I appreciate science's practical aspects, but I prefer knowing and learning more stuff just because it feels good.

Iridium, Why Was it Named After a Goddess?
What got me thinking about iridium this morning is that it's currently at $234/gram---more expensive than gold. Its volatile price, has gone up by a factor of 7 between 2018 and 202. It is influenced by the growing demand for iridium in the aerospace,…

It is influenced by the growing demand for iridium in the aerospace, electronics, and medical sectors. No other element is more resistant to corrosion than iridium, and only its "cousin" osmium is more dense.

Oak forests are now rare due to human exploitation, with old-growth forests—those with very large, long-lived trees and abundant deadwood—comprising only 1% of Europe’s forests. Deadwood, often dismissed as “useless,” stores carbon, enriches soil as humus, and supports countless saproxylic organisms
Wouldn’t God Love Oak Forests?
I was a friend's mom's funeral yesterday wondering about the existence of God. If there is a God, I thought, wouldn't he prefer that we prayed under trees instead of converting forests into oak pews? Oaks have caught my attention since I was 5, even though a relative ridiculed my fascination with acorns, something she thought was meaningless and commonplace. A White Oak can live for at least six centuries, and the genus,

The Search for Truth: Why Do We Value It?

The Search for Truth: Why Do We Value It?
A friend of mine asked several interesting questions. Something I've always found strange: the universe didn't have to be intelligible, yet it is. Why? Why does mathematics map the physical world so uncannily? Wigner called it ‘the unreasonable effectiveness of mathematics.’ Is that just a brute fact — or something deeper? Even when a truth is inconvenient, we still feel as human beings, obligated to assent to it (or search for it) .

Robert Bateman(1) spent 20 y teaching Geography in high school. He chose the discipline as an excuse to be outdoors. (2) was originally an abstract artist (3) has never had his works displayed at the National Gallery (4) his foundation uses art to promote a connection to nature and the environment.

This is may have served as the inspiration for the #BatSignal: In 1875, from the roof of the Siemens Halske factory in Berlin, electrically-generated rays were bounced off a large mirror and projected onto dark clouds while an awe-stricken crowd looked on. (Shown: 1875 Scientific American article)

New Mexico proposes world’s broadest use of PFAS warning labels
The state’s proposed requirements have not been done anywhere else and stem from a 2025 law that also outlaws PFAS in certain products

The author criticizes both alarmist narratives, which emphasize worst-case scenarios, & dismissive ones, which treat pesticide fears as mere “scare stories”.
It's not a “science vs. vibes” thing— public concern is more than irrational emotion; it's a legitimate risk perception. #pesticides

Merely because she was a woman, PhD Maria Goeppert Mayer, spent 1930 to 1960 without a permanent paid post. But 3 years later, she was the cowinner of the #Nobel Prize in #Physics for realizing that spin orbit coupling of nucleons led to magic numbers-why oxygen is more common than elements 3 to 7.
