Boring real answer: stars in an image. It’s a robust pre-opencv image processing tool for astrophysics.
See also SAO Image DS9, which was the subsequent version after SAO Image Next Generation.

Oh! That’s nice to know about mining, making it safer for workers! But there’s still the environmental impact… A few years ago, I was talking with a mine engineer who seemed proud to say that they had to move a lake to mine. He claimed that simply shop-vaccuming fishes from one place to the other was good enough…

This is bad popular science. Look at PBS Spacetime for a better way if doing it.

It’s clean regarding chemical waste.
I’ve helped build nuclear waste caskets, nothing is perfect but the amount of attention put into making it safe is incredible! The layers (and quality) of stainless steel welds would put your average steel bridge to shame…
But fission will always be limited (as in non-renewable). If everything was powered by nuclear, I’m sure we’d see even more awefull mining operations. Also, fusion should in theory be much better, if the thermodynamics of it end up working.

Very on-topic SMBC today: www.smbc-comics.com/comic/mary
There are multiple types of color blindness, most of the time they affect the production of a specific cone inthe eye. Deuteranomaly is the red-detection cone being affected, and causes issues distinguishing red/green colors, but also blue/purple. It’s a “hardware” issue caused by less or lack of detection.
I’ve heard of “software” version of colorblindness, but it doesn’t seem to be as documented as others. I have a younger sibling that seemed to have “copied” my deuteranomaly despite being able to pass the “hardware” tests…
The exact neurons in the eye and the brain being triggeres are the same for detection of color, but where the “qualia” differs is to which external interpretation they are linked to. If we were able to isolate the souvenirs/associations that come from specific colors, I’m sure in general people would see the same colors.
Just like touching something hot triggers the same neurons as touching capsaicin, it creates a signal to the brain. What happens inside the brain depends on the life experience of each, but the initial signal is the same, and it can be proven with fMRI.
Off course, if we want to define a “qualia” as “the thing that can’t be proven by science”, then off course it won’t be provable using science. What is it, though?
- Comment on "Trippy" Reality 1 month ago:
If they’re fully color blind, how could they be shown colors? That would be a bad control group.
Instead, when doing fMRI stuff, they usually create a “baseline” by showing their subjects random stuff to see how the brain fires up. For example, they could show greyscale images of grass, sun, blood, etc., then see how it differs from seeing contextless colors (ie: a uniform green screen)
- Comment on "Trippy" Reality 1 month ago:
They did researchers with fMRI that showed that the same colors activated brains of viewers the same way, giving as much weight as possible to the idea that people perceive colors the same way.

The whole point was to get people sitting at the same table to reduce risks of conflicts… Without veto power, some countries would never have joined, which is unfortunate.

My understanding was that it was a risky moment, they didn’t want to risk showing astronautes dying… But that doesn’t make sense since the same logic applies to most of the launch!

Former astronomer here! You can download a lot of data from open access websites such as data.nasa.gov or any of the big digital surveys.
I don’t know about today’s data format, but it used to be all on the FITS format, with lots of libraries in Python/Matlab/etc., and also the excellent SAOImage DS9, all available for free.
Here are some links: sites.google.com/cfa.harvard.edu/…/download en.wikipedia.org/wiki/FITS www.stsci.edu/…/our-collections www.sdss.org/dr19/data_access/

No matter how bad the writing was, this is not a good thesis supervisor! It’s funny to read the sassy reply, but I’d hate this professor…
Even doctoral students are still students and are there to learn.
A better review would have been something like “There are severe issues with the structure of the text” and then refer to an external resource on technical writing…

It probably produce/absorb heat somehow when being deformed. Then, we use it to boil water, turn a turbine, and generate power!

- Comment on Just answer the question you fuckin' nerd 7 months ago:
Haha that’s exactly it: perception of reality. It doesn’t change the underlying real world, and so it only affects “truth” if we are forced to redefine it based on what socio-constructivism wants it to be.
It’s just like alt-right debates: just by accepting to play the game, you already lost. It’s a logical paradox, and therefore it can’t be a valid theory.
- Comment on Just answer the question you fuckin' nerd 7 months ago:
Definitely not! It just so happened that in my life experience, I was introduced to socio-constructivism just at the same time that alt-right was beginning to be a thing…
When professors were telling us “Einstein proved that Newton was wrong” without understanding that relativity reduces to Newtonian mechanics at low speed… It really failed to get me on board.
