What if the greatest magic in the D&D world was actually technology? In this season 10 finale of FGGGbT we celebrate the gnomes: D&D’s most exuberant, most creative, and most explosion-prone technological pioneers. They dig into gnomish clockwork constructs, airships, and the philosophical question at the heart of every gnomish invention: is it poorly executed, or is it just missing safety features? Daniel J. Glenn argues mediocre execution. Dr. Michael Dennin and Ben Siepser argue it’s the purest form of “fail fast” engineering — and the debate gets surprisingly heated. Along the way they explore gnomish technology that mirrors real-world inventions — the Cup of Infinite Water (a pocket fire hose), the Magical Alarm Clock (which may wake you with a fireball), Hare’s Legs spring boots (ankle support sold separately), the Excessively Thin Hat of Excessive Coolness (remove before leaving extreme heat), and the marble-dispensing escape buckle that definitely won’t trip you up. They also talk dark vision goggles, the physics of cat eye reflectivity, the engineering of miniaturization, and why gnomes are the ultimate anti-capitalists — inventing purely for the joy of invention.

What do a brain-eating squid creature, a giant praying mantis, and a snake person have in common? They’re all psionic — and that’s about where the similarities end. In this episode of FGGGbT, we tackle the most challenging taxonomy of the season: psionic creatures. Unlike the undead or the Fey, this group has almost nothing in common except one thing — the power of the mind. They kick things off with the most iconic psionic creature in D&D: the mind flayer — part Cthulhu, part Billy Corgan, all terrifying — breaking down their reproductive cycle (ceremorphosis), their elder brain hive mind, and whether their brain-eating habit is a dietary preference or a biological necessity. From there they explore the Githyanki and Githzerai — two genetically identical races who responded to mind flayer subjugation in completely opposite ways, one militaristic and dragon-riding, one monk-like and meditative — before moving to the Thri-kreen, the praying mantis creatures whose entirely open telepathic society raises a disturbing question: what would a world with no mental privacy actually look like? They also dig into the Yuan-Ti and their cold, emotionless psionic manipulation, the convergent evolution of psychic powers across wildly different species, and the Elan — a human who voluntarily transforms into an entirely new psionic creature — asking whether gaining mental powers is enough to make you a different species entirely.

What separates a pixie from a sprite, a brownie from a hag, and a nymph from a siren — and why does any of it matter? In this episode of FGGGbT, we tackle one of the most ambitious taxonomy projects of the season: building a complete classification system for the Fey. Unlike the undead, who are defined by their deadness, the Fey are defined by their otherness — their deep, fundamental connection to nature and the feywild. Using six core classification categories — former mortality, degree of humanity, power hierarchy, corporeal vs. non-corporeal, elemental connections, and relationship to mortals — Daniel J. Glenn, Dr. Michael Dennin, and Ben Siepser work through the full roster: pixies, sprites, brownies, leprechauns, satyrs, centaurs, dryads, nymphs, treants, and hags. Along the way they debate whether satyrs are evil or just really fun at parties, why the centaur is nature’s original cyborg, whether hags are actually villains or just very aggressive conservationists, and how every Fey creature ultimately represents some aspect of nature brought to life. They also introduce a simple four-bucket framework for understanding the Fey: helpers, tricksters, enchanters, and corruptors — and how every bargain with the Fey falls into one of those categories.

What separates a skeleton from a lich — and does immortality inevitably make you evil? In this episode of FGGGbT, the Brain Trust — Daniel J. Glenn, Dr. Michael Dennin, and Ben Siepser — tackle one of the most ambitious projects of the season: building a complete taxonomic classification system for the undead. Using six core categories — physical presence, soul spectrum, voluntary vs. involuntary transformation, dead-then-reanimated vs. transformed-while-living, life force alteration, and sensitivity to pure things — they systematically break down skeletons, zombies, mummies, ghosts, banshees, liches, and vampires with the rigor of scientists and the enthusiasm of lifelong D&D players. Along the way they debate whether mummies are just high-quality zombies, whether a ghost can choose to stay or is forced to linger, and whether the vampire or the lich is the true apex undead predator. They also tackle the big philosophical question at the heart of all undead lore: does immortality inevitably lead to evil? Ben Siepser’s argument — that anything divided by infinity equals zero, making all moments meaningless — might just be the most elegant explanation for why every lich eventually goes mad and every vampire eventually stops caring about the living. Whether you’re a dungeon master building your undead roster or just someone who’s always wondered what actually separates a mummy from a zombie, this episode has the answers.

What if crystals could store your personality — and eventually become sentient? In this episode of FGGGbT, the Brain Trust — Daniel J. Glenn, Dr. Michael Dennin, and Ben Sieper — dive into the fascinating world of psionic magical items, exploring the real science of crystals, information theory, and the question that haunts AI researchers and D&D players alike: when does something stop being a tool and start being alive? We break down two categories of psionic items — crystals and tattoos — through the lens of materials science, electronics, and quantum physics. We explore how dorjes work like crystal capacitors with discrete energy symmetries, why they can only store odd numbers and never more than 17 charges, and how the Psicrystal — grown from a shard of a psionic’s own personality — maps perfectly onto modern AI development and information theory. Dr. Dennin introduces Claude Shannon’s information theory (yes, the guy who coined the word “bit”) and explains why psionics aren’t just manipulating energy — they’re manipulating the fundamental probability structure of reality itself. We also dig into psionic tattoos, why their information density is limited by the resolution of ink on skin, and why you should probably vet your tattoo artist very carefully before letting them encode your psychic powers. Finally, we tackle the big question: at what point does a growing Psicrystal cross the line from clever storage device to sentient being — and is wisdom just being too old and tired to care?

What happens when you put a Sphere of Annihilation inside a Bag of Holding? In this episode of FGGGbT, the Brain Trust — Daniel J. Glenn, Dr. Michael Dennin, and Ben Sieper — go deep on magical item combos, the science of extradimensional space, the world's most powerful glue, potion mixology, and the surprisingly complex question of when a sword becomes a person. We kick things off with the Bag of Holding — how its constant weight hints at real theories of gravity and extra dimensions — before combining it with the Sphere of Annihilation (a dense ball of antimatter in a magical containment field) and exploring the three probabilistic outcomes, including a spontaneous rip in space-time that sends your party to a random time period. Then we tackle Sovereign Glue, why no substance in our world truly sticks to everything, and the hilariously impractical physics of storing oil of slipperiness in a bottle. We also dive into potion mixology — why mixing potions in your body is random (your gut biome matters), what quantum wave interference has to do with making a potion permanent, and why you should always read the label before chugging two potions at once. Finally, we explore sentient magical items: Black Razor, Night Blood, and the Professor Orb — and debate whether these items contain trapped souls, emergent AI, or something else entirely.

What makes a magical item truly magical — and how many is too many? In this episode of FGGGbT, the Brain Trust — Daniel J. Glenn, Dr. Michael Dennin, and Ben Sieper — dive deep into the science, physics, and storytelling behind D&D magical items, and things get wonderfully chaotic. We explore how magical items are created through the fantasy equivalent of metal alloying and materials science — from Damascus steel to samurai folding techniques — and how the concept of magical attunement maps perfectly onto impedance matching in electronics. We break down the difference between a non-magical plus one sword (medieval ergonomics) and a truly magical weapon, why magical weapons can harm magical creatures when ordinary ones can’t, and how luck itself might be a form of short-range time travel or quantum probability manipulation. Then we get into the really fun stuff: the Cloak of Billowing, the Luck Blade, the Cursed Shield of Missile Attraction, the Bag of Beans, the Folding Boat (which turns out to be an excellent murder weapon), and the ultimate chaotic device — the Deck of Many Things. Plus, does drawing a card that gives you a castle reveal fate or create it? And did your rich uncle have to die for that to happen? Whether you’re a dungeon master looking for inspiration or a player obsessed with magical loot, this episode is for you. Topics Covered: How magical items are created: alloying, Damascus steel & samurai folding Magical attunement vs. non-magical attunement (medieval ergonomics) Why magical weapons harm magical creatures Impedance matching & the three-item attunement limit Luck as quantum mechanics, divination & short-range time travel The Luck Blade, Cursed Luck Stone & Shield of Missile Attraction The Bag of Beans, Deck of Many Things & wild magic items Favorite magical items: Cloak of Billowing, Folding Boat & Nolzur’s Marvelous Pigments Cursed items — liabilities or creative opportunities?

What if the eight schools of D&D magic were actually eight fundamental forces of the universe? In this episode of FGGGbT, the Brain Trust — Daniel J. Glenn, Dr. Michael Dennin, and Ben Sieper — break down all eight schools of magic through the lens of real science, from particle physics and chemistry to neuroscience and quantum mechanics. We explore how the eightfold way in particle physics maps perfectly onto the eight schools of magic, and introduce the theoretical “magon” — the fundamental particle of spellcasting. Then we go school by school: Abjuration as proton-like defensive particles, Conjuration as spacetime manipulation, Divination as probabilistic quantum prediction, Enchantment as brain chemistry and pheromones, Evocation as pure chemistry-based destruction, Illusion as electromagnetic sense manipulation, Transmutation as nuclear physics, and Necromancy as life-force control. We also debate which school is the most dangerous, the most easily abused, and the most morally complex — and why charm, illusion, and necromancy form a uniquely troubling trio. Whether you’re a D&D wizard trying to pick your school, a science nerd who loves fantasy, or just someone who wants to know how a fireball is different from a cone of cold, this is the episode for you. Topics Covered: The eightfold way in particle physics & the “magon” Abjuration, Conjuration, Divination, Enchantment, Evocation, Illusion, Transmutation & Necromancy The science behind each school: chemistry, nuclear physics, neuroscience & quantum mechanics Which school requires the most energy? The ethics of necromancy, enchantment & illusion Real-world parallels: mirages, pheromones, nuclear reactions & optical illusions Listen to all our episodes on magic: The Magical World of….well MAGIC!

How do spells actually work — and why do some only affect certain creatures? In this episode of FGGGbT, the Brain Trust — Daniel J. Glenn, Dr. Michael Dennin, and Ben Sieper — break down the mechanics, physics, and philosophy behind spellcasting in D&D and beyond. We explore the power of true names and pronunciation (Cthulhu, anyone?), the science behind spell foci like wands — including a deep dive into electrostatics and why wood might not be a coincidence. We dig into why Charm Person doesn’t work on a dog, why Hold Monster is harder than Hold Person, and why elves are immune to Sleep (spoiler: they don’t actually sleep). Then we get into the physics of Fireball vs. Wall of Fire, including a true story about an accidental wall of fire in a college lecture hall. Finally, we tackle one of science’s oldest debates — is magic (and math) invented or discovered? — using the Newton vs. Leibniz and Edison vs. Tesla rivalries as our guide. Whether you’re a D&D player who’s always wondered why Otto’s Irresistible Dance might not work on someone without legs, or a science fan curious about the line between magic and physics, this episode is for you. Topics Covered: True names & the power of words in magic systems Spell foci: wands, electrostatics & druidic focus items Charm Person vs. Charm Monster — the biology of persuasion Hold Person vs. Hold Monster & paralysis mechanics Why Sleep affects (almost) everyone — and why elves are immune The physics of Fireball, Wall of Fire & controlling chaotic energy Named spells & the “second discoverer” effect (Newton, Leibniz, Tesla, Edison) Is magic invented or discovered?

Could humans actually develop psychic powers? The science says… maybe. In this episode of FT GBT, the Brain Trust — Daniel J. Glenn, Dr. Michael Dennin, and Ben Sieper — dive into the often-overlooked world of psionics, exploring the real neuroscience and physics behind mind powers in D&D, Stranger Things, X-Men, Star Wars, and Warhammer 40K. We break down why psychic energy works as a continuum (unlike the discrete “chunks” of arcane spell slots), and how that maps onto pop culture icons like Eleven from Stranger Things. We explore the three categories of psionic powers — attacking the mind, defending the mind, and telekinesis — and dig into the real-world science behind each: from electromagnetic brain signals and sports psychology breakdowns (Simone Biles, Ric Flair) to Faraday cages, Jedi mind tricks, and why a tinfoil hat might not be such a bad idea after all. We also tackle the big question: can a non-psychic person defend against a psychic attack, or are they just a fish in a barrel? Whether you’re a D&D player curious about psionics, a sci-fi fan, or just someone who’s ever wondered if you could move a remote control with your mind, this episode is for you. Topics Covered: What are psionics & why they’re D&D’s most underrated subsystem Psychic energy as a continuum vs. discrete spell slots Mind attacks: ego whips, mind thrust & psychic horror Real-world parallels: sports psychology, CIA training, hypnotism Defending the brain: Faraday cages, Magneto’s helmet & Warhammer 40K The physics of telekinesis Eleven (Stranger Things), X-Men, Star Wars & psionic pop culture Can non-psychics resist psychic attacks?

Show Notes Can science explain how divine magic actually works? In this episode the FGGGbT Brain Trust tackles the rules, biology, and ethics behind divine magic in Dungeons & Dragons. From the life-force mechanics powering clerics and druids to the darkest corners of necromancy — we break it all down. We explore how death functions […]

Show Notes Can neuroscience and physics explain how D&D spell slots actually work? In this episode of FGGGbT (Fascinating Gadgets, Gizmos & Gear-Based Technologies), the Brain Trust — Daniel J. Glenn, Dr. Michael Dennin, and Ben Sieper — crack open the skulls of arcane magic users to figure out what’s really going on inside. We […]

Show Notes What is magic, really? In this episode, The Brain Trust dig into one of fantasy’s most fundamental questions — not just what magic does, but what it is. They explore why every great fantasy setting gives magic its own internal rules (and why breaking those rules breaks the world), how magic functions less […]

Vampires are the one monster that seems to have been around forever (I mean they are immortal), and they never seem to go away.  Their popularity may wax and wane, but these predators are always present, ready to suck away our life force in order to preserve theirs.  Even when it seems like we have […]

Everyone remembers the famous line in “Raiders of the Lost Ark” where Indy says “Why did it have to be snakes?”  Well our Daring Druid (and resident ophiophilist) Ben Siepser often wonders “Why isn’t it ALWAYS snakes”?  So this week we take a look at a few of our favorite snake-based humanoids including the naga, […]

Are you ready for MORE petrification!  This week we discuss the basilisk, a creature that can turn you to stone just by looking at you.  Well it has to meet your gaze, but we get into the specifics so you won’t get fooled.  It is also gigantic, which is something to consider.  Listen as we […]

There are certain creatures in myth and legend who have been said to have the ability to turn those they encounter into stone.  This week we profile one of those creatures, the cockatrice.  With the head of a rooster, the body of a lizard, and the wings of a bat, this tiny creature can petrify […]

There is a reason every little girl wants a pony:  Because horses are really cool.  They are so great that the world of D&D is filled with horse-based creatures including the unicorn, pegasus, nightmare, and even the centaur.  Why this form?  What tactile advantages does it provide?  How can a horse fly but a pig […]

As human beings, we are lucky enough to be at the top of the food chain.  Being at the top means there is nothing above us.  No predators to watch out for, nothing evolving to eat is specifically.  We never have to check our rear view.  Or do we?  In this episode we discuss what […]

The forest is filled with all kinds of creatures great and small. It is also home to one of the most mischievous and dangerous creatures: The Dryad. The woodland spirits are tied to a singular oak tree. They are so tied in fact, that they cannot stray more than 1000 feet from their home. This […]

Everyone knows that trees are alive…but today we are only concerned with the ones that run around.  We are talking treants from D&D, Ents from Lord of the Rings, and the Fighting Trees of Oz.  Are these creatures plants with animal traits, or secret animals that look like plants?  We discuss the possibilities.  The answer […]

When it comes to D&D, there is one apex predator:  The Dragon.  It is even in the name!  These winged creatures come in all sizes and colors, which is lucky for adventurers.  See, a dragon’s color tells you a lot about the creature, including their alignment, their powers, and their magic resistance.  When you are […]

Once you sign up to be an adventurer, it is a given that you will raid every chest you come across.  Some will have locks, some will have traps, and some may even eat you.  That last option is the topic of today’s show as we discuss mimics in D&D.  These creatures can take the […]

If you wear a belt buckle (as any good adventurer does), then battling a rust monster is the only situation where you can get caught with your pants down.  These creatures seem to feed on metals, which means that unless you are proficient with clubs and quarterstaves, you are in big trouble.   If you have […]

Our 10th season begins!  We decided to do something a little different this year.  We were inspired by last season’s episode on “Delicious in Dungeon”, so we are taking a look at Dungeons & Dragons monsters and explaining how they work.  It turns out, there is a lot of literature on these creatures, and none […]

Once you reach 200 episodes, you start to consider life expectancy. Should a podcast go on forever? Should a human live forever? While I have no idea about the first one, today’s episode is about the second one. Sure we will quickly congratulate ourselves but then we get down to the real work: Researching the […]

For many generations, Santa has been seen as a portly fellow who’s hard work throughout the year makes Christmas Day magical for all.  That view is becoming a thing of the past.  We have done a lot of episodes on the technology of Christmas, and this year we have a new entry:  Red One.  This […]

Raiding tombs is tough work, which is maybe Lara Croft, the world’s most famous tomb raider, is such a jerk.  Personally I like Indiana Jones a lot better, but he was definitely not as athletic as Lara.  Sure he had the bullwhip, but Lara uses a magnetic grappling hook with the proficiency of a samurai […]

On this show we discuss how the world will end every other episode, and since we discussed robot survival skills on the last episode, once again, we are due.  This week we actually explore what Dennin calls the ultimate apocalypse:  Dying if you fall asleep.  This is the concept of Markipliers new series “The Edge […]

The early part of this century saw an explosion of television shows demonstrating extreme survival skills.  I am talking about Survivor, Naked and Afraid, Man VS Wild, or anything Bear Grylls stars in.  I think this was really to show how far we humans have gone from nature.  We have lost almost all of our […]

Let’s say you work with classified documents, or you just have a boring job you want to forget.  Wouldn’t it be great if you could just turn off your brain as you entered work and turned it back on when you left the building?  You know, give the heavy lifting to your unconscious or whatever.  […]

Beetlejuice has been called “The Ghost with the Most”, but the most of what?  Is there something special that he has that other ghosts in the afterlife don’t have?  The short answer is YES, and it involves the Deadon particle.  Don’t worry, we explain everything for you in this episode.   These give him the power […]

My guess is that most people listening to this episode will NOT find themselves lost in a fantasy dungeon (unless it is while playing a game of D&D of course).  However should you, it may become necessary to start catching and eating monsters.   Luckily the Brain Trust has just finished watching the anime “Delicious in […]

Humans are visual creatures, but we still rely heavily on our auditory senses to navigate the world.  We are also loud by nature, which is why New York City is constantly at 90 decibels.  My point is this:  If our survival is dependent on staying silent, I think we are doomed.  Most of us at […]

Today we decide to take a trip BACK to the planet of Dune, which is a place like none other.  In our first episode we talked about the lack of water and how important saving every drop is.  Well this time we take a deep dive into that waterless pool to give you as many […]

Tornadoes are one of the most truly devastating forces in nature.  They can appear out of nowhere, destroy entire towns, and then disappear without a trace.  They are categorized not by their power, but by the amount of damage they cause.  So how do these killer vortexes form?  And why are they almost exclusively a […]

At the end of the last episode things looked pretty bleak. Highly advanced aliens are on their way and they are stifling our scientific breakthroughs. But humans are resilient. The aliens call us bugs, but nothing is more hardy than the cockroach. But what can we do? Well we specialize in out of the box […]

The TV show “3 Body Problem” introduces a major conundrum for humanity:  Aliens are on their way, and there is nothing we can do about it.  Are they friendly?  Are they hostile?  Who knows (Who am I kidding, we all know they will eventually turn on us)?  There is an upside though:  It will take […]

“When Hell Freezes Over” is a common saying, but what does it even mean? Sure religious doctrine would have you believe that Hell is a place of fire and brimstone, full of lakes of lava, overcooked burritos, nuclear meltdowns, and other really hot stuff. But we also talk about the chill of the grave, and […]

We have been taught that Superman is the icon for truth, justice, and the American way.  He is the ultimate superhero, and always does what it right.  He is also an alien with more strength and power than anything we can imagine.  There are no counters to him.  Well except Kryptonite which is unbelievably rare.  […]

We’ve discussed how to build your own underground bunker, but what if you let a company like Vault-Tek do that for you?  In the world of Fallout, Vault-Tek is not the most trustworthy company.  They blew up the entire world to eliminate their competition!  While I do respect their hustle, it does leave the world […]

There are very few characters that truly stand the test of time.  Superman and Batman are almost 90, but there are peaks and valleys to their popularity.  The Teenage Mutant Ninja Turtles have been consistently in the spotlight since the mid-80’s, which is a feat in my opinion.  As everyone knows, despite being 40 years […]

History is littered with tragic events, things that change the course of your life.  Some events have the magnitude to change the social order of the world itself.  What if you could go back and right these wrongs?  Who among us wouldn’t go back and stop 9/11, or prevent the holocaust?  Well this week, we […]

Have you ever wondered what would have happened if during major moments of your life you simply made a different decision?  You know, went left instead of right?  What would your life be like now?  Well thanks to our old friend Quantum Physics, that decision happened, and that alternate reality exists. And if that life […]

Fighting crime is a dangerous business.  In the best of circumstances, you have keep your senses sharp, and maintain your focus at all times.  Seeing your enemy and hearing their movements are vital to your success, but what if you can’t see or hear?  What do you do then?  Well for Daredevil who is blind, […]

He-Man is a Master of the Universe, and he is granted that status by The Power of Greyskull.  But what is this power?  We are a science show, so we believe there is no such thing as magic…or is there?  Is magic it’s own force that bind the physics of Eternia?  How can it turn […]

The shark is the ultimate killing machine.  It does three things:  swim, eat, reproduce.  It has a conveyor belt of teeth which basically makes it a large, living, underwater chainsaw.  The only thing that would make it deadlier is to make it bigger.  Enter the Megalodon, which was just like out great white sharks, except […]

For any kid, the prospect of touring a magical chocolate factory is a dream come true, especially one whose secrets have been hidden for decades.  If you are one of the lucky few with a Golden Ticket, your life will never be the same.  See, Willy Wonka is not a run of the mill chocolatier:  […]

Who among us hasn’t wanted to find a magical lamp complete with a resident Genie to give us three wishes?  Heck, I would even take a monkey paw, knowing full well that I have to phrase things exactly right to avoid unintended dire consequences.  Well this week, the Brain Trust assembles to discuss wishes, how […]
