How massive is a cubic metre of water?

Massive SIgh

How massive is a cubic metre of water? The reply, which comes as a part of our persistent sequence on Uncommon Various Measurement Items, is that it’s location dependent.

An ABC Information merchandise concerning the East Australian present courtesy of Kevin Ritchie notes that it “can carry 40 million cubic metres of water every second – the equal of 300 billion pints of beer”.

In the meantime, the world’s greatest synthetic water-filled gap, at present being in-built Cornwall, UK, to simulate excessive environments, is claimed, in a press launch forwarded to us by Laurel Stanford, to carry “over 42,000 cubic metres of water – the equal of 17 Olympic measurement swimming swimming pools or 168 million cups of tea”.

Our most important concern is with the maths. To current an Australian with a pint of beer that comprises simply 0.13 litres isn’t a technique to make a pal for all times. A 0.25-litre cup of tea appears extra affordable, though we desire consuming our tea in pints, and never these of the Australian selection.

As we furrow our forehead over all this, Roger Lampert writes in to question whether or not, once we quoted the Mona Lisa’s measurement as 21 by 30 inches (29 Might), we meant trendy English inches or the pre-revolutionary pouce, equal to 1.0657 of the Rosbif selection. Roger, everybody: it was precisely this form of nonsense that led to Louis XVI’s demise.

Unknown cyberwarrior

Hungary At present studies that the primary statue of bitcoin creator Satoshi Nakamoto is to be erected in Budapest, celebrating, in response to the mission’s initiator András Györfi, the creation of “an environment friendly, honest, and clear database that eliminates mistrust between folks and may make the world a greater place in lots of areas, from meals provide to help supply”.

The truth that nobody is aware of who Satoshi really is, or whether or not certainly they’re one particular person, isn’t thought to be a deal-breaker for the statue, which can include a hooded determine with a reflective face to bolster the concept “we’re all Satoshi”.

Nicely, Suggestions isn’t, for one: maybe we will clear up this thriller by elimination. In the meantime, the article doesn’t state what the sculptors are being paid in.

What vaccines can’t do

These pesky fact-checkers destroy one other nice story, as Full Truth runs an merchandise entitled “Getting a Covid-19 vaccine doesn’t imply you possibly can hook up with Bluetooth”.

This responds to a spate of studies on Fb that the jab makes you magnetic on the injection web site. This might have been enjoyable, relying on the power of the magnetism. Ah nicely.

In the meantime, we’ve got a “pal” who swears that since that they had their jab their telephone can get 5G for the primary time…

Breaking the mould

Richard VandeWetering writes from one other London in Ontario, Canada, apparently in response to our merchandise on a single pixel being bought for $1.36 million of cryptocurrency (1 Might), with information of artwork that’s breaking down boundaries.

The Jon Sasaki: Homage exhibition, which will be seen, nearly within the first occasion, on the McMichael Canadian Artwork Assortment simply exterior Toronto, “is a collection of images depicting petri dishes with bloomed bacterial cultures derived from swabs of the palettes and brushes utilized by members of the Group of Seven and Tom Thomson”.

Is that this artwork? We’ll take a punt on “sure”, but when so it’s undoubtedly cultural appropriation.

Artwork warning

In the meantime, John MacCullum studies some very non-fungible artwork on a roundabout in Walsh Bay, Sydney, the place a big, shiny purple automotive has apparently been crushed by a huge granite boulder.

This visceral sight is accompanied by roadworks-like indicators on coming into and exiting the roundabout: “Paintings forward” and “Finish paintings”. Now that undoubtedly is artwork.

A Politzer writes

An e mail of grievance reaches our inbox from Nobel-prizewinning particle theorist H. David Politzer (“one among many, however the one one with an H.”, in his phrases).

The invention of his papers on the physics of the banjo led us to invest not too long ago on his a number of identities (24 April). It’s not a lot this that David objects to, as the actual fact we obtained the weblink to his banjo work improper. “Because the report reveals, I’m fairly enthusiastic concerning the banjo stuff and comfortable for it to get publicity – good or in any other case,” he writes in a follow-up e mail.

There’s additionally extra connection between the 2 elements of his printed oeuvre than you may assume, he factors out. The identical methods that allowed him to make the primary half-way correct estimate of the unexpectedly lengthy lifetime of the J/Psi particle within the Seventies additionally allowed him to mannequin from first ideas the banjo’s uncommon and distinctive resonance traits.

“I may proceed with how banjo physics concept requires logarithmically divergent renormalization. That story makes contact with why cleaning soap bubbles and balloons burst when pricked with a pin. However I’ve gone on greater than lengthy sufficient,” he ends. By no means, David, thanks for writing. And that hyperlink: www.its.caltech.edu/~politzer.
