I’m using right away the coffee mag that I bought at Trident Cafe in Boulder, CO. www.tridentcafe.com
This is so cool to me because the top of “trident” like a fork is very similar to a Japanese Kanji, 山, which means a mountain. I appreciate this realization.
Trident cafe is must-visit cafe!

Zooplankton team! It’s wonderful folks helping each other and fixing together if someone hits a wall. This pic was a dinner at Tea House, an iconic restaurant of Boulder, CO. Thank you everyone and @cu-esiil.bsky.social kind support!

If you visit Boulder, CO, you should stop by Piece Love and Chocolate.
It’s so nice atmosphere and many delicious chocolates!

I grabbed a hot coco with marshmallow. It was sooooo nice! I also got some dark chocolates for a gift.

We are a member of FreshwaterH2O of @cu-esiil.bsky.social. We made the projects forward through team building, working together, and many discussions. We sometimes create dataset, analyze data, discuss the results, go hiking, and grab chocolate. This week was so productive!

My family visited the Hiroshima Peace Memorial Museum. Hiroshima is the site of the first atomic bombing in human history. I found this stone monument there.
War is the work of man.
War is destruction of human life.
War is death.
