Today, a Scott Martelle LA Times article counsels Democrats to scrap impeachment moves in that such would detract from the main job - defeating Trump in 2020. In my mind there is another job and that is to deny Trump Republican endorsement next summer.

My inclination on what do with the trunk were our tree needed taking down would be to decide if the trunk could be made into chainsaw art, like St. Urho.

From Wikipedia:

“In electrodynamics, circular polarization of an electromagnetic wave is a polarization state in which, at each point, the electric field of the wave has a constant magnitude but its direction rotates with time at a steady rate in a plane perpendicular to the direction of the wave.”

Thus, as time passes the wave front moves forward and the electric vector describes a spiral. When the light wave enters the polarizing filter the electric vector will be in a specific position and if parallel to the filter’s plane of extinction, will be blocked. As the wave passes through the filter it will have rotated millions of times and so extinction can not be 100%.

So present your rock solid evidence that supports your claim, Steven.

Conservatives give more to charity and volunteer more than Liberals. Liberals expect the government to do all of their charity work so that they don't have to.

But oh yes there certainly are “Death Panels” - its just they go by a different name = Republican Senate.

You might be a Conservative if:
1. You believe that Trump had more people at his inauguration than Barak Obama.
2. You believe the Affordable Care Act included Death Panels
3. You believe Obama was or is a Muslim.
Fear not, Science has answered the question about why Conservatives are more prone to believe lies.
For the record, they are also more sensitive to information that indicates danger. (Sort of like Mexicans are invading the U.S. and committing heinous crimes.
I'm sure you recognize most of these so why not take a few minutes to educate yourself.

There is a story to be told and each viewer will write his/her own script. Mine is - “I wonder what ....”

First suggestion, save a copy of the original and work only on that copy. Second idea, practice practice practice on making selections. Third, try to imagine how the fur colors will distribute under the stick - this will be tough so do not give up too soon. Good luck.

To avoid this mirror difficulty is one more reason to go mirrorless. Now what about polarization at lens surfaces?

You are correct...there is a lot of misunderstanding around this topic. I'll try to explain based on the physics of the situation.

When light reflects off a surface at an angle, it is partially polarized at an angle parallel to the surface. The shallower the angle, the greater the polarization. This includes light reflecting at 45 degrees off the mirror in a SLR...film or digital. A linear polarizer may be at such an angle that it is "crossed" with the angle of polarization due to the mirror reflection, reducing the light that gets through to the metering sensor. When the mirror raises and the shutter opens, the light hitting the film or sensor gets no cross-polarization effect, resulting in overexposure...sometimes a little, sometimes a lot.

So the answer to your question is that a linear polarizer shouldn't be used anytime on a SLR/DSLR with through the lens metering.

To a much lesser extent, it may reduce light levels enough to interfere with autofocus operation, but that is not the primary reason.

Circular polarizer is used very loosely on these UHH threads and means the filter rotates. In the theory of optics there is technical circular polarization. Most physics of optics text books treat the subject.

The Court filing was a year ago. That there has been no proceeding means the case has no merit. The meat of the complaint is baloney.

OP regurgitates the substance of a Court filing not a Court decision. There is a big difference.

The fire sparks had to have come from somewhere. Restoration work on a wood structure was going on. It is feasible that metal reinforcement was being installed and that welding might have been involved. Then a flood of welding sparks would be feasible. But then why did the contractor not have fire suppression capability?

The basic thought in this OP has crossed my mind, but I think it is too early to speculatr. As the fire started at the top how could the ‘starter’ get up there un-noticed.
