Delightful and thought-provoking!

Absolutely delightful and thought-provoking Audio book, read by Tyson himself. (An excellent companion volume to Hegseth’s “Take me to Your Liter”. )

Quick read, entertaining & informative
Format: Hardcover
This book can be enjoyed on several levels. It could be tongue-in-cheek or satire, but is also backed by facts and conjecture by one of the world’s greatest scientific thinkers. I think Dr. Tyson had fun writing it, and i certainly had fun reading it. And I learned a lot.

Aliens: Know what to expect!
Format: Audiobook
This is a really fun review of Earth's obsession with alien life, what we have historically expected of aliens--and what they might expect of us.
If you are a long-time listener of the author or a viewer of his YouTube show (Star Talk), you have probably heard much of what NDT has to say on this subject already--here and there as he picks his way thru the universe, but why not listen to him now again as he focuses his energies on just this alien subject? If you want an enjoyable read, it will be worth your time. If you're not a long-time listener of NDT... and you have any interest in aliens at all, then you DEFINITELY should give this book a go. It is full of thoughtful insights from a man who has devoted his life to the science and 'cultural impact' of the stars.
I listened to the Audible version wherein NDT reads his own book aloud for you. His efforts really allow you to gain his insights... And his strong sense of humor--in equal doses.

My son is actually motivated to do a workbook
Format: Paperback
My Kindergartener finished homeschool online early and we have been doing a page a day and he loves it and loves to earn a sticker after each day and put it on his chart. I love how engaging the workbook is and how it introduces some 1st grade concepts. Would highly recommend.
