Episodes

Ep. 219 Mastering Magic Items 08.07.2026

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 —...

Ep. 218 Schools of Magic 01.07.2026

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 ma...

Ep. 217 How Spells Work 24.06.2026

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 dee...

Ep. 216 Psionics: Mental Magic 16.06.2026

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...

Ep. 215 Divine Magic 10.06.2026

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 as a control valve for life energy , why souls are the curren...

Ep. 214 Arcane Magic Users 03.06.2026

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 break down Vancian magic and why wizards forget spells a...

Ep. 213 What is Magic? 27.05.2026

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 like a supernatural miracle and more like a natural force nobody fully unde...

Ep. 212 Vampires 12.11.2025

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 discussed everything there is to say about these creatures of the night, the Brain Trust comes throu...

Ep. 211 Snake Folk 05.11.2025

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, the ophidians, and the dreaded Yuan-Ti.  Just a bit of a warning, the reproductive cy...

Ep. 210 Basilisk 30.10.2025

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 talk about how near-sightedness as an advantage, the deliciousness of magic shell, and how spitting on goggle...

Ep. 209 Cockatrice 23.10.2025

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 the largest of creatures with a single touch.  They are feared in the fantasy world, since their small si...

Ep. 208 Horse-based Creatures 16.10.2025

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 can’t?  We will answer all these questions on this week’s episode. Facebook Twitt...

Ep. 207 Man-Eating Plants 08.10.2025

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 makes a good human predator, and it turns out its plants!  That’s right, if we are going to be taken out, it will be by...

Ep. 206 Dryads 02.10.2025

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 can be a problem, so they have devised ways of tricking and charming beautiful men to come and stay with t...

Ep. 205 Treants 25.09.2025

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 may be found in upside-down jelly fish & leafy sea slugs.  Plus we s...

Ep. 204 Dragons 18.09.2025

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 going after something so powerful, you will take any advantage you can.  W...

Ep. 203 The Mimic Cycle 10.09.2025

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 form of anything wooden, metal, or stone, which is usually a treasure chest.  Not only that, but we will unveil...

Ep. 202 Rust Monsters 04.09.2025

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 good loot, avoid these creatures at all costs.  Luckily in this episode we will tell you how...

Ep. 201 The Gelatinous Cube 28.08.2025

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 has been written about more than the classic Gelatinous Cube, offici...

Ep. 200 The Quest for Immortality 12.12.2024

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 quest for immortality. It turns out we are coming alarmingly close to halting the a...

Ep. 199 A Santa Who’s Jolly, Jacked, & Rides a Sleigh That’s Packed 04.12.2024

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 Santa is absolutely jacked, and has tremendously high powered technology at his control, including a...

Ep. 198 Raiding Tombs in 10 Easy Steps 27.11.2024

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 warrior.  She is excellent at parkour, and is more agile when it comes to avoiding traps. ...

Ep. 197 The Dangers of Sleep 20.11.2024

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 of Sleep”, which is what inspired this episode.  How long do you think y...

Ep. 196 Robot Survival Skills 13.11.2024

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 primal instincts, but in fairness, we do have them.  Our inner caveman is always simmering b...

Ep. 195 Creating An Entirely New You 06.11.2024

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.  If this sounds like a dream come true, then you will LOVE the TV show Severance.  Here people...
