The wonderful words "new daily life"、Being labeled with the outrageous epithet “With Corona”、Moreover, as expected, it was taken over by politicians.。It's really a waste。But in that case、What was your “everyday life” and “normal daily life” like?。I felt like it wouldn't be a bad idea to take another look at my feet.。

This is why、First, I decided to make a simple sketch of my current face.。First of all, appearance。For now, let's assume the age is less than 100 years old.。As of today (2021.2.5)、Height: 169cm、Weight 68.1kg、Body fat percentage 18.5% (slightly obese) and back pain for 8 years.。Avoid carrying heavy luggage as much as possible。bald on top of head、eyes are nearsighted、My ears are also quite far away.。Compared to friends of the same age, 10 years seems older.。What kind of silhouette do you imagine? A bent old man with a cane?

face? More than a true face、I have to draw the face first.。-The head is relatively small (probably the brain too)、Because I have a lot of hair that I don't take care of (there aren't that many)、When I look at my own shadow, it looks huge, like mohair.。My eyes are as thin as the size of a thread and a piece of wool (when I was in junior high school)、(It was often mistaken for falling asleep)、Thin eyebrows and drooping corners of the eyes。The nose is neither high nor low。Neither aquiline nor pointed nose、Basically an average nose。Don't talk。I can't open it particularly wide.、Because I'm not an idiot、Is this also normal?。However、What I noticed when I looked at my mother's photo、The shape of wrinkles that form under the closed corners of the mouth。I'm sure it wasn't there when I was a child.、Appears when you get older、this must be genetic。In terms of the whole face、The Earth's gravity is stronger as you go from the center line to the edges.。My jaw isn't particularly square, though.、He's not as thin as the handsome guy he is now.。But ok、I guess he's a very easy-going person.。I don't have any beard other than stubble.。My teeth are healthy、I have a dentist's approval for having missing teeth.。

Hobbies: I do write haiku.、I'm not so hooked on it yet that I can say it's a hobby.。I feel like I have to get a little deeper into it before I can call it a hobby.。But it's been going on for 10 years。My ambitious works often receive almost 0 points at haiku gatherings.。It's the type of phrase that makes you feel empty.。I have no connection to sports these days.、When I was young, I loved moving my body, so I'm still interested in it.。athletics、baseball、Sumo、swimming、mountain climbing、including skiing、I still want to do everything。Oh dear、Let's just say I love watching and doing it.。In one word, I love studying.、“The type who doesn’t seek results” (I was able to put it in a good way)。Speaking of words that I don't like, like effort and perseverance.、You should be able to imagine the level of achievement in studies and sports.。

write this far、Now that you can sketch your real face,、3 points out of 100 for “my view of sketching”、Wonder。I just published the primary data.。

Most of the day today、I was watching YouTube。Last night I happened to see a video by Kantaro Suzuki called ``Understanding Euler's formula through junior high school mathematics.''。２、3It became a hot topic a year ago、There is a link to a book with the same title.。I had seen a glimpse of the book at a bookstore at the time.、It was around the time that the movie ``The Mathematical Formula That the Doctor Loved'' was becoming a hot topic.。Last year, Professor Shinichi Mochizuki of Kyoto University、It became an international topic of conversation for completely proving one of the most difficult problems in mathematics, the ABC conjecture.。Although it was quite a while ago、More than 300 years after Fermat's death、Even when it was announced that ``Fermat's Last Theorem'', famous as a historically difficult problem that no one could solve, had been completely proven.、The whole world was excited。There seems to be a bit of a mathematics boom in the streets in recent years.。

including me、There must be a lot of people who are not good at mathematics.。However, even such a person、Into the abstract and concise world of mathematics、It is not uncommon for people to have feelings similar to admiration.。Mathematics is the first step to science。What has been proven mathematically、No matter how much you like it or hate it、Even if you don't feel comfortable with it, you can't help but admit it.。If there is such a thing as truth, this is it.、We somehow think that。I don't understand that at all、Rather than being embarrassed、I even feel in my heart that it might actually be bad.。But、Even if I pull out my math book,、I think most people will give up again because this is so unreliable.。

That's、Euler's mathematics、It is said that the mathematical formulas of great geniuses in the field of physics can be understood with the knowledge of junior high school students.、It was stuck in the back of my mind.。動画を見ると中学生までの数学しか使わないというのではなく、「中学生までの数学的知識があれば、その上に三角関数や微分積分などの説明を加えて」オイラーの公式まで理解できるようにするというものだ。確かに理解力のある中学生なら可能かも、と思わせる平易で見事な説明だった（中身は全然平易ではない）。興味ある方はご覧あれ。東大入試問題として有名な「円周率πが3.5より小さいことを証明せよ」も、さりげないがとても面白かった。

　流れで、ヨビのりたくみ氏（初めて知った）の「アインシュタインの（特殊）相対性理論」も見てしまったが、これも説明がじつに上手。こんな授業を中学、高校でやってくれたらもう少し違う道に進んだかもと思うが、それは仕方ない。corona、コロナで世の中沈む一方、しかも対策が支離滅裂状態だが、ハヤブサはちゃんと地球に帰ってくるし、地球の自転も一瞬だって止まらない。ただ現象だけにつられて右往左往するのでなく、Those that do not change、視点の置き場所を考えることで世界はもう少し違ってくると感じた一日。

Today is setsubun。例年なら2月3日なので、うっかりすると春を1日失ってしまう人がいるかもしれない。節分の翌日が「立春」で、暦の上では春になる。「二月」は一番寒い月とも云われるが、俳句の季語ではそういうわけで「春」に入るのだそうだ。

今日もパソコンでCGの練習。昨日覚えたことを、今日は完ぺきに忘れてしまう。自分の頭どうしちゃったんだろうと不安になるほど記憶力がなくなっている。練習で作った画像はパソコン上に残っているからやったことはわかるが、どうやってそれを描いたのか、描いた記憶自体がないこともある。ちょっと怖いです。

上の絵は「レイヤーマスク」という、基本中の基本のツールを使って描いた。10年も前から知っているのに、使えないまま今日まで来てしまった。まだぎこちないが、やっと半分理解できたような気がする。４９点？まだまだまだ。

コロナ感染拡大による緊急事態はどうやら延長されそうだ。こちらは一層厳しい「冬」が続く。まったく気が滅入る。絵でも描かずにはいられない。
