Who discovered the mass of an electron? How to make a Bohr model of carbon In Bohr's model of the atom, where are the electrons and protons located? Who discovered the atomic orbital? What is a Bohr diagram? How did Niels Bohr describe electrons in his atomic model?
Who discovered quantum physics? Who discovered the electron? Who was the first person to invent electricity? Who developed nanotechnology? Who was the first to propose the existence of atoms? Who developed quantum theory? Who advanced the idea of atoms in the early 1800s?
Who made the first model of a molecule? August Wilhelm von Hofmannis credited with the first physical molecular model around 1860 (Fig. 1). Did Einstein prove molecules? Einstein also in1905 mathematically proved the existence of atoms, and thus helped revolutionize all the sciences through the ...

In 1958, Anderson discovered a remark- able parallel between magnetism and superconductivity. Whereas magnets con- centrate fields, superconductors expel them, allowing them to levitate. Following John Bardeen, Leon Cooper and Robert Schrieffer's discovery that superconductivity results from electrons ...
that she wasn't just a leaf that depended on every whim of the wind,but that she was part of the universe.Through some mysterious force,Trufa understood the miracle of her molecules,atoms,protons and electrons-the enormous energy she represented and the divine plan of which she was a part...
Already in 1989, Tiina Karu published the book "Pho- tobiology of low-power laser therapy" (Routledge) and she said: "This book provides a concise review of the efforts undertaken to demonstrate or disprove the existence of photostimulation by low-power lasers. Collating the factual evidence ...
The editorial argues that by referring to conclusions like the existence of climate change or vaccine safety as “the scientific consensus”, communicators have inadvertently fanned the flames of distrust. By emphasizing agreement between scientists, the phrase “scientific consensus” leaves open the que...
The existence of the mitochondrial genome ‘aside’ the nuclear genome allows eukaryotes to possess chimeric enzyme complexes, central to the cellular bioenergetics, comprising subunits which are encoded in the two different genomes. The transfer of genetic control to the nucleus, places the ability ...
Although it is possible to trace the history of the harnessing of electrical power and identify the people responsible for various breakthroughs along the way, it is difficult to put a name to the person who first discovered electricity. Very early in human history, people would have witnessed ...
