Reinventing maths

HOLD the front page! Richard Taylor alerts us to a by an American physics student in England last year at about a 1994 paper by M. M. Tai entitled: “A mathematical model for the determination of total area under glucose tolerance and other metabolic curves” ().

Just what is it about Tai’s finding that has made it worth a mention after all this time? As Flip Tomato suggests, let’s substitute a variable in the title: “A mathematical model for the determination of total area under x curves”. Now, anyone who persisted with mathematics into their late teens may recognise that Tai has reinvented integration. That would be the mathematics of finding areas under curves, as originally devised by Isaac Newton and/or Gottfried Leibnitz – in the 1670s.

To be fair to Diabetes Care’s readers, some of those commenting on the article noted this. Even so, Flip Tomato found 75 papers citing what Tai calls “the Tai method”, and when Feedback looked there appeared be .

That so many still cite a paper that “discovers” something mathematicians have known for three centuries makes the case, as Flip Tomato notes, for “the importance of interdisciplinary communication”.

Drunken dogs

MEGAN, a border collie belonging to a colleague of Gerald Legge, was recently taken to the local vet because she was suffering from skin irritation, Legge tells us. To help calm her agitated response to the condition, the vet prescribed some Tavegil antihistamine tablets. The medicine came with the instructions: “Take two tablets as a single dose. Give in the evening. FOR ANIMAL USE ONLY. May cause drowsiness: if so do not operate machinery or drive. Avoid alcohol.”

The Nubble constant

READER Joe Hardman was browsing Nature‘s website when he stumbled across an abstract for a paper called “The Nubble constant and Virgo cluster distance from observations of Cepheid variables” by Michael Pierce and colleagues.

“Please tell me this is some real constant and not a horrendous blooper,” Hardman begged Feedback. Concerned that the ghost of Edwin Hubble might not take too kindly to his constant being usurped by Dr Nubble, we decided to investigate. Typing “Nubble” into the search box at revealed things to be far worse for the American astronomer than we thought. Nature listed more than 20 articles about the Nubble constant, as well as Nubble diagrams and references to the Nubble Space Telescope.

In the journal’s defence, it must be said that the typo only appears online; Hubble’s name is shown correctly in the printed magazine. An insider tells us that gremlins crept into the optical character recognition software used to scan in abstracts from old Nature papers.

Nature has now corrected the errors.They had to do it, of course, but we’re left with a slight pang of sorrow. We had developed rather a soft spot for the Nubble Space Telescope.

Tracking after the event

AFTER he had ordered some goods online, Derek Woodruffe was offered a link to the UK Post Office’s “track and trace” service. He is not always in his office, so he thought it would be helpful to be told roughly when the parcel would be delivered there. He duly typed his 13-digit reference number into the Post Office website , whereupon he got this answer: “‘Recorded Signed For’ items are only tracked after the item has been delivered. Depending on whether the item was sent first or second class, this may be a few days after posting. Please try again later.”

Woodruffe is puzzled about the usefulness of this. He assumes that after the item has been delivered he will know where it is and won’t need to have it tracked. On the other hand, it occurs to him that if he subsequently loses it he will be able to contact the Post Office to locate it for him.

Car park holiday

ON HIS return from a four-day holiday abroad, Phil Keeling received this emailed request from his travel agent: “Welcome home! Dear Mr Keeling, we hope you enjoyed your trip and stay at Liverpool On Airport Parking. We would really appreciate it if you could take 2 minutes to rate Holiday Extras so we can improve our service and in return we’ll enter you into a draw to win a London Shortbreak for 2!”

Keeling was tempted to fill in the form. Who knows the joy of a couple of nights’ stay in the car park at London Heathrow airport?

Running out of downloads

FINALLY, in the email Jacqueline Teng received from Seagate offering holiday specials, there was the offer: “Free tunes! Download a free mp3 – holiday goodness from us to you. Don’t delay, downloads are available only while supplies last!” Teng is curious to know just what it is that limits the supply of downloads.
