With the advent of mass-produced binary components for computers, ternary computers have diminished in significance. However, Donald Knuth argues that they will be brought back into development in the future to take advantage of ternary logic's elegance and efficiency. One possible way this could happen is by combining an optical computer with the ternary logic system. A ternary computer using fiber optics could use dark as 0 and two orthogonal polarizations of light as 1 and −1. IBM also reports infrequently on ternary computing topics (in its papers), but it is not actively engaged in it.The Josephson junction has been proposed as a balanced ternary memory cell, using circulating superconducting currents, either clockwise, counterclockwise, or off.  "The advantages of the proposed memory circuit are capability of high speed computation, low power consumption and very simple construction with fewer elements due to the ternary operation."In 2009, a quantum computer was proposed which uses a quantum ternary state, a qutrit, rather than the typical qubit. When the number of basic states of quantum element is d, it is called qudit.

Although the Greeks and Romans did much to advance water clock technology, they still continued to use shadow clocks. The mathematician and astronomer Theodosius of Bithynia, for example, is said to have invented a universal sundial that was accurate anywhere on Earth, though little is known about it. Others wrote of the sundial in the mathematics and literature of the period. Marcus Vitruvius Pollio, the Roman author of De Architectura, wrote on the mathematics of gnomons, or sundial blades. During the reign of Emperor Augustus, the Romans constructed the largest sundial ever built, the Solarium Augusti. Its gnomon was an obelisk from Heliopolis. Similarly, the obelisk from Campus Martius was used as the gnomon for Augustus's zodiacal sundial. Pliny the Elder records that the first sundial in Rome arrived in 264 BC, looted from Catania, Sicily; according to him, it gave the incorrect time until the markings and angle appropriate for Rome's latitude were used—a century later.

Question: What was Theodosius of Bithynia known for being?
Answer: mathematician and astronomer
Egyptian shadow clocks divided daytime into 12 parts with each part further divided into more precise parts. One type of shadow clock consisted of a long stem with five variable marks and an elevated crossbar which cast a shadow over those marks. It was positioned eastward in the morning so that the rising sun cast a shadow over the marks, and was turned west at noon to catch the afternoon shadows. Obelisks functioned in much the same manner: the shadow cast on the markers around it allowed the Egyptians to calculate the time. The obelisk also indicated whether it was morning or afternoon, as well as the summer and winter solstices. A third shadow clock, developed c. 1500 BC, was similar in shape to a bent T-square. It measured the passage of time by the shadow cast by its crossbar on a non-linear rule. The T was oriented eastward in the mornings, and turned around at noon, so that it could cast its shadow in the opposite direction.Although accurate, shadow clocks relied on the sun, and so were useless at night and in cloudy weather. The Egyptians therefore developed a number of alternative timekeeping instruments, including water clocks, and a system for tracking star movements. The oldest description of a water clock is from the tomb inscription of the 16th-century BC Egyptian court official Amenemhet, identifying him as its inventor. There were several types of water clocks, some more elaborate than others. One type consisted of a bowl with small holes in its bottom, which was floated on water and allowed to fill at a near-constant rate; markings on the side of the bowl indicated elapsed time, as the surface of the water reached them. The oldest-known waterclock was found in the tomb of pharaoh Amenhotep I (1525–1504 BC), suggesting that they were first used in ancient Egypt. Another Egyptian method of determining the time during the night was using plumb-lines called merkhets. In use since at least 600 BC, two of these instruments were aligned with Polaris, the north pole star, to create a north–south meridian. The time was accurately measured by observing certain stars as they crossed the line created with the merkhets.

Question: What did the obelisk indicate?
Answer: whether it was morning or afternoon
In Greek tradition, clepsydrae were used in court; later, the Romans adopted this practice, as well. There are several mentions of this in historical records and literature of the era; for example, in Theaetetus, Plato says that "Those men, on the other hand, always speak in haste, for the flowing water urges them on". Another mention occurs in Lucius Apuleius' The Golden Ass: "The Clerk of the Court began bawling again, this time summoning the chief witness for the prosecution to appear. Up stepped an old man, whom I did not know. He was invited to speak for as long as there was water in the clock; this was a hollow globe into which water was poured through a funnel in the neck, and from which it gradually escaped through fine perforations at the base". The clock in Apuleius's account was one of several types of water clock used. Another consisted of a bowl with a hole in its centre, which was floated on water. Time was kept by observing how long the bowl took to fill with water.Although clepsydrae were more useful than sundials—they could be used indoors, during the night, and also when the sky was cloudy—they were not as accurate; the Greeks, therefore, sought a way to improve their water clocks. Although still not as accurate as sundials, Greek water clocks became more accurate around 325 BC, and they were adapted to have a face with an hour hand, making the reading of the clock more precise and convenient. One of the more common problems in most types of clepsydrae was caused by water pressure: when the container holding the water was full, the increased pressure caused the water to flow more rapidly. This problem was addressed by Greek and Roman horologists beginning in 100 BC, and improvements continued to be made in the following centuries. To counteract the increased water flow, the clock's water containers—usually bowls or jugs—were given a conical shape; positioned with the wide end up, a greater amount of water had to flow out in order to drop the same distance as when the water was lower in the cone. Along with this improvement, clocks were constructed more elegantly in this period, with hours marked by gongs, doors opening to miniature figurines, bells, or moving mechanisms. There were some remaining problems, however, which were never solved, such as the effect of temperature. Water flows more slowly when cold, or may even freeze.Between 270 BC and AD 500, Hellenistic (Ctesibius, Hero of Alexandria, Archimedes) and Roman horologists and astronomers began developing more elaborate mechanized water clocks. The added complexity was aimed at regulating the flow and at providing fancier displays of the passage of time. For example, some water clocks rang bells and gongs, while others opened doors and windows to show figurines of people, or moved pointers, and dials. Some even displayed astrological models of the universe.

Question: Where were clepsydrae used?
Answer: in court

Question: What is a result of the increased pressure?
Answer: water to flow more rapidly
Other ancient timekeeping devices include the candle clock, used in ancient China, ancient Japan, England and Mesopotamia; the timestick, widely used in India and Tibet, as well as some parts of Europe; and the hourglass, which functioned similarly to a water clock.  The sundial, another early clock, relies on shadows to provide a good estimate of the hour on a sunny day.  It is not so useful in cloudy weather or at night and requires recalibration as the seasons change (if the gnomon was not aligned with the Earth's axis).

Question: what was used to determine time in the ancient days?
Answer: candle clock
In the early months of 1821, the Greeks declared their independence but did not achieve it until 1829. The Great Powers first shared the same view concerning the necessity of preserving the status quo of the Ottoman Empire, but soon changed their stance. Scores of non-Greeks volunteered to fight for the cause, including Lord Byron.

Question: When did greek achieve its ultimate independence?
Answer: 1829.
The history of Greece encompasses the history of the territory of the modern nation state of Greece as well as that of the Greek people and the areas they inhabited and ruled historically. The scope of Greek habitation and rule has varied throughout the ages and as a result the history of Greece is similarly elastic in what it includes. Generally, the history of Greece is divided into the following periods:

Question: what area is inhabited and ruled by the Greek people?
Answer: Greece

After the war, Leona Marshall returned to the University of Chicago, where she became a fellow at Fermi's Institute for Nuclear Studies. Working with the Chicago Pile 3 heavy water reactor, she found a way to 100 percent spin polarize neutron beams, and determined the refractive index of neutrons for various materials. Her second child, John Marshall III, was born in 1949. She became an assistant professor in 1953.After Fermi died in 1954, the Marshalls separated. John Marshall returned to the Los Alamos Laboratory, while Leona, now effectively a single mother, became a fellow at the Institute for Advanced Study in Princeton, New Jersey in 1957. The following year she became a fellow at the Brookhaven National Laboratory, at a time when the focus of research in physics was shifting away from the nucleus and towards elementary particles. In 1960, she joined New York University as an associate professor of physics. She became a professor in 1962.Three years later, she became a professor at the University of Colorado, researching high-energy physics, astrophysics and cosmology. She then became a staff member at RAND Corporation, where she worked until 1976. In 1966, she divorced John Marshall, and married Willard Libby, who had won the Nobel prize in 1960. She later joined him at UCLA, where she became a visiting professor of environmental studies, engineering, engineering archaeology, mechanical aerospace  and nuclear engineering in 1973.Now known as Leona Marshall Libby, she became interested in ecological and environmental issues, and she devised a method of using the isotope ratios of Oxygen-18 to Oxygen-16, Carbon-13 to Carbon-12, and Deuterium to Hydrogen in tree rings to study changes in temperature and rainfall patterns hundreds of years before records were kept, opening the door to the study of climate change.Like Willard Libby, she was a strong advocate of food irradiation as a means of killing off harmful bacteria, and advocated that legal and regulatory restrictions on its use be relaxed. She proposed that, instead of it being sprayed with malathion, fruit affected by the Mediterranean fruit fly could be treated with gamma rays.She was a prolific author, publishing over 200 scientific papers.  While at RAND she wrote a paper on Creation of an Atmosphere for the Moon (1969). Her works include the autobiographical The Uranium People (1979), a history of early atomic research. After Libby died in 1980, she edited his papers with Rainer Berger, and published The Life Work of Nobel Laureate Willard Libby (1982). Her last paper, on quasi-stellar objects, appeared in 1984.She died at St. John's Medical Center in Santa Monica, California, on November 10, 1986, from an anesthesia-induced stroke. She was survived by her sons Peter and John, and four grandchildren. She also had two stepdaughters, Janet Eva Libby and Susan Charlotte Libby from her second marriage.

Laura Fermi remembered Woods as "a tall young girl built like an athlete, who could do a man's job and do it well. She was the only woman physicist in Enrico's group. At that time, her mother, who was also endowed with inexhaustible energy, was running a small farm near Chicago almost by herself. To relieve Mrs. Woods of some work, Leona divided her time between atoms and potatoes."Like many scientists working on the project, Woods affected a casual attitude towards the danger posed by radiation. After a morning with Willard Libby soldering a canister containing a mixture of radium salt and beryllium metal, Woods absorbed about 200 roentgens, and her white blood cell count halved. The doctors gave her a lecture on how a woman has only a fixed number of egg cells, a proposition that Woods was skeptical of. She considered that the important thing was that the solder was done correctly. When the team moved to their new home at Argonne, Woods had a dormitory all to herself.Woods married John Marshall in July 1943. Soon after, she fell pregnant. While she told Enrico Fermi, they agreed not to let Walter Zinn know, for fear that he would insist that she leave the reactor building. She covered up her pregnant belly with her baggy denim work clothes. She rode to work each day on an unheated Army bus, "arriving each morning barely in time to vomit before starting the day's work." The child, a boy called Peter, was born in 1944. She returned to work a few days later.A team from Argonne was on hand for powering up the first reactor at the Hanford Site, where large reactors would produce plutonium for bombs. They watched the reactor in shifts, with John Marshall and others on the day shift, Enrico Fermi and Leona Marshall on the night shift, ending at midnight, and Don Hughes and John Wheeler on the swing shift. While the Marshalls were babysitting the reactor in Hanford, they left Peter with Leona's mother.The reactor was powered up successfully, but after a few hours the power level dropped and the reactor shut down. Leona speculated that a water leak was the problem, rather than a radioactive poison. However, during the night the operators were able to power the reactor up again only to have it once more die away. The timings now pointed to a radioactive poison. After working through the numbers with slide rules and hand calculators, they determined the neutron cross section of the poison, which turned out to be xenon-135. Fortunately, the DuPont engineers had equipped the reactor with 50 per cent more fuel tubes than the physicists had called for, and by loading them up, they managed to get the reactor started.Asked many years later about how she felt about her involvement in the Manhattan Project, she said:

Question: What was the occupation of Mrs. Wood's mother?
Answer: running a small farm
Leona Harriet Woods (August 9, 1919 – November 10, 1986), later known as Leona Woods Marshall and Leona Woods Marshall Libby, was an American physicist who helped build the first nuclear reactor and the first atomic bomb.

Question: When was Leona Woods born?
Answer: August 9, 1919
In astronomy, those elements with higher atomic numbers than helium are termed "metals". The metallicity of Vega's photosphere is only about 32% of the abundance of heavy elements in the Sun's atmosphere. (Compare this, for example, to a threefold metallicity abundance in the similar star Sirius as compared to the Sun.) For comparison, the Sun has an abundance of elements heavier than helium of about ZSol = 0.0172 ± 0.002. Thus, in terms of abundances, only about 0.54% of Vega consists of elements heavier than helium.

Question: What is the name for elements that have a higher atomic number than helium?
Answer: metals

Question: How many elements are heavier than helium in Vega?
Answer: 0.54%
The unusually low metallicity of Vega makes it a weak Lambda Boötis star. However, the reason for the existence of such chemically peculiar, spectral class A0-F0 stars remains unclear. One possibility is that the chemical peculiarity may be the result of diffusion or mass loss, although stellar models show that this would normally only occur near the end of a star's hydrogen-burning lifespan. Another possibility is that the star formed from an interstellar medium of gas and dust that was unusually metal-poor.The observed helium to hydrogen ratio in Vega is 0.030 ± 0.005, which is about 40% lower than the Sun. This may be caused by the disappearance of a helium convection zone near the surface. Energy transfer is instead performed by the radiative process, which may be causing an abundance anomaly through diffusion.

Question: Vega is what kind of Manda Bootis star?
Answer: weak
Vega has been extensively studied by astronomers, leading it to be termed “arguably the next most important star in the sky after the Sun”. Vega was the northern pole star around 12,000 BC and will be so again around the year 13,727, when the declination will be +86°14'. Vega was the first star other than the Sun to be photographed and the first to have its spectrum recorded. It was one of the first stars whose distance was estimated through parallax measurements. Vega has functioned as the baseline for calibrating the photometric brightness scale and was one of the stars used to define the zero point for the UBV photometric system.

Question: What is considered a significant star in the sky?
Answer: Vega
Vega is the brightest star in the northern constellation of Lyra. It has the Bayer designation α Lyrae, which is Latinised to Alpha Lyrae and abbreviated Alpha Lyr or α Lyr. This star is relatively close at only 25 light-years from the Sun, and, together with Arcturus and Sirius, one of the most luminous stars in the Sun's neighborhood. It is the fifth-brightest star in the night sky, and the second-brightest star in the northern celestial hemisphere, after Arcturus.

Question: The fifth-brightest star in the sky exists at what distance from the Sun?
Answer: 25 light-years
Organ transplantation in China has taken place since the 1960s, and is one of the largest organ transplant programmes in the world, peaking at over 13,000 transplants a year in 2004. China is also involved in innovative transplant surgery such as face transplantation including bone.Involuntary organ harvesting is illegal under Chinese law; though, under a 1984 regulation, it became legal to remove organs from executed criminals with the prior consent of the criminal or permission of relatives. Growing concerns about possible ethical abuses arising from coerced consent and corruption led medical groups and human rights organizations, by the 1990s, to start condemning the practice. These concerns resurfaced in 2001, when a Chinese asylum-seeking doctor testified that he had taken part in organ extraction operations.In 2006, allegations emerged that a large number of Falun Gong practitioners had been killed to supply China's organ transplant industry. An initial investigation stated "the source of 41,500 transplants for the six year period 2000 to 2005 is unexplained" and concluded that "there has been and continues today to be large scale organ seizures from unwilling Falun Gong practitioners".In December 2005, China's Deputy Health Minister acknowledged that the practice of removing organs from executed prisoners for transplants was widespread. In 2007, China issued regulations banning the commercial trading of organs, and the Chinese Medical Association agreed that the organs of prisoners should not be used for transplantation, except for members of the immediate family of the deceased. In 2008, a liver-transplant registry system was established in Shanghai, along with a nationwide proposal to incorporate information on individual driving permits for those wishing to donate their organs.Despite these initiatives, China Daily reported in August 2009 that approximately 65% of transplanted organs still came from death row prisoners.  The condemned prisoners have been described as "not a proper source for organ transplants" by Vice-Health Minister Huang Jiefu, and in March 2010 he announced the trial of China's first organ donation program starting after death, jointly run by the Red Cross Society and the Ministry of Health, in 10 pilot regions. In 2013, Huang Jiefu altered his position on utilizing prisoners' organs, stating that death row prisoners should be allowed to donate organs and should be integrated into the new computer-based organ allocation system.

Question: when did organ transplantation begin?
Answer: 1960s
