From Werner KRAUTH

Here are three approaches to reaching my office at 24 rue Lhomond, 75005 Paris:

Contents 1 Algorithmic approach 2 Boy-scout / girl-scout approach 3 Personal-touch approach

Algorithmic approach

If you like algorithms (and chances are up, if you come to talk to me), then follow this 6-step algorithm. If you're really strong, you don't have to print it on paper.

• Enter the ENS physics building on 24 rue Lhomond (a)
• Turn right BEFORE the lobby (b-c)
• Go up the stairs (c) into the green corridor (d).
• Before the glass elevator (d), take the staircase to 1st floor (e) (1 flight of stairs).
• On the first floor, turn to the left twice (f: first turn; g: second turn).
• My office LE110 is on the right (h). While there, please enjoy the view and, I hope, the discussion.

Boy-scout / girl-scout approach

If you have a good sense of orientation, then please ignore the algorithmic approach. Simply memorize the location of my office. It will then be very easy, and quite rewarding to find me out.

Personal-touch approach

Please call me on my cell-phone, and I will come down and pick you up.
