A Study of Notation #84:

“…the domain of attosecond measurements begins with Notation 84.”

A report from the Ludwig-Maximilians-Universität, Max-Planck-Institut für Quantenoptik in Garching, Germany (Deutschland), the team of Prof. Dr. Ferenc Krausz leads the world in actually measuring the smallest unit of time. They are down into the attoseconds (10-18 seconds), so their group’s website is appropriately designated: https://www.attoworld.de

A most-prodigious scholar, Dr. Vladislav S. Yakovlev, sent his calculations:

Shorter durations than the Attosecond:

Where the nanosecond is getting better known — one billionth of a second — because it describes standard computer operations today, the picosecond  (10−12) which operates at the one trillionth of a second, is becoming commonplace.

The femtosecond  (10−15) operates at one quadrillionth whereas Garching’s work (10−18) is down within one quintillionth of a second.

1. The Zeptosecond (10−21)

Just one sextillionth of one second, the zeptoscond is still rather slow, 10−21 when compared to Planck Time 10−44. This infinitesimal duration is now the object of laser physicist Martin Schultze of Ludwig Maximilian University measurements. If it is truly a measurement with a device and not just a mathematical calculation, Schultze will have stepped back into the 74th to 77th notations!

2. The Yoctosecond (10−24)

One septillionth of a second (10−24) is a very short duration but a long, long way from Planck Time (10−44). It’s range is from Notations 65 to 67. The words for the six categories down to the Planck scale do not even exist yet! The last International System of Units  (SI) categories to be added were in 1991. It may be time that they ask for some help to name six new groups: 10−27, 10−30, 10−33, 10−36, 10−39, and 10−42.

Fascinating, isn’t it?
