A second is defined a a measure of time. The article defines time as, "The duration of exactly 9,192,631,770 periods of the radiation corresponding to a hyperfine transition of caesium-133 in the ground state." Seconds are waves produced from atoms. A second is known as a ticking which measures atomic time. A standard clock measures frequency, stability, and accuracy. It uses atomic time to measure standard time. Time was standardized by syncing frequencies to create regularity and stability.
Do you think all standard clocks are actually in sync with each other?
ReplyDeleteHi Kacie!
ReplyDeleteI find it interesting that they were able to come up with a definitive answer for defining time when just last week we were reading theories that time is actually an illusion. Regardless, I feel like our measurement of time is wrong if we're looking at frequencies of the atom. I mean, if the atom must be in ground state and that rarely happens, how are we actually getting an accurate calculation. After all of the information we have been given, has your opinion on whether time is real or unreal changed? and if so why?
