How to: Scientific Presentation

I… prefer doing oral presentation more than doing a poster one. Other than it seems like a bigger prestige, printing and hauling posters especially in international flight is such a pain.

As an Indonesian, I was really not grateful (hmm, maybe not me) enough that I am able to be a viewer of the whole, both sides of the sky, able to see both Crux and Ursa Mayor, sure truly a blessing, for the whole year.

Most of these (okay, maybe no Polaris for me) (

National/ International Astronomy Olympiad Problem Sheets

[Updated: 16 September 2020]

I have some of the files, but I think it’d be easier to link to their pages as well (so that if anyone asks me I can just link him/ her this). Basically, you can just go to their own respective websites, but having them in one place helps a lot (especially for my Indonesian students/ friends). I try to link to official websites if I can. If I don’t have the links but I have the files, will upload them.

Specks of Indonesia in the Solar System

(This is a part of Martian Series (Planet series?) I’m queueing in this moment)

Looking through this map which I have previously mentioned in this article, a crater’s name lit up my interest. Tomini Crater? Is that the same Tomini with the Tomini I know? After shifting through Martian Crater name list, I found 4 of craters with Indonesia-related names. Apparently this has been caught interest of other Indonesian article writers as proven by these articles. Are there other features in out solar system with names based on Indonesian culture and mythology? Apparently they are. Shifting through IAU Gazetteer of Planetary Nomenclature, there are few familiar an unfamiliar names with “Indonesian” in their description.
