For bachelor's and master's degrees, the name can alternatively be complemented by -thesis instead (e.g., Bachelorthesis).

I consider that high praise coming from an MSc in Physics as I am only working on my BSc degree in that field. This also puzzles me, though. If you are who you say you are, then you should know all this. Moreover, you should know that I have not at all demonstrated the Lorentz transformation, but – as I just said – showed a way to derive the _Minkowski metric_ (which the Lorentz transformation just satisfies as the metric was developed afterwards by Minkowski). > ....

Unicode formally exists since 1991, has been having support by operating systems for quite some time now, and has official support in NetNews messages since 2009 through the requirement of MIME support in RFC 5536 (current status: Proposed Standard). 7-bit data lines are few and far in- between now, and even with those MIME allows to encode non-ASCII characters. However, even character encodings and sets that predate Unicode, like ISO/IEC 8859-1 and Windows-1252 (“ISO-8859-1”) already contain the characters “²” and “³”. In this case in particular the X Keyboard Extension, built-in to the X Window System, allowed me to type “^” followed by “2” to type easily the Unicode character “²” on GNU+Linux. There are other ways for other, even more widely distributed consumer operating systems. <https://en.wikipedia.org/wiki/Unicode> <https://en.wikipedia.org/wiki/ISO/IEC_8859-1> <https://en.wikipedia.org/wiki/ISO/Windows-1252 <https://en.wikipedia.org/wiki/ISO/X_Keyboard_Extension> With that said, nowadays there are newsreaders like Mozilla Thunderbird which convert some ASCII character sequences, like “^2”, to their Unicode equivalent or at least a typographically adequate form, for the display of messages. I have even written a user script to convert some character sequences to Unicode characters in Google Groups (which you are using, but I recommend against using because it is technically flawed) automagically. Finally, as Google Groups is a *Web* interface, it should not surprise you at all to see Unicode characters being displayed *there* as HTML has had official Unicode support since 1999.

[George Hammond] Well, it doesn't work on a Windows 10 (HP) computer – guess it only works on Linux or something – damn ! George

[George Hammond] ....Hmmm – wonder what would happen if I cut and pasted your "exponent" equation? ' c² dt² − dx² − dy² − dz² = 0 . Let's see if that comes through? George

Apparently I have not been clear enough. You have to distinguish between the typing and submission of actual characters (even if they are only injected into NetNews in an encoded form), which is decided and can usually be viewed *before* submission at the client computer (that happened in my case), and the interpretation of character *sequences* in a *submitted* message that is *displayed* by the client software. I put the markings of the *keys* to be *pressed* in succession for the former *with XKB* in quotation marks above. Google Groups as-is is not converting character sequences (and the default display uses a variable-width font, which is unsuitable for Usenet; one of many reasons to use nreasreader software Thunderbird instead), but they could be fixed if you used the unreleased version of my user script (and it would work with the current version of Google Groups – I have to find out where the bug is before I can publish it). The current release which has (had?) only basic features can be found here: <https://github.com/PointedEars/userscripts#ggformatteruserjs> (At the very least you have to use "html-blob" for the “selector” variable instead now.)

What kind of "scientist" are you, fucking stupid, not even an engineer, knowing nothing about Numerical Analysis, Math Modeling, Scientific Computations, Schemes, Recipes, Algorithms and such. You fucking uneducated and unskilled idiot.

You fucking uneducated and unskilled idiot. Hotel and high rise janitors call themselves "engineer" as do street sweepers. Something similar is at work here.
