Professor Åström helped me with my Master Thesis at Lund's Technical Highschool in the early 80s, a nice man who had a lot of patience with me. I still remember the Nyquist diagram. K-J Åström is 83 y old when this was recorded - amazing! He has more energy (and hair) than me! Hi Karl-Johan, I hope you are doing fine!

Seems to be really humble man, though I tried to understand his book during my Masters but my Math was so weak, I will give it another try soon.
