Leapsa de voci

I was tagged by Simona, with the "vocal tag" ("leapsa vocala"). Hmm, 3 of my favourite voices in romanian music industry? Simplu .. (not the band) ;)

1. Andra (and here)
2. Holograf
3. Celia

Tag goes further to Bianca and Marius :)

The intellectual "tag, you're it" :))

I was tagged by Marius. Here are the rules:

1. Take the book that is the closest to you.
   
2. Open it at page 123.
3. Find the fifth sentence (including).
4. Post the text of the following 4 sentences on your blog.
5. Don't dare to search for that very special or "intellectual" book through your bookshelf.
6. Pass "it" to 6 friends.
   

The book I always carry in my backpack is "Fundamentals of Computer Graphics" by Peter Shirley and at page 123 you can read:

These days, postmultiplication using column vectors is fairly standard, but in many older books and systems you will run across row vectors and premultiplication. The only difference is that the transform matrix must be replaced with its transpose. The transpose A(T) of a matrix A is one whose rows are switched with its columns.

Tough book, but interesting if you can understand all the mathematical concepts. I hope I will pass the exam :P

Later edit: I tag you, the one that read this post. If you pass it on, write a comment.
