Feedback is our weekly column of bizarre stories, implausible advertising claims, confusing instructions and more
A song for a satellite gone
PLUCKY little Philae鈥檚 epic and lonely struggle against the absence of gravity ensures that at least some of us are gripped by its stalled quest (6 December 2014). Will it wake? The most hopeful estimates are that now is the time to listen (see 鈥�Asteroid ahoy!鈥�).
Feedback will not join what one journalist colleague called 鈥渢he idle speculation鈥�. Instead we turn, not for the first time, to the words of John Lennon: 鈥淧lease, don鈥檛 spoil my day, I鈥檓 miles away / And after all I鈥檓 only sleeping.鈥� Now we know why these lyrics on the album Revolver.

New dimensions in burglary
CLOSER to Earth 鈥� indeed, several metres beneath it 鈥� we have the raid on the Hatton Garden Safe Deposit Company in London, which netted a quantity of valuables that is undisclosed, not least to the tax authorities. The BBC captioned a photo thus: 鈥淭he image shows the hole made using a heavy-duty drill, a Hilti DD350. It measured 50cm (1.64ft) deep, 25cm (0.8ft) high, 45cm (1.5ft) wide and 89cm (2.9ft) tall.鈥� Within minutes four readers had written in. Arthur Chance鈥檚 representative query was: 鈥淭he only question is, if they can make 4D holes, how come they didn鈥檛 just step round the wall?鈥� We refer readers to any good book on multidimensional topology for explanation.
The BBC naturally retro-proofread its caption smartish. Paul Cooper, however, found that had the rather more interesting version.
More numerology of cosmology
MOVING away from Earth again, probably, we have further thoughts to report on the numerological or other significance of 187.5. This number seems mysteriously to recur in measures of the frequency dispersion of fast radio bursts (18 April).
Richard Chapman responds to Chris Conklin鈥檚 observation that 1.875 is the smallest positive solution of the equation cos(x)cosh(x) = 鈥�1 by suggesting investigation of a 10-dimensional analogue of this formula, which we shall not write out. 鈥淚t could shed some light on a possible metric amongst the 10 dimensions of string space,鈥� he proposes.
Fiona Vincent suggests that, contrary to our first assumption that 187.5 is a pure number, it has units: centimetres-3 parsecs, which she describes as 鈥渢he sort of convoluted unit that astronomers love鈥�. Had they chosen to express it instead in, say, inches-3 light-years, Fiona says, 鈥渢he common factor would have been 10,020鈥�. We鈥檙e looking into that.
Falling for the metaphor peril
SEARCHING for references to 187.5 in our comprehensive piling system led it to throw up instead a thought about the challenge of presenting numerically based news. Consider the plight of Geraldine Bedell, founding editor of , a website for grandparents, asked to comment on a policy proposal floated in 2012 by George Osborne, then chancellor of the UK鈥檚 exchequer. This boiled down to replacing the policy 鈥渋f you are a pensioner, then you are entitled to a winter fuel allowance鈥� with鈥� well, with an arithmetically complicated set of means-testing calculations to decide eligibility.
Geraldine : 鈥淲e know that whenever you have means testing you get a cliff edge鈥�, which is a reasonable summary of the arithmetic effect. 鈥淎nd very often the wrong people fall off the cliff,鈥� she went on. So which grannies would fall off?
A new source of randomness
INATTENTION has led us to discover an accidental random-text generator. We went to an online translation engine and started typing English into the 鈥渟ource鈥� field on the left 鈥� not noticing that it was expecting Arabic. Typing 鈥淭his is not Arabic鈥� produced a string of Arabic text on the left and 鈥淭his Is Whoosh Net wears鈥� on the right-hand side.
This doesn鈥檛 seem to work in Hebrew 鈥� although typing in 鈥淭his is not Hebrew鈥� produces 鈥淭his is not English鈥�, which suggests someone somewhere has been thinking about how it might work if it did. In Russian we start to get a direct transliteration of 鈥淭his is not Russian鈥�, which is amended as we type, in the style of 鈥渄id you mean鈥︹�� suggestions, then translated as 鈥淭his IP chickpeas Rusin鈥�. Probably, there鈥檚 a use for this鈥� maybe.
Demo in doctrinal dispute
THE latest missive from oh-so-caring Christian Concern arrives: 鈥淒emo at hustings to protestanti-free speech Diane Abbott鈥�. The Freudian typo blunts the group鈥檚 objection to the MP鈥檚 objection to pickets outside abortion clinics鈥�
The naming of small things
FINALLY, another email caused us a double-take: its coming from the address info@rna.org made us expect something biomedical. Instead we read: 鈥淪tudents: submit religion news stories for $600 award.鈥�
It seems is the site of the Religion Newswriters Association, and has been since 1997. Three-letter domains are quite the thing on the web these days: but the Religion Newswriters got to before, for example, .
They are not the only obscure virtual claim-staker. We note that is owned not by the famed research labs, but, since 7 August 1995, by Bell Laboratories Inc. of Madison, Wisconsin, which bills itself as 鈥渢he world leader in rodent control technology鈥�. The more famous labs registered on 10 January 1996. We wonder how many other organisations that should have known better wound up stuck with second-choice domain names.
