Energy Savings of Flying in a V-Formation Using Lego Models

I got the idea for this experiment from a great Science Buddies page, which suggested using Lego bird models to investigate the optimum position for flying in a V-formation. Hypothesis I hypothesised that the optimum position for the leading bird (that with the least amount of drag on the following bird) would be quite close … More Energy Savings of Flying in a V-Formation Using Lego Models

Data analysis: road fatalities part 2 – by date

By Joel Johnson Although the road toll for a particular day of the year is somewhat stochastic, it would be expected that some days have a higher fatality rate, and some days have a lower rate. Factors such as school holidays play a large role. This investigation seeks to determine the most dangerous and safest … More Data analysis: road fatalities part 2 – by date

Elucidating the mechanism of twisting action in black speargrass awns

Below is a report about my observations of how black speargrass (Heteropogon contortus) twists when wet. It is an intriguing behaviour, and I don’t believe there are many scientific papers on the topic.   Elucidating the mechanism of twisting action in black speargrass awns By Joel Johnson ABSTRACT Black speargrass awns were found to increase … More Elucidating the mechanism of twisting action in black speargrass awns

Saxon Water Bowls

Saxons are reported to have used bowls with a small hole in the base, placed in a larger bowl of water, to limit the length of their orations (Richard Walding’s Senior Physics page). The size of the hole determined the time taken for the bowl to sink. It could be expected that the time taken … More Saxon Water Bowls
