Right now, during a world-wide pandemic, many of us cannot do what we usually do, and so we take the opportunity to do something for our education. You may be one of the many people who have extra time at hand these days, and I want to support your desire to use this time to learn and assist you by telephone and via email. I guarantee that you will get a lot of enjoyment out of it! Here is what I have to offer...
Language Classes for Professionals
Language Classes for Advanced Speakers and Intermediary Students
Conversation: topics from science, technology, art, business, philosophy...
Selected Topics in Linguistics (Englisch, German, Japanese)
Selected Topics in Electronics; also Amateur Radio Exam Prep Classes
One of my specialties is knowledge transfer (consulting, teaching, mentoring, presenting, etc.), and I started using the telephone in that context about 35 years ago, to provide software support. The audio quality of phones is much better today, notably when using VoIP: my providers are "voip.ms", "iptel.org", and "sipgate.de" and the audio codecs I typically use are "Opus", "G.722", and "G.726".
