Definition of Turnbull Time
Turnbull Time is the length of time, in years, days, minutes and seconds it takes a fixed bottle or collection of bottles to increase by one Bridgeman
One bottle will have a Turnbull Time of one year. Two bottles will have a Turnbull Time of 182.615 days or 182 days 14 hours 45 minutes and 36 seconds, shown: 0:182:14:45:36.000000
Turnbull Time has dimensional analysis of T

So Turnbull time can be measured using a Caesium clock.
But I still don't understand how Turnbull Time can be used to estimate the half life or decay rate of a given collection of bottles. Ie. the amount of time in Kilbys that it takes for a collection of Turnbull bottles to double the Turnbull Time quotient.
Or does Turnbull time also apply to the given collection of bottles once they have been consumed and are continuing to accumulate Bridgemans whilst in the digestive tract of the cellar owner?

I am deeply honoured by this. Unfortunately, this years Nobel Prizes have just been handed out otherwise I would have started preparing my acceptance speech

PS: I think we need to build some variables into the Turnbull Time / Bridgeman theory. As I see it, each of these measures can only capture a single point in time rather than provide an expression of the real time ageing pattern of one's cellar. I think we need to define some user specific variables to take account of new purchases, consumption and leakage if we are to come up with a statistic that the world can start to put to good use.

Uncle time is the accelerant factor that applies to a newly acquired, but imperfect bottle, determining whether it will be drunk soon or laid down for consumption later..
Right now, I'm too pissed to work what that is...

This deserves a reply but, sadly (or not), I'm in the same position as Tom and am incapable of composing an appropriate reply that uses apostrophe's in all the right places.

Does the Bridgeman Quotient apply equally to Uncle Time and Turnbull Time or does the accelerant factor built into Uncle Time mean that the Bridgeman Quotient is no longer useful in measuring the aggreagated bottle age gained by a cellar over a given period of time?
Perhaps Uncle Time is actually the obverse of Turnbull Time. Turnbull Time measures the increasing maturity of a port while inside its bottle but Uncle Time measures how rapidly the bottle is approaching the time that the cork is removed and the contents consumed - ie. how much remaining maturity the contents will be allowed to acquire.
I must consider this further.

Let me be perfectly clear for all reading this chain who may be confused. The Bridgeman Quotient is the name of the measure of the sum of the ages of the bottles in a particular cellar or other defined group of bottles. Whenever referring to this measure, you must always capitalise the Q in Quotient otherwise Alex K may misunderstand and assume that you believe that the Bridgeman Quotient is a quotient and not a measure.
Does this now make it all clear?

It is not a QUOTIENT
Dictionary definition of "Quotient": a result obtained by dividing one quantity by another.
A Bridgeman is a unit of measure. Turnbull Time is a measure of time. Neither are bleeding quotients. Stop this now or I will come down there and reduce your cellar to zero Bridgemans.
Actually Turnbull Time could be considered a quotient as you divide a year by the number of bottles, but nobody has defined it as a bloody quotient, it is defined as a measure of time.

So, we have now defined Bridgemans, Turnbull Time, Kilbeys and Uncle Time as factors in our equation with the Killer Quotient adding some spice.
However, as Luc has pointed out, this may now cause some instability in our experiment so I would suggest we introduce the Conky Constant - see here for an example of what the Conky Constant looks like

This is one variable that can factor in the equation .
The Conky Constant , however has not received universal acceptance in the scientific community .
What makes the C.C interesting from a scientific point of view is Its use of oxygenation .
The C.C. has the ability ( or gives one the impression ) that time stands still .
Due to Its molecular structure ( increase in heat results in an increase in the movement of said molecules ) or Hot Air , the accelerant in Uncle Time cannot change the C.C. .
This begs the question : would a cooling down of the C.C. have a the reverse effect on a macro scale ??
