paragraph_text: In mathematics, the Torelli theorem, named after Ruggiero Torelli, is a classical result of algebraic geometry over the complex number field, stating that a non-singular projective algebraic curve (compact Riemann surface) "C" is determined by its Jacobian variety "J"("C"), when the latter is given in the form of a principally polarized abelian variety. In other words, the complex torus "J"("C"), with certain 'markings', is enough to recover "C". The same statement holds over any algebraically closed field. From more precise information on the constructed isomorphism of the curves it follows that if the canonically principally polarized Jacobian varieties of curves of genus formula_1 are "k"-isomorphic for "k" any perfect field, so are the curves.

paragraph_text: In the Salisbury rail crash of 1 July 1906, a LSWR boat train from Plymouth's Friary railway station to London Waterloo station failed to navigate a very sharp curve at the eastern end of Salisbury railway station. The curve had a maximum permitted speed of , but the express had been travelling at more than . The train was completely derailed, and smashed into a milk train and a light engine, killing 28 people.

paragraph_text: A Hilbert curve (also known as a Hilbert space-filling curve) is a continuous fractal space-filling curve first described by the German mathematician David Hilbert in 1891, as a variant of the space-filling Peano curves discovered by Giuseppe Peano in 1890.

paragraph_text: In mathematics, the Crofton formula, named after Morgan Crofton (1826–1915), is a classic result of integral geometry relating the length of a curve to the expected number of times a "random" line intersects it.

paragraph_text: The Senior Whitehead Prize of the London Mathematical Society (LMS) is now awarded in odd numbered years in memory of John Henry Constantine Whitehead, president of the LMS between 1953 and 1955. The Prize is awarded to mathematicians normally resident in the United Kingdom on 1 January of the relevant year. Selection criteria include work in, influence on or service to mathematics, or recognition of lecturing gifts in the field of mathematics. Previous recipients of top LMS prizes or medals are ineligible for nomination.

paragraph_text: In mathematics, the Edwards curves are a family of elliptic curves studied by Harold Edwards in 2007. The concept of elliptic curves over finite fields is widely used in elliptic curve cryptography. Applications of Edwards curves to cryptography were developed by Daniel J. Bernstein and Tanja Lange: they pointed out several advantages of the Edwards form in comparison to the more well known Weierstrass form.

paragraph_text: Luminous efficacy of a light source may be defined in two ways. The radiant luminous efficacy (LER) is the ratio of the visible light flux emitted (the luminous flux) to the total power radiated over all wavelengths. The source luminous efficacy (LES) is the ratio of the visible light flux emitted (the luminous flux) to the total power input to the source, such as a lamp. Visible light is measured in lumens, a unit which is defined in part by the differing sensitivity of the human eye to different wavelengths of light. Not all wavelengths of visible electromagnetic energy are equally effective at stimulating the human eye; the luminous efficacy of radiant energy (LER) is a measure of how well the distribution of energy matches the perception of the eye. The units of luminous efficacy are "lumens per watt" (lpw). The maximum LER possible is 683 lm/W for monochromatic green light at 555 nanometers wavelength, the peak sensitivity of the human eye.

paragraph_text: Richard Ernest Kronauer is the Gordon McKay Professor of Mechanical Engineering, emeritus, at Harvard University. Though experienced with research in both fluid mechanics and applied mathematics, he is primarily known for his pioneering work in mathematical biology, especially research on human circadian rhythms. Kronauer's 1982 paper "Mathematical model of the human circadian system with two interacting oscillators" outlined a new method for understanding the biological circuits that underlie daily body cycles in variables such as blood pressure or body temperature. Professor Kronauer's research also has direct implications for the causes and possible cures for many types of sleep disorders, and for this he will receive the Farrell Prize in Sleep Medicine in June 2008.

paragraph_text: HD 16417 b (also called λ Fornacis b) is an extrasolar planet located approximately 83 light years away in the constellation of Fornax, orbiting the 6th magnitude G-type main sequence star HD 16417. This planet has minimum mass only 7% that of Jupiter, making this a Neptune-mass planet. In addition to this, it orbits relatively close to the host star and suffers high temperature. It is the third planet discovered in Fornax constellation on February 23, 2009. This planet was discovered by a method called the radial velocity method.

paragraph_text: Newton built the first practical reflecting telescope and developed a sophisticated theory of colour based on the observation that a prism separates white light into the colours of the visible spectrum. His work on light was collected in his highly influential book Opticks, published in 1704. He also formulated an empirical law of cooling, made the first theoretical calculation of the speed of sound, and introduced the notion of a Newtonian fluid. In addition to his work on calculus, as a mathematician Newton contributed to the study of power series, generalised the binomial theorem to non-integer exponents, developed a method for approximating the roots of a function, and classified most of the cubic plane curves.

paragraph_text: Curtis Tracy McMullen (born May 21, 1958) is an American mathematician who is the Cabot Professor of Mathematics at Harvard University. He was awarded the Fields Medal in 1998 for his work in complex dynamics, hyperbolic geometry and Teichmüller theory.

paragraph_text: Radio waves were first predicted by mathematical work done in 1867 by Scottish mathematical physicist James Clerk Maxwell. Maxwell noticed wavelike properties of light and similarities in electrical and magnetic observations. His mathematical theory, now called Maxwell's equations, described light waves and radio waves as waves of electromagnetism that travel in space, radiated by a charged particle as it undergoes acceleration. In 1887, Heinrich Hertz demonstrated the reality of Maxwell's electromagnetic waves by experimentally generating radio waves in his laboratory, showing that they exhibited the same wave properties as light: standing waves, refraction, diffraction, and polarization. Radio waves, originally called ``Hertzian waves '', were first used for communication in the mid 1890s by Guglielmo Marconi, who developed the first practical radio transmitters and receivers.

paragraph_text: Bilkis (minor planet designation: 585 Bilkis) is a minor planet orbiting the Sun. It was discovered by German astronomer August Kopff in 1906 February and was given the Koran name for the Queen of Sheba. Photometric observations at the Palmer Divide Observatory in Colorado Springs, Colorado in 2006–7 were used to build a light curve for this object. The asteroid displayed a rotation period of 8.5742 ± 0.0005 hours and a brightness variation of 0.40 ± 0.02 in magnitude.

paragraph_text: Wien's approximation (also sometimes called Wien's law or the Wien distribution law) is a law of physics used to describe the spectrum of thermal radiation (frequently called the blackbody function). This law was first derived by Wilhelm Wien in 1896. The equation does accurately describe the short wavelength (high frequency) spectrum of thermal emission from objects, but it fails to accurately fit the experimental data for long wavelengths (low frequency) emission.

paragraph_text: The assumption that black-body radiation is thermal leads to an accurate prediction: the total amount of emitted energy goes up with the temperature according to a definite rule, the Stefan–Boltzmann law (1879–84). But it was also known that the colour of the light given off by a hot object changes with the temperature, so that "white hot" is hotter than "red hot". Nevertheless, Wilhelm Wien discovered the mathematical relationship between the peaks of the curves at different temperatures, by using the principle of adiabatic invariance. At each different temperature, the curve is moved over by Wien's displacement law (1893). Wien also proposed an approximation for the spectrum of the object, which was correct at high frequencies (short wavelength) but not at low frequencies (long wavelength). It still was not clear why the spectrum of a hot object had the form that it has (see diagram).

paragraph_text: Discovered by Michael Faraday in 1845, the Faraday effect was the first experimental evidence that light and electromagnetism are related. The theoretical basis of electromagnetic radiation (which includes visible light) was completed by James Clerk Maxwell in the 1860s and 1870s. This effect occurs in most optically transparent dielectric materials (including liquids) under the influence of magnetic fields.

paragraph_text: In mathematics, a Plücker formula, named after Julius Plücker, is one of a family of formulae, of a type first developed by Plücker in the 1830s, that relate certain numeric invariants of algebraic curves to corresponding invariants of their dual curves. The invariant called the genus, common to both the curve and its dual, is connected to the other invariants by similar formulae. These formulae, and the fact that each of the invariants must be a positive integer, place quite strict limitations on their possible values.

paragraph_text: The mechanical equivalence principle was first stated in its modern form by the German surgeon Julius Robert von Mayer in 1842. Mayer reached his conclusion on a voyage to the Dutch East Indies, where he found that his patients' blood was a deeper red because they were consuming less oxygen, and therefore less energy, to maintain their body temperature in the hotter climate. He discovered that heat and mechanical work were both forms of energy and in 1845, after improving his knowledge of physics, he published a monograph that stated a quantitative relationship between them.

paragraph_text: The Leroy P. Steele Prizes are awarded every year by the American Mathematical Society, for distinguished research work and writing in the field of mathematics. Since 1993 there has been a formal division into three categories.

paragraph_text: 750 Oskar is a minor planet orbiting the Sun that was discovered by Johann Palisa on 28 April 1913 in Vienna. Photometric observations made in 2012 at the Organ Mesa Observatory in Las Cruces, New Mexico, produced a light curve with a period of 6.2584 ± 0.0002 hours and a brightness variation of 0.21 ± 0.02 in magnitude. This is a member of the Nysa family of asteroids that share similar orbital elements.
