# Napoléon Henri Reber

Napoléon Henri Reber (21 October 1807 – 24 November 1880) was a French composer.

## Life and career

Reber was born in Mulhouse, Alsace, and studied with Anton Reicha and Jean François Lesueur, wrote chamber music, and set to music works of French poets. He became professor of harmony at the Conservatoire de Paris in 1851, succeeded Fromental Halévy as professor of composition in 1862 and served as inspector of the branch conservatories. In 1853, he was elected to the chair previously occupied by George Onslow in the Académie des Beaux Arts.
His instrumental arrangement of Frédéric Chopin's Funeral March from the Funeral March Sonata was played at the graveside during Chopin's burial at Père Lachaise Cemetery in Paris on 30 October 1849.
He was made a chevalier of the Legion of Honour in 1855, and an officer in 1870. On his death, he was succeeded as a member of the Institut by Camille Saint-Saëns. Notable students include Adolphe Danhauser and Jules Massenet.
Reber died in Paris.

## Works

Among his works are a ballet, Le Diable amoureux (written jointly with François Benoist, 1840); the comic operas, Le Nuit de Noël (1848), Le Père Gaillard (1852), Les Papillotes de M. Benoist (1853), and Les Dames capitaines (1857); four symphonies, and much chamber music. He wrote a Traité d'harmonie (1862), which went through many editions.
Reber's compositions include a string quintet (his opus 1; with extra cello), two string quartets, a piano quartet (1866) and seven piano trios, and the four symphonies mentioned below:
* Symphony No. 1 in D minor
* Symphony No. 2 in C major (published by Richault of Paris)
* Symphony No. 3 in E♭ major (apparently by 1850; published by Richault of Paris)
* Symphony No. 4 in G major (apparently by 1850; published by Richault of Paris)

# Warmer (Randy VanWarmer album)

Warmer is the debut album by American singer-songwriter Randy VanWarmer.

## Release

After moving back to the United States from Cornwall, England in 1978 and settling in Woodstock, New York, twenty-three-year-old VanWarmer signed to local label Bearsville Records. A year later Warmer was released and produced by Del Newman. It was initially released on vinyl, 8-track, and cassette, and in 1995 it was released on compact disc. "Just When I Needed You Most" was written by VanWarmer when he was eighteen and still in England, and the song has been described as "a ballad of heartbreak from a man's point of view." It reached No. 4 on Billboard in 1979.

### Promotion

By December 1980, VanWarmer toured in Europe to support the release of Warmer, as well as Japan and Hong Kong.

## Reception

Professional ratings :
| Review scores ||
| Source | Rating |
| Allmusic | |
| Billboard | Mixed |
| Rolling Stone | |
A brief review in a 1979 issue of Billboard compares VanWarmer's style of singing on Warmer to that of The Bee Gees, and although the writer felt the album lacked diversity, "Just When I Needed You Most" was regarded as a good cut. According to The Guinness Encyclopedia of Popular Music, "Just When I Needed You Most" was the song VanWarmer was "best remembered for."

# Lester's theorem

In Euclidean plane geometry, Lester's theorem states that in any scalene triangle, the two Fermat points, the nine-point center, and the circumcenter lie on the same circle. The result is named after June Lester, who published it in 1997, and the circle through these points was called the Lester circle by Clark Kimberling. Lester proved the result by using the properties of complex numbers; subsequent authors have given elementary proofs, proofs using vector arithmetic, and computerized proofs. The center of the Lester circle is also a triangle center. It is the center designated as X(1116) in the Encyclopedia of Triangle Centers. Recently, Peter Moses discovered 21 other triangle centers lie on the Lester circle. The points are numbered X(15535) – X(15555) in the Encyclopedia of Triangle Centers.

## Gibert's generalization

In 2000, Bernard Gibert proposed a generalization of the Lester Theorem involving the Kiepert hyperbola of a triangle. His result can be stated as follows: Every circle with a diameter that is a chord of the Kiepert hyperbola and perpendicular to the triangle's Euler line passes through the Fermat points.

## Dao's generalizations
### Dao's first generalization

In 2014, Dao Thanh Oai extended Gibert's result to every rectangular hyperbola. The generalization is as follows: Let $H$ and $G$ lie on one branch of a rectangular hyperbola, and let $F_{+}$ and $F_{-}$ be the two points on the hyperbola that are symmetrical about its center (antipodal points), where the tangents at these points are parallel to the line $HG$. Let $K_{+}$ and $K_{-}$ be two points on the hyperbola where the tangents intersect at a point $E$ on the line $HG$. If the line $K_{+}K_{-}$ intersects $HG$ at $D$, and the perpendicular bisector of $DE$ intersects the hyperbola at $G_{+}$ and $G_{-}$, then the six points $F_{+}$, $F_{-},$ $E,$ $F,$ $G_{+}$, and $G_{-}$ lie on a circle. When the rectangular hyperbola is the Kiepert hyperbola and $F_{+}$ and $F_{-}$ are the two Fermat points, Dao's generalization becomes Gibert's generalization.

### Dao's second generalization

In 2015, Dao Thanh Oai proposed another generalization of the Lester circle, this time associated with the Neuberg cubic. It can be stated as follows: Let $P$ be a point on the Neuberg cubic, and let $P_{A}$ be the reflection of $P$ in the line $BC$, with $P_{B}$ and $P_{C}$ defined cyclically. The lines $AP_{A}$, $BP_{B}$, and $CP_{C}$ are known to be concurrent at a point denoted as $Q(P)$. The four points $X_{13}$, $X_{14}$, $P$, and $Q(P)$ lie on a circle. When $P$ is the point $X(3)$, it is known that $Q(P)=Q(X_{3})=X_{5}$, making Dao's generalization a restatement of the Lester Theorem.
