It is a public holiday and father’s day here in Germany, so I get to relax a bit. At Sapphire I made an off hand comment about executive dress sense, and someone said write a post about it. So I will.
Scott Schuman’s the Sartorialist is one of my favourite blogs and, in the words of the Kinks, I am a dedicated follower of fashion. Well sort of. I do like a good suit and tie. I’m a regular reader of the English cut blog too.
I’m not a mathematician, but one of the joys of working at SAP is that I get to meet some really interesting mathematicians and physicists. Loren, for instance, who has a great food blog, explained basic stats to me with the patience of Job.
There is a fascinating book that anyone interested in ties or maths should buy. (I’m not sure who has my copy, so please drop it back) Two theoretical physicists, Fink and Mao wrote the 85 ways to tie a tie. The Mathematics of knots is, apparently, a significant field of study. They comment on the site.
Recently in the magazine Nature, we proposed a mathematical model to calculate and classify all possible tie knots. Of the 85 found, we duly predicted the four knots in widespread use and further introduced nine new aesthetic ones.
The maths is a little beyond me, but it is fun trying some of the different knots out.
Photos from the sapphire07 flickr photo stream. Thanks mainly to David and Charlie. Herewith sartorial SAP. (corrections to my descriptions welcome from any fashionistas out there)
Henning Kagermann wearing a mid spread collar with snap tabs, single cuffs white shirt, and a pink woven tie. Knotted with a Windsor.
Here is Kagermann at Sapphire Atlanta. consistent look, different tie.
Ernie Gunst: Head of SAP EMEA
Similar look. Strong pink tie, Windsor or half Windsor knot. mid spread collar. In my opinion the trousers are probably a touch long, although this look is quite fashionable at the moment.
The pink tie theme has reached the SME market. Tom Kindermans, SVP SME EMEA. Midspread collar, perfectly tied Windsor (I think) . Suit probably Hugo Boss.
Leo breaks the pink tie trend with an elegant dark blue patterned tie. Grey suit with faint pale blue chalk stripe, single cuff shirt. Immaculate!
Chris Conde, CEO of Sungard. In a bow tie. Excellent! I saw it close up later, and it is a blue and red checked pattern. Definitely not a clip on. (I asked him!)
For his keynote Leo wore a blue suit with a blue tie. The tie had small polka dots on. Single cuff white shirt, mid-spread and a half- Windsor knot.
Hasso Plattner at Atlanta. For years Hasso has often worn a very widespread, cutback collar, and he tends to tie a big Windsor knot. Here in chalk stripe double breasted suit.
Hans-Peter Klaey, mid spread collar, quite long points, probably an eterna shirt. I think this is his favourite tie, as he wears it alot.
Amit Chatterjee, head of GRC,with button down collar, Lucian check, single cuff. 4 in hand knot. This is a very American look, but the tie is probably an Armani or similar.
Ian Kimbell’s tie, on the other hand, is rather off the wall. Much like Ian.
To quote my favourite novelist of all time.
“What do ties matter, Jeeves, at a time like this? … “There is no time, sir, at which ties do not matter” — PG Wodehouse, Jeeves and the Impending Doom
Perhaps I will start a photo blog of developer attire next.
