the extensive sheets of mica

Mica does not leap to mind as an obvious general-purpose flooring material. Its use to form layers underneath a floor, and thus completely out of sight, seems especially bizarre when we remember that no other ancient structure in the Americas, or anywhere else in the world, has been found to contain a feature like this.5

It is frustrating that we will never be able to establish the exact position, let alone the purpose, of the large sheet that Bartres excavated and removed from the Pyramid of the Sun in 1906. The two intact layers in the Mica Temple, on the other hand, resting as they do in a place where they had no decorative function, look as though they were designed to do a particular job.

Let us note in passing that mica possesses characteristics which suit it especially well for a range of technological applications. In modern industry, it is used in the construction of capacitors and is valued as a thermal and electric insulator. It is also opaque to fast neutrons and can act as a moderator in nuclear reactions.
The trace elements in Teotihuacan’s Mica Temple indicate that the underfloor sheets belong to a type which occurs only in Brazil, some 2000 miles away.

I can't help but notice...

it's thermally stable to 500 °C, and is resistant to corona discharge. Muscovite is the principal mica used by the electrical industry and is used in capacitors that are ideal for high frequency and radio frequency. Phlogopite mica remains stable at higher temperatures (to 900° C) and is used in applications in which a combination of high-heat stability and electrical properties is required. Muscovite and phlogopite are used in sheet and ground forms.


Huge sheets of mica have also been found in front of the Abu Ghurab pyramid which is part of the pyramid complex at Abu Sir south of Cairo.

What a surprise both Einstein and Tesla studied it. :shock: I'm shocked they've kept this from us. :lol: (just kidding, I've know about the rumours for donkey's years.)

Laws of photoelectric emission:Wiki n.p.

1. For a given metal and frequency of incident radiation, the rate at which photoelectrons are ejected is directly proportional to the intensity of the incident light.
2. For a given metal, there exists a certain minimum frequency of incident radiation below which no photoelectrons can be emitted. This frequency is called the threshold frequency.
3. Above the threshold frequency, the maximum kinetic energy of the emitted photoelectron is independent of the intensity of the incident light, but it depends on the frequency of the incident light.
4. The time lag between the incidence of radiation and the emission of a photoelectron is very small, less than 10-9 seconds.
When E-M radiation falls on an insulated conductor connected to a capacitor, the capacitor charges electrically. Nikola Tesla described the photoelectric effect in 1901. He described such radiation as vibrations of aether of small wavelengths which ionized the atmosphere. On November 5, 1901, he received the patent that describes radiation charging and discharging conductors (e.g., a metal plate or piece of mica) by "radiant energy". Tesla used this effect to charge a capacitor with energy by means of a conductive plate, which was a solar cell precursor. The radiant energy threw off with great velocity minute particles, i.e., electrons, which were strongly electrified. The patent specified that the radiation (or radiant energy) included many different forms. These devices were called "photoelectric alternating current stepping motors". In practice, a polished metal plate in radiant energy, e.g. sunlight, will gain a positive charge as electrons are emitted by the plate. As the plate charges positively, electrons form an electrostatic force on the plate because of surface emissions of the photoelectrons and "drain" any negatively charged capacitors. As the rays or radiation fall on the insulated conductor connected to a capacitor, the condenser will indefinitely charge electrically. Wiki n.p.

Albert Einstein's showed a mathematical description in 1905 of how the photoelectric effect was caused by absorption of quanta of light (photons). This paper proposed the simple description of "light quanta," or photons, and showed how they explained such phenomena as the photoelectric effect. His simple explanation in terms of absorption of single quanta of light explained the features of the phenomenon and the characteristic frequency. Einstein's explanation of the photoelectric effect won him the Nobel Prize in Physics in 1921. The idea of light quanta began with Max Planck's published law of black-body radiation by assuming that Hertzian oscillators could only exist at energies E proportional to the frequency f of the oscillator by E = h•f, where h is Planck's constant. By assuming that light actually consisted of discrete energy packets, Einstein wrote an equation for the photoelectric effect that fit experiments. This was an enormous theoretical leap, but the reality of the light quanta was strongly resisted. The idea of light quanta contradicted the wave theory of light that followed naturally from James Clerk Maxwell's equations for electromagnetic behavior and more generally, the assumption of infinite divisibility of energy in physical systems. Even after experiments showed that Einstein's equations for the photoelectric effect were accurate, resistance to the idea of photons continued, since it appeared to contradict Maxwell's equations, which were well understood and verified. Einstein's work predicted that the energy of the ejected electrons increases linearly with the frequency of the light. In 1905 it was known that the energy of the photoelectrons increased with increasing frequency of incident light and independent of the intensity of the light. However, the manner of the increase was not experimentally determined to be linear until 1915 when Robert Millikan showed that Einstein was correct. Wiki n.p.

I had not heard that - very interesting indeed.

There will be a programme about this on Channel 4 in the UK next weekend, 8pm on Sunday 10th November, in the slot freed up by the brilliant Yeti series which concluded last night. I saw a preview yesterday and it looks interesting.
