WASHINGTON (AP) ? President Barack Obama wants Congress to help states rehire teachers and act on a key part of last year's jobs bill. He says the last thing the U.S. needs is to have fewer teachers in our schools.
Obama says in his radio and Internet address Saturday that many states have been squeezed by the economic recession and have been forced to lay off teachers ? about 250,000 across the nation.
Obama says Congress needs to act on part of last year's jobs bill that would prevent more layoffs and rehire more teachers who lost their jobs.
Republicans say Obama's policies stand in the way of a stronger economy. Minnesota congressman Erik Paulsen says House Republicans will push plans to boost domestic energy production and stop tax increases on small businesses.

Are you sick of reading about the transit of Venus this year? Yes? Me too. But the fact is that when astrophysical objects move between us and something else, like the convenient blaze of a star, there is an extraordinary amount that can be learned. I won?t go far into the delights of a venusian transit here, since so much has already been written about both the historical viewing and this year?s viewing (don?t stare directly at the Sun for goodness sake), except to say that in case you?re curious here?s a small listing of some Venus transits of the past, present, and future (thanks to NASA):
But if a transiting planet now sails across the disk of the star it will sometimes block more of the redshifted photons and sometimes more of the blueshifted photons ? depending on its path across the sky. The two slides here are from a class I teach at Columbia University, and summarize the impact of this varying blockage of light.
In a nutshell, if you measure the spectrum of the starlight simultaneously with a transit you will find it shifting redder and bluer with a very specific dependence on the actual geometry of the path the transiting planet takes. It can appear as if the velocity wobble of the star due to the planet?s gravity is itself somewhat askew.

Yes, he used beer bottles to plan our garden.? It sure takes the concept of a beer garden to a whole new level!? You could easily use stones, old pots, or whatever you have on hand.
