Hello and welcome to digital tea with mr.

Well, we will see what's brewing in the world of physics solutions.
00:06
So in this problem, we're considering homes that have windows on their south sides and what impact that would have on heating and cooling in the home throughout the year.
00:19
So in the northern hemisphere, consider the winter home and where the sun is at during the wintertime.
00:28
The sun rises in the east and sets in the west, but since the earth is tilted away from the sun, that ends up putting the sun lower in the sky as it moves from east to west, and lower in the sky would have it on our southern side.
00:48
So as a result, the light from the sun, or more specifically, the heat from the sun, can flow through the windows and add free solar heating to the home during the wintertime with windows on the southern side.
01:05
Now consider the same principle, but now let's go to summer.
01:09
Now the earth is tilted towards the sun, so that ends up putting the sun higher in the sky, still in our southern sky, but it is certainly higher...
