is an excellent scientist and a responsible professional. She likely read the paper more carefully than most. She grasped some of its strengths and weaknesses that are not apparent from a cursory glance. Below, I will mention a few points some may have missed.
1/

 The paper does NOT evaluate the effect of school closures. Instead it conflates all ‘educational settings' into a single category, which includes universities.
2/
The paper primarily evaluates data from March and April 2020. The article is not particularly clear about this limitation, but the information can be found in the hefty supplementary material.
3/
The authors applied four different regression methods (some fancier than others) to the same data. The outcomes of the different regression models are correlated (enough to reach statistical significance), but they vary a lot. (heat map on the right below).
4/
The effect of individual interventions is extremely difficult to disentangle as the authors stress themselves. There is a very large number of interventions considered and the model was run on 49 countries and 26 US States (and not >200 countries).
5/
It is challenging to estimate the effect of interventions in the absence of a counterfactual. This difficulty is compounded by likely confounders, such as climate (not mentioned in the paper). Territories that implemented similar interventions might share comparable climate.
6/
This is a sophisticated piece of work, with both strengths and weaknesses. Though, to me, its primary value is the proposed methodological framework rather than its estimates of the efficacy of individual interventions, which efficacy remain debatable.
7/
There is room for scientific discussion about how solid the estimates presented in the paper may be. Though, accusing colleagues expressing reservations about the robustness of some of the findings of 'spreading disinformation' feels inadequate, to say the least.
8/
This paper has generated endless conflict. One intriguing feature is that all the spats are around 'educational settings'. Interestingly, the paper also claims that T&T and isolation of cases, among other measures, are completely ineffective, yet no one seems to care ... 🤔

JUST IN: The U.S. National Climate Assessment is now public.

This is the report that the Trump Administration doesn’t want you to see. Years in the making, released on the day after Thanksgiving. #ClimateFriday

Here are some of the main

This report is mandated by Congress and focused on the impacts of climate change in the U.S.

Basically: This is what our best scientists think will happen to us as a result of the actions our government is (not) taking to address the most important problem in human history.

Fellow academics, when are we going to start fixing our urgent structural problems that strain family bonds and present ongoing barriers to diversifying our educational and scientific leadership? You wonder, what the heck is this guy talking about?
1/n

We’re all very familiar what I am talking about, actually: the impossibility for most academics in the life sciences to do their jobs in a reaonable amount of time, due to more and more demands on writing grants, and to a lesser degree, papers.
2/n

As of yesterday I hadn’t intended to write about this subject, but was wondering as I finished a Saturday of straight work, what happened to all my time? Why has WFH not reduced my pile of tasks to do? Instead why is my to-do list growing bigger and bigger?
3/n

I decided to figure out how much time our jobs actually require. I estimated per year (m=month, w=week, d=day, h=hour):
Teaching: 20h/w x 20w = 400h
Meetings of all sorts: 10h/w x 48w= 480h
Replying to email: 2h/d x 365d = 730h
Attending and giving talks: 2h/w x 50w = 100h
4/n

Papers: If each person needs 2 papers during a 5y stint, and you run a 7.5-person lab, then you need 7.5 papers per 2.5y = 3 papers/y. Throw in a review and it’s 4 papers. If you need 15d at 8h/d per paper, that’s 480h writing papers.

11 BIG IDEAS OF PHYSICS

via @BlasMoros of @LTCWRK

(Thread 👇)

1. Galilean Relativity

We can never fully grasp, define, or understand a system we are part of.

“Distance provides perspective” and wisdom in life is often about perspective.

2. The Laws of Thermodynamics

The study of the large-scale behavior of systems exchanging work and heat with connected systems or their environment.

- The Transitive Law

- The Law of Conservation

- The “Contrast Advantage” Law

- The “Absolute Zero” Law

3. Newton’s Laws of Motion

Describe how objects in the world move and react to forces.

- The Inertia Law: An object at rest, stays at rest

- Force = Mass * Acceleration (F = ma)

- The Law of Reciprocity: For every action there is an equal and opposite reaction

4. Complexity

A complex system exhibits emergent behavior due to the collective interaction of many individual agents according to simple rules.

Complex systems are sensitive to original conditions, influenced by feedback loops, and buffeted by random outside variables.

1/ Automobiles and Intake Fraction. Since cars are back in the news I thought I would retweet this model result I offered in early April 2020. I focused only on 1 micron particles & accounted for windows completely closed & cracked slightly open.


2/ Related air exchange rates were based on experimental results in literature for mid-sized sedans. Particle deposition to indoor surfaces were accounted for, as the surface to volume ratio in a 3 m3 cab is large. An important outcome was the intake fraction (IF)

3/ Here, IF is the number of particles (or virions in collective particles) inhaled by a receptor DIVIDED BY the number or particles (or virions in collective particles) emitted by an infector.

4/ Integrated over the two hour drive (in this example) the IF for all windows closed & a receptor at rest is 0.08 (8% of what comes out of the infectors respiratory system ends up in the respiratory system of the receptor). 8%! That is a very high intake factor.

5/ With additional ventilation from cracking a window open drops the IF to 0.012 (1.2%) still relatively high. Can get lower by opening more windows.

So it turns out that an organization I thought was doing good work, the False Memory Syndrome Foundation (associated with Center for Inquiry, James Randi, and Martin Gardner) was actually caping for pedophiles. Uhhhh oops?


Since this, bizarrely, turned out to be one of my longest videos ever (??) here's a quick thread to sum it up for those of you like myself with short attention spans. 1/10

In the '90s the False Memory Syndrome Foundation was founded to call attention to the problem of adults suddenly "remembering" child abuse that never actually happened, often under hypnosis. Skeptics like James Randi & Martin Gardner joined their board. 2/10

A new article reveals that the FMSF was founded by parents who had been credibly and PRIVATELY accused of molestation by their now-adult daughter. They publicized the accusation, destroyed the daughter's reputation, and started the foundation. 3/10

The FMSF assumed any accused pedo who joined was innocent, saying "We are a good-looking bunch of people, graying hair, well dressed, healthy, smiling; just about every person who has attended is someone you would surely find interesting and want to count as a friend" 😬 4/10

The 2018 State of JavaScript survey is out. They got 20,000 responses and have some delicious, delicious data. I'mma thread in some highlights:

First up: JavaScript flavors. There's TypeScript at 47% adoption, a tad higher than npm's own survey results (which said 46%). npm's survey is coming up again soon and will ask about TypeScript in a lot more detail.


I really, *really* like SoJ's "would not use again" question, which lets people who've abandoned a tech self-identify. This is noticeable in the graph above with Flow users -- 41% of people who've used Flow say they wouldn't use it again.

Now JavaScript frameworks. It's been a full year since npm's survey, so these numbers differ from ours in the directions I expected:
React 65% (vs. 60%)
Vue 29% (vs. 24%)
Ember 5% (vs 4%, I was expecting a bigger rise)

But there's a shocker in here: Angular.


npm's survey had Angular at 40% last year and SoJ has it at either:
- 58% (if you include those who don't want to use it again)
- 24% (if you count only those who like it)
Since npm's question didn't ask if they intend to *continue* using it I think that might explain this.

#தினம்_ஒரு_திருவாசகம்
தொல்லை இரும்பிறவிச் சூழும் தளை நீக்கி
அல்லல் அறுத்து ஆனந்தம் ஆக்கியதே – எல்லை
மருவா நெறியளிக்கும் வாதவூர் எங்கோன்
திருவாசகம் என்னும் தேன்

பொருள்:
1.எப்போது ஆரம்பித்தது என அறியப்படமுடியாத தொலை காலமாக (தொல்லை)

2. இருந்து வரும் (இரும்)


3.பிறவிப் பயணத்திலே ஆழ்த்துகின்ற (பிறவி சூழும்)

4.அறியாமையாகிய இடரை (தளை)

5.அகற்றி (நீக்கி),

6.அதன் விளைவால் சுகதுக்கமெனும் துயரங்கள் விலக (அல்லல் அறுத்து),

7.முழுநிறைவாய்த் தன்னுளே இறைவனை உணர்த்துவதே (ஆனந்த மாக்கியதே),

8.பிறந்து இறக்கும் காலவெளிகளில் (எல்லை)

9.பிணைக்காமல் (மருவா)

10.காக்கும் மெய்யறிவினைத் தருகின்ற (நெறியளிக்கும்),

11.என் தலைவனான மாணிக்க வாசகரின் (வாதவூரெங்கோன்)

12.திருவாசகம் எனும் தேன் (திருவா சகமென்னுந் தேன்)

முதல்வரி: பிறவி என்பது முன்வினை விதையால் முளைப்பதோர் பெருமரம். அந்த ‘முன்வினை’ எங்கு ஆரம்பித்தது எனச் சொல்ல இயலாது. ஆனால் ‘அறியாமை’ ஒன்றே ஆசைக்கும்,, அச்சத்துக்கும் காரணம் என்பதால், அவையே வினைகளை விளைவிப்பன என்பதால், தொடர்ந்து வரும் பிறவிகளுக்கு, ‘அறியாமையே’ காரணம்

அறியாமைக்கு ஆரம்பம் கிடையாது. நமக்கு ஒரு பொருளைப் பற்றிய அறிவு எப்போதிருந்து இல்லை? அதைச் சொல்ல முடியாது. அதனாலேதான் முதலடியில், ஆரம்பமில்லாத அஞ்ஞானத்தை பிறவிகளுக்குக் காரணமாகச் சொல்லியது. ஆனால் அறியாமை, அறிவின் எழுச்சியால், அப்போதே முடிந்து விடும்.

You want to buy a house.

You take a loan from the bank.

The bank asks you, “what if you don’t pay back?”

You say, “take my home and sell it”.

(Thread)

That makes sense. The bank gives you a loan and in case you don’t pay, the bank will take over your house and sell it and recover its money.

That’s collateral.

Banks also lend money to big corporations. With them, banks don’t always have collateral.

So a loan where the bank has collateral is considered safer for the bank.

In the early 2000s, the banks in the USA were giving out loans to people for buying houses.

The economy had just recovered from the tech bubble in 2000 where many banks had given out loans to businesses that had shut down.

In that backdrop, the banks found giving home loans safer.

SRI LALITHAMBIGAI, THIRUMEYACHUR (TN)
#bharatmandir #navratri2021

Kshetram where Shiva is worshipped as Meghanatha and his consort is Lalithambigai seen in Abhay mudra.
Once, a demon Pandasura was harassing the Devas who went to Devi Parashakti for protection. 
@GunduHuDuGa


Devi rose from a Yaga Gunda, mounted on the Sri Chakra Rath with the name Lalithambika, waged a war against Pandasura and destroyed him.  When her fury did not subside, Shiva asked her to go to Earth, assume the name Manonmani, perform penance and shed her fury.


Shiva blessed Devi to be Shanta nayagi. There is a sculpture here depicting Shiva pacifying Devi. If you observe closely, you can see that from your left hand side there will be a smile on Her face and if you see from your right hand side you can see anger in Her face.


Hayagriva taught the greatness of Lalitha Sahasranama to Rishi Agasthya. Pleased with his devotion, Ma Lalithambikai appeared before Agastya. He is believed to have then sung Lalita Navaratnamala in praise of Devi. He has also composed a hymn named Rahasyanamasahasram.
