Henry Cavendish A natural philosopher, the greatest experimental and theoretical English chemist and physicist of his age, Henry Cavendish (10 Oct. 1731 – 24 Feb. 1810) was distinguished for great accuracy and precision in researches into the composition of atmospheric air, the properties of different gases, the synthesis of water, the law governing electrical attraction and repulsion, and calculations of the density (and hence the weight) of the Earth. Early Life: Cavendish attended Cambridge University from 1749 to 1753, but left without a degree. He engrossed himself in scientific studies but did not bother to publish a number of his important discoveries as Cavendish was sociable only with his scientific friends. Even the only existing portrait of him was sketched secretly. Contributions and Achievements: He was the first to recognize hydrogen gas as a distinct substance for which he calculated their densities as well as the densities of several other gases.
World War I Centenary: 100 Legacies of the Great War World War I changed everything. From new countries to literature, from tanks to treaties and from flamethrowers to fashion, the conflict is still writ large on our lives 100 years on. It gave birth to violent dictators and their ideologies but extended the electoral franchise to millions. It ushered in the era of mechanised warfare whilst laying the foundations for modern medicine. Empires crumbled, borders were redrawn, art movements flowered and women won the vote (even if you still had to be over 30 in some countries). After millions of men gave their lives on the battlefields of Europe, it was doubly tragic that a deadly influenza would claim up to 50 million more deaths in the conflict’s immediate aftermath. Wall Street Journal editors from around the world have selected 100 legacies that still shape our lives today.

Galaxy Flashcards and Lesson If your students can figure something out by themselves, let them. Too often, teachers give a lecture and take all the fun out of the process of discovery. Teaching about Hubble's classification system for galaxies is a good example. Instead of giving the Galaxy Lecture or the Worksheet about galaxies, do this activity instead: 1. Give each small group a set of cards with photos of the different types of galaxies. By the end of this lesson, your students show be able to identify the type of Galaxy when given a picture of a galaxy. NOTE: Email Marcia for a Dropbox download of my complete Galaxies Lesson!

History Tells Us What Will Happen Next With Brexit And Trump | The Huffington Post Note: this essay contains a lot of links out, which are underlined. Consider them further reading or me backing up my opinions. It seems we’re entering another of those stupid seasons humans impose on themselves at fairly regular intervals. My background is archaeology, so also history and anthropology. So zooming out, we humans have a habit of going into phases of mass destruction, generally self-imposed to some extent or another. [Trump is] a charismatic narcissist who feeds on the crowd to become ever stronger, creating a cult around himself. But a defining feature of humans is their resilience. By targeting frail people of all ages, and killing them by the hundreds of thousands within an extremely short period of time, the Black Death might have represented a strong force of natural selection and removed the weakest individuals on a very broad scale within Europe,” ...In addition, the Black Death significantly changed the social structure of some European regions. 1. 2. 3.
