Question: How much does the Eiffel tower sway in the wind?
About the article "Eiffel Tower", section "Wind considerations".

Candidate passages:
"Alec Eiffel" is a tribute to the famous French engineer Alexandre Gustave Eiffel, designer of the Eiffel Tower in Paris.
The song's video features the band playing in a wind-tunnel, a reference to the "pioneer of aerodynamics," with physics formulas in the background. 
 the "Eiffel Tower", a ship wrecked in south Wales in 1894  
Petřínská rozhledna is often described as small version of the Eiffel Tower.
This is, however, not correct, because in contrast to the Eiffel Tower, Petřínská rozhledna has an octagonal and not a square cross section over its whole height.
Further, it does not stand, as does the Eiffel Tower, on four columns of lattice steel, and the whole area under its legs is covered with the entrance hall.
A similarity between the Eiffel Tower and Petřínská rozhledna is the design of the lowest cross beams in the form of round bows.
The two observation platforms are accessible via 299 stairs in sections of 13 per stage running around the inside of the structuring.
The upper level is also served by a lift. 
Structural art is distinct from architecture primarily in that the constraints under which structural artists practice are very different from those under which architects practice.
Structural artists, while seeking elegance, must satisfy safety and serviceability, efficiency and economy, and usage needs.
Architects are somewhat freer in making designs, constrained primarily by usage needs.
Eero Saarinen's Gateway Arch and the Eiffel Tower provide a contrast that illustrates the difference between structural art and architecture.
The Gateway arch is widely thought to be a highly successful work of architecture, and the Eiffel Tower is recognized as a work of structural art.
Both structures must primarily resist wind loads yet have very different forms.
The Eiffel Tower has been shown to be the near optimal form for resisting wind loads, and therefore is more in line with the ideals of structural art than architecture.
The Gateway Arch succeeds as a work of architecture and does not meet the ideals of efficiency and economy.

Like any work of art, also the artistic garden of Ryōan-ji is open to interpretation, or scientific research into possible meanings.
Many different theories have been put forward inside and outside Japan about what the garden is supposed to represent, from islands in a stream to swimming baby tigers to the peaks of mountains rising above the clouds to theories about secrets of geometry or of the rules of equilibrium of odd numbers.
Garden historian Gunter Nitschke wrote: "The garden at Ryōan-ji does not symbolize anything, or more precisely, to avoid any misunderstanding, the garden of Ryōan-ji does not symbolize, nor does it have the value of reproducing a natural beauty that one can find in the real or mythical world.
I consider it to be an abstract composition of "natural" objects in space, a composition whose function is to incite meditation.

Question: What did the tapes reveal?
About the article "Watergate scandal", section "Release of the tapes".

Candidate passages:
News that these analog data tapes were missing broke on August 5, 2006 when the printed and online versions of "The Sydney Morning Herald" published a story with the title "One giant blunder for mankind: how NASA lost moon pictures".
The missing tapes were among over 700 boxes of magnetic data tapes recorded throughout the Apollo program which have not been found.
On August 16, 2006 NASA announced its official search saying, ""The original tapes may be at the Goddard Space Flight Center … or at another location within the NASA archiving system"", ""NASA engineers are hopeful that when the tapes are found they can use today's digital technology to provide a version of the moonwalk that is much better quality than what we have today.""
NASA also had ongoing research reasons for finding these higher resolution tapes, since Project Orion was planned to carry out tasks similar to those of the original Apollo program, to "Get a team of astronauts to the moon and back safely".
The Goddard Center's Data Evaluation Laboratory has the only known surviving piece of equipment which can read the missing tapes and was set to be closed in October 2006, causing some fear that, even if the tapes were later found, there would be no ready way to read and copy them.
However, equipment that could read the tapes was maintained.
On November 1, 2006 Cosmos Magazine reported that some NASA telemetry tapes from the Apollo project era had been found in a small marine science laboratory within the main physics building at Curtin University of Technology in Perth, Western Australia.
One of these tapes was sent to NASA for analysis.
It carried no video but did show that if any of the tapes are ever found, data could likely be read from them.

Live Tapes bonus CD.
This bonus CD is included in the November 2013 double CD edition. 
In June of 2004, Eatinger attended a meeting at the White House with Alberto Gonzales, David Addington, John Bellinger, and Scott Muller discussing what to do with tapes the CIA had made of harsh interrogations.
In 2005, tapes related to interrogations carried out at a black interrogation center in Thailand were destroyed by the CIA.
Mr. Jose Rodrieguez, former CIA clandestine branch chief, who ordered the destruction of the tapes, has said through his attorney that he based his decision on legal advice from CIA lawyers Steven Hermes and Robert Eatinger.
The information received from Hermes and Eatinger did not explicitly endorse the tape destruction, but claimed there was “no legal impediment” to disposing of them.

Question: Where are metals located on the periodic table?
About the article "Periodic table", section "Categories".

Candidate passages:
86 is the atomic number of radon.
There are 86 metals on the modern periodic table. 
Elements by periodic table can be divided up into metal, nonmetal, and metalloids (in between) based on their properties.
Everything from the left to the metalloid "stairstep" is a metal, and everything to the right is a nonmetal.
The periodic table shows most elements are metals. 
The periodic table is arranged in groups and periods, arranged in increasing order of the number of protons in the nucleus.
In general the metals are on the left and the nonmetals are on the right. 
 halogens - Group 7 on the Periodic Table and are all non-metals heat - energy transferred from one system to another by thermal interaction  
The term "post-transition metal" is generally used to describe the category of metallic elements in periods 4–6 of the periodic table, to the right of the transition elements.
As this description excludes aluminium, a period 3 metal, the post-transition elements thereby form a subset of the other metals.
The post-transition metals generally show reduced electropositivity, anionic species formation and a capacity to combine with electropositive metals to give Zintl phases.
Compounds of the group 12 metals (zinc, cadmium and mercury) are markedly non-ionic in character, both in structure and properties.
Simple cationic chemistry in the group 14 metals, tin and lead, is the exception rather than the norm.
Which elements are counted as post-transition metals depends, in periodic table terms, on where the transition metals are taken to end.
In the 1950s, most inorganic chemistry textbooks defined transition elements as finishing at group 10 (nickel, palladium and platinum), therefore excluding group 11 (copper, silver and gold), and group 12 (zinc, cadmium and mercury).
A survey of chemistry books in 2003 showed that the transition metals ended at either group 11 or group 12 with roughly equal frequency.
Question: What does a coupler attach to a bag?
About the article "Cake", section "Cake decorating".

Candidate passages:
The Riblet short-slot coupler is two waveguides side-by-side with the side-wall in common instead of the long side as in the Bethe-hole coupler.
A slot is cut in the sidewall to allow coupling.
This design is frequently used to produce a coupler. 
A star coupler is a device that takes in an input signal and splits it into several output signals.
In fiber optics, and especially in telecommunications, a star coupler is a passive optical device, used in network applications.
An optical signal introduced into any input port is distributed to all output ports.
Because of the way a passive star coupler is constructed, the number of ports is usually a power of 2; "i.e.
", two input ports and two output ports (a "two-port" coupler, customarily called a "directional coupler," or "splitter" ); four input ports and four output ports (a "four-port" coupler); eight input ports and eight output ports (an "eight-port" coupler), "etc". 
The C-AKv coupler is a newer compact Willison coupler developed by Faiveley Transport.
It is mechanical fully compatible to the SA-3 coupler and the Unicoupler and if additional buffers are mounted it can be coupled with the conventional European screw coupling as well. 
Coupler is a word used to describe any of a number of things:  A railway coupling device; * A Janney coupler;  An electronic device such as:  * An acoustic coupler for coupling electrical signals by acoustical means; * A telecommunications device known as a directional coupler; * An antenna coupler also referred to as an Antenna tuner  * A kind of laser mirror known as an output coupler;  A connector between two moving parts to relay the motion, such as a Universal joint or an Oldham coupler.
A device used on a pipe organ or harpsichord to allow a player to play multiple divisions at once, by means of "coupling" a division to another at either sub, super, or octave pitches;  A valve, specifically a tap, for controlling the release of beer out of a keg;  A short length of pipe with two female threads, see coupling (piping);  A sound artisu coupling (sound);  A quick coupler used in construction machines to allow the rapid change of buckets;  The name given to the floating link in a Four-bar linkage  Coupler is a data toll that allows coupling of data from different sources.

Chinese restaurants in the US sometimes serve small fried pastries similar to doughnut holes, served with condensed milk as a sauce.
Chinese cuisine features long, deep-fried doughnut sticks that are often quite oily, hence their name in Mandarin, "yóutiáo" (油條, lit.
oil strips.
); in Cantonese, this doughnut-style pastry is called "yàuhjagwái" (油炸鬼, "ghosts fried in oil").
These pastries are not sweet and are often served with congee, a traditional rice porridge.
Jian dui is a type of fried Chinese pastry made from glutinous rice flour.
The pastry is coated with sesame seeds on the outside and is crisp and chewy.
