Hi bobbym,

The Answers, #5685 (Robert Hooke) and #5686 (Autoclave), are correct! Remarkable!

#5687. Name the  chemical element with atomic number 34. It is a nonmetal with properties that are intermediate between those of its periodic table column-adjacent chalcogen elements sulfur and tellurium. It rarely occurs in its elemental state in nature, or as pure ore compounds. It was discovered in 1817 by Jöns Jacob Berzelius, who noted the similarity of the new element to the previously known tellurium (named for the Earth). It is found in metal sulfide ores, where it partially replaces the sulfur. Commercially, it is produced as a byproduct in the refining of these ores, most often during production.

#5688. Name the chemical element  with atomic number 38. An alkaline earth metal, it is a soft silver-white or yellowish metallic element that is highly reactive chemically. The metal turns yellow when it is exposed to air. It has physical and chemical properties similar to those of its two neighbors calcium and barium. It occurs naturally in the minerals celestine, putnisite and strontianite.

Hi bobbym,

The Answer #5683 (Attenuation) is correct! Good work!

#5685. Name the scientist - A true polymath, the topics he covered during his career include comets, the motion of light, the rotation of Jupiter, gravity, human memory and the properties of air. In all of his studies and demonstrations, he adhered to the scientific method of experimentation and observation. Hooke also utilized the most up-to-date instruments in his many projects.
His most important publication was Micrographia, a 1665 volume documenting experiments he had made with a microscope. In this groundbreaking study, he coined the term "cell" while discussing the structure of cork. He also described flies, feathers and snowflakes, and correctly identified fossils as remnants of once-living things.
The 1678 publication of his Lectures of Spring shared his theory of elasticity; in what came to be known as low named after him, he stated that the force required to extend or compress a spring is proportional to the distance of that extension or compression. In an ongoing, related project, his worked for many years on the invention of a spring-regulated watch.

#5686. Name the pressure chamber used to sterilize equipment and supplies by subjecting them to high pressure saturated steam at 121 °C (249°F) for around 15-20 minutes depending on the size of the load and the contents. It was invented by Charles Chamberland in 1879, although a precursor known as the steam digester was created by Denis Papin in 1679.

Venus is the second planet from the Sun, orbiting it every 224.7 Earth days. It has no natural satellite. It is named after the Roman goddess of love and beauty. After the Moon, it is the brightest natural object in the night sky, reaching an apparent magnitude of -4.6, bright enough to cast shadows. Because Venus is an inferior planet from Earth, it never appears to venture far from the Sun: its elongation reaches a maximum of 47.8°.

Venus is a terrestrial planet and is sometimes called Earth's "sister planet" because of their similar size, mass, proximity to the Sun and bulk composition. It is radically different from Earth in other respects. It has the densest atmosphere of the four terrestrial planets, consisting of more than 96% carbon dioxide. The atmospheric pressure at the planet's surface is 92 times that of Earth's. With a mean surface temperature of 735 K (462 °C; 863 °F), Venus is by far the hottest planet in the Solar System, even though Mercury is closer to the Sun. Venus is shrouded by an opaque layer of highly reflective clouds of sulfuric acid, preventing its surface from being seen from space in visible light. It may have had oceans in the past, but these would have vaporized as the temperature rose due to a runaway greenhouse effect. The water has most probably photodissociated, and, because of the lack of a planetary magnetic field, the free hydrogen has been swept into interplanetary space by the solar wind. Venus's surface is a dry desertscape interspersed with slab-like rocks and periodically refreshed by volcanism.

17. The Shannon number, named after Claude Shannon, is an estimated lower bound on the game-tree complexity of chess of

, based on about
initial moves for White and Black and a typical game lasting about 40 pairs of moves. Shannon calculated it as an aside in his 1950 paper "Programming a Computer for Playing Chess". (This influential paper introduced the field of computer chess.)

Shannon also estimated the number of possible positions, "of the general order of

, or roughly
". This includes some illegal positions (e.g., pawns on the first rank, both kings in check) and excludes legal positions following captures and promotions. Taking these into account, Victor Allis calculated an upper bound of
for the number of positions, and estimated the true number to be about
. Recent results improve that estimate, by proving an upper bound of only
, which is less than
and showing an upper bound
in the absence of promotions. Mathematician James Grime estimates that there are
possible "sensible" games.

Allis also estimated the game-tree complexity to be at least

, "based on an average branching factor of 35 and an average game length of 80". As a comparison, the number of atoms in the observable universe, to which it is often compared, is estimated to be between

Hi bobbym,

The Answer #5682 is correct! Excellent!

#5683.  Name the general term (Physics) that refers to any reduction in the strength of a signal. It occurs with any type of signal, whether digital or analog. Sometimes called loss, it is a natural consequence of signal transmission over long distances. In electrical engineering and telecommunications, it affects the propagation of waves and signals in electrical circuits, in optical fibers, and in air (radio waves).

#5684.  Name the physical phenomenon in which the filling of an inner-shell vacancy of an atom is accompanied by the emission of an electron from the same atom. When a core electron is removed, leaving a vacancy, an electron from a higher energy level may fall into the vacancy, resulting in a release of energy. Although most of the time this energy is released in the form of an emitted photon, the energy can also be transferred to another electron, which is ejected from the atom.

The Boltzmann constant

or k, named after Ludwig Boltzmann, is a physical constant relating energy at the individual particle level with temperature. It is the gas constant R divided by the Avogadro constant

The Boltzmann constant has the dimension energy divided by temperature, the same as entropy. The accepted value in SI units is
Boltzmann's constant, k, is a bridge between macroscopic and microscopic physics. Macroscopically, the ideal gas law states that, for an ideal gas, the product of pressure p and volume V is proportional to the product of amount of substance n (in moles) and absolute temperature T:

where R is the gas constant
. Introducing the Boltzmann constant transforms the ideal gas law into an alternative form:
where N is the number of molecules of gas. For n = 1 mol, N is equal to the number of particles in one mole (Avogadro's number).

Given a thermodynamic system at an absolute temperature T, the average thermal energy carried by each microscopic degree of freedom in the system is on the order of magnitude of kT/2 (i.e., about

, or 0.013 eV, at room temperature).

Hi bobbym,

The Answer #1933 is perfect! Magnificent!

#1934. Name the disease (abbreviation) - EVD or EHF - Signs and symptoms typically start between two days and three weeks after contracting the virus with a fever, sore throat, muscular pain, and headaches. Then, vomiting, diarrhea and rash usually follow, along with decreased function of the liver and kidneys. At this time some people begin to bleed both internally and externally. The disease has a high risk of death, killing between 25 and 90 percent of those infected, with an average of about 50 percent. This is often due to low blood pressure from fluid loss, and typically follows six to sixteen days after symptoms appear.
