     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.

     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.

     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.
