When I'm not around, Neil spends many hours plotting future videos, dreaming up new experiments, and building devices to make them possible.

This week Neil was recognised for his role with the Royal Society of Chemistry President's Award.

Professor Sir John Holman, president of the Royal Society of Chemistry, said: “Neil brings together two things that are very important to me personally... 

"The first is technical skills. Skilled technicians are vital for the success of the chemical sciences and Neil has shown their importance as a research technician in physical chemistry at the University of Nottingham.

"The second is outreach: as chemists we all need to do our bit to inspire the next generation of chemical scientists, and Neil has helped bring the excitement of chemistry to thousands of young people around the world by supporting Sir Martyn Poliakoff so expertly with his brilliant Periodic Videos.

“For me it feels just right to be presenting this award to Neil Barnes who has brought these two priorities together so fittingly.”

Jonathan Hirst, Head of the School of Chemistry, said: “Our technical staff are the cornerstone of much of the School’s activity. Neil has supported and inspired many students and colleagues in the School, and much more widely through social media.”

Professor Poliakoff said: “Neil is a key person in the success of our videos.  His enthusiasm, knowledge of chemistry and silent acting skills have made him a super-hero of chemistry.  He is an excellent ambassador for chemistry, for Nottingham and for the role of University Technicians.  And he is fun to work with!”

The Maestro

Alan Stewart - or "The Maestro" as I like to call him - has released a new album of piano music.

Hanging out with Alan

Hanging out with Alan

Alan is an England-based physics teacher, but also a talented musician who has helped with my videos for many years. See some examples below.

(He's also the creator of Hello Internet's short "theme tune" that plays at the start of every episode)

The new album is called Sunsettlement - and Alan has posted it to YouTube.

But I'd also really encourage you to consider it on Spotify, Apple Music, iTunes, GooglePlay, Amazon, et al.

It's well worth your time - but also a great way to show some support for a great guy.

I listened to the whole album (twice) on a recent long-haul flight, and loved it.

To remind you of my work with Alan, here are some videos he contributed to:
