wankers

You may not have noticed, but I’m in a foul mood for weeks now because of comments and reactions to the last line of the post on Finding Moonshine. I wrote

Du Sautoy is a softy! I’d throw such students out of the window…

and got everyone against me for this (first floor) defenestration threat…

That’s OK! I sometimes post what’s on my mind and if you don’t like it you are free to leave a comment, and, usually I won’t even bother to reply to it. But occasionally, stuff is bottling up un-healthily.

So, I thought it was a good idea to have a prolonged easter-vacation, somewhere in the south of France. The weather, food, rest, drinks, company and all that were just gorgeous

but …

A quick recap. Here’s the relevant section in duSautoy’s book again :

One of my graduate students has just left my office. He’s done some great work over the past three years and is starting to write up his doctorate, but he’s just confessed that he’s not sure that he wants to be a mathematician. I’m feeling quite sobered by this news. My graduate students are like my children. They are the future of the subject. Who’s going to read all the details of my papers if not my mathematical offspring? The subject feels so tribal that anyone who says they want out is almost a threat to everything the tribe stands for.
Anton has been working on a project very close to my current problem. There’s no denying that one can feel quite disillusioned by not finding a way into a problem. Last year one of my post-docs left for the City after attempting to scale this mountain with me. I’d already rescued him from being dragged off to the City once before. But after battling with our problem and seeing it become more and more complex, he felt that he wasn’t really cut out for it.
What is unsettling for me is that they both questioned the importance of what we are doing. They’ve asked that ‘What’s it all for?’ question, and think they’ve seen the Emperor without any clothes.
Anton has questioned whether the problems we are working on are really important. I’ve explained why I think these are fundamental questions about basic objects in nature, but I can see that he isn’t convinced. I feel I am having to defend my whole existence. I’ve arranged for him to join me at a conference in Israel later this month, and I hope that seeing the rest of the tribe enthused and excited about these problems will re-inspire him. It will also show him that people are interested in what he is dedicating his time to.

For starters, I’m getting old so I’m from those long-forgotten days when you had to do a Ph.D. to prove that you could conduct research independently.

A fortiori this meant that the topic of your thesis was your own choice and interest. The role of your Ph.D. advisor was to get you going and, occasionally, to warn you when you were straying too far afield but that was it.

You, and only you, were responsible to get the thesis finished and defended.

Today, the Ph.D. is just another item on the market to be consumed.

Graduate students shop around looking for the advisor having the best sales-pitch, offers the best deal and, if possibly, the best after-phd service aka the promise of an academic career.

Topic and main outline of the proofs are provided by the advisor and an exceptionally good student today means that (s)he proved a few results along the way on her/his own.

University policy and the promotion-rat-race appear to make the Ph.D. more important to the advisor than to the defendent.

Independence of research today means that after your PhD is obtained, you ditch your advisor and try to get into the slipstream of another more powerful guru, having better after-phd service prospects…

For those who stick with their old advisor, the moment of truth comes when they fail to get a renewal of their grant or a permanent position.

At that time one can hear complaints such as : “That persons’ student got ranked ahead of me and I always thought you were better than that person?” or “The better ranked people for the position are all doing that topic instead of ‘ours’, so I guess your topic isn’t so important after all!”. duSautoy’s captures it all in this one key sentence :

They’ve asked that ‘What’s it all for?’ question, and think they’ve seen the Emperor without any clothes.

As if, failing to get a permanent position is the advisors fault, more than yours…

Just for once, try to be honest to yourself : count the number of hours a day your brain-power gets you over 120 IQ. Substract from this the number of hours a day lost surfing the web idly, trying to read unreadable hep-th papers, socializing, kissing asses, socializing, doing fun things with you fellow graduate students, socializing, working on a relation, chatting, texing, emailing insults but softening it all with a closing smily 🙂 , socializing, etc… (you know the daily-drill of a 20-30-something phd-student a lot better than I do)

I’ll be damned if you get a positive outcome. But if you do, I’ll be happy to take you on as a PhD student…

Well, it’s no threat, it’s a promise : the first ex-student who gets me into a ‘why was it all good for?’ discussion will experience first floor defenestration! (provided I’ll get my window open in time)

And, to soften it all, I’ll add the obligatory 🙂

yahoo pipes on iTouch

The next thing on my tech-to-do-list : learn all about Yahoo Pipes :

Pipes is a powerful composition tool to aggregate, manipulate, and mashup content from around the web. Like Unix pipes, simple commands can be combined together to create output that meets your needs. Here are a few popular ways the service can be used:
– create your ultimate custom feed by combining many feeds into one, then sorting, filtering and translating them.
– geocode your favorite feeds and browse the items on an interactive map.
– remix your favorite data sources and use the Pipe to power a new application.
– build custom vertical search pages that are impossible with ordinary search engines.
– power widgets/badges on your web site.
– consume the output of any Pipe in RSS, JSON, KML, and other formats.

I’ve posted before on setting up your own lifestream, or your own planet, or scraping feeds, or subscribing to my brain, or … whatever. The good news is : all these ideas are now superseded by Pipes!

Pipes is a free online service that lets you remix popular feed types and create data mashups using a visual editor. You can use Pipes to run your own web projects, or publish and share your own web services without ever having to write a line of code. You make a Pipe by dragging pre-configured modules onto a canvas and wiring them together in the Pipes Editor. Once you’ve built a Pipe, you’ll be able save it on our server and then call it like you would any other feed. Pipes offers output in RSS 2.0, RSS 1.0 (RDF), JSON and Atom formats for maximum flexibility. You can also choose to publish your Pipe and share it with the world, allowing other users to clone it, add their own improvements, or use it as a subcomponent in their own creations.

This is the essential message to get : yahoo-pipes allows you to remix the web, filtering out all noise! And the good news is

  1. There are plenty of public pipes around to get you going, and
  2. Pipes has an iTouch-friendly interface (see above left). All you have to do is to Safari to iphone.pipes.yahoo.com and use them.

Here are a few public-pipes you can use out of the box!

  • iPhone / iPod Touch: The Most Comprehensive Feed Ever!, doing what it promises : giving you the best iTouch-posts without having to roam for them.
  • JSON Geocoder, returning lat/lon/address info from the the given address.
  • Uber Blog Search, Search all the blogosphere with one query. Hits Google, Ask, Technorati, and icerocket then returns the unique results. Below the web-interface giving the results for ‘noncommutative’…

and finally, one of my favorites, implementing to some extend the Lifestream-idea (iTouch-interface above left)

  • lifefeed – virable, Easily Aggregate your social whereabouts great for blogs profiles and more! Aggregates Your Feeds From: -Digg -Last.fm -Twitter -Flickr -Del.icio.us and your very own blog Adopt and Improve, enjoy!

I’ll promise to spend some time soon to set up my very own pipes and make them available…

The Newtonian
Legacy
is a free online book by Nick Evans. If you want a (somewhat
over-positively) review about it, head here. For me, it just didn’t work but then I’m
an avid consumer of thrillers and like to be surprised. I read though to
page 80 (of 138) which is pretty good as I usually lay down an
unreadable book much sooner (most are lend from the public library, so
I’d rather start a new one as soon as it becomes tiresome). But then I
wanted to ‘learn about the frontier of particle physics within a fast
paced crime adventure’. One exchange is pretty telling though (p.
40-41)

“Rule is don”t get involved in popularising
science.” “That”s a bit harsh. We have to tell people what we”re doing
if we want them to fund us,” said Carl. “Yeah, but it”s all lies. The
theories are all mathematics, yet we say all words. That”s why we get
these nut cases writing to us sometimes with “new theoriesiÃÇ. They”ve
just read a popular science book and mistaken it for the core of
science. They change some words and think they have a new theory. They
don”t understand that you have to get the numbers right for every
experiment you can think of. It”s just misleading.” “Well, OK,”conceded
Carl, “but you can make the point that you”re just reporting a
simplification and that if people want the real thing, they”d need
maths.”Everyone sought inspiration in their pints again.

So, that’s why it is impossible to write about mathematics for a
general public! Anyway, a bit frustrated I went to my favorite bookshops
and read a blurb which sounded all too familiar.

Oxford, 2006: a young woman is found brutally
murdered, her throat cut. Her heart has been removed and in its place
lies an apparently ancient gold coin. Twenty-four hours later, another
woman is found. The MO is identical, except that this time her brain has
been removed, and a silver coin lies glittering in the bowl of her
skull. The police are baffled but when police photographer, Philip
Bainbridge and his estranged lover, Laura Niven become involved, they
discover that these horrific, ritualistic murders are not confined to
the here and now. And a shocking story begins to emerge which
intertwines Sir Isaac Newton, one of seventeenth-century England’s most
powerful figures, with a deadly conspiracy which echoes down the years
to the present day, as lethal now as it was then. Before long those
closest to Laura are in danger, and she finds herself the one person who
can rewrite history; the only person who can stop the killer from
striking again…

The first half of the
book
is rather promising (and at least its well written).
Mathematics even makes a short appearance as daugther Jo is studying
maths. Not that she contributes much of her talent to the story (apart
from contributing to solving one riddle) and in the end it seems to be
much more important to date the right boyfriend than to do math! The
book really becomes laughable when the couple is trapped in a maze 100
feat below the Bodleian library. Pure Indiana Jones-remake : expecting
pitfalls? here they come! what else do we remember of the movie?
arrow-traps! sure enough they appear. Oh, this must be that movie, so
whats next? well, sure enough (p. 343 “A massive block of stone crashed
down from the lintel of the archway, landing squarely with a thump on
the dusty floor. They were sealed in.” Presumably the authors
inspiration dried out!

Mind you, I do not want to be negative on
principle. Sometimes (too rare) I do read an enjoyable, interesting,
intelligent thriller. The last one Ive read was

Brother Grimm by Craig Russell is a must read if you are into
serial-killer stories. Heres the synopsis

A girl’s
body lies, posed, on the pale sand of a Hamburg beach, a message
concealed in her hand. ‘I have been underground, and now it is
time for me to return home…’ Jan Fabel, of the Hamburg murder
squad, struggles to interpret the twisted imagery of a dark and brutal
mind. Four days later, a man and a woman are found deep in woodland,
their throats slashed deep and wide, the names ‘Hansel’ and
‘Gretel’, in the same, tiny, obsessively neat writing, rolled
tight and pressed into their hands. As it becomes clear that each new
crime is a grisly reference to folk stories collected almost two hundred
years ago by the Brothers Grimm, the hunt is on for a serial killer who
is exploring our darkest, most fundamental fears – a predator who kills
and then disappears into the shadows. He is a monster we all learned to
fear in childhood.

An original point of view, an
unorthodox setting (Hamburg!), interesting and real life personages what
more do you want? Oh, you want to learn something from reading a
bestseller? To me, this book was an eye-opener. Ever wondered why all
these serial-killer-books become bestsellers? Here’s the answer (p.
227)

<

p>”Weiss toke a novel from the bookshell before him!! ‘Today
we continuously reinvent these tales. The same stories, new characters.
This is a bestseller – a story about the hunt for a serial killer who
ritually dismembers his victims. These are our fairy tales
today. These are our fables, our Maerchen. Instead of elves and kobolts
and hungry wolves lurking in the dark corners of the woods, we have
cannibals and dissectors and abductors lurking in the dark corners of
our cities.
It is in our nature to guise our evil as something
extraordinary or something different: books and films about aliens,
sharks, vampires, ghosts, witches. The fact of the matter is that there
is one beast that is more dangerous, more predatory, tan any other in
the history of nature. Us.”
