A word about the nature of mathematics

Mathematics is larger than life. Mathematics is eternal. Technology is ephemeral.

Proclus praises the nature of Math

This therefore is Mathematics. She reminds you of the invisible forms of the soul. She gives life to her own discoveries. She awakens the mind and purifies the intellect. She brings light to our own intrinsic. ideas.

Proclus (412-485 CE)

Math is personal

the yin and yang of enid blyton


Enid Blyton has recently been accused of sexism, racism, xenophobia, homophobia and lack of literary merit. Well! After 70 years, an organization called English Heritage chooses to reappraise her works through the filter of the current value system. Not my circus, not my monkeys, except that I grew up loving her books in faraway India, and feel impelled to speak up.

Even if some of this harsh criticism were deserved, I would say her characters simply reflected the mores of those times, or at least what most ordinary people of that time might have agreed with. As someone who has read her books over and over as a child, and later as a mom, here’s my take.

Sexism: That Georgina of Famous Five wanted to be George was not hard to understand. Growing up with brothers who had more freedom, I could see the advantages of being a boy too!…

remarkably like us!


‘A virus is a small collection of genetic code surrounded by a protein coat’. A human being is a collection of genetic code enclosed in a physical body.

‘Viruses infect cells and use components of the host cell to survive and make copies of themselves’. Human beings live on earth and commandeer its resources to survive and make copies of themselves.

‘Viruses can replicate only inside the living cells of an organism’. Human beings can reproduce only on this planet because earth makes homeostasis – and therefore life – possible.

‘Often, they kill the host cell in the process, and cause damage to the host organism’. Often, they destroy essential elements of the earth in the process, and cause damage to the host planet.

In other words, our lungs are home to the corona virus just as the earth is home to us, and it seems we…

perhaps a silver lining


I got my second vaccine dose yesterday. I’m done for now, but who knows how the final vaccination schedule will pan out, with newer strains, or variants of concern as they are called, still proliferating. These vaccinations could turn out to be an annual ritual. I’ve stopped questioning. What’s the point anyway?

A genuine accident, an act of carelessness, supreme recklessness, a deliberate plan, whatever it was, it has changed everything. I’m talking about the origin of the almighty Virus, of course. Our individual worlds are now tiny spaces in which the same activities repeat day after day, especially during the weeks of lockdown.

For some, it is getting the body battle-ready for COVID – drinking brews made from ginger, turmeric or pepper, squeezing lemon juice on everything that’s served, three different types of exercise regimens scheduled at intervals through the day . . .

For some, it is cleaning…

Some Indians have been asking the government “Why did you send vaccines meant for our children abroad?”

It’s common knowledge that when Serum Institute of India (SII) agreed to produce the millions of vaccines the world needed last year there were certain licensing agreements with AstraZeneca, UK.

One of them was the WTO’s stipulation that 84% (not sure of this number) of the manufactured vaccine was to go to the COVAX Facility for distribution to low- and middle-income countries, ninety-two of them.

1.1 billion vaccines were apparently manufactured last year on these terms. So the vaccines sent abroad were not the ones “meant for our children”.

The picture is different this year. India has millions of cases and needs millions of vaccines. So India has had to renege on the deal to supply vaccines to COVAX countries. For a while, the country did gamely try to live up to…

Going Negative, part 3

Let’s start with a joke:

A physicist, a biologist and a mathematician are sitting in a street café one morning watching an empty store on the other side of the street.They see someone unlock the store and go in.Time passes.Someone else goes in. More time passes. Then three people come out.

The physicist says, “Our measurements weren’t accurate.” The biologist says, “The two people who went in must have reproduced.” The mathematician says, “If one more person enters the store, it will be empty.”

Of course the joke here is that the mathematician is holding the absurd belief that there are a negative number of people in the store.1 The joke is built on our shared knowledge that although negative numbers make sense in some contexts, they aren’t sensible in the present context. But the knowledge that negative numbers do make sense in some contexts shouldn’t be taken for…
