Apparently, this piece of equipment gets rid of complications a simple linear polarizer causes with (partially) reflective parts inside the camera.

Nevertheless, the second step, the quarter-wave plate, works exactly as described above only for one fixed wavelength of light $\lambda_0$ (this could be e.g. the wave-length of orange light). For other wavelengths (other colors of light), it introduces a slightly different phase shift.

At the end of the episode, Rick not only gives Carl back his gun, but also puts his Sheriff's belt back on with gun in its holster. He wants to be a good father and role model for his kids, but just because he's tuning the zombie apocalypse out with earbuds, doesn't mean it isn't happening.

However, I have just learned that in photography, the word "circular polarizer" is actually used for a linear polarizer with a quarter wave-plate. In other words, "circular polarizer" in photographic equipment means an optical element which ideally does the following:

Forget the walkers. People are getting sick and are becoming walkers overnight! As a result, we said goodbye to Karen (who we barely knew to begin with) along with 14 to 15 others.

5. Now that Carl has his gun back, is he going to get trigger happy again?   At the end of last season, Carl shot a teen in cold blood. Will he start abusing his power? It doesn't look that way. He went straight to his dad and told him Carol's training girls to fight with knives. As well, he seemed slightly distraught he had to pick up a gun to defend Michonne from an onslaught of zombies.

In other words, if you ordered a photographic polarizer, it will be most likely either be a linear polarizer, or a linear polarizer with a quarter-wave plate. Both of them should dim and brighten an LCD screen when rotated and used in the designed direction, but you can tell between the two when you flip it. Then the simple linear polarizer will work exactly the same, but the circular one will work different; it should show less dimming/brightening when rotated and possibly some color variations to the light when flipped.

I have a polarizer which has CIRCULAR PL written on it. This suggests it is a circular polarizer even though I am supposed to have a linear one.

The producers keep telling us that they're planting the seeds right now to lead to some explosive storytelling later in the season.

We quickly learn something's off with Lizzie. The girl has a HUGE attachment to the zombies — she names them and seems more concerned about "Nick's" death than her father's. Naturally, it looks like she may be the one feeding the walkers. (But there's no way she could drag two bodies out and burn them.) Plus, it doesn't help that her sister says "She's messed up. She's not weak."

I.e., if linearly polarized light of various wavelengths enters the quarter-wave plate, it will emerge from it with various degrees of elliptical polarization (essentially a mix of linear+circular polarizations) from it, dependent on its wavelength.

Executive producer Greg Nicotero made it clear on after show "Talking Dead" the contagious virus spreading around isn't Swine flu.

Linearpolarization

If you use the polarizer in the way it was designed, it doesn't really matter, because your eyes are unable to detect polarization anyways. However, it changes if you flip it around. Then the light from a linearly-polarized source such as an LCD display gets first shifted in a color-dependent way, and then, based on this shift, filtered out by the linear polarizer. As a result, the flipped photographic "circular polarizer" applied to linearly polarized light will filter out some colors more and some colors less.

Sure, it was chock full of zombie action — plenty of kills, guts, and gore to keep us satisfied. An entire attack on one of the cell blocks filled nearly half the episode before another threat from the outside kept Rick and the gang occupied, but other than that it was a slow-moving episode.

Fans have been asking for blood, and we're getting it. Zombie Patrick stuffed his face with guts and blood, heads were stomped on, and walker heads started slicing through fences. After last week, "The Walking Dead" team is definitely getting more creative with its zombie kills.

You can learn more about polarization reading Hecht's textbook "Optics, 5th ed" (Pearson education, 2016, or previous editions), or a more especiliazed texts such as that from Goldstein "Polarized ligh" (Marcel Dekker, 2003), as well as the more recent from Jose Jorge Gil and Ravizgor OssiKovski "Polarized light and the Mueller matrix approach" (CRC press, 2016)

There is a number of ways you can find out whether you are dealing with a polarizer of a given kind, this is because 1) light reflected off surfaces is partially linearly polarized, 2) polarizers of a certain kind polarize your light and you can use that to compare with your polarizer, and 3) LCD screens emit linearly polarized light. As a result, you can do the following to tell which polarizer you have

A circular polarizer is often a combined $\lambda$/4- retardader, and a linear polarizer having its transmision axis at 45 deg with the optical axis of the retardader. A linear polarizer cannot transmit light having the electric field vibrating perpendicular to its transmision axis.

On one hand, You can distinguish between the two as the linear polarizer cancels light reflected in a surface at the Brewster angle of incidence, i.e, you cannot see the reflexion. The transmission axis should be in the vertical direction. On the other hand, the circular polarizer differentiates circular polarized light that rotates counterclockwise or clockwise direction. Circular polarizers are often used as antireflection coatings in displays screens, as the light impinging in the display is circularly polarized rotating in one direction when previously transmitted by the circular polarizer, but after reflection then rotates in the opposite direction, and the circular polarizer cancels transmission to the observer.

Not only are people dropping like flies, but someone's killing innocents as well. At the end of the episode, two burned bodies are found. Plus, zombies are also getting fed rats. Is the same culprit behind both?

He revealed the illness is actually based on the influenza from The Great Pandemic of 1918 to 1919. It's estimated that 30 to 50 million people passed away worldwide. 675,000 were Americans.

EDIT: The meaning of the word "circular polarizer" as I use it in the first part of the answer above is an optical element which filters out the light of a given circular polarization and leaves only the complementary one. (In practice this could be for instance achieved by a combination of a quarter-wave plate, a linear polarizer, and a 3/4-wave plate.)

The machete-wielding woman broke down while holding Rick's daughter Judith. Did Michonne once have kids, was she pregnant, or does Judith just have the power to bring every strong character on this show to their knees (see Daryl)?
