79th World Science Fiction Convention (Discon III)

79th World Science Fiction Convention DC 2021

The 79th World Science Fiction Convention (Discon III) is being held in DC in three days, running from 12/14/2021 through 12/19/2021. They had a long struggle deciding between real & virtual. They settled on real but with lots of virtual bits. I’m just pleased they decided to go forward. Full schedule is now online. Note the web page is a bit fragile & needs sometimes a bit of coaxing.

I’m giving two short talks and serving as panelist on three panels. Because of space problems, many of the talks are sharing an hour. Both my talks are 25 minutes:

Artificial Intelligence: Past, Present, and Futures

From neural nets and genetic algorithms to facial recognition and deep fakes, artificial intelligence (AI) is everywhere today. What exactly do we mean by AI? How did AI get where it is today? What role will it play in our lives? What are the benefits and risks of AI? And when will we have real AI?

7PM Thursday December 16th, 2021. This is the top of the hour so should start at 7PM. Slides up on slideshare.

The Quantum Internet:  Hype or the Next Step?

What do we mean by the quantum internet? Why do we need more than just quantum computing? What are quantum cryptography, quantum key distribution, quantum sensors? How are these concepts entangled? What are the advantages of the quantum internet? key problems? Who will get to use it? And do we have just a bunch of interesting technologies that all have quantum in their name or can the whole be more than the sum of its parts?

10AM Sunday December 19th, 2021. This is the 2nd half of the hour so will probably start about 10:25AM. Slides up on slideshare.

And I’m doing three panels (all 50 minutes):

The State of Machine Learning

An artificial intelligence does not necessarily have to think like a human being. How do current AIs approach questions of cognition and meaningful analysis? What are other ways that an intelligent AI might perceive and understand the world?

Notes for participants: Examples. AI as a personal assistant, AI as a social benefit, AI as a threat, making sense of big data, autonomous vehicles, neural networks, automated facial recognition, behavioral analysis, racial bias in training data. The term xenosapience is used in some sf non AIs that do not think like people.

Balancing Story and Scientific Authenticity

Many readers love real science, or just the appearance of real science, in their science fiction. It is no small challenge to create compelling literature that also triggers a scientific sense of wonder. Panelists discuss how to do it right.

I’m moderating this & much looking forward to it. I have a lot of questions for the panelists:

  • How can getting the science right make the story better?
  • What are some of the best examples of getting the science right? Hal Clement — Mission of Gravity, Uncommon Sense, … — comes to mind of course, many others.
  • How to give readers the right amount of explanation? Obviously we want a bit more scientific detail in The Martian than in Lucky Starr and the Pirates of the Asteroids! My own feeling is that Arthur Clarke was the all-time master of balancing science & wonder. Your selections for this?
  • What are some examples where the science was just so awful that it interfered with the story? Or the story died the death of painful exposition? (Venus Equilateral comes to mind; feel free to disagree of course!)
  • What are some of your own stories where you think, all modesty aside, that you got the science just about right! And what were some places where you had to do a bit of work to achieve the best balance?
  • What advice would you give a new writer on how to handle the science?
  • What advice would you give a reader on what to look for in a story’s treatment of science?
  • What differences are there in way you would handle different sciences? we often break the sciences down into soft and hard, is that valid?
  • How to handle alien sciences?
  • How do you like to prep the science?

11:30AM Thursday, December 16th, 2021. Virtual

International Space Program

Americans may not hear much about it, but there’s a thriving culture of space exploration and science outside of the United States. Come hear about some of the notable missions, developments, and discoveries of 2020 and 2021.

The Quantum Internet and: Cthulhu Now!, Don’t get your time machine in a twist, and Warped Plotting

Google conducts largest chemical simulation on a quantum computer to date
Google’s Sycamore Quantum Computer

This year’s Philcon is going forward in person, in spite of Covid! It runs from Friday afternoon (11/19/2021) through Sunday afternoon (11/21/2021). Jabs & masks mandatory, but it will be great to see old friends in person. And make a few new as well. My science talk is:

The Quantum Internet: Hype or the next step

What do we mean by the quantum internet? Why do we need more than just quantum computing? What are quantum cryptography, quantum key distribution, quantum sensors? How are these concepts entangled? What are the advantages of the quantum internet? key problems? Who will get to use it? And do we have just a bunch of interesting tech that all have quantum in their name or can the whole be more than the sum of its parts?

This will be 1 pm Saturday November 20th at Philcon 2021

I did this at this year’s Capclave. Went well: some pretty deep questions from the audience at the end, always a good sign. I’ve updated — quantum computing does not stand still! — and looking forward to presenting in a few days. The picture is of Google’s Sycamore Quantum Computer, which recently achieved “Quantum Supremacy”. I will explain what that means!

I’m doing three panels as well:

The Post-Lovecraftian Cthulhu

How have HP Lovecraft’s ideas evolved in the hands of subsequent writers?

At this point, post-Lovecraftian Cthulhu is 99+% of Cthulhu. There are a lot of interesting directions here: from more mythos (Derleth for instance), more grim humor (Stross), high tech reboots (Delta Green), and a deeper (pun intended) take on Lovecraft’s racism (Lovecraft Country, Ballad of Black Tom). And we have uses of Cthulhu in music, film & TV (of course!), theater, and even in real science (the elongated dark region on Pluto nee Yuggoth called Cthulhu Macula!) if we are willing to include songwriters, playwrights, & scientists as part of the dark horde of subsequent writers.

This with Darrell Schweitzer (my co-editor on Tales From the Miskatonic University Library) and Stephanie Burke (writer, cosplayer, and a remarkable presence). I proposed the topic so have been unable to avoid the scourage of moderation.

At 10pm Friday, 11/19/2021

A Beginner’s Guide to Time Travel Paradoxes

You know not to remove a major historical figure, hand Thomas Edison a cell phone, or kill your grandfather. But is it even possible to travel into the past without changing anything?  So you go back to Chicago in 1920, and eat a hamburger in a diner. But, unbeknownst to you, that hamburger was destined to sit for six hours, spoil, and sicken someone else, who misses an important appointment, and… there goes the timestream. Would nature have a way of correcting this?

This with Michael Ventrella, George W. Young, and Russell Handelmann. Michael is currently editing a time travel anthology and is also moderating the panel. Michael’s a lot of fun; the other two I look forward to meeting.

At 2pm Saturday, 11/20/2021

Parsecs, Light Years, and the Speed of Plot

Warp?  Hyperspace?  Ion propulsion?  Improbability drive?  Is it necessary to sacrifice accuracy to maintain pacing?  Our panelists science the heck out of “velocity equals distance divided by time” as used in fiction.

This with Tobias F. Cabral (moderator), Anastasia Klimchynskaya, Tom Purdom. All familiar & valued co-panelists!

At 4pm Saturday, 11/20/2021

Quantum internet at Capclave 2021

Somewhat surprisingly, even tho the Washington DC Science Fiction community is hosting this year’s Worldcon, they are still doing their regular annual convention as well, Capclave 2021. Kudos for courage! And it is inperson as well (proof of vaccination required).

I’m doing a talk on the Quantum Internet this year at Capclave. I moderated a panel on the quantum internet at the most recent Balticon. Panel went well (video of the panel is up on youtube) thanks to my two fellow panelists Kevin Roche and Anne Gray. This is a great subject, so I figured a dedicated talk on this would be fun & helpful to people. Hence:

The Quantum Internet: Hype or the next step

What do we mean by the quantum internet? Why do we need more than just quantum computing? What are quantum cryptography, quantum key distribution, quantum sensors? How are these concepts entangled? What are the advantages of the quantum internet? key problems? Who will get to use it? And do we have just a bunch of interesting tech that all have quantum in their name or can the whole be more than the sum of its parts?

This will be 4pm Saturday October 2nd, 2021 at Capclave

I’m doing two panels as well:

Horrors found in the Editor’s Slush

I’ve copyrighted this story so you cannot steal it and publish it under your name. “And their names were Adam and Eve.” The manuscript written in crayon. Threats if the editor rejects a story. Considering that writers want their stories to be published, they do seem to do everything possible to discourage editors. What are some of the horrors you found in submissions? What should new writers know to avoid?

This with Walt BoyesNeil ClarkeDina Leacock

At 8pm Friday October 1st, 2021 at Capclave

A Century of Robots

The play RUR (Rossum’s Universal Robots) premiered in January 1921. This play was the first to use the word robot for a scientifically created mechanical worker. Why has the concept of robots been so popular? How have robots evolved in fiction?

This with Jennifer PoveyMichael SwanwickJoy Ward

Can we get certain about uncertainty in time?

Einstein takes some time out for time

There is a decent chance that quantum mechanics applies in time in the same way it does in the three space dimensions. I say decent because Einstein’s relativity says we have to treat time like a space dimension. So if quantum mechanics applies in space — and it does! — then it has to apply in time as well.

And since in quantum mechanics all measurements are uncertain about position of an object in space, they therefore have to be uncertain about its position in time as well. Hey, blame Einstein, not me!

The effects are expected of order attoseconds. Now one attosecond is to a second as a second is to the age of the universe: not very long. But with current tech we can actually see times this short.

So we can now tell if the position of a particle is uncertain in time. It’s “now” might be really a bit fuzzy: with a bit of “future” and a bit of “past” mixed in.

I’ve just had published a paper on the specifics of how we might measure the effects of this “Does the Heisenberg uncertainty principle apply along the time dimension?“. This is in the Conference Proceedings of the International Association for Relativistic Dynamics, which is focused on following up on some ideas first suggested by Feynman & by Stückelberg.

I’m working on getting some experimentalists interested in this & have started the next paper in the series “Time Dispersion in Quantum Electrodynamics” to help them crank out estimates effects for various experimental configurations. Much stoked!

It may be more than a few attoseconds before the first results are in, but at this point it should be just a matter of time! And it might be very practical, with real-world applications in biophysics, attosecond-scale chemistry, and quantum computing.

For the record, the abstract of the paper is:

Does the Heisenberg uncertainty principle (HUP) apply along the time dimension in the same way it applies along the three space dimensions? Relativity says it should; current practice says no. With recent advances in measurement at the attosecond scale it is now possible to decide this question experimentally.

The most direct test is to measure the time-of-arrival of a quantum particle: if the HUP applies in time, then the dispersion in the time-of-arrival will be measurably increased.

We develop an appropriate metric of time-of-arrival in the standard case; extend this to include the case where there is uncertainty in time; then compare. There is – as expected – increased uncertainty in the time-of-arrival if the HUP applies along the time axis. The results are fully constrained by Lorentz covariance, therefore uniquely defined, therefore falsifiable.

So we have an experimental question on our hands. Any definite resolution would have significant implications with respect to the role of time in quantum mechanics and relativity. A positive result would also have significant practical applications in the areas of quantum communication, attosecond physics (e.g. protein folding), and quantum computing.

Artificial intelligence, the quantum internet, and life and/or death

The 2021 Baltimore Science Fiction Convention (Balticon) runs this coming weekend. Virtual but real, if you get my drift. Convention is free; the programming looks very strong. Poke around & check off the interesting ones: I had great trouble keeping my choices down to one per time slot.

And, Balticon has recorded all of the talks: I’ve linked each talk to its video.

For my Balticon talk I’m doing:

Hands as seen by an artificial intelligence.
The Hands of AI

Artificial Intelligence: Past, Present, and Futures: Saturday, 2:30pm

From neural nets and genetic algorithms to facial recognition and deep fakes, artificial intelligence (AI) is everywhere today. What exactly do we mean by AI and how did it get where it is today? What are the benefits and risks of AI and how should we manage it going forwards?

Fast moving & fun topic!

Ethics and Robotics: Friday, 4pm

Isaac Asimov’s Three Laws formed one of the earliest ethics systems for robots and artificially-created beings, but aren’t necessarily accurate or complete. A hundred years after Asimov’s birth, what approaches are being taken in the practical development of robots? What is “real AI” and how far away are we from it?

With Anne Gray aka netmouse (moderator), Aaron M. Roth and Marie Vibbert

The Quantum Internet: Hype or the Next Step? Saturday, 7pm

What do we mean by the quantum internet? What are quantum cryptography, quantum key distribution, quantum sensors, and linked quantum computers? What are the advantages and key problems? Who will get to use it? And do we have just a bunch of interesting tech that all have quantum in their name or can the whole be more than the sum of the parts?

I’m moderating this one with Anne Gray and Kevin Roche (who is the quantum computing evangelist at IBM).

From “Mostly Dead” to Alive and Back Again: Sunday, 10pm

How is it that something like the coronavirus can be completely inert one moment and then spawning millions of copies of itself the next? How did intracellular obligate parasites — organisms that can’t survive without a host — manage to evolve into existence in the first place? What of transposons (jumping genes), viroids (the smallest infectious pathogens known), and the dreaded “giant” viruses? Join us as we dart back and forth across the line that separates life & death in biology!

I’m moderating this one as well, with the panelists: Dr. Jim Prego, Doug Dluzen, Anna Kashina, Pam Garrettson.

Does the Heisenberg uncertainty principle apply along the time dimension?

Does the Heisenberg uncertainty principle (HUP) apply along the time dimension in the same way it applies along the three space dimensions? Relativity says it should; current practice says no. With recent advances in measurement at the attosecond scale it is now possible to decide this question experimentally.

  • The Mechanical Turk — popular chess playing fake (18th century)
  • Tik-Tok — Wizard of Oz
  • Robot Maria — Metropolis
  • Joe (transparent robot) — The Proud Robot
  • Roy Batty (replicant) – Bladerunner

2020 Philadelphia Science Fiction aka Philcon

Philcon runs from about noon this coming Friday (11/20/2020) till early evening Sunday (11/22/2020). It is, inevitably, virtual this year. With that said, they are going to a lot of trouble to make it as live & immediate as possible. And are clearly much helped by the benefit of earlier virtual conferences this year. For instance, the program participants were invited to training sessions to check out their setups & make sure they knew how to present on Zoom & Discord. I found mine helpful. Thanks Syd Weinstein & crew!

I have my schedule as well:

 Joy in SciencePlaza 1Science & TechnologyPanelFri 8:30 PM

And have Robert Hranek (who has already scared me with his level of preparation), Premee Mohammed (who has scared me with her Lovecraftian Beneath the Rising and who is basically the advance team for Mars), and Tobias Cabral (who I’ve shared many panels with & who is not at all scary — meaning no offense!) to put questions to!

Artificial Intelligence: Past, Present, & Futures

I will be presenting a talk on Artificial Intelligence: Past, Present, & Futures at the 2020 Capclave (virtual). That’s this coming Sunday from 1:30 to 2:25. Capclave is running Saturday & Sunday.

Virtual, yes, but they have rather a good line up of former guests of honor, kaffleklatsches, talks, panels, and so on. I’m looking forward. As to my talk:

Artificial Intelligence: Past, Present, Futures (Ends at: 2:25 pm)
Participants: John Ashmead (M)
From Oz’s Tik-Tok to the Mechanical Turk, from Neural Nets & Genetic Algorithms to Chess & StarCraft, from fighting the Coronavirus to flying Killer Drones, from Facial Recognition to Fakes, Deep Fakes, & Anti-Fakes, Artificial Intelligence (AI) is everywhere today. How did it start? What do we mean by AI? What are the basic AI techniques? How is it being used? What are the benefits? risks? and how should we manage AI going forwards?

The Elephant Versus the Bug

Debugging with PostgreSQL -- the Elephant takes on the Bug

Depending on the project, debugging can take 50 to 90% of development time. But it usually gets less than 10% of the press. PostgreSQL has great tools for debugging, but they are most effective when deployed as part of an overall strategy.

Ten days from now I’m doing a webinar on how best to do this. That’s 1pm, July 29th, 2020. You can register here.

It’s a fun talk: I focus on the key ideas, give a few good examples, have a quick quiz “There are three bugs on this slide: you have the next two slides to find them!” and then finish with some of my favorite debugging references: selected as particularly readable & practical.

[Update: the talk was given as planned. Thanks to Lindsay Hooper for great support! Video is online. And the audience of invisible Zoomers upped the number of bugs on the quiz slide from three to five!]

Last time I did this talk, my favorite piece of feedback was from Bruce Momjian, a founder of PostgreSQL and a member of the core team: Bruce said there was stuff he knew but hadn’t heard put into words, and stuff he just hadn’t seen yet.

And that’s how I hope this will be for you!

We will look at strategies for debugging PostgreSQL: how to find bugs, how to fix them, and how to keep them from happening in the first place.

We’ll look at root causes, technical tricks, and scientific strategies, and why — even if you can’t always write perfect code — it is usually a good idea to try.

We’ll hear from Bjarne Stroustrup, Sherlock Holmes, Kernighan and Ritchie, Pogo, & the experts of the PostgreSQL community.

Goal: less time debugging, more time building great tools and apps that stay up & get the job done.

If you can’t wait or just can’t make it, I have the latest version here: PDF, KeyNote, and PowerPoint, name your poison.

Update

Talk went off smoothly, about 65 or 70 attendees. The invisible Zoomers found two more bugs on the “quiz” slide! The event organizer, Lindsay Hooper of the PostgreSQL conference, did a great job setting every thing up, watching over a dry run, and giving feedback during. And she recorded and edited the webinar, so if you are interested in see the video “live”, herewith.
