How smart is Einstein? :: essays research papers

There is a parlor game physics students play: Who was the greater genius? Galileo or Kepler? (Galileo) Maxwell or Bohr? (Maxwell, but it's closer than you might think). Hawking or Heisenberg? (A no-brainer, whatever the best-seller lists might say. It's Heisenberg). But there are two figures who are simply off the charts. Isaac Newton is one. The other is Albert Einstein. If pressed, physicists give Newton pride of place, but it is a photo finish -- and no one else is in the race. Newton's claim is obvious. He created modern physics. His system described the behavior of the entire cosmos -- and while others before him had invented grand schemes, Newton's was different. His theories were mathematical, making specific predictions to be confirmed by experiments in the real world. Little wonder that those after Newton called him lucky -- "for there is only one universe to discover, and he discovered it. " But what of Einstein? Well, Einstein felt compelled to apologize to Newton. "Newton, forgive me;" Einstein wrote in his Autobiographical Notes. "You found the only way which, in your age, was just about possible for a man of highest thought and creative power." Forgive him? For what? For replacing Newton's system with his own -- and, like Newton, for putting his mark on virtually every branch of physics. That's the difference. Young physicists who play the "who's smarter" game are really asking, "how will I measure up?" Is there a shot to match -- if not Maxwell, then perhaps Lorentz? But Einstein? Don't go there. Match this: In 1905, Einstein is 26, a patent examiner, working on physics on his own. After hours, he creates the Special Theory of Relativity, in which he demonstrates that measurements of time and distance vary systematically as anything moves relative to anything else. Which means that Newton was wrong. Space and time are not absolute -- and the relativistic universe we inhabit is not the one Newton "discovered." That's pretty good -- but one idea, however spectacular, does not make a demi-god. But now add the rest of what Einstein did in 1905: In March, Einstein creates the quantum theory of light, the idea that light exists as tiny packets, or particles, that we now call photons. Alongside Max Planck's work on quanta of heat, and Niels Bohr's later work on quanta of matter, Einstein's work anchors the most shocking idea in twentieth century physics: we live in a quantum universe, one built out of tiny, discrete chunks of energy and matter.

The Causes of Wwi

The long-term causes 1. Colonial rivalry-competition for even bigger empires 2. Balkan nationalisim-the desire of the Slav peoples of this area to join those in the empire of Austria-Hungary 3. The arms race-competition for bigger armed forces and more armaments 4. The Anglo-German Naval Race 5. Kaiser Wilhelm II and German militarism 6. Alliance system-The Tripple Alliance and the Triple Entente The immediate cause of the war 1. The assassination of Franz-Ferdinand 2. Russia’s backing Serbia made war more likely 3. German backing for Austria was crucially important Colonial rivalry-competition for even bigger empiresCompetition between the Great Powers in Europe to gain colonies plays an important role in causing the WWI. By the beginning of the twentieth century, many great powers in Europe has built up their empires by holding colonies or ares. This is known as imperialism and as means when a country takes over new lands or countries and makes them subject to their rule. Ma ny countries such as the British Empire were at the peak of their industrial revolution and their developments of industries were huge. When industrialism occurs, countries need foreign markets to sell their increase in goods.Great Britain had the the largest number of colonies in the world so that King George V was also the Emperor of India and ruler of many other lands overseas. The great Empire took up nearly a quarter of the world’s land surface with 390 million of population of the colonies in 1914. And also France has the second largest empire in the world with colonies in Africa, the Far East and Indo-China. Those large number of colonies improved Britain’s and France’s dominance over the Europe and made them powerful and influential. The Germans were left with some small and commercially marginal colonies.There was a great deal of jealousy in Germany in regard to the British and French empires. The King of Germany , Kaiser Wilhem envied the mighty Britai n Empire . He decided that Germany too must have colonies overseas, which would helped him expand the German Empire and provide Germany with a market for her growing industries. It would also be a status sybol showing Germany’s greatness and gaining it respect. ( Furthermore, Britain in particular, used its navy and merchant navy to dominate overseas trade, which also provided a source of irritation to the Germans. The Germans embarked on a program of massive naval spending in order to create a navy capable of challenging Britain's domination of the sea. This caused considerable concern in Britain and tensions between the Germans and the Britain. Once the trigger was fired, the assassination of the Archduke, Imperialism directly led to a naval arms race between the two countries. Causing the disparity of the power of different countries ,competition and tension between countries to grow , the Colonial rivalry made countries willing and eager to join World War I, which was see n as an opportunity to gain colonies and reshape the world.Therefore, German declared war on Russia and mobilized her army when Russia refused to send troops to help Serbia and other countries joined in the War later. On 5 August, all the great powers of Europe were at war with each other, WWI broke out. Balkan nationalism-the desire of the Slav peoples of this area to join those in the empire of Austria-Hungary Balkan nationalism is also one of the important factors of the outbreak of WWI. The Balkans is the area of south-west Europe and it was the powder-keg or trouble spot of Europe. This area had once been part of Turkish Empire.It was inhabited by Slav peoples such as the Serbs, Bulgarians and Romanians, who were able to rule themselves. Many nationalities were part of the Austro-Hungarian Empire but Serbia wanted to unite all Serbs within a greater Serbia. The Slav peoples of Balkans desired those in the empire of Austria-Hungary to join with them. Russia regarded herself as t he protector of these Slavs since they shared a common nationality. Austia-Hungary feard losing not only the Serbs but also other Balkan nationals so that Austria-Hungary wanted to take over the states of this area to preserve of this empire.It brought increasing rivalry between Russia and Austria-Hungary. When Austria started war with Serbia, Russia ordered the Russian army to prepare for war in order to help the Slavs of Serbia on 29 July, which started a countdown to the biggest war, WWI. German sent ultimatum to Tsar Nicholas to order him to stop mobilizing but Russia refused to accept and so Germany declared war on Russia , mobilizing her army. As France was an ally of Russia the French government ordered the mobilization of the French army on 1 August. Many other great powers joined the war later so that WWI broke out on 5 August.Causing the tension and opposition between Russia and Austria-Hungary to rise and making the mobilization of Russia which started the countdown of th e war,the Balkan nationalism made the war likely to happen. Therefore, the Balkan nationalism was one of the factors of the outbreak of WWI, The arms race-(competition for bigger armed forces and more armaments) The arms race also contributes into causing the WWI to break out. By the beginning of twentieth century , great powers in Europe have started to rival with each other through building up the size of their armed forces.Each major power in Europe except Britain had trained a huge army of conscripts, which means young men forced by law to become soldiers for a year or so. These armies could be mobilized at a moment’s notice. In the period 1900-1904 the main European powers more than doubled their spending on their armies. From 1872 to 1912, Germany increased more than 300% of her armaments spending when Russia increased more than 250% with Italy, Great Britain, Austria-Hungary and France around 100%. Guns , shells, bullets and other weapons had been stockpiled in case of war.Ever more destructive weapons were being developed and improved, such as the machine-gun and huge field guns. The increases in spending of armaments caused the military rival between countries to rise. The arm races increased tension between the Great Powers. They felt threatened when others increased its army and gained stronger weapons so that they competed with each other through making their military power stronger with a rolling ‘snowball’ effect. It made the war more likely since country increased its army and weapons it became more confident of success in a future war and more willing to test out their armed forces.When Austria started war with Serbia after the assassination of Franz-Ferdinand, Russia backed Serbia as a starting point of countdown of WWI . More great powers joined the large-scaled war soon later since they were confident and well prepared to compete their military powers. WWI broke out on 5th August 1914. Increasing the tension and competiti on between countries and accelerating the coming of the war , the arms race gathered all great powers together and made the war faster and more possible to happen. Therefore, the arms race was one of the most important factors of the outbreak of WWI. The Anglo-German Naval RaceThe Anglo-German naval race was also one of the factors of the outbreak of WWI. Before WWI,Great Britain had the most powerful naval in the world, which was her Royal Navy. The navy which outgunned and outnumbered all other navies not only protected the Empire and trade, but also prevented foreign invasion. At the same time, Germany had the world’s best army but Kaiser Wilhelm, but the German reluer would like to compete with Britain so that it began to build a fleet of battleships to rival the British Navy in 1898. Britain were not worried about the growth of the German fleet too much at first since they had enormous lead.However, the introduction of the powerful British ‘Dreadnought’ batt leship in 1906 changed all this. The dreadnought was faster, bigger and had a much great firing range than existing battleships and this super-battleship made all previous battleships obsolete or out of date. This allowed the Germans to begin building ‘Dreadnoughts’ on equal terms with Britain. A race developed between two countries to see who could build the most. In 1909 Britain had 8 Dreadnoughts to Germany’s seven. This naval race poisoned the relations between the two countries and was the main bone of contention between the two right up to 1914.When Germany was preparing to invade Belgium, the British sent her troops to protect Belgium from attack. British sent a telegram to call Germany to back her army. With no reply from Germany , the Britain started war with Germany and from then, all the great powers of Europe became at war with each other. On 5th August, 1914, WWI broke out. By worsening the relations between Germany and Britain and causing rival and tension between them to rise, the Anglo-Naval Race made the war between the two more likely to happen and it became a part a WWI. Therefore, the Anglo-Naval race was one of the factors of the outbreak of WWI.

German Language Lesson Writing Dates

Writing dates can differ from language to language and change with each context. Though it is taught from day one in class when you write the date on your page, often other ways of expressing dates are neglected. In German, it is, of course, the grammatical cases that one has to watch out for when writing these dates. Writing the Date in a Letter Stadt/city, den (acc.) 16.5.11Bonn, den 16.5.11 Bonn, den sechszehnten fà ¼nften zweitausendelf. Dates in Other Writing Contexts Stating the day of the week along with date:Am Samstag, dem 5. Juni, wurde er geboren.Samstag, den 5. Juni.Not stating the day of the week:Sie ist am 25. Juni geborenHeute haben wir den 25. Juni. (fà ¼nfundzwanzigsten)Heute ist der 25. Juni (fà ¼nfundzwanzigster)Stating from one date to another without indicating day of the week:Vom 16. Mai bis zum 20. Mai.Stating from one date to another while indicating day of the week:Von Montag, dem 16. Mai, bis Freitag, dem 20. Mai.
