Re: The Larger Picture
My dance teacher friend (our relationship is mainly that I assisted her for about 14 years) has an iPhone. As a retired software engineer, Apple software just drives me crazy in how it keeps me from performing the most basic programmer tasks. Even the "Genius Bar" geniuses have told me that the most basic functionality that I need, being able to transfer individual files between my phone and computer (ie, PDFs or photos), was impossible with an iPhone. In addition, photos and videos of my grandsons (all the way across the country in Florida) are unnessecerily complicated because of incompatibilites between Apple and non-Apple devices. A classic example was when I had an AVI file from my camera of a dance routine we had done the week before and tried to display it for the class on a brand-new Mac. That brand-new Mac could not recognize that decade-old AVI file. "Not manufactured here." Well fuck you very much, Apple!

In our two European trips, my friend and I traded our photos afterwards. This second and last time (she died last year on Veterans' Day) she couldn't share her photos because her new iPhone had a proprietary photo format that was incompatible with everybody else. Well fuck you very much, Apple!

My dance teacher friend keeps castigating me for not switching to Apple, but who would ever want to drink that Kool-Aid?

a bite off the Apple
Fortunately the Budgie desktop can be made to look like an Apple desktop but you can still actually do stuff.

I've been known to build computers for some kids that can't afford them and they seem to like the Apple look so often I install the Ubuntu Budgie desktop. It has tools that will even handle most of the Appleized formats but that are also real world compatible.

Re: a bite off the Apple
Apple was smart in their marketing, but it screwed a lot of kids up.

Apple donated a lot of Apple computers to schools. Generations of kids and teachers grew up with Apple computers. Every time we see anyone on TV using a computer, it's most likely an Apple computer or iPhone (in European productions, I saw a lot more Windows computer and phones in use). Then those kids went out into the real world economy and had to work with Windows computers because that's the route that business had taken.

So just who the frak would ever want to make their device appear to be a fracking severely impaired Apple device?

How do you edit a text file? How do you do a hex dump of a file? How do you do anything at all meaningful on an Apple device? You can't even right-click on a screen object. Absolutely useless!

I had a TNG tricorder app on my Palm Pilot. One of its built-in scanner settings was for heating up a microwave burrito. Unfortunately, my Palm Pilot didn't have the required hardware upgrades so I was never able to properly test that feature.

For my coffee, I stay old-school and still use my Bialetti Moka Express.

Clever Studies in Astrophysics
Today there were several articles in my SciTechDaily news feed about clever, innovative astronomical studies to refine the measurements of the expansion rate of the Universe, plus, is it uniform in every direction? And using gravity waves, specifically created by merging neutron stars, to tell us about all about these stars including the orientation of of the rotating pair.

Gravitational-Wave Scientists Brilliant New Method to Refine the Hubble Constant – The Expansion and Age of the Universe

quote:
A team of international scientists, led by the Galician Institute of High Energy Physics (IGFAE) and the ARC Centre of Excellence for Gravitational Wave Discovery (OzGrav), has proposed a simple and novel method to bring the accuracy of the Hubble constant measurements down to 2%, using a single observation of a pair of merging neutron stars.

I think this was a pretty good article about this study with a lot of good background into the questions we are trying to ask about dark energy that might clues to which questions might increase our understanding of what is observable and how to do that.

Dark Energy Experiment 16 Years in the Making Could Illuminate Origin, Evolution, Fate of Universe

quote:
A map of stars and sound
“HETDEX is very ambitious,” Ciardullo said. “It’s going to observe a million galaxies to map out the structure of the universe going over two-thirds of the way back to the beginning of time. We’re the only ones going out that far to see the dark energy component of the universe and how it’s evolving.”

Both these articles are fairly well written. Occasional articles in their list I would say the best part was the title. Some had whole paragraphs repeated in the same article, but every day I find good articles about studies and findings in the branches of science and technology that interest me. One thing I like about SciTechDaily is a nice list of references for every article.

It's interesting reading while my imaging computer is processing thousands of images every day.

A question just occurred to me, Do gravity waves have an effect like the electromagnetic red-shift from cosmic expansion?

Another question, why is the speed of gravity the speed of light? Is it coincidence or is there an obvious link between gravity and light that I am overlooking?

Re: Clever Studies in Astrophysics

Apparently, yes. Not to be confused with "gravitational redshift" where a photon expends energy to leave the gravity well.

https://arxiv.org/pdf/1312.1862v2.pdf

Is it coincidence or is there an obvious link between gravity and light that I am overlooking?

The tie in to Maxwell from Special Relativity shows the "speed of causality" in the equations. GR gives the same constraints on gravity wave propagation as does Maxwell show for EM.

Thanks, good answers!

I'm anticipating the development of the field of gravitational wave astronomy that will open new views of the Universe the same ways that light, radio, X-ray, and Gamma-ray astronomy have. I can imagine the gravity data being used to create visible images of the Universe similar to the images created using various parts of the electromagnetic spectrum. I am disappointed that I will not live long enough to see it developed into a mature branch of astronomy.

Features of Science
One of the positive features of science, that is often unrealized by non-scientists, is the tradition and responsibility to train the next generations of aspiring scientists. This is not just giving students a sampling of the accumulated knowledge previously acquired by scientists in a specific field, but how to engage in science and apply the scientific method to understand observations.
