Ask Emmy Questions

A typical conversation with Emmy about physics.

The blog is recovering from the transition to WordPress, but I’m still not fully confident in it. So We’ll turn to another corner of the social media universe for my procrastinatory needs this morning: Having Emmy answer physics questions on Twitter. The same deal as when we’ve done this before: If you’ve got a physics… Continue reading Ask Emmy Questions

This Week’s Reading in the Church of the Larger Hilbert Space

1 And the LORD looked upon the earth, and, behold, it was corrupt; for all flesh had corrupted his way upon the earth. 2 And the LORD said unto Noah, The end of all flesh is come before me; for the earth is filled with violence through them; and, behold, I will destroy them with… Continue reading This Week’s Reading in the Church of the Larger Hilbert Space

Scientific Commuting: When Does It Make Sense to Take Alternate Routes?

I am an inveterate driver of “back ways” to places. My preferred route to campus involves driving through a whole bunch of residential streets, rather than taking the “main” road leading from our neighborhood to campus. I do this because there are four traffic lights on the main-road route, and they’re not well timed, so… Continue reading Scientific Commuting: When Does It Make Sense to Take Alternate Routes?

The Bat Diet: Live Longer Through General Relativity

A scientific theory hasn’t really arrived until the cynical and unscrupulous find a way to use it to extract money from the credulous and gullible. This has posed a significant obstacle for general relativity, dealing as it does with gravity, which requires really gigantic masses to produce measurable effects. That makes it a little difficult… Continue reading The Bat Diet: Live Longer Through General Relativity

Calendrical Innovation

Union operates on a trimester calendar, with three ten-week terms (September-November, January-March, April-June), rather than the two 14-15 week semesters used by most other colleges and universities. This has some advantages in terms of flexibility– even science and engineering students get to take terms abroad, which is harder to swing in a semester system– and… Continue reading Calendrical Innovation

The Unexpected Leaping Ability of Bovines

I’m spending the day trying to get some work done on the book-in-progress, so I’m avoiding both work- and blog-related stuff. I don’t want to leave the site completely quiet, though, so here’s a question to ponder, relating to SteelyKid’s continuing fascination with Goodnight Moon: How does a cow jump over the moon? The father… Continue reading The Unexpected Leaping Ability of Bovines

Experiment vs. Theory: The Eternal Debate

Melissa at Confused at a Higher Level offers some thoughts on the relative status of experimental vs. theoretical science, spinning off a comprehensive discussion of the issues at Academic Jungle. I flagged this to comment on over the weekend, but then was too busy with SteelyKid and football to get to it. since I’m late… Continue reading Experiment vs. Theory: The Eternal Debate

The Astrophysics of Bedtime Stories

SteelyKid is a big fan of the classic children’s book Goodnight Moon, which, if you haven’t spent the last sixty-odd years in a cave, you probably know features a bunny saying goodnight to a variety of objects in a great, green room. The attentive toddler will find a lot to look at in the pictures–… Continue reading The Astrophysics of Bedtime Stories

The Physics Bus

SteelyKid, like most toddlers, knows a few songs, and likes to sing them over and over. Her repertoire is limited to “ABCDEFG” (the alphabet song, but that’s how she requests it), “Twinkle, Twinkle,” “Some man” (“This Old Man,” which I only figured out this weekend), and “Round and Round” (“The Wheels on the Bus”). I… Continue reading The Physics Bus
