    On Tuesday, in my class, we have learnt that all a neural net does is stretching / contracting the space fabric. For example this 3-layer net (1 hidden layer of 100 positive neurons) gets its 5D logits (2D projections) linearly separable by the classifier hyperplanes (lines).

    Viruses are closer to tiny biological machines than to living organisms. This great animation shows how a virus reproduces by hacking cells and getting them to replicate their 🧬.

    it’s not a small sample size, it’s small-batch, artisanal data

    We test The Portal for the first time in Episode 19. In some sense, the Podcast just started. I believe this may be the first time my brother and I have appeared together in public without others. Hope you find it interesting.

    "A university's job is only to teach people how to think, not what to think" sounds great until you realize what an awful waste of everyone's time it would be to make students figure out millennia of accumulated knowledge starting from first principles.

    The similarity between the left-right pairs of neurons is really astonishing.

    Plot of a p-value, calculated for a simple t-test, for sample sizes of 10 to 2010, when the null hypothesis is true. Because p-values are uniformly distributed, the p-value just wanders randomly between 0 and 1. This is why repeatedly analyzing data as it comes in is not good!

    A Roman Catholic church in rural Louisiana has come up with a way to maximize its blessings: filling up a crop-duster plane full of holy water and misting the entire community. "We can bless more area in a shorter amount of time," said one reverend.

    The only argument against evolution is how bad children are at hide-and-seek. You'd think there would be tremendous selection pressure against being told 'Now you go hide in the kitchen' and doing this:

    Serious startup idea: 'hearing aids which are better than normal ears'. This is a huge opportunity between dereg of hearing aids, deep learning signal processing+ASICs, steady battery life improvements, world aging, & Apple making Airpods cool. Young people just don't get this.

    There seems to be an unstated assumption among neuroscientists that any viable theory of consciousness must be reducible to a three-letter acronym.

    People are biased. Data is biased, in part because people are biased. Algorithms trained on biased data are biased. But learning algorithms themselves are not biased. Bias in data can be fixed. Bias in people is harder to fix.
