The Indian state of Rajasthan produces more solar than any other. It has rejected a 3.2 GW coal power plant, because the bids to build it were more expensive than bundling renewables with batteries.

Have you ever wondered why physicists are so excited to study the Higgs Boson at a new Higgs Factory collider?
Wonder no more!
I explain what a Higgs factory is, why we need one, and the amazing measurements the machine will make.

The use of the Notwithstanding Clause is out of control. It’s up to voters to stop it
The architects of Canada's Charter of Rights and Freedoms thought the Notwithstanding Clause would only be used in exceptional circumstances. Conservative premiers seem determined to prove them wrong.

In a theory called quadratic gravity, “ghost” particles violate physicists’ intuition of quantum fields. This made the theory unpopular for decades. Now, it’s experiencing a resurgence.

Was reading Maureen Jenning's 'Heat Wave', set in 1930s Toronto.
A character in the book didn't want a horse to be whipped. She feared if the horse died, it could be "sent to the glue factory." The phrase became a common, albeit grim, idiom for an old or unwanted horse being sent to slaughter.
