Possible to grow a tree from a branch?

When you snip off a branch off a tree, stick it in soil, will the branch grow roots?

I place a branch from Kieffer pear tree in a flower pot with potting soil to keep it from compacting, and make sure the soil is wet. Then, keep it in a shaded area with minimum sunlight. I didn't use the rooting hormone, but it starts to grow tiny green leaves and new roots in a month. Amazing!

Some simple techniques:

This is my new 'Kieffer' pear tree (European, semi-drawf).
Kieffer's detail infomation:
Kieffer's (Pyrus communis) flowers are fragrant, attractive to bees, butterflies and/or birds, self-fertile. Average Water Needs; Water regularly; do not overwater. Fruit in 3-5 years. Kieffer has a crisp, juicy, white flesh that has a coarse texture. It is a consistent, heavy bearer that ripens late September-October, and it is highly resistant to fire blight. Kieffer Pear is very hardy and tolerates hot climates. It will produce medium to large rich-yellow pear, and since the pulp of the Keiffer pear is rather coarse and hard, it is preferable for pear preserves, and freshly cooked pear sauce.
