In almost every scientific paper that describes proteins you’ll find Duke biochemist Jane Richardson’s handiwork. The images, commonly referred to as “ribbon diagrams,” are basic to the language of protein science. Ranging in likeness from a flapping kite tail to a tight coil of crimped gift ribbon, these carefully etched diagrams invented by Richardson have served for many years as a primary way that scientists can describe what they see in their data.

As the elegance and complexity of proteins became more evident, scientists needed something better than wire models to articulate the subtleties they were identifying, especially in print journals. Several people had published schematic drawings of individual proteins, but each used different conventions and viewpoints. For a major review article comparing folds and details of all the known structures, Jane Richardson needed to develop a good, consistent system. She picked up a pencil and began to try drawing smooth ribbons over the atoms in early, crude computer-graphics printouts. It was promising, but hard to correctly convey the proteins in three dimensions.

“I’m not an artist and I’m not very good at drawing anything else,” she said. “It took a very long time to figure this out, how you can really show the 3D relationships on a 2D page, and also keep them accurate to the experimental atom coordinates.”

So of course both of these are slight simplifications, but what is the connection between the two? If the earth is basically a circle, is an ellipse just a parabola stretched around a circle? Is a parabola just an approximation of a tiny part of an ellipse? How high do you have to be before you change your calculations of a trajectory?

The Math ain't mathing.

I'm not really sure how to ask this because my knowledge is pretty limited. Any basic answers or links will be much appreciated.

I have a number of self hosted services on my home PC. I'd like to be able to access them safely over the public Internet. There are a couple of reasons for this. There is an online calendar scheduling service I would like to have access to my caldav/carddav setup. I'd also like to set up Nextcloud, which seems more or less require https. I am using http connections secured through Tailscale at the moment.

I own a domain through an old Squarespace account that I would like to use. I currently have zero knowledge or understanding of how to route my self hosted services through the domain that I own, or even if that's the correct way to set it up. Is there a guide that explains step by step for beginners how to access my home setup through the domain that I own? Should I move the domain from Squarespace to another provider that is better equipped for this type of setup?

Is this a bad idea for someone without much experience in networking in general?

Some posts in communities I follow are quite long. I don't mind their presence, but they are not always relevant to me and result in unnecessary scrolling to pass essay-length posts.

An option to automatically collapse posts longer than, say, 10 lines would be a nice bonus feature to have.

Anyone else agree?

Authorities say more than 20 girls are still unaccounted for at Camp Mystic in Kerr County, Texas, where the Guadalupe River rose more than 20 feet in less than two hours during torrential rains that triggered flash flooding in parts of the state yesterday.

At least 27 people, including nine children, have died in the flooding, according to local officials. The families of three campers have confirmed their deaths to CNN.

Copyright holders hire services that use bots to monitor file-sharing networks and send ISPs millions of notices a year alleging infringement by someone at a particular IP address, Cox told the Supreme Court. Cox said that ISPs "have no way of verifying whether a bot-generated notice is accurate" and that even if the notices are accurate, terminating an account would punish every user in a household where only one person may have illegally downloaded copyrighted files.

There have been a number of Scientific discoveries that seemed to be purely scientific curiosities that later turned out to be incredibly useful. Hertz famously commented about the discovery of radio waves: “I do not think that the wireless waves I have discovered will have any practical application.”

Are there examples like this in math as well? What is the most interesting "pure math" discovery that proved to be useful in solving a real-world problem?

The man who opened fire outside a Michigan church filled with worshippers before he was struck by a vehicle and then fatally shot by security staff had attended services there a couple of times in the last year and his mother is a member, police said.

"The Office of Cybersecurity has deemed WhatsApp a high-risk to users due to the lack of transparency in how it protects user data, absence of stored data encryption, and potential security risks involved with its use," the CAO said in an email obtained by Axios.
