There is not a single iota of evidence that large-scale planetary alignments cause changes in geologic events – like earthquakes and eruptions – on Earth. The only celestial bodies that could play some role – and there is some evidence that suggest that they may, in minor ways – are the Sun and the Moon. This is due to their relative close proximity (especially the moon) and their mass. I’ve covered some of this in my discussion of why the so-called “Supermoons” are silly and play no role in increasing/decreasing geologic events. What about the alignment with the galactic center? The center of the galaxy must exert some force on the Earth (and solar system) or we wouldn’t be orbiting it. However, beyond that fact that alignments like this happen all the time, the force that the galactic center exerts on Earth is ~0.00006x that of the Moon on Earth and ~0.00000037x that of the Sun, doesn’t it seem a little ridiculous to claim that the galactic center can change anything on Earth if the Sun and the Moon cause little-to-no effect on geologic events?

Teach with Picture Books: You Say You Want a Revolution? - 78 views
-
The American Revolution gave birth to a new country, but now, more than 200 years later, so many stories of this incredible time in history are yet untold. Most of us know about Paul Revere, George Washington, Thomas Jefferson, and perhaps even Molly Pitcher, but what of the smaller, yet equally important roles played by American Patriots?

For American teenagers, it really is harder to get into Harvard — or Yale, Stanford, Brown, Boston College or many other elite colleges — than it was when today’s 40-year-olds or 50-year-olds were applying. The number of spots filled by American students at Harvard, after adjusting for the size of the teenage population nationwide, has dropped 27 percent since 1994.
-
The share for any individual college is minuscule, of course. In 2012, about 33 out of every 100,000 American 18- to 21-year-olds were attending Harvard, down from 45 per 100,000 in 1994. These changes in the share tell you how much harder, or easier, admission has become for American teenagers on average. Between 1984 and 1994, it became easier at many colleges. The college-age population in this country fell during that time to 14.1 million in 1994 from 16.5 million in 1984, and the number of foreign students was relatively stable.
-
Over the last 20 years, several large colleges, like N.Y.U. and the University of Southern California, have improved markedly, effectively increasing the number of seats on elite campuses

What makes an interactive whiteboard interactive? - Doug Johnson's Blue Skunk... - 25 views
-
But many advocates of this technology (myself included), see IWBs as genuine means of bringing more interactivity, more student-focus into classrooms of traditional teachers
-
What we don't want to forget is that someone who is coaching a teacher is not really looking for "good technology use" but for just good educational practices. Having an IWB is not going to change a lecturer into something else.

Any item in the Instruction domain can be enhanced using an IWB.

Thinking about solar?
-
Green Ray Solar this week is expected to announce UL certification for a solar panel that puts out alternating current, rather than direct current as most solar photovoltaic panels do today. AC panels can be simpler to install and wire together than traditional panels, which makes a piecemeal approach easier,
-
Traditionally, solar panels are tied into a device called an inverter, which converts the direct current from panels into household alternating current. Strung together, several panels produce enough voltage to run an inverter which, sized for a rooftop array, is roughly as big as a computer monitor.
