flame-throwing robot dogs

Leave a reply

I was skeptical at first, but apparently there are a number of flame-throwing robot dogs that you can buy. Flame throwers have legitimate uses in agriculture, forestry, and ecological restoration, and are very lightly regulated. These seem dangerous, but then again the backpack-mounted alternatives seem very, very dangerous (basically, a backpack full of gasoline or napalm). There are links to a number of questionable videos in the article I have linked to above, but the one I link to below is an actual manufacturer of these things.

AI “coscientist”

Leave a reply

The idea of computers and robots greatly accelerating the rate of progress in chemical and drug research is not science fiction.

Autonomous chemical research with large language models

Transformer-based large language models are making significant strides in various fields, such as natural language processing1,2,3,4,5, biology6,7, chemistry8,9,10 and computer programming11,12. Here, we show the development and capabilities of Coscientist, an artificial intelligence system driven by GPT-4 that autonomously designs, plans and performs complex experiments by incorporating large language models empowered by tools such as internet and documentation search, code execution and experimental automation. Coscientist showcases its potential for accelerating research across six diverse tasks, including the successful reaction optimization of palladium-catalysed cross-couplings, while exhibiting advanced capabilities for (semi-)autonomous experimental design and execution. Our findings demonstrate the versatility, efficacy and explainability of artificial intelligence systems like Coscientist in advancing research.

It seems to me that the speed limit here is not anything imposed by the computers and robots, but your ability to measure progress and give the computers and robots feedback. With chemicals, you could tell the robots to find a combination of compounds that will do XYZ, where XYZ is something you can measure like an amount of energy or a color. With drugs, your issue could be how to test the results to see if they are working. If you test them on a computer model, your ability to measure depends on how good the computer model is. Let’s say you wanted to breed a super-intelligent mouse. There should be ways to measure the intelligence of a mouse. So you could take 100 mice test them all, find the two smartest and create a new batch of 100 embryos from the smartest male and female (or maybe at some point gender is no longer a limitation?). Now you have to wait for those 100 embryos to grow up to the point you can repeat the process. The limiting step here would be how long it takes the mice to develop to the point they can be tested. If they could somehow be tested at the embyro stage, maybe you could create a thousand generations of mouse directed mouse evolution in a matter of hours or days? Well, then, you can let the super-intelligent mice design the next round of robots.

Knightscope – for criminals who operate above the law

Leave a reply

That is a dated Knight Rider reference, for those who didn’t watch trashy but awesome TV in the 1980s. These things are operating in some parking lots in Philadelphia. Some people predict Philadelphians will destroy them in short order. But they thing is, they are basically just a camera on wheels. So if you destroy it, you are creating evidence of yourself destroying, which the owner of this thing will be motivated to use against you in court. Some people say this is dystopian, but I don’t see a huge difference between this and a plain old security camera.

I wouldn’t mind getting one to collect video evidence of whoever it is leaving dog poop on my block. And no, whoever you are, bagging it before you drop it on the ground doesn’t really excuse you. Somebody still has to pick up your feces, and if that plastic bag gets washed into a storm drain and eventually out to the ocean, the crap will biodegrade in a few hours (possibly suffocating a few nearby fish in the process) but the plastic bag will be there in 1,000 years.

bathroom cleaning robots

Leave a reply

Just a quick note on my business plan to invent bathroom cleaning robots. As soon as I invent a truly effective and inexpensive bathroom cleaning robot, everybody in the world will buy one and I will be the richest person in the world.

The Philadelphia Inquirer had a recent article called Why household robot servants are a lot harder to build than robotic vacuums and automated warehouse workers. Granted, cleaning a bathroom is really hard on a human body, especially one that is getting older. But why would you assume a robot that looks or acts like a human would be the way to do this. I picture something more like a swarm of ants that can pick up individual pieces of yuck, drop them in a pile somewhere, and then go back to their charger pad. Or maybe spiders. Too creepy? Well, just make them look like little seashells or something not creepy. Why is this so hard?

You could also approach the problem from the other end – designing bathrooms and kitchens that are more appropriate and accessible for robots. Come to think of it, bathrooms and kitchens are not all that appropriate and accessible for humans as it is. This whole thing could use a rethink. All surfaces should be completely impermeable and able to be hosed down. Instead of moving dishes from dishwashers, to sinks, to cabinets, and back again five times a day, all these things should just be one thing. You put dirty dishes in a cabinet, shut the door, open the door next morning, and you have clean dry dishes. Every dish would go in the same spot every time, and robots could handle this. Robots could also reorder peanut butter when the jar is half full, and eggs when they are half gone. For that matter, packaging could be completed redesigned to make more sense for robots as well as humans. Packaging is a big part of our environmental and waste problems in our so-called modern world.

2021: Year in Review

Leave a reply

As per usual, I’ll list out and link to the stories I chose as the most frightening, most hopeful, and most interesting each month in 2021. Then I’ll see if I have anything smart to say about how it all fits together.

Survey of the Year’s Stories and Themes

Most frightening and/or depressing stories:

  • JANUARY: A China-Taiwan military conflict is a potential start-of-World-War-III scenario. This could happen today, or this year, or never. Let’s hope for the latter. This is a near-term existential risk, but I have to break my own “rule of one” and give honorable mention to two longer-term scary things: crashing sperm counts and the climate change/fascism/genocide nexus.
  • FEBRUARY: For people who just don’t care that much about plants and animals, the elevator pitch on climate change is it is coming for our houses and it is coming for our food and water.
  • MARCH: In the U.S. upper Midwest (I don’t know if this region is better or worse than the country as a whole, or why they picked it), electric blackouts average 92 minutes per year, versus 4 minutes per year in Japan.
  • APRIL: One of the National Intelligence Council’s scenarios for 2040 involves “far-reaching changes designed to address climate change, resource depletion, and poverty following a global food catastrophe caused by climate events and environmental degradation”.
  • MAY: The Colorado River basin is drying out.
  • JUNE: For every 2 people who died of Covid-19 in the U.S. about 1 additional person died of indirect effects, such as our lack of a functioning health care system and safe streets compared to virtually all our peer countries.
  • JULY: The western-U.S. megadrought looks like it is settling in for the long haul.
  • AUGUST: The U.S. is not prepared for megadisasters. Pandemics, just to cite one example. War and climate change tipping points, just to cite two others. Solutions or at least risk mitigation measures exist, such as getting a health care system, joining the worldwide effort to deal with carbon emissions, and as for war, how about just try to avoid it?
  • SEPTEMBER: The most frightening climate change tipping points may not be the ones we hear the most about in the media (at least in my case, I was most aware of melting ice sheets in Greenland and Antarctica, collapse of ocean circulation patterns). The most damaging may be melting permafrost on land and methane hydrates underwater, both of which contain enormous amounts of methane which could set off a catastrophic and unstoppable feedback loop if released in large quantities.
  • OCTOBER: The technology (sometimes called “gain of function“) to make something like Covid-19 or something much worse in a laboratory clearly exists right now, and barriers to doing that are much lower than other types of weapons. Also, because I just couldn’t choose this month, asteroids can sneak up on us.
  • NOVEMBER: Freakonomics podcast explained that there is a strong connection between cars and violence in the United States. Because cars kill and injure people on a massive scale, they led to an expansion of police power. Police and ordinary citizens started coming into contact much more often than they had. We have no national ID system so the poor and disadvantaged often have no ID when they get stopped. Everyone has guns and everyone is jumpy. Known solutions (safe street design) and near term solutions (computer-controlled vehicles?) exist, but are we going to pursue them as a society? I guess I am feeling frightened and/or depressed today, hence my choice of category here.
  • DECEMBER: Mass migration driven by climate change-triggered disasters could be the emerging big issue for 2022 and beyond. Geopolitical instability is a likely result, not to mention enormous human suffering.

Most hopeful stories:

  • JANUARY: Computer modeling, done well, can inform decisions better than data analysis alone. An obvious statement? Well, maybe to some but it is disputed every day by others, especially staff at some government regulatory agencies I interact with.
  • FEBRUARY: It is possible that mRNA technology could cure or prevent herpes, malaria, flu, sickle cell anemia, cancer, HIV, Zika and Ebola (and obviously coronavirus). With flu and coronavirus, it may become possible to design a single shot that would protect against thousands of strains. It could also be used for nefarious purposes, and to protect against that are ideas about what a biological threat surveillance system could look like.
  • MARCH: I officially released my infrastructure plan for America, a few weeks before Joe Biden released his. None of the Sunday morning talk shows has called me to discuss so far. Unfortunately, I do not have the resources of the U.S. Treasury or Federal Reserve available to me. Of course, neither does he unless he can convince Congress to go along with at least some portion of his plans. Looking at his proposal, I think he is proposing to direct the fire hoses at the right fires (children, education, research, water, the electric grid and electric vehicles, maintenance of highways and roads, housing, and ecosystems. There is still no real planning involved, because planning needs to be done in between crises and it never is. Still, I think it is a good proposal that will pay off economically while helping real people, and I hope a substantial portion of it survives.
  • APRIL: Giant tortoises reach a state of “negligible senescense” where they simply don’t age for a long time. Humans are distant relatives of giant tortoises, so maybe we can aspire to this some day. They are not invulnerable to injury and disease.
  • MAY: An effective vaccine for malaria may be on the way. Malaria kills more children in Africa every year than Covid-19 killed people of all ages in Africa during the worst year of the pandemic. And malaria has been killing children every year for centuries and will continue long after Covid-19 is gone unless something is done.
  • JUNE: Masks, ventilation, and filtration work pretty well to prevent Covid transmission in schools. We should learn something from this and start designing much healthier schools and offices going forward. Design good ventilation and filtration into all buildings with lots of people in them. We will be healthier all the time and readier for the next pandemic. Then masks can be slapped on as a last layer of defense. Enough with the plexiglass, it’s just stupid and it’s time for it to go.
  • JULY: A new Lyme disease vaccine may be on the horizon (if you’re a human – if you are a dog, talk to your owner about getting the approved vaccine today.) I admit, I had to stretch a bit to find a positive story this month.
  • AUGUST: The Nordic welfare model works by providing excellent benefits to the middle class, which builds the public and political support to collect sufficient taxes to provide the benefits, and so on in a virtuous cycle. This is not a hopeful story for the U.S., where wealthy and powerful interests easily break the cycle with anti-tax propaganda, which ensure benefits are underfunded, inadequate, available only to the poor, and resented by middle class tax payers.
  • SEPTEMBER: Space-based solar power could finally be in our realistic near-term future. I would probably put this in the “interesting” rather than “hopeful” category most months, but I really struggled to come up with a hopeful story this month. I am at least a tiny bit hopeful this could be the “killer app” that gets humanity over the “dirty and scarce” energy hump once and for all, and lets us move on to the next layer of problems.
  • OCTOBER: The situation with fish and overfishing is actually much better than I thought.
  • NOVEMBER: Urban areas may have some ecological value after all.
  • DECEMBER: Covid-19 seems to be “disappearing” in Japan, or at least was before the Omicron wave. Maybe lessons could be learned. It seems possible that East Asian people have at least some genetic defenses over what other ethnic groups have, but I would put my money on tight border screening and an excellent public health care system. Okay, now I’m starting to feel a bit depressed again, sitting here in the U.S. where we can’t have these nice things thanks to our ignorant politicians.

Most interesting stories, that were not particularly frightening or hopeful, or perhaps were a mixture of both:

  • JANUARY: There have been fabulous advances in note taking techniques! Well, not really, but there are some time honored techniques out there that could be new and beneficial for many people to learn, and I think this is an underappreciated productivity and innovation skill that could benefit people in a lot of areas, not just students.
  • FEBRUARY: At least one serious scientist is arguing that Oumuamua was only the tip of an iceberg of extraterrestrial objects we should expect to see going forward.
  • MARCH: One study says 1-2 days per week is a sweet spot for working from home in terms of a positive economic contribution at the national scale. I think it is about right psychologically for many people too. However, this was a very theoretical simulation, and other studies attempting to measure this at the individual or firm scale have come up with a 20-50% loss in productivity. I think the jury is still out on this one, but I know from personal experience that people need to interact and communicate regularly for teams to be productive, and some people require more supervision than others, and I don’t think technology is a perfect substitute for doing these things in person so far.
  • APRIL: Hydrogen fuel cells may finally be arriving. Not so much in the U.S., where we can’t have nice things.
  • MAY: I learned about Lawrence Kohlberg, who had some ideas on the use of moral dilemmas in education.
  • JUNE: The big U.S. government UFO report was a dud. But what’s interesting about it is that we have all quietly seemed to have accepted that something is going on, even if we have no idea what it is, and this is new.
  • JULY: “Cliodynamics” is an attempt at a structured, evidence-based way to test hypotheses about history.
  • AUGUST: Ectogenesis is an idea for colonizing other planets that involves freezing embryos and putting them on a spaceship along with robots to thaw them out and raise them. Fungi could also be very useful in space, providing food, medicine, and building materials.
  • SEPTEMBER: Philip K. Dick was not only a prolific science fiction author, he also developed a comprehensive theory of religion which could possibly even be the right one. Also, possibly related but not really, if there are aliens out there they might live in creepy colonies or super-organisms like ants or termites.
  • OCTOBER: I thought about how to accelerate scientific progress: “[F]irst a round of automated numerical/computational experiments on a huge number of permutations, then a round of automated physical experiments on a subset of promising alternatives, then rounds of human-guided and/or human-performed experiments on additional subsets until you hone in on a new solution… [C]ommit resources and brains to making additional passes through the dustbin of rejected results periodically…” and finally “educating the next generation of brains now so they are online 20 years from now when you need them to take over.” Easy, right?
  • NOVEMBER: Peter Turchin continues his project to empirically test history. In this article, he says the evidence points to innovation in military technologies being driven by “world population size, connectivity between geographical areas of innovation and adoption, and critical enabling technological advances, such as iron metallurgy and horse riding“. What does not drive innovation? “state-level factors such as polity population, territorial size, or governance sophistication“. As far as the technologies coming down the pike in 2022, one “horizon scan” has identified “satellite megaconstellations, deep sea mining, floating photovoltaics, long-distance wireless energy, and ammonia as a fuel source”.
  • DECEMBER: Time reminded us of all the industries Elon Musk has disrupted so far: human-controlled, internal-combustion-fueled automobiles; spaceflight; infrastructure construction (I don’t know that he has really achieved any paradigm shifts here, but not for lack of trying), “artificial intelligence, neurotechnology, payment systems and cryptocurrency.” I’m not sure I follow a couple of these, but I think they missed satellites.

Continuing Signs of U.S. Relative Decline

Signs of U.S. decline relative to our peer group of advanced nations are all around us. I don’t know that we are in absolute decline, but I think we are now below average among the most advanced countries in the world. We are not investing in the infrastructure needed in a modern economy just to reduce friction and let the economy function. The annual length of electric blackouts in the U.S. (hours) compared to leading peers like Japan (minutes) is just one telling indicator. In March, I looked at the Build Back Better proposal and concluded that it was more like directing a firehose of money at a range of problems than an actual plan, but I hoped at least some of it would happen. My rather low but not zero expectations were met, as some limited funding was provided for “hard infrastructure” and energy/emissions projects, but little or nothing (so far, as I write this) to address our systemic failures in health care, child care, or education. The crazy violence on our streets, both gun-related and motor vehicle-related, is another indicator. Known solutions to all these problems exist and are being implemented to various extents by peer countries. Meanwhile our toxic politics and general ignorance continue to hold us back. Biden really gave it his best shot – but if this is our “once in a generation” attempt, we are headed down a road where we will no longer qualify as a member of the pack of elite countries, let alone its leader.

The Climate Change, Drought, Food, Natural Disaster, Migration and Geopolitical Instability Nexus

2021 was a pretty bad year for storms, fires, floods, and droughts. All these things affect our homes, our infrastructure, our food supply, and our water supply. Drought in particular can trigger mass migration. Mass migration can be a disaster for human rights and human dignity in and of itself, and managing it effectively is difficult even for well-intentioned governments. But an insidious related problem is that migration pressure can tend to fuel right wing populist and racist political movements. We see this happening all over the world, and the situation seems likely to get worse.

Tipping Points and other Really Bad Things We Aren’t Prepared For

We can be thankful that nothing really big and new and bad happened in 2021. My apologies to anyone reading this who lost someone or had a tough year. Of course, plenty of bad things happened to good people, and plenty of bad things happened on a regional or local scale. But while Covid-19 ground on and plenty of local and regional-scale natural disasters and conflicts occurred, there were no new planetary-scale disasters. This is good because humanity has had enough trouble dealing with Covid-19, and another major disaster hitting at the same time could be the one that brings our civilization to the breaking point.

So we have a trend of food insecurity and migration pressure creeping up on us over time, and we are not handling it well even given time to do so. Maybe we can hope that some adjustments will be made there to get the world on a sustainable track. Even if we do that, there are some really bad things that could happen suddenly. Catastrophic war is an obvious one. A truly catastrophic pandemic is another (as opposed to the moderately disastrous pandemic we have just gone through.) Creeping loss of human fertility is one that is not getting much attention, but this seems like an existential risk if it were to cross some threshold where suddenly the global population starts to drop quickly and we can’t do anything about it. Asteroids were one thing I really thought we didn’t have to worry much about on the time scale of any human alive today, but I may have been wrong about that. And finally, the most horrifying risk to me in the list above is the idea of an accelerating, runaway feedback loop of methane release from thawing permafrost or underwater methane hydrates.

We are almost certainly not managing these risks. These risks are probably not 100% avoidable, but since they are existential we should be actively working to minimize the chance of them happening, preparing to respond in real time, and preparing to recover afterward if they happen. Covid-19 was a dress rehearsal for dealing with a big global risk event, and humanity mostly failed to prepare or respond effectively. We are lucky it was one we should be able to recover from as long as we get some time before the next body blow. We not only need to prepare for much, much worse events that could happen, we need to match our preparations to the likelihood of more than one of them happening at the same time or in quick succession.

Technological Progress

Enough doom and gloom. We humans are here, alive, and many of us are physically comfortable and have much more leisure time than our ancestors. Our social, economic, and technological systems seem to be muddling through from day to day for the time being. We have intelligence, science, creativity, and problem solving abilities available to us if we choose to make use of them. Let’s see what’s going on with technology.

Biotechnology: The new mRNA technology accelerated by the pandemic opens up potential cures for a range of diseases. We need an effective biological surveillance system akin to nuclear weapons inspections (which we also need) to make sure it is not misused (oops, doom and gloom trying to creep in, but there are some ideas for this.) We have vaccines on the horizon for diseases that have been plaguing us for decades or longer, like malaria and Lyme disease. Malaria kills more children worldwide, year in and year out, than coronavirus has killed per year at its peak.

Promising energy technologies: Space based solar power may finally be getting closer to reality. Ditto for hydrogen fuel cells in vehicles, although not particularly in the U.S. (I’m not sure this is preferable to electric vehicles for everyday transportation, but it seems like a cleaner alternative to diesel and jet fuel when large amounts of power are needed in trucking, construction, and aviation, for example.)

Other technologies: We are actually using technology to catch fish in more sustainable ways, and to grow fish on farms in more sustainable ways. We are getting better at looking for extraterrestrial objects, and the more we look, the more of them we expect to see (this one is exciting and scary at the same time). We are putting satellites in orbit on an unprecedented scale. We have computers, robots, artificial intelligence of a sort, and approaches to use them to potentially accelerate scientific advancements going forward.

The State of Earth’s Ecosystems

The state and trends of the Earth’s ecosystems continue to be concerning. Climate change continues to churn through the public consciousness and our political systems, and painful as the process is I think our civilization is slowly coming to a consensus that something is happening and something needs to be done about it (decades after we should have been able to do this based on the evidence and knowledge available.) When it comes to our ecosystems, however, I think we are in the very early stages of this process. This is something I would like to focus on in this blog in the coming year. My work and family life are busy, and I have decided to take on an additional challenge of becoming a student again for the first time in the 21st century, but somehow I will persevere. If you are reading this shortly after I write it in January 2022, here’s to good luck and prosperity in the new year!

robot pollinators

Leave a reply

Somehow, startup companies have heard about my idea for robotic bees. (This is a Wall Street Journal article, which I don’t subscribe to, but I can get the idea from the first couple paragraphs. Sorry guys, I can’t afford to subscribe to anything, and if I have to pick one thing it will probably be to support my local paper. Except, if I lived in New York, it would not be the New York Times because weapons of mass destruction.) More likely, it’s a fairly obvious idea. And probably a good idea, if the pollinators really are disappearing worldwide. Then again, it’s a partial technological solution to replace a lost ecosystem service. Trucking around hives of domesticated honeybees to replace or supplement natural pollinators in farm fields is already a technological solution, if you think about it. Important questions: Do they sting? (I hope the answer is an obvious no.) Are we going to release clouds of robot pollinators into natural ecosystems? Probably not, this seems focused on agriculture. Are they going to be solar powered? It seems like it would be safer to have them return to a charging station, or else drop dead if their batteries run out.

This also brings up all the usual questions about valuing ecosystem services. Pollination is absolutely essential to life on earth, so pollinators are incredibly valuable in an economic sense. If we replace them with technology, does their value drop? In an economic sense, yes. In a moral sense, I would say no, at least to me.

sidewalk robots are legally pedestrians in some states

Leave a reply

Including, surprisingly, my state of Pennsylvania, which is rarely at the forefront of anything new. I am cautiously optimistic about this. It sounds like some pedestrian and bicycle advocates (I include myself in these groups) are against this. But I think slow-moving, light, predictable vehicles should not be a big problem. Fast, unpredictable vehicles driven by humans on infrastructure that does not consider the existence of pedestrians and bicyclists are what usually kills people. Also, every package on a slow, light, predictable robot is one that is not on a truck, and that should reduce the number of trucks over time. Trucks disproportionately kill people – pedestrians, bicyclists, and motorists alike. I realize that trucks also create some jobs, and job losses need to be dealt with through unemployment, education and training.

I see some problems looming, and these are infrastructure problems that need to be solved. Here in Philadelphia, sidewalks are often blocked by construction and parking because the law is either too lax or not enforced. Bike lanes often do not exist, and when they do they are often poorly designed, unprotected and unmaintained. Ramps for disabled people (which also help the rest of us, especially parents pushing strollers) often do not exist, are in a state of poor repair, collect water every time it rains, or are simply blocked by, again, construction or illegal parking. These are design and operational problems that have solutions, and the relevant public agencies (more than one, but one in particular) are either ignorant or incompetent or both. We need to fix the public agencies before we can design streets, bike lanes and sidewalks that are really going to work.

There’s another issue here. I don’t have the time, money, or expertise to sue individual contractors, landowners, or public agencies because they are blocking my walking path or bicycling lane. An Amazon or a UPS or a Google or an Uber will have these resources. This might be okay if it forces some change on big entities with deep pockets. This could be a problem for the individual homeowner or small business owner though. In my city, technically the sidewalk in front of my house is private property but public right-of-way. That means I can’t stop people from walking past, I can’t modify it significantly, but I can be sued or forced to repair it if it is not up to code. This might make sense on paper, but in practice cities are very lenient enforcing this on the small-time homeowner unless there is a serious incident. Sticking every homeowner in a city with a $10,000 repair bill (you might as well replace water and sewer lines while you are at it, which many people also don’t realize they own and are responsible for) would be a big burden on the middle class on down. Sidewalks are obviously public infrastructure and really part of the street, but this is one way cities push responsibilities and costs to the citizenry and try to keep taxes down a little bit. Taking over the sidewalks and raising enough tax revenue to keep them in a state of good repair would probably be the best answer from a technical and economic standpoint, but this would be a big legal and financial change for city government.

My utopian vision is for walking, bicycling, and slow, predictable, light, soft rounded vehicles to gradually displace most of the trucks, taxis and private cars that are out there. There would be less traffic at this point, almost no need for parking because the vehicles can just stack themselves somewhere out of the way when they are not in use. Maybe you only need one travel lane for big vehicles at this point (we’ll still want ambulances and fire trucks, although really I think these can be a bit smaller and quieter and still do the job), and robots, bicycles, and pedestrians can all have their own dedicated spaces and signals. You would have lots of room opened up for green infrastructure, sidewalk cafes, park benches, fountains, or whatever else you want to do. There is no technical or economic reason it couldn’t be done, and it would be cool. Cynicism, ignorance, and poor leadership are the reasons it won’t be done, at least not in most U.S. cities anytime soon.

military robot dogs

Leave a reply

The Air Force now has robot dogs patrolling at least one base in Florida. Fun pictures here.

The Mechanical Hound slept but did not sleep, lived but did not live in its gently humming, gently vibrating, softly illuminated kennel back in a dark corner of the firehouse. The dim light of one in the morning, the moonlight from the open sky framed through the great window, touched here and there on the brass and the copper and the steel of the faintly trembling beast. Light flickered on bits of ruby glass and on sensitive capillary hairs in the nylon-brushed nostrils of the creature that quivered gently, gently, gently, its eight legs spidered under it on rubberpadded paws…

At night when things got dull, which was every night, the men slid down the brass poles, and set the ticking combinations of the olfactory system of the Hound and let loose rats in the firehouse area-way, and sometimes chickens, and sometimes cats that would have to be drowned anyway, and there would be betting to see which the Hound would seize first. The animals were turned loose. Three seconds later the game was done, the rat, cat, or chicken caught half across the areaway, gripped in gentling paws while a four-inch hollow steel needle plunged down from the proboscis of the Hound to inject massive jolts of morphine or procaine. The pawn was then tossed in the incinerator. A new game began…

It was half across the lawn, coming from the shadows, moving with such drifting ease that it was like a single solid cloud of black-grey smoke blown at him in silence. It made a single last leap into the air, coming down at Montag from a good three feet over his head, its spidered legs reaching, the procaine needle snapping out its single angry tooth. Montag caught it with a bloom of fire, a single wondrous blossom that curled in petals of yellow and blue and orange about the metal dog, clad it in a new covering as it slammed into Montag and threw him ten feet back against the bole of a tree, taking the flame-gun with him. He felt it scrabble and seize his leg and stab the needle in for a moment before the fire snapped the Hound up in the air, burst its metal bones at the joints, and blew out its interior in the single flushing of red colour like a skyrocket fastened to the street. Montag lay watching the dead-alive thing fiddle the air and die. Even now it seemed to want to get back at him and finish the injection which was now working through the flesh of his leg.
