On This Day
1743 – Jean-Pierre Christin developed the centigrade temperature scale.
The Celsius scale, previously known as the centigrade scale,[1][2] is a temperature scale used by the International System of Units (SI). As an SI derived unit, it is used by all countries in the world, except the United States, Myanmar, and Liberia. It is named after the Swedish astronomer Anders Celsius (1701–1744), who developed a similar temperature scale. The degree Celsius (symbol: °C) can refer to a specific temperature on the Celsius scale as well as a unit to indicate a temperature interval, a difference between two temperatures or an uncertainty. Before being renamed to honor Anders Celsius in 1948, the unit was called centigrade, from the Latin centum, which means 100, and gradus, which means steps.
Before 1954, the Celsius scale was based on 0 °C for the freezing point of water and 100 °C for the boiling point of water at 1 atm pressure following a change introduced in 1743 by Jean-Pierre Christin to reverse the Celsius thermometer scale (from water boiling at 0 degrees and ice melting at 100 degrees). This scale is widely taught in schools today.
By international agreement, since 1954 the unit “degree Celsius” and the Celsius scale are defined by absolute zero and the triple point of Vienna Standard Mean Ocean Water (VSMOW), a specially purified water. This definition also precisely relates the Celsius scale to the Kelvin scale, which defines the SI base unit of thermodynamic temperature with symbol K. Absolute zero, the lowest temperature possible, is defined as being exactly 0 K and −273.15 °C. The temperature of the triple point of water is defined as exactly 273.16 K (0.01 °C; 32.02 °F).[3] This means that a temperature difference of one degree Celsius and that of one kelvin are exactly the same.[4]

1932 – Elena Poniatowska, Mexican intellectual and journalist
Hélène Elizabeth Louise Amélie Paula Dolores Poniatowska (born May 19, 1932), known professionally as Elena Poniatowska (About this sound audio (help·info)), is a French-born Mexican journalist and author, specializing in works on social and political issues focused on those considered to be disenfranchised especially women and the poor. She was born in Paris to upper class parents, including her mother whose family fled Mexico during the Mexican Revolution. She left France for Mexico when she was ten to escape the Second World War. When she was eighteen and without a university education, she began writing for the newspaper Excélsior, doing interviews and society columns. Despite the lack of opportunity for women from the 1950s to the 1970s, she evolved to writing about social and political issues in newspapers, books in both fiction and nonfiction form. Her best known work is La noche de Tlatelolco (The night of Tlatelolco, the English translation was entitled “Massacre in Mexico”) about the repression of the 1968 student protests in Mexico City. She is considered to be “Mexico’s grande dame of letters” and is still an active writer.

Good news from tragedy. I read about a funeral home who did not charge for children’s services. No desire to profit from the loss of a child. Be interesting if any of the funeral homes will help the families with free or lower the cost of services.
