The second video of the issue about why the sun plays cool music is focosing on the sun and climate in particular cloud formation in connection with cosmic rays and condensation cores. Specifically, the so-called Swensmark effect is explainded (in a very simplified matter). Furthermore, the timecourse of the amount of sunspots is shown from the last 400 years. Finally, the Mounder Minimum (small ice age) is highlighted and why the wood of violins from Stradivari plays a crucial role in this matter. Finally, an old violin with more than 100 annual rings is shown and how a climate change can be estimated. In the closing credits, there are some acknowledgements, references including image sources. I appreciate KevinMac Leod, whose music I like a lot.

My slogan Believe little Question everything Think yourself When time allows, there are regular new videos about music and science but also other interesting topics in connection with nature science and medical aspects. My goal is to contribute with my part that people are better informed about specific topics in music and science. The focus is music (e.g. violins), physics (e.g. climate, astronomy) and biology (e.g. viruses, human eye), but also sports (music and moving). If you are interested in these topics and you would like to follow my slogan, than you should subscribe my channel.

Although everyone knows that our earth is rotating in 24 hours intervals, this video try to highlight the earth rotation from outer space and that all type of life on earth is adapted on day-night rhythm (human beings, animals, plants and even viruses). This is the moment one becomes fully aware if things are observed from the outside. The first part of this video underline that the first manned lunar landing on the 20th of July 1969 was the greatest, most dramatic scientific achievement in human history. No rocked was with a height of over 100 m so huge and with 160 million PS so powerful like the Saturn V moon rocket from those days (short video embedded). I myself saw such a Saturn V in the Kennedy Space Center museum in Florida. Amazing! The astronauts are lying (crammed) in a small capsule on the tip of the rocket. Between December 1968 and December 1972, the Saturn V rocked brought 24 astronauts to the moon! (https://de.wikipedia.org/wiki/Saturn_(Rakete)#Saturn_V). It revealed that there are invaluable records from the moon with view on our blue (rising) planet as they could not taken since 1972. This video presentation focuses on the behavior of people and motion profile in time lapse by day and by night, whereby one can see differences depending on the position of the sun (and the weather). Towards evening, the amount of people is reducing. Even in the twilight, one can see that the people switch on artificial light and electricity. In this section, the rotating earth of the dark side is visible, on which the locations with light and electricity are visible. The last part of this video shows the same location at deep night at which some people are still on the way and even the subway is still running. As delicacy, an interesting planet constellation with Saturn and Jupiter is visible, which I have also tracked in time lapse and observed more closely. More specifically, Jupiter with its 4 brightest moons is shown as well as the ring planet Saturn with its rings (whereby uncountable rings could only be dissolved with the help of space telescopes and Voyager 1 and 2). The distance between earth and Saturn is over 1.4 billion km, whereby even the light with 300.000 km/s would need approx. 1 hour and 20 min to earth. Interestingly, almost no people are on the way shortly before sun rise. At that point of time, it is most quiet (and coldest), by which the video also ends, and a new day begins. This playing has been going for many billion years as almost old as the earth is. In the closing credits, there are acknowledgements and source references. In addition, image- and audio sources are listed. Especially, I appreciate Kevin MacLeod, whose music I like.

On 20th of July, there was the first lunar landing, which I could follow in a cathode ray tube television in those days, and I was very fascinating. To date (over 50 years later), many things have been changed. The last moon landing was 1972 with Apollo 17 and I guess that the mankind has already passed its peak at that challenge. When time allows, there are regular new videos about music and science but also other interesting topics in connection with nature science and medical aspects.
