Yoctonewton Detector Smashes Force Sensing Record 214
KentuckyFC writes "A team of physicists has measured the smallest force ever recorded, at 174 yoctonewtons (yocto=10^-24), beating the previous best by three orders of magnitude. Their measurement device consists of a few dozen beryllium ions trapped in magnetic and electric fields using a device called a Penning trap. These ions vibrate at between a few mega and kilohertz, frequencies that can be accurately measured by bouncing laser light off the ions and measuring any Doppler shift they cause. Being charged, the ions are highly susceptible to the tiny forces associated with stray magnetic and electric fields, which change the frequency at which the ions vibrate. Hence the super-sensitive measurements. They team says that straightforward modifications should allow them to measure single yoctonewtons in the near future. This sudden leap in sensitivity could cause a problem for the system of SI prefixes, which don't yet come any smaller than yocto."

I, hereby, propose the diminewtons.
They should've started from the tiniest entity, like we CSs did with the bits.
They won't hear us complain of not having a name for portions of a yotabit.

Simple. Call them deciyoctos, centiyoctos, miliyoctos, microyoctos, etc. The problem will be solved forever. It's not like we will find anything smaller.

I say that the SI authority open the floor for commercial advertisers to sponsor smaller prefixes.
Future announcements might include: "Physicists break force measurement record with device sensitive to 10 Applenewtons."

Just enough to hold the mandatory 30 second anti-piracy advertisement, followed by the RIAA approved 5 second clip of the song, followed by a 30 second commercial outro.
All DRM protected and only usable with "trusted" hardware (digitally encrypted at receiver and then decrypted by the new mandatory $500 digital speaker, or $200 earbuds) to keep those evil pirates from infringing.

The obvious next steps below Zepto would be Grouchto, Harpto, and Chicto. If they'd followed the logical course they'd be set for another two orders of magnitude, instead of having to come up with a new name in the middle of a recession. Do they think SI prefixes grow on trees or something?
