I'm sure part of it is that EE claims probably the widest range out there. You can have kilovolts or microvolts, but mostly the same rules apply. Or you can learn how to power a small sensor for years off one small battery, or how to power a country. I don't know many other disciplines that can lay claim to 10-15 orders of magnitude.
At most levels, software will be in there somewhere, even those fake flickering candle LEDs have RAM, ROM, and a processor these days.
I feel like astronomy probably wins, the magnitudes are literally astronomical.
The Perseus Cluster of galaxies is estimated[0] at something like 816,592 light years in diameter, so that's 10^21 meters, and on the other end 2008 TC3[1] is an asteroid 4.1m across.
