Major everyday discoveries that were helped by luck in some way include products like vulcanized rubber, teflon, nylon, penicillin, cyanoacrylate (Super Glue), the implantable pacemaker [citation needed], the microwave oven, Scotchgard, Saran wrap, Silly Putty, Slinky, safety glass, [3] propeller, snowmaking [citation needed], stainless steel ...
Merton believed that it is multiple discoveries, rather than unique ones, that represent the common pattern in science. [4] Merton contrasted a "multiple" with a "singleton"—a discovery that has been made uniquely by a single scientist or group of scientists working together. [5] The distinction may blur as science becomes increasingly ...
For example, water is composed of two hydrogen atoms bonded to one oxygen atom: the chemical formula is H 2 O. In the case of non-stoichiometric compounds , the proportions may be reproducible with regard to their preparation, and give fixed proportions of their component elements, but proportions that are not integral [e.g., for palladium ...
Examples of fermions are electrons, neutrinos, quarks, protons, neutrons, and helium-3 nuclei. The fact that particles can be identical has important consequences in statistical mechanics, where calculations rely on probabilistic arguments, which are sensitive to whether or not the objects being studied are identical. As a result, identical ...
An example is ozone, which has the chemical formula O 3. [6] Ionic species: Atoms or molecules that have gained or lost electrons, resulting in a net electrical charge that can be either positively (cation) or negatively charged (anion). Species with an overall positive charge will be a cationic species.
The global wellness industry is now estimated at $6.3 trillion, giving companies lots of incentives to draw in consumers even if the science behind their products isn't solid — a process called ...
Robert Hooke, using a microscope, observes cells (1665).; Anton van Leeuwenhoek discovers microorganisms (1674–1676).; James Lind, publishes 'A Treatise of the Scurvy' which describes a controlled shipboard experiment using two identical populations but with only one variable, the consumption of citrus fruit (1753).
A biosimilar (also known as follow-on biologic or subsequent entry biologic) is a biologic medical product that is almost an identical copy of an original product that is manufactured by a different company. [1]
