>Penrose ultimately showed that singularities are inevitable, with the implication that black holes are common in the universe. I'm not familiar with the proof. Did he show that in the THEORY of general relativity, singularity has t

If I understand correctly, this is more like an experimental milestone towards an photonic approach to QC. The system is not programmable and cannot be consider as a computer. The article sounds more like the team has demonstrated construct

Not sure about if this is really science. Physical formula are derived from known physical laws in order to understand the original of the phenomenon. If theorists are allowed make up arbitrary formula of course it can fit the data with les

When he said training on Google colab took one day and on his computer took 20 mins, did he compare with google colab CPU? The difference seems too large.

agreed. More physicists (but not all) should be doing something like this. This is what tenure system for.

I believe it is not correct. You can put new features that do not exist in the physical world in a simulation. For example, you can double the number of quarks in a proton as long as you define a mathematically consistent interaction to all

Occam's Razor is a good principle for choosing scientific hypotheses. But I think when it comes to studying big questions like fundamental fabric of this physical world, we are at a lost here. Essentially we elect to believe, without j

I guess that's the gist of all these arguments -- they are ideas not something we can prove or disprove.

I actually think his explanation is right on. Physicists are practical. They make model to quantitatively describe their experiments. Understanding fundamental truth is kind of a by-product. They generally follows a reductionist approach, s

Abott's test is cartridge based, isothermal and modular. There should be no technical reason why they cannot build a high throughput, random access version. Whether this is the direction the company wants to spend their resources is an

Hi, I read through your paper. Interesting method. In figure 1A, the workflow includes a standard PCR step before Sanger. Workflow-wise, wouldn't it still have the same bottleneck as qPCR test, i.e. limited by 96/384-well instrume

Finally some sanity from CDC. Early on there's evidence that people got infected but they didn't know it, yet they can infect others. The only logical conclusion is everyone should wear mask. See the Asian countries that are doing

This is PCR test. Antibody test generally has lower sensitivity i.e. higher false negative rate because PCR amplifies target molecules.
