New England Journal Of Medicine On What Masks Can’t Do Regarding SARS-CoV-2

BY Herschel Smith
8 hours, 23 minutes ago

Do you recall that I said this?

Next up, the wearing of masks.  I have some experience in air filtration engineering from my early career testing and balancing HEPA filters and charcoal adsorbers.  HEPA filters (of concern here) work by particle interception due to electrostatic force.  Surgical masks, cloths, handkerchiefs, and other manner of cotton material (cotton is cellulose) do not have that.

My daughter wears one in surgery and the ER to prevent potential blood-borne pathogens from entering her mouth, not to prevent SARS-CoV-2, flu or the common cold (which is also a Coronavirus).  N95 masks are just that, 95% efficient for particles down to a given size.  Moreover, when a nuclear or chemical worker wears a full face respirator, if the wearer is a male and has a beard, he must shave.  Workers have tried to create work-arounds for this by glazing their face with Vaseline, but the seal never works.  The bulk of breathing air goes around the filtration media if there is no testable seal, not through it.  This is true of full face respirators, and it is true in the superlative for these silly little masks half of America is wearing.

When you put an N95 mask on, the bulk of your breathing air is going under and over the top of the mask, not through it.  Furthermore, every decontamination technique eventually destroys the electrostatic charge on the fibers, thus rendering the mask useless.  It’s designed to be worn and then thrown away.  It’s actually worse than useless, because we are now learning that there is a heavy viral and pathogenic loading on both the outside and the inside of the filter media, and we also now know that the degree to which a patient suffers from this disease is a function – at least partially – of the amount of inoculate that you breath.

Then I got a little more detailed and discussed particle sizes.

HEPA filters will remove particles down to 0.3 µm in size (to usually 99.95% efficiency, depending upon the filter – here I have used data for nuclear grade filters).  The SARS-CoV-2 virus is 80 nm in diameter.  A few viruses out of a million might be intercepted by electrostatic force, but that’s essentially zero.

If the particle you’re trying to intercept is spittle, stay away from coughing people anyway.  But those particles drop by sedimentation, diffusiophoresis, etc.

0.3 µm versus 80 nm.  A nanometer is 1E-9 meters, and 1 µm is 1E-6 meters.  This means that a SARS-CoV-2 virus is 80E-9 / 0.3E-6 = 0.27 the minimum size necessary for even the most expensive nuclear grade HEPA filters to remove it from an air stream.

I need to caveat these statements and observe that because of the serpentine flow of air through a HEPA filter, it’s possible that there is some removal efficiency due to electrostatic force (i.e., that it’s not zero), assuming a charge on the shell of the virus.  But it’s still low.  While I’m not perfect, I won’t mislead readers.  And while there is some small probability that there will be some small effect, any very small particulate eventually re-evolves into the air stream.

One of my major gripes with how America has turned to the medical bureaucracy during this pandemic is treating medical doctors like experts in every field of science.  They’re not.  A doctor isn’t an air flow and filtration engineer.  A doctor isn’t an industrial hygienist.  A doctor isn’t a physicist.

But it’s still nice to see that eventually they conform to the truth of what science tells us.  This is straight from the New England Journal of Medicine (nejmp2006372).

We know that wearing a mask outside health care facilities offers little, if any, protection from infection. Public health authorities define a significant exposure to Covid-19 as face-to-face contact within 6 feet with a patient with symptomatic Covid-19 that is sustained for at least a few minutes (and some say more than 10 minutes or even 30 minutes). The chance of catching Covid-19 from a passing interaction in a public space is therefore minimal. In many cases, the desire for widespread masking is a reflexive reaction to anxiety over the pandemic.

You can read the rest for yourself.  They eventually dive into a discussion concerning the use of masks by medical workers, and I think over-state their case (I still believe, along with my daughter, an NP, that she wears a mask for purposes of protecting herself from blood-borne diseases and spittle in the OR and ER).

However, nits here and there shouldn’t obfuscate the fact that at least they are being honest about this.  Anxiety is the root of the problem, and reflexive fealty to the priesthood of the medical profession is a symptom of real problems in America concerning the lack of STEM education and knowledge.

Concerning The Effectiveness Of Masks To Filter SARS-CoV-2

BY Herschel Smith

Remember that I said this to you?

Next up, the wearing of masks.  I have some experience in air filtration engineering from my early career testing and balancing HEPA filters and charcoal adsorbers.  HEPA filters (of concern here) work by particle interception due to electrostatic force.  Surgical masks, cloths, handkerchiefs, and other manner of cotton material (cotton is cellulose) do not have that.

When you put an N95 mask on, the bulk of your breathing air is going under and over the top of the mask, not through it.  Furthermore, every decontamination technique eventually destroys the electrostatic charge on the fibers, thus rendering the mask useless.  It’s designed to be worn and then thrown away.  It’s actually worse than useless, because we are now learning that there is a heavy viral and pathogenic loading on both the outside and the inside of the filter media, and we also now know that the degree to which a patient suffers from this disease is a function – at least partially – of the amount of inoculate that you breath.

I’m certainly not perfect, but I won’t mislead you.  I stumbled upon this video and thought it might be enlightening that someone else thinks the same way.

This information is true because: HEPA filters will remove particles down to 0.3 µm in size (to usually 99.95% efficiency, depending upon the filter – here I have used data for nuclear grade filters).  The SARS-CoV-2 virus is 80 nm in diameter.  A few viruses out of a million might be intercepted by electrostatic force, but that’s essentially zero.

If the particle you’re trying to intercept is spittle, stay away from coughing people anyway.  But those particles drop by sedimentation, diffusiophoresis, etc.

You’ll have to forward to about five minutes in the video to get past the rambling. I think some inspired readers could add to all of this by linking video or citing URLs where Fauci now claims that the wearing of masks is merely a sign of respect.

Paul Cottrell Interviews Judy Mikovits

BY Herschel Smith

I’ve had some requests to address the detractors to this woman and her claims from readers, and I’ve seen them myself.

It would be highly involved for me to address each and every accusation against Ms. Mikovits, since I have a lot of observations to make, from the silliness of some of the peer review I have actually experienced myself in professional publications, to the character attacks (this is called the genetic fallacy [or it could be characterized as ad homineim attacks], and it’s a formal logical fallacy), to completely ignoring the substance of her arguments, to trying to criticize from the perspective of not really understanding what epidemiological studies are all about and how they’re conducted (there is a gargantuan difference between an epidemiological study for, say, worker exposure to Benzene or Isocyanates, and something like SARS-CoV-2). Before quitting, I’ll also say that there is a huge difference between trying to get points across in a 30 minute video intended for the non-scientific masses, and a more detailed conversation like this. I understand the difference. Some people are too stupid to do that. Some of my own readers complain when I write two-minute reads, some complain when I write one-hour long prose. I can’t write a book every time I write (and supply every caveat and qualification) and you can’t please everybody.

Perhaps I’ll catalog all of my responses at some point, but in the interest of allowing her to answer her critics herself, here it is.  It’s long (some 2.5 hours).  But if you hear any detractors in the future, ask them one single question.  Did they listen to this entire video and do they have an answer for everything she said, in order, one by one, in detail?  If not, you should summarily dismiss their criticism.

Covid Coding

BY Herschel Smith
1 week, 4 days ago

Telegraph.

The Covid-19 modelling that sent Britain into lockdown, shutting the economy and leaving millions unemployed, has been slammed by a series of experts.

Professor Neil Ferguson’s computer coding was derided as “totally unreliable” by leading figures, who warned it was “something you wouldn’t stake your life on”.

The model, credited with forcing the Government to make a U-turn and introduce a nationwide lockdown, is a “buggy mess that looks more like a bowl of angel hair pasta than a finely tuned piece of programming”, says David Richards, co-founder of British data technology company WANdisco.

“In our commercial reality, we would fire anyone for developing code like this and any business that relied on it to produce software for sale would likely go bust.”

More.  “The code on which they based their predictions would not pass a cursory review by a Ph.D. committee in computational epidemiology.”

You had one job and couldn’t do it because you suck.  I don’t suck at my job.

Covid-19 Is A Laboratory Engineered Virus

BY Herschel Smith

Word is getting out.  I told you this from the beginning, and if you believed me, you believed the truth from the beginning.  You can blame this mess on Anthony Fauci, Big Pharma, the NIH, the NIAID, Bill Gates, and Fort Detrick (among others).

As for the rampant desire to control others, that finds its basis in Genesis Chapter 3. The desire to control others is the signal pathology of the wicked.

Can We Trust Covid Modeling?

BY Herschel Smith
2 weeks, 1 day ago

Sweden.

H. Sjödin et al: ‘Covid-19 health care demand and mortality in Sweden in response to non-pharmaceutical (NPIs) mitigation and suppression scenarios’, 7 April. The graph suggests critical care demand would peak above 16,000 patients per day by early May, and pre-pandemic intensive care unit capacity would be exceeded 30-fold.

Then came J. Gardner et al, ‘Intervention strategies against Covid-19 and their estimated impact on Swedish healthcare capacity’, 15 April.  It was an even more pessimistic assessment, showing a peak of over 20,000 patients by early May – with an ICU requirement around 40 times the actual capacity.

Sweden’s Public Health Agency rejected the models. It instead planned for a worst-case scenario that was much less pessimistic, suggesting a peak around 1,700 ICU patients in the middle of May. Still more than three times more than the pre-pandemic capacity. Sweden, almost alone in the world, refused to lock down. And here is how things eventually worked out.

The number of patients in ICU has been fairly stable around 500-550 since mid-April. This means that capacity was never exceeded. At this moment, when the models suggested that Sweden would have 30 to 40 patients fighting over every available ICU bed, there is spare capacity in beds, equipment and personnel of around 30 percent (partly as a result of a doubling of the pre-pandemic capacity).

No.

We can’t trust your models because all of your models suck.  They suck because the ones building the models suck.

I know science.  I do science every day.  This isn’t science.  I don’t suck at my job.

A very enlightened and enlightening conversation.  I’ll also mention yet again that Paul discusses the necessity of Vitamins C and D3 if you want a healthy immune system, something we’ve seen elsewhere.

What Do Bill And Melinda Gates, The World Bank, Big Pharma, And The Global Preparedness Monitoring Board Have In Common?

An awful lot.  This is a very important video, conveying very important research into the machinations of the global health mafia and their demanded protection money.

Oh, make sure to be able to answer this question when you’re finished.  Who said this: ” … conducts at least two systemwide training and simulation exercises, including one covering the deliberate release of a lethal respiratory pathogen?”

Dozens Dead After Lockdown Measures Delayed Their Heart Surgeries

BY Herschel Smith

News from the land of Trudeau.

“A report has been released today by UHN with respect to cardiac deaths and it has been estimated that approximately 35 people may have passed away because their surgeries were not performed,” Health Minister Christine Elliott acknowledged last Tuesday, according to Toronto Star.

[ … ]

“We feel for those families who have lost family members whether it has been from cancer deaths or cardiac deaths or a COVID-19 death, but these were decisions that we had to make,” she said, adding, “That’s not something any of us want to hear. It certainly was not intended. Any death is a tragedy.”

Sure it was.  You knew what you were doing and you did it anyway.  That makes it intentional.

Coronavirus: How We Got Here

This is a very important video.  I assume that mother-Google will take it down soon.  Watch this entirely as soon as you can. I watched this one hour ago, and it had just over 700,000 views. Now it has close to one million.

But they won’t be able to shut her up.  She has a book.

EDIT: Mother Google has already taken it down. Let’s see if this works.
