Found one more, which seems more advanced : https://syde.cc/

I had the same idea, but looks like someone beat me and did a better job overall. Tested it once and the simulations look good.

Liked the 'Written by human not by AI' bagde

The correct url is : https://www.quotationgenie.online. Not sure why the OP is not updating his posts with the correct links!!

Check this : https://pmc.ncbi.nlm.nih.gov/articles/PMC4252862/ This is a flouride alternative and seems to help teeth recover faster.

I assume its part of the system design course on https://bytebytego.com/.

There is a nice countdown page for it : https://jwst.nasa.gov/content/webbLaunch/countdown.html

Thanks for sharing. In general, what is the optimum number of links that are needed to understand a topic? I find anything with more than 10 links about the topic a bit overwhelming. Can we have a distilled list of such lists?

Personally, I feel that reading a couple articles written by a SME on the tropic informs one of where they stand in terms of understanding and what to read next.

What is going to protect this from all those meteoroids,asteroids and cosmic rays?

For this approach I don't know. It's a wire mesh so I think it can resist some damage.

I read about other approaches that make me marvel at mankind's genius. For instance, on the moon you could slowly spin a pool of liquid Mercury to obtain a radio telescope that is basically immune from microimpacts. Not sure how it would work once the mercury freezes solid due to lack of sunlight, but I think it's such a beautiful (but maybe impractical) idea :).

You can do that on earth, too. See https://en.wikipedia.org/wiki/NASA_Orbital_Debris_Observator..., https://en.wikipedia.org/wiki/Large_Zenith_Telescope for (decommissioned) examples (both found via https://en.wikipedia.org/wiki/Liquid-mirror_telescope)

The idea apparently came from Isaac Newton.

> Not sure how it would work once the mercury freezes solid due to lack of sunlight, but I think it's such a beautiful (but maybe impractical) idea :).

Can't you heat it through induction heating? Vacuum is good isolation, so it won't lose heat too fast. Keeping whole pool above -30 °C probably won't require too much energy.

Maybe. I honestly don't know and just read about it quite a while ago and can't remember the details.

But mercury is a heavy metal. It must be prohibitively expensive to transfer the amount needed to the moon from earth.

Agreed, that's why I wrote maybe impractical. I just find it fascinating :)

Statistics :) The chance of a wire is hit by something is probably extremely low. Electronics working in space is also an understood problem so I don't think it's an issue.

Probably the proposed wire-mesh design, it won't be a solid reflecting surface. Total exposed surface would be comparable to orbit telescopes.

Cosmic rays are a solved problem. at most you will run out of backup computers. asteroids, you just hope you'll not win the cosmic lottery of collisions.

Like we do on earth with the big ones.

But since there is no atmosphere stopping the small ones on the moon, who also can do damage: this likely will be a problem, because there are a lot of them over time.

So a laser shield might sound science fiction, but will maybe be necessary, for longtime operation?

Or is it possible to build some protective sphere, that does not hinder transmission too much?

I downloaded it and installed it, but could not try as it requires a signup with email!

1. The feature set on paper is impressive, but there should be a way of trying out the limited features in offline mode, without requiring a mandatory sign-up. So consider adding a demo mode both in the downloaded and web version.

2. Is there a way to host data locally?

3. The Privacy policy & Terms of service take forever to load. The loading times need some serious tweaking.

1. Originally, there was the function for trying it out without sign-up, but that function was removed. Our marketers didn't want that feature. I'm sorry.

2. It can't be. But you can use the app offline or by exporting & importing local data.

3. I'm sorry. I have nothing else to say but to reload. It's fine on our side.

Well, throw me in the bucket of people who've been lost by that decision. Sounds potentially interesting, but I'm by no means invested enough already to go through the whole account creation thing just to try it.

After reading your comments, Our marketers just decided to add the function to use the app as a guest again. So now you can use the app without signing up. Isn't it good?

How? I see nothing on the frontpage about that, when I click on Web Version there is only login options?

Sorry, it works now

I feel there should be some demo contant to showcase the learning process. I tried the guest account, but didn't see some demo content to import or try out with and didn't really want to spend the time to manually add content to test the learning process.

Having some demo content would help me quickly decide if this could be a good tool for me.

It is good, thanks!
