Through the Looking-Glass, and What Alice Found There (1871) is a novel by Lewis Carroll, the sequel to Alice's Adventures in Wonderland (1865). Set six months later than the earlier book, Alice again enters a fantastical world, this time by climbing through a mirror into the world that she can see beyond it. Upon leaving the house (where it had been a cold, snowy night), she enters a sunny spring garden where the flowers can speak; they perceive Alice as being a flower that can move about. John Tenniel (February 28, 1820 - February 25, 1914) was an English illustrator, graphic humorist, and political cartoonist prominent in the second half of the 19th century.

Standard periodic table. The periodic table shows the chemical elements ordered by atomic number (number of protons in the nucleus), but arranged in rows (periods) so that elements with similar chemistry occur in the same vertical column (group). The standard periodic table has 118 elements arranged in 18 groups and 7 periods. Each element is represented by its chemical symbol. Above each symbol is the element's atomic number, and below it is the atomic weight, and the element's name. The lathanoids and actinoids are expanded at bottom. This periodic table uses the standard names and data published by IUPAC (the International Union of Pure and Applied Chemistry) in 2005. Elements 112 to 118 have yet to be fully authenticated and have tem...

This illustration accompanies a tract on avoiding the plague, an often deadly disease which first devastated Europe in 1348 and continued in the form of epidemics until the 1700s. The image shows a plague victim who, judging from his face, is in bad shape but, judging from the setting, rather privileged. A physician is visiting the patient at home. He is taking the pulse, while holding to his nose a sponge soaked with wine vinegar, which was the prime prophylactic against the plague's "miasma," that is, spoiled and infectious air.

Aristotle (384 - 322 BC) was an ancient Greek philosopher, polymath, student of Plato and teacher of Alexander the Great. His writings cover many subjects, including physics, metaphysics, poetry, theater, music, logic, rhetoric, linguistics, politics, government, ethics, biology, and zoology. Together with Plato and Socrates, Aristotle is one of the most important founding figures in Western philosophy. His writings were the first to create a comprehensive system of Western philosophy, encompassing morality and aesthetics, logic and science, politics and metaphysics. His views on physical science profoundly shaped medieval scholarship. Their influence extended into the Renaissance and were not replaced systematically until the Enlightenm...

Enrico Fermi (September 29, 1901 - November 28, 1954) was an an Italian-born, naturalized American physicist particularly known for his work on the development of the first nuclear reactor, Chicago Pile-1, and for his contributions to the development of quantum theory, nuclear and particle physics, and statistical mechanics. He was awarded the 1938 Nobel Prize in Physics for his work on induced radioactivity. Fermi is widely regarded as one of the leading scientists of the 20th century, highly accomplished in both theory and experiment. Along with J. Robert Oppenheimer, he is frequently referred to as "the father of the atomic bomb". He lived in the USA from 1938, building the world's first atomic pile (reactor) in 1942. He joined the at...

Marie Curie (November 7, 1867 - July 4, 1934) was a Polish-French physicist and chemist famous for her pioneering research on radioactivity. She was the first person honored with two Nobel Prizes; physics and chemistry. She shared her 1903 Nobel Prize in Physics with her husband Pierre Curie and with the physicist Henri Becquerel. She was the sole winner of the 1911 Nobel Prize in Chemistry. Curie was the first woman to win a Nobel Prize, the only woman to date to win in two fields, and the only person to win in multiple sciences. Her achievements included a theory of radioactivity (a term that she coined, techniques for isolating radioactive isotopes, and the discovery of two elements, polonium and radium. Under her direction, the world...

Giacomo Antonio Domenico Michele Secondo Maria Puccini (December 22, 1858 - November 29, 1924) was an Italian composer. His career extended from the end of the Romantic period into the modern period. Both during his lifetime and in posterity, Puccini's success outstripped other Italian opera composers of his time, and by only a handful of composers in the entire history of opera. A. Dupont, 1908.

Entitled: "Tomoegozen"; shows Tomoe Gozen, a female samurai, and another warrior, possibly Yoshinaka, on horseback. Tomoe Gozen (1157-1247) was a late 12th century female samurai warrior (onna bugeisha), known for her bravery and strength. According to one historical account, "Tomoe was especially beautiful, with white skin, long hair, and charming features. She was also a remarkably strong archer, and as a swordswoman she was a warrior worth a thousand, ready to confront a demon or a god, mounted or on foot. She handled unbroken horses with superb skill; she rode unscathed down perilous descents. Whenever a battle was imminent, Yoshinaka sent her out as his first captain, equipped with strong armor, an oversized sword, and a mighty bow;...

The Dodo is an extinct flightless bird. Its external appearance is evidenced only by paintings and written accounts from the 17th century. Because these vary considerably, and because only a few sketches are known to have been drawn from live specimens, its exact appearance in life remains a mystery, and little is known with about its habitat and behaviour Roughly the size of a swan, it was heavily-built, flightless and clumsy. Two species were known with certainty: the common dodo Raphus cucullatus from Mauritius which became extinct between 1665 and 1670, and the Rodriguez solitaire Pezophaps solitaria from the neighboring island of Rodriguez, which died out around 1761. The dodo's numbers quickly dwindled following the arrival of huma...
