Efforts to magnify objects in the sky probably began with the use of crystal lenses. "Lens-shaped crystals have long been known from Bronze Age contexts"[1]. These are "usually recognized as short-focus magnifying lenses."[1]

The slightly oval lens [40 x 35 mm] has been roughly ground and has a focal point about 110 millimetres (4.5 in) from the flat side.[2][3]

Lenses are typically made of glass or transparent plastic. This glass is usually "about 75% silica (SiO2) plus Na2O, CaO, and several minor additives. Glass does not contain the internal subdivisions associated with grain boundaries in polycrystals and hence does not scatter light in the same manner as a polycrystalline material. The surface of a glass is often smooth since during glass formation the molecules of the supercooled liquid are not forced to dispose in rigid crystal geometries and can follow surface tension, which imposes a microscopically smooth surface.

"There is in reality a distribution of magnetic cluster sizes although the smallest magnetic clusters will constitute the dominant group."[7]

"The dominant group is (SiGe)SiH, at T, = 190 "C and is replaced by (Ge,)SiH, at T, = 250 "C."[8]

"Then, metallurgical reactions occur between the fuel slug and the cladding. ... Lanthanide elements, a dominant group of fission products, will be less significant because the solubility of lanthanide elements in the U—Pu—Zr alloys is limited (~O.6 wt% or less)(9) and the eutectic point in the binary system of any lanthanide element and Fe is higher than that in the Pu—Fe system"[9].

"The different settlement ceramic assemblages present dominant technical sub-groups, which are different in aspect from one site to another (tab. 3). ... The ceramic entity A is characterised, from a technical and techno-petrographic point of view, by a discontinuity between one or two dominant sub-groups (quantitatively major) and a few satellite sub-groups (quantitatively minor). Ceramic entity B, on the contrary, shows a petrographic continuity with the dominant sub-groups A."[11]

"Among a variety of tool making materials, sintered carbides are still a dominant group in view of machining technologies. ... Having considered all types of coating materials, the most numerous group is made up by materials with the predominant number of metallic bonds."[12]

"Our theory applies to parameters (to be identified below) for which the second group is dominant, allowing for the third group, labeled ψrem (mnemonic remainder) to be neglected in the calculation of the saddle-points."[21] "The dominance requirement constrains the remaining (first and third) terms of ψrem to be significantly smaller than the terms of the second group along the contour of integration. Since the two terms of the dominant group have comparable magnitudes, it suffices to make the comparison with only the second term in the dominant group."[21]

"Such work indicated that group III interdiffusion in InGaAs/InP is associated with a redshift, while a blueshift is associated with a dominant group V interdiffusion."[22]

"This likely is the result of the fact that the six-membered ring group becomes the dominant structural group in the vicinity of x = 0.5, whereas the tetrahedral boron group is becoming the least prominent structural group in the glass."[28]

"In the other series of glasses, Li, Na, and K, in particular, that can be formed out to x = 0.75, the IR spectra clearly show that this structural group becomes the dominant group in the glass at this composition [4,5,43]."[28]

On the right is a katana of the kobuse type is made in the traditional Japanese style.

"The hardened edge is separated from the softer back by a bright, wavy line, called the nioi. The edge of this bright line, called the hamon, marks the boundary between the martensitic portion (the yakiba) from pearlitic center area (the hira). The wavy shape of the hamon is from the manner in which the insulating clay was appllied before quenching. The inset shows a close-up of the nioi, which is made up of niye. The niye are single, bright grains of martensite surrounded by pearlite, which are seen as the speckled zone between the bright yakiba and the darker hira. The wood-grain appearance comes from alternating layers of steel that have different hardenability."[32]

The "calibration of radiocarbon dates at approximately 2500-2450 BP [2500-2450 b2k] is problematic due to a "plateau" (known as the "Hallstatt-plateau") in the calibration curve [...] A decrease in solar activity caused an increase in production of 14C, and thus a sharp rise in Δ 14C, beginning at approximately 850 cal (calendar years) BC [...] Between approximately 760 and 420 cal BC (corresponding to 2500-2425 BP [2500-2425 b2k]), the concentration of 14C returned to "normal" values."[56]
