2+ people were killed by the twin explosions which erupted at/near the finish line of the Boston Marathon on Monday afternoon.
28+people injured by the explosions, and a number of alternate locations have now been closed off and/or evacuated as well. A controlled detonation was also used to dispose of a potential explosive outside of the Boston Public Library, and the AP reports up to two more devices are currently being dismantled. source
Adrift in Orion’s stellar nursery and still in its formative years, variable star LL Orionis produces a wind more energetic than the wind from our own middle-aged Sun. As the fast stellar wind runs into slow moving gas a shock front is formed, analogous to the bow wave of a boat moving through water or a plane traveling at supersonic speed.
All this will encourage yet more homeowners, businesses and communities to buy solar panels as power from the grid gets more expensive. You can see where this is going: The EEI says it could become a feedback loop that eventually wrecks the whole US utility industry, or at least greatly diminishes it.
Eventually, people will only be using the grid as a backup, combining ever-cheaper solar panels with ever more affordable batteries to store the power for when the sun isn’t shining. That’s called an energy transition.
The gist is that as solar panels continue to get cheaper, more people will install and use them. This, in turn, will cause the traditional electric companies to jack up rates to offset the decreased usage (they have pay off long-term plant investments). And that, in turn, will cause more people to buy solar panels.
“‘This is a generation of kids that grew up with data science around them — Netflix telling them what movies they should watch, Amazon telling them what books they should read — so this is an academic interest with real-world applications,’ said Chris Wiggins, a professor of applied mathematics at Columbia who is involved in its new Institute for Data Sciences and Engineering. ‘And,’ he added, ‘they know it will make them employable.’”
