The Mechanical Universe... And Beyond. Early 80's physics visualization documentary / lecture that still holds

When I was a kid this series was shown on swedish television on "utbildningsradion " = education radio. It was television even it was  radio. It had a swedish speaker voice then. Later I found out that it came från Caltech. It's a 52 part series and each part is about 30 minutes long. It explains basics physics from historical context but also explains physics formulas with the help of animations. It was produced in the beginning of the 80's but still holds. And since 2016 Caltech has the complete series on their Youtube channel.
