Strong enough to trot a mouse on

I mentioned today to my wife that I needed to remove the tea ball from my tea before it got strong enough to trot a mouse across (the Irish standard for how strong tea should be, but not to my taste for Pu-erh tea).

She wanted to know whether it was always the same mouse trotting across teacups, and we together decided that it should be different mice, but from a pure-bred lab strain.

That leaves the question of which strain.  The two most popular lab strains are C57BL/6 and BALB/c, so the question is which strain. The weights of C57BL/6J mice are given at, and there is clearly a major difference by age and sex of the mouse. At five weeks, a female is about 17g, and a male about 20g, but at 24 weeks, the numbers are more like 25g and 35g. BALB/cJ mice seem to be slightly lighter:

So how old and which sex is the standard mouse for trotting across a cup of tea?  Or should the standard be based on just the weight of the mouse?  Does the size of the feet matter? Are there special strains of mice bred by Irish tea companies for testing their tea?

YouTube closed captions are awful

I looked at the automatically generated closed captions on the Oscilloscope video and they were awful—pretty much just word salad. Speaker-independent voice recognition is obviously not a solved problem at Google.

I could not figure out from the captions what the text was supposed to be, so I’m definitely going to have to take an hour to edit the captions.  For your amusement, here are the automatically generated captions (with time stamps removed):


results go and circuits lab

we don’t have the output signal here in

going to connect our protocol but we
could have to ground lead to the ground

which is the signal that is a kind of

difficult connection to make now it’s
connected and we can see on the screen

the output of the mic channels now just
a distraction in the range goals

Update 2016 April 6: After about 5–6 hours of work, I got the closed captions fixed, so these amusing automatic ones are no longer on the video.  Editing the captions is even more work than editing the video, so I can see why so many people don’t bother!

A physics teacher’s reaction to anti-science witch hunts

Filed under: Uncategorized — gasstationwithoutpumps @ 12:06

Frank Noschese, a physics teacher, has written a rather amusing “letter to parents” on his blog Dear Parents | Action-Reaction, including such gems as

Giggle-inducing Scientific Terminology. Uranus, excited state, naked singularity, panspermia, ram pressure, Trojans, black hole, galactic bulge, hadron, space probe, parsecs, and 21-centimeter emission, to name a few. These are not “dirty words.” They are official scientific terms and we will need to use them in class.

The post as a whole mocks the anti-science attitude of the Dietrich, Idaho parents who protested a 10th grade biology teacher using the word “vagina” in the unit about reproduction. []

I guess that Idaho is racing Kansas to become the most anti-science state in the United States.

Fake websites

I was recently pointed to an excellent collection of fake websites, spoof websites, science spoofs, commercial fake sites.  This is a good place to find pointers to sites like the Pacific Tree Octopus, online pregnancy test, dehydrated water, dihydrogen monoxide, save the rennets, and other hoax sites.  There are over two dozen links!

Dangers of automatic markup

Filed under: Uncategorized — gasstationwithoutpumps @ 18:10

The FreeLibrary has automatic markup (with mouseovers) of acronyms.  This sometimes leads to ludicrous results as seen in this screenshot of a Google search:
