Biofuels can be chemically altered raw materials that have been grown by living things, which include grains, wood and algae. Currently, biofuels made from algae are becoming somewhat less problematic than biofuels made from grains and wood, in terms for the environment. #Physics

David McCauley’s iconic mammoths have explained #engineering for decades, starting with The Way Things Work. Now 78, the illustrator’s works are featured at the National Building #Museum. His latest project, inspired by walks with his late dog Stella, encourages readers to see beauty in everyday structures like fences and fire escapes. 📚✨

Why Nature Loves Fractals

Trees, blood vessels, and rivers all follow branching patterns that make their pieces look very similar to their whole. We call this repeating, self-similar shape a fractal, and this Be Smart video explores why these branching patterns are so common, both in living and non-living systems. For trees, packing a large, leafy surface area onto the smallest amount of wood makes sense; the tree needs plenty of solar energy (and water and carbon dioxide) to photosynthesize, and it has to be efficient about how much it grows to get that energy. Similarly, our lungs and blood vessels need to pack a lot of surface area into a small space to support the diffusion that lets us move oxygen and waste through our bodies. Non-living systems, like the branches of viscous fingers or river deltas or the branching of cracks and lightning, rely on different physics but wind up with the same patterns because they, too, have to balance forces that scale with surface area and ones that scale with volume.

Why “city-killer” asteroid YR4’s impact probability keeps increasing Yes, the probability of asteroid 2024 YR4 striking us has increased: from 1.2% to 2.3% to 2.6% to 3.1%. It'll keep going up, to around ~5%, before its odds plummet to 0. Here's why. bigthink.com/starts-with-... #space #physics

What measures that target women and girls in science would you care about and/or would you like to see realized in the scientific community?

“It’s hard to choose particular measures because I consider that an issue that needs to be addressed on a global scale. In any case, I think there should be more measures that take care of family support, reducing possible biases in evaluation processes and having an effective protocol of support when there are complaints about a situation of discrimination.”

Last Summer, my student intern Scarlett Spackman put together a great document about accessible teaching for #maths, #stats and #physics.
Under two headers, "Why should I care?" and "Advice", Scarlett makes the case for improving accessibility and then offers practical ways of achieving that.

I've finally got the go-ahead to share it more widely:

What is your vision for women and girls in science in 20 years?

“In 20 years, I strongly believe that the female community in science will be more represented. Nowadays, society is already exposing young girls to STEM fields more than it did in the past, for instance, through toys and cartoons. Moreover, for the older girls, the increasing visibility of female scientists as role models is inspiring and necessary to imagine themselves in the same positions.”

"Electrons are everywhere. But what if it's the same one?" 😎🤭🤣

"It's estimated that there are around 1082 atoms in the observable universe. With each element in the periodic table containing at least one electron, you can therefore safely assume there are at least 10,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 electrons in the observable universe as well. Or can you?"
