With the rise of nuclear power after World War II, Schaeffer became a notable activist in the anti-nuclear movement, one of the main factors associated with his personal life other than his work in the field of music.
Schaeffer became an associate professor at the Paris Conservatoire from 1968 to 1980 after creating a "class of fundamental music and application to the audiovisual." He suffered from Alzheimer's disease later in his life, and died from the condition in Aix-en-Provence in 1995. He was 85 years old. He is buried in Delincourt in the very nice and green Vexin region (55 minutes from Paris) where he used to have his countryside property.
Schaeffer was thereafter remembered by many of his colleagues with the title, "Musician of Sounds".
Cabbage seedlings have a thin taproot and cordate (heart-shaped) cotyledon. The first leaves produced are ovate (egg-shaped) with a lobed petiole. Plants are 4060 cm (1624 in) tall in their first year at the mature vegetative stage, and 1.52.0 m (4.96.6 ft) tall when flowering in the second year. Heads average between 0.5 and 4 kg (1 and 8 lb), with fast-growing, earlier-maturing varieties producing smaller heads. Most cabbages have thick, alternating leaves, with margins that range from wavy or lobed to highly dissected; some varieties have a waxy bloom on the leaves. Plants have root systems that are fibrous and shallow. About 90 percent of the root mass is in the upper 2030 cm (812 in) of soil; some lateral roots can penetrate up to 2 m (6.6 ft) deep.
The inflorescence is an unbranched and indeterminate terminal raceme measuring 50100 cm (2040 in) tall, with flowers that are yellow or white. Each flower has four petals set in a perpendicular pattern, as well as four sepals, six stamens, and a superior ovary that is two-celled and contains a single stigma and style. Two of the six stamens have shorter filaments. The fruit is a silique that opens at maturity through dehiscence to reveal brown or black seeds that are small and round in shape. Self-pollination is impossible, and plants are cross-pollinated by insects. The initial leaves form a rosette shape comprising 7 to 15 leaves, each measuring 2535 cm (1014 in) by 2030 cm (812 in); after this, leaves with shorter petioles develop and heads form through the leaves cupping inward.
Many shapes, colors and leaf textures are found in various cultivated varieties of cabbage. Leaf types are generally divided between crinkled-leaf, loose-head savoys and smooth-leaf firm-head cabbages, while the color spectrum includes white and a range of greens and purples. Oblate, round and pointed shapes are found.
Cabbage has been selectively bred for head weight and morphological characteristics, frost hardiness, fast growth and storage ability. The appearance of the cabbage head has been given importance in selective breeding, with varieties being chosen for shape, color, firmness and other physical characteristics. Breeding objectives are now focused on increasing resistance to various insects and diseases and improving the nutritional content of cabbage. Scientific research into the genetic modification of B. oleracea crops, including cabbage, has included European Union and United States explorations of greater insect and herbicide resistance. Genetically modified B. oleracea crops are not currently used in commercial agriculture.
