Just added a new feature to most of the quizzes - pop-up periodic table! If your students happen to misplace their periodic table or you've activated tab-switch detection on an assignment, they can now use this instead. The pop-up calculator works alongside it, too! #chemed #iteachchem

"0.3 per cent of the world’s land area – yes, just the land – would be needed to meet the current energy demand from solar alone, which is LESS THAN THE CURRENT LAND FOOTPRINT OF FOSSIL FUEL INFRASTRUCTURE."
Why solar power is the only viable power source in the long run
Not only is solar more than capable of supplying all the world’s energy, in the long term it is the only power source that won’t fry the planet

About this Florida vaccine story:
When they were little - 1 yr and 3 1/2 - my two older boys, who’d had all their shots, got whooping cough.
We asked their pediatrician what would’ve happened if they hadn’t been vaccinated.
“Oh, they’d have died.”

If Ohio taxpayers are expected to fund private schools through vouchers, then the private schools need to publish the same data as the public schools, including attendance, graduation rate, and mandated state test scores
You start to wonder what private school scores would look like if they were forced to take every student like public schools do.

There’s a nonzero chance you will die from a cancer that could have been curable because people who couldn’t pass 7th grade biology and are scared of things like “mRNA” and “riboflavin” and “walkable cities” decided to make their ignorance everybody else’s problem
Over 120 mRNA cancer trials are now at risk as the Trump admin cuts funding & tells researchers to scrub “mRNA” from grant proposals.
What started as COVID fearmongering is now derailing life-saving cancer research.
Hope remains - but scientists say time is running out.

I taught Environmental Science for 14 years and when we got to the population demographics unit I saw attitudes among my students (especially girls) about having children go from mostly positive to mostly neutral to largely negative because of cost of living, climate change, and politics

We ran a randomized controlled trial to see how much AI coding tools speed up experienced open-source developers.
The results surprised us: Developers thought they were 20% faster with AI tools, but they were actually 19% slower when they had access to AI than when they didn't.

I used to show this slide in class when I taught Environmental Science and before I would show it I would ask how many students had heard that wind turbines killed birds (several), but when they saw the graph they always had lots of stories to share about their own cats being bird murderers
Evergreen reminder that wind turbines are not even remotely a leading cause of human-driven bird mortality. This is classic concern trolling in the interest of fossil fuels - if they really cared about birds they'd focus on domestic cats and building glass. And what's not shown here: climate change.
