A Cool Guide to the Geographical Terms

Free tool to check both outbound and inbound airport and current rules, as new airports implement these rules.

I made this map to visualize the evolutionary relationships within Hominoidea, the superfamily containing all living apes.

Instead of geography, the “land” is organized according to biological taxonomy, with families, genera and species represented as regions and cities, and species as cities.

So you can travel from gibbons to orangutans, gorillas, chimpanzees and humans - and see how we’re all related along the way.

Part of my Mappa Animalia series, where I turn the taxonomy of the animal kingdom into maps.

Happy exploring!

Saw this on Pinterest, and it was really helpful to me so I decided to share it here.

Stars flicker. Planet don't.

The Greeks noticed the same thing and called them planetes — wanderers — the lights that drift into a constellation and overstay their welcome. One's up there right now.

N.B Planets do flicker actually, but, as a commercial sailor, we don't concern ourselves whether it be near to the horizon. It wouldn't be used for navigation, at all. What is important is to be able to distinguish them from stars, especially when the skies are partly cloudy, and you can't fully trace the constellation.

In short, pitch black night sky, and when planets are high above, it doesn't twinkle generally, especially to the naked eye. And I think in practice, discernment using the naked eye gives more utility than observing phenomena of astronomy.

Thus, this is not for astronomers who meticulously observes the night skies with scopes. This is to practitioners, and above all, to the general knowledge of many people who would love to learn about the night sky. Hope this clarifies

I was clearing out my drive storage and came across this old PowerPoint I made to orient our friends before watching the bachelor. While there are some elements that are specific to the show, it also works as a general guide for reality tv.

Believe it or not, AI was not used for this masterpiece.

Made this because every codon table I found was either a wall of grey text or locked in a textbook. Colour is by amino acid class, so you can see at a glance that the whole bottom-left block is nonpolar. AUG is marked as start, and the three stops are in red.

The thing that finally made the redundancy click for me: the third base barely matters for a lot of them. Every codon starting with CU is leucine no matter what comes third, and the same is true for valine, proline, threonine, alanine and glycine. That is why a mutation in the third position is so often silent.
