The Caminito del Rey walkway
Right above is a video showing a walk-through of the "Caminito del Rey" on the way to one of the best climbing spots in Europe at El Chorro, Spain. Also known as the Camino del Rey (which means "the king's path"), this walkway is definitely not for the acrophobic. This guy seems to casually stroll through it. This place is like something out of Myst ... only for real. Yikes! And it's only after this that you start the actual climbing. Enjoy (from the safety of your armchair)! :)

The Hydroptere again ...
... as one fine day in 2007 ... it casually breaks its first world speed record ... to then dominate sailing for the decade to come.

Musica Universalis
Musica Universalis (the movements of the celestial bodies as music)
Kepler wrote:
"The heavenly motions ... are a continuous song for several voices, perceived not by the ear but by the intellect, a figured music which sets landmarks in the immeasurable flow of time."
It is however possible to translate that which Kepler saw as only perceivable by the intellect to also be perceivable by the ear.
Whenever a soundwave is doubled or halved in frequency, it retains the 'flavour' of the original pitch. This can be applied to any periodic cycle, including the orbits of the planets (method explained:

In 2006, Greg Fox took the above orbital periods and divided them until their frequencies fell within the human acoustic range. This gave him six octaves of "planetary notes" for each planet. He called the resulting “music”: “Carmen of the Spheres”. It can be heard and downloaded at:

Thanks to Alcibiades for that one!

Closest approach took place on 13 November 2007. Rosetta sped past at 45 000 km/h (about 12.5 km/s) relative to Earth. The increased energy from this Earth swing-by will help Rosetta cross the asteroid belt for a second time, observe Lutetia (its second target asteroid) and finally rendezvous with comet 67/P Churyumov-Gerasimenko. The rendezvous will take place about 4 astronomical units or 600 million km from the Sun, in 2014.
During this Earth swing-by, a few experiments both on the orbiter and the Philae lander were activated for calibration, scientific measurements and imaging. Rosetta first pointed to Earth and then to the Moon for the observations. ESAMonday, October 29, 2007

Who's ever heard of Stanislav Petrov?
The date is 1 September 1983 and the Cold War between the Soviet Union and USA is in full gear, when from the New York skies Korean Air Lines Flight 007 flies from JFK, destination Seoul, South Korea.
In the middle of the flight, while accidently passing through Soviet air space, Soviet fighter jets appear getting close the aircraft. The Soviets, who didn't know the plane contained civilians, warned the pilot that they will shoot down the aircraft if it doesn't identify itself, and the pilot, for some unknown reason, doesn't respond.
Reports say the pilot never actually received the information, although theories about this are still unclear. An hour passes as the fighter jets still accompany the aircraft, and the orders from Soviet military is to shoot down the aircraft just as the plane was leaving Soviet airspace.
The Soviet fighter jets shot down the plane, with the aircraft plunging 35,000 feet in less than 90 seconds, killing 269 civilians, including a US congressman.
Hell broke loose. As the Soviets tried to defend their 'mistake', US President Ronald Raegan described the Soviets actions as "barbaric" and "a crime against humanity that must never be forgotten".
The tension between the two mega-powers hit an all-time high, and on 15 September 1983 the US administration banned Soviet aircrafts from operating in US airspace. With the political climate in dangerous territory, both US and Soviet government were on high-alert believing an attack was imminent.
It was a cold night at the Serpukhov-15 bunker in Moscow on 26 September 1983 as Strategic Rocket Forces lieutenant colonel Stanislav Yevgrafovich Petrov resumed his duty, monitoring the skies of the Soviet Union, after taking a shift of someone else who couldn't go to work.
Just past midnight, Petrov received a computer report he'd dreaded all his military career to see, the computer captured a nuclear military missile being launched from the US, destination Moscow.
In the event of such an attack, the Soviet Union’s strategy protocol was to to launch an immediate all-out nuclear weapons counterattack against the United States with nuclear power, and immediately afterwards inform top political and military figures. From there, it would be taken a decision to further the military offensive on America.
The bunker was in full-alarm, with red lights all over the place as the missile was captured by the Soviet satellites via computers. Petrov wasn't convinced though. He believed that if the US attacked, they would have attacked all-out, not just sending one missile and giving a chance for them (the Soviets) to attack back.
Petrov figured something didn't make sense, as strategically, just one missile from the US would be a strategic disaster. He took some time to think and decided not to give the order a nuclear attack against America, since in his opinion, one missile didn't make sense strategically and it could easily have been a computer error.
But then, seconds later, the situation turned extremely serious. A second missile was spotted by the satellite. The pressure by the officers in the bunker to commence responsive actions against America started growing. A third missile was spotted, followed by a fourth. A couple of seconds later, a fifth one was spotted... everyone in the bunker was agitated as the USSR was under missile attack.
He had two options. Go with his instinct and dismiss the missiles as computer errors, breaking military protocol in the process or take responsive action and commence full-blown nuclear actions against America, potentially killing millions.
He decided it was a computer error, knowing deep down that if he was wrong, missiles would be raining down in Moscow in minutes.
Seconds turned to minutes, and as time passed it was clear Petrov was right, it was a computer error after all. Stanislav Petrov had prevented a worldwide nuclear war, a doomsday scenario that would have annihilated entire cities. He was a hero. Those around him congratulated him for his superb judgment.
Upon further investigation it resulted that the error came from a very rare sunlight alignment, which the computer read as missile.
Of course, top brass in the Kremlin didn't find it so heroic, as he broke military protocol and if he would have been wrong, risked millions of Russian lives. He was sent into early retirement, with a measly $200 a month pension, suffering a nervous breakdown in the process.
Due to military secrecy, nobody knew Petrov's heroic judgment until 1998, when a book written by a Russian officer present at the bunker revealed that World War 3 was closer than people thought, and a nuclear holocaust was avoided by a close shave.
Even though the Russian have little sympathy to the man who saved millions of American lives, the United Nations and a number of US agencies honoured the man who could have started a nuclear war, but didn't.
In 2008, a documentary film entitled 'The Man who saved the World' is set to be released, perhaps giving Petrov some financial help, thanking him for the incredible part he had in keeping the US and the USSR out of a full-blown war.
Without knowing on the cold Moscow night back in 1983, a badly paid 44 year old military officer saved the world, and made himself one of the most influential persons of the century in the process, saving more lives than anyone ever did.
Most of today's people don't know it, but today's world as we know it, is like it is because of Stanislav Petrov.

The Hydroptère
Alain Thebault does it again. He and his crew have already broken the 50-mph barrier, with a run that topped out at 54 mph (47.2 knots). We are not talking a windsurf here but a full-fledged D-class sailship!
That thing can average a speed of 41.69 knots/h for at least one nautical mile and reach speeds of 44,5 knots/h for at least 500 meters … beating thus two world speed records so far, including the one held since 1997 by the catamaran “Techniques Avancées”. It broke these records in 25-knot winds ... that’s right … meaning that it can speed considerably faster than the wind propelling it. The physics of that just have to be awesome!
It’s called the Hydroptère … a Greek name indicating water and wing … iow … the “WaterWing”.
And it's the fastest sailboat in the world.Monday, August 27, 2007
The NASA Photo of the Fires
The whole of Attica smells like a fireplace. Over 60 people have died. The few once-green parts of Southern-Greece have now also taken the cement-grey colour of Athens. Ashes spread everywhere ... beyond the centre of the city ... even to the beach-side community where I live. Only a few places were saved ... and this because the people there had figured soon enough that ... the lack of snows in the past winter, the lack of rains in May, the heat and the winds were just too dangerous. Some villages had thus organised themselves into 24 hour patrols in shifts: the women until midnight and the men after that. They also assigned some people to the top of mountains with binoculars. Where this was done, fires were extinguished before spreading ... but even then barely so.
You see ... these fires were arson ... as in ... they were started on purpose! The motivation behind this is still a mystery. One cannot even begin to imagine what kind of sick persons would do this ... but there you have it ... they did. In any case ... with the start of hunting season ... these patrols will now have the added factors of shotguns.
In the meantime, there is even talk of cancelling the upcoming elections. It won't happen of course. But it just goes to show you.
