Best Local Stargazing and Dark Sky Sites

Nothing says applied mathematics like physics, and nothing says physics stars and cosmology.

Following is a list of best places in the SF Bay Area and around California to find dark, clear skies ideal for star gazing.

A good pair of 7x50mm binoculars makes stargazing even more amazing. Click here for a great deal on an excellent set for beginners.

Factfulness

Despite rumors to the contrary, things aren't so bad. They're probably quite a bit better than you think. That's the thesis of this book by Swedish author and public health expert Hans Rosling.

From the book's description on amazon:

"It turns out that the world, for all its imperfections, is in a much better state than we might think. That doesn’t mean there aren’t real concerns. But when we worry about everything all the time instead of embracing a worldview based on facts, we can lose our ability to focus on the things that threaten us most.

"Inspiring and revelatory, filled with lively anecdotes and moving stories, Factfulness is an urgent and essential book that will change the way you see the world and empower you to respond to the crises and opportunities of the future."

Here's what Bill Gates had to say about Factfulness:

“One of the most important books I’ve ever read―an indispensable guide to thinking clearly about the world.”

And Barack Obama:

"Factfulness by Hans Rosling, an outstanding international public health expert, is a hopeful book about the potential for human progress when we work off facts rather than our inherent biases."

Rosling isn't a Pollyanna who refuses to acknowledge the very real problems and challenges humanity still faces. His point is that, if we actually follow the facts – instead of persistent, unconscious biases – there's much more reason to be proud and hopeful than we might ordinarily believe.

I enjoyed Factfulness, and highly recommend it to all with an interest in the state of the world.

Wolfram Alpha

Stephen Wolfram and his engineers, makers of Mathematica, are at it again.

Wolfram Alpha is Stephen Wolfram's groundbreaking computational knowledge engine, one of the earliest such applications online. 

Type a question into the calculation field, and Wolfram will input the question and output the answer on-screen.: "How many goats in Japan in 1986?" Alpha knows the answer (~47,500).

Input z=x^2+y^2, and Alpha will output a 3-D graph along with detailed information about the relation.

Also of interest is Wolfram Mathematical Functions, the largest repository of mathematical functions ever to exist. 

Math fans, especially, will find Wolfram Alpha a fun site to peruse.

Math and the Master

The phrase "Renaissance Man" is epitomoized by Leonardo da Vinci, the master of masters, founder of the High Renaissance. Geometry infused Leonardo's work, and was a particular obsession of his (e.g. The Golden Ratio, perspective, knots, fractals).

An article published by The Mona Lisa Foundation goes into some detail about the geometric underpinnings of Leonardo's design thinking.

It begins:

The important relationship of mathematics to art cannot be [overstated] when discussing Leonardo’s later work, and in numerous documents, letters and notes, the relevance of this is well documented. At times, he seems obsessed with these issues: while working on Mona Lisa for example, Leonardo is reported by Fra’ da Novellara to be concentrating intensely on geometry.

“Non mi legga chi non e matematico.”

“Let no one read me who is not a mathematician.”

-- Leonardo da Vinci

Cosmic Eye

This epic science video takes viewers from the realm of everyday human experience to macrocosm, microcosm, and back, by the power and magic of exponential growth. 

It's a brief 2:29 excursion that could make your day.

Powers of 10 was one of the first such "logarithmic zooming" films, released in 1977 by ground breaking mid-century designers Charles and Ray Eames (see Wiki article here). Orders of Magnitude is an excellent recent variation on the same theme.

Guidebooks: Science Experiments and Projects

Scientific inquiry, invention, experimentation, and discovery are all possible at quite sophisticated levels using ordinary materials found in every home or easily purchased online.

Parents without scientific degrees, however, will normally draw a blank stare at the thought of setting up and operating a "family lab" at home.

Fretting is unnecessary, however. By setting aside a dedicated science space in the home (even just a small table and bookcase in the family room), and using a few good books as guides, the task needn't be unduly burdensome.

To get things going, below are listed some great activity books for young scientists and their parents:

STEAM Kids

Exploralab

Exploratopia

The Science Explorer

The Curious Kid's Science Book

Big Science for Little People

The 101 Coolest Simple Science Experiments

The Big Book of Makerspace Projects

Tinkerlab: A Hands-On Guide for Little Inventors

Electronics for Kids: Play with Simple Circuits and Experiment with Electricity!

Family Science

As essential academic skills, the "3 R's" (Reading, Writing, 'Rithmetic) dominate primary and secondary education at nearly every phase. This is as it should be.

However, a close second place should be assigned to STEAM subjects: Science, Technology, Engineering, Art, Mathematics.

Family science study can be a rewarding and fascinating family activity. Investing a relatively small amount of money in a scientific instruments of reasonable quality can open up entirely new worlds to impressionable and curious young minds. For example, keeping a good compound microscope at ready disposal in the family kitchen avails kids and adults alike of the opportunity to do real spur-of-the-moment science. Having a serious entry-level telescope standing by in the garage for use on those clear, dark, moonless nights when star gazing is most rewarding is a simple way to reify the infinite for youngsters and adults alike.

At all stages, the scientific method can be taught, utilized, and reinforced: Ask a good question, make a sensible guess about the answer, test that guess experimentally (or search the internet for information), confirm or adjust the guess based on what's learned, then repeat.

Having popular scientific magazines prominently displayed at home – and making sure your kids catch you reading and discussing them frequently – is another fun and engaging way to bring science into the home.

Why is it that so many scientists are amateur artists, musicians, painters, video programmers?

The arts are, of course, inextricably linked to the sciences. Affinity for one generally predicts affinity for the other. Music, dance, acting, visual arts, sculpture, architecture, and other diverse artistic disciplines intersect in fascinating ways with scientific fields ranging from physics and chemistry to anatomy and psychology.

Moreover, the dedication, sharply-focused thinking, and keen observational ability required to become a competent stage performer or fine artist are precisely the same "soft skills" central to advancement in STEM fields (but that's another post ...).

Parents can thoroughly enjoy home science along with their kids. The excitement of discovery is every bit as tangible and real when an adult first witnesses an oozing protozoa gobble up a bacterium as it is for a first grader or high schooler.

Full STEAM ahead!

Robotics Toys, Aids, Activities

50 years ago, robots were menacing, man-like machines with starring roles in sci-fi movies and television shows.

Today, robotic machines are having a real impact on the world economy and are beginning to enter our homes and daily lives.

50 years from now, robots will likely do most of what we call "work" today.

As artificially intelligent machines begin to enter our daily lives, it's now possible for kids of all ages to design, build, program, and control their own simple robots.

Following are a few ideas to help get you started:

Sphero SPRK+

Cubelets

Raspberry Pi

Raspberry Pi on amazon

Raspberry Pi Projects and Programming

Arduino

Arduino on amazon

Science Tools and Manipulatives



Like math manipulatives, science manipulatives enable students to learn and comprehend key early concepts viscerally through hands-on activities.

Basic scientific instruments extend the senses and allow further exploration and data collection.

The list below provides a starting point for parent-teachers interested in building a home science lab:
