Everything is in motion… Arthur M. Young and Isaac Newton both knew that, but in different ages and different ways. Let’s take a slight detour into some basic ways of looking at one of our fundamentals – the way things *move.* Our search for Arthur M. Young’s ‘geometry of meaning’ will be enhanced if we can enrich our vocabulary…

Someone in the age of Newton would have said. “This chair upon which I sit is plainly still.”

We can be cleverer than that, now. We all know that our planet is rotating once per day. We may remember that the Earth orbits around its sun once per year. We can even know that the atoms from which the chair is made are themselves in constant motion, albeit within a quantum envelope which *renders them solid* only when they are observed. The chair is therefore in constant motion, but most of that motion is irrelevant to the *scale* of human life. The rotation of the Earth is not likely to upset the stability of the chair, but it would be theoretically possible to create a hyper-sensitive chair that was…

Newton did not know of atoms, though the ancient Greeks discussed their necessity. But he knew that there had to be a limit to how many times you could divide something. At that *limit* you would find the essence of matter. He was very adept at envisioning the practical consequences of pursuing things to their limit…

He knew that things moved *differently*; not just in how one thing could overtake another, but that – within how they moved – there were differences of what we now call ‘rates’. To grasp this, we need to revisit the idea of a *rate*. If I have a dripping tap, and it results in one gallon of wasted water, measured over an hour, then I have loss of one gallon of water *per* hour. That is a rate: it is one relevant number divided by another – *something per something else*. It is a measure of how something that changes (dynamic) behaves with respect to something else. But our dripping tap may not waste water in a uniform way. Within that hour there may be peaks and troughs in leakage due to aspects or factors not known about in our ‘averaged’ one hour period. This is important to hold in mind when thinking about ‘motion’, too.

In Newton’s time, it was known that the ‘motion’ of things had different aspects. Imagine Isaac Newton as a child playing a game whereby he used a fallen branch of a tree, suitably trimmed with his penknife, to strike stones in his garden to see how far they would fly. He would notice that such stones went from being stationary (*at rest*) to suddenly going as fast as they might (*a maximum*) before travelling through the air in an *arc* and falling to earth again. The motion of the stone would therefore vary from nothing (taking out the Earth’s motion) to maximum speed – as it climbed into the air; to a point where what we now call gravity caused its upward motion to cease and its downward motion to increase, even though it was still moving away in terms of distance from the child Newton in the garden. Thereafter, the grass and earth would tangle its motion and it would come to rest again.

If we measure the whole of this motion, we might simply conclude that the stone was whacked by the strong child wielding a stick and shot down the garden for a length (*distance*) of, say, 10 metres. If a modern time instrument had been available, we might also discover that it took five seconds to come to rest. This would be accurate as an ‘average’ of what had happened, but would tell us little of the stages of the lifecycle of that overall motion – the interesting bits!

The above motion of the stone (with the help of a modern timer) would yield a measure called the speed or* velocity* of the stone of as: 10/5 = 2 metres per second: distance divided by time. But that’s not what happened, except seen as a historical thing. What really happened is that when child Newton whacked the stone, it didn’t just have a constant speed; its speed changed from nothing to its maximum value, sufficient to propel it (with the correct angle of strike) into the air in its graceful, if short, arc. Thereafter it slowed and sank through the air while still travelling along the line of its trajectory – the direction in which it was whacked. After this, it landed, bounced and came to rest in a scruffy (but real) way in the tangle of grass and mud.

Aside from my borrowing of his childhood, the real Newton had the genius to realise that the first part of the motion, (from rest to its maximum) was not just speed, but an increase of speed (from nothing to its maximum) that *had a different rate*. This was caused by the whacking of the stout stick, which transferred its energy to the stone, slowing the stick and thrusting the stone into space. This change of speed or velocity was named acceleration, and it was seen by Newton as something different to velocity, itself. This was a breakthrough in thought and measurement, and marked Newton as a true genius. It would take hundreds of years for Newton’s discoveries to filter into the mindset of the age. Many people today have little idea what he achieved, and yet our age of powered motion is built on his discoveries and the accompanying mathematics of calculus. The “Newtonian” world is the world of classical physics, and this view of how the world operated persisted until the advent of Quantum Theory in the early years of the last century.

Returning to Arthur Young’s discoveries. Young examined the symmetry of what Newton had discovered in the following way.:

Motion begins with distance from a start-point. In our example above the stone travelled ten metres. This is simply a length, which we can call ‘L’. A length ‘L’ applied to a start point (or Origin), without consideration of its motion, simply gives us a new *position*.

If we want to go further and investigate the real motion of our stone, we consider the time it took to travel the distance. We can call this ‘T’. The length (L) per time (T), written L/T (length divided by time) gives us a rate called speed or velocity – example miles per hour. This ratio of L/T is a basis for all motion and reduces things to their simplest expression.

So, what about acceleration? Remember that this is an increase of velocity not distance. If my car accelerates, it is now travelling at, say, sixty miles per hour rather than fifty. The acceleration has been ten miles per hour, *per hour*. In other words the rate of change of the velocity.

Summarising this:

Position = L

Velocity (speed) = is the *rate* *of change* of position or distance = L/T

Acceleration is the *rate of change of velocity*, which is L divided by T times T. This new expression, T times T is written T squared, T with a little ‘2’ to the right of it like this: T²

Arthur Young was pursuing the fit of the science of motion to the Fourfold model of meaning we discussed in the first three of these blogs. He needed a fourth term to follow the sequence:

Length (L),

Rate of change of Length, (L/T or velocity)

Rate of change of rate of change of Length, (L/T² or acceleration)

The missing term (L/T³) would be the next in the series and would complete the integration of the human world of motion with Young’s fourfold map of universal meaning…

But there was no recognition of a fourth term (L/T³) of Length and Time in physics… Yet Arthur M. Young, creator of the modern helicopter, knew there was a commonly understood concept that matched this – he had used it to make his helicopters safe…

*To be continued…*

I really do understand, and thank you for trying! The next post will cover some of the same ground without the maths… how’s your geometry? Just kidding 😎
