Gravity’s Shadow

According to the theory of relativity, we are constantly bathed in gravitational radiation. When stars explode or collide, a portion of their mass becomes energy that disturbs the very fabric of the space-time continuum like ripples in a pond. But proving the existence of these waves has been difficult; the cosmic shudders are so weak that only the most sensitive instruments can be expected to observe them directly. Fifteen times during the last thirty years scientists have claimed to have detected gravitational waves, but so far none of those claims have survived the scrutiny of the scientific community. Gravity’s Shadow chronicles the forty-year effort to detect gravitational waves, while exploring the meaning of scientific knowledge and the nature of expertise.Gravitational wave detection involves recording the collisions, explosions, and trembling of stars and black holes by evaluating the smallest changes ever measured. Because gravitational waves are so faint, their detection will come not in an exuberant moment of discovery but through a chain of inference; for forty years, scientists have debated whether there is anything to detect and whether it has yet been detected. Sociologist Harry Collins has been tracking the progress of this research since 1972, interviewing key scientists and delineating the social process of the science of gravitational waves.Engagingly written and authoritatively comprehensive, Gravity’s Shadow explores the people, institutions, and government organizations involved in the detection of gravitational waves. This sociological history will prove essential not only to sociologists and historians of science but to scientists themselves.

@tdverstynen It recently occurred to me that I can tell many grad students "I've been doing fMRI research since before you were born"
@elight I'm not familiar with the wastewaterscan site, but CDC has recent data for DC here https://covid.cdc.gov/covid-data-tracker/#wastewater-surveillance and the neighboring Montgomery County data are here: https://www.montgomerycountymd.gov/covid19/data/wastewater-surveillance.html

I have just been notified by @moderation that a toot that justifies the massacre of Israeli civilians does not violate the server's code of conduct. As a member of this cooperatively governed instance, I propose we change the https://wiki.neuromatch.io/Code_of_Conduct to include under "Unacceptable behavior": "Threats or justifications of violence against civilian populations"
Code of Conduct - neuromatch

@timnitGebru Maybe others reported you too, but I did report. I did not report you over using the word "apartheid" nor your other toots talking about Israeli violence. I reported because you wrote "The audacity to call this “unprovoked.”" In what other context would it be ok to say someone was "provoked" to rape and massacre people?

@NicoleCRust Two possibly contradictory things: 1. More stable research jobs where people won't get fired for not getting grants (hard money). 2. More grant funding.

I don't think the issue is specifically about funding high-risk, high-reward. It's that we have little clue what research will be high reward and the more research that's funded the more likely some will lead to major discoveries.

The trouble is that increases in overall grant funding leads to places like UPenn creating more soft-money positions. A big Q for me is how to give universities an incentive to internally support more stable jobs.

@HarryTuttle Maybe the collaborations between Gentry Lee & Arthur. C Clark? (Lee discusses their collaboration here: https://www.jpl.nasa.gov/podcasts/on-a-mission-season-1/season-4-mars-rovers/episode-12-secrets-of-the-mars-rovers )
Episode 12: Secrets of the Mars Rovers

In this season 4 finale, Gentry Lee and Rob Manning reveal how surprises, hidden flaws, and uncertainties have always been a part of rovers and the exploration of Mars.

@tdverstynen Nice work! I just skimmed, but plan to read in more detail. From the interpretation perspective, is the assuming that signal that predicts heart rate with a lag is likely neural in original while signal that predicts heart rate with close to zero lag vascular in origin?

6 thought provoking questions posed to @awaisaftab (psychiatrist) and myself (brain researcher) and we hit on so much:

The challenge of escaping reductionism. Theories of consciousness. Are mental disorders brain disorders? Why should anyone care about philosophy? Is epistemic iteration is failing? And what bits of brain research are awaiting their Copernican moment?

With nods to @summerfieldlab, @knutson_brain, @tyrell_turing, @Neurograce, @eikofried and so many more.

Read it all here (and let's discuss)!

Check it out! Dr. Cole Korponay just uploaded a preprint of our new paper with Dr. Amy Janes. This is a really intriguing finding that seems to have been hiding in plain sight in pretty much every dataset we’ve looked at so far…
