I think it’s possible to be too clever here. We don’t teach children to count
on their fingers starting with 0 -1-2-3 etc. Also, the concept of zero came
long after that whole numbers.

Seriously guys, this is the beginning of the decade called THE TELESCOPE

Engineers like Dr. Mozdzen and Mr. Kozel know that numbering starts at ZERO
in mathematics, engineering, and telescope making, and the beginning of all
time. This is the start of the next decade, the "TELESCOPE TWENTIES". Some
liberal arts folks like musicians insist at counting time starting at "one"
and ending at "and ah". Putting the downbeat at 'one' never made sense to
me. Musicians also screw up the numbering of harmonics, using the term
"first harmonic" to describe TWICE the fundamental frequency. I forgive them
for that and like to dabble in music myself.

Paul,
I must correct your statement that we are beginning a new decade. 2020 is the
tenth year of the current decade, not the start of a new one.
We begin our counting with the number One, not Zero, and each decade has ten
years, thus 2020 being the last year of the current decade.
2021 will be the beginning of the next decade. The same reasoning is used
with the new centuries. For example, the 1900's were the twentieth century
and we are now in the twenty first century.
I can't convince my wife of this no matter how hard I try, so I let her think
what she wants.

Hi,
We'll have this decade's first Amateur Telescope Making and Astro-imaging
meeting on Tuesday, Jan 7 in my shop, starting at 6:30. I plan to set up the
Foucault tester, so bring a mirror you want tested. We'll also do some
drilling and tapping on the lathe on a part that Lynn needs for his "double
telescope mount". So, if you have any small machining projects, bring them
over Tuesday evening.
