The dotted box represents any character (presumably a letter or bigram of letters). All the other notation consists only of the digit 2, in various fashions with occasional additional punctuation, and labelled as to what the 'purpose' might normally be of any particular element(s) as indicated, with respect to the general term, in the following fashions:

:A preceding superscript. "<sup>2</sup>H" would indicate the isotope of Hydrogen with the atomic weight of two, i.e. deuterium, which is most often encountered when working with the atomic level of matter where the total number of neutrons and protons in the atom is important.

:A preceding subscript, "<sub>2</sub>He" indicates the atomic number of an atom, which is the number of protons it contains, and thus a guide to the number of electrons it usually has and hence its potential chemical intersctions.

:Extending the trailing subscript with a comma-separated value usually indicates a multidimensional array (e.g. establishing a 2-by-2 square of numbers, or this particular position in such an array), which is in the realms of matrix mathematics.

Revision as of 06:14, 3 May 2022

Friends, Romans, countrymen, lend me your ears;

I come to bury Caesar, not to praise him.

The evil that men do lives after them;

The good is oft interred with their bones;

So let it be with Caesar. The noble Brutus

Hath told you Caesar was ambitious:

If it were so, it was a grievous fault,

And grievously hath Caesar answer’d it.

Here, under leave of Brutus and the rest–

For Brutus is an honourable man;

So are they all, all honourable men–

Come I to speak in Caesar’s funeral.

He was my friend, faithful and just to me:

But Brutus says he was ambitious;

And Brutus is an honourable man.

He hath brought many captives home to Rome

Whose ransoms did the general coffers fill: Did this in Caesar seem ambitious?

When that the poor have cried, Caesar hath wept:

Ambition should be made of sterner stuff:

Yet Brutus says he was ambitious;

And Brutus is an honourable man.

You all did see that on the Lupercal

I thrice presented him a kingly crown,

Which he did thrice refuse: was this ambition?

Yet Brutus says he was ambitious;

And, sure, he is an honourable man.

I speak not to disprove what Brutus spoke,

But here I am to speak what I do know.

You all did love him once, not without cause:

What cause withholds you then, to mourn for him?

O judgment! thou art fled to brutish beasts,

And men have lost their reason. Bear with me;

My heart is in the coffin there with Caesar,

And I must pause till it come back to me.
