people reading this article are engineers, technicians, academics, and hobbyists who appreciate the sciences
and how they categorize, define, and explain the world around us. I think it not inappropriate, then, to
present on occasion a few 'factoid' type pieces on topics not directly related to RF and microwave
engineering. Many, if not most, nay, if not all modern discoveries are aided in part or in whole by
the advent of electronics - even if that bit of electronics is a computer that crunches numbers for analysis,
simulation or processing words in a technical paper. Accordingly, you will probably appreciate these few short
tidbits of astronomical information which überprolithic astronomy author and practitioner
Bob Berman wrote for the 2015 edition of
The Old Farmer's Almanac (aka
Mr. Berman, with his story-telling, one-on-one conversational style of prose has long been one of my
favorite authors in the monthly
Astronomy magazine. He has a unique way of presenting astronomy subjects in familiar terms while
still including relevant technical data. These interesting factoids are included in a larger list in the OFA
- The longest star name still in common usage is 'Zubeneschamali.'
The shortest is 'Sun.'
- The sun's energy output is equivalent to the explosion of 91 billion, 1 megaton hydrogen bombs each
- Mar's moon Phobos will crash
into Mars' surface in 10 million years. He didn't say how long until its other moon,
Deimos, will suffer the same fate.
- The first person who said Earth moves through the heavens was Aristarchus of Samos, not
Copernicus or Galileo.
- The most abundant type of massive (although miniscule) object in the
universe is the neutrino. A trillion
neutrinos pass through your fingernail each second.
- While the number of stars seen in a truly dark sky seems, well, astronomical, in actuality, given the
average person's ability to see stars down to around
magnitude 5.8 (naked eye),
the most any observer can see at one time is about 2,600. You could count them all in 20 minutes at the rate
of two each second.
- In addition to white, stars are also colored red, blue, violet, yellow, brown, even black. The single
missing hue is
(see, though, 'Zubeneschamali').
- The universe's second most abundant element, helium, is the only one that never freezes solid.
