So, @Line_112 , are you just going to ignore the many redshift measurements of GRBs that have been made? These measurements firmly place them at cosmological distances. https://www.frontiersin.org/journals/astronomy-and-space-sciences/articles/10.3389/fspas.2023.1124317/full

Why do you think this? It is an equal area projection. So dots of the same area will cover the same area of the sphere.

Here is an equal area projection map of the Earth, similar to the GRB map. Areas are not distorted, but of course shapes are. It's not possible to map a spherical globe on to a flat sheet of paper without distorting something. But these equal area projections have the advantage that area is...

What's your point? It's well known that gamma ray bursts are extra-galactic. Look at the Wikipedia page, which says, "In gamma-ray astronomy, gamma-ray bursts (GRBs) are extremely energetic events occurring in distant galaxies which represent the brightest and most powerful class of...

What is done here is to release a huge number of sterile male flies. The females then mate with the sterile males and lay unfertilized eggs, which don't hatch. Eventually the screwworm files are all wiped out, at least in a region. What did you want to use this technique on, besides "mere...

We're building a new factory in Texas with the capability to produce 300 million sterile male screwworm flies per week. This is how we eradicated this pest before, and it should work again...

I strongly agree with the importance of unit tests. But there is more to it than that. I have had cases where the code writer said, "It passed the test suite, so it's good," and never tested the code on the actual application. It's important to run unit tests AND test the code as it is...

Yes. Typically you will not be charging a capacitor with a constant current.

I've found that when I'm documenting my code, one of the main people I'm writing the documentation for is me. So that when I come back years later and ask myself, "What the hell was I doing?" I get some sort of answer.

My experience has been that the algorithm is usually not the main question when looking at code. I'm agreeing with @Filip Larsen that the pseudocode is really no clearer than the actual code. I think the most important things to document are: (1) What are the inputs and what datatype are they...

My wife is planning a hip replacement surgery. Before the surgery, they tested her skin for MRSA. They said if she has it, they will modify the post-surgical antibiotic campaign to deal with it. So, as others have said above, it seems that there are still antibiotics that can stop it (for now).

Also, how large is the receiver?

My experience is similar. Growing up in the US midwest, I got many, many mosquito bites. Then I spent time camping in Wisconsin and Minnesota, where they are everywhere. Now, 40-50 years later, I still get bitten, but no welts.

I think a key part of understanding the Riemann hypothesis is understanding why the Euler formula is true. Wikipedia has an excellent page with some nice graphics showing why this is true.

The book "Prime Obsession" by John Derbyshire I think will answer your questions at the level you want. It will take some time to read, but is worth the effort. Here's a link on Amazon, but you can find it elsewhere.
