I've always been interested in the solar system's natural satellites (or moons), and how varied and unique each one is. We have so many worlds to explore in the future. So, which one do you think is the most beautiful or your favourite? Why?

Can one learn about the structure of something of which one is a small part of the structure and cannot travel far from their home location? If you lived in an apartment but could only look out the windows (and what if every wall of your room does not have a window and you cannot leave the room), how could you tell if you were in the center of a city, town, village or in the middle of "nowhere" or in the "transition region" between the combination of any of the above? You cannot 'make' a window by knocking a hole in the windowless wall...

I need a connection to the structure and our location in the Milky Way Galaxy

I am at work and my window is level with the top of a palm tree right outside my window. There is this large bird - either a crow or a raven (can't tell the difference) I think - and he is hovering/trying to land on the section of the tree below the fronds (where it looks like the base of many fronds that aren't growing). I finally noticed that he is picking into the tree and eating something in there. What is in there? Bugs? Worms? It can't be small birds because I would see it hanging out of his mouth.

x
∫f(t)dt = xe^2x + ∫ (e^-t) f(t)dt
0
for all x, find an explicit formula for f(x)

I'm pretty confused on the layout of the function.
So its adding xe^2x to the integral? and if so how would someone integrate something like this?

(By the way, the second ∫ has the same limits: from 0 to x)
