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
Mahāvira was the world's first mathematician to give the general formula for n C r in combinations .

Further he was one of the first mathematician to have given an approximate expression for the circumference of an ellipse(aayata vritta)
Mahāvira also made an important remark in connection with "root of negative number" .

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 .
He was the first one to write arithmetic in present day form , he described in details the current method of finding lowest common multiple. therefore, it was an invention not by John napier but by our very own scholar mahaviracharya in its actual form.
Mahaviracharya work was an important link in the continuous chain of Indian mathematics ,it acquired pride place particularly in South India

His work was recognised by great chalukyan ruler Raja Raja narendra who got it translated in telugu by mathematician pavuluri mallana
The credit tht Mahavira rightly deserves for discovery of various methods in the field of mathematics hs gone almost unnoticed by historians

Mahavira by his sheer achievements in several branches of mathematics has a distinct position in the history of indian & world mathematics

Hugh Everett's birthday! Pioneer of the Many-Worlds Interpretation of quantum mechanics. Let us celebrate by thinking about ontological extravagance. I will do so by way of analogy, because I have found that everyone loves analogies and nobody ever willfully misconstrues them.


We look at the night sky and see photons arriving to us, emitted by distant stars. Let's contrast two different theories about how stars emit photons.

One theory says, we know how stars shine, and our equations predict that they emit photons roughly uniformly in all directions. Call this the "Many-Photons Interpretation" (MPI).

But! Others object. That is *so many photons*. Most of which we don't observe, and can't observe, since they're moving away at the speed of light. It's too ontologically extravagant to posit a huge number of unobservable things!

So they suggest a "Photon Collapse Interpretation." According to this theory, the photons emitted toward us actually exist. But photons that would be emitted in directions we will never observe simply collapse into utter non-existence.
Epic thread incoming:

I'm going to answer the question so many people have been asking this week:

WHAT IS PROJECT X???

Here's the definitive thread to tell you - and show you -precisely what Project X is

Grab a drink, sit down with me and let's #TalkLiberation

"Project X" is actually called "PanQuake".

Pan means "all". Quake is the huge effect our voices can have when our communications are uncensored and when we have access to brand new functionality that *enhances* our social reach, rather than diminishes it

SPOILER ALERT: Much of the content below this point is from my personal slides & speech notes from today's launch event. That stream got totally ruined by (big) tech problems, but I'm happy to report everything is turning out wonderfully


Here are some of our most high profile & dedicated public advocates for PanQuake - many of whom were scheduled to appear at our launch. All of whom stuck around for hours, to do a prerecord of the event, which is being edited, processed & uploaded for you as I write this.
