Twelve minutes into the pilot episode of the 1970s TV series, The Amazing Spider Man, a young Peter Parker, played by Nicholas Hammond, is bitten in a lab by a radioactive spider. Moments later out on the street, his brand-new spidey sense already tingling, he is chased by a car to the end of a blind alley. Without thinking, he launches himself onto the smooth wall and effortlessly climbs several storeys 鈥 much to his own surprise.

I was 6 or 7 years old when I saw this for the first time, and it blew my tiny mind. Rewatching today gave me a physical shiver of nostalgia. Those moments were my gateway drug into Stan Lee鈥檚 comic-book world. Four decades later, it鈥檚 an entire Marvel Universe, and one which Lee sadly left on 12 November, aged 95.

Lee鈥檚 decades as Marvel鈥檚 top writer and editor helped to revolutionise comic-book superheroes and villains. Much of his success came because he focused on depth of character as much as spectacle. Sure, his characters had cool superpowers, but they also had flaws, and personal difficulties to deal with.

Peter Parker鈥檚 adolescent angst, David Banner鈥檚 anger management issues, Tony Stark鈥檚 battle with alcoholism. As often as not, his heroes鈥 powers caused them great personal difficulty 鈥 yes, Hulk, I鈥檓 looking at you 鈥 making them more relatable, and attractive to a wider audience.

Captain diversity

In the 1960s, Lee was instrumental in increasing聽diversity in superhero characters, says psychologist and mental health counsellor Parker Shaw, based in Tulsa, Oklahoma, who has researched the psychological effects of reading superhero comics. 鈥淢ost people had a superhero that looked like them, and struggled with the same challenges,鈥 says Shaw. 鈥淪tan鈥檚 contributions of diverse characters allowed a larger audience to feel recognised, valued, and understood.鈥

Today, Shaw sometimes uses comic book narratives in therapy. 鈥淎s a mental health counsellor, I am trying to connect with my patients in a way that both of us can relate to. Superheroes offer a safe, relatable outlet for children, adolescents and adults to openly discuss superheroes鈥 struggles, while indirectly processing their own struggles.鈥

Radiation 鈥 is there nothing it can鈥檛 do?

Tributes have been pouring in for Lee. The current Hulk, Mark Ruffalo, : 鈥淵ou let us be extra human鈥 superhuman even.鈥 And that 鈥渆xtra human鈥 was a key to Lee鈥檚 success. While DC comics served up superheroes often destined for greatness (think Superman and Aquaman), Lee took everyday people, and thrust superpowers upon them, often courtesy of, let鈥檚 face it, some very dubious science. Where would Lee be without radiation?

A radioactive spider created Spider-Man, exposure to gamma radiation produced the Hulk, while cosmic rays turned four astronauts into the Fantastic Four. As Lee admitted in : 鈥淚鈥檓 the least scientific person you鈥檒l ever know, but I try to seem scientific with our characters. I wouldn鈥檛 know a gamma ray if I saw it鈥 But if it sounds good, I鈥檒l use it.鈥

But perhaps Lee was being too self-deprecating. From artificial silk with curious properties (though unlikely to catch thieves just like flies), to power-lifting exoskeletons (though without Tony Stark鈥檚 jet boots 鈥 yet), the futuristic technology that features in many Marvel creations may be just around the corner.

As well as his extraordinary creativity, Lee鈥檚 own superpowers included his longevity. 鈥淚 was first interviewed for Stan Lee鈥檚 obituary about 20 years ago,鈥 writer. 鈥淚 was happy he defied the reaper and carried on. With Stan gone, an era really does come to an end. He was the happy huckster that comics needed. And he really did alliterate like that when you talked to him.鈥

Perhaps Chris Evans, who plays Captain America, summed it up best, ending with Lee鈥檚 own trademark sign-off: 鈥淭here will never be another Stan Lee. For decades he provided both young and old with adventure, escape, comfort, confidence, inspiration, strength, friendship and joy. He exuded love and kindness and will leave an indelible mark on so, so, so many lives. Excelsior!!鈥

Melanie Windridge鈥檚 company has heated plasma to sun-like temperatures
Fusion could solve the world鈥檚 energy problems and curb climate change, says physicist and Everest-conquering adventurer Melanie Windridge, who reveals some of the latest innovations. What inspired you to get into fusion energy as a career? When I realised that it could solve the world鈥檚 energy problems if only we could do it, and that it would decarbonise our energy system, helping to curb climate change. And that was just for starters. What does your work involve? I work with a fusion start-up called , which is aiming to show the commercial feasibility of fusion by 2030. We have an experimental machine called the ST40, which is a spherical tokamak. Tokamak reactors are the best performing fusion device that scientists have come up with so far. The reaction chamber is a torus shape, a bit like a ring doughnut, though ST40 is squashed up like an apple. The world鈥檚 biggest fusion reactor, ITER, being built in France, is a tokamak machine, but we want to use advanced superconducting magnets to bring the size down.
How do we get fusion energy? 快猫短视频s have already achieved fusion. It鈥檚 just that no one has yet got more energy out of the reaction than they put in 鈥 quite important if you want to make a power station! To do it, we first have to create the conditions that are found inside of stars. In fact, even hotter than that, because we want to use a slightly different reaction that won鈥檛 take millions of years to get going. 100 million 掳C is the threshold we鈥檙e looking to reach, to get fusion going. We may even operate at 150 million 掳C or more. Then, of course, you need to contain that plasma, that hot fusion fuel. Magnetic fields are used for that. How close are you to creating star-like conditions? This year, we hit 15 million 掳C, though I was on Mount Everest at the time. That temperature milestone was really good news 鈥 that鈥檚 hotter than the sun. To heat the plasma we used an experimental technique called merging compression 鈥 joining two rings of plasma and then compressing it with an intense magnetic field. We didn鈥檛 have any external heating from things like neutral , which is an additional way to heat plasma. We鈥檙e now starting to upgrade to use neutral beams; we want to achieve 100 million 掳C in the next year or so. If the magnetic field fails to contain superheated plasma, what happens to the machine? This is a really good thing about fusion energy. It鈥檚 inherently safe, because there鈥檚 so little plasma in the machine at any one time. If you lose control of it, there鈥檚 not enough fuel there for a big explosion or anything catastrophic. It would simply cool very quickly, though that can put strain on the machine structure. When are we likely to see fusion power become a reality? Science is an exploration and we don鈥檛 know what we鈥檙e going to find along the way, but I think I could speak for the whole fusion community when I say we want it as soon as possible. At Tokamak Energy we鈥檙e aiming for the 2030s. What innovations will improve fusion? One thing is high-temperature superconductors. They can operate at around 76 degrees above absolute zero 鈥 about -200 掳C 鈥撀 instead of about 4 degrees above absolute zero, which is what conventional superconductors operate at. Tokamak Energy is developing high-temperature superconductors for fusion, though we would still cool them to between about 20 and 30 kelvin (-256 掳C and -246 掳C), because their performance is better in that range. It鈥檚 a fivefold energy saving compared with conventional superconductors, and they produce stronger magnetic fields. The world鈥檚 biggest fusion reactor, ITER, is due to start up in 2025. What can we expect? They are aiming to get about 10 times more energy out of the fusion reaction than they put in. That will prove fusion energy is possible. ITER is going to test other systems as well, because ultimately, fusion is just a heat source, and once you start developing experimental reactors into real power stations, you need lots of other systems 鈥 like how do you extract that heat energy? There鈥檚 still lots to do then? Loads to do, yes. But it鈥檚 not intractable: there are clear steps along the pathway and things that we need to do. Humans have done incredible things 鈥 we鈥檝e flown to the moon, for goodness sake. It just takes money, people and time. But the politics takes its toll. ITER, for example, has been hugely delayed because it turned into a big political thing. It鈥檚 a worldwide collaboration, which means it鈥檚 bureaucratic, really slow and inefficient. Before the delays and inefficiencies with ITER led the costs to spiral, one country could have built it for less than it costs to run the Olympics. Now, everyone鈥檚 quite happy for one country to run the Olympics, but apparently nobody wants one country to solve the world鈥檚 energy problem. You seem to enjoy tough challenges in life as well as science. Congrats on reaching the summit of Mount Everest in June. Thank you! I was really lucky to have such a positive experience up there. 聽I arrived at the summit with my Sherpa partner at 4:30am, just as the sun was coming up. We were the first of the day to arrive, which is amazing, because it meant that I had this really pure experience. We spent almost an hour there alone. What prompted you to go to Everest? I loved mountains already, but five years ago I read the 1953 book The Ascent of Everest by John Hunt, and I realised that the main reason that the British got up in 1953 and had failed in previous decades, was mostly to do with the scientific understanding and the technology that was available. I am really interested in science and exploration and how they drive each other. 鈥⒙ is a physicist, speaker and writer.
