ZapperZ asks about a possible “marker” for becoming a scientist in Astronomer Looks Back at Telltale Childhood, namely, jumping out a window with an umbrella to see if one can fly, after having watched Mary Poppins.
OK, now that’s freaking scary because *I* too did almost the same thing AFTER I watched Mary Poppins (hum… does this mean that Mary Poppins is a good indicator of future scientists?)
I didn’t try this — not even tempted. I’m not particularly fond of heights. Some few extremely low altitude stunts involved bicycles, but I never had all that much daredevil in me. I was able to injure myself doing more mundane things.
Rhett and Chad discuss strategies for learning student names. They both admit to being terrible at learning names. Add me to the list. When I was in the navy I had the advantage that nametags are part of the uniform, and the students also had name signs on their desks. (That helped a little less as my vision drifted away from being 20-20 and before I got glasses)
Is it a prerequisite to teaching physics that you be bad at learning names? Three data points here!
We need some.
National Zoo Runs Low on Bamboo Supply
The bamboo on the zoo grounds is annually cut back and usually regrows, the zoo said. This year, for reasons unknown, the normally tenacious species did not grow back.
As a result, more needs to be found.
I’ve run across some small bamboo stands while geocaching. The first time it was a surprise, to be hiking along and then find myself in the midst of a dense jail of green bars.
Notes from Steven Chu’s Senate confirmation hearings
“Will you take a lead, not just to talk about it, not just to opine about it, but actually do the things necessary to see if we can’t restart our nuclear industry?” asked Senator Jeff Sessions of Alabama. Tennessee Senator Bob Corker echoed the question later, asking Chu if he meant to “pursue nuclear now… all out now?”
Yes, yes, and yes, Chu replied. “Nuclear power is going to be an important part of our energy mix,” he told the committee, a position he has stated before. Chu noted that nuclear power provides 70% of the carbon-free electricity in the country. Still, he said it was important to continue researching better waste disposal and fuel recycling technologies, perhaps in collaboration with other countries.
Earth, observed at the Big Picture
Here’s one of the pictures. I find this one fascinating — try and guess the scale of the picture, i.e. the horizontal size of the photo should be about 20 cm. What distance does that represent on the picture? Click the link to find out.
SUPERUSELESS SUPERPOWER: Resistance to helium.
Legend has it that there walks a man with uncanny abilities. After a tragic blimp accident, this man has developed an immunity to Helium. As this man courageously inhales Helium, there is no effect on the timbre of his voice.
