Heinrich Rudolf Hertz (/ h ɜːr t s /, HURTS; German: [ˈhaɪnʁɪç hɛʁts]; [1] [2] 22 February 1857 – 1 January 1894) was a German physicist who first conclusively proved the existence of the electromagnetic waves predicted by James Clerk Maxwell's equations of electromagnetism.
The sequence hypothesis was first formally proposed in the review "On Protein Synthesis" by Francis Crick in 1958. [1] It states that the sequence of bases in the genetic material (DNA or RNA) determines the sequence of amino acids for which that segment of nucleic acid codes, and this amino acid sequence determines the three-dimensional structure into which the protein folds.
Hertz wireless experiments (1887): Heinrich Hertz demonstrates free space electromagnetic waves, predicted by Maxwell's equations, with a simple dipole antenna and spark gap oscillator. Thomson's experiments with cathode rays (1897): J. J. Thomson's cathode ray tube experiments (discovers the electron and its negative charge).
The original work in contact mechanics dates back to 1881 with the publication of the paper "On the contact of elastic solids" [3] "Über die Berührung fester elastischer Körper" by Heinrich Hertz. Hertz attempted to understand how the optical properties of multiple, stacked lenses might change with the force holding them together. Hertzian ...

German physicist Heinrich Hertz in 1887 built the first experimental spark gap transmitters during his historic experiments to demonstrate the existence of electromagnetic waves predicted by James Clerk Maxwell in 1864, in which he discovered radio waves, [23] [24]: p.3-4 [25] [17]: p.19, 260, 331–332 which were called "Hertzian waves" until ...
The Franck–Hertz experiment was the first electrical measurement to clearly show the quantum nature of atoms. It was presented on April 24, 1914, to the German Physical Society in a paper by James Franck and Gustav Hertz. [1] [2] Franck and Hertz had designed a vacuum tube for studying energetic electrons that flew through a thin vapor of ...
The DNA template labeled at the 3' or 5' end, depending on the location of the binding site(s). Labels that can be used are: radioactivity and fluorescence.Radioactivity has been traditionally used to label DNA fragments for footprinting analysis, as the method was originally developed from the Maxam-Gilbert chemical sequencing technique.
