I went for my walk after walk and I have to admit I love spring here much more than in Arkansas.
It was hot as hell! But it’s okay!!!

I feel heavy. The weight of grief fills my chest. So I decide to rest. Take a week. Watch spring bloom through my windowpanes.
Spring was probably your favorite season, when all the animals came out from their sleep. I remember those nights where deer would be in your garden and you'd share the wonder with a younger me.
And now it is spring again, just many years later. I am now an adult, just graduated in an environmental major. You would have been elated to know that I found my passion in yours.
And now you have passed in the season of renewal. The season that you dearly loved. It makes spring hard to look at. The world shouts "joy" and I sit in grief.
But next spring, after the cycle of summer and fall and winter flow, the blooms will come again. And I think then I will be at peace. The brightness of it all will make me smile in memory of you instead of this feeling now.
I will always grieve you. But I am excited for next spring. To see the joy in the new animals and birds and blossoms.
But until then, I will sit during this bloom in grief of you.

"The search has intensified for alternative energy-saving technologies for heating and cooling that don’t run on fossil fuels.
Now, by mimicking a desert-dwelling chameleon, Chinese scientists have developed a cheap energy-efficient, cost-effective coating on houses.
They say the new material could keep buildings cool in the summer or warm in the winter without using additional energy.
“Many desert creatures have specialized adaptations to allow them to survive in harsh environments with large daily temperature shifts,” said Dr. Fuqiang Wang, author on the paper describing the invention and researcher at the Harbin Institute of Technology. ��For example, the Namaqua chameleon of southwestern Africa alters its color to regulate its body temperature as conditions change.”

...Many systems, such as cooling paints or colored steel tiles, are only designed to keep buildings either cool or warm, and can’t switch between modes.
Inspired by the Namaqua chameleon, Dr. Wang and his colleagues wanted to create a color-shifting coating that adapts as outside temperatures fluctuate...
When heated to 68 degrees Fahrenheit, the surface began to change from dark to light grey. Once it reached 86F, the light-colored film reflected up to 93% of solar radiation.
“Even when heated above 175 degrees Fahrenheit for an entire day, the material showed no signs of damage,” reported Dr. Wang.
The team then tested it alongside three conventional coatings—regular white paint, a passive radiative cooling paint, and blue steel tiles in outdoor tests on doghouse-sized buildings throughout all four seasons...
In summer, the new coating was significantly cooler than the white paint and steel tiles, according to the findings published in the journal Nano Letters.
“During spring and fall, the new coating was the only system that could adapt to the widely fluctuating temperature changes, switching from heating to cooling throughout the day,” Dr. Wang added.
The researchers say that the color-changing system could save a “considerable” amount of energy for regions that experience multiple seasons, while still being inexpensive and easy to manufacture."
