Some pieces and bits

It’s early January. That time when other people’s New Year’s resolutions mean that you get lots of emails. About really important stuff that you simply must deal with, like, immediately. These folks need a reply because they only have stamina for a few days’ frantic emailing. After the New Year energy burst, they lose all energy and then you don’t hear from them again until next year. It’s like the Monarch Butterfly migration — all flapping and fluttering and in-your-face attention-grabbing and suddenly…well suddenly it’s all over and off they disappear for another twelve months.

This year I avoided posting about science at Christmas or reviewing what amazing science-related things happened in the year gone by. Daringly, I felt compelled to ignore the clichés. (That, and I was busy, trying to finish a book no less (more on which coming soon…)).

So in tidy-up mode I was going to post something about a forthcoming public talk. But before I did that I felt it would be good etiquette to post the slides from my last public talk, from Science Week back in November. So here they are:

Like the Pony Express, I always deliver.

Happy New you-know-what!

Headline-spectrum of the day: Dino-apocalypse by ‘wind’

So apparently, the dinosaurs are extinct. That’s not really news of course (time to let it go, Nessie fans). But what is making the news is some new research about how those terrible lizards ended up shuffling off this mortal coil en masse.

There is quite good geological evidence that some kind of massive catastrophic event occurred around 65 million years ago, pretty much around about the same time that dinosaurs stopped appearing in the fossil record. Most kids today will tell you that this was caused by a large asteroid (a theory known as the Alvarez impact hypothesis), but some scientists argue with these kids and believe instead that those geological remnants are not inconsistent with multiple asteroidal impacts, or perhaps with the world’s biggest volcano going ‘pop’ (or something).

A dinosaur earlier this year. Obviously.

But today we saw reports offering an alternative theory. Continue reading “Headline-spectrum of the day: Dino-apocalypse by ‘wind’”
