   • 2011, Barry Allen, Superman 709‎:

     I can think at the speed of light, I can perceive events that last for less than an attosecond, I can run faster than time. What do I see when I run across the country, Superman? I see everything. And everyone.

Wittmann, H. Schröder, P. Tzallas, D. Charalambidis, O. Razskazovskaya, V. Pervak, F. Krausz, L. Veisz, “Next Generation Driver for Attosecond and Laser-plasma Physics”, in Scientific Reports, volume 7, →DOI:

     The observation and manipulation of electron dynamics in matter call for attosecond light pulses, routinely available from high-order harmonic generation driven by few-femtosecond lasers.

   • 2023 January 10, Adam Rogers, “Move over, megatons”, in Business Insider‎, archived from the original on 20 August 2023:

     Given the scales on which technology has operated in the first quarter of the 21st century, from lasers that flash for just a few attoseconds to the total amount of digital data in the world pushing past 160 zettabytes, it feels as if we may have let things lie for too long. I don't know if the future will have quettabit computer networks or rontometer-scale wormholes, but I'm pretty sure the large and small of it will be hella weird.

   • 2023 October 9, Dennis Overbye, “The Science Nobel Winners Were Short and Fast”, in The New York Times‎, 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.
