The rise of freeform optics in imaging applications has led to optical systems with increased etendue, more compact volumes, and superior performance. In this presentation, Jannick Rolland, Ph.D., and Aaron Bauer, Ph.D., of the University of Rochester’s Institute of Optics will provide an overview of the methods in which systems utilizing freeform optics have been designed and the steps taken to bridge freeform design to manufacture. Examples of freeform systems from space applications to an application in the movie industry will be discussed. Part 1 of the 2021 Freeform Optics Series.

Hello everyone, I'm just looking to borrow $50 today. I can repay $60 on friday, March 19th. Cashapp is my preferred method. Thank you in advance for your help!
I don't want to step on anybody's toes here, but the amount of non-dad jokes here in this subreddit really annoys me. First of all, dad jokes CAN be NSFW, it clearly says so in the sub rules. Secondly, it doesn't automatically make it a dad joke if it's from a conversation between you and your child. Most importantly, the jokes that your CHILDREN tell YOU are not dad jokes. The point of a dad joke is that it's so cheesy only a dad who's trying to be funny would make such a joke. That's it. They are stupid plays on words, lame puns and so on. There has to be a clever pun or wordplay for it to be considered a dad joke.
Again, to all the fellow dads, I apologise if I'm sounding too harsh. But I just needed to get it off my chest.
Do your worst!
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!

Intro
Since the time of the NES and Master System, game consoles have had different processors. The seventh generation got weird though, Nintendo ended up with a slightly faster PowerPC chip, simply a faster GameCube CPU, but somehow, Sony and Microsoft had the exact same CPU?
Designing chips is a multi-year process, even back in the early 2000's, especially for something like a games console. In order to have a new console ready, you start working one the old console is in stores. Sony's father of the Playstation, Ken Kutaragi was on the case to figure out what the next Playstation would be built on.
Previous Playstations had used MIPS-based chips, but the growing power of Intel and Windows had caused the MIPS owner SGI to abandon further development. Intel was known for being inflexible with their chips, AMD was too pedestrian for our boy Ken, so who would he turn to? IBM, seemingly.
Why IBM? They were designing PowerPC chips for Apple Macs, and had provided a pretty good chip for Nintendo's GameCube. Not that the next Playstation could make do with an improved existing design, not under Ken's watch! The next Playstation would need a from-scratch CPU, a CPU that would rule the world! Televisions, servers, the best game console! That's how big this design was going to be.
STI Alliance
Kutaragi managed to convince Toshiba to join in on this party, so the STI (Sony, Toshiba, IBM) alliance was formed. They would design a next generation chip that would make Intel weep! Now, if IBM could only figure out what team would built the chip...
At the time, IBM had two processor design teams for PowerPC processors, server and microelectrics. The server team built humongous processors that sucked down tons of power and put out tons of heat, not good for a game console. The microelectrics team was experienced in power-efficient designs, but were lower profile in IBM than the server team.
As the contract was a $400 million zinger, the server and microelectrics divisions went back and forth about who would be the designer. But the server team lost, they just didn't have the necessary experience in power-efficient designs. The PS3 processor would be headed by the Austin IBM office headed by the microelectrics division.
Originally, each company in the alliance was intended to contribute 1/3 of the engineers, but Sony and Toshiba engineers were needed to deliver other projects, and IBM ended up with plenty of available eng

This post is inspired by another one on this sub last week, where this list from the totally unbiased source Dairy MAX was posted along with the claim that any vegan who uses products on this list is a hypocrite as no alternatives for animal by-products in these products exist and that we will always be reliant on animals for these products. So, here is my investigation into animal-free alternatives for every product on this list.
Generally, these products were less "these products simply cannot be made without animals" and more "well, sometimes they contain the chemical that might be animal-derived, but it's really hard to know."
(Disclaimer: Obviously veganism is concerned with doing "as much as is possible and practicable" to avoid contribution to animal exploitation, so even if you can't guarantee that your life hasn't involved any products made with animal by-products in a society where such (by-)products are ubiquitous, this would not invalidate being vegan. This is especially true where medications are concerned. As I see it from an ethical view, the main goal should be the ending of the industries that are the main source of animal suffering, then we can tackle the issue of minute by-product use in other products. Especially since if a decline/end in consumption of the animal non-by-products would force companies to do research into alternatives to them, since it is not economically feasible to raise cattle just for the collagen/gelatin/etc.)
Household Goods
Candles: Most candles nowadays are made from paraffin wax, beeswax (the main non-vegan option), or plant waxes like soy, palm, or carnauba. Tallow used to be used, but not any more. See also VeganFriendly.
Cellophane: "Cellophane™ is a polymeric cellulose film made from the cellulose from wood, cotton, hemp, or other sources." (source). The more general plastic wrap is made, unsurprisingly, from plastics like PVC. None of the pages I saw when Googling this one mentioned animal fats.
Ceramics: Obviously bone china isn't vegan as it contains bo

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.

This morning, my 4 year old daughter.
Daughter: I'm hungry
Me: nerves building, smile widening
Me: Hi hungry, I'm dad.
She had no idea what was going on but I finally did it.
Thank you all for listening.
There hasn't been a post all year!
You may remember that three years ago, I made this headcanon regarding a nationalized American rail network under the Progressive Party. Since then, I've revised it greatly to make it a bit more realistic.
One thing that doesn't change is that the 2ACW is still averted (I'm mainly going off the Kaiserredux mod here) after George Norris won the 1936 election and righted the boat.
Anywho, let's begin:
Prelude
With Huey Long and Jack Reed satisfied by a relief bill and William H. Murray, leader of the Old Democratic Party, arrested, President Norris turned to other matters. Chief among them was reviewing the United States Army, namely the debate over doctrine; ultimately, Leslie McNair's reforms involving massed artillery strikes was chosen.
Among Norris' priorities, however, was completely restructuring American society. He termed his reforms "capitalism with socialist characteristics", a fancy way of saying "social democracy". His biggest achievement was abolishing the archaic Electoral College, with all future presidential elections decided by the popular vote. But what usually gets lost among his achievements is the reorganization of the entire government.
One of the lesser examples was renaming the various departments to "administrations". For example, the United States Department of Justice (DOJ) was renamed the "United States Justice Administration" (USJA), the United States Department of Agriculture (USDA) was renamed the "United States Agricultural Administration" (USAA, not to be confused with the United Services Automobile Association), and the United States Department of Transportation (DOT) was renamed the "United States Transit Administration" (USTA).
Formation of the United States Transit Administration
The formation of the USTA coincided with the nationalization of almost all forms of transportation in the United States. Each sub-administration was as follows:
- United States Highway Administration (USHA), responsible for the highway system
- United States Bus Administration (USBA), responsible for all bus services, both city and long-distance
- United States Mass Transit Administration (USMTA), responsible for all streetcar and subway operations
- United States Shipping Administration (USSA), responsible for all trucking and maritime trade, both ocean and river; this included nationalizing United States Lines and Matson, and all
It’s pronounced “Noel.”
