Answer: Exciting news if you’re an ancient history buff!
Researchers in Italy have found a way to read ancient scrolls thought to be irreparably damaged in the Mt. Vesuvius explosion that destroyed or damaged Pompeii and Herculaneum in 79 A.D.
According to a recent article in ECN, the scrolls were recovered from a Roman villa that may have belonged to Julius Caesar’s father-in-law. This is an exciting development since some of the scrolls may have been written by known Greek and Roman writers. Some of the scrolls may have already been 100 years old at the time of the eruption.
Using a modified version of CT X-ray technology, researchers have been able to discern letters in the rolled-up scrolls.
CT stands for Computer Tomography. Tomography is the method by which images are sliced. The 2D slices are converted and assembled into 3D images, which is where the computer comes in. We’ve all seen them….Here is an example of another use in an historical application – a CT image of King Tut’s head obtained in early 2005.
Okay, back to Italy…..The 300 or so scrolls in the villa were originally recovered in the late 1700's. They are extremely fragile, but interestingly enough, instead of being burned to a crisp, the scrolls were carbonized by the hot gases from Mt. Vesuvius.
Anyway, this is a great example of what happens when cross-fertilization occurs between two different disciplines – science and history. We all win.
I’m looking forward to reading more about the scrolls, and what they might reveal about life almost 2000 years ago in present-day Italy. Good science is hard to beat, eh?
High Voltage Diodes for X-ray Power Supplies
Oh, and by way of mentioning high voltage diodes, they are useful in high voltage power supplies that power x-ray systems. Diode requirements varying, depending on the X-ray application. Industrial x-ray applications use high voltage, high current diodes like the Z- or K-body diodes. Medical and dental x-ray apps typically use high voltage, low current diodes like M- or X-body diodes.
