Shameless plug, but I work on a multispectral lidar that does produce “colored” point clouds in the SWIR [0].

It is pretty cool, we use it for detection of humidity degree or for species discrimination (e.g. plants, minerals, chemicals…).

SpaceX works on (potentially) military techologies covered by ITAR protection.

Diversity goes beyond skin color.

I guess this thread discusses 2nd order effects. The most important factors are still the food you eat (Mediterranean diet in this case) and the number of calories (portion sizes).

We use a similar method to simulate 2D atmospheric turbulence for adaptive optics simulations in astronomy. The structure of turbulence is described by an analytical power spectral density function (classically Kolmogorov spectrum). We generate random coefficients in the Fourier space and then weight them by the PSD. After an inverse Fourier transform we obtain a beautiful draw of turbulence with the desired spatial structure.

Well, senior people earn more and have an easier life. This is not necessarily bad. Young people don't need to have an easy life, just a fair one, with equal opportunities to those ones that came before them and the ones that are among them.

Thank you for the references, this is a very interesting perspective that I personally never considered before.

But still, I wondering if this should mean that WFH needs to be enforced at any company. Not every company can implement full WFH without disrupting operations, especially when working with hardware or when needing concurrent comunication between co-workers.

The article about black workers, mentions discrimination based (mainly) on their appareance. Sure this cannot happen if they work behind a screen. But the same would happen if we all were blind? Shall we wear opaque glasses to end discrimination based on racial features too?

We can also flip the argument. I see this as telling black people (or other groups), stay at home, and in this people will not discriminate you. Is this really what we want? We should make the world better by improving it, not downgrading it.

No, but any physically impaired person will have a disadvantage in any physical environment. You cannot always lower the baseline to allow all persons to do the same in the same conditions.

By this reasoning, we should also close all physical stores, since wheelchair users have more difficulties to buy bread in person. If for the majority it is easier to go in person to buy bread, I think a better compromise is to adapt the shop to as many people as possible, while accepting that access will be still more difficult for some.

Could you, please, give your point of view on it? This is something I never thought about.

By "superbacteria" I mean "drug-resistant bacteria".

I linked the original study, but I saw it Spanish national media, and then here: https://edition.cnn.com/2022/01/19/health/bacterial-antimicr...

The problem is that high performance optical systems are expensive.

There are physical limits that forces them to have big mirrors and other expensive and relatively bulky optical elements. Also, there is no mass production due to small batch sizes (typically one or two).

So if they have a two year life span, it will not be economically viable.

Cymer (acquired by ASML) is the company providing the 13 nm light sources for the EUV machines of ASML.

Not the OP, but I guess he is talking about the hypertelescope concept: https://hypertelescope.org/hypertelescope-en/

For additional background, there are already optical interferometry telescopes in use, see VLTI by the European Southern Observatory (Chile, shared facility with the four VLT telescopes and some smaller telescopes).
