    Thank you so much for this excellent video. I'm trying to optimize my house for solar heating, and I have always had trouble understanding where the sun was supposed to be except at sunrise and sunset. And since I was up at sunrise a couple of days ago near the solstice, I've got a better sense of direction.

    Such a nice lerning video! We'r studying solar tracking in sustainable architecture course & it was very useful to refresh this things. Unfortunately prof's way to do it isn't so simple & clear. Anyway, thank you a lot!

    For Freeman McCoy: It's true that in Northern Hemisphere summer the Earth is tilted towards the Sun. However, that alone won't change where the Sun get's to its highest point in the sky. It has to do with your location on Earth. In the northern latitudes, to face the Sun during the day, you face a southernly direction. It's the opposite for the southern latitudes.

    What's the difference between the path of the sun during the day and the ecliptic?

    Question: In the diagram at 2:30 and following, why is the highest point of the sun on the Summer Solstice in the SOUTHERN sky? I'm confused. With the Earth's tilt on the axis, isn't the tilt toward the sun in the Summer Solstice? Which means it would be in the NORTHERN sky?

    Is it possible to say: Countries south of the Equator the sun's daily trip is an arc across the northern sky - face north. Does anybody have ane diagrams showing this path, please?

    Nice presentation, but's it's northern latitude biased and there are some mistakes. If you were in the southern latitude the concepts would still be correct, but they would be the opposite. When is the longest/shortest day of the year? Errr. I thought all days were the same length.except when there's a leap year?

    I did the sun shadow test a few weeks ago - northern hemisphere in autumn - and the results are as expected. ua-cam.com/video/ti9c8G7Kwio/v-deo.html

    You keep saying path of the sun, so you are not a believer of the heliocentric theory?

      This video is describing the *apparent* path of the Sun, as seen by a viewer on Earth. Earth is certainly in orbit around the Sun. :-)
