Max Cooper's Ascent — Making of the Music video
Enter the 5th dimension
contents
Here, I show some early prototype scenes generated from the animation system during development and testing. There was a lot testing.
These scenes are short and evolve slowly. They built from keyframes (but fewer) in the same way as the final Ascent video.
The animations here have no audio.
A cube evolves from 2 to 8 dimensions. The colored lines in the center show the unit axes. This scene served as the inspiration for the start of the Ascent video. The scene ends with the dimensions shrinking back to zero, one at a time. Notice the variety in the complexity of the projected scene as we rotate through various angles.
One of my favourite scenes. Cubes are added to the scene as the camera zooms in. The lines are formed by the area maps of digits of `\pi` projected onto faces of the cubes. Each scene evolves with one additional dimension added.
A variety of short scenes in black-and-white and color. Rectangles correspond to area maps on the faces of the cube, color-coded by digit.
Area maps projected onto cubes with transparency encoding the z-position (distance from camera).

Propensity score weighting
It is not certain that everything is uncertain. —Blaise Pascal
We have already explored how we can mitigate bias caused by confounding variables in observational studies using propensity score (PS) matching (PSM) and propensity score weighting (PSW). However, any statistical model is only as good as its assumptions and, if it is specified incorrectly, it can itself produce biased estimates of the treatment effect.
This month, we explore double robustness, a powerful statistical concept that provides a valuable “safety net” against the risk of an incorrect model. It offers two opportunities, instead of just one, to obtain a valid estimate of the treatment effect — making it possible to draw credible causal inferences from observational data without having to depend on a single set of modeling assumptions.

Nature Biotechnology cover
My cover design on the 7 April 2026 Nature Biotechnology issue shows the dendrogram that represents a cluster of uniquely expressed (or downregulated) genes in human naive stem cells induced from such cells. Within each dendrogram block, the genomic barcode sequence (sampled from Supplementary Table 1) is depicted with a Code 39 barcode. The highlighted barcode is one of those used for cell isolation.

Ishihara's Tests for Colour Deficiency

Symmetric alternatives to the ordinary least squares regression
What immortal hand or eye, could frame thy fearful symmetry? — William Blake, "The Tyger"
This month, we look at symmetric regression, which, unlike simple linear regression, it is reversible — remaining unaltered when the variables are swapped.
Simple linear regression can summarize the linear relationship between two variables `X` and `Y` — for example, when `Y` is considered the response (dependent) and `X` the predictor (independent) variable.
However, there are times when we are not interested (or able) to distinguish between dependent and independent variables — either because they have the same importance or the same role. This is where symmetric regression can help.

Beyond Belief Campaign BRCA Art
Fuelled by philanthropy, findings into the workings of BRCA1 and BRCA2 genes have led to groundbreaking research and lifesaving innovations to care for families facing cancer.
This set of 100 one-of-a-kind prints explore the structure of these genes. Each artwork is unique — if you put them all together, you get the full sequence of the BRCA1 and BRCA2 proteins.
