Albert Einstein
Albert Einstein (14 March 187918 April 1955) was a German-born theoretical physicist who is best known for developing the theory of relativity. Einstein also made important contributions to quantum mechanics. His mass–energy equivalence formula , which arises from special relativity, has been called "the world's most famous equation". He received the 1921 Nobel Prize in Physics for . Born in the German Empire, Einstein moved to Switzerland in 1895, forsaking his German citizenship (as a subject of the Kingdom of Württemberg) the following year. In 1897, at the age of seventeen, he enrolled in the mathematics and physics teaching diploma program at the Swiss ETH Zurich, federal polytechnic school in Zurich, graduating in 1900. He acquired Swiss citizenship a year later, which he kept for the rest of his life, and afterwards secured a permanent position at the Swiss Patent Office in Bern. In 1905, he submitted a successful PhD dissertation to the University of Zurich. In 19 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emission Lines
A spectral line is a weaker or stronger region in an otherwise uniform and continuous spectrum. It may result from emission or absorption of light in a narrow frequency range, compared with the nearby frequencies. Spectral lines are often used to identify atoms and molecules. These "fingerprints" can be compared to the previously collected ones of atoms and molecules, and are thus used to identify the atomic and molecular components of stars and planets, which would otherwise be impossible. Types of line spectra Spectral lines are the result of interaction between a quantum system (usually atoms, but sometimes molecules or atomic nuclei) and a single photon. When a photon has about the right amount of energy (which is connected to its frequency) to allow a change in the energy state of the system (in the case of an atom this is usually an electron changing orbitals), the photon is absorbed. Then the energy will be spontaneously re-emitted, either as one photon at the same f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ultraviolet
Ultraviolet radiation, also known as simply UV, is electromagnetic radiation of wavelengths of 10–400 nanometers, shorter than that of visible light, but longer than X-rays. UV radiation is present in sunlight and constitutes about 10% of the total electromagnetic radiation output from the Sun. It is also produced by electric arcs, Cherenkov radiation, and specialized lights, such as mercury-vapor lamps, tanning lamps, and black lights. The photons of ultraviolet have greater energy than those of visible light, from about 3.1 to 12 electron volts, around the minimum energy required to ionize atoms. Although long-wavelength ultraviolet is not considered an ionizing radiation because its photons lack sufficient energy, it can induce chemical reactions and cause many substances to glow or fluoresce. Many practical applications, including chemical and biological effects, are derived from the way that UV radiation can interact with organic molecules. The ...

Lyman Series
In physics and chemistry, the Lyman series is a hydrogen spectral series of transitions and resulting ultraviolet emission lines of the hydrogen atom as an electron goes from ''n'' ≥ 2 to ''n'' = 1 (where ''n'' is the principal quantum number), the lowest energy level of the electron (groundstate). The transitions are named sequentially by Greek letters: from ''n'' = 2 to ''n'' = 1 is called Lyman-alpha, 3 to 1 is Lyman-beta, 4 to 1 is Lyman-gamma, and so on. The series is named after its discoverer, Theodore Lyman. The greater the difference in the principal quantum numbers, the higher the energy of the electromagnetic emission. History The first line in the spectrum of the Lyman series was discovered in 1906 by physicist Theodore Lyman IV, who was studying the ultraviolet spectrum of electrically excited hydrogen gas. The rest of the lines of the spectrum (all in the ultraviolet) were discovered by Lyman from 1906-1914. The spectrum of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Lawrence Bragg
Sir William Lawrence Bragg (31 March 1890 – 1 July 1971) was an Australian-born British physicist who shared the 1915 Nobel Prize in Physics with his father William Henry Bragg "for their services in the analysis of crystal structure by means of X-rays", an important step in the development of X-ray crystallography. As of 2024, he is the youngest ever Nobel laureate in physics, or in any science category, having received the award at the age of 25. Bragg was the director of the Cavendish Laboratory, Cambridge, when James D. Watson and Francis Crick reported the discovery of the structure of DNA in February 1953. Education and early life Bragg was born in Adelaide, South Australia to William Henry Bragg (1862–1942), Elder Professor of Mathematics and Physics at the University of Adelaide, and Gwendoline (1869–1929), daughter of Charles Todd, government astronomer of South Australia. In 1900, Bragg was a student at Queen's School, North Adelaide, followed by fiv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Henry Bragg
Sir William Henry Bragg (2 July 1862 – 12 March 1942) was an English physicist and X-ray crystallographer who uniquelyThis is still a unique accomplishment, because no other parent-child combination has yet shared a Nobel Prize (in any field). In several cases, a parent has won a Nobel Prize, and then years later, the child has won the Nobel Prize for separate research. An example of this is with Marie Curie and her daughter Irène Joliot-Curie, who are the only mother-daughter pair. Several father-son pairs have won two separate Nobel Prizes. shared a Nobel Prize with his son Lawrence Bragg – the 1915 Nobel Prize in Physics: "for their services in the analysis of crystal structure by means of X-rays". Biography Early years Bragg was born at Westward, near Wigton, Cumberland, England, the son of Robert John Bragg, a merchant marine officer and farmer, and his wife Mary née Wood, a clergyman's daughter. When Bragg was seven years old, his mother died, and he was rais ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Nobel Laureates In Physics
The Nobel Prize in Physics () is awarded annually by the Royal Swedish Academy of Sciences to scientists in the various fields of physics. It is one of the five Nobel Prizes established by the 1895 will and testament, will of Alfred Nobel (who died in 1896), awarded for outstanding contributions in physics. As dictated by Nobel's will, the award is administered by the Nobel Foundation and awarded by the Royal Swedish Academy of Sciences. The award is presented in Stockholm at an annual ceremony on 10 December, the anniversary of Nobel's death. Each recipient receives a medal, a diploma and a monetary award prize that has varied throughout the years. Statistics The Nobel Prize in Physics has been awarded to 226 individuals as of 2024. The first prize in physics was awarded in 1901 to Wilhelm Röntgen, Wilhelm Conrad Röntgen, of Germany, who received 150,782 Swedish krona, SEK. John Bardeen is the only laureate to win the prize twice—in 1956 and 1972. Lawrence Bragg, Willi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Auschwitz Concentration Camp
Auschwitz, or Oświęcim, was a complex of over 40 Nazi concentration camps, concentration and extermination camps operated by Nazi Germany in Polish areas annexed by Nazi Germany, occupied Poland (in a portion annexed into Germany in 1939) during World War II and the Holocaust. It consisted of #Auschwitz I, Auschwitz I, the main camp (''Stammlager'') in Oświęcim; #Auschwitz II-Birkenau, Auschwitz II-Birkenau, a concentration and extermination camp with gas chambers, #Auschwitz III, Auschwitz III-Monowitz, a Arbeitslager, labour camp for the chemical conglomerate IG Farben, and List of subcamps of Auschwitz, dozens of subcamps. The camps became a major site of the Nazis' final solution, Final Solution to the Jewish question. After Germany Causes of World War II#Invasion of Poland, initiated World War II by Invasion of Poland, invading Poland in September 1939, the ''Schutzstaffel'' (SS) converted Auschwitz I, an army barracks, into a prisoner-of-war camp.

Henri Abraham
Henri Abraham (12 July 1868–22 December 1943) was a French physicist who made important contributions to the science of radio waves. He performed some of the first measurements of the propagation velocity of radio waves, helped develop France's first triode vacuum tube, and with Eugene Bloch invented the astable multivibrator. He was murdered at Auschwitz during the Holocaust. Life Henri Abraham was born on 12 July 1868 in the 1st arrondissement of Paris. After brilliant studies at Chaptal secondary school, from 1886 to 1889 he pursued scientific graduate studies at the École normale supérieure, where he attended the lectures of physics professors Jules Violle and Marcel Brillouin, and the Faculty of Paris, where he studied physics with Gabriel Lippmann and and obtained degrees in physical sciences and in mathematical sciences. He was then appointed for one year preparer physics laboratory of the École normale supérieure, then led by Jules Violle, where he wrote his t ...

National Service
National service is a system of compulsory or voluntary government service, usually military service. Conscription is mandatory national service. The term ''national service'' comes from the United Kingdom's National Service (Armed Forces) Act 1939. The length and nature of national service depends on the country in question. In some instances, national service is compulsory, and citizens living abroad can be called back to their country of origin to complete it. In other cases, national service is voluntary. Many young people spend one or more years in such programmes. Compulsory military service typically requires all citizens to enroll for one or two years, usually at age 18 (later for university-level students). Most conscripting countries conscript only men, but Norway, Sweden, Israel, Eritrea, Malaysia, Morocco and North Korea conscript both men and women. Voluntary national service may require only three months of basic military training. The US equivalent is Selecti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
