The year 1906 in science and technology included many events, some of which are listed below.

1 Chemistry

• Charles Barkla discovers that each element has a characteristic X-ray and that the degree of penetration of these X-rays is related to the atomic weight of the element
• Mikhail Tsvett discovers the chromatography technique for organic compound separation

2 Geology

• April 18 - The 1906 San Francisco earthquake, an est. 7.9 on the Richter scale and centered on the San Andreas fault, strikes near San Francisco, CaliforniaFor other meanings, see San Francisco (disambiguation). Bay Bridge. In the distance is fog covering the western third of the city.

The earthquakeAn earthquake is a trembling or shaking movement of the Earth's surface. Earthquakes typically result from the movement of faults, quasi-planar zones of deformation within its uppermost layers. The word earthquake is also widely used to indicate the sourc and fire destroy over 80% of the buildings in the city, and kill as many as 6,000 people.
• Richard OldhamRichard Dixon Oldham ( July 31, 1858 July 15, 1936) was a British geologist who, in 1906, argued that the Earth must have a molten interior as S waves were not able to travel through liquids nor through the Earth's interior. See also: Lehmann, Inge, seism argues that the EarthEarth also known as the Earth or Terra is the planet on which we live, the third planet outward from the Sun. It is the largest of the solar system's terrestrial planets, and the only planetary body that modern science confirms as harbouring life. The pla has a molten interior

3 Physics

• Walther NernstWalther Hermann Nernst ( June 25, 1864 November 18, 1941) was a German chemist and helped establish the modern field physical chemistry. Nernst contributed to electrochemistry, thermodynamics, solid state chemistry and photochemistry. Nernst discoveries a presents a formulation of the third law of thermodynamicsThe third law of thermodynamics was developed by Walther Nernst and is thus sometimes referred to as Nernst's theorem . This states that the entropy of a system at zero absolute temperature is a well-defined constant. This is because a system at zero temp
