Megalithic or 366 Geometry.

According to hypothesis of Alan Butler and Christopher Knight, megalithic civilization of Britain and Britanny, France used  366-degree geometry (also called megalithic geometry). This geometry, whose origin is claimed to go back to c. 3,000 BC, would have used a 366-degree circle rather than a 360-degree circle as we do today. Alan Butler also asserts that 366-degree geometry has been materialised on the Earth by what he terms Salt Lines – 366 meridians and 183 parallels crisscrossing the globe at regular intervals (the equivalents of modern-day 360 meridians and 180 parallels).

Butler and Knight claim that the Megalithic Yard is a fundamental number for the Sun, the Moon and the Earth. The Megalithic arc second as measured on the Earth equator is very close to 366 Megalithic Yards, while the lunar Megalithic arc second as measured on the Moon equator is very close to 100 Megalithic yards, and the solar Megalithic arc second as measured on the Sun equator is very close to 40,000 Megalithic Yards.

French author Sylvain Tristan suggests that the numbers 366, 40 and 10 are not only fundamental to the Earth, the Moon and the Sun, but also to the human body and water. In the water-based Celsius temperature measurement system, which is directly linked to base-10 numeration, the average human body temperature is 36.6 degrees. On a scale where the absolute zero is defined as being minus 1,000 degrees, water boils at the temperature of 366 degrees, which points at something intrinsically fundamental in these numbers.

Alan Butler also asserts that 366-degree geometry has been materialised on the Earth by what he terms Salt Lines – 366 meridians and 183 parallels crisscrossing the globe at regular intervals (the equivalents of modern-day 360 meridians and 180 parallels). Most of the world’s capital cities or sanctuaries of late prehistory and antiquity are located on the course of Salt Lines: it includes Stonehenge, Avebury, Babylon, Assur, Niniveh, Thebes, Abu Simbel, Harappa, Mycenae, Athenes, Hattusa, Alesia, Teotihuacan, Chichén Itzá, Tiwanaku and Caral. According to the author, such a situation challenges probability laws and can hardly been explained away by chance only, and thus is the result of some common knowledge held by the Megalithic civilisation that might have spread to different parts of the globe.

Working at New Scientist means that every day, I learn something new and fascinating. I have been terribly lax about blogging these amazing discoveries, but here’s one I loved. I never gave much thought to metrology - the science of measurement - but it’s fascinating and really important. Anyway, NS ran a piece this week about how some scientists are lobbying for more precise measurements. I kind of wondered, “What’s the big deal? What’s wrong with our old measurements?” Turns out, A LOT.

“The first sign that the SI was flawed was noticed in 1949 in a check on a lump of metal kept inside a vault at the International Bureau of Weights and Measures (BIPM) in Paris. By definition, it is the only object in existence with a mass of exactly 1 kilogram – one of the seven SI base units – so metrologists were unsettled to discover that this mass had changed.”

I’m sorry, what?! The kilogram is based on some lump of metal somewhere? How archaic. (Sidenote: doesn’t the Bureau of Weights and Measures sound like something from Harry Potter? I totally want to visit there. I picture it like a museum with cases of strange measurement objects.)

Anyway, go on over and read about the changes on the horizon for measurements.

‘Quantum Cheshire Cat’ becomes reality

Scientists have for the first time separated a particle from one of its physical properties - creating a “quantum Cheshire Cat”.

The phenomenon is named after the curious feline in Alice in Wonderland, who vanishes leaving only its grin.

Researchers took a beam of neutrons and separated them from their magnetic moment, like passengers and their baggage at airport security.

They describe their feat in Nature Communications.

Best birthday present EVER! 36 x 48 x 6 granite with stand. Thanks Ashley! Yes it’s heavy.  And what does one do with a giant rock like this? Well, first of all, it’s not a giant rock. It’s a piece of precision measuring equipment, flat to within 0.0004 inches, making it a grade B, which is pretty damn flat. If you hope to make things that are nice and accurate, you need a nice flat accurate place to check and measure them. I’m very happy about my new 1,200 pound baby.

Nanometres in 3D

The method was demonstrated using a football-like structure called a “buckyball”, only 6 thousandths of a millimetre across, which was fabricated with the latest 3D laser technology. In addition to showing the shape of the object, the method allowed the scientists to pinpoint the locations of a specific chemical element (Cobalt) and deduce further information on the environment of its atoms.

What I Spend All My Allowance Money On. ;D

Been getting some upgrades to my measurement equipment over the last few months. Still a work in progress. Need to find a reasonably priced 1" dial indicator to replace the Craftex.

Got some real good brand-name stuff in there now, so I’m much more confident in my measurements. I especially like the hugeass Starrett dial indicator on the upper-right, practically stole it on ebay for $39! And the new digital micrometers, woo… 0.00005" resolution (50 millionths of an inch)!

36 piece set of NIST-traceable precision gage blocks are already on their way and should arrive by tomorrow afternoon. Mmmmm, precision and accuracy. :9

Here’s a list of (most) everything in the photo, in no particular order:

Aerospace dial test indicator, 0-15-0 face 0.0005" resolution 0.045" travel

Mitutoyo 0-6" digital caliper

Starrett dial indicator 0-20 face 0.0001" resolution 0.400" travel

Craftex dial indicator 0-100 face 0.001" resolution 1" travel w/depth gauge adapter

Mitutoyo dial indicator 0-50 face .0005" resolution 0.125" travel

Fowler 0.2-1.2" 0.001" resolution inside micrometer with 0.200" reference standard

Starrett 0-1" and 1-2" digital micrometers, 0.00005" resolution with 1.000" reference standard

Agreement to tie kilogram and friends to fundamentals

The first sign that the SI was flawed was noticed in 1949 in a check on a lump of metal kept inside a vault at the International Bureau of Weights and Measures (BIPM) in Paris. By definition, it is the only object in existence with a mass of exactly 1 kilogram – one of the seven SI base units – so metrologists were unsettled to discover that this mass had changed.

Not liking to rush into anything, however, no one checked the standard kilogram again until 1989. The problem had not gone away.

I am a metrologist by trade, so to convey what that means, and how I spend my working hours here is this fun little picture. The little Mu next to the “m” stands for micro (10^-6). So a Micron is a micrometer (.001 mm.) The Anthrax shown above is .001mm long, and that is the level of accuracy to which I report. The tolerance bands for the dimensions I measure range between the pollen grains at .015mm and the salt grain at .060mm. This is the scale you can expect for most “precision” industrial metrology. Pushing smaller starts you into the realm of nano-metrolgy which is a whole-other ballpark.
