Input: Read this: The first satellite, BeiDou-1A, was launched on 30 October 2000, followed by BeiDou-1B on 20 December 2000. The third satellite, BeiDou-1C (a backup satellite), was put into orbit on 25 May 2003. The successful launch of BeiDou-1C also meant the establishment of the BeiDou-1 navigation system.
Question: When was the BeiDou-1C satellite launched?

Output: 25 May 2003


QUES: For digital photo cameras ("digital still cameras"), an exposure index (EI) rating—commonly called ISO setting—is specified by the manufacturer such that the sRGB image files produced by the camera will have a lightness similar to what would be obtained with film of the same EI rating at the same exposure. The usual design is that the camera's parameters for interpreting the sensor data values into sRGB values are fixed, and a number of different EI choices are accommodated by varying the sensor's signal gain in the analog realm, prior to conversion to digital. Some camera designs provide at least some EI choices by adjusting the sensor's signal gain in the digital realm. A few camera designs also provide EI adjustment through a choice of lightness parameters for the interpretation of sensor data values into sRGB; this variation allows different tradeoffs between the range of highlights that can be captured and the amount of noise introduced into the shadow areas of the photo.

What is another name for an exposure index rating?
What is the answer?
ANS: ISO setting


QUES: Students from the Imperial University organized a widespread student protest against the eunuchs of Emperor Huan's court. Huan further alienated the bureaucracy when he initiated grandiose construction projects and hosted thousands of concubines in his harem at a time of economic crisis. Palace eunuchs imprisoned the official Li Ying (李膺) and his associates from the Imperial University on a dubious charge of treason. In 167 AD, the Grand Commandant Dou Wu (d. 168 AD) convinced his son-in-law, Emperor Huan, to release them. However the emperor permanently barred Li Ying and his associates from serving in office, marking the beginning of the Partisan Prohibitions.
On what charge was Li Ying jailed for?

ANS: treason


On 23 October 1501, at Mielnik Polish–Lithuanian union was reformed at the Union of Mielnik (Polish: unia mielnicka, unia piotrkowsko-mielnicka). It was there that the tradition of the coronation Sejm (Polish: "Sejm koronacyjny") was founded. Once again the middle nobility (middle in wealth, not in rank) attempted to reduce the power of the magnates with a law that made them impeachable before the Senate for malfeasance. However the Act of Mielno (Polish: Przywilej mielnicki) of 25 October did more to strengthen the magnate dominated Senate of Poland then the lesser nobility. The nobles were given the right to disobey the King or his representatives—in the Latin, "non praestanda oboedientia"—and to form confederations, an armed rebellion against the king or state officers if the nobles thought that the law or their legitimate privileges were being infringed.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Where was the Mielnik Polish–Lithuanian union refromed?
Ah, so.. Union of Mielnik


Question: In 2010, a genetic study was conducted on the mummified remains of baboons that were brought back as gifts from Punt by the ancient Egyptians. Led by a research team from the Egyptian Museum and the University of California, the scientists used oxygen isotope analysis to examine hairs from two baboon mummies that had been preserved in the British Museum. One of the baboons had distorted isotopic data, so the other's oxygen isotope values were compared to those of present-day baboon specimens from regions of interest. The researchers found that the mummies most closely matched modern baboon specimens in Eritrea and Ethiopia, which they suggested implied that Punt was likely a narrow region that included eastern Ethiopia and all of Eritrea.
Try to answer this question if possible: Where did researchers suggest that Punt was located?
Answer: region that included eastern Ethiopia and all of Eritrea


Problem: In the semiconductor industry, infrared light can be used to characterize materials such as thin films and periodic trench structures. By measuring the reflectance of light from the surface of a semiconductor wafer, the index of refraction (n) and the extinction Coefficient (k) can be determined via the Forouhi-Bloomer dispersion equations. The reflectance from the infrared light can also be used to determine the critical dimension, depth, and sidewall angle of high aspect ratio trench structures.
What equations are used to figure out the index of refraction and extinction Coefficient?
---
Answer:
Forouhi-Bloomer dispersion
