The same argument can be made against the Muslims who think that their religion applies to people outside of it. I am not Muslim, so I am not going to hell for displaying a mockery of their prophet. After all, would the Muslims want to be held accountable to the rules of every other religion in the world?

This is the real problem, and it's on all religious people to behave as if every other religion (and every form of non-belief) is as valid as theirs is. Oh, and Thou Shalt Not Kill.

Drug-store reading glasses only work if you have nothing but identical far-sightedness or near-sightedness in both eyes.

I am over 50 and have always had astigmatism, and deal with the lingering and ever-changing effects of a shingles scar on one cornea, so my glasses are anything by simple.

My computer glasses solution is to have one pair of trifocals for general use, and a pair of bifocals ground to give a general view of the computer screen, with a close-up along the bottom for looking at the gizmos I'm designing circuit boards for when I'm on the computer. It works pretty well, other than the inconvenience of having to change glasses a lot.

The PLA that I use in my old Ultimaker is melted in the printer at 220C, but it becomes soft and deforms at the much lower 60C that we typically get in our cars in Tucson in the summer. I had to print a second set of propeller blades for my nephew's underwater robot after he left it in his car one day!

I have one at home that I use for doing iterative prototypes of product designs, among other things. When the turnaround time for improving a design is an hour, it's possible to make a lot of refinements.

I work on the engineering side, rather than the project management side. The two EHT telescopes that I work on are in Arizona, although I build some of the hardware that's being taken to the South Pole Telescope. It's getting improved to be a part of the EHT. One of the Arizona telescopes is a prototpye ALMA antenna that we just moved here from New Mexico last year, and got working a month ago.

Observations are typically done in March/April. This gives good weather at the many sites involved. The typical run is a week, and they try to get several 10-minute recordings during that time period. The data is recorded at 1 Gbyte/sec onto banks of hard drives, then shipped by FedEx to MIT for correlation. (I don't know if a FedEx truck makes it to the South Pole every day.)

The frequency used for most observations in in the 1.3mm band. The baselines are intercontinental (Arizona, Hawaii, Chile, hopefully Antarctica), up to 5000 miles. The goal is to actually get fringes between all stations, although that's not always possible due to weather and/or equipment acting up.

I work in radio astronomy. From what I can gather, things in other star systems are too far away to even be able to communicate, much less transport between them.

Those huge arrays of radio telescopes being built in Chile and South Africa are able to detect things on the order of a planet in size. That doesn't mean that they can communicate with the planet, just see that it exists.
