Engineering with Atoms

26 years ago, in 1987 I made a promotional video for the Department of Materials. It had a slightly grander title that usual, “Engineering with Atoms: Materials, Science and Engineering at Imperial College”. Once again this video is a treasure of scenes and images of life at Imperial College in the mid 1980’s. And, as with most promotional videos that we made, it contained a large amount of ‘stock footage’ from previous videos and some of this is now notable because of the vast changes that have taken place on the South Kensington campus.

As with all promotional videos an enormous input was required from the actual department in terms of what they needed to say and to show. Getting the words right is vital, so from the department I was aided by colleagues: Kilner, Rawlings, Flower and Walker. The latter two also provided the male and female voice-overs heard on the video. Harvey Flower is notable because of his tragic death in April 2005. He’s also seen in one sequence sitting at an electron microscope and later on he’s standing with his colleague at a departmental party.

Other worthy mentions are Princes Gardens with its old layout design and masses of colourful summer flowers, along with the original halls of residence. Also making an appearance are the 1960’s frontage of buildings facing onto Exhibition Road; the walkway and JCR. Making it into the video as well is the old swimming pool and tennis courts (located where the new Eastside Halls now stand). I’m fairly certain that the departmental library would have been merged into the central library, so shots of that in the video are also a record of daily life in the department. In fact the whole video is a snapshot of what Imperial College was like in 1987 and a true Video Archive post if ever there was one!

The usual tape problems occurred with the digitisation of this video, so any slight glitches or jumps are due to those problems. As always, if you are seen in this video please do let us know where you are now and what you are doing. Use the reply box below to make contact with me.

Bob Spence, still going strong at 80

I have rediscovered a fascinating interview with Professor Bob (Robert) Spence, Professor Emeritus of Information Engineering & Senior Research Investigator in EEED. Today, Bob turns 80 and what better way to help him celebrate than bringing to your attention this interview from 1994. At the time, the TV Studio was still in operation and I was making a monthly video for a computer company called Lantec. A former TV Studio colleague of mine, Steve Bell, who worked for Lantec, asked me if we would make these videos for distribution to their company clients. The result was a programme we called Video Interface. This video is from Edition 13, from December 1994 and Steve is talking to Bob about his research work. I take no credit for the remaining text below, as it comes from Bob’s own personal web page at Imperial. I have added however a few links to videos I made with Bob on some of the subjects mentioned.

Bob’s research has ranged from engineering design to human-computer interaction and often with the manner in which the latter can enhance the former. Notable contributions, usually in collaboration with colleagues, include the powerful generalized form of Tellegen’s Theorem; algorithms for improving the manufacturing yield of mass-produced circuits; and, in the field of Human-computer Interaction, the invention of the first focus+context technique, the Bifocal Display (aka Fisheye lens). The novel Attribute and Influence Explorers provide examples of novel information visualization tools that have wide application, including engineering design. Interactive computer graphics allows the electronic circuit designer to sketch the familiar circuit diagram on a computer display. This potential was pioneered by Bob and his colleagues in the late 1960s and eventually, in 1985, led to the commercially available MINNIE system developed and marketed by a company of which Bob was chairman and a founding director. More recently, Bob’s research has focused on the topic of Rapid Serial Visual Presentation in which a collection of images is presented sequentially and rapidly to a user who may be searching for a particular image. This activity is similar to the riffling of a book’s pages.

 

spence 51 yearsAnd yet more news about Bob in April 2014 is that he has now achieved 51 years of service at Imperial College. See this article and scroll down to read about it. In the article Bob says “I’ve always said that if something is fun, it’s worth doing – and I’ve certainly had a lot of fun over the past 51 years.  Imperial has always had a fantastic community, and it boasts some exceptional students. They are the reason I continued to teach after my retirement – I never tire of working with them….”

Honda Wind Tunnel Opening July 1985

28 years ago today on July 8th 1985 a project between Imperial College and the Honda Automobile Company was celebrated with the official opening of the new Honda Wind Tunnel in the Department of Aeronautics.

The Aeronautics Wind Tunnel today

Earlier in that decade the Honda company had approached the college and offered to pay the costs of the construction of a large wind tunnel. It transpires that Honda were trailing behind competitors in their car design and needed help. They offered to pay the construction costs in return for the testing of car models and the training of staff in wind tunnel technology. Professor Peter Bearman from Imperial College oversaw the design and construction, he can be seen towards the end of the video. Former Rector the late Lord Brian Flowers makes the initial presentation, followed by the then head of the department, Dr Glyn Davies. The design and construction created, at the time, one of the world’s largest wind tunnels. The contract with Imperial College was also one of the biggest between a Japanese automobile company and an academic institution.

The tunnel was opened by Mr Fujio Ishikawa, Senior Managing Director of the Honda Motor Company. You can read a full page article about the wind tunnel in the Imperial College student newspaper Felix dated 17 May 1985, scroll down to page 6 on the PDF.

Imperial’s external TV view

Over the years, many film and TV companies have come to Imperial College. I recall regular visits to the South Kensington campus by BBC TV’s “Tomorrows World” and in some cases I watched them at work. But these visits have all disappeared with no record retained by the college. This is a great shame because these are part of the history of Imperial, its staff and more importantly its research.

But there is just one item that was retained in the archives. Although it doesn’t have any form of introduction titles, it was made, (I think) by the Central Office of Information in about 1969. I certainly remember the filming of the opening and closing sequence. If I am correct then this is one of several identical films shot in a series called “This week in Britain”. Identical because they were all made in several languages at the same time. And judging from the accent, this one was for Australia (ABC perhaps?). I certainly remember one of these visits to the lab of Eric Laithwaite where several women in different colourful outfits each did the same introduction, one after the other, but in their own language.

The film that we do have shows some interesting research being carried out around the college at that time. You’ll see the original Civil Engineering Hydraulics Lab; a brief example of Eric Laithwaite’s linear motor research; Alan Swanson demonstrating his artificial knee joint replacement;  the wind tunnel in Aeronautics and finally Chemical Engineering’s Plutonium work. Were you in the Mechanical Engineering workshop when they filmed in there, if so you might spot yourself? The introduction and closing was shot on level 3 of Civil Engineering. And if you remember the college from the 1960’s you will also spot the distinct style of the signs on the old walkway.

Finally, I love the phrase used at the end where Imperial College is called “Science City”, a term I have never heard! Maybe we should start to use it?

Chemistry Teaching Videos: 1981-1993

If you were studying Chemistry at Imperial College in the early 1980’s you would almost certainly have come across the series of teaching videos that we made. These were designed to provide a single definitive version of classic experiments carried out in the labs.  The way that it worked was that during a lab period students would have a number of ‘demonstrators’ who positioned themselves around the lab. They would then proceed to show the undergrads the way to achieve what was needed of them during the session. This was deemed to have flaws when it was discovered that very slightly different versions were actually being demonstrated. So, colleagues in the Chemistry Department asked for some of the experiments and also the techniques required, to be captured on video. These videos would then be made available to the students in the college library, prior to the lab session day and also at the start of the actual lab session via video players located around the lab. Starting 32 years ago, from 1981 to 1993,  11 of these classic experiment videos were made. Two of these: ‘Recrystallisation’ and ‘Using an Oil Vacuum Pump’ are on this page.

Making them was not always so easy. To capture the experiments we needed to be able to record, as much as possible, in ‘real time’. That is, record the action without stopping or having to then edit later. We needed to be able to try and capture what would have been demonstrated live in the lab. Also, when an experiment had started, it couldn’t always be stopped on a whim from me because I couldn’t get a good camera shot! So, we had to be able to record with several cameras and this meant shooting in the College TV Studio** where we had three cameras available. Shooting this way meant we could, as much as possible, run in real time; if we had rehearsed what was going to happen. So, using three cameras we were able to plan ‘blocks’ of the experiments that could be recorded before we had to stop and reset cameras etc

 

 

Chemistry in a TV Studio has its problems though. And one of THE biggest problems was with white lab coats. Our early colour cameras had a single stripe vidicon tube in them and the bright white labs coats were susceptible to almost glowing in the end result shot . The light required for good pictures was a little higher than for black & white and highlights would very easily burn out, a good example being the glassware. The three cameras also had manual adjustment for colour, so getting all three to give well balanced images, all the looking same, was a nightmare at times! Another problem was ensuring that I could see on the monitors what was required, without a hand or shoulder blocking the view. We tended to position a monitor so that the person demonstrating could see whether or not this was happening. It was easier for them to move than for the cameras to do so.

 

After 32 years some of the videos are starting to show their age and playback is becoming difficult. It took a few hours before I could get a stable playback I was happy with, in order to transfer them onto DVD.
If you studied Chemistry and came across these teaching videos during your course then please do let us know via the comment option below.

** Even though we are now in a “YouTube video age”, sadly in February 2007 Imperial closed the TV Studio, along with its Control Room, Editing Suite and also the Video Conferencing Service. The videotape archive remains within Communications.

Post Graduate Ceremony 2009 – Presentation of the Mace

As we celebrate yet another Post Graduate Ceremony (May 2013) I thought we would look back only a few years ago to 2009. This was the year that the Imperial College gained its own Mace and it was officially presented to the college during the ceremony at the Royal Albert Hall in May of that year. The mace is the generous gift the Goldsmiths’ Company, who have had a long association with the College. It was given to mark the designation of the College as a university in its own right and the award of a new charter by the Queen. The Goldsmiths’ Company commissioned Padgham and Putland of Kent to design and construct the mace. The mace weighs 7.1kg and is of silver and gilt. Its intricate workings incorporate the College crest and motto. The video is part of that May 2009 ceremony at the Royal Albert Hall, London.

Lord Kerr was still Chairman of the Governing Body at that time and he accepted the gift on behalf of Imperial College London.

Margaret Thatcher at Imperial College: 1985

In a previous entry you would have seen the video I made to celebrate the City and Guilds College Centenary in February 1985. As part of the week of events an exhibition was run entitled “Technology 2000”. It was opened by Margaret Thatcher -who was then Prime Minister- on 27 February 1985.

Professor Bruce Sayers was then Dean of City and Guilds and made the introduction. This version of the speech is the full version. The one already seen in the C&G centenary video is edited down to fit into a specific duration. Here then is the full, unedited version, from the original 1985 master tape.

Here is the link to the City and Guilds Celebration video on YouTube. Included in that video is the tour Mrs Thatcher took of the exhibition Technology 2000 and shows some of the people she met.

Live-Net TV Network: 2 – Opening 1987

In the first part of this look at Live-Net I showed the lead-up to the opening of the system with a visit by Princess Anne to the Science for Industry exhibition the previous year. But now, we’ll see what followed on from that. Once the demonstrations were over and the Science for Industry Exhibition closed, it was time to start using the system for real. Many tests and trials took place and slowly teaching started to make use of the system. You’ll see some of that teaching in the video at the end of this particular blog entry. Even though Princess Anne had already seen Live-Net in action it was always planned that she would officially declare it open at some point. This took place from Senate House in central London and linked out to all those sites currently connected. The photo shows the Royal Party along with Richard Beckwith looking at the monitors that showed the Live-Net sites (Imperial is in the centre). On the 28 May 1987 the system was buzzing with images going backwards and forwards to Senate House. BT were standing by as part of the demonstration and to ensure 100% connectivity! The person given the overall responsibility for the connection and use of Live-Net at Imperial College was Professor Ernie Freeman (1937-2022) then in Electrical Engineering.

Ernie handed over all of the technical tasks to me and that involved the planning of any ‘studio’, purchase of equipment and so on. Initially we simply used the TV Studio as this had cameras, sound and monitors. Later we produced a separate studio solely for Live-Net. As I had been involved from the very start, I was asked to participate in the opening ceremony and can be seen on the right hand side (all dressed up for the occasion) with a camera control box hidden behind some flowers! The background board was a left-over from the Science for Industry exhibition the previous year. There was one final royal visit to see Live-Net, but this time it was not Princess Anne.

The IEEE were meeting at Imperial College along with their President the Duke of Kent. Ernie Freeman was asked to show off Live-Net as it was an interesting and new use of fibre optics for university teaching. Once more we used the TV Studio for the event and Ernie Freeman is seen with the Duke of Kent in this off screen photo of the actual transmission. Of course there was interest not only in how it would be used for teaching and the styles being adopted for this in teaching habits, but also in the technology. This was left to me to explain (the best I could) and to show the BT equipment being used.

There was also great interest in the central switching system and computer control. This was achieved with a terminal connected directly to the BT equipment rack and then via the fibre optic cable to Senate House. That’s me talking to the Duke and explaining our equipment rack and how the images were switched around the network.

In 1990 I made a promotional video for Live-Net. We shot at most of the connections to show how staff and students used the system. We also interviewed people to see what they thought of the technology and its usefulness. In the same year, BT attempted a sales campaign for the system, quoting its ‘ease of use and flexibility’. I’ve scanned in the only remaining brochure that featured the system and if you click on the picture it will go full screen to enable it to be read. The suggested ‘control’ box was a faked prototype and never existed for real.  The room full of participants was in Senate House (shown in the picture top left of the page). Live-Net eventually fell foul of the technology which was moving forward very rapidly. The system was analogue and BT was already changing into digital for most applications. The cost to convert Live-Net was considered too high for most of the participants of the system and Imperial College was one of the first to drop out. A slow decline followed and the Internet simply took its place.

Live-Net TV Network: 1 – Pre-Opening 1986

In 1985 a proposal to install an experimental cable TV network between some of the schools of the University of London came to fruition. British Telecom had pioneered the use of fibre optics with the installation of Westminster Cable Television in London. The fibre cables linked to central street boxes that then fed into homes on coaxial cables (Switched Star Cable TV system). This enables users to select what they wanted and the resulting signal was then sent back to the street cabinet and then to the home.

Moving this technology one step further on, BT proposed a system where the fibre came direct to a cabinet located at some of the Universities in London (UCL, Imperial, Kings, QMW, RHBNC and the ULAVC at Senate House). The resulting system was called Live-Net and consisted of a bundle of fibres providing 4 in and 4 out channels at near broadcast quality.  It had been decided to locate the central switch for the whole system at the University of London’s Audio Visual Centre located at Senate House. This would also act as an additional transmission point for establishments around that area, for example Birkbeck College.

Princess Anne arrives at Science for Industry Exhibitio

The installation required the actual pulling of a cable containing these fibres through ducting in London streets to the various locations. I recall the day that the cable was brought into Imperial and then through building ‘risers’ up to the TV Studio which was then located in Electrical Engineering on Level 2. A rack then contained all of the electronics which linked to these cables. The initial major job for BT was the termination of these cables to provide a connection to the optical hub. We were aware that the central switch was already in operation and the link to the Audio Visual Centre established. Imperial was to be the first connection after this to coincide with the upcoming University of London “Science for Industry” Exhibition to be opened by Princess Anne, Chancellor of the University of London on 13th October 1986. If the Imperial link could not be established then the showing of Live-Net at that Exhibition would not take place. The short video extract below is all that remains of the first moving images sent through the fibre network a few months before the exhibition. Moments after the BT engineer terminated the fibre cable, images came through from Central London. Ray Bradley was then Chief Engineer at the Audio Visual Centre located at Senate House. In the video (seen here for the first time), he takes a phone call from me to confirm establishment of the connection by BT. We had no sound at first so we reverted to using the phone!

 

The installation was indeed completed and the first public showing of the system took place during the University of London’s Science for Industry exhibition held at Imperial College between 13th-17th October. During that week the TV Studio relayed images from the Live-Net system into the Junior Common Room where screens were setup to display the channels available. Princess Anne saw Live-Net for the first time on 13 October 1986. The video below has never been seen before and I have edited it into a sequence for this blog. I also shot footage of the exhibition and I’ll include that in another entry soon.

Participants were welcomed into the TV Studio to link and talk to remote locations within the University of London. The photo shows two things, firstly on the left the incoming image from the ULAVC at Senate House, (the Studio image is over on the right) and secondly I am sitting at a terminal connected to the central switch. I was able to switch the signals going to the exhibition and also ‘to and from’ Imperial in general – all of this using a BBC Micro Computer too!

There was another event to launch Live-Net that I’ve just remembered. This time BT gathered all of those connected with the project together and did it in style. We all met at the top of the BT Tower in London in, what was, the revolving restaurant. And I have this feeing at the back of my mind that this was the signing of the documents between the University of London and BT. If that was the case, then all of that preceded the installation of the actual equipment and cabling, but I simply can’t remember now! I don’t recall any photos being taken either, which is a shame.

In the second and final part we’ll look at the royal opening and a special visit by another member of the royal family!

e-MasterClass 2001

On the 19th June 2001 Sir Richard Sykes, then Rector of Imperial College, launched the first e-MasterClass with a broadcast to distinguished guests from government and other institutions in Britain, Australia and Thailand. The launch was preceded with the statement “Topical debate between masters at the cutting edge of scientific research and peer group scientists and industrialists around the world will be launched next month in what is believed to be the first e-MasterClass of its kind”. This first 40-minute presentation about healthcare policy was chaired by Chris Toumazou and was held in the video conferencing suite, which at the time was located next to the TV Studio on the level 2 walkway.

The technology used to link the various locations was Video Conferencing using ISDN2. The equipment allowed the ‘multipointing’ of the three sites into a split screen which meant that participants could all see and hear other with very little time delay. Images were viewed on 50 inch Plasma screens, something back then that was both new and expensive.

Press release information following the second e-MasterClass announced “Professor Ara Darzi impressed participants at the University of New South Wales, Australia, with a presentation entitled Look no hands — an exploration in cybersurgery which encapsulated his team’s dynamic new approach to micro-surgery and robotics and set out his vision for the future of surgery”.

Professor David Phillips presentation

 

 

Live Internet streaming came later

The e-MasterClass, as originally intended, carried on for just over a year when they turned in Schools e-MasterClass. These potentially had a wider audience and continued Imperial’s links with schools in general. On the 10 July 2002 David Phillips from Imperial and colleague Steven Bown from UCL gave “A little light relief”. Again a pre-event announcement said “A Little Light Relief”, will provide an interactive overview of the subject that will give Year 9, 10 and 11 students the opportunity to engage with scientific developments” In the recording of the event (below) you will notice that the chairman is Noel Edmonds. He owned the Video Meeting Company which supplied Imperial with the Video Conferencing equipment. As publicity, he was persuaded to take part.

These initial events were successful. But the schools were all connecting using ISDN2 which few other schools had available. It was obvious we needed to revert to using the Internet which all schools did have available. However, what no one had told us at the time was that almost none of the schools could Video Conference connect to IP addresses outside of their own grid (for security reasons). So, we started to stream events in parallel on the Web. Again, schools could not connect as they were limited to a strict list of URL’s. None of the schools were prepared to change this list and slowly over just a few years the whole e-MasterClass just stopped!

In 2001 we made a promotional video to show the potential of the original  e-MasterClass. The video is largely based on Richard Sykes presentation in June of that year. It includes shots showing what the remote end of the links were seeing. These days the technology allows people to link from their computers and this gives the possibility to link at night, but to do so from your home not from a University room. There is the obvious fact that very long distance ‘live’ teaching, such as the original e-MasterClass idea, is totally governed by TIME. A time difference between London and Sydney of 11 hours makes it very difficult to bring together people who (at 10pm at night in Sydney) would rather be at home, than watching academics talking in London. Time-Difference was one of the reasons for the downfall of the original e-MasterClass. But, what we did worked and maybe just proved a point that Imperial can do such things. I had fun with these events and the tension of things going wrong was always there. The e-MasterClass was, perhaps, a little too early in terms of the technology available at its start in 2001 and could be superseded by things like Skype available on your computer at work or home.

Note that the web/email links on the video will no longer work!
