- Rutherford model (Wikipedia)
The Rutherford model was devised by Ernest Rutherford to describe an atom. Rutherford directed the Geiger–Marsden experiment in 1909, which suggested, upon Rutherford’s 1911 analysis, that J. J. Thomson’s plum pudding model of the atom was incorrect. Rutherford’s new model for the atom, based on the experimental results, contained new features of a relatively high central charge concentrated into a very small volume in comparison to the rest of the atom and with this central volume containing most of the atom’s mass; this region would be known as the atomic nucleus. The Rutherford model was subsequently superseded by the Bohr model.
- Paprika (Wikipedia)
Paprika (US /pəˈprikə/, /pæˈprikə/; UK /ˈpæprɪkə/, /pəˈpriːkə/) is a spice made from dried and ground red peppers. It is traditionally made from Capsicum annuum varietals in the Longum group, including chili peppers. Paprika can have varying levels of heat, but the chili peppers used for hot paprika tend to be milder and have thinner flesh than those used to produce chili powder. In some languages, but not English, the word paprika also refers to the plant and the fruit from which the spice is made, as well as to peppers in the Grossum group (e.g., bell peppers).
