Correlation isn’t causation — the EVM edition

The space to disagree with the Election Commission’s position vis-à-vis the integrity of electronic voting machines without finding oneself backtracking into the Congress or the BJP camps is shrinking, and both national parties as well as the Supreme Court have been wilfully engendering this state of affairs at the expense of — ironically — logic. …

Review: ‘Vettaiyan’ (2024)

Watch it, but fast-forward through some parts. Vettaiyan steers clear of unconditionally qualifying “encounter killings” as the only way out — a line many Tamil films have been only too happy to tout of late. There’s in fact an instructive passage at the film’s start that’s probably deliberate. Rajinikanth’s character says there is no personal …

I realise Shashi Tharoor is frustrated here — revealing the increasingly evident gap between what the Delhi and the Indian governments can do about air pollution and the scale of …

From 'Tamil Nadu heatwave policy is only a start', The Hindu, November 21, 2024: Estimates of a heatwave’s deadliness are typically based on the extent to which the ambient temperature deviates from the historical average at a specific location and the number of lives lost during and because of the heatwave. This is a tricky, …

An infuriating editorial in Science

I’m not just disappointed with an editorial published by the journal Science on November 14, I’m angry. Irrespective of whether the Republican Party in the US has shifted more or less rightward on specific issues, it has certainly shifted towards falsehoods on many of them. Party leaders, including Donald Trump, have been using everything from …
