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
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
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
A sheer mathematical genius
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
A large no of manuscript copies of
"Gaṇita-sāra-saṅgraha"whr discovered in Kerala shows it's popularity
Further he was one of the first mathematician to have given an approximate expression for the circumference of an ellipse(aayata vritta)
He clearly mentioned in his work that a "negative number cannot have a square root" . This is the first remark on clear recognition of the imaginary quantities in mathematics .
More from Science
@mugecevik 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).

I've recently come across a disinformation around evidence relating to school closures and community transmission that's been platformed prominently. This arises from flawed understanding of the data that underlies this evidence, and the methodologies used in these studies. pic.twitter.com/VM7cVKghgj

Speech Delay is most common in children nowadays
In ancient times, our grandparents used to follow typical natural way of caring the needs of a child. All they used were more of natural products than chemical based for the growth of child.
One of major step followed was to feed Gurbach Jadd/ Vasa Kommu/ Acorus Calamus for initiating good speech ability in a child. This stem was needed to babies on Tuesdays and Sundays in mother's milk.
Vasa is feed to baby after the 1st bath on 12th day in week. Weekly only thrice it is fed and named as :
Budhwar - Budhi Vasa
Mangalwar - Vaak Vasa
Ravi Vaar - Aayush Vasa
This stem is burnt and rubbed against the grinding stone in mother's milk or warm water to get a paste
The procedure to make it is in the link

It should not be given daily to the child. Other main benefits are
1. It clears the phlegm in child's throat caused due to continuous milk intake. It clears the tracts and breathing is effortless.
2. Digestion
For children who haven't got their speech and is delayed than usual should feed this vasa on these days in week atleast for 6months. Don't get carried away with this dialogue
"Some gain speech little late"
