One Former Physicist’s Thoughts on the Large Hadron Collider (or Will the World End?)

I have a college buddy from Duke – David Hardtke, who is retired physicist who worked at LBNL and CERN (the guys who built LHC) and now Chief Scientist at SurfCanyon a search startup, who sent us his thoughts on what’s going to happen with the Large Hadron Collider (LHC) as its now online (though not yet attempting the things the world is worried about).  As a geek at heart – I am fascinated by stuff like this.

So when asked whether the LHC would create black holes that would destroy the world – here’s what Dave said:

Today the $10 billion dollar Large Hadron Collider at CERN in Geneva
Switzerland took its first baby step towards operation.  The LHC is the
highest energy particle accelerator ever built.  I will now make
predictions about the outcome of these experiments — unlike other
predictions on this list I allegedly know what I am talking about on
this subject.

1)  The main goal of the LHC is to find the last piece of the so-called
standard model.  The standard model is a theory that encompasses all
known particles and their interactions.  There are two types of
particles: leptons (including electrons, neutrinos, and their cousins)
and fermions (quarks) that interact via gauge bosons (photons, gluons,
and the W and Z).  The missing piece is something called the Higgs which
is supposed to give all of these other particles their mass (without the
Higgs, they are all massless).

PREDICTION:  Higgs is found, probably around 2010-2011.  Peter Higgs
dies one month before discovery and is thus denied Nobel Prize.

2)  Most physicists think there is a whole zoo of fundamental particles
more massive than any we have observed.  The reason they speculate of
the existence of these particles is that the standard model is ugly –
it has a bunch of “free” parameters that are arbitrarily tuned to crazy
values (you can reconcile God and physics by positing that only a God
could fine tune such a mess).  The favorite new theory is super-symmetry
which speculates that particles we have observed have a corresponding
superpartner such that there is a super-lepton for each fermion and a
super-fermion for each lepton.

PREDICTION:  Supersymmetry (and all related theories including string
theory) are B.S. (I am in the minority of physicists on this point, but
my paycheck no longer requires that I believe it).

3)  Some predict that LHC will create mini-black holes that may eat up
the earth.  This is definitely not going to happen since it requires
string theory to be true and string theory is BS (see previous
prediction).

PREDICTION: Earth survives

4)  96% of of the gravitational mass of the universe is unaccounted for.
There is something called dark matter that accounts for about 20%.  Many
predict that the LHC will find the Dark Matter.  This requires
super-symmetry or something similar to be true.

PREDICTION:  No dark matter found at LHC.

5)  The LHC is supposed to be a discovery machine that opens up a whole
new zoo of particles.  The next accelerator (the International Linear
Collider) will cost $40 billion and is designed to clean up the mess.

PREDICTION:  LHC is last large atom smasher ever built.

REQUIRED BEER COMMENT:  If you’re ever in Geneva, the CERN cafeteria
serves the cheapest beer in all of Switzerland.

UPDATE: Slight edits to Dave’s background

The Fallacy & Conundrum of User Influenced Ad Models

As the online display ad business continues to focus more and more on the idea of user targeting (the idea of targeting the user instead of targeting the site or the context of the page), there is a growing interest and some potential concern around how we’re going to target users.  With some of the more extreme ad models now scaring the bejeebus out of users (see Phorm and Nebuads) and growing concerns about the hegemony of companies like Google and the data it’s collecting about users (see the lack of privacy built into Google’s new browser), some companies are going creating ad networks and systems based on the ideas of users themselves giving explicit feedback about ads they like and don’t like.  Let’s just say I think that any ad model that relies on users giving feedback is a disaster and doomed from the start.

Filed Under – Doomed to Epic Fail

On paper, the idea of allowing users to give direct affirmative consent and feedback about ads they like, things they want, their interests sounds very democratic and utopian.  Power to the People! and all that.  The problem is that any model that relies on users doing anything other then what they really want to do flies in the face of what people actually do online.   Despite the web being about interaction and participation, almost 99% of what people do online is read, not participate.  At any UGC website – only a small portion of the audience actually ever uploads anything.  At YouTube for instance, I’ve heard reports that despite the 100 million users it sees everymonth less then 600,000 users ever upload and share anything publicly.  600,000 might sound like a lot but it’s less then 1% of their user base.  At FoggyGames.com, the casual games website I own, the percent of users who’ve ever rated a game – which only requires a nano second of effort to click on the classic rating star – is less then 1% as well.  Again and again you see participation rates in that range.  So now these new ad models expect the vast majority of users to actually rate each and every ad – even when they have shown again and again they won’t even participate in sites and actions where they actually want to participate – I don’t think so.

Sampling Don’t Work

OK then what about the idea that you don’t need every user to participate that just getting that sample to tell you about what ads they like or don’t like.  Unfortunately the idea of a sample defeats the whole principle of user targeting.  The basis of user targeting is targeting a specific’s user definite demographics, intents or interests.  And again and again – we’ve seen that sampling doesn’t work since it is the way that most site level targeting works today.  Sites sell ads based on samples of their user base – their user base is 60/40 Female/Male and thus they sell a disportionate number of ads targeting females (it’s largely what Glam Media does across multiple websites – not very sophisticated technically speaking).  Thus lots and lots of men get poorly targeted ads just because they go certains websites in this example.  The whole idea of user targeting is to solve that problem – show ads to men with ads for men in that scenario instead of generic ads based on a sample.  So without finite, user level data no user targeting scheme can work.  So in a web where you’ll likely get more then 1% of users to participate, models that requires something much greater then 10% and more like 25% of users to participate seems like a folly even at the start.

Conundrums and Contradictions

The conundrum and contradiction with user targeting is that users say they don’t like being tracked.  Yet what they won’t do is explicitly tell the advertiser or advertising provider what they want.  And yet, again and again users say they want ads targeting to them individually as way to increase the quality and relevancy of ads.  I’ve done enough research to know users like relevant ads – they actually stop them ads and start calling them information (ads are pejorative term meaning noisy, irrelevant, uninteresing, annoying marketing messages).  Tying a user’s information and interests from where users express them willingly (communities, social networks, etc.) to where they get exposed to ads is a way to solve that.  Doing so in a conscientious and respectful manner is critical for all players in the market (trust me I speak from experience – one bad actor can sink a market) if we want to solve the user targeting and participation problem.  And the folly is we’ll be able to avoid that get by getting the all the users online to vote on each and every ad – I’ll hopefully save everyone some time and investors money ‘cuz it ain’t going to work.
