NASA satellite fall on Earth: 1-in-3200 chance to hit someone. How so?

How was this statistic computed? Is it based on the formula

Q = 1 - (1 - x/y)^26 = 1/3200,


  • If we pack all 6 billion human beings into a very compact square area, that area will cover x square miles.
  • The total area of the earth is y square miles,
  • Q is the chance that at least one out of 26 pieces (expected to fall on earth) hits the square area in question

If this is the case, then the human beings occupy a proportion R = 1 - {1…

Lifetime value of an e-mail blast: much longer than you think

See below an example of an Analyticbridge email campaign that was monitored over a period of about 600 days. It clearly shows that 20% of all clicks originate after day #5. Yet most advertisers and publishers ignore clicks occurring after day #3. Not only 20% of all clicks occurred after day #3, but the best clicks (in terms of conversions) occurred several weeks after the email…

Firm sends bots into chats to solicit stolen data | San Francisco Chronicle

Hackers have proved they can crack just about any computer network, from Sony's to Citigroup's. Afterward, they face another challenge: unloading the virtual booty.

They often take stolen credit card numbers, online banking credentials, e-mail logins, and Social Security numbers to a sprawling network of underground chat rooms and invitation-only forums, where such data are bought and sold. Law enforcement investigators hoping to catch the crooks lurk there as well, but with hacking…

Scientists tried on manslaughter charges for providing incorrect predictions | USA Today

ROME (AP) – Seven scientists and other experts have gone on trial on manslaughter charges for allegedly failing to sufficiently warn residents before a devastating 2009 earthquake that killed more than 300 people in central Italy.

The case is being closely watched by seismologists around the globe who insist it's impossible to predict earthquakes and dangerous to suggest otherwise, since seismologists will be discouraged from issuing any advice at all if they fear…

Question from an amateur to analytics professionals

I am a Ph.D in chemistry and specialist in validated bioanalytical methods and also an amateur in database analytics.

I accidentally developed a very strange theory concerning living systems.

For me there are Physical Living Organisms (PLO) (like microorganisms, plants and animals) with a genome located in their body …..and a project for life (see Prof. Jacques Monod).

On the other side there are Non Physical Living Organisms (NPLO) and because of their “living” nature…
