Summer has ended

The turning of seasons in Japan is so swift that the other day I went sleep with the electric fan on and woke up crunching like a shrimp because of the autumn chill. I love it :)

Summer ends so quickly, I still have a leaps of newly ordered summer clothes that haven’t been touched. And now I gotta start looking for fall items to wear in I don’t know, maybe two weeks? Because literally I feel like winter will arrive in no time.

Anway, summer 2023 was special, I’ve leant about more things, met more people, went out more and use much more sunscreen than I ever expected.

I’ve also spent a lot of time looking up the sky

Yeah that’s what I do most of the time while waiting for the traffic light to turn green.

By the way, do you know why the sky is blue?

Back to Kawagoe after 6 years. The place hasn’t changed much. But I have.

People say the Sun is yellow in the middle of the day. No, it’s white.

You might already know that white light is composed of colors. A spectrum of seven colors: Red, orange, yellow, green, blue, indigo and violet, that’s how you have a rainbow.

White light comes down from the Sun, it will interact with all kinds of molecules and particles in the air.

The wavelengths that are closer to the sizes of the molecules will scatter more efficiently. Blue lights have shorter wavelength than the other, so it will bounce (scatter) more and sent into every other direction. That’s why the sky appears blue to us.

Checkout “Rayleigh scattering” for more details.

I don’t know them. But I did wish them happiness (in my head) :)

At a chopstick-making workshop where they teach you how to make… well, chopsticks.

Kadokawa Culture Museum

Such an unique place with a giant library and so many fun exhibitions.

It’s really huge.

Unveiling Tutankhamen: The Pharaoh’s Timeless Adolescence exhibition was going on. A cool experience on ancient Egyptian civilization.

This reminded me of Ōke no Monshō 王家の紋章 - A shojo manga collection that was piling up in my room when I was in middle school.

And why is sunset red?

As the Sun gets lower in the atmosphere, the path length of the light is much longer through the air. More atmosphere means more scattering, the sky slowly becomes deep blue later in the day.

With much more blue taken out, the Sun will eventually have no blue light left, so what color is it gonna turn? Well, the other side of the spectrum: redish.

Now excuse me, I gotta get back to Tokyo for my yakitori date :)
