Freedom of Science

Jimmy Wales wrote: “Look for other exciting announcements in the coming months as we collectively work to free the judgment of information from invisible rules inside an algorithmic black box.”
He was referring to his new search engine  that will use human editing like Wikipedia to fine-tune results as opposed to “algorithmic black box” used by […]

Wikipedia has a nice Cavendish experiment page. There is a reference to a scale drawing of the pendulum. They raised the floor to give Cavendish enough room to make observations. As seen from the section drawing the telescope is too low and it would have been very uncomfortable to make observations.

I started the Freedom of Science blog to free science from the hereditary monopoly of professional physicists. The task is the same as trying to free justice from the hereditary monopoly of another group of corrupt professionals, the lawyers. The relation of lawyers to justice is the same as the relation of physicists to science.

Has physics made a quantum leap from the 18th century to the 21st? Are we witnessing physicists finally dropping distribution and evaluation methods invented by people wearing authority wigs in favor of online discussion? It appears so.
Consider this paper called An exceptionally simple theory of everything. Rather than going through traditional channels of slow moving […]

Doctor Lisi’s successful campaign earned him that great honor the news media reserves for physicists: the new Einstein.
His peers who also covet the New Einstein title now hate him and will unleash a series of commentary thrashing the content of the paper. Big mistake. What the media giveth science cannot take back. Once canonized forever […]

I’ve been working on the equation of motion for the Cavendish pendulum. The motion is similar to torsional harmonic oscillator equation but with the addition of torque term for gravity 2GMmd/(a-x)^2.
My source is this document. The solution is based on the assumption that the excursion of the arm x is much smaller than the distance between weights a […]

As a response to my inquiry someone offered the following papers as modern experimental values of G:
Measurement of Newton’s Constant Using a Torsion Balance with Angular Acceleration Feedback Jens H. Gundlach and Stephen M. Merkowitz
A rotating torsion balance experiment to measure Newton’s constant J H Gundlach
New technique for measuring Newton’s constant G J. H. Gundlach, E. […]

These are the days of the week Cavendish made his 17 observations.1
Monday: 0
Tuesday: 1
Wednesday: 5
Thursday: 6
Friday: 3
Saturday: 0
Sunday: 3
More info on experiment dates.
We can guess why Cavendish did not experiment on Mondays. Cavendish was a recluse and his only social affair was going to Royal Society meetings and dinners. He read his paper reporting the […]

Nigel Cook writes in Quantum gravity mechanism and prediction that
Cavendish produced a more accurate evaluation of G by measuring the twisting force (torsion) in a quartz fibre due to the gravitational attraction of two heavy balls of known mass located a known distance apart.
1. Cavendish did not know about G.
2. Cavendish never measured the Newtonian […]
