Beamlines To Reveal Secrets of the Mummies

Hugh Pickens writes "A British X-ray with a light ten billion times brighter than the sun is to be used to reveal the secrets of statues, mummies, sarcophagi and other ancient artifacts to analyze their composition and how they were made. Three Egyptian bronze figurines from the British Museum will be among the first treasures to be investigated by the Joint Engineering, Environmental and Processing beamline, or Jeep, using intense radiation known as synchrotron light which allows scientists to see through solid objects and to show structural details that cannot be seen by standard X-rays. 'It might give us the chance to look at the contents. The Egyptians used to stash things inside their statues. We also get very fragile inner sarcophagi or mummy wrappings,' says Jen Hiller, a scientist working on the beamline. In Grenoble a team has used synchrotron radiation to discover the first known fossilized brain, of a fish-like creature; details are to be published this month. In California it is being used to decipher the Archimedes palimpsest — a text by the Greek mathematician that was overwritten in medieval times."

    I assume the "10 billion times brighter then the sun" is an apparent brightness measurement of the sun at the earth, and not of the suns actual luminosity. If it is actually that much brighter then the sun, then that's REALLY impressive...

  2. Mummy question by BigHungryJoe · · Score: 3, Interesting

    Every once in a while, I'll hear someone say -

    "Autopsies performed on the remains of mummies show that they had cocaine alkaloids in their system, which means that the ancient Egyptians traveled to South America"

    I've always suspected that was complete hogwash. I would appreciate it if someone would shed some light on THAT mummy mystery.

      Chemical evidence of tobacco has been found in ancient Egyptian mummies, although tobacco was supposed to be unknown in the Old World prior to Columbus. First, fragments of tobacco were found deep in the abdominal cavity of the 3200-year-old mummy of Pharaoh Ramses II while it was being studied in a European museum. Some skeptics immediately concluded that this had to be due to modern contamination in the museum. This American plant could not possibly have been known in Egypt, they insisted. In 1992 physical scientists in Germany used sophisticated laboratory instrumentation to test nine other Egyptian mummies. They found chemical residues of tobacco, coca (another American plant, the source of cocaine), and the Asian native hashish (the source of marijuana) in the hair, soft tissues, skin, and bones of eight of the mummies. These traces included cotinine, a chemical whose presence means that the tobacco had been consumed and metabolized while the deceased person was alive. (The ninth mummy contained coca and hashish residues but not tobacco.) Dates of the corpses according to historical records from Egypt ranged from 1070 BC to AD 395, indicating that these drugs were continuously available to some Egyptians for no less than 1,450 years. Investigators have since found evidence of the drugs in additional mummies from Egypt.

      Well, the Norwegian adventurer Thor Heyerdahl (http://en.wikipedia.or/wiki/Thor_Heyerdahl) believed that it was possible for the ancient Egyptians to sail to South America. He built a raft out of papyrus reeds and had a couple of goes at it, himself.

      Whether the ancient Egyptians actually undertook such a journey, and came back with their luggage stuffed with cocaine, is a matter for pure speculation.

      While the chemical traces are intriguing... a complete and utter lack of corroborating evidence (I.E. remains of plants in the tombs, records of their growth, examples in tomb or temple paintings, surviving examples, etc. etc.) renders them suspect.
       
      Hmm... a quick google search leads me to the page you cut and pasted the above from - a page from an organization with a vested interest in finding evidence of cross pollination from the New World to the Old. I can find no other mentions of the first paper. The second paper, I can find references to - mostly defenses against debunkers, and curiously the defense consists mostly of "the chances of error are infinitesimal, and since the chances of error are so small we can assume that there are no errors".

    I was at Diamond last weekend, and while idling around the foyer I was having a look at their big posters boasting about how bright their beam was. A closer look at the units indicated that it's even more abstract than "photons per unit area". The units they're talking about are (deep breath...) "Photons per second per square millimetre per millirad per 0.1% beam width". So they're not only counting area, but also divergence and how well-defined the beam is. All things the sun tends to be rather poor at, really, so it's not the fairest comparison ever.
