Absolute Uncertainty and Relative UncertaintyIf a measurement is written as a best estimate plus/minus an uncertainty, this uncertainty is itself an absolute uncertainty. The measurement would most probably lie in the range of the best estimate plus/minus this uncertainty. The relativ...

Delta v = 5.79 xx 10^(5) ms^(-1)What is the uncertainty in velocity of an electron if the uncertainty in its position is 10^(-10) m? Mass of the electron is 9.1 xx 10^(-31) kg and h = 6.6 xx 10^(-34) m^(2) s^(-1)?
The concept of measurement is discussed. It is argued that counting process in mathematics is also measurement which requires a basic unit. The idea of scale is put forward. The basic unit itself, which are composed of the infinitesimal of uncertainty quantum, can be regarded as infinite in an...

Heisenberg Uncertainty Principle According to this principle, the electron wave function is complete and it is not able to predict the exact behavior of any electron. This principle is applicable to very small objects like electrons and prot...
physics that physical phenomena are uniquely tied to actions by deterministic causal laws, and that observables are independent of the observer. Until the statement of the uncertainty principle, Modern Physics held to that idea of a classical determinism, and the rejection of such determinism became...
Recently a feed-forward model was put forward to account for the phenomenon of context correlations (observed by Miyashita and by Yakovlev et al) to replace the attractor picture developed for these findings. It is argued that the new proposal misses the main issues posed by the experimental si...
Therefore, assuming unitarity in black hole evaporation, the standard results suggest that the largest uncertainty in the future quantum state of the universe is due to the Hawking radiation from evaporating black holes. However, the entropy of the matter precursors to astrophysical black holes is ...
What would 675.91785 \pm 0.078727\ mm^3 be into cm with its respective uncertainty? What is the uncertainty of a physics lab? What does uncertainty mean? Length is measured as 9490 cm +/- 40 cm. What is the relative uncertainty?
