    External walls are the best place for a radiator typically.

    The majority of the heat lost from your room will be via the surface which has the largest temperature difference on the other side from in temperature from the room. More so if windows are installed.

    The heat is lost in 2 ways, cold air infiltration into the room (thro small cracks in the window frame or vents) and the building fabric being cooled by the outside air as the cold fabric will absorb the heat form the room.

    Putting the radiator on that surface helps both by mixing the cooler air coming in with the warmer room air preventing drafts and also maintaining the surface temperature high enough to prevent condensation forming which can lead to mould etc..

    Yes, but it doesn't turn corners. I'm not the only person I know who has a staircase that as you go up, you can feel your head enter a different and colder climate... :D

    The design criteria for the placement of radiators dates back a good bit. It was when there was only radiant panel rads and floor standing casts. They were put under the windows because it was the coldest spot.
    It didn't take into account modern convection rads, double or tripple glaze windows or insulated walls.

    I have a modern house with good insulation and none of my rads are on window wall's or external wall's. The place is toasty.

    In college we are still thought to place them under the windows.
