Czochralski Process Puns

I was reading the wiki page for the Czochralski process, and I had some questions about it.

1. Is the "seed crystal" really small to make sure it's a single crystal? I would imagine a poly-crystalline seed wouldn't make a single large crystal, and would have grain boundaries.

2. Is the molten material cooled as the seed is rotated and raised? What exactly are the "temperature gradients" being controlled? Is it hot outside and the rod is cooled to make the molten material solidify on it?

3. A lot of the material refers to the Czochralski process in the case of silicon to make silicon wafers, would it differ for making single crystals of other materials, such as silver?

4. How on Earth do you pronounce Czochralski?

I know this isn't a practical question like a lot of discussions in this sub, so just let me know if I should head over to /r/askscience or something.

#Report on Dutch diaspora activities in the Fens

###An attempt to demystify and analyze the secluded Dutch diaspora, and their activities in the Fens

March 1st, 2041
by Seamus Pegg

  > SUMMARY - The Dutch diaspora following the Fall of the Netherlands has largely settled in the Fens. The national trauma of losing their homeland has driven them to a form of extreme self-reliance and doomsday prepping. They have developed biovats to produce their food and other organic materials independent from imports.

##0. Foreword

Analyzing the Dutch diaspora in Ireland is a difficult subject. They have formed a tight knit and tight lipped society of their own, away from the prying eyes of outsiders. Their concern is understandable when recognizing their national trauma of having lost their homeland of the Netherlands.

Opinions on the Irish government are generally positive, as one might have a positive opinion of their neighbours down the road. Although they appear understanding of Ireland having been on vacation during the Downfall War, they do not have much interest in integrating into larger society. This has made data collection difficult, as the Dutch have gone to great lengths to frustrate any such activities in the name of “national security”. Their national security refers to that of the Dutch settlement in the Fens, which is almost an information black hole.

As such this report represents a “best guess”, and does not adhere to Chatham House’ regular standards for trustworthiness. Recognizing the distinct lack of literature available on the matter, Chatham House has decided to go ahead and release the report anyway, for private eyes only.

By Dutch demand, certain sections have been censored to protect their “national security”. At times, the censored text may appear nonsensical as the information void that is the Fens, but this is the way the Dutch do things.

I'm surprised it hasn't decade.

For context I'm a Refuse Driver (Garbage man) & today I was on food waste. After I'd tipped I was checking the wagon for any defects when I spotted a lone pea balanced on the lifts.

I said "hey look, an escaPEA"

No one near me but it didn't half make me laugh for a good hour or so!

Edit: I can't believe how much this has blown up. Thank you everyone I've had a blast reading through the replies 😂

It really does, I swear!

The GGGQEP is in two parts – the GGG and the QEP – and it can be framed, in the most simplified way, as follows:

Gadolinium Gallium Garnet – or GGG in short – has a number of exotic properties that make it the perfect candidate for the next level of massive data storage. Firstly, it is crystalline in nature, and its ingots can easily be grown through Czochralski’s seeding. Secondly, it has a cubic lattice, and hence any 3D laser-writing upon it, and subsequent reads, can be conducted with utmost accuracy. Thirdly, its crystal hardness, as expressed on the Mohs scale, falls somewhere between that of Orthoclase Feldspar, and Topaz – which is neither too hard to economically process in a large scale, nor too soft to risk data compromise due to frequent,and prolonged, read-write cycles. And lastly, GGG has already been used in a related field – the magnetic bubble memory field – as a substrate for the magnetic-optical films. Hence, its magnetic and optical properties, including its refractive index, are well documented.

Now for some elementary, but important, figures. The molecular formula of GGG is Gd3Ga5O12. One mole of GGG (i.e. 6.023 * 1023 molecules) has a weight of 872.9118 grams which, at a density of 7.08g/cm3,evaluates to a mole volume of 123.29cm3. If this was crafted into a perfect cube, the sides would be exactly 4.977095cm long. For the sake of simplicity, this can be rounded off to 5cm. So a GGG cube of precisely 5cm5cm5cm would have approximately one mole of the molecules. Through a rather extensive extrapolation, it can be worked out that GGG molecules hold data (in bits) equivalent to about 12.5% of the total number of molecules present. Hence, one mole can hold about 7.52*1022 bits of data, which can further be evaluated to 8153.20034 exabytes of data. Each exabyte is equivalent to one billion gigabytes. For the sake of perspective, the entireindexed internet, at the moment, has about 700 exabytes of data. So with a single GGG cube measuring 5cm per side, more than 11 internets, at present size, can be comfortably accommodated.

Quantum Electronic Processing – or QEP in short – is an area still fraught with all manner of cognitive and execution hurdles. Cognitive in the sense that the central idea in it is pretty counter-intuitive. And execution in the sense that once the idea is grasped, the implementation still raises some major problems. But there is a promising solution, and hence both the cognitive and the executive hurdles will

Dad jokes are supposed to be jokes you can tell a kid and they will understand it and find it funny.

This sub is mostly just NSFW puns now.

If it needs a NSFW tag it's not a dad joke. There should just be a NSFW puns subreddit for that.

Edit* I'm not replying any longer and turning off notifications but to all those that say "no one cares", there sure are a lot of you arguing about it. Maybe I'm wrong but you people don't need to be rude about it. If you really don't care, don't comment.

When I got home, they were still there.

Following the bounty of June birthstones (pearl, moonstone, and alexandrite), you might think that July was a bit slighted by its singular, monochromatic birthstone. Yet ruby is one of the most coveted and valuable of all gemstones, beloved for thousands of years and across nearly every culture. In Sanskrit it is even known as ratnaraj, or "King of Precious Stones." But the history of ruby is rooted in misunderstandings and subterfuge, a legacy that the gem still struggles with today.

via GIA.edu

Long before the development of the science of gemology, gems were typically identified by color. Thus, green gemstones were emeralds, blue gemstones were sapphires, and red gemstones were rubies. As science advanced and gemologists developed more comprehensive tests for separating gemstones, they realized that sapphire and ruby were actually both members of the corundum species. Corundum is allochromatic, which means that the factors that cause color in the gem are not intrinsic to its chemical composition. As a result, in its purest form (Al2O3) corundum is colorless, and the presence of trace elements in certain concentrations create a rainbow of colors. Blue is considered the "standard" color of sapphire by the industry, while all other hues of corundum besides ruby are designated as "fancy" sapphires.

But then why is ruby set apart? The simplest answer is marketing. After centuries of referring to this variety of corundum as "ruby," the color red and ruby are inextricably linked in the public mind. And as red is the most valuable of all corundum hues, it made sense to keep it in its own unique category. However, the line between pink and purple sapphire and ruby is a controversial topic all its own.

The chromophore, or color-causing element, that creates the red of ruby is chromium. The more chromium is present in the gem, the stronger the red color. Chromium can also create the vibrant red [fluorescence](https://
