The uncertainty principle [PDF]

open access: yesNature, 2004
Sociologist Ray Oldenburg believes that everyone needs three places: home, work and a 'third place'. In the United States, the third place is, increasingly, the coffee shop. In Britain, it is without doubt the pub. And in Finland, it's the sauna, as I learned the other month while visiting the country.

Generalised uncertainty relations from finite-accuracy measurements

open access: yesFrontiers in Astronomy and Space Sciences, 2023
In this short note we show how the Generalised Uncertainty Principle (GUP) and the Extended Uncertainty Principle (EUP), two of the most common generalised uncertainty relations proposed in the quantum gravity literature, can be derived within the ...

The Uncertainty Principle [PDF]

open access: yesNature, 1933
THE familiar application of this principle is to a particle, such as an electron, and from it we learn that errors, q in the positional co-ordinate and p in the momentum, must occur such that: "q “p h.

ON GRAVITY AND THE UNCERTAINTY PRINCIPLE [PDF]

open access: yesModern Physics Letters A, 1999
Heisenberg showed in the early days of quantum theory that the uncertainty principle follows as a direct consequence of the quantization of electromagnetic radiation in the form of photons. As we show here the gravitational interaction of the photon and the particle being observed modifies the uncertainty principle with an additional term.

On Majorization Uncertainty Relations in the Presence of a Minimal Length

open access: yesPhysics, 2022
The emergence of a minimal length at the Planck scale is consistent with modern developments in quantum gravity. This is taken into account by transforming the Heisenberg uncertainty principle into the generalized uncertainty principle.

Biotechnology's Uncertainty Principle [PDF]

open access: yes, 2003
In theory, we have a unified patent system that provides technology-neutral protection to all kinds of technologies. However, we have recently noticed an increasing divergence between the rules actually applied to different industries. Biotechnology provides one of the best examples.

Uncertainty, joint uncertainty, and the quantum uncertainty principle

open access: yesNew Journal of Physics, 2016
Historically, the element of uncertainty in quantum mechanics has been expressed through mathematical identities called uncertainty relations, a great many of which continue to be discovered.

On the Uncertainty Principle [PDF]

open access: yesAmerican Journal of Physics and Applications, 2016
Analysis of the laws which form, direct universe and of the interacting elements in the interactions emerging by these laws. Forming the theoretical, philosophical infrastructure of the some physical concepts and phenomena such as kinetic energy, uncertainty, length contraction, relative energy transformations, gravity, time and light speed to ...

The uncertainty principle: Variations on a theme [PDF]

open access: yesBulletin of the American Mathematical Society, 2021
We show how a number of well-known uncertainty principles for the Fourier transform, such as the Heisenberg uncertainty principle, the Donoho–Stark uncertainty principle, and Meshulam’s nonabelian uncertainty principle, have little to do with the structure of the Fourier transform itself.

Extended Uncertainty Principle black holes

open access: yesPhysics Letters B, 2019
An Extended Uncertainty Principle inspired Schwarzschild metric that allows for large scale modifications to gravitation is presented. At a new fundamental length scale L⁎, the usual black hole characteristics (horizon radius, ISCO, and photosphere ...
