Logo for the podcast “Researching in Times of Covid-19”

The world is currently griped by the Covid-19 pandemic, which has affected almost all facets of society. Streets are empty, shops are closed, bars are shut, and many people are unable to visit their loved ones. The world at the start of 2020 was a very different place.

Many countries have put strict lockdown conditions in place. For instance, in Ireland, people are not allowed to venture more than 2 km from their home, unless in the case of an emergency, for food shopping or medicines, or if they are deemed to be essential frontline workers. In the Netherlands, there is no such 2 km limit but the majority of businesses are closed and many people are working for home. This affects a multitude of people – ranging from bankers to software developers, and from radio reporters to scientific researchers.

I’m currently based at Eindhoven University of Technology (TU/e) where the current lockdown situation has affected the research and teaching of hundreds of TU/e staff. To gauge how researchers are dealing with the changes in their work environment and how the lockdown has affected their work, I’ve just launched a new podcast series. It is called “Researching in Times of Covid-19” and in each episode I speak to a different researcher from a different department at TU/e.

You can listen to the podcast episodes on this website or you can listen on Spotify, Castos, iTunes, Google Podcasts, or Pocket Casts.

You can read more about the podcasts in this news article on the website for Eindhoven University of Technology.

Stay safe and stay healthy!

“How to Build an Iron Man Suit” Visits Comicasa

Speaking at Comicasa, Feb 21st 2020
Speaking at Comicasa, Enschede, the Netherlands, February 21st 2020

It’s always good to visit home, to where it all started. In terms of my adventures in the Netherlands, home, and where it all started back in 2012, is Enschede. While I lived there the seeds for my superhero escapades were sown, and I couldn’t have imagined speaking about my new book “How to Build an Iron Man Suit” for the first time in the Netherlands anywhere else. On Friday February 21st I did just that when I spoke at the fantastic Comicasa comic book store – a must visit for fans of superheroes and more.

Those in attendance were first treated to a “Iron Man 101” course delivered splendidly by Robert van der Weide-Zeelenberg. Robert outlined the history of the character Iron Man including his inauspicious start at Marvel Comics as well as the evolution of the character and some of the suits that have featured in comic book issues over the years.

Then it was my turn to speak about the science and technology behind the development of an Iron Man suit. The audience experienced the wonder of an exoskeleton suit, EEG brainwave-reading technologies, advanced wound healing treatments, and lots more. Specific scenes from the films were very much in the spotlight, which seemed to please the comic book and film-loving audience no end. The end of the talk was marked by an open discussion on the technological tribulations behind developing a real Iron Man-like suit, and whether such a technology would be of benefit to society.

Many thanks to Robert, Peter, and everyone at Comicasa for hosting the talk. My new book “How to Build an Iron Man Suit“, as well as my other books, are available to purchase at Comicasa. And be sure to visit the store to experience the comic book ambience. It’s such a cool place to sit down and read a comic book or ten.

Stay tuned for more Iron Man banter.

Secret Science of Santa Claus: How do reindeers fly Santa’s sleigh around the world?

This is an article that I wrote for RTE’s Brainstorm website. The original article can be found here.

For more information on the Secret Science of Santa Claus check out information on my book “Secret Science of Santa Claus“.

In a matter of days, Santa Claus will set out on an incredible round-the-world trip to deliver presents to millions of children. Every year, his schedule gets busier, due in part to the ever-increasing world population. To help him achieve this Christmas delivery goal, Santa uses a truly unique form of transport: a flying sleigh that is guided by a troop of flying reindeers. But how does the sleigh fly? And does it fly in a sustainable way?

Before looking at the science behind Santa’s flying sleigh and flying reindeer, why did Santa Claus pick reindeer to pull the sleigh in the first place? As you already know, Santa Claus’ base of operations is located in the Arctic Circle, which contains parts of Canada, the US, Greenland, Sweden, Norway, Finland, and Russia. The Arctic Circle is home to many animals such as the Arctic fox, the Arctic hare, polar bears, snowy owls, and of course reindeer.

According to the 2018 Arctic Report Card from NOAA’s Arctic Program, there are roughly two million reindeer in 23 major herds in Arctic regions. For centuries, people living in Arctic regions such as the Sami and Nenets have used reindeer to transport people and goods across vast distances. So you could say that Santa Claus is just copying an old tradition.

Nonetheless, it is puzzling that the sleigh and reindeer don’t have wings like modern aircraft. Well, aeroplanes didn’t exist when Santa Claus and his elf-scientists were creating their reindeer-based flying system in the early 18th century. The first successful flight of any aircraft with an engine took place near Kitty Hawk, North Carolina on December 3rd 1903. The pilot that day was Orville Wright, who along with his brother Wilbur built an aircraft known as the Wright Flyer I. This means that Santa’s designs couldn’t have been influenced by the work of the Wright Brothers or any other aviation pioneers. And the sleigh doesn’t have jet engines because jet engines were only developed in the middle of the 20th century.

Of course, Santa Claus and the elf-scientists could have invented mechanical wings that could be worn by the reindeer during flight. But these would more than likely have been very awkward to wear for the reindeer. Plus the reindeer are harnessed quite close to each other and they wouldn’t have been able to fully extend their wings. Instead of wings and jet engines, Santa and the elf-scientists turned to something more astounding and sustainable. They turned to magnetic levitation.

What the heck is magnetic levitation?

A magnet – just like that used to keep your summer holiday souvenirs on your fridge – has two magnetic poles, a north pole and a south pole. If you’ve ever played with magnets you’ll know that unlike poles attract like poles repel.

Magnets are being used in modern transport systems such as magnetic levitation or maglev trains. Just like a traditional train, a maglev train travels along a track but, unlike a traditional train, a maglev train does not touch the track. The train essentially floats above the track because magnets on the bottom of the train push off the magnets on the track. Importantly, the magnetic lifting force counteracts the weight of the train due to the force of gravity; otherwise the train could never levitate. Typically maglev trains float about 10cm above the track.

One maglev approach is known as electrodynamic suspension (EDS) and involves the use of superconducting electromagnets. Superconductors are super by name and by nature. When these materials are cooled to very low temperatures, they have zero electrical resistance and generate a magnetic field. In an EDS maglev train, superconducting magnets are located inside the train. As the train passes over the track, the magnetic fields in the track and train repel each other leading to a levitating or floating train.

Because of the lack of friction with the track and the aerodynamic shape of maglev trains they can reach incredibly fast speeds. The fastest speed for a maglev train is 603 km per hour, which was achieved in April 2015 in Japan by JR Central’s L0 train!

Santa’s magnetic levitating reindeer

One of the big problems with superconducting materials is that they need to be cooled to very low temperatures before they can start to act like a magnet. This requires the use of expensive cryogenic cooling systems where liquid helium or liquid nitrogen is used to cool the materials to freezing temperatures.

But Santa Claus doesn’t need to worry about carrying cryogenic cooling systems on his sleigh. That’s because Santa Claus and the elf-scientists have developed the “holy grail” of superconducting materials: a room-temperature superconducting material. This is a material that behaves as a superconductor at much warmer temperatures, i.e. around 20 °C.

Santa and the elves installed this material on the runners of the sleigh and in the shoes worn by the reindeer. When Santa Claus passes electricity through the superconductors they generate a magnetic field. To levitate, this magnetic field needs to push off a second magnetic field, which is the Earth’s magnetic field. Although the Earth’s magnetic field is quite weak (the magnetic field from a fridge magnet is 100 times stronger), Santa’s technology compensates for this. When the sleigh’s magnetic field is high, Santa and the sleigh can fly higher and faster. And when the strength of the sleigh’s magnetic field is decreased, the sleigh flies lower and slows down. 

Just like a car needs a battery to help kick start the engine, Santa’s sleigh also carries a battery to switch on the sleigh’s magnetic field. Rather than using a lithium-based battery (which won the Nobel Prize in Chemistry 2019), Santa and his elves have opted for an advanced recyclable sodium-based battery. Added to that, the levitating sleigh emits no greenhouse gases or toxic substances into the atmosphere, which can only be a good thing for the environment. So in effect the sleigh is carbon neutral. 

The only minor issue with the whole flying process is that Santa’s reindeer emit methane in the form of reindeer flatulence (basically reindeer farts) during their round-the-world trip. But don’t worry: Santa Claus and the elf-scientists have that covered too!

The Arrival of “How to Build an Iron Man Suit”

In February 2019, I set out on a writing adventure. I had a plan and I hoped that I would be able to stick to it. In my apartment I scribbled some notes, random musings, and a rough timetable on my whiteboard. It was a serious undertaking – to write a book in approximately 6 months from scratch. But I was motivated, intrigued, and suitably placed to write it. The aim was to write a book “How to Build an Iron Man Suit” with the content inspired by the films of the Marvel Cinematic Universe (MCU) and real scientific research from around the world.

The process proved to be an incredible adventure. The research part involved reading scientific papers from multiple disciplines and watching the films of the MCU on repeat. I refer to the paper reading process as “academic mining” where I searched through many thousands of papers that could link to the narrative of the book. Some papers were easy to find, some were hard to find. I must admit though that it was a joy to rematch the films once again. Given that the book is based on Tony Stark and his exoskeleton suits, I focused on the films where he had a starring role. For instance, I definitely watched Iron Man (2008) more than 20 times while writing the book. Multiple watches that certainly paid off.

I should emphasise that the book is not about building the Iron Man suit. It is really about building an Iron Person suit – a suit for everyone. I strive to highlight that the technologies within the suit are to be used for good and not for evil. And these technologies need to be developed in an ethical manner, and not in a secretive and secluded manner that mirrors the approach of Tony Stark.The books also acts as my testament to the Marvel Cinematic Universe (MCU) thus far. I use scenes from multiple films to motivate the introduction of concepts and technologies – from Iron Man (2008) to The Avengers (2012) and from Captain America: Civil War (2016) to Spider-Man: Far From Home (2019).

There were plenty of occasions where I didn’t think I’d make the deadline – a deadline that I had set for myself. You see I decided to venture into the self-publishing world one more time with this new book – just like my previous books Secrets of Superhero Science and Secret Science of Santa Claus. Self-publishing can be a challenging task as you need to both write the book and arrange the appropriate support structures for the rest of the book such as an editor, illustrator, proof-readers, and layout designers.

In the end it all worked out and the book arrived from the printers on October 29th 2019, the day before my 40th birthday. The official publication date for the book is October 30th 2019 – a present to myself to mark the end of my 4th decade on the 3rd rock from the Sun. You can get further details on the book here.

Over the coming weeks I’ll write a little more about the writing process and the joys and tribulations of self-publishing.

Until then – always think super!


Five Lessons from Avengers: Endgame

It’s been an emotional rollercoaster for Marvel Cinematic Universe (MCU) fans following the release of Avengers: Endgame, the 22nd film in MCU superhero expanse. Jubilant highs have been intermixed with shocking lows as the remaining Avengers attempted to undo the actions from Avengers: Infinity War of the Mad Titan Thanos. There have been goodbyes for iconic characters, the appointment of new leaders, and the establishment of new teams.

Unsurprisingly, I’ve seen the film a few times (six to be precise and maybe more soon), and every time that I’ve watched Avengers: Endgame, I’ve spotted something new. So here’s the first of five quirky lessons or observations (without giving too many spoilers) from Avengers: Endgame:

1.  Hawkeye Speaks Japanese

One character absent from Avengers: Infinity War was Clint Barton (Hawkeye). After his actions in violation of the Sokovia Accords in Captain America: Civil War, Barton finds himself under house arrest, just like Scott Lang in Ant-Man and the Wasp. In the opening scenes of Avengers: Endgame we see Barton with his family on his farm. We catch a glimpse of the house arrest ankle bracelet as he teaches archery to his daughter Lila. Barton seems at peace as he enjoys spending time with his family. This serenity is destroyed in a matter of moments when Barton’s family are turned to dust by the Decimation (Thanos’ finger snap from Avengers: Infinity War). Barton doesn’t take the loss of his family well and assumes a new persona – Ronin. He goes on a worldwide rampage against organised crime as he takes on criminals in countries such as Mexico and Japan. We see Ronin in action in the latter as it takes out the Yakuza in Tokyo. During a fight with one of the Yakuza leaders, Barton speaks Japanese. Should we be surprised that a spy can speak multiple languages? Probably not.

2. The Creator of Thanos is in the Film

After the Avengers fail to stop Thanos from destroying the Infinity Stones there is a time-jump of five years. It’s the year 2023 and the Avengers are trying to move on. Steve Rogers runs a support group for people who lost friends and family in the snap. One member of the group is Joe Russo, one of the directors of Avengers: Endgame. Another member of the group is Jim Starlin, the comic book artist who created Thanos in the early 1970s. Nice cameo.

3. Steve Rogers is a Terrible Cook

While Steve Rogers runs a support group for people, Natasha Romanoff has seemingly taken charge of the Avengers and their allies. We see Natasha in a conference call with Okoye, Captain Marvel, Rocket, Nebula, and War Machine. She reminds her friends that everything that happens anywhere in the universe goes through her. War Machine is the last to terminate communication, but informs her that an incident in Mexico is more than likely the doing of Clint Barton. After War Machine hangs up, Natasha starts to cry at the thought of her dear friend Barton on a rampage around the world. At that moment, Steve Rogers enters the room and says, “I would offer to cook you dinner, but you seem pretty miserable already.” Despite coming out of the ice more than 10 years before it seems that Rogers has still to learn how to cook a decent meal. Still he must be better than the Vision in Captain America: Civil War!

4. Thor, Korg and Miek play Fortnite

Thanks to the quantum technology and Pym’s particles of Scott Lang and the genius of Tony Stark, the Avengers set in motion a plan to undo the Decimation. But they need a team, so the Hulk and Rocket head to New Asgard, which is located in Tønsberg in Norway, to convince Thor to join the cause. However, Thor has not dealt well with the events of Avengers: Infinity War as he has turned to alcohol and bad eating habits to get over his failure to stop Thanos in Wakanda. In addition to enjoying a few too many beers, Thor also enjoys playing Fortnite, the online video game, with his good buddies Korg and Miek. Interesting way to process his perceived failure to stop the Mad Titan. If he’s been playing Fortnite for five years, we’ve got to assume that he’s probably not bad at it.

5. No mention of X-Men: Days of Future Past

As the Avengers prepare to test their quantum-based time travel technology, a number of characters discuss the implications and rules of time travel. James Rhodes and Scott Lang list a whole bunch of time travel films such as Hot Tub Time Machine, Terminator, Wrinkle in Time, and Bill and Ted’s Excellent Adventure. However, there’s no mention of the 2014 film X-Men: Days of Future Past, in which time travel plays a key role. Of course X-Men: Days of Future Past was produced 20th Century Fox and is not associated with the MCU. But it would have been cool if they had mentioned the X-Men film in the list. On the other hand, it’s likely that the X-Men will become part of the MCU in the near future following the acquisition of 20th Century Fox by Disney.

Within the MCU there must surely be superhero films. Perhaps the adventures of Tony Stark, Steve Rogers, Nastasha Romanoff, and Thor have been made into films within the MCU. This was almost revealed in Guardians of the Galaxy Vol 2. In Marvel Comics, Simon Williams (better known as Wonder Man) is a retired superhero-turned actor. The actor Nathan Fillion (of Castle fame) had been cast as Simon Williams and was supposed to appear in Guardians of the Galaxy Vol 2 on a number of film posters, one of which was for a film entitled “Tony Stark”. Perhaps in the future we will see Wonder Man make an appearance in the MCU, either as a famous actor or as a superhero.


And that’s it, the first five quirky lessons or observations from Avengers: Endgame. Stay tuned for more!

Things aren’t the same after Avengers: Endgame

It’s just over two weeks since the release of Avengers: Endgame, the 22nd film of the Marvel Cinematic Universe (MCU), and the impact of the film has been extraordinary. To date I’ve seen the film FIVE (5) times, and I plan to see the film a couple of more times before it leaves cinemas. Four too many times for some, but for someone like me it’s only the beginning.

I’m more than aware that some people have yet to see the film, which is now the 2nd highest grossing film of all time, so there won’t be any spoilers here from me. I just couldn’t ruin the film for anyone who is waiting for the hype to die down and the theatres to be half empty before they decide to go watch the 182 minute superhero extravaganza.

All I’ll say right now is that the film is fun, exciting, emotional, and there are scenes that will leave you speechless. Of course, like most films these days, there are some things that could have been better, but for me they are minor. To others, these issues are major. In one or two weeks I’ll write a more extensive blog on the film.

Avengers: Endgame – Focused on breaking the box office!

In the build-up to the release of the film, my work on superheroes was featured in a number of publications in the Netherlands. First up my work was featured in an article in New Scientist, in part promoting a talk that I gave as part of the Imagine Film Festival on April 14th. Next, my work was featured in an article written by Nick Kivits for Dutch Men’s Health magazine. I’ve got to say that was very very cool! Finally, Coen van Zwol featured my work in an article with the NRC newspaper.

It’s always great to see articles about my work reach the national press. It’s another thing to see my superhero research make an impact. Of course I cannot take credit for all of the work as I’ve had the opportunity to work with some inspiring students and researchers at TU Delft and further afield.

I promise an in-depth blog about Avengers: Endgame in the near future. But unlike other publications online, this article is spoiler free.

Superhero Scientist to speak at the Imagine Film Festival

Superhero Scientist Imagine Film Festival

Superhero Scientist Barry Fitzgerald at the Imagine Film Festival in Amsterdam, April 2019

It’s been a while since I blogged due to a very busy travel schedule over the last few months as well as a lot of work-related tasks that needed to get done.

Perhaps the best way to reboot the blog for 2019 is highlight an upcoming talk that I’ll be giving in Amsterdam as part of the Imagine Film Festival.  Yes, on Sunday April 14th 2019, I’ll be speaking at the EYE Film Museum in Amsterdam. With so many superhero films due out over the coming weeks and months, it’s an exciting time to be a superhero fan, in particular one who dreams about having superpowers. For the Imagine Film Festival I’ll be covering many superpowers, superheroes, and a whole lot more.

You can check out my interview about my talk right here. Hope to see you in Amsterdam at the Imagine Film Festival.
