San Francisco “Cool”

May 15, 2014

Bay Area Regains “Cool” After May Heat Wave

A familiar sight returned to San Francisco. Fog:

Fog found its way over the Golden Gate Bridge.

Before bumping into warmer air.

Southern California, however, continued to bake and burn.

Multiple smoke plumes from San Diego Co. fires were visible on radar:

Some 16,000 new evacuations orders were issued today.

Southern California is baking in early May heat.

And burning.

San Francisco enjoyed cool relief.

Its heat wave broken.

But cool remains elusive for thousands impacted by fires to the south.

SoCal’s heat wave may not break until the weekend.

PI Day 3/14

March 14, 2014

Pi is one of Nature’s most mysterious and fascinating constants

Pi is everywhere.

It’s in equations of planetary orbits, the color of the Northern Lights, even the structure of DNA.

Per Wikipedia:

“The number π is a mathematical constant, the ratio of a circle’s circumference to its diameter, approximately equal to 3.14159. It has been represented by the Greek letter ‘π’ since the mid-18th century though it is also sometimes spelled out as ‘pi’ (/paɪ/).”

Pi fascinates humans, and has for a long, long time.

Artists celebrate it, too:

Pi Day
Michael Albert, artist, NewYork: 

Pi also frustrates us.

For example, it’s an irrational number.

We are unable to explain it as an exact, common fraction.

Darn thing never ends in decimal form – which is infinitely long.

And it never evolves into a permanent, repeating pattern.

Supercomputers calculate Pi out to billions and billions of digits.

“And they’re still going.” No end in sight.

One school kid memorized Pi to 10,980 digits:


The bottom line?

Although the value of Pi is just more than three, it’s flat-out fascinating.

Into math – (or geometry, cosmology, fractals, electromagnetism, statistics) – you’ve already fallen deeply into Pi.

Not only that. Pi is “Phun.”

You can compute Pi by dropping needles.

Or with frozen hot dogs.


Try the hot dog test.

Fry and eat them later.

Pi is so cool, it even has its own day.


March 14. As in, 3.14.

The difference?

This day will end.

Pi keeps on giving.

But why?

That’s a mystery.

Big, Red Sprites

Cooler Than Elon Musk?

Well, perhaps not:

Sprites, “squirting up.” See them?

Start of a night of wonder:

Noctilucent Cloud Outbreak

May 31, 2013

Luminous Electric-Blue “Night-Shining” Tendrils

Per SpaceWeather:

Noctilucent clouds form near the top of Earth’s polar atmosphere when water vapor from the planet below mixes with meteor debris from space. They appear during summer because that is when the mesosphere is coldest and most humid. This year, they appeared early, more than a full month before the solstice, setting the stage for an unusually good NLC-watching season.

High-latitude watchers should be alert for repeat shows.

Colorado, too.

Look west 30-to-60 minutes after sunset.

And if you see blue-white tendrils?

Weather-science cool.
