| 157 | \begin_layout Abstract |
| 158 | This topic is meant to be about (mathematical) physics. |
| 159 | There will be many formulas and equations, |
| 160 | and appeals to advanced topics and terminology. |
| 161 | The intent is that every statement, |
| 162 | claim and formula made here is textbook–standard, |
| 163 | and so the work here is entirely in the framework of orthodox physics. |
| 164 | That is, |
| 165 | all attempts are made to avoid crankiness and craziness, |
| 166 | and the content here should be entirely acceptable to those with a standard formal education in mathematical physics at the PhD or post–doc level. |
| 167 | And yet, |
| 168 | conventional, |
| 169 | old ideas will be presented and developed in strange, |
| 170 | unusual, |
| 171 | bizarre and outright hallucinatory ways. |

| 186 | Part Ten has turned into a bit of unmanageable mess, |
| 187 | where even I cannot find some interesting ideas I jotted down. |
| 188 | So this diary slices off this particular topic, |
| 189 | large in it's own right, |
| 190 | so that it is more manageable. |
| 191 | A recap for the new reader is in order: |
