Block quotes are
written like so.

They can span multiple paragraphs,
if you like.

Note again how the actual text starts at 4 columns in (4 characters
from the left side). Here’s a code sample:

# Let me re-iterate ...
for i in 1 .. 10 { do-something(i) }

1
2
3
4
5
6

import time
for i in range(10):
    # (but not *too* quick)
    time.sleep(0.5)
    print i

Inline math equations go in like so: $omega = dphi / dt$. Display
math should get its own line and be put in in double-dollarsigns:

$$I = int rho R^{2} dV$$
