Thrilled to announce our new paper by Victoria Junquera and Adrienne Grêt-Regamey, "Assessing livelihood vulnerability using a Bayesian network: a case study in northern #Laos”, is now out in @ecologyandsociety1 https://t.co/tEbZmiulDS #openaccess #WomenInSTEM. Short thread👇

Some 1300 years ago in Karnataka there lived a genius who wrote "Gaṇitasārasan̄graha" (which is earliest text devoted entirely to mathematics)

The man who's work later borrowed by Arabs & Europeans

Thread on "Mahāvīracharya" astounding but forgotten legacy

Mahāvirachārya was patronised by rashtrakuta king amoghavarasha

His book"Gaṇita-sāra-saṅgraha"is earliest text devoted entirely to Mathematics

He has described the currently used method of calculating(LCM)of given numbers.The same method was used in Europe later in1500CE

Mahavira wrote "Gaṇita-sāra-saṅgraha" (GSS) in 8th century CE which contains some 1100 slokās & contains elementary topics in arithmetic , algebra , geometry , measurements , logic , number theory , dynamical systems etc

A sheer mathematical genius

He was devout jain
His magnum opus "Ganit sara sangraha " start with a sloka bowing to the glory of the jinas

"संख्याज्ञानप्रदिपेन जैनेंद्रन महत्वेशा,
प्रकाशितम जगतसर्व येन तम प्रणमाम्यहम"

He also praised his predecessor aryabhata , brahmagupta & other greats in his works

The importance & popularity of "Gaṇita-sāra-saṅgraha"was so huge that it enjoyed statues of most important textbook of mathematics in South Indian for over 3 centuries

A large no of manuscript copies of
"Gaṇita-sāra-saṅgraha"whr discovered in Kerala shows it's popularity

Here's more on the new mitigation scenario for 1.5C. How does it work? What would society look like? Are we willing to do what's required to stop climate breakdown? See thread.

1. Most models assume we need to keep growing the economy indefinitely. The problem is this makes it impossible to transition to zero emissions quickly enough; so they speculate on geoengineering and negative-emissions technologies to save us. Scientists reject this as too risky.

2. By contrast, this scenario proposes that high-income countries don't *need* more growth, and can scale down unnecessary production and consumption. This reduces energy demand (from 140 EJ in 2020 to 40 EJ in 2050), and enables a rapid transition to renewable energy.

3. What does it require? In the global North (Annex 1 countries)
•a shift from private cars to public transportation
•reduction in flights
•smaller average house size

Meanwhile, consumption in the global South (non-Annex 1 countries) rises to converge.

4. Significant reduction of aggregate material use. How? Longer product lifespans; regionalization of production and consumption; ban on advertising; a shift in taxes from labour to resources. All of this allows us to reduce ground freight, which cuts energy use.

Why English as the Universal Language of Science Is a Problem for Research

Where do most of the researchers and inventors around the world appear today? What is their mother tongue?
1/8

The obstacle to many researches in our country is that many of the documents and research articles that they need to do research are available in English only 80-90%.

Can't anyone read and understand research articles so easily? Why is that?
2/8

Today most scientific papers are published in English. What is lost when other languages ​​leave?

Plagiarism in research articles Should not be. What is Plagiarism?
3/8

Plagiarism is the representation of another author's language, thoughts, ideas, or expressions as one's own original work.

In educational contexts, there are differing definitions of plagiarism depending on the institution.

Quite a surprise. Ferguson isn’t qualified to comment on such things. He lacks understanding of basic biological concepts, partly explaining why his predictions are often so extreme.

That said, I’ll take him as an ally. It’s clear we’re already at herd immunity. How can I be sure? London had a huge peak of excess deaths in spring. The timing of peak deaths showed clearly that the pandemic was self-limiting. Recall much debate about whether the interval...

...between lockdown & peak deaths was long enough for lockdown to have been the cause of reducing deaths? The answer was “no”. But it was close & I can understand people thinking “well, it’s close, so perhaps it was lockdown that did it?”, thereby establishing a foundational...

...myth favoured by those who genuinely believe lockdown saves lives (it clearly doesn’t).
I’ll get to London & here immunity. But those wavering about the evidence about lockdown in spring really will benefit from cogitating on this graph.

In blue are the 30 trusts with the earliest date of peak deaths in spring. In red, the 30 with the latest peak deaths. For me, this is proof that national lockdown, which began Mar 23, played no role whatsoever in turning the pandemic. You’ll see some areas had peak daily...
