IET Meetup: Debugging the Brain


In 2011, Ed Boyden won the IET Harvey Prize in recognition of his contribution in the field of optogenetics. Now some years later, he came to the IET to update the organisation on the progress his team have made in that field and how their contrarian approach has led to developments elsewhere.

The field combines light-based optical technologies and genetics to control the activity of neurons, enabling treatment of conditions resulting from a wide variety of brain disorders, such as epilepsy, post-traumatic stress disorder, and Parkinson’s disease.

Boyden described novel techniques, such as repeated miniaturisation of structures by injecting a lattice and using dehydration of hydrogels. This was discovered by reversing a process performed to increase the scale of neutrons in brain tissue so they could be visualised for research projects.

Marquee events like this are always very popular at the IET and this one was was very well attended. What was particularly notable was the number of well-informed questions after his presentation from researchers in similar fields who had travelled to attend the event.

Book Review: The Gods Themselves, Isaac Asimov

What a brilliant book this is, split into three parts, each telling the story from a different viewpoint.

First, we hear about the invention of the Electron Pump – a source of limitless energy that transforms life for those on Earth. However, the discovery was not by chance – the invention was only possible with the collaboration of aliens in a parallel universe, with consequences for both universes due to conservation of energy, matter and momentum. The discovery would not even have been made without the personal animosity between two scientists, Hallam (who becomes known as the Father of the Electron Pump) and Denison (the more talented of the two, whose career never recovers). Years later, some scientists discover that the impact on our own universe could be significantly worse and more immediate than originally thought, but it’s heresy to question the wisdom of the pump and their opposition is dismissed.

Second, the story is told from the viewpoint of the aliens. The imagination and storytelling are superb. Asimov describes a totally different familial and societal structure to our own, focussing on the lives of a “Soft” triad and their side of the Electron Pump invention. The triad are Odeen (the Rational), Dua (the Emotional) and Tritt (the Parental). Each has a well-defined role in society – Odeen learns, Tritt bears the children and Dua should socialise with the other Emotionals, absorbing energy from the Sun. Dua is unusual, fighting against the norms of society and yearning to learn instead of sunning herself. Odeen is the top intellect of his generation – and Tritt, too, has far more invention about him than most Parentals. Together, they have huge potential and carry the hopes of the “Hard ones” who tutor the younger generation.

Third, we experience the story from a base on the moon, where Denison migrates in hope of reviving his career. He makes friends with a tourist guide, Selene, who was born on the moon and introduces him to the culture there. As Denison’s research matures, Selene becomes his assistant – they investigate the possibility of a new technique that could counteract the effects of the Electron Pump. Yet, again, Denison finds himself caught in a battle of wits with another scientist, Selene’s boyfriend, who has other plans for the research.

Book Review: Past Tense, Lee Child

The annual publication of Lee Child’s brand new Jack Reacher thriller is always eagerly awaited. I received a lovely hardback edition of this one (it was purchased in an edition sold by Tesco in the UK, containing an exclusive short story: “The Fourth Man”).

Having read all the Jack Reacher books, I have to say this one isn’t one of the classics – for me, it took too long for the real story to begin. We follow a young, Canadian couple to a country motel following the breakdown of their car and Jack Reacher to the city of Laconia, the town where his father grew up. The motel, though, is not what it seems – the owners trap the Canadians in their room and set up a sinister gathering of like-minded individuals. Meanwhile, Reacher tracks down the location of his father’s family’s home and seeks accommodation – at the same motel. The final showdown is excellent and Reacher has lost none of his deadly skills.

Book Review: The Tipping Point, Malcolm Gladwell

This is a fascinating read, ranging across a variety of topics. What makes a great salesman? Why do are some TV programs so addictive? How do some people remain occasional smokers without ever developing a daily habit? There’s also a chapter on the magic number 150 – how the military, communities and companies have found that once a unit exceeds 150 people you need to split into sub-groups in order to maintain the same levels of cohesion.Four stars

Book Review: Name to a Face, Robert Goddard

This wasn’t a particularly memorable book – the main character is Tim Harding, a landscape gardener who finds himself chasing around the country investigating the theft of a historic ring and the death of a journalist, whilst also having an affair with the wife of a rich client. The shame of it is that there’s a gem of a plot hidden in this book, concerning the legend of the Grey Man of Ennor who supposedly had healing powers and cured people of the Black Death. His remains may still have the power to heal and are fiercely protected by local families on the Isles of Scilly.

Book Review: Deathlist, Chris Ryan

As with the other Chris Ryan books that I’ve read, this one concerns the SAS. This time, though, it’s the SAS who are subject to a surprise attack – a training platoon mercilessly bombed by a well organised team, bent on revenge. The plot follows two experienced survivors from that day as they track down the perpetrators and aim to exact their own revenge. They are helped unofficially by the UK government, including the mysterious Cecilia Lakes – a senior official destined for greatness in the UK Intelligence Services.

Like other reviewers, I found a lot of the SAS jargon and bad language somewhat overdone. However, the story itself is gripping and worth a read.

Tech Book: The Phoenix Project

This is a technical book, packaged as a very readable tale of an IT Manager who is promoted to Vice President of IT Operations across his company. Whilst Bill runs a tight ship in his small department, the company as a whole has a poor culture for delivering software. Bill is ordered by the CEO to do whatever it takes to bring the Phoenix Project (an IT re-vamp vital to the company’s business) to completion.

Much of the technical content concerns the DevOps arena and touches on issue tracking and prioritisation as well as improving time to delivery. It’s a good read as well as making some well-argued technical points.

IET Meetup: Appleton Lecture – AI and Human Digitization


The first address in this year’s Appleton lecture was given by Dr Sarah Atkinson. She gave a historical view of “fake news” created by manipulation of media, starting with the Cottingley fairies. This set the scene for Dr Hao Li’s excellent presentation of his research into animation of people, initially through long-running processes for film effects, but latterly in real-time for Animoji on the iPhone X.
Dr Hao Li - Animoji Mastermind
There are plenty of applications for the techniques, such as video conferencing, social media and even films. However, the common theme was that, as these technologies become mainstream, we should no longer assume that video evidence of a speaker saying something is actual real.

Rambling: Loweswater, Lake District

Lake District
This is a short, low-level walk around Loweswater, which is both a lake and the name of a small village. It’s also the first walk in the Pathfinder Guide. On the day that my family and I hiked around the lake, The Loweswater Show was coincidentally being held in fields nearby – making it quite a challenge to squeeze the car around the horse boxes leaving the show along the narrow country lanes. There is parking is lay-bys along the Northern side of the lake.

The route for the walk was quite easy to follow, being largely around the lake. There are some lovely sections on the North side of the lake where the path is directly adjacent to the water. On the South side, much of the route is through woodland, although there is a stony beach with several ropes suspended from the trees – we caught a sheepish teenager enjoying a swing on those before he felt self-conscious.

The walked was booked at 4 miles.

Book Review: The Kill List, Frederick Forsyth

This book follows a similar formula to The Afghan, by the same author. There’s a terrorist threat to the western world- extremists brainwashed by a radical cleric are murdering prominent public figures. A former US marine (codenamed The Tracker) must track down the preacher (codenamed The Preacher) who only posts online – and eliminate him. The Tracker recruits a young, supremely talented hacker to help locate the source of the inflammatory material – he is codenamed Ariel (disappointingly, not The Hacker!)

The constraints put in place by politicians make The Tracker’s job harder – even having located The Preacher, he cannot order a drone strike because it is a built up area. So begins an elaborate plot to bring The Preacher out of his ‘fortress’ into a remote area, where he can be attacked. First, he is discredited in the eyes of his followers, by hacking his website and posting a fake message recanting his previous statements. Second, he is informed by a trusted friend (actually Ariel, aka The Hacker) that a local warlord has kidnapped a westerner and is prepared to sell – executing the man would re-instate his fearsome reputation. Having set the bait, the tracker must recruit a lethal army unit to seek and destroy The Preacher at his meeting with the warlord.
