In many ways, this preface by von Kupffer remains relevant today, as the argument between von Kupffer and Hirschfeld mirrors later similar arguments, e. g. between Adolf Brand and Hirschfeld, or since the 1960s, between advocates of pederastic relationships and the mainstream gay liberation movement.

J. N. Lockyer's passing reference to a colleague's suggestion that electric lamps would explain the absence of lampblack deposits in the tombs has sometimes been forwarded as an argument supporting this particular interpretation ( another argument being made is the use of a system of reflective mirrors ).

The creator trusts his intuition to lead him along a path that has internal validity because it mirrors the reality of his experience.

The consciousness it mirrors may have come earlier to Europe than to America, but it is the consciousness that most `` mature '' societies arrive at when their successes in technological and economic systematization propel them into a time of examining the not-strictly-practical ends of culture.

They demonstrate, explain, and analyze a student's moment to moment responses as well as using mirrors, video feedback or classmate observations.

In the third book, Dürer gives principles by which the proportions of the figures can be modified, including the mathematical simulation of convex and concave mirrors ; here Dürer also deals with human physiognomy.

" But of the specific production, the reviewer went on to note: " But Nunn's production, on one of those hermetic sets largely consisting of doors and tarnished mirrors that have become such a cliché in recent years, never penetrates the work's subtly erotic heart.

It was one of the principal seats of the glass industry in Indiana – plate glass, lamp chimneys, mirrors, & c., were once manufactured here.

Burning mirrors achieve a similar effect by using reflecting surfaces to focus the light.

Plutarch refers to a burning mirror made of joined triangular metal mirrors installed at the temple of the Vestal Virgins.

For this they used the sun's rays focused with mirrors or lenses and not impure triggers.

Archimedes, the renowned mathematician, was said to have used a burning glass ( or more likely a large number of angled hexagonal mirrors ) as a weapon in 212 BC, when Syracuse was besieged by Marcus Claudius Marcellus.

The pop science TV program MythBusters attempted to model Archimedes ' feat by using mirrors to ignite a small wooden boat covered with tar, with only partial success — they found it too difficult to focus light from their hand-held mirrors onto a point small enough to ignite the boat.

In 1796, during the French Revolution and three years after the declaration of war between France and Great Britain, Étienne-Gaspard Robert met with the French government and proposed the use of mirrors to burn the invading ships of the British Royal Navy.

They sometimes employ a large parabolic array of mirrors ( some facilities are several stories high ) to focus light to a high intensity.

The funeral mirrors the use of funeral offerings for the dead with extravagant possessions in Scyld's funeral.

It is able to hold a good polish and so is sometimes used in light reflectors and mirrors.

The cemeteries of the period in Bologna contain La Tène weapons and other artifacts, as well as Etruscan items such as bronze mirrors.

A similar musical device is used on BBC Radio 5 Live, and mirrors the pips on BBC Radio 4.

" However, held the Cadillac court, " one who manufactures articles dangerous only if defectively made, or installed, e. g., tables, chairs, pictures or mirrors hung on the walls, carriages, automobiles, and so on, is not liable to third parties for injuries caused by them, except in case of willful injury or fraud ,"

A level 2 signature is highly analogous to the trust assumption users must rely on whenever they use the default certificate authority list ( like those included in web browsers ); it allows the owner of the key to make other keys certificate authorities.

In 1979, Michael O. Rabin published a related cryptosystem that is provably secure, at least as long as the factorization of the public key remains difficult-it remains an assumption that RSA also enjoys this security.

In cryptography, Kerckhoffs's principle ( also called Kerckhoffs's Desiderata, Kerckhoffs's assumption, axiom, or law ) was stated by Auguste Kerckhoffs in the 19th century: A cryptosystem should be secure even if everything about the system, except the key, is public knowledge.

One of the key differences between catastrophism and uniformitarianism is that to function, uniformitarianism requires the assumption of vast time-lines, whereas catastrophism can function with or without assumptions of long timelines.

The key assumption is that capital and labor are not available in the same proportions in the two countries.

The key assumption used in deriving the BET equation that the successive heats of adsorption for all layers except the first are equal to the heat of condensation of the adsorbate.

For provable security this reliance on something external to the system has the consequence that any public key certification scheme has to rely on some special setup assumption, such as the existence of a certificate authority.

War Plan Red first set out a description of Canada's geography, military resources, and transportation, and went on to evaluate a series of possible pre-emptive American campaigns to invade Canada in several areas and occupy key ports and railways before British troops could provide reinforcement to the Canadians-the assumption being that Britain would use Canada as a staging point.

The key assumption behind all sustainable harvesting models such as MSY is that populations of organisms grow and replace themselves – that is, they are renewable resources.

Chosen as Gaiman's replacement, John Ney Rieber discovered that a gaming guide to the DC universe had made this assumption, and worried that a key part of the Tim Hunter character-that he was a normal teenage boy-might be lost if this was true.

The solution to the inadvertent assumption problem is to generate a random primary key.

Even though the system sometimes failed to decrypt, the developers considered it a public key cryptosystem and thereby based their security claims on the assumption that this system was a public key cryptosystem.

However the key assumption he made in formulating the collision term was " molecular chaos ", an assumption which breaks time-reversal symmetry as is necessary for anything which could imply the second law.

This protocol allows two parties to generate a key only known to them, under the assumption that a certain mathematical problem ( e. g., the Diffie – Hellman problem in their proposal ) is computationally infeasible ( i. e., very very hard ) to solve, and that the two parties have access to an authentic channel.

The argument that 2 / 3 should be the correct scaling factor is based on the assumption that energy dissipation across the surface area of three dimensional organisms is the key factor driving the relationship between metabolic rate and body size.

Previously, no one had paid any attention to the different operations used because they always produced the same results, but the key insight of Einstein was to posit the Principle of Equivalence that the two operations would always produce the same result because they were equivalent at a deep level, and work out the implications of that assumption, which is the General Theory of Relativity.

A key assumption made in early COX-2 cost-effectiveness studies was lower cost due to a reduction in coprescription of agents used to protect the gastrointestinal tract from traditional NSAIDs.

The key data-dependent term Pr ( D | M ) is a likelihood, and represents the probability that some data is produced under the assumption of this model, M ; evaluating it correctly is the key to Bayesian model comparison.

They can focus just on the assigned smaller task ( this, it is claimed, counters the key assumption of The Mythical Man Month – making it actually possible to add more developers to a late software project – without making it later still ).

But it is this key assumption that Dreyfus denies.

Another key philosophic assumption is atomism.
