　　　　　　“Camellia no Mi”　Pen

Every time I look at the camellia fruits (and seeds), I see the universe.、In fact, there may actually be something called "truth".、makes me feel empty-hearted。

Have you ever tried to separate a camellia fruit?。Even people who plant camellias in their gardens、Maybe you don't have that experience.。Before you know it, the fruit will burst、It is normal for the seeds to fall to the ground.。
but、I happened to be picking the fruit before it burst.、can see it。(Visually) there is a very simple seed there.、how were they connected、If you try to put them together, it becomes a very difficult puzzle.。Even though there are only this many、All have subtle convex and concave surfaces.、As long as it is three-dimensional、Enjoyable enough for puzzle lovers。

The camellia flower is of course beautiful, but、I am deeply fascinated by the mysterious charm of bursting fruit shells and seeds.。And、I can feel the beautiful “mathematics” there.。Especially for that species、Even though they look similar to each other, no two shapes are the same.、It makes me strongly aware that。That's probably、Each seed is not independent like pumpkin or apple seeds.、I guess it depends on how the seeds stick together.、Even so, each and every one of them、sharp, streamlined curves、have a curved surface、It's a beauty that I would call "mathematical" rather than "biological."。
It is well known that the Nautilus spiral matches the Fibonacci sequence.。I'm sure that such "mathematical logic" exists in camellia seeds as well.、dream about。

"Mysterious" is different from "unintelligible"。that's another dimension。The wonder is、At first glance, it seems easy to understand、“The more I think about it,、It's about the depth that draws you further (and you should be able to understand it properly in the end)、be believed)。Camellia seeds are filled with “100% wonder”。
I was not good at mathematics, but、I wish I had a teacher who taught me this kind of mystery when I was a child.、I would have loved math 1000 times more than I do now.、It is a sport that is firmly connected to the essence of current sports.。

"Perrot" is too hot

"Perrot Study" Watercolor

It's about time to look like autumn (I want it)。Heavenly Do-sama won't listen to such wishes at all.、While I was complaining、I'm creeping up in autumn、Nature is already well prepared for the winter ahead。What's not possible is "At the end of the day of the heavens..."、It's like a period film from the Showa era、It's like a girl's lines、I'm the one who's good。

If you thought it might not be in the supermarket、I saw it a few days ago、There were voices saying。Oh dear、9The month has passed midway、It's not surprising that it's out。

So、I tried drawing a persimmon。This means that it's a sketch from a photo.。In the photo, there are four persimmons、I'm on a pretty big platter。The dish is also a decent artist, so it's worth drawing.、I've dared to leave it out here。In this situation、The old-fashioned "dobud persimmon" looks better、Unfortunately, it's not at hand。Sometimes I see the persimmon growing in the garden passing by、I want it、I want to draw it、It is a sport that is firmly connected to the essence of current sports.。There was a persimmon tree in our garden too.、The harmful insects are severe、While extermination, the persimmon tree that should be protected will be damaged.、It's withered。It's quite difficult for amateurs to get rid of insects.。

As a picture、Fall is getting even more advanced、When the heat from the sun began to die down、The persimmon that drags through the long shadow of autumn,、Standing near the ground, embracing the flames of summer, beginning to disappear、I was aiming for that kind of atmosphere、The real world is still hot at 35°C。It shows a sense of "disastrous defeat" that it is not just "drained heat" but "hot heat in the fullest."。From this picture、I would be thrilled if you could get that kind of "frustration."。

Forget the heat

"One Summer Day" Watercolor

It was hot this summer。The average temperature in the first month of August was 2.3℃ in Kanto as well.、This was announced by the Japan Meteorological Agency.。From Tohoku to Hokkaido, the same month is 4.7°C.。It was truly a heat that could only be called abnormal weather.。

Apparently, the questioner thinks that "the concrete result of sketching" brings fun.、The past tense of "it was" seems to be too early。There are likely to be many days south of Kanto where the temperature is over 30 degrees Celsius will still be over this time.、It's possible that there will be some extremely hot days。That heat、Drawing such a picture can overcome it。The truly wonderful picture。I forget the heat when I draw。

This is the perfect place to spawn salmon。With a suitable gravel bottom、I remember that despite its shallowness, it was always a place with a dark spot of fish.。
