And then he recounted a story in which a political staffer was forced to resign after using the term niggardly—an unfortunate choice of words, perhaps, but not technically an offensive choice. Niggardly means stingy or cheap and is supposedly derived from the Norse verb nigla. (The staffer was ultimately reinstated.)

Comedy Central's Stephen Colbert took her up on it, calling Palin an '[expletive] retard' and adding, with a smile: 'You see? It's satire!'"

An optical prism is a solid block of optical material. The sides are flat and polished, and meet at precise angles. Optical prisms can be used to invert or rotate images, to deflect or deviate light, or as a beamsplitter, to separate light into its polarization states or component wavelengths.

But did that apply to the developmentally disabled? I'm honestly not sure. I only have one family story that has anything to do with that.

I was her first baby. She was three weeks from her due date, and it was almost Halloween. She and my dad were at the movies, and suddenly she had an overwhelming craving for candy corn, so he got her some. The next day, her friends threw her a surprise baby shower.

His article on the topic was published in The Washington Post in February 2010, the month before Tim Shriver's Special Olympics launched a special awareness day for its "Spread the Word to End the Word" campaign, and months before President Obama signed legislation officially removing the word from federal legal-ese.

Where temperature gradient is high, you will need to choose a window with very high thermal stability. Expected pressure, potential chemical reactions, and environmental abrasion are other factors you will want to consider when choosing your optical windows.

Actual references to retarded intelligence did not come until the 1900s. Tim Shriver, head of the Special Olympics, ties that to the development of IQ tests, which first became popular at the turn of the 20th century. And that led to a whole new toolbox full of terminology.

"Hey!" the friend would say, "I got your birth announcement! Congratulations! Cute picture! How's Annabelle liking having a little sister?"

Retarded is rich, satisfying in its cruelty. It's a word that gets its point across, perfect when you're describing a politician or that guy who just cut you off in traffic. Sometimes there's no good substitute—and yet it's gone.

One day I walked into her second-grade classroom to volunteer; the kids were learning how to use computers. Every other kid was on the correct screen, learning a basic function. Sophie had found her way to the Target website and was shopping for Olivia the Pig merchandise. The teacher smiled and rolled her eyes, and I suppose I should have scolded Sophie. But I couldn't. I loved every bit of her.

And then one day around Sophie's 7th birthday, I woke up and realized Sophie had become her own little person—something I'd long ago decided would never happen. I was wrong. She had ideas and opinions—sometimes even stronger than those of her peers.

At the time, I really did not understand what Down syndrome was. I think I knew that Corky, the kid from that '80s TV show, had it, and that the baggers at Safeway—the chubby ones with the round glasses who made me uncomfortable, the ones I always avoided—had it, too.

I was raised by liberals. We would never, ever make fun of a black person or scorn a Mexican. We were good people—agnostic Jews who believed in the Golden Rule.

"In some respects, the comparison seems overblown," Fairman said. "The N-word invokes some of the foulest chapters in our nation's history; 'retard,' however harsh, pales in comparison."

She was cute, I knew I should love her, and I did love her, in some basic way. But she wasn't just my daughter in the same way our older child, Annabelle, was. It was never that simple, not for many years.

A retroreflector is typically formed from three optical surfaces arranged to form a corner, although solid retroreflectors (corner cubes) are made of solid glass. These optics reflect an incident beam onto itself, and are used for making distance measurements as well as for alignment of various laser-based systems.

After my conversation with Sophie, I thought about it for days, caught myself every time I used the word, took note when others did. I started thinking about all the other euphemisms for stupid—dumb, idiot, moron, imbecile—and the more creative ones like mouth breather and drooler. And then I felt sick.

The performance of each optical component depends on substrate and coating used as well as form and finish.  Shanghai Optics is a leading custom optical component manufacturer of high quality optical elements from a variety of different optical substrates. These optics have applications in fields ranging from microscopy, medical lasers, and imaging to surveying, interferometry, satellite, and data transfer.  Our factories are fully equipped to produce the highest quality precision optics, and state of the art metrology equipment allows us to ensure that every component produced in our factory fully meets all relevant standards.

I was so busy worrying about the parts that I didn't let myself consider the sum. When Sophie was born, I abandoned the luxury of simply sitting back and enjoying my kid. Instead, I made doctor appointments and looked for therapists and fought with school administrators.

"Then why would you get the amnio?" Ray asked. "You're six months pregnant. What are you going to do, get a late-term abortion?"

Looking back, I'll admit that I didn't get the amnio because I was afraid of a long needle and a painful abortion rather than because I was OK with having a kid with Down syndrome.

An optical mirror is used to focus, redirect, and image light. We carry plane, spherical, and pyramidal mirrors in various substrates and with a range of different coatings.  Our precision optical mirrors are carefully manufactured to provide optimal surface quality, high clear aperture and very tight tolerances.

Listen, I'm really embarrassed about our conversation this morning about Sophie. I didn't know what to say. And I've been thinking about her and you all morning, and I just want you to know that I said the wrong thing. I mean, when I said that I was sorry about Sophie and Down syndrome, that just came tumbling out. Since then, I've realized it was a stupid thing to say, because Sophie is going to be fine. She's just going to be Sophie.

Those seemed like pretty good odds, but the guy looked so serious I got a little spooked. I called my husband, Ray, and explained the whole thing in a rush, telling him that there is a risk of miscarriage associated with amniocentesis, a procedure where doctors use a long needle to take a sample of the baby's amniotic fluid.

Sophie loves the story. She doesn't know the part my mom and I stopped telling after Sophie was born. A few weeks before I was born, the phone rang. My mom picked it up. It was a strange woman.

Things escalated, as Fairman explained, when former GOP vice presidential candidate Sarah Palin, who has a son with Down syndrome, "quickly took to Facebook to demand Emanuel's firing, likening the offensiveness of the R-word to that of the N-word."

Microscope objectives are perhaps the most important components of an optical microscope because they are responsible for primary image formation.

On a cool winter day in 2003, I went in for an ultrasound—the non-routine, high-definition kind where they can see everything. I was 36 and six months pregnant with my second child and I should have been scared shitless given the serious look on my doctor's face, but I was oddly calm as I waddled toward the elevator.

And then the syndrome was officially named after him. Why not name it after Jerome Lejeune, the man who put that theory to rest once and for all by discovering the third 21st chromosome? Or just call it trisomy 21?

When I first heard noise about the move to switch the accepted term from mentally retarded to intellectually disabled or cognitively disabled, I balked. I actually liked (and continue to like) the term mentally retarded. I think it does a better job than the others of describing what the situation is. In some ways, Sophie is slower than the rest of us in our house.

"If interest groups want to pour resources into cleaning up unintentional insults, more power to them; we surely would benefit from greater kindness to one another," Fairman concluded. "But we must not let 'retard' go without a requiem. If the goal is to protect intellectually disabled individuals from put-downs and prejudice, it won't succeed. New words of insult will replace old ones."

Optical windows pass electromagnetic radiation from one environment to another, and are typically designed to maximize transmission over a given wavelength range. The ideal substrate for an optical window will depend both on the wavelength transmission desired and the environments on both sides of the window.

A week earlier, I'd sat on another exam table in another medical building a few blocks away, shivering in a paper dress as my obstetrician suggested I get an amniocentesis. A blood test that screens for birth defects had come back showing an elevated risk of Down syndrome, he explained, and amniocentesis would create some certainty.

I called her during one of my drives and broke the news straight out. She gasped and started crying, saying, "Oh no, oh no, oh no, oh Amy, I'm so sorry."

We also manufacture both polarizing and unpolarizing beam splitters. A beam splitter, as its name suggests, splits a beam into two separate components. Cube prisms are manufactured from two right angle prisms, cemented together along the hypotenuse. They shorten the optical path of the system, and are used with 0 degree angle of incidence.  A plate beamsplitter is a thin glass plate, coated on the first surface.  These beamsplitters are often optimized for 45 degree angle of incidence.

Like a former cigarette user offended by secondhand smoke, I became the first with a dirty look or an admonition when I heard someone else use it.

It's commonly assumed that people with Down syndrome have above-average-sized tongues, because they often protrude from their mouths. The truth is that there's nothing different about their tongues; but people with Down syndrome do tend to have smaller mouths, making it appear as though they have super-long tongues. They also can have breathing problems because all of their openings—including nasal passages—tend to be smaller than average. And because they have weaker immune systems, they tend to get more colds. That's why you'll often see a person with Down syndrome mouth breathing. Or drooling.

"You know, it's not a bad thing," Becky said. "I've worked with kids with Down syndrome, and they're some of the sweetest, most loving people I've ever met."

Optical components are carefully engineered from semi-transparent material, and are used to transmit or reflect light. Transmissive optical components include lenses, beamsplitters, windows, optical flats, prisms, windows, optical flats, wave plates and fiber optics. Reflectives include mirrors and retroreflectors.

A filter transmits certain wavelengths of light while absorbing or reflecting others. We manufacture long pass, short pass, and band pass filters, as well as UV blocking filters and both cold and hot mirrors.

Christopher Fairman, a professor at Ohio State's law school, literally wrote the book on the word fuck. His book, Fuck, is a historical, political and legal account of how the word became taboo—and why, in his view, it shouldn't be.

Rush Limbaugh said he found nothing wrong with "calling a bunch of people who are retards, retards," and Palin rushed to his defense, saying Limbaugh had used the word satirically.

Are we raising humanitarians or wusses? I asked myself silently, kissing the top of her head. Pretty soon, there won't be any words left.

They lived in a small apartment complex—think Melrose Place but not as swanky—and there was a giant gong by the pool. To get my mom's attention, someone banged on the gong. It scared the crap out of her; she swears that's when her labor began, though to this day she's not sure whether to blame the candy corn or the gong.

"The words we use in common language—imbecile, idiot, retard—these are medical terms developed around the turn of the last century to classify people with intellectual differences according to their IQ," Shriver said. "All of a sudden we get classifications, we get labels. They are quite horrible. And the labels lead to this idea that people are somehow lower and lower in the value chain…and become more and more desirable to get rid of."

We also carry multipart lenses. Achromatic doublet lenses are the best choice for focus on-axis, as they give minimal spherical aberration as well as color correction. Using an achromatic doublet lens will also give you a much smaller focal spot than if you had used singlets.

Frankly, it seemed like an appropriate reaction to me. But her response obviously haunted Laurie, because later that day, I got an email:

Shanghai Optics manufactures a wide variety of prism for different optical applications. Some of our most popular prisms include the right angle prism (used to bend light at a ninety degree angle), the dove prism, which rotates an image, and the roof prism, which can both invert an image and deflect light by ninety degrees.

What are you supposed to say when one of your best friends calls and tells you that her baby has Down syndrome? I still don't know. I definitely didn't know when Sophie was born.

I can live with that more easily than intellectually disabled—I don't like either of those words. Plus, I wondered, how long was it going to be before kids were calling each other "cog" on the playground?

"I sympathize with the effort," Fairman said. "It's not that I've come to praise the word 'retard'; I just don't think we should bury it. If the history of offensive terms in America shows anything, it is that words themselves are not the culprit; the meaning we attach to them is, and such meanings change dramatically over time and across communities."

A singlet lens is formed from a single piece of optical materials but may take any of a number of different shapes or sizes. The basic shapes of these optical components includes:

Hey, if I can't say "retarded," then neither can you. And neither should you. As Sophie's mom, there's so much I can't do to make the world more accepting—but I can make damn sure you quit using that fucking word.

A best-form lens is considered to be the shape which minimizes spherical aberration. The best-form lens for your application depends on several factors, primarily the conjugate ratio of the system and the index of refraction of the lens material.

A symmetric biconvex lens, with both sides bulging outward, is best form for imaging at unit magnification, where the distance to the object is the same as the image distance. For any material index and wavelength the coma, distortion and lateral chromatic aberration will cancel each other out at this unit magnification.

He made a good case, mentioning how mental retardation was actually meant to supplant imbecile, moron, and idiot—in a good way. And he took issue with Palin's comparison of retard to the word nigger.

At the time Sophie was born, Laurie was putting the final touches on her third book of essays. She actually went through that book proof, page by page, and took out the word retarded every time it appeared.

I just knew that Down syndrome was part of the list of things you don't want your kid to have—right up there with spina bifida and Tay-Sachs—and that my unborn kid had a 1-in-214 chance of getting it, according to this doctor.

My mom loves to tell my birth story. As she gets older, Sophie asks to hear it (along with her own birth story, and Annabelle's) over and over, so I know it well.

In any case, the R-word train left the station without me. Before I could decide how I really felt about it, there were campaigns everywhere to get rid of it completely.

I don't remember ever using the word "retarded" as a pejorative, but I know I must have, because years after I stopped, upon the occasion of Sophie's diagnosis, I would still find it on the tip of my tongue, feel myself craving it like a cigarette.

As a parent of a kid with Down syndrome, I have naming issues aside from how Sophie's IQ is addressed. How should we refer to a person with her genetic condition? J. Langdon Down came up with the term mongolism, because he believed the condition he'd identified was marked by features similar to those of the Mongol people, and because these people he was working with were slower mentally, he believed this to be sign of racial regression.

Of all the words used to describe people who are differently abled, retarded currently tops society's list as most offensive. That was not always the case. The word retarded has a slang-free history. For a long time, it simply meant slow.

Not long after that email, Laurie came to the house with two Baby Lulu outfits (the expensive ones, not the kind you can buy at Costco) and an apple Danish from the best bakery in Phoenix. She also gave me another gift—my favorite baby gift of all.

The terms idiot and imbecile are no longer formally used. But mental retardation remained an acceptable medical term until very recently. And early on, I routinely used mentally retarded to describe Sophie's medical condition.
