My article about the Roman Empire - part 1 (preface)

Hello, below is the first part of my article about the Roman Empire, which I would like to publish.

We should learn from historical events and extrapolate from them the effects of actions we undertake.
The greatest state in the ancient era had lasted for almost ten centuries. To imagine how long that period of time is we can think about Poland one thousand years ago. Bolesław Chrobry was the king Poland and the Polish state just started to formed. For us such time is almost unimaginable. Yet, Rome collapsed, after decades of internal struggles and uncounted smaller and bigger wars with barbarian invaders.
One of the many root causes standing behind the fall of the Roman Empire was extremely important, because of its vast impact on the other factors. That cause was strictly a economic one and it consisted of various elements such as currency depreciation, hyperinflation, soaring taxes, growth of the public bureaucracy prompting the need for even higher taxes, depravity of the emperors who introduced more and more calamitous regulations, crumbling trade as the effect of the coinage debasement and at the end, the whole disintegration of the contemporary financial system. Along with the deteriorating financial condition of the Roman State, military necessities had not been lower. The growing threat of the Persian Empire on the east, barbarian tribes on the Rhine and hunnic wave storming through European continent required a strong and big army with high morale. The army in the 4th and 5th centuries had known its importance for the stability of the whole state, thus soldiers’ financial demands were also expanding. But the authorities were not able to meet their demands and the effect of this was disastrous for the integrity of the Empire, because of the never-ending need for new recruits, multiple civil wars and riots with self-proclaiming emperors-generals. Hence, from the one side there was a worsening financial condition exacerbated by central economic planning and from the other – rising and never acquired military needs.
The Roman Empire fall because of its military weakness, which is true, but the reason for this lied in financial system and money. At the beginning of the 3rd century the roman state entered into a fatal economic spiral which had lasted till the end of its western part in 476 A.D. But deterioration of the empire’s economy had begun already in 1st century during the reign of Nero. To understand why we need to start with the Roman currency system.

The Museum of Art in Tel Aviv. Part I.

Today I finally visited the Museum of Art in Tel Aviv. The impression trumped all my boldest expectations. In one complex of buildings they have managed to place the diverse collection of masterpieces hailed from the period from the beginning of the 20th century till these days. A several halls are devoted to Israeli authors and encompass sculptures, paintings, and video installations that brace the whole aforementioned period.

In the first hall there are works that were made in the first half of the past century. They mainly depict the earlier proto-stages of the State of Israel and their ordinary inhabitants: portrets, genre-paintings. Some of the canvases reminded me the Soviet Art of those pre-war times. For example, the mostly blue and white colored canvas with few construction workers who are erecting a new building with some older oriental-styled houses on the background. The work obviously praises achivements and the spirit of those builders.

This hall also displays some horrific works related to the Holocaust. The most hairy exhibit is the square bas-relief made of iron or copper which constitutes a ripped blanket or cover with vividly inanimated doll-like children' heads looking out of the holes. Another one canvas was painted of thousands of 6-digits numbers which, as far as I understand, are the numbers, that were tattoed by Nazis on the hands of the holocaust victims.

Watching an opera

Last year I watched the opera Rigoletto by Verdi. It was well worth watching it! It was stunning and breathtaking! I liked the way the players sang and how they were dressed. For me the highlight was the sounds, you could hear everything really well. The opera was a bit long for my liking but in the end It really lived up to my expectations! I would reccomend this show to anybody not convinced by opera.

Personal Statement

When I was a freshman, my head teacher told me that we should reproduce sewage and remove dust to show a more beautiful wold, which may be the goal of everyone who is major in environmental engineering. I choose environmental engineering as a major is a coincidence, but studying and working in the field about ecological environment is my plan of the future. It is my ideal to recreate the past beautiful scenery by dedicating to the treatment of pollution and the protection of the ecological environment.
The school motto of Zhengzhou University is “to be firmly believed and benevolent, and to be deliberative and diligent”. It has always been regarded as the quality that today's college students should have. I also constantly remind myself by it. I just try to be firm and unyielding and to go on step by step towards my goal. "I don't considerate whether I can succeed. Since I chose to go far, I only care about the wind and rain." This has always been my belief.
