I don't get it. Where is the spec? What's the aperture size, focal length of this beast? What about abberations? How does it work in extreme conditions that a normal lens can't tak…

I guess different people have different definition for "significant circumstantial evidence". We have two hypotheses: 1. virus come from seafood market, 2. virus come from lab. Let…

Being someone who is still struggling with these concepts, I like this tutorial because at least it doesn't use the common list/maybe/state to illustrate the concepts. Somehow I fe…

Digging down a bit this method is published in Nature! https://www.nature.com/articles/nature21054

I am still pretty new learning haskell, and find this very helpful. Not necessarily agree whether monadic solution is prefered, but I like how it shows how general monad is: it's h…

Just to clarify, these MRI images looks at white matter, which are mostly bundles of long-range myelinated axons. This is more likely a map of major highways in the brain (Or reall…

I think it really depends on the task. We are just hijacking the brain machinery to do jobs it is not evolved to deal with. If we can find some highly evolved / optimized brain fun…

I have thought about the same thing when playing with deep learning at home, until I put electricity bills into the equation. A beast like what the author has built, with full powe…

I spent almost equal amount of my life in China / North America now, it's interesting to see and compare what one side think about the other. In north America, what I get is China …

One question to ask is then: what method is useful to figure out the function of an unknown microprocessor? The engineers sometimes reverse engineer chips with electron microscope,…

> I still fail to see why having a single neuron that circumnavigates the brain should lead to consciousness. The number of neurons you can trace is limited by the methods: traditi…

"all you have to do is read the methods section in the paper and follow the instructions." I wish science was that simple. The methods section only contains variables the authors t…

I have a wild theory about longevity. For all the mammals, increased heart rate correlates with lower life span [0]. But heart rate itself may just be a measurement, and what's imp…

For many assertions, my quick filter is: what the _direct_ experimental design would look like to draw such conclusions? Is it possible that it is done somewhere? Biology is so com…

Maybe I should explain better. I think with a project receiving so much opposition both from the government and citizens, I imagine Liu would have to use extraordinary methods to p…

It's a very fine line to walk though: too much profit, people hate it (it's taking money from them), run at a loss, people hate it (it's a waste of tax money). But since it is buil…

The ticket price of the bullet train is usually cheaper than by air (and the train is much, much more convenient than flights), and affortable by average citizens. This has created…

As someone who grew in China, I just want to point out that besides the engineering, it is a political wonder as well. Before the bullet train network was built, China already has …

I think you nailed an important point here: text is great in representing code because text is sequential, and so does a lot of the code we write, and the computer it runs on. Mayb…

If anyone like me thinks all these visualizations just make the code more confusing, I want to point out it might be a personal (although it can be very strong) preference. I alway…
