The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must be legitimate questions. All post titles must include a question.

Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding META posts and joke questions.
Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.

If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.
Rule 7- You can't intentionally annoy, mock, or harass other members.
If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.

Teflon. Goddamned Teflon. Did your podcast mention Dr. Kenneth Berry? (No, not the nutrition quack. The other one.)
Dr. Roy J. Plunkett gets all the credit for the discovery of Teflon and it's true that his name appears on the patent for the process for creating the actual material. As it was the dry powered precipitate wasn't terribly useful as a consumer product and mostly only saw use being pressed into solid forms for making highly corrosion resistant gaskets and seals for e.g. nuclear equipment.
Dr. Kenneth Berry's picture is not hanging in the hallways in DuPont's offices. His name appears on no plaque. He's not mentioned in the Wikipedia article about Teflon. When it comes to DuPont's puff pieces and their official history, you'll notice that in the gap between the accidental discovery of that weird slippery white powder and its advent as a consumer product there is inevitably some dismissive handwaving and use of the passive voice. Oh, "it was discovered that..." and "DuPont engineers determined that..."
They don't mention that Dr. Kenneth Berry was the inventor of the solution form of Teflon. He figured out how to dissolve and suspend it in liquid, and by extension how to actually apply it to surfaces in a useful manner. He did not invent the pan, but he was instrumental in figuring out how it could be done. And it was Dr. Berry who ate the first fried egg cooked on a Teflon surface — not Marc Grégoire. It's quite clear. Dr. Berry's patent was applied for and granted in 1951. Grégoire's, 1954.
DuPont doesn't mention this because Dr. Berry also knew damn well what nasty chemicals DuPont was using to produce Teflon, and to some degree he knew where and how they were dumping them. He documented all of this he could, stored it in a bank deposit box, and wrote it into his will that these documents were to be released to the public when he died in 2008. In retaliation for this, DuPont memory holed him. He is persona non grata there, even in death.
I know this because he told me so. Dr. Berry lived in the town I grew up in. It's not in whole thanks to him that we know the full story of the deeply evil things DuPont has done, but it is certainly in part. I was knee high to a grasshopper at the time so the significance of this was surely lost on me. I know, however, why my mother was so insistent that we never owned any Teflon pans.
Dr. Kenneth Berry: Lived, invented, developed a conscience, once shot my stuck kite out of a tree with his shotgun, tattled on DuPont, died.
