Untitled[edit]

Take Ferdinand Braun, for example, the man who discovered rectification in crystals. Later he received the Nobel Prize along with Marconi. He had three great discoveries. One was crystal rectification, which is the seat of the useful properties of semiconductors. He invented the electron tube that today is the basis for that employed in television sets. And then he's the one who, after Marconi got stuck and couldn't transmit more than fifteen kilometers, noted that the circuitry Marconi was using was wrong. [1]

Braun tube[edit]

"The CRT is still called the "Braun tube" in German-speaking countries." ...doesn't sound very German? 194.70.193.179 07:37, 7 August 2006 (UTC)

Actually very few people call it "Braun'sche Röhre" here in Germany. The vast majority simply calls it "Bildröhre", similar to CRT in English.

Braun invented the phased array antenna[edit]

Braun invented the phased array antenna in 1905. This deserves to be mentioned in his biography. Braun describes the invention on page 239 of his Nobel lecture: http://www.nobelprize.org/nobel_prizes/physics/laureates/1909/braun-lecture.pdf The phased array led to the development of directional antennas, radar, smart antennas, and capacity-multiplying MIMO. The concept first investigated by Braun is also used in ultrasound, sonar, and phased array optics. Claudeb (talk) 19:41, 28 August 2013 (UTC)

Advisor[edit]

The article lists August Kundt as Braun's advisor. However, Math Genealogy claims that his advisor was Georg Hermann Quincke. Which one is correct? Maxal (talk) 21:37, 24 November 2013 (UTC)

  • I've added Quincke as a second advisor but this question needs clarification. Maxal (talk) 14:03, 27 November 2013 (UTC)

Was he really advisor to Albert Schweitzer? This sounds odd and is without reference. — Preceding unsigned comment added by 66.26.4.196 (talk) 01:39, 17 August 2015 (UTC)
