Corrections: 4:53 This isn't a fair comparison. Actually, if you changed the mass of the hanging masses in the experiment, it WOULD change the deflection angle. That's because the value of T in the equation would change. The torsion pendulum would oscillate more rapidly with lighter masses. Thanks James Gilbert.

The Finite Element Method/Analysis is an incredibly powerful way to model the real world. By discretizing a continuous medium you can accurately simulate the real world. Simulating a living organism like the heart is really challenging because you have to add things like electrical conductivity to your model. But perhaps more challenging is to bring together all the experts from different disciplines. But it has finally been achieved.

A solution of sugar water can actually change the orientation of polarised light. Glucose/dextrose always twists light to the right! It's all to do with the superposition for quantum states and the chirality or handedness of sugar molecules.

Most of the coal on earth was created during a single short period of geological history 300 million years ago. It's called the carboniferous period. Find out why coal production stopped so abruptly. CORRECTIONS So this video was quite rushed because I wanted to get it out in time for the #teamtrees launch. Here are a couple of things I got wrong: Not ALL coal was made during the carboniferous period. There exists some younger coal here and there that formed under rare conditions that enabled it in spite of the presence of capable fungi. I did film myself saying that but it was lost it my rushed edit. Photosynthesis is more complicated than I described. It involves water for a start. And it seems that the oxygen released during photosynthesis comes from the H₂O not the CO₂. Though I haven't be able to verify that. And here's a non-correction! The thing I was holding up at the start was not charcoal. It was a coal dust briquette. You could argue that the briquette was made recently but the coal it's made of is old! So yeah, the thrust of the video still stands but it's been a learning opportunity for me! A final thought on planting trees for carbon capture. A lot of comments saying "what's the point? When the trees die the decomposers will release the CO₂ back into the atmosphere. But really this is more about planting *forests*. In a forest, when a tree dies, another tree grows in its place recapturing the carbon. But also, it's my understanding that it takes a very long time to release the CO₂. Like hundreds of years. So in terms of tackling climate change which is a problem of human time scales, it's a useful endeavour.

The size of the grains affects the physical properties of the metal, like hardness, toughness, strength, mailability, ductility, plasticity. Heating a metal can change the size of the grains. This ball bearing model demonstrates annealing. Ductility is dependent on how far dislocations are able to travel in the metal which is dictated by grain size.

Horizontal gene transfer allows bacteria to swap genes, these speeds up the acquisition of new traits like antibiotic resistance. There are 3 main mechanisms: transduction, transformation and conjugation. But where are human pathogens picking up these genes? In our bodies? In rivers and oceans?
