Science Bulletins: Saturn System Is Showing Its Age

A new study uses thousands of infrared photographs of the Saturn system to reveal that the planet’s moons and rings are older than expected. A surface dusting of dark minerals helped conceal their age, but distributed underneath is an abundance of water ice—a telltale leftover from the earliest days of the Solar System, billions of years ago.

“They presume that, if the math is not coming easy, that therefore you’ll never learn it, and I meant it literally that math is the language of the universe and it’s like any other language, especially a language that does not share the Roman alphabet. So, for example, if you wanted to study chinese it looks completely intractable, at first.

And so, and you could ask the question, “How long does it take one to become fluent in Chinese if you are not Chinese, yourself?”

And so, it can take years and five years, almost 10 years if you never go to China. You go to China for maybe five years of intensive exposure and you’ve never done that with math. Imagine that level of exposure to math. What kind of fluency you will have at the other end of that pipeline?

So, at least give yourself the opportunity that any person learning a foreign language would give themselves, before you turn around and say you’re not good at math.”

— Neil deGrasse Tyson

people always assume that i’m extremely good at math because i genuinely enjoy it, and that’s just not always true. math has been a struggle for me my entire academic career, but it’s something i love. i may have to work a little harder and study a little longer to understand things, but it’s worth it to me. if you can understand math, you can understand the universe, and that’s worth the difficulty.


Backing Up From Earth

I look up — many people feel small because they’re small and the Universe is big — but I feel big, because my atoms came from those stars. There’s a level of connectivity.

That’s really what you want in life, you want to feel connected, you want to feel relevant, you want to feel like a participant in the goings on of activities and events around you.

That’s precisely what we are, just by being alive…
