The Giants Causeway of Ireland

The Giant’s Causeway in Ireland never fails to impress anyone. It is a magnificent and magical site which may be one of the best in the world. Mind boggling rock formations and inaccessible bays which have influenced how plants, animals, and locals have survived through the ages.

Prime numbers

Several students were asked the following problem: Prove that all odd integers higher than 2 are prime.

mathematician: 3 is prime, 5 is prime, 7 is prime, and by induction, we have
that all the odd integers are prime."

Physicist: 3 is prime, 5 is prime, 7 is prime, 9 is ... uh, 9 is an
experimental error, 11 is prime, 13 is prime... Well, it seems that
you're right."

Wouldn't a modern physicist employ something like renormalization?
3 is prime, 5 is prime, 7 is prime, 9 is ...
9/3 is prime
11 is prime, 13 is prime, 15 is ...
15/3 is prime
17 is prime, 19 is prime, 21 is ...
21/3 is prime

Quantum Physicist: All numbers are equally prime and non-prime until observed.

Chemist: "3 is prime, 5 is prime, 7 is prime.. that's enough."

Cosmologist: 3 is prime, yes it is true....

Engineer: 3 is prime, 5 is prime, 7 is prime, 9 is ..., 9 is
..., well if you approximate, 9 is prime, 11 is prime, 13 is prime...
Well, it does seem right."

Engineer: 3 is prime, 5 is prime, 7 is prime, 9 is not working, fetch
toolbox.

Engineer: 3 is prime, 5 is prime, 7 is prime, 9 is prime, 11 is prime...

Computer scientist: I've just whipped up a program to REALLY go and prove
it..." He goes over to his terminal and runs his program. Reading
the output on the screen he says, "1 is prime, 1 is prime, 1 is prime,
1 is prime...."

Computer scientist using Unix: 3's a prime, 5's a prime, 7's a prime,

Computer Scientist: 3 is prime, 5 is prime, 7 is prime, 7 is prime,
7 is prime, 7 is prime... Bus error. Core dumped.

The computer programmer method is:
"3 is prime, 5 is prime, 7 is prime, 9 is prime, 9 is prime, 9 is prime,
9 is ..."
Opps, let's try that again:
"3 is prime, 5 is prime, 7 is prime, 9 is ... 3 is prime, 5 is prime,
7 is prime, 9 is ... 3 is ..."
Um, right. Okay, how about this:
"3 is not prime, 5 is not prime, 7 is not prime, 9 is not prime..."
So much for the beta releases. Ship this:
"3 is prime, 5 is prime, 7 is prime, 9 is a feature, 11 is prime..."
and put on the cover "More prime numbers thanb anyone else in the
industry!"

Coming soon:
"3 is a prime, 4 is a feature, 5 is a prime, 6 is a feature, 7 is a prime,
8 is not yet implemented, 9 is our backwards compatibilty module, ..."

Windows programmer: 1 is prime. Wait.

Mac programmer: Now why would anyone want to know about that? That's not
user friendly. You don't worry about it, we'll take care of it for you.

Bill Gates: 1. No one will ever need any more then 1.

TRS-80 Computer Programmer: One is prime, Two is prime, Three is prime, Out of
Memory

Software tech support operator: Well, we haven't had any reports of
composite odd numbers... do you have the latest version of ZFC?

Logician:
Hypothesis: All odd numbers are prime
Proof:
1) If a proof exists, then the hypothesis must be true
2) The proof exists; you're reading it now.
From 1 and 2 follows that all odd numbers are prime

Confused Undergraduate: Yes, it's true. Proof: Let p be any prime
number larger than 2. Then p is not divisible by 2, so p is odd. QED

Linguist: 3 is prime, 5 is prime, 7 is prime, 9 aaah. I can make 9 a prime.
Linguist: are you lot going to shut up and buy me a beer or not?

Philosopher : why don't we just call all the odd numbers prime and call
all the prime numbers odd, that way all the odd numbers would be prime

Philosopher: 3 is prime. Hum, thats an interesting statment, I'll get
one of my research students to look into that.

Economist: "Assume 9 is prime..."
Economist: 2 is a prime, 4 is a prime.

Theologian: 3 is prime and that's good enough for me!

The Psychiatrist: 1 is prime, 3 is prime, 5 is prime, 7 is prime, 9 is prime
but trying to supress it, 11 is prime......

Shrink: 3 is prime, 5 is prime etc... And how could one specify "prime" anyway?

Sociologist: 3 is a number, 3 is prime, all numbers are prime.

Lawyer: 3 is prime, yet 5 could be anything, taking into account, but not
limited to, the fact that 4 may or may not be prime, depending on the
witnesses' testimonies and the written evidence furnished.

Accountant: 3 is prime, 5 is prime, 7 is prime, 9 is prime, deducing 10%
tax and 5% other obligations.

Politician: 3 is prime, 5 is prime, 7 is prime, 9 is composite, 11 is
prime -- we can ignore 9 because the primes have a majority.

Manager: 3 yes, 5 yes, 7 YES, 9 Now let's take a positive attitude here

QA: 1 is not proven, 2 no and reported, 3 not proven, 4 no and reported,
...

Butcher: Prime? What do numbers have to do with meat?

Crank: 9 IS PRIME! NOW WHERE IS THE CAPS UNLOCK?

XWindows Dock

Introducing the XWindows Dock

XWindows Dock - or XWD for short - is the newest free Windows Vista and XP program of the class Application Launcher and Desktop Organizer. But it's not just another one: it's the result of years of use and observation of the many dock programs on the market, plus all functions you only dreamed that your dock would offer!

Sure some of the other ones are good, but none has all the functionalities XWindows Dock has for turning your user experience more productive and fun! Besides, XWD is in active development so that new functionalities are added at each new release.

No other Windows application of this class has so many graphical subtleties such as reflections, transparencies, shadow and blur in a single package, even less in a single free package. No Advanced, Plus or Enhanced version for tasting the real goods. Stacks, Lists and its exclusive Galleries are all there waiting for you!

If you want to destroy the world, don't bother building a hydrogen bomb, just steal some self-replicating nanobots and cover the Earth in a layer of all-consuming grey goo.

That's the moral of a hilarious video, which appeared this morning on the Mental Floss website.

"It was created with cutting-edge motion capture technology (which is why it took so darn long), and it dramatizes one of my favorite chapters of the book: How to Destroy Civilization with Nanotechnology", says Ransom Riggs, who directed the dark cartoon.

His film may be a comedy, but it raises a serious question: Is anyone afraid of nanotechnology?

Several teams of social scientists are hard at work, trying to answer that question, and movies like this could turn their world upside down.

Are there dead bodies on Mount Everest?

Mount­ Everest is the h­ighest point on planet Earth. Because of this unique distinction, humans have been climbing it since Sir Edmund Hillary's first successful ascent in 1953. The peak of Everest is located in Nepal and stands tall at 29,035 feet (8,850 meters) above sea level [source: mnteverest.net]. The mountain itself shares a border with both Nepal and Tibet. Because of the severe weather at the summit, climbers rarely attempt to complete the trek outside of the May to June window, when the jet stream is pushed north. Even then, the weather is pretty inhospitable. An average day in May 2008 saw a high temperature of minus 17 degrees Fahrenheit (minus 27 degrees Celsius) and winds of 51 miles (81 km) per hour [source: USA Today].
At other times during the year, the jet stream passes directly by the summit and winds can blow at hurricane strength -- 118 miles (189 km) per ho­ur -- and temperatures can dive as low as minus 100 degrees Fahrenheit (minus 73 Celsius) [source: teameverest03.org]. Add to this the fact that there's less than one-third the amount of oxygen in the air compared to sea level, and you can see why Everest adventurers have their work cut out for them.

Still, this doesn't stop the adventurous spirit. The downside to having that spirit is that it could lead to your death. Everest News estimates that, as of 2004, more than 2,000 people had successfully reached the summit, while 189 died trying. If you're one of the roughly 150 people to attempt to scale Mount Everest in this year, there's something you'll be sure to see along the way -- dead bodies.
