Induced gravitational waves as a probe of thermal history of the universe [PDF]

open access: yesJournal of Cosmology and Astroparticle Physics, 2020
The scalar perturbation induced gravitational waves are a probe of the primordial density perturbation spectrum on small scales. In this paper, we show that they can also probe the thermal history of the universe. We assume the universe underwent a stage

Overcoming the Newtonian Paradigm: The Unfinished Project of Theoretical Biology from a Schellingian Perspective [PDF]

open access: yes, 2013
Defending Robert Rosen’s claim that in every confrontation between physics and biology it is physics that has always had to give ground, it is shown that many of the most important advances in mathematics and physics over the last two

Using the Wigner-Ibach Surmise to Analyze Terrace-Width Distributions: History, User's Guide, and Advances [PDF]

open access: yes, 2006
A history is given of the applications of the simple expression generalized from the surmise by Wigner and also by Ibach to extract the strength of the interaction between steps on a vicinal surface, via the terrace width distribution (TWD).

Supersymmetric Unification [PDF]

open access: yes, 1994
The measured value of the weak mixing angle is, at present, the only precise experimental indication for physics beyond the Standard Model. It points in the direction of Unified Theories with Supersymmetric particles at accessible energies. We recall the

Evolution of quasi-history of the Planck blackbody radiation equation in a physics textbook

open access: yesAmerican Journal of Physics, 2018
In physics textbooks, the emphasis is normally placed on the physics. In order to give the subject a deeper dimension, the inclusion of history and persons involved in the development has been increasing.

A selected history of expectation bias in physics

open access: yes, 2005
The beliefs of physicists can bias their results towards their expectations in a number of ways. We survey a variety of historical cases of expectation bias in observations, experiments, and calculations.Comment: 6 pages, 2 ...

History of dark matter

open access: yesReviews of Modern Physics, 2018
Although dark matter is a central element of modern cosmology, the history of how it became accepted as part of the dominant paradigm is often ignored or condensed into an anecdotal account focused around the work of a few pioneering scientists.
