Active fires

Posted on

I worry a lot about the climate changes and the loss of biodiversity on Earth. NASA have a lot of maps (based on satellite images) that show changes on the Earth. For instance, they have maps that show active fires year by year (back to year 2000). So I made this animation of the rotating Earth – first with night lights to show the location of human citites – and then with active fires in august 2021. I was surprised – and sad – that it was so many places!

Inge Lehmann GIF by Ann-Louise Bergström

Inge Lehmann was a Danish seismologist and mathematician, who discovered that the Earth has a solid inner core. She did this through studies and calculations of the spreading of seismologic earthquake waves. She was an amazing woman, but despite her extraordinary talent and great findings, she is almost unknown in Denmark. First after she (in her mid-60ies)  had moved to perform research at Columbia University in US,  she was acknowledged accordingly by the international research community.

She was truly a pioneer – having to struggle in a male-dominated academic world, where women were yet not welcome. Although they could attend universities (at least in Denmark), they could not get academic positions. Inge needed to perform much of her research in her spare time and vacations (in contrast to her relative Niels Bohr, who lived in the same period).

She lived to be 104 years (!) and managed to see her theory about the Earth’s inner core be confirmed by computer calculations. I have made this GIF (of combined 2D and 3D-art) as a tribute to her.

Global Warming

It’s getting warmer…

Since 1880, the average temperature on Earth has increased – how much, depends on how it is calculated. During the same period, the global sea level has increased with a rapid pace. Moving Science has made an animated visualization that shows the annual anomalies (thus, how much the average, annual temperature for land and ocean diverges from the 19th Century normal) year by year – combined with sea level data – from 1880 to 2020.

Go to data-visualizations to see the full animation.

Many thanks to Brian Dall Schyth, Karen Gunn and Naja Edvards-Krenchel for valuable feedback and good discussions!

Talk at Danish Science journalists

Posted on

I recently gave a talk about how to use visual effects (like animations and illustrations) when communicating science at a meeting for the Danish Science journalists (“Danske videnskabsjournalister“). I did this together with my collaboration partner Brian Dall Schyth. Like myself, Brian has a background in biology and science, which he makes good use of in his company ExplainWays, where he offers (mostly handdrawn) illustrations.

During the talk, I showed (in fast motion) how I work when I 3D-model an object – the example was this adenovirus particle.

COVID-19 vaccines

Posted on

In many countries – at least in Europe and North America – a large proportion of the population has been vaccinated against COVID-19. In Denmark, the vaccines that have been used are the ones from BioNTech/Pfizer, Moderna and AstraZeneca (the latter has however been discontinued). The two first ones use mRNA-based technology – the last one vector/DNA-technology. But how do they actually work? And what are the differences – and similarities? Watch this animated explainer, that I have made in collaboration with the genetics expert Lasse Folkersen.
