Far better than NAB carts, and much cheaper too. I assume you mean 8-tracks - they aren't quite the same. And what about Compact Cassette? They were quite good once improvements were made to the tape and heads &c. Too bad DAT wasn't allowed because of DRM and consigned to computer data storage. -- Max Demian |

I've just put up an alternative layout of the book
http://jcgl.orpheusweb.co.uk/Informa...DF_Book_pf.pdf This makes more use of an A4 page's area. And now includes the section page numbers in the 'Contents' list.

Your document now has fewer pages and a smaller filesize. -- Dave W |

Can be obtained from http://jcgl.orpheusweb.co.uk/Informa...t_PDF_Book.pdf [snip] I would like to thank Jim for making this book available and to comment that it seems ungrateful to criticise layouts and pagination. OTOH I suppose all the regulars know each other on this group and such observations may not be unexpected. :-) It does indeed seem ungrateful, but if I'd written the book I would be eager to know about any defects in case I could do something about them. Now Jim has done that. -- Dave W |

The book was largely based on some of the lecture courses I gave at St Andrews. You can see individual lectures and sections of the later versions of my I and M course here https://www.st-andrews.ac.uk/~www_pa...ndm/intro.html The uni continued to keep my 'Scots Guide' pages available because they and others use it as a teaching resource. But, having retired, my old uni email address no longer works, despite still being on the web pages. The top page for the site's URL is in my sig, below. There were other courses, but not all the pages are linked to it. Research-level stuff tends to go stale faster than the basics. :-) Jim -- Please use the address on the audiomisc page if you wish to email me.

wrote: I can imagine some students might sign up for this and find more maths than they expected. Well, I suppose it's no bad thing to grind a bit of rigourous thought into young minds. FWIW One of the reasons I wrote the book was that most of the existing alternative texts had far *more* maths per page, and less explanatory text! The result was books which even *lecturers* failed to understand, but felt "must be good" because it looked impressive. Example of the story of two people coming out of a talk, one saying to the other: "He must be clever, I didn't understand a word he said!" 8-] Sadly, this also means that many of the textbooks I found on IT and also EM contained erronious arguments or 'proofs' which had been duly copied from one book to another. Presumably because generations of authors didn't understand but assume it "must be correct". However the maths I used should be quite within the grasp of an honours student in physical science or engineering. Tools of the trade. Although I do wonder if people now use computer programs without a clue how they work. Jim -- Please use the address on the audiomisc page if you wish to email me.

Industry standard from the 60s until MD based systems came along to replace them. Today of course HDD based/servers are used -- Mark Please replace invalid and invalid with gmx and net to reply. |
