The only way I can think to honor Lange is to tell you a bit more about his most famous work. BOOMERang stands for Balloon Observations Of Millimetric Extragalactic Radiation and Geophysics, and it's essentially a balloon-borne telescope designed to make measurements of the cosmic microwave background radiation - the "afterglow" of the Big Bang that still pervades our universe. The first flight, in 1997, concentrated on North America, while two subsequent flights in 1998 and 2003 circled the South Pole.
Based on this data, the BOOMERang team made the most detailed map of temperature fluctuations in the CMB - at least as of April 2000, when the first results were announced. (Science always marches on.) The CMB is pretty smooth, so those fluctuations are tiny, with differences of 1 part in 100,000, and hence very difficult to measure.
Those fluctuations provided the "seeds" that eventually grew into the gigantic galaxies, galaxy clusters and cosmic structures we see in the cosmos today. What BOOMERang did was to measure the size of those fluctuations in angular measure (degrees). I'll let these folks explain why that's significant:
