Yesterday, I spoke in the remaining stages debate on the Product Regulation and Metrology Bill, about my specialist subject of Metrology. I talked in depth about measurement science, which, as the first elected metrologist, is the most incredible honour for me to discuss. As always with my speeches, I’ve attached the recording of the speech above and the transcript below.
Madam Deputy Speaker (Ms Nusrat Ghani)
It gives me huge pleasure to call our resident metrology expert, Adam Thompson.
Adam Thompson
Once again, it is a great honour to speak about the Product Regulation and Metrology Bill. Today, we are focused on the amendments proposed following the Public Bill Committee, on which, in common with the right hon. Member for Basildon and Billericay (Mr Holden), I was honoured to serve; I was the resident metrologist.
In Committee, we heard extensively from Members of the Opposition. They described in great depth their concerns about the Bill’s implications for international alignment of regulations; we have just heard some of those concerns from the hon. and learned Member for North Antrim (Jim Allister). Today, those concerns have once again been presented to the House through various amendments to the Bill. I will explain, with reference to state-of-the-art metrology, why those issues should not be a significant cause for concern for right hon. and hon. Members.
Mr Holden
The hon. Member and I served on the Bill Committee together. I think he misses a slightly important point that this is not about international alignment, as is put forward in the amendments tabled by the Opposition, but alignment with the EU, and that is why there is such concern from the Opposition parties.
Adam Thompson
I thank the right hon. Member for his intervention. As I discussed extensively during the Bill Committee, there is a misunderstanding here of exactly what the Bill is doing, so I fundamentally disagree with the point he makes, but I will go into more detail on it in my speech.
One of the first things one learns about as a budding metrologist is the concept of perfection. In his book “Exactly”, Simon Winchester writes of what he refers to as “the perfectionists”, detailing the evolution of the science of metrology through time and how precision engineering has been used to create the modern world that we inhabit. It is a great read, covering the history of my science in the popular mindset. However, I do not necessarily agree with Winchester in his core thesis; he talks about metrology as the science of perfection, whereas it is more accurate to think of it as the science of the good enough. I will elaborate on that shortly.
In the early days of a metrologist’s training, we learn that with more money and more time, a precision engineer can almost always achieve a more precise and accurate result, whether a straighter line, a smoother surface or a better piece of legislation, but that striving for true perfection—the absence of any fault—is always folly. Our resources are never infinite, and in the real world it is always more appropriate to strive for the good enough as opposed to the perfect. Good enough is the core of modern engineering and the fulcrum on which our world balances.
I am, as many colleagues will know, by trade a metrologist, but within the broader field, I am a surface metrologist. Surface metrology revolves around the measurement and characterisation of surfaces—surface texture and surface topography. I am the one who decides whether the leather steering wheel feels right. I am the one who ensures that car engines distribute and hold oil in all the right places to keep them running smoothly. I am the one who ensures that tyres keep us firmly planted on the road as we round corners.
Becoming a surface metrologist involves gaining an intimate acquaintance with the very concept of perfection. Always in engineering I hear people asking for a product to be made perfectly—for the angle of the corner of the table to be exactly 90° or for the surface of the microscope to be infinitely smooth. Let me put it on record that there is no such thing as perfection in reality.
Chris Vince
Despite what everyone was thinking, I am not going to suggest that I am perfection, but as a mathematician, may I ask my hon. Friend to accept that the reason perfection is not achievable in that instance is to do with the infinite—the infinite amount of numbers between 1 and 1.1, for instance, or the infinite amount of numbers between 1.1 and 1.11?
Madam Deputy Speaker
Order. I accept that we have some experts in the Chamber, but I remind Members that speeches and interventions must relate to the business at hand and the amendments.
Adam Thompson
Thank you, Madam Deputy Speaker. I thank my hon. Friend for his intervention—it was perfect. He is absolutely right, and I will leave the perfection to the mathematicians. To illustrate my point, I hear people in engineering asking for products to be made perfectly—for the angle of the corner of the table to be exactly 90° or the surface of the microscope to be infinitely smooth. To study metrology is to understand the concepts of imperfection and uncertainty and apply those to everything. If one zooms in close enough, the angle is never exactly right, and the surface is never perfectly smooth.
On Second Reading, I made reference to the optical mirrors used in the James Webb space telescope. They are incredibly smooth, yes, but to examine them at the atomic scale, one would find deviations from the nominal plane that mirror those in the Grand Canyon. Being an engineer involves accepting these deviations within the context of the work we undertake towards our goal of constant improvement—be that in the creation of, say, aerospace engines or, indeed, national legislation.
My expertise within surface metrology was in the development of X-ray computed tomography for measuring surfaces. Alongside my good friend Dr Andy Townsend at the University of Huddersfield, who made similar discoveries at the same point in history—a phenomenon that is common across science—I was among the first to be able to use X-rays to measure the interior surface of parts that were otherwise hidden to both the eye and the machine. X-ray computed tomography had never previously been good enough to measure surfaces, with the imaging resolutions achievable lagging significantly behind those required to separate measurements from noise. Previously, such measurements were not really needed, as to manufacture a surface, one generally had to access that surface with a machine tool, so one could similarly access it with a measurement tool.
However, with the birth of industrial additive manufacturing—often called 3D printing—we could suddenly make things with hidden internal geometries that did not need tool access and could not be measured. Without measurement, though, we cannot verify that the parts we make will function as we require them to.
As such, new technology was required to allow us to create additively manufactured parts, be they novel, much lighter aeroplane parts or new joint replacements finely customised to suit the individual. Alongside our colleagues, Andy and I solved this problem by demonstrating that X-ray computed tomography had become good enough to measure those surfaces.
This Bill mirrors that “good enough” paradigm. Current legislation places us at risk of falling out of alignment with the rest of the world, which in turn risks our ability as the British to maintain our position at the forefront of international science. In its current, unamended form, the Bill grants the Secretary of State the necessary authority to keep pace with the guidance of relevant experts. The amendments proposed by the Opposition would only hinder our ability to stay aligned with the continuous advancement of progress.
Jim Allister
In lauding the Henry VIII powers in this Bill, as an elected Member of this House, is the hon. Gentleman at ease with the fact that the Bill could see criminal offences created without any scrutiny or input from this House? Is he at ease with the fact that the liberty of our constituents—which I think we would be interested in protecting—could be jeopardised by criminal offences created by the Executive alone?
Adam Thompson
I thank the hon. and learned Member for his intervention, but I disagree with his assessment. This Bill is about providing the Secretary of State with the powers necessary to ensure that we remain at the forefront of science. Opposition Members have incorrectly claimed that the Bill hands over authority to foreign powers, or overly centralises it in the hands of the Secretary of State. This is not a matter of ceding control to external entities; rather, it is about maintaining the United Kingdom’s position at the forefront of scientific and regulatory innovation. It is about ensuring that the British scientists who follow in the footsteps of Newton, Franklin and Hawking can continue to lead the world in their fields.
These Opposition amendments appear to stem from a fundamental misunderstanding—or perhaps a complete lack of understanding—of what metrology and standards frameworks entail and why they are vital. I urge all Members to vote against them and support this Bill through its Third Reading.
