Weight in dollars squared
PROGRAMMERS at a Famous Web Search Engine are forever trying to find new ways to be helpful ā and to keep us coming back. Clive Jones was recently looking up exchange rates between the British pound and the US dollar. He discovered that if you put a figure and a currency in the search box, the search engine makes āa decent stab at providing an instant conversion without the need to select a website and search aroundā.
Later, he accidentally typed āpound pound dollar rateā into the search field and received the result: ā1 British pound pound U.S. dollar = 0.677349486 kg U.S. Dollars2ā. After studying this, Clive says he ācan only conclude that they have attempted to provide the weight of a pound of dollarsā. What the intriguing unit the kilogram-dollar-squared might represent continues to elude him, though, as it does us.

Ignoring Cliveās warning that we were in danger of opening the floodgates of permutation, we tried āeuro euro dollar rateā, which wasnāt recognised as a currency conversion; then āeuro pound dollar rateā, which we were informed was ā1 Euro pound U.S. dollar = 0.584544487 kg U.S. Dollars2ā.
Something similar happens for yen. Disappointingly, āblue whale pound dollar rateā gives the usual selection of links, many to pages that do not mention whales. One links to the news, attributed to Fox, that ā Would Equal Weight Of 89 Blue Whalesā ā taking us into the outer reaches of fiscal strangeness.
Brian Robinson sends us a photo of a large sign outside a showroom in what he describes as ārural Virginiaā. It says: āAntique tables made dailyā
Lift is four floors short
OUR āmissing floors in buildingsā theme has inspired readers to send us stories about buildings around the world equipped with lifts that miss out certain floors (4 May). Now Alan Chattaway sends us the strangest one yet.
āHere in Vancouver, Canada, one of our tallest buildings has four missing floors,ā he says. āThe is so narrow that it would have swayed in high winds or earthquakes. To prevent this, 400 tonnes of water are on the roof to increase inertia, and four floors below are filled with concrete cross-bracing.ā
Alan concludes that āthe missing floors may not be obvious to those using the elevatorsā. We think this is just as well. The knowledge of all that water and concrete just above your head when you reach the ātop floorā would not be reassuring.
Theoretical types of people
INEVITABLY, Feedback readers have sent in further responses to our mentions of the T-shirt slogan that there are āonly 10 types of people in the world: those who understand binary and those who donātā (16 March and 11 May). John Hartley suggests an alternative: āThere are {{},{{}}} types of people in the world ā those who understand the construction of ordinal numbers in axiomatic set theory, and those who donāt.ā
Feedbackās resident mathematics guru agrees. The symbol ā{}ā, he explains, represents the empty set, which has no members; and {{}} represents the set whose single member is the empty set ā which is how we get to āoneā in set theory. And so on to ātwoā, and the rest of arithmetic.
All of which may well be true. However, Feedback suspects that the market for this T-shirt will be somewhat smaller than that for the binary variant.
One dimensional volume
AS HE was about to send a parcel via , Tim Walker decided to check first that it wasnāt too big or heavy, so he clicked on the link to ācheck parcel sizeā. Here he was presented with the statement: āmax volume up to 225cm.ā
He had a bit of a struggle with āmax volume up toā, wondering how it was possible to have more than one maximum, but decided to treat this as mere tautology. But this still left him with a one-dimensional volume, leading him briefly to wonder how many one-dimensional parcels you can fit in a three-dimensional delivery van.
He assumed, of course, that they had omitted ācubedā after ācmā. Then he noticed that the website includes a handy āUK volume calculatorā, so he decided to check if its definition matched the one he knew. He put in ā10 cmā for parcel length, parcel width and parcel height, hit ācalculate sizeā and was given a ācombined sizeā of ā50cmā.
Tasty bin bags
A SIGN in Roger Calvertās local ASDA supermarket proclaims āTried, Tasted and Chosen by Youā. The two displays it refers to, Roger tells us, are for liquid laundry detergent and plastic bin bags.
Take it all with you
FINALLY, Feedback frequently does a double take when a disembodied voice on Londonās Underground admonishes passengers to ātake all your belongings with youā when leaving the train. Would they really appreciate us wedging the doors open while we unloaded 1000 books, the cast-iron cookware and the shelves they sit on?
