As a physicist I can show you Leipzig from a scientific point of view:

•     Which Nobel Prize winners lived and worked in Leipzig?
•     What was Werner Heisenberg working on in the Physical Institute?
•     Why did the universal genius Gottfried Wilhelm Leibnitz leave his hometown Leipzig?
•     Why do you see so rarely buildings with a concave facade like the City High Rise ?
•     What has the Old City Hall to do with the Golden Section and how is it defined?
•     Where and how the fine dust concentration is measured?

You can also book a combination of walking tour with the main stress on science.
