I'm a retired middle school math teacher and cross country coach. Before teaching, I worked as a software engineer.

I am interested in computers, math, science, history, and politics. I enjoy running, amateur astronomy, drone photography, and programming.

Academics and technologists are sounding the alarm about a growing crisis in scholarship as we know it: AI-generated citations of nonexistent papers that have infested real journals. Despite being fake, the sources are widely assumed to be authentic the more they appear in published literature.
AI Is Inventing Academic Papers That Don't Exist -- And They're Being Cited in Real Journals
Academic articles from authors using large language model are creating an ecosystem of fake research that threatens human knowledge itself.

School districts are rushing to adopt "one chatbot per child" models, but decades of research shows learning is fundamentally social.

Here’s why isolating students with AI tutors may undermine the classroom interactions that actually support brain development. buff.ly/gv76wEl
The ‘one chatbot per child’ model for AI in classrooms conflicts with what research shows: Learning is a social process
AI tutors are often held up as an ideal, but prioritizing individualized teaching can detract from the benefits of learning in social environments.

Girls typically stick to the classic math formulas while boys wing it with shortcuts — and researchers say that difference may help explain why men still dominate high-stakes tests and #STEM. buff.ly/Gu59lvr
Girls and boys solve math problems differently – with similar short-term results but different long-term outcomes
The reasons are not yet fully understood, but researchers consider societal influences that encourage greater compliance among girls as a potential cause.

The Pacman Nebula. This is about 20 hours of imaging over 4 nights. It is about 9500 light years away from us and about 25 light years in diameter.

If we want to talk affordability, you know what would really help? Re-jiggering how we pay for college. There's a lot to learn from my native Australia, which has an incredibly fair and efficient system of income-based repayment.

The Triangulum Galaxy. This is the result of almost 24 hours of imaging over 5 nights. This galaxy is about 2.7 million light years away. It is about 60,000 light years in diameter, a bit more than half the size of our Milky Way galaxy.

Serious scholars have examined what happens when we change the number of H1-B visas issued.

Cities that get more H1-B immigrants subsequently see the wages of natives *rise* substantially.

Skilled immigrants bring new ideas, fill labor shortages and make us all more productive.
