Replying to a redditor:

> Dr. Tyson, What advice would you share to an undergraduate of physics and mathematics who is very uncertain about a future career in science? Some nights feel defeating from the course work alone, but the thought of a future career based on my education can be overwhelmingly…

> I may be partly guilty for your scientific angst.  Most of my public science persona involves conveying the joy of scientific discovery, and especially the joy of curiosity, from childhood through adulthood.  What's commonly absent from my messaging is the steep investment of time and energy (physical and emotional) that becoming a scientist and actually doing science requires.  In fact the struggle **is** what must be loved by aspiring scientists because being a practicing scientist requires this of you daily.
>
> Not knowing the answer to a problem and struggling to find the answer is precisely what science is.  It's neither more nor less than this.  The fact that you are experiencing this very struggle is not a barrier to your progress it is the best evidence that you are on a path where you belong, if you love what you do.

> Good luck.  Sometimes you need that too.

Replying to a redditor:

> What's something you've learned recently that's really blown your mind?

> Lately I've had about one such incident per week. Although my target is one per day.  I recently learned from some dynamicist colleagues that the striking visibility of Saturn's ring system is not eternal, coming and going with the dynamical forces of all that orbits the planet.  Which means if I were around back when the Dinosaurs roamed and showed them Saturn through a telescope, it might have been an uninteresting sight.  Very sad.  -NDTyson

Replying to the post "Chicago Theater at 2:30 am.".

> Indeed, the Chicago Theater photographs beautifully -- especially in an era with fewer and fewer marquees.
>
> And agreed, there's always something surreal about a quiet City scene that is normally abustle with people.  This photo might have been early morning October 18, 2018.  And what they don't tell you is that **during** your show they change the marquee to the next day's performer. So when you exit, you're simply yesterday's news.
