Jean-Antoine Nollet (French: [ʒɑ̃ ɑ̃twan nole]; [1] 19 November 1700 – 25 April 1770) [2] was a French clergyman and physicist who did a number of experiments with electricity and discovered osmosis. As a deacon in the Catholic Church, [2] he was also known as Abbé Nollet.
The process of osmosis over a semipermeable membrane.The blue dots represent particles driving the osmotic gradient. Osmosis (/ ɒ z ˈ m oʊ s ɪ s /, US also / ɒ s-/) [1] is the spontaneous net movement or diffusion of solvent molecules through a selectively-permeable membrane from a region of high water potential (region of lower solute concentration) to a region of low water potential ...
The potato paradox is a mathematical calculation that has a counter-intuitive result. The Universal Book of Mathematics states the problem as such: [ 1 ] Fred brings home 100 kg of potatoes, which (being purely mathematical potatoes) consist of 99% water (being purely mathematical water).
Redcliffe Nathan Salaman (12 September 1874 – 12 June 1955) was a British physician, biologist who pioneered the breeding of blight-free potatoes, Jewish nationalist, race scientist and key figure in the Anglo-Jewish community in the 20th century.
His scientific publications were numerous, and covered a wide field, but his most noteworthy work was embryological.His Recherches sur l'accroissement et la reproduction des végétaux, published in the Mémoires du museum d'histoire naturelle for 1821, procured him in that year the French Academy's prize for experimental physiology.

One control group ate an unmodified Desiree Red potato spiked with the GNA snowdrop lectin. [5] Twelve feeding experiments were conducted, ten short-term (10 days) and two long-term (110 days). [10] Before the experiment Pusztai and his team said they expected no differences between the rats fed modified potatoes and rats fed the non-modified ones.
