Input: Read this: Some alloys occur naturally, such as electrum, which is an alloy that is native to Earth, consisting of silver and gold. Meteorites are sometimes made of naturally occurring alloys of iron and nickel, but are not native to the Earth. One of the first alloys made by humans was bronze, which is made by mixing the metals tin and copper. Bronze was an extremely useful alloy to the ancients, because it is much stronger and harder than either of its components. Steel was another common alloy. However, in ancient times, it could only be created as an accidental byproduct from the heating of iron ore in fires (smelting) during the manufacture of iron. Other ancient alloys include pewter, brass and pig iron. In the modern age, steel can be created in many forms. Carbon steel can be made by varying only the carbon content, producing soft alloys like mild steel or hard alloys like spring steel. Alloy steels can be made by adding other elements, such as molybdenum, vanadium or nickel, resulting in alloys such as high-speed steel or tool steel. Small amounts of manganese are usually alloyed with most modern-steels because of its ability to remove unwanted impurities, like phosphorus, sulfur and oxygen, which can have detrimental effects on the alloy. However, most alloys were not created until the 1900s, such as various aluminium, titanium, nickel, and magnesium alloys. Some modern superalloys, such as incoloy, inconel, and hastelloy, may consist of a multitude of different components.
Question: Iron and what metal formed the first alloy made by humans?

QUES: The great angiosperm radiation, when a great diversity of angiosperms appears in the fossil record, occurred in the mid-Cretaceous (approximately 100 million years ago). However, a study in 2007 estimated that the division of the five most recent (the genus Ceratophyllum, the family Chloranthaceae, the eudicots, the magnoliids, and the monocots) of the eight main groups occurred around 140 million years ago. By the late Cretaceous, angiosperms appear to have dominated environments formerly occupied by ferns and cycadophytes, but large canopy-forming trees replaced conifers as the dominant trees only close to the end of the Cretaceous 66 million years ago or even later, at the beginning of the Tertiary. The radiation of herbaceous angiosperms occurred much later. Yet, many fossil plants recognizable as belonging to modern families (including beech, oak, maple, and magnolia) had already appeared by the late Cretaceous.

When had eight main groups of Chloranthaceae recognizable as belonging to modern families appear?

QUES: Other historians find incongruity in the proposition that the very place where the vast number of the scholars that influenced the scientific revolution received their education should also be the place that inhibits their research and the advancement of science. In fact, more than 80% of the European scientists between 14501650 included in the Dictionary of Scientific Biography were university trained, of which approximately 45% held university posts. It was the case that the academic foundations remaining from the Middle Ages were stable, and they did provide for an environment that fostered considerable growth and development. There was considerable reluctance on the part of universities to relinquish the symmetry and comprehensiveness provided by the Aristotelian system, which was effective as a coherent system for understanding and interpreting the world. However, university professors still utilized some autonomy, at least in the sciences, to choose epistemological foundations and methods. For instance, Melanchthon and his disciples at University of Wittenberg were instrumental for integrating Copernican mathematical constructs into astronomical debate and instruction. Another example was the short-lived but fairly rapid adoption of Cartesian epistemology and methodology in European universities, and the debates surrounding that adoption, which led to more mechanistic approaches to scientific problems as well as demonstrated an openness to change. There are many examples which belie the commonly perceived intransigence of universities. Although universities may have been slow to accept new sciences and methodologies as they emerged, when they did accept new ideas it helped to convey legitimacy and respectability, and supported the scientific changes through providing a stable environment for instruction and material resources.
What percentage of students from 1450-1650 in the Dictionary of Scientific Biography were taught at a university?

Philip II was a strong and expansionist king and he took every opportunity to expand Macedonian territory. In 352 BC he annexed Thessaly and Magnesia. In 338 BC, Philip defeated a combined Theban and Athenian army at the Battle of Chaeronea after a decade of desultory conflict. In the aftermath, Philip formed the League of Corinth, effectively bringing the majority of Greece under his direct sway. He was elected Hegemon of the league, and a campaign against the Achaemenid Empire of Persia was planned. However, while this campaign was in its early stages, he was assassinated.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who annexed Thessaly and Magnesia?
Ah, so.. Philip II

Question: In surveys made in Europe and the United States, green is the color most commonly associated with nature, life, health, youth, spring, hope and envy. In Europe and the U.S. green is sometimes associated with death (green has several seemingly contrary associations), sickness, or the devil, but in China its associations are very positive, as the symbol of fertility and happiness. In the Middle Ages and Renaissance, when the color of clothing showed the owner's social status, green was worn by merchants, bankers and the gentry, while red was the color of the nobility. The Mona Lisa by Leonardo da Vinci wears green, showing she is not from a noble family; the benches in the British House of Commons are green, while those in the House of Lords are red. Green is also the traditional color of safety and permission; a green light means go ahead, a green card permits permanent residence in the United States. It is the most important color in Islam. It was the color of the banner of Muhammad, and is found in the flags of nearly all Islamic countries, and represents the lush vegetation of Paradise. It is also often associated with the culture of Gaelic Ireland, and is a color of the flag of Ireland. Because of its association with nature, it is the color of the environmental movement. Political groups advocating environmental protection and social justice describe themselves as part of the Green movement, some naming themselves Green parties. This has led to similar campaigns in advertising, as companies have sold green, or environmentally friendly, products.
Try to answer this question if possible: What does the Mona Lisa wearing green symbolize?
Answer: she is not from a noble family

Question: This new approach liberated scientific speculation from the dogmatic restraints of Aristotelian science, and paved the way for new approaches. Particularly within the field of theories of motion great advances were made, when such scholars as Jean Buridan, Nicole Oresme and the Oxford Calculators challenged the work of Aristotle. Buridan developed the theory of impetus as the cause of the motion of projectiles, which was an important step towards the modern concept of inertia. The works of these scholars anticipated the heliocentric worldview of Nicolaus Copernicus.
Try to answer this question if possible: Which scholars made great advances in the theories of motion?
Answer:
Jean Buridan, Nicole Oresme and the Oxford Calculators
