A science magazine is a periodical publication with news, opinions, and reports about science, generally written for a non-expert audience. In contrast, a periodical publication, usually including primary research and/or reviews, that is written by scientific experts is called a "scientific journal".
The experiment consists of two brass bells, each positioned beneath a dry pile (a form of battery), the pair of piles connected in series, giving the bells opposite electric charges. The clapper is a metal sphere approximately 4 mm (3 ⁄ 16 in) in diameter suspended between the piles, which rings the bells alternately due to electrostatic ...
The report ruled out any doomsday scenario at the LHC, noting that the physical conditions and collision events which exist in the LHC, RHIC and other experiments occur naturally and routinely in the universe without hazardous consequences, [3] including ultra-high-energy cosmic rays observed to impact Earth with energies far higher than those ...
Davisson–Germer experiment; Gold foil experiments, performed by Geiger and Marsden for Rutherford which discovered the atomic nucleus; Elucidation of the structure of DNA by X-ray crystallography; Discovery of the antiproton at the Bevatron; Discovery of W and Z bosons at CERN; Discovery of the Higgs boson at the Large Hadron Collider; MINERνA
Benjamin Libet's experiment on free will shows that a readiness potential appears before the notion of doing the task enters conscious experience, sparking debate about the illusory nature of free will yet again. (1983) Vilayanur S. Ramachandran's experiment on phantom limbs with the Mirror Box throw light on the nature of 'learned paralysis ...
1021 – Ibn al-Haytham (Alhacen) pioneers the experimental scientific method and experimental physics in his Book of Optics, where he devises the first scientific experiments on optics, including the first use of the camera obscura to prove that light travels in straight lines and the first experimental proof that visual perception is caused ...
