Where Are You Headed?

where are you headed?

do you have an idea where you are going? do you have access to a map?
sometimes you don't.

where were you before this place? where were you before that?

somewhere new, following the map, imagining the next turn or direction. are you looking out for the next landmark on this trek?

you came from some place.
can you return?

Matching Demand

matching demand:

the match between demand and supply happens and there is a price, without this, there is no progress. often there is a distinction between what is stated and what may only be implied. as negotiations develop, this becomes clear.

say what the demand is! be forthright. be prepared.

when demand is great, and supply is little, and negotiations fumble, the realization strikes that the price is more. supply may happen and economic attention will be diverted to this rare resource.

what the demand is may be complex or it may be simple. what is the primary interest?
a beef sandwich? or a chicken sandwich?
type of bread? cheese? toasted?

matching demand may be inexact. requirements differ. timescales matter. individual sectors of the economy may proceed in an independent fashion for years, on their own plans and their own budget.

Numerical Algorithms

numerical algorithms:

these are series of numbers which could be used in programming. each number in the series is a code for a function that needs to be defined.

for example:
1,2,2,1 or 1221

what does that mean?
it could mean start at one, increase to two, stay at two, then decrease to one? it could also mean start at position one, progress to position two, stay at two, return to one!

Frustration and Sleeplessness

frustration and sleeplessness:

why can't you sleep? are there long running urges? things you have been wanting to do but haven't got around to doing them yet? do you procrastinate? are you sleeping with something going on in your mind?

why not hurry up and do them?

you may sleep better!

Geography and Navigation

geography and navigation:

roads, buildings and crossings. we look up, we see the sky and stars. we look down, we see the ground. many rely on maps to guide us. where does this road lead? who has walked here before?

where is the supermarket? where is the school? where is the library and the parks too? some maps place importance on different land marks. on some the roads are printed large, others the main attractions, some the playing fields and entertainment venues.

on the subway or underground train network:

at the cross over station....
how to get to the next line? here it gets confusing. there are signs hopefully, to guide us, otherwise we are hopelessly lost. there are straight paths but they turn right and left. you realize after several left and right turns you could be facing any direction, all sense of direction is lost. some would say keep turning right, others may say lets go back. where is the sign?

in any developed town, it is important to remember that the supermarket is where everyone has been. if X starts talking off about the school her children go to and Y says she sends her sons to another, you can conclude this is a town where there are young children and community life is centred around families. commuter towns have sprung up and distance to the railway station or bus station is the measure of any property.


Some Examples of Mathematical Series:

some examples of mathematical series:

let us examine some mathematical series, which seem to be random combinations of the first four numbers in the decimal number system:

leads to 43-12=31

leads to 43-21=22

leads to 34-21=13

leads to 34-12=22

note 21-12=9 and 32-23=9 and 43-34=9
