The vaccine-reluctant

Published by marco on

From a comment on the article, Vaccine Success, Media Misery: Is Good News Taboo in the Trump Age? by Matt Taibbi (TK News)

“I find it interesting that for all the takes on who will and who won’t take the vaccine- and why- a simple reason is commonly overlooked: For many people in good health and of a certain age group, the virus poses little to no real threat. Yes, there have been terrible cases reported in surprising victims, but as far as the data goes, they continue to be anomalies.”

This is exactly the kind of... [More]

Drosten’s prediction: 100% immune (vaccinated or infected, take your pick)

Published by marco on

Virologist Christian Drosten was very good on his weekly podcast, (88) Impfmission possible by Das Coronavirus-Update von NDR Info (Apple Podcasts). In this episode, he lays down the cold facts: COVID will become endemic in the west. Get vaccinated or get COVID. There is no choice (C).

An English translation follows the German citation.

At 48:00,

Christian Drosten: Jeder wird immun werden. 100%. Nicht 70% oder 80% sondern 100% in der Bevölkerung werden unweigerlich—ich würde mal sagen, in einem Fenster das von jetzt noch so anderthalb Jahre... [More]”

Is COVID-19 really over in the west?

Published by marco on

Biden recently informed the nation that things would be back to normal by July 4th—as if the virus cares.

Biden peddles national self-delusion on pandemic anniversary by Patrick Martin (WSWS)

“The language of collective loss, suffering and sacrifice, however, ignored the brutal fact that one section of American society, the super-rich, has lost nothing at all from 12 months of the worst pandemic in a century.

“While 527,000 Americans died, the billionaires increased their wealth by $1.4 trillion. While the economy... [More]”

Muddling through the misinformation

Published by marco on

The article CDC study finds c. 78% of people hospitalized for COVID were overweight or obese by Mark Crispin Miller contains the following text and the link below it.

“A study from the CDC, reported by CNBC, and yet it slipped right down the memory hole, despite—or because of—the further light it sheds on the entire COVID narrative, which has millions of slim, healthy people tightly masked and terrified of human contact.”

Coronavirus-Update #82: Die Lage ist ernst by NDR Ratgeber (YouTube)

Drosten’s pissed. I’ve heard “irreführende” about 90 times now. He thinks there are two options: let it rip and collapse the health system or go back into lockdown (“der Holzhammer”) … Germany doesn’t seem capable of doing anything in between.

He said “private Kontakte” are definitely where infections are coming from now. It’s no longer true that “wir wissen einfach nicht wovon die Infectionen kommen…”

At 37:30, he said

“Bei keinem diesen Viren gibt es eine “Dauerwelle”. Der Begriff “der... [More]”

COVID-19 updates with Herr Doktor Christian Drosten (de)

Published by marco on

Vor einem Jahr habe ich zum ersten mal von Herr Doktor Christian Drosten erfahren. Heute höre ich nahezu wöchentlich seinen Podcast mit Moderatorin Korrina Hennig auf Staatssender NDR mit. Er ist beruflich Virologe und kann sich sehr gut nicht nur über das Thema sondern auch die mit der Pandemie damit verbundenen gesellschaftlichen und politischen Themen diskutieren und verständigen lassen.

The Science of Free Will and Behavior

Published by marco on

The podcast episode 134 | Robert Sapolsky on Why We Behave the Way We Do by Sean Carroll (Wondery) was a really interesting introduction/look at the science of free will as described in far greater detail in his book Behave (which I have not yet read).

 Robert M. Sapolsky's BehaveI’ve included a partial transcript of the parts that I found the most interesting. The following comes from the end of the episode, where they both did an excellent job of summarizing the preceding discussion’s points as well as pointing out logical conclusions for e.g.... [More]

Waiting it out

Published by marco on

People’s behavior vis á vis COVID-19 at this point—ten months after the onset of the virus—is like when an action movie’s hero is in the swamp with a straw in his mouth, sucking a barely adequate supply of air through it, while his pursuers are still somewhere up there, looking for him.[1]

Were they still within earshot? Would they hear him if he just came up quickly for a good, solid breath? Were they completely gone? Was he suffering underwater for nothing? They’re not still around, right?... [More]

Radio vs. Sound Waves

Published by marco on

I played Kahoot[1] the other day with the family. The quizzes are pretty wide-ranging and pretty decent fun, especially for a mix of ages. One of the quizzes concerned sound and electromagnetic waves and I tried to explain why one of the answers was incorrect “in the moment”, as it were. Concerned that my explanation had engendered rather than answered questions, I take another crack at it below.

The WHO on Facemasks and Pre-symptomatic Contagion

Published by marco on

Facemasks

The article Here’s what WHO says your mask should have to prevent COVID-19 spread by Beth Mole (Ars Technica) details the technical specifications for making your own facemask.

tl;dr: “you’re probably doing it wrong, guidance suggests.”

The WHO says:

  • “[…] masks should only ever be used as part of a comprehensive strategy in the fight against COVID.”
  • “WHO now recommends that healthy members of the public wear homemade or commercially-available fabric masks in places where the new coronavirus is circulating... [More]

German virologist Christian Drosten

Published by marco on

Professor Christian Drosten is a virologist working at the Charité University Hospital in Berlin. Since the beginning of March, he’s been doing an informative podcast in German called Coronavirus-Update. I’ve found him to be highly informative and factual in a world filled with propaganda, conspiracy theory and shoddy science.

The following interview with Drosten was one I found in English, which he also speaks fluently. I thought the 30 minutes, in particular, were very enlightening... [More]

China vs. the US: A Global Chronology of Covid-19

Published by marco on

The article Tomgram: Dilip Hiro, The Coronavirus Chronology From Hell by Dilip Hiro (Tomgram) provides an excellent and impartial review of the four months of history we have so far. In particular, he contrasts America’s inchoate response with the measured and ostensibly empathetic reaction of China. China reacted by increasing production capacity of PPE, masks, and ventilators.[1]

“By mid-March, the Chinese government and the Jack Ma Foundation, part of the giant corporate conglomerate Alibaba Group, had sent doctors... [More]”

Facemasks (Listening to Experts)

Published by marco on

Everybody’s talking about ‘em: facemasks. Which kind? Where can you buy them? How do you get your outsized ass to a hospital that needs them? Should you wear one? Should everybody? Which kind? In which situations?

The beleaguered CDC

The lynching party seems to be out in the States for the CDC, which is being blamed for trying to kill everyone by telling them that they don’t need facemasks. This is the same advice being given the world over by anyone qualified to have an opinion.

World-o-Meter Coronavirus Tracker

Published by marco on

I’ve settled on using the Coronavirus (World-o-meter) tracker. It seems to update relatively quickly and reasonably accurately and is also well-sourced. About a week ago, they finally added two new columns: total tested and tested/million people, which helps you compare the case numbers of countries more accurately (i.e. if a country has no cases and is testing like mad, then that’s good news; if they have few tests, then you can’t really conclude anything, but it’s probably not good news).

For Switzerland,... [More]

COVID Info (Single Source)

Published by marco on

The interview The Tip of the Iceberg: Virologist David Ho (BS ‘74) Speaks About COVID-19 (Caltech) includes the following:

Why different symptoms? Mutated strains?

No.

“This virus is mutating but it has mutated very little so far. There are differences but probably they are functionally not important, so that’s not the explanation for why you see different disease courses among the infected.”

Can you get re-infected?

No.

COP25 in Madrid

Published by marco on

The 25th COP (Conference of the Parties) or United Nations Climate Change conference (Wikipedia) has come to an end in Madrid. Other instances of this conference were COP3 in Kyoto (the first agreement that the U.S. agreed to and which the Congress completely ignored), COP 15 in Copenhagen (where Canada and the United States worked together to torpedo any agreement) and, of course, COP21 in Paris, with the much-touted Paris Accords that Obama signed and that Trump officially left—and which all other...

CO2 output per year continues to increase

Published by marco on

The article Here’s how much global carbon emission increased this year by Scott K. Johnson (Ars Technica) includes some sobering, if utterly unsurprising charts.

Not Even Close

This first chart is the most sobering one: it shows that we’ve most likely[1] slowed our CO2 production from 2018 to 2019. But we’re still increasing. That is, it’s a positive development, but not nearly enough.

 % increase in fossil-fuel usage

We need to get to zero CO2 emissions by 2050 (or maybe even 2040) in order to avoid completely nightmarish scenarios. With the CO2 we’ve... [More]

The Nuclear Option

Published by marco on

The other day, I responded to I’ve read the actual reports on Chernobyl. I’ve worked in the nuclear industry by TracyMorganFreeman (Reddit) with three comments.

Nuclear is a Sane Option

The linked comment jibes with my other reading (outside of Reddit, heaven forfend) on nuclear power and safety, as well. E.g. there’s Soonish
The Lost Chapter, Advanced Nuclear Power
(SMBC). It’s a relatively clean power source with a worse reputation than it deserves—on paper.

Unfortunately, the industry that’s attached to it is an absolute... [More]

Evolution takes eons

I am in no way doubting evolution. I am simply admitting that my mind cannot truly encompass the chasm of time required to build this creature incrementally.

Chinese land a rover on the dark side of the moon

Published by marco on

The article China makes history by landing on the far side of the Moon by Eric Berger (Ars Technica) has pretty exciting news.

“a Beijing-based control center commanded the spacecraft to begin the landing procedure at 9:15pm ET Monday (10:15am, Tuesday, local time), from an altitude of 15km above the lunar surface. During an 11-minute descent, Chang’e-4 slowed its speed from 1.7 km/s to nearly zero before it landed in the Von Karman Crater in the South Pole-Aitken Basin.”

This is a science mission, but I’m really hoping... [More]

Recycling of e-waste at only 20% worldwide

Published by marco on

The article Just 20 percent of e-waste is being recycled by Scott K. Johnson (Ars Technica) provides a good overview of the global recycling situation, based on a recent report from the United Nations’ International Telecommunication Union.

As you would expect, amount of recycling and waste produced per region differs considerably.

“Africa, for example, accounted for only about five percent of the total e-waste generated—roughly zero of which was recycled. Europe and Russia combined to generate about 28 percent of the... [More]”

Choosing an electoral system

Published by marco on

Americans have, once again, noticed that the electoral college is odd. And undemocratic. And odd.

There are much more democratic systems out there. “First past the post” is not one of them. YouTube and CGP Grey to the rescue.

The Trouble with the Electoral College by CGP Grey (YouTube) and Re: The Trouble With The Electoral College – Cities, Metro Areas, Elections and The United States by CGP Grey (YouTube)

Sean Carroll on Physics and Death

Published by marco on

This is a video by the always-interesting and funny Sean Carroll on physics (naturally) and on things that we know about life, death, entropy and the afterlife. It’s a really interesting talk that is very technically deep while still being more accessible than other, similar talks.

Emperor Has No Clothes Award Acceptance Speech by Sean Carroll (YouTube)

Near the beginning, he addresses heaven and the afterlife and the explanations that non-scientists have embraced.

Big data ignores lessons learned

Published by marco on

The article Big data: are we making a big mistake? (Financial Times) bursts the bubble of the wide-eyed, overconfident and underinformed techies who think that their giant piles of data will fix everything. The article contains many interesting examples, some of which are touched on in the conclusion, cited below:

“Uncanny accuracy is easy to overrate if we simply ignore false positives, […] The claim that causation has been “knocked off its pedestal” is fine if we are making predictions in a stable... [More]”

On the nature of addiction

Published by marco on

Perhaps uncharacteristically, this post will consist mostly of citations of other articles about the nature of addiction. I have relatively little contact with addiction, but the truth of what these ex-users write is evident to anyone of a rational bent who is reasonably informed about the world.

The article Philip Seymour Hoffman is another victim of extremely stupid drug laws by Russell Brand (Guardian) writes,

“People are going to use drugs; no self-respecting drug addict is even remotely deterred by prohibition.”

Is Fukushima radiation polluting the entire Pacific Ocean?

Published by marco on

Take a deep breath. Step back. Does that sound plausible? Is the mighty power of the atom, harnessed by decades-old technology, likely to be able to effect such mighty change?

Because the Pacific Ocean is huge. Like, really gigantic. It has 16 times as much surface area as the entire United States of America. Hell, there’s a Pacific Garbage Patch whose estimated size is about the surface area of the US of A and we can barely even tell it’s there.

Dara Ó Briain: a comedian…for science

Published by marco on

Dara Ó Briain is London-based Irish comedian with a show on BBC2 called Dara Ó Briain’s Science Club. His act is a good deal bawdier on stage though the focus remains on promulgating a pro-science agenda. In the segment below, he discusses a show he did with physicist Brian Cox in which the topic of astrology just happened to arise.

Some choice tidbits from this segment:

“The astrologers get going on Twitter and write, ‘if you were really a scientist, then you’d be more open-minded.‘ And I... [More]”

Radiation is everywhere! (And we’re all gonna die.)

Published by marco on

A story of Fukushima radiation is making the rounds, reported variously as Navy sailors have radiation sickness after Japan rescue by Laura Italiano and Kerry Murtha (NY Post) and 70+ USS Ronald Reagan Crew Members, Half Suffering From Cancer, to Sue TEPCO For Fukushima Radiation Poisoning by Brandon Baker (EcoWatch) (with a re-post at AlterNet). Other source cited in the articles are the Washington Times and FOX News, paragons of journalistic integrity.

Modern nature documentaries

I was recently sent this link, presumably because I enjoy short nature documentaries.

Man vs. Wild − Eating Giant Larva by Bear Grylls (YouTube)

Some thoughts:

  • Do larvae really get bigger the older they get? Isn’t a larva a limited stage of development? How is it that some are so much larger than others? Isn’t it more likely to be related to food intake rather than age?[1]
  • People are weird. If Bear were to eat fluffy baby animals (say chicks) rather than slimy ones (larvae in this case), he would be drummed off the air.

Remaining reserves

Published by marco on

The article NASA’s Plutonium Problem Could End Deep-Space Exploration by Dave Mosher (Wired) discusses a resource shortage that will be hard to address: plutonium.

Plutonium was produced in much larger quantities during the nuclear-arms race of the mid to late 20th century. Though the arms race was morally reprehensible and fantastically expensive, a byproduct was that there was more plutonium available for scientific endeavor. Pound for pound, it is unparalleled as a long-lasting energy source. As of the end of... [More]
