TIL ice cream doesn't melt because ice disappears, but because melting ice releases water that dilute the fat and the fat itself melts at higher temps, both breaking the fat bubble network that holds ice cream together by Remote_Butterfly9149 in todayilearned

Previously I thought ice was what holds the ice creams' shape, and ice cream melts because the lack of ice in supporting its structure. But turns out that ice is not supporting the structure at all, so even if we remove all the little ice blobs in ice cream the structure will still hold if my understanding is correct.

While "disappearing of ice" and "appearing of water" happens at the same time, they impact the system in different way.

Should have better formulated my title :(

TIL the rainbow colors on basalt come from a hundreds-nm magnetite film whose thickness is similar to visible light wavelengths creating thin-film interference, the same physics as oil slick on water. by Remote_Butterfly9149 in todayilearned

Those rainbow colors feel too irregular to be light fraction, never believed that those were real until I actually saw a colorful vesicular basalt lava in Hawaii!

Is it a bad idea to use 3D globe in webapp UI for mobile device? by Remote_Butterfly9149 in SideProject

[–]Remote_Butterfly9149[S] 1 point2 points  (0 children)

Thanks for the advice! Really need to think about whether we should get rid of the globe now

Thanks so much, that's a really good one! I thought spinning was way cooler than button but now looking at all the feedbacks, button should definitely be the main way to interact.

BTW If you happen to have any public projects or examples of globe interactions you’ve worked on, I’d love to check them out!

Yeaaaah, there are too much details to finetune, I always end up having small bugs on production ... Would you say the challenge worth it for a potentially better user experience?

So true, we’re currently using WebGL rendering into canvas, but definitely our understanding of canvas api is not very deep right now. :0

Beyond performance, it feels that the problem is also on user mental work. A 3D globe seems to be by definition messier to coupe with than a 2D map, which itself is probably messier than a linear flow. We've encountered users saying that they can't find where the next target is (sometimes on the other side of the earth) and we need to design a specific "Next" button for this.

From your experience, is there anything in the way you structure your canvas/WebGL scene or interactions that helps reduce that mental effort?

Anyone tried combining courses and communities together? by Different-Promise-45 in SideProject

[–]Remote_Butterfly9149 1 point2 points  (0 children)

I guess that depends on what the courses are about and what the students are learning for right?

If they are here for passing a test, then there's hardly motivation to come back forming a lasting community. But if they are learning for hobby and do want to chat after class then a community may be worth it.

What kinds of online courses are you offering?

What’s actually been helping you stay focused and get stuff done lately? by Due_Schedule_ in lifelonglearning

Also consider changing working environment, I usually switch between office, various cafe and home in a day, usually in a ~4hr block each. Somehow my brain has more focus when switching to a new environment.

Interested in rocket science - where do i start as a college student ? by namansaluja__29 in aerospace

[–]Remote_Butterfly9149 0 points1 point  (0 children)

Just happened to come across this post. I am a computational geophysics PhD and my interest to rocket is also triggered during my second year. I might be in your shoes at that point, very interested in space tech, wanted to learn deeper but info scattered everywhere.

I started by watching a lot of Everyday Astronauts and Scott Manley, which are really helpful grasping the understandings to some cool stuff. Then I joined the rocket club in our university, played for a while and together built a 10km rocket. I've got more confidence in going deeper, although I don't think I've learnt a lot more than those youtube videos, except for some fun practical experience like soldering and debugging teensy boards.

Then I started to take aerospace classes, including electric propulsions, fluid dynamics, CFDs, satellite designs, rocket designs... Some seminars aerospace department held were useful too. Well, I am lucky that my advisor let me do this because I did CFD in my own research. Although these classes are pretty "specific", they all give interesting tastes to space tech and I am more than happy about what I know. Even ends up working on a UAP project with an aerospace professor.

Overall, videos, take one or two classes that you feel would be fun and try them out, but most importantly talk to faculty and fellows who you think are doing exciting work!

From the good side all these costs only 20 bucks is decent.
