Jock, we must then blame those who can not calculate volume of a pyramid, find the elapsed time for the first car meeting the second in the problem of two cars moving towards each other (with data enough), or to use formula of the Euclid theorem.
These are also very basic knowledge any school boy must learn almost at the same time litmus paper taught. It was to remind for who could have forgotton Litmus Paper as well as the solution of the problems above.
I'm not sure what you imply by "basic material"
I used the term basic for substances having alkali property (base), you had to guess I think, for to not use alkali.(Perhaps alkali is more understandable) You can be sure basic is that thing what you understand.
Your assumption that blue/ alkali (I'm not sure what you imply by "basic material") is good, and red/ acid is bad is purely subjective: in scientific terms, it is meaningless
Vinegar is really very nice on chips. But amazingly sometimes it can be one of the causes of ulcer. And more amazing than that, your understanding blue-red comparison, as acid good, alkali bad. Perhaps if you can read again the topic you will realize that is not a comparison of alkali and acid.
One year after from chemistry lessons including acids and alkali we took a meaningless, purely subjective lesson; Psychology. Not only an ordinary school boy, even some of students not related to lessons after decades could remember blue and red's meaning from those years. What to say, perhaps you also did not interest in lessons after taking the basic knowledge of them.
I will not repeat what I said in my topic, let us look what also meaningless website wikipedia.org says about blue-red.
Positives - Passion, strength, energy, fire, love, sex, excitement, speed, heat, leadership, masculinity, power
Negatives - Danger, fire, blood, war, anger, revolution, radicalism, aggression, stop
Positives - Seas, skies, stability, peace, unity, harmony, tranquility, calmness, coolness, confidence, water, ice, loyalty, conservatism, dependability, cleanliness, technology, winter
Negatives-Depression, coldness, obscenity, conservatism, technology, ice, winter
What wikipedia says about red negatively, let us repeat; blood, danger, war, aggression...
And what did I say in my topic; blood, as mentioned wikipedia, weapon instead war (sorry Jock, I may be caused you confuse with writing weapon instead of war), you can adapt the others...
Even its a less negativeness relatively, blue; I write again from wikipedia; peace, confidence, unit, tecnology (I think you can understand here tecnology. is used in good form, and sorry again if you could not understand the term tecnology from my expression in topic one more step to upwards and freedom when writing about blue.)
I had wrote about red and blue in topic from what I remind from 20 years ago. For more information in wikipedia.org website you can write colour to search section. You will see pages of documents. A little more easy way if needed;
I can write also some other sites if wikipedia is complicated.
If you surf a little on net before reply, we can discuss more effectively
In turnesol term I had to really appreciate you.
