Bedales Eckersley Lecture – from 1966 to present

By Dr Harry Pearson (staff, 1977-2006), former Head of Science and Houseparent

In my own personal history 1966 is a key year that I always remember and use as a reference point: it is the year, age 18, I left school in the July and started university at UCL in September. Also, all football aficionados remember 1966, as the only year England won the World Cup. I can remember the day as if it were yesterday. (One hundred years before, 1866, was one of those annus mirabilis years in science where so much was happening that would change the world, we live in. Darwin was advancing his work on natural selection while unbeknown to him, an Austrian monk, Gregor Mendel, was carefully collecting data on peas which would lay the foundation of what we now call genetics.) Eleven years on, I left the university world of chemistry and arrived at Bedales in September 1977.  It was then I discovered that 1966 is also an important year in the history of Bedales, as it was the year of the inaugural Eckersley Lecture.

Thomas and Peter Eckersley were students at Bedales shortly after the school’s foundation. Thomas, 1886-1959, was a student here between 1897 and 1904. Peter, 1892-1963, was at Bedales between 1902 and 1911. They enjoyed science tremendously and the teaching they received engendered a sense of discovery and investigation in both of them. While here they became interested in the emerging field of radio transmission and carried out some amazing experiments. The photographs below show them at ‘Wavy Lodge’ (a hut near the present-day Music School) where they carried out some of their experiments on radio transmission. Their great friend in this enterprise was Bob Best whom I was pleased to meet at the lectures of the late seventies, still as enthusiastic as ever.

Both Eckersley brothers went on to have distinguished careers: Peter became Chief Engineer when the BBC started in 1922. Thomas, who went to University College London, where he studied engineering, then went on to Trinity College, Cambridge, where he studied mathematics. He then joined the Marconi Company where he stayed most of his career where he carried out important research in the field of Radio waves becoming FRS. His work was concerned with how atmospheric effects affected the transmission of the waves. He went on to win the prestigious Faraday medal in 1951. To give an idea of the importance of this award it can be noted that the winners in 1950 and 1952 were Sir James Chadwick, discoverer of the neutron and Nobel Laureate, and Berkeley physicist Ernest. O Lawrence, inventor of the cyclotron and Nobel Laureate, respectively, two of the better-known Nobel Prize winners. The contribution by the brothers in the field of Radio transmission is extraordinarily significant, and something that Bedales can feel very proud about.

The lectures were set up by a group of Old Bedalians as a memorial and tribute to the outstanding contribution to scientific progress and thinking made by the Eckersley brothers. They are meant to have a broad appeal and stimulate interest in, and appreciation of science, rather than just record scientific research. It was always hoped that non-scientists would find them of interest. It seems appropriate that several directors of the Royal Institution have delivered the lecture as one of the aims of the ‘discourses’ at the institution seem very similar to the aims of the Eckersley Lecture.

The first lecture was given in 1966 by Professor Sir Lawrence Bragg who won a Nobel Prize for his pioneering work using X Rays in the elucidation of chemical structure. Indeed Bragg’s father also demonstrated the use of X rays in medicine. It is hard to overstate the significance of this first lecture.

In 1966 it would have been difficult to find a more senior, or more famous, scientist in this country, or indeed the world, than Lawrence Bragg, the first person to deliver the Eckersley lecture. Not only was Bragg a Nobel laureate but at the time he was the only person to have won the prize with his father, William Henry Bragg. What is more, since their discovery, the use of X rays, in structure determination, is one of those things that has changed all our lives. He won the prize as far back as 1923 as a member of the Cavendish Laboratory in Cambridge, a location that was virtually rewriting science for the twentieth century. Like his father, the younger Bragg went on to head the Cavendish, and become director of the Royal Institution.

To further emphasise Bragg’s pre-eminence, it is important to realize what point his use of X rays in structure determination had reached at that time. Several people in the Cavendish were working on the elucidation of enzyme structure, most notably Max Perutz and John Kendrew. Both went on to win the Nobel Prize for their work on the structure and function of Haemoglobin, the vital oxygen carrying protein in blood. At this time their work represented the cutting edge of science. Another duo in Bragg’s sphere were the pair Watson and Crick who were working on the structure of DNA. Their eventual publication of the structure, which marked the advent of Molecular Biology, is seen as the greatest discovery of the century. It was Bragg who proposed them for the Nobel Prize.

Watson and Crick were awarded the Nobel Prize for their work in Bragg’s laboratory in 1962. Their work would throw dramatic new light on the fields set up by Darwin and Mendel in 1866. The work in Bragg’s team was reaching towards the very heart of life itself.

When Bragg came to give the first lecture in 1966 it would be hard to think of a more eminent person in British intellectual life.

The subsequent list of speakers is very much a who’s who of British science with names like Colin Blakemore, Herman Bondi, Ken Pounds, OB Sebastian Pease, Nobel Laureate Max Perutz, Dame Jocelyn Bell-Burnell and Sir Roger Penrose among others.

I must say something here about Bas Pease. Bas gave the Eckersley lecture in 1982 entitled Nuclear Energy and the Future. Bas had a glittering scientific career becoming head of the project doing research on nuclear fusion. He may be the leading scientist that Bedales has ever produced. Bas was a powerful supporter of the Bedales Science Department and we were all pleased when he came to the opening of the new science buildings in 2001.

The 2006 lecture was given by one of my previous mentors Professor Brian Johnson FRS, formerly Head of Inorganic Chemistry at Cambridge and Master of Fitzwilliam, and also a governor of Bedales. When I wrote to him thanking him for coming, he said that for him it was an honour to join such a distinguished list of speakers. I think the founders of the lecture can be proud of what they have set up. The Eckersley brothers would also be proud of what goes on in their name and that science thrives at Bedales. 1966 was indeed an important year in the life of the school.

Bedales Greenpower team competes at prestigious Goodwood Motor Circuit

By Alex McNaughton, Head of Design

For the last eight months a team of approximately 20 students from Block 3 to 6.1 have been building and electric race car in the Design workshop. We have been doing this with the aim of competing in the national Greenpower competition. It would not have been possible to even start this undertaking without the very generous granting of funds by the Bedales Parents’ Association (BPA) nearly a year ago.

The Greenpower Educational Trust organise this annual competition each year with the aim of engaging young people about science and engineering by challenging them to design, build and race an electric race car which the students drive themselves.

It was with great excitement, and trepidation, that 12 students from Block 3, Block 5 and 6.1 accompanied by three staff entered our first ever event last Sunday (8 May) at one of the spiritual homes of motorsport in the UK – the glorious Goodwood Motor Circuit. It was a fantastic day in which we experienced the full range of emotions associated with any form of motorsport.

The day started off well with a few practice laps to fine tune the car and clock up some all-important driver experience. Unfortunately however our hopes seemed dashed moments into the first actual race of the day. The car suffered a power failure resulting in only about half our power making to the wheels. Our drivers persevered for a few laps until we decided to pit the car and remedy the issue. After nearly two and half hours of trouble shooting, maintenance and stress we managed to get the car back up and running. We were very fortunate that a couple of Greenpower volunteers and one of our competition, in the spirit of our shared endeavour, provided us with some assistance. Many many thanks to those who helped us in our hours of need. Frustratingly no one could accurately diagnose the mystery gremlin so we prepared the car as best we could and entered the second round.

Thankfully the period of doubt and anxiety was swiftly replaced by heart racing joy, elation and exuberance as the car and drivers performed fantastically well in the second round. Our car was fixed, it leapt to life as it should and sped away clocking up an above average 28 miles of racing in the afternoon. The relief was wiped from every face – we had succeeded and were competitively racing! It was an awesome feeling to be able to share in this success and reap the rewards of our many hours of hard work in building our first race car.

It was a long but utterly worthwhile day spent in the wonderful sunshine at Goodwood culminating in an incredibly successful first outing for the car and team. I am so incredibly proud of all who helped build the car, those who raced it and to all those who accompanied and supported us on the day.

I would like to say an enormous and heartfelt thank you to the BPA on behalf of the entire team for the opportunity to get this far and for the many races ahead. We are already planning ways to improve and prepare the car for our next race in September at Dunsfold.

Happy motoring to you all…

Students hear from leading Oxford researcher on cell regeneration

By Liz Stacy, Head of Chemistry

Giving students the opportunity to see science in action is not easy during these strange times, but the University of Oxford did a brilliant job this week by holding a virtual chemistry conference.

Sixth Form chemists and biologists were treated to an excellent talk by Professor Angela Russell, on the subject of ‘Cures from within: can we use chemistry to teach the body to heal itself?’ Her research is looking into creating a molecule that can stimulate the body’s own ability to regenerate cells. Her target disease is Duchenne Muscular Dystrophy, which primarily affects boys; those with the condition are unlikely to live beyond their early twenties due to the muscle degeneration that affects organs, including the heart and diaphragm.

Angela took us through the breakthroughs and setbacks she has experienced, as well as the direction in which the research is currently heading, which looks very positive. It is a hugely significant area of research as it opens up the door to being able to use the same kind of treatment for diseases like Alzheimer’s. 

Angela talked about setting up a private company, highlighting the importance of the link between academia and the private sector in being able to bring this kind of research to life.  Most importantly, when asked about which degree is best to study, she said that in her opinion Chemistry was much more useful than Biochemistry or Medicine for this particular area of research. Please make a note of that all Sixth Form chemists!

Block 3 get creative for Atomic Models Project

Atomic-Models-lrg

By Olly Hoult, Teacher of Chemistry

This week the Chemistry Department instructed Block 3 to construct models an atom and an ion as part of the Atomic Structure and the Periodic Table topic. What makes Chemistry such a challenging subject is that it involves studying a broad range of abstract concepts. Learning about atoms and ions is an example of this.

The building blocks of the universe are so small they are almost impossible to visualise. Therefore scientists use models to help conceptualise the mysterious quantum world. The model of the atom is ever evolving as scientists produce new experiments which question previously accepted theory. We believe model building is a necessary tool in science teaching as it gives students a more authentic experience of the scientific process while as teachers it gives a more detailed insight into what students have learned from this topic. In these challenging times of remote learning we also felt the task was useful as an exercise to get students off their screens and really let their creativity take over.

Joel Edgeworth has this to say about his model: “For my atomic model project I made a neutral neon atom and a positively charge Sodium ion. For my project I used pizza boxes and the stands which the pizzas are held on. I made two models for each particle, the nucleus and the electronic configuration, and I used a tea grain to show the relative size of a nucleus in proportion to the rest of the atom / ion.”

Bedales scientists support Dunannie STEM event

By Liz Stacy, Head of Chemistry

Last Saturday was Bedales Pre-prep, Dunannie’s STEM themed Open Morning. Five of our Block 5 students – Rhiannon Griffith, Milo Whittle, Ben Bradberry, Mabel Watson and Athena Lucas – filled their lab coat pockets full of chocolates (the one and only time they will be allowed to put food in a lab coat!) and headed down to Dunannie to help the children with their science experiments.

There was an amazing range of experiments on offer, from making lava lamps using immiscible liquids and building circuits to power buzzers, to programming the Beebot robots to move and light up on command and looking at field line patterns using magnets. The students were tasked with judging each exhibit on presentation and also the scientific knowledge of the children manning the experiment. They also fielded questions from prospective parents about what studying at Bedales was like and the excellent opportunities on offer for students interested in pursuing science. I thought Milo was maybe a bit harsh giving one small six-year-old five out of ten for scientific knowledge – he did award a lot of chocolate though!

Biodiversity at Bedales

Bedales-estate

By Mary Shotter, Biology technician

Over the past few weeks, in collaboration with a group of Block 3 Outdoor Work students and the Sustainability Group, we have begun the huge task of cataloguing the school’s biodiversity.

We started with the Lake, where we discovered 28 different species of freshwater animals, including water boatmen, dragonfly and damselfly nymphs, whirlgig beetles and flatworms. A walk around the centre of the site revealed 38 species of tree and 19 birds, such as the green woodpecker and nuthatch. The use of a moth trap also showed there were 14 moth species in the wildlife garden behind the Science department, which is remarkable, considering it is late in the year.

6.1 biologists hear from leading scientists

Venki-Ramakrishnan

By Mary Shotter, Biology Technician

Biologists in 6.1 travelled to the Apollo Theatre in London to hear a series of lectures by some of the country’s leading scientists as part of A Level Biology Live.

First was 2009 Nobel Prize winner and President of the Royal Society, Professor Sir Venki Ramakrishnan (pictured above), whose many scientific contributions include his work on the atomic structure of ribosomes. Ribosomes exist in their millions in every cell, and are the site where genetic information is read to synthesise proteins from amino acids. He began work on ribosomes in the late 1970s and eventually discovered their complex three-dimensional structure in 2000, with the aid of X-ray crystallography.

Next, Professor Robert Winston – who was the Bedales Eckersley Lecture speaker in 2013 – spoke about manipulating human reproduction, from his work in vitro fertilisation, through to regenerative medicine such as stem cell research and epigenetics, which may turn out to be the most important biological development in the years to come. However, he warned that manipulating the human will always be dangerous, uncertain and unpredictable.

Science update – Dr Tim Mason lecture and ‘Meet the Scientist’

smallpox-lecture

By Richard Sinclair, Head of Sciences

Last Wednesday there was a 3i/science lecture given by Dr Tim Mason on the subject of Edward Jenner and the development of vaccines.

As with all of Dr Mason’s lectures, this was a rich mix of social history and scientific information and it traced the early origins of the Variola viruses and the evidence for early smallpox outbreaks worldwide.

Benjamin Jesty and Lady Mary Wortley Montagu played important roles in the work that eventually led to Edward Jenner trying out his vaccine on James Phipps. Dr Mason took us right up to the present day, where the smallpox is eradicated worldwide, with only a few samples safely (we hope!) held in labs.

This was a really well attended event and we are once again grateful to Dr Mason for such an excellent evening.

The next evening, 6.1 Biologists visited St Swithun’s, where there was a ‘Meet the Scientist’ evening. Students heard an inspiring talk by a young physicist who described her scientific journey from Cyprus to Germany to England and the trials and tribulations of working on new projects in new countries.

Afterwards, there was the opportunity to meet and hold discussions with a range of scientists – including a surgeon, marine ecologists, neurologist and more – to find out about their own work and hear about their own journeys. It was a useful and stimulating event that introduced students to a range of new opportunities.
