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 take a good image? So many questions, but the au

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's see the likelihood for each with each piec

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 feel these concepts are so abstract - unless on

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 hard to grasp the generalization from only a couple of s

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 really the map of bundles of major highways in the brain, as MRI

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 function which reflects the structure of the new job, the

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 power, will cost $0.1/hour in electricity bill alone at whe

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 is controlled by dictators. Life sucks over there

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, with a perfect understanding of electronic principle, a rud

"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 think worth controlling, and in reality you never k

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 important is rate of metabolism - higher metabolism, highe

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 complex and we know so little about it, so that the normal logi

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 push it forward, which will hurt the power players hard (espe

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 built and owned by the government, the economical

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 a huge headache to the airlines, which leads to some health

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 an extensive railway network. The first step is to run the b

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. Maybe if the code have different structure, some 'visual&#x

Just to be pedantic: Each of the data points is an average of many users (and potentially have huge errorbars they do not show). Therefore for single individuals, this result may not be very predictive. In fact, given that the distribution

I always wonder why some disciplines are more open than others [0]. As someone in biology: the state of publication is very sad. We have to pay thousands to _submit_ a manuscript, and then: - get rejected right away, or - the manuscript get
