1年半くらい大学で化学を学んだ現時点での化学の感想
こんにちは（？）
大学入って3学期分が経過して、大体の大学化学の様相がつかめたようなきがするので
とりあえずまとめておきます。
高校では理論化学・無機化学・有機化学の３つのパートに分けられていますが、
大学ではもうちょっと細かく深くなります。
物理化学
物理化学は高校の理論化学の延長です。
量子化学・（化学）熱力学・反応速度論の３つからなりたつ学問です。
量子化学は大学に入ってからしか勉強しないんすね。（それはそう）
化学対して定量的な見方を授けるのが物理化学の得意なことです。
数式ばっかりで理解には数学力がないとかなり詰まります。
偏微分とかね...
分析化学
有機化学者がてきとーに薬品をまぜまぜして
なんかできたわ！ｗってやるのはよいのですが
その何かは結局何なのか。
要するに化合物や系に対して数値的なあるいは構造的な情報を与えるのが分析化学のしごとです。
分析化学は高校の理論化学の中にしれっとちょっとだけいます。
溶液のｐHを求めるとか酸・塩基中和計算のあたりです。
高校では影がうすいです。
(そりゃ溶液の濃度分かっても楽しくはないよね)
ただし分析化学のうちでそういう高校の計算パートはごく一部です。
分析化学は古典分析と機器分析に分かれてます。
古典分析が高校でやった、滴定で濃度を求める、とか電池を使って溶液の濃度を
求めるとか、そういうやつです。これは計算ばっかり。
（僕は分析化学１は死にかけながら取りました。落とした人も結構いる？）
機器分析は機械を使って化学分析をするやつです。
そういう装置の仕組みとかを学ぶやつです。
（研究室の先輩がデータの読み方さえ慣れれば仕組みとかは知らんくっても問題ない
っていってました。僕も正直そうだろうなぁって思います。計算するのは機械がやるし。）
高校では暗記ゲーでクソ面白くなかった分野（個人差有）
ですが大学ではそれなりに面白い気がします。
ただ、僕が学んで来た無機化学が大学の無機化学の面白いとこをやっただけっていう可能性は否めないです。
無機の教科書の扱ってないとこはぱっと見 こういう性質あるから
知っといてねっていうtopicに見えるし・・・
無機化学１では量子論の触り・原子・分子の構造・結合・HSAB則
をやります。これなんで１年の春にやんないの？？？
あとHSABっててきとーに名前つけすぎじゃないですかね
無機化学２では錯体化学をやります。結晶場理論とか。
生化学
みんな苦しんでいる（直球）
生命の化学なんですが生命現象むずかしくね？
アミノ酸を覚えるとか、ATGCの構造と結合を覚えるとかそういう
苦しい暗記パートがあります。つらい。
ところがどっこい生化学２はそこそこおもしろいtopicがあったりなかったりします。
生化学３，４，５は頼むぞ・・・
生化学は高校でいえば有機化学の最後の方にいます。
２次構造とか、酵素の性質とか。
おまたせ♡
高校の有機化学は楽しかったっていう人もいるとは思いますが
（僕はそれほど高校時代楽しみを感じてません）
大学の化学ではそうではありません。
これとこれを混ぜるとこれができます。
反応機構はこれです。
覚えて、どうぞ
っての繰り返しです。
定量的な議論をする場面はほとんどありません。
有機化学３では数式を一切書いた覚えがありません。
ひたすら定性的な説明が続きます。
正直現状では そうなんだ！すごいね！よかったね！
という感想しか沸いてきません。
大学入試のパズル要素はほとんどありません。
あと教科書がでかくて重いです。
まぁこんなもん。
Final presentation What is depression?
Good morning everyone.
Some people may think it's not a good morning.
Some people may feel depressed because the exam is coming soon.
Or, I think that anyone who has lived for nearly 20 years has experienced at least one sinking feeling.
If it lasts only for a few days, you are maybe healthy, but if it lasts more than two weeks, you may have a mental illness.
The theme of my presentation this time is depression.
Depression may not be familiar to college students, however,
Statistics show that 1 in 15 people will suffer from it in their lifetime.
Don't you think it's surprising?
So I think it's not a loss and it makes sense for us to think about depression.
What is depression? That's a difficult question. It is difficult to define in modern medicine. Still, the symptoms are known. Symptoms affect the body as well as the heart because the body and mind are related. For example:
mental symptoms include a depressed mood and decreased interest in things.
physical symptoms include sleep disturbances, loss of appetite, and fatigue and so on.
Therefore, treatment of depression requires treatment of not only mental symptoms but also physical symptoms.
So what causes depression?
One of the major causes is stress. A lot of tasks that we university students face can also be a cause.
In addition, there is a personality that is easy to get depressed.
That is, Serious, responsible, and perfectionist personality tends to cause depression.
Most of all, according to modern psychiatry, the imbalance between the chemicals that control emotions in the brain, such as serotonin, noradrenaline, and dopamine, is thought to be a major factor. In other words, depression is a disease that cannot be cured without treatment.
And like other physical diseases, depression is understood to be caused by physical abnormalities.
This is something that cannot be emphasized enough.
What are the treatments for depression?
Treatment consists mainly of rest, psychotherapy, and drug therapy.
As mentioned above, depression is in a sense, illness caused by chemical substances so rest is neither a bad thing nor a reprimand. In fact, people who are prone to depression often do not get enough rest. In drug therapy, rational drugs are used to eliminate the underlying imbalance.
In convergence,
In my presentation, I explained the symptoms, causes, and treatment of depression.
As I said before, 1 in 15 people will suffer from the disease in their lifetime, so it will certainly be helpful to have the right knowledge. Also, please consider not only your body but also your mental health occasionally.
I hope that you can lead a healthy university life both mentally and physically.
Thank you for listening.
中間プレゼンテーションが７月にようやく終わるっておかしくないですかね・・・
ってな訳で最終プレゼンテーションは急にやってきました。
depressionをテーマにしたのは適度に書きやすそうだったからです。
テーマ選びに一番苦労するってのは中間プレゼンと同様ですね。
健康には気をつけましょう。
Mid term presentation "Food pioneer"
Good morning everyone.
In this presentation, I will introduce a person whom I respect.
All of a sudden,
Is there anyone who doesn't recognize this image? Is there anyone who has never eaten this food?
I'm sure he isn't. It looks really delicious. I want to eat it. I think everyone is the same. Even after breakfast.
I'm going to introduce Momofuku Ando, the inventor of this Cup Noodle.
This time I would like to introduce his life, achievements, and reasons for respecting him.
Momofuku was born in 1990. He was born into a commercial family and had a strong spirit of independence and challenge from an early age. A turning point came in 1945, around the end of the war. Many people suffered from food shortages after the war ended. There were a lot of people in those days along with street stall ramen.
Momofuku Ando realized the importance of food to society and decided to make instant noodles. Despite some twists and turns, he succeeded in making chicken ramen in 1958 and cup noodles in 1971. His passion for food never faded in his later years, and at the age of 91, he launched a project to turn cup noodles into space food and took charge of it himself.
In fact, the development was completed in 2005 and he was sent to space aboard a space shuttle.
He passed away at the age of 96, bringing 2 mottos of "Continuing to bring about innovation" and "to be creative." to Nissin, the company he founded.
I think Momofuku has two major achievements.
First, he made instant cup noodles. It has revolutionized the Japanese food culture since the end of the war and has supported our food even today.
Right?
Next, they developed the Japanese culture of instant noodles and spread it all over the world.
It is not too much to say that Cup Noodle is the soul food not only in Japan but all over the world. This is something Japanese can be proud of.
So, what do I admire about him?
First, he was doing business with the idea of saving people's trouble.
It is his philosophy that he decided to make cup noodles out of the difficulties of people after the war.
Second: It's amazing he lived to be 96, but he took on new challenges after he turned 90. I respect that aggressiveness.
In inclusion
I introduced momohaku's life, achievement, and the reason I advise.
Finally, I ’ m going to finish with quotation from him
"It's never too late in life."
Thank you for listening.
中間プレゼンテーションです。 日本の偉人か日本の名所の紹介の２択とのことでしたので、偉人を選択（どうしてこっち選んだんだっけ？笑）
僕はいわゆる朝ドラとかにはすごく疎い人間なのでまんぷく という朝ドラが放送されていたことは知りませんでした。
でもドラマにできるくらいにはinterestingな人生を送ってきた人ですね
プレゼンするうえでありがたいっす。
カップヌードルってカップめんの中でも１ランク上のおいしさだとは思いませんか？
もっと安いやつもあるんだけど、カップヌードルはそれを差し置いて選びたくなるおいしさがある。
まぁたまに食べるからおいしんだろうけどね
プレゼンのpowerpointはブログに乗っけられないみたい。
まぁたいそうなものじゃないからいいや。
Unit 2 A great vacation idea
Good morning, everyone.
Have you ever seen truly beautiful landscapes? Are you tired of the humid heat of Aichi?
Do you want to spend more comfortable place for travel?
If the answer is yes, I have the perfect the perfect vacation for you because Okinawa is known for its beautiful landscapes and, Okinawa is not so hot.
I will give you some information about Okinawa, and its highlights and activities you can.
OK, I’ll describe about Okinawa.
Okinawa is land of Japan, and we can visit there by plane.
Okinawa is southern of Japan ,however, as I stated earlier, it is not so hot because the humidity is low in Okinawa.
In addition, we don’t have to get passport to ravel Okinawa. That is big point because I don’t have a passport.
Now let me introduce Okinawa’s highlights.
First of all I want you to go shuri-jio a historical and traditional park. You will be overwhelmed by its beauty. Or if you have never been to Okinawa, its unoriginal, but I recommend Churaumi aquarium. In this aquarium, we can see a lot of sea animals. Of course, it is famous for Whale shark.
How about activities?
It is pleasant to swim in the sea of Okinawa. There are many spots we can swim near hotels. In addition, I recommend the activity of coloring Siesar ( Okinawan traditional guardian lions )
To conclude, I hope the information I’ve introduced you about Okinawa, its highlights ,and activities.
Finally, I’m going to finish with a famous saying
All journeys have secret destinations of which the traveler is unaware
Thank you for listening.
Unit1とは大きく異なったカジュアルなお題ですね
旅行プランの提案をせよ、ということです
旅行会社かな？
沖縄には２回行ったことがあるので助かりました。感謝してます
Unit1 The person I admire
Good morning everyone
We learned many people’s lives since we were born
How many great people we know and their lives?
Today I want to talk about a person I admire
His name is Alan Turning, a scientist
I’m going to talk about his life, achievement , and then I’ll tell you why I admire him.
He was born in UK in 1912
He had gift for mathematics and science and in 1931 entered University and majored in mathematics
At that time German cryptography called “enigma” had an overwhelming influence on UK during WW2, therefore he was ordered to decrypt that machine.
In the courses of his work he developed the theory of modern computers,and finally,when 1944 he broke enigma
He has two great achievements
First he pioneered computer and computer science
Second he broke enigma in WW2
I have two reasons for the question why I admire him
First Thanks to his work,he made WW2 shorter
Breaking enigma ended brutal war and as a result, helped many people
Second he contributed to computer science, and even now he makes our lives better
In conclusion, I talked his life, achievements, and a reason I admire
We can know science have potential to make world happier by learning his life, therefore I want learn much better
Thank you for listening
コンピュータの理論の原型をつくりあげたアランチューリングについての発表です
彼はいわゆるgiftedで数学、科学に才能を示しました。
数理を専門にした大学在学中にコンピュータの理論を作っていた(たぶん)
WW2のドイツの暗号機エニグマとの戦いは
結構いろいろあるけどそこは割愛
彼の偉業はコンピュータの理論原型を作ったことと、エニグマの解読により戦争を短期化させたことが挙げられます
(解読がなされなかったらもっとひどかったはず)
文法ミスあったら教えてください
二日連続で悪夢を見た
2日連続で悪夢を見た
追記 ３日連続で見ました…
明らかに何かがトリガーだと思うんだけど
いったい何がトリガーなんですかね？
