Digital Forensics: Spotting Forgeries and Fake Photos


This month's Scientific American has a special section on "digital forensics." Among the areas covered:

How experts uncover doctored images (look for the ducks?).

Five ways to spot a faked photo.

Altered Lance Armstrong photo explained.

Photo tampering throughout history (slideshow).

I tried to get a hold of Dan Rather for this story, but he was unavailable for comment.

Unearthing the secrets of Stonehenge


CNet:

Now that's a pretty impressive tombstone...

New research suggests that Stonehenge was used as a cemetery for more than 500 years, much longer than previously thought...

The new findings also show that people used the area as a burial site long before placement of its trademark stones (or sarsen stones) was complete.

I always took Stonehenge for granite...

Heh.

Michelin's transparent tire


Chris sends us a Radical new tire design by Michelin.

This is the next generation of tires. They had a pair at the Philadelphia car show.

These tires are airless and are scheduled to be out on the market very soon. The bad news for law enforcement is that spike strips will not work on these tires.

This is what great R&D will do, and just think of the impact on existing technology: a. no more air valves; b. no more air compressors at gas stations; c. no more repair kits.





These pictures were taken at Michelin's South Carolina plant.

It will be a while before they are available to the automotive industry.

Believe me, I checked Snopes and they don't have anything up on this yet. So it's gotta be accurate!

The face of Caesar


The London Times.

The world has been introduced to the true face of Julius Caesar with the discovery in a river in southern France of a bust that was sculpted in the lifetime of the Roman leader... The marble sculpture, found in the bed of the Rhône in the town of Arles, has been authenticated as a realistic likeness of Caesar, wrinkled and balding in his fifties and probably modelled from life.

“It is the only known bust of the living Caesar, except for the Mask of Turin, which was made just before or after his death, said Luc Long, the Ministry of Culture archaeologist who found it along with other treasures last autumn. “Even in Rome, no one has found a portrait of the living Caesar,” he added.

The bust, which has a broken nose, dates from between 49 and 46BC, the period when Caesar founded the Roman colony of Arles, to thank the town for helping him to conquer the nearby port of Marseille. Caesar used Arles as a base for his campaign against Pompey, his rival...

Macenstein: Apple's Ergonomics Page predates the Internet


And he's not joking.

If I had to use a pair of 5.25-inch floppy drives as primary storage, lightning bolts might fly out of my neck, too.

Scientists near discovery of 'God particle'

 
Mark Henderson, of the London Times:

The 40-year hunt for the holy grail of physics – the elusive “God particle” that is supposed to give matter its mass – is almost over, according to the leading scientist who first came up with the theory... Peter Higgs, whose work gave his name to the elusive Higgs boson particle, said that he was more than 90 per cent certain it would be found within the next few years.

The Higgs boson was the professor’s elegant 1964 solution to one of the great problems with the standard model of physics – how matter has mass and thus exists in a form that allows it to make stars, planets and people. He proposed that the universe is pervaded by an invisible field of bosons that consist of mass but little else.

As particles move through this field, bosons effectively stick to some of them, making them more massive, while leaving others to pass unhindered. Photons, light particles that have no mass, are not affected by the Higgs field at all...

The folks at FermiLab have more on Higgs-Boson in what they assert is plain English.
