   • 2023 October 9, Dennis Overbye, “The Science Nobel Winners Were Short and Fast”, in The New York Times‎^[1], archived from the original on 12 October 2023:

     We humans are so stuck in the middle of the cosmic scales — in average height, one-hundredth of one-septillionth (10^-24) the size of the observable universe, and with typical life spans of a couple octillion attoseconds. And an attosecond is an eternity compared with the lifetime of the elusive Higgs boson, a subatomic particle that exists for one-thousandth of an attosecond before decaying.

2. Relating to something that is smaller in scale than the diameter of a hydrogen atom.

   The electron microscope is able to resolve detail at the subatomic level.
