Decoding the Universe!

I realised just now that I entirely forgot (it seems) to post about an episode of PBS’ show Nova called “Decoding the Universe: Cosmos” which aired back in the Spring. I thought they did a good job of talking about some of the advances in our understanding that have happened over the last 50 years (the idea is that it is the 50th anniversary of the show) in areas of astrophysics and cosmology. I was a contributor, filmed at the top of Mount Wilson at the Observatory where Hubble made his famous discoveries about the size of the universe, and its expansion. I talk about some of those discoveries and other ideas in the show. Here’s a link to the “Decoding the Universe” site. (You can also find it on YouTube.)

If you follow the link you’ll notice another episode up there: “Decoding the Universe: Quantum”. That’s a companion they made, and it focuses on understanding in quantum physics, connecting it to things in the everyday world. and also back to black holes and things astrophysical and cosmological. It also does a good job of shining a light on many concepts.

I was also a contributor to this episode, and it was a real delight to work with them in a special role: I got to unpack many of the foundational quantum mechanical concepts (transitions in atoms, stimulated emission, tunnelling, etc) to camera by doing line drawings while I explained – and kudos […] Click to continue reading this post →

The Life Scientific Interview

After doing a night bottle feed of our youngest in the wee hours of the morning some nights earlier this week, in order to help me get back to sleep I decided to turn on BBC Sounds to find a programme to listen to… and lo and behold, look what had just aired live! The programme that I’d recorded at Broadcasting House a few weeks ago in London.

So it is out now. It is an episode of Jim Al-Khalili’s excellent BBC Radio 4 programme “The Life Scientific”. The show is very much in the spirit of what (as you know) I strive to do in my work in the public sphere (including this blog): discuss the science an individual does right alongside aspects of the broader life of that individual. I recommend listening to […] Click to continue reading this post →

What a Week!

Some Oxford scenesI’m sitting, for the second night in a row, in a rather pleasant restaurant in Oxford, somewhere on the walk between the physics department and my hotel. They pour a pretty good Malbec, and tonight I’ve had the wood-fired Guinea Fowl. I can hear snippets of conversation in the distance, telling me that many people who come here are regulars, and that correlates well with the fact that I liked the place immediately last night and decided I’d come back. The friendly staff remembered me and greeted me like a regular upon my return, which I liked. Gee’s is spacious with a high ceiling, and so I can sit away from everyone in a time where I’d still rather not be too cavalier with regards covid. On another occasion I might have sought out a famous pub with some good pub food and be elbow-to-elbow with students and tourists, but the phrase “too soon” came to mind when I walked by such establishments and glanced into the windows.

However, I am not here to do a restaurant review, although you might have thought that from the previous paragraph (the guinea fowl was excellent though, and the risotto last night was tasty, if a tiny bit over-salted for my tastes). Instead I find myself reflecting on […] Click to continue reading this post →

A Dialogue about Art and Science!

Comments Off on A Dialogue about Art and Science!

On Saturday (tomorrow), I’ll be talking with science writer Philip Ball at the Malvern Festival of Ideas! The topic will be Science and Art, and I think it will be an interesting and fun exchange. It is free, online, and starts at 5:15 pm UK time. You can click here for the details.

I’ll talk a little bit about how I came to create the non-fiction science book The Dialogues, using graphic narrative art to help frame and drive the ideas forward, and how I really wanted to re-shape what is the norm for a popular science book, where somehow using just prose to talk about serious scientific ideas has become regarded as the pinnacle of achievement – this runs counter to so many things, not the least being the fact that scientists themselves don’t just use prose to communicate with each other!

But anyway, that’s just the beginning of it all. Philip and I will talk about […] Click to continue reading this post →

Reunion

Revisiting an old friend you might recognize. (And discovering that my old inking/shading workflow was just fine. – I’d been experimenting with other approaches and also just getting back into the saddle, as it were. I’ve found that I’d already landed on this approach for good time-cost/benefit reasons.) -cvj

Conjunction

But… while the viewing on the 21st (the peak of the conjunction) was perfect, seeing three of the Galilean moons, and the glorious rings of Saturn, very clearly, getting a decent through-the-lens photo was not so trouble-free. I was dissatisfied with the roughs of the photos I got that night, with lots of blurring and aberrations that I felt I should have been able to overcome. So I spent the next day taking the telescope entirely apart, checking everything, and trying to colimate it properly, and testing schemes for better vibration stabilisation of the camera. I was ready for another session of photographing the next night, but it was cloudy, with only about […] Click to continue reading this post →

This Feels Great!

[caption id="attachment_19729" align="aligncenter" width="499"]Andrea Ghez accepting the 2020 nobel prize for physics Andrea Ghez accepting the 2020 Nobel Prize for Physics[/caption]You know, it is easy (and healthy) to be steadfastly cynical about the whole prize thing, but sometimes it is just great to simply cast that aside and get into the spirit of it. This is one such time. The Nobel Prize ceremony was today and you can watch the whole thing on YouTube here. (Physics starts at about 36 minutes in.) My interest was in the moments Andrea Ghez and Roger Penrose picked up (literally this year) their prizes for their wonderful work on black boles. The picture I was able to screen grab of Andrea in particular says it all.

I’ve met Andrea Ghez on an number of occasions (and communicated electronically on many more), usually because of our joint interest in making science accessible to the public through talks (where we first met during K C Cole’s excellent Categorically Not! series), TV shows (where we’ve sometimes connected behind the scenes, in the context of shows or films we’re both in, or thinking of being in), and so forth. All our interactions have been […] Click to continue reading this post →
