Who was the first scientist? It wasn't Isaac Newton. Today, it is generally acknowledged that Newton never thought of himself as a scientist. He couldn't, for the word didn't exist in was not only a scientist, but the greatest scientist who ever lived, yet (Newton his time. Newton thought of himself as a "philosopher," a word that (a)dates back to the ancient Greek thinkers and that comes from Greek words (b)meaning "lover of wisdom." There are different kinds of wisdom we might love, of course. Some philosophers are concerned chiefly with the wisdom derived from the study of the world about us and the manner of its workings. The world { c ℗ about 2 be 3 can 4 referred 5 to 6 us as "nature," from the Latin word meaning “birth." Nature, in other words, is everything that has been created or that has come into being. Philosophers who deal primarily with nature are, therefore, "natural philosophers." Newton thought of himself as a natural philosopher, and the sort of thing he studied was natural philosophy. Thus, when he wrote the book (d) he carefully described his three laws of motion and his theory of universal gravitation—the greatest scientific book ever written-he called it (in Latin) Philosophiae Naturalis Principia Mathematica, which in English is The Mathematical Principles of Natural Philosophy. The Greek word for "natural" is physikos, which in English becomes physical. Natural philosophy might also be spoken of as "physical philosophy, which can be shortened to “physics.” on. Physics As natural philosophy grew and expanded, all kinds of special studies developed. People began to speak of chemistry, of geology, of physiology, and so was whatever was left over, so it didn't suit as a general overall word for natural philosophy. Yet you needed some such short word, for natural philosophy was a seven-syllable mouthful.

What is the cause? ( 12 ) weather and drought (2) conditions in Mexico. It's not (13) chili peppers. Mustard producers in France and Canada said extreme weather caused a 50% reduction in seed production last year, ( 14 ) to a shortage of the condiment on grocery store shelves. Blistering heat, stronger storms, droughts, floods, fires and changes in rainfall (15) are also affecting the cost and availability of staples, including wheat, corn, coffee, apples, chocolate and wine. The climate crisis is increasing the intensity and ( 16 ) of extreme weather events — and it's putting food production at risk. "Almost everything we grow and ( 17 ) in the US is facing some climatic stress," said Carolyn Dimitri, nutrition and food studies professor at NYU. Wheat and other grain crops are particularly ( 18 ). In the Great Plains region, (19) most of the US's wheat is harvested, drought depressed the winter crop. Farmers are abandoning farmland used for growing winter wheat in the US-primarily in Texas and Oklahoma - at the highest rate since 2002. Meanwhile in Montana, flooding is (20) grain crops. The impact of the climate crisis on grain crops ( 21 ) beyond the US. In India, a fierce heatwave damaged the wheat crop ( 22 ) record-setting temperatures throughout the spring and summer. As Delhi hit 49°℃ in May, the government placed a ( 23 ) on wheat exports, driving up prices even further than the rise following Russia's invasion of Ukraine. Food production is a driver of the climate crisis and a (24) of it. ( 25 ) the food system will require a wide variety of actions, including increasing crop diversity, delivering climate (26) to farmers around the world, expanding conservation programs and offering growers insurance that pays out when an index such as rain or wind speed falls above or below a fixed limit. The Biden administration is supporting research into "climate-smart" agriculture, an approach to managing cropland, forest, fisheries and cattle that attempts to address the intersecting challenges of the climate crisis and food ( 27 ). In May, the UN secretary general, António Guterres, said that climate-related disasters and extreme weather were a driver of global hunger and that 1.7 billion people ( 28 ) by the climate crisis over the last decade. Experts say (29) action is taken, we can expect to see increased food prices, decreased availability and conflict over water, which will primarily affect poorer countries and low-income Americans, (30) everything from school lunches to food aid programs. © Copyright Guardian News & Media Ltd 2023 (1) sriracha (2) drought かんばつ 世界中で人気のチリソース
