16 Perception;

I am now beginning to talk about motivation, but first need to talk about perception.


17 Memory and memory of what was perceived;  

At aged about one my memory of an inoculation is as if I were looking down on myself screaming arms and legs going, I remember the doctor telling to mum to hold me and preparing the needle, the pain in my arm was dreadful*. I don’t recall what I was thinking but my guess is that, I did not believe what I was being told, that it would not hurt when the previous inoculations had hurt.

* The pain in my arm returned periodically into my adulthood but the frequency diminished when I associated it with the memory.
Two other memories from age two or three (1961) I guess I remember a pick-nick with mum in a field full of wild flowers. The following year there were no flowers in the field, probably because pesticides where being used as farming intensified.
 
 

Again age three possibly this picture of me at the top of the sandunes in Ilfracombe, Devon, I remember my legs going frantically, and thinking how hard it was to get up the dunes, I had not mastered climbing on sand then. My point is that on these occasions I remember what I was thinking. I also remembered the place names on the way, but sometime after age three I lost confidence in remembering names and place names.

Mum pointed out smoke through the train window on a journey to Brighton so therefore we were travelling on a steam train that was in the 1960′s. I did not see the smoke, but I believed my mum, so I could differentiate what I was told and what I observed. 

 

18 Perception of a picture;


Lake Buttermere, Cumbria.

The paths and rivers draw your eye into the picture. Thereby changing the perception, that is boosting the appreciation of the picture.


19 Music changes mood;

I used to discuss these things with dad. He called the music of Delius, Vaughan Williams, David Bedford picture music because of the there particularly clear pictures and atmosphere that comes with listening to that music. He was berried in a woodland looking at the light twinkling through the trees, best captured in First Cuckoo of Spring by Delius. Fats Waller played wonderful Jazz on a church organ, as a son of a baptist minister his music could crossover, and thereby bring people together. https://sites.google.com/site/engineerperspective/my-family/john-harold-lohmann-1929-2002


20 Media is owned by interest which distorts perception;

When something is broadcast this distorts the collective conscious by changing emphasis and creating disunity, and sells news, but although we can chose not to buy the distortion by its magnitude, has entered the collective conscious. The widely reported Northern Ireland Bank Raid (2004) was reported as a professionally organised raid. The BBC quietly balanced the report in the middle of the day with a long article explaining that the robbers took new identifiable bank notes leaving the old bank notes, and filling the van many times going back and forth to take the money away.


21 Random Numbers can’t be generated by humans;

Durring a diploma in Engineering management lesson the tutor drew a box with 10 x 10 squares, with hidden 25 squares, and within those 25% he hid 10 very secret squares. The class suggested squares but did not start finding the secret squares until most of the others had been tried, and we found very few of the 10% of the very secret squares until there was hardly any other squares to chose from. The tutor said that Electronics Engineers also have common favorite two off 1 colour and 1 number pairs. The patterns change for people of different disciplines. (R Buchanan, 1980-4, Bromley College of Technology)


22 Science and Engineering;

Traditional engineering (Watt) and science (Newtonian) is based on precisely measuring things doing maths to reaching precise answers. In the 19th century Joseph Whitworth improved the accuracy of making flat surface plates. The basic method of grinding three surfaces together was substituted by using Engineer’s blue and scraping as well. In Physics there was a debate about whether light was a stream of particles called photons, or waves like radio waves, the maths is different but works both ways. If coherent light is shone through a diffraction grating to photographic film an interference patten is created which can be explained by wave theory and particle theory.

Dr Who’s Tardis is a machine that generates waves that form it’s material substance, cannot be destroyed, and the Tardis merges in to its surroundings. For convenience of 1960′s TV production, the Tardis is stuck as a police box, as noted in the first episode by the Dr when we first saw him step out of the machine.Although many things from mathematical theory become science fiction and then are developed, I don’t envisage such a machine being developed. There is no technical or resource solution for everything, acceptance of finality is important.

When using a digital (CCD) camera with good light level the number of electrons formed by photons is high enough for the light to be a fairly exact measurable quantity, Newtonian science applies. When using the camera in low light you may increase the ISO and consequently you could be detecting 100 photons or less within each pixel (Fairchild Camera Corporation – Fairchild Semiconductors CCD data book 1970′s). The amount of light detected is small and a few electrons either way, due to there random nature become noticeable, and you will see noise in the picture, partly because of the variations in the number of photons received and also electrons formed by heat become significant. The observed light has become based on a statistical probability, we have moved away from traditional Newtonian science and engineering in to quantum theory. Nano-technology is base on the random nature of small numbers of particles consequently the behaviour of an element is different.

So is light photons or waves? An experiment based on Newtonian science and engineering was carried out where a light of one photon per hour was projected through the diffraction grating on to photographic plate. The outcome was that there was still interference so the light must be waves, but must it? This was Michaelson-Morley experiment, But “A Heretics guide to physics” (Wireless World series 1982-1983), explains that there is no such a thing as a light source that emits one photo an hour in the same way that there is no cliff edge that crumbles at a rate of one pieces of rock an hour instead nothing happens then periodically the cliff face crumbles. 

Quantum maths is a way of calculating the outcome of more than one random event, once the observation is made instantly we know which way the event went. There is a thought experiment that involves a photon passing through or being reflected by a half silvered mirror, one path results in a cat in a box being shoot (Schroedinger’s Cat). It is not until you open the box and find out the state of the cat do you know which way the particle went, and you know instantly, that is faster than the speed of light, that the particle did not get to it’s alternative destination. The maths works on both possibilities being true or false. It is my opinion that nothing has physically travel faster than the speed of light, unlike what is said of quantum entanglement, Or that observation changes the situation in a mystical way. Things can be expressed in language, that are grammatically sound, but physically invalid.

In the same way that Bible teachings were once taught in Latin and stories as miracles to mystify and empower the church. Quantum physics is not magic, in the same way that in maths used in electronics for alternating current with reactive loads uses J the imaginary square route of -1 and real numbers, is not taught as mysterious, but as a technique. Understanding alternating current and its relationship to voltage is quite a challenging aspect for students to learn.


23 Non-Lauguage based thinking;

I observe as an Electronics Engineer that I can think in a non-language way, the thought from feelings turn into language as necessary in order to do any maths to further the objective. But when a non-verbally reasoned objective is translated consciously to language that language may be imprecise, but the feeling and engineering is spot on. I started making the oscilloscope when I was 15 and developed between 1973-1977 my language skills have improved considerably since then. I have during my subsequent career developed scientific instrument that have a nice user feel and technically quite elegant and in performance very good without being able to express what I was doing in language. I have subsequently written up how those instruments work the maths and engineering are conservative and sound when expressed in language as they felt in emotions when I developed them. 

The point I am making is that language is not how we analyse it is how we express things to each other, with time that translation becomes seamless as if we think in language.
