A new #Cochrane Review on physical interventions against respiratory viruses is making the rounds. The review focuses exclusively on #RCTs and finds that in the entire scientific literature, there are 78 studies with a bearing on the various questions asked. (1/n)

@ndloubere Great to open this discussion, IMO. I was not aware of the censorship and data selling issues - sounds like major problems. I think the most enthusiastic OA supporters imagined the present model to be an intermediate step towards what's now called "platinum OA", but AFAICS there is not much momentum for making platinum the standard.

Check out our intervention in @univlararen outlining the ways in which the corporate publisher-friendly Open Access model represents a drain on public resources, and argues for time, energy, and support for ethical, non-profit Open Access.
Every physicist has a copy of Goldstein's book on Analytical mechanics in his/her bookshelf. I don't share the conviction but have to love his cockiness about Bohmian mechanics around the 12 minute mark here:

Fauci's Inductive Risk:
“When he downplayed mask efficacy to prevent hoarding, Fauci arguably manipulated the public.” But can his position be defended using an argument from inductive risk - using different levels of evidence depending on whether hypotheses align with political or other extra-epistemic goals? Eli Lichtenstein argues "no."

@johncarlosbaez that blog post is a true joy to read and look at.

Does a uniformly accelerated charge radiate? One would say yes, but there has been a debate in the context of relativity. Uniform acceleration should be the same as a uniform gravitational field, and then you would not expect an observer who is co-accelerated to be able to detect any radiation field.
Turns out, there are no contradictions in the end!
Here is the electric field intensity in the (x,z) plane, with the charge coming in from infinity and accelerated back towards infinity.

At PREreview we offer a platform that allows authors to post a preprint and request a review, so long as the preprint has a DOI. Reviewers sign up using their unique
@ORCID_Org credentials and are able to select a public or anonymous persona for their reviews.
When a review is submitted it is assigned a DOI which enables reviewers to cite the work in their portfolios when applying for jobs, promotions, or grants.

@freemo thanks for looking into to it
@freemo wow, that's a quick reply :) IMO, provisionally turning it off would be helpful.
LaTeX formatting often becomes unreadable on #qoto. Often a single character is resized to enormous size compared to the rectangular box a typical toot fits into, and this hides a lot of the containing toot. This happens frequently with posts from mathstodon.xyz. @freemo, if others have this problem too, would it be possible to turn off LaTeX formatting until it's fixed? Seeing the raw, unformatted LaTeX code would be an improvement.

@ct_bergstrom Do you think there should be a single set of global moderation rules? Or, e.g., country specific or language specific rules?

A disturbing (and beautifully done) graphic and story by #Reuters on #insects. Makes you wonder... https://www.reuters.com/graphics/GLOBAL-ENVIRONMENT/INSECT-APOCALYPSE/egpbykdxjvq/ via @joostvkasteren
Expose of the weak man fallacy, meaning selecting (for refutation) the weakest argument for a position.
It is useful with a standard name for this one as it is committed by nearly everyone in public debates.

Just 600 years ago, nine species of enormous, flightless birds called moas wandered around New Zealand. Some of these magnificent big birds grew up to 12 feet tall, which would tower over Sesame Street’s most famous resident.
Moas had thrived for millions of years. And suddenly - shortly after humans arrived on the islands - they went extinct.
Coincidence? #Science says no. https://www.science.org/content/article/why-did-new-zealands-moas-go-extinct #nature
