How far can you see? Making Telescopes
It wasn't that long ago, that the "Glass Giant of Palomar" - a huge 200 inch
that's a 16.6 foot diameter piece of pyrex glass about a foot or two thick. It's an
incredible story itself from casting the glass mirror at Corning, NY to grinding and
polishing it to protecting it in it's long railroad journey to North San Diego County,
California from crackpots that might take a shot at it, to the incredible technology of
it's mount. The whole story is in a book by David Oakes Woodbury - The Glass
Giant of Palomar - a great read.
I read this and many other books like it on telescopes, the history and making
of telescopes as I built my own six inch - that's a six inch diameter mirror -
reflecting "Newtonian" telescope. I ground it by hand! I still have a
photo of it. It cost me eleven dollars for parts, including the glass mirror blank and
glass "tool" - the disk you grind the mirror to be against.
The theory is that if you simply grind one surface against another you will be left
with either a totally flat surface, or spherical surface whose reflective focal length
depends on the length of the strokes you used to grind it. Only it's not so simple.
They've been doing these since before the discovery of glass, using metals
instead, that produced actually excellent results in viewing.

I'm not writing this piece for fun. Not at all. in fact, it's brutally difficult and I'll tell
you why. The purpose is to help me and others clarify something that has had me
very hard down for quite a while and very difficult to explain. I can recall working for
the Church of Scientology in the UK. We were at the American University, not the
large American University in London, but a smaller one and closer to East
Grinstead where our organization was based. We were trying to recruit students
and sell books by L. Ron Hubbard to the students there. If students from the
American University had come to St. Hill - the place where scientology was
located - in order to sell books - any books at all - or recruit students for their
courses - they would not have been allowed on the grounds.
The L. Ron Hubbard policy toward standard education was
that it was not only worthless, but down right close to evil. Anything not written by
L. Ron Hubbard was largely and usually worthless and down right close to evil.
This attitude would make many people defensive and probably somewhat
annoyed or offended since they'd spent much time in schools where they'd
learned to read and write and add numbers and learn about many important
subjects.
Hubbard attended George Washington University for two years, had poor
grades and dropped out. He majored in Civil Engineering and told Look magazine
"He never took his degree".
For the record, engineering school is hard work, very hard work. Landing a man
on the Moon is no little thing, and neither is building a bridge.
What got to me at that school was that after having adopted Hubbard's attitude
about the worthlessness of higher education, and despite my own real experience
in excellent schools, I found myself in their gym shooting baskets and had very
mixed emotions that day about the experience. Something was wrong. Something
was gnawing at me. Sure, people should not be judged totally by their grades in
public school or any school for that matter. There are many other important things
in life. Additionally, many students who haven't the resources, can't afford school or
are pressed into working early instead for economic reasons. Still, most schools
usually do an excellent job of helping students live better, more useful lives no
matter their circumstances and, in fact, are there first to help any student have a
complete and practical education. To say less and to ignore the good schools do is
far from what you what expect from the "humanitarian" that Hubbard continually
claimed he was. He's gone now. May he rest in peace. My purpose here is not to
find things that are wrong about others in my estimation, but to point out the best I
can the true and most important contributors to today's current and most
successful technologies, whatever area of life they might be concerned with.
I felt bad at that gym because I had stopped supporting standard education and
instead was supporting those who considered it a waste of time at best. And, here
it had done so much good for myself and my friends.
Look, it is probably true that Hitler's camps for Germany's youth had many fond
moments for the young boys and girls that attended. That's not the point at all. The
point is that there is practically no hard sell to public school or most private
universities either, yet the human and social value is extremely high. The same
thing can be said about good family. The parents do everything they can to help
their children. In the same way, schools are among the finest things a community
has to help its children. Technologies are developed to help people, to make their
lives easier, their work more efficient. The best, the true sources that help man, do
not make fun of other people. They point out the good and they point out the
failures in a way that is simply to prevent others making the same mistakes. This is
a characteristic of a good technology, whether it is in medicine, study itself, or
basketball. It has this about it. It is humble and wishes only to serve and help man,
not in the spirit of sacrifice, but in the spirit of having fun, enjoying life. Like most
people really are when they are being themselves..,.

We All Still Love You Harry
Ed Sharp grooves Bill in
"I'm going to have to cover a lot of ground very quickly William. We simply haven't enough
time to waltz around what's been going on or why we believe it's as we think it is." Ed Sharp
had a slightly reddened complexion, almost like he'd just returned from a few days fishing. He
took a couple of quick breaths and got right back into the 'machine gun' rat a tat he started
with.
"Harry Adelman has apparently make good on his thesis and work about holographic
living transport. Either that, or he's doing a great job at pretending he did. If he was off on
some desert island, playing around, who would care? But, when people start to disappear -
not just any people - but when beautiful movie stars and four of the highest dollar models in
this world just zip out without a hint or a word, it makes you wonder. Then, look at these
others - million dollar sports cars with attaché cases full of money - nearly completed
mansions from southern California - gone - no trace - where? - how? - tankers full of
gasoline. Bill started to laugh. "It's definitely Harry". "He always talked about it - I remember
when we were roommates at school. He'd shoot this stuff by me and I'd laugh and laugh, and
he would too. Leave him alone, he'll cool off. He would never hurt anybody, I know him. He
wouldn't."
Ed Sharp wasn't laughing though, he wasn't even smiling. He'd been with the FBI since
Vietnam, chasing draft dodgers and peaceniks - not just anybody - bomb throwers - fire
starters. Nasty people. He saw Harry as an anarchist, someone who wanted to bring down
the whole system. Injured feelings or serious losses or simply just actually crazy, he saw
people like Harry as serious threats to our society that had to be reined in and tamed like
you would a wild animal.
"Bill, I know it seems funny to you, and it is, but it can also get out of hand. He's kidnapped
these girls. Who knows what he's done with them. We need you to go in - you're his friend.
I'm sure he trusts you. Just put it to him how it affects us and assure him that it's OK - we
understand - he'll get credit for his discoveries and inventions - no harm done - assuming no
harm has been done. Return the girls - and whatever else and he'll be the national hero that
he should be. That's more or less what we need and want from you." He took a few more
breaths. "No, I won't do it".
Bill was really upset at being asked to betray his friend. "How would you feel if someone
grabbed your girlfriend, daughter, sister, for fun?" Ed looked right at him. "Not so good," Bill
answered. "He'll straighten it out - he would never hurt anyone". Bill repeated.
"We're going to set him up with another model - send her in with a note to get back to us -
and we'll take it from there - I'll be in touch."
He left as abruptly as he'd left himself in to the apartment. Bill didn't like him. "He'd already
worked out all the details, without knowing Harry or himself or Evelyn or anything at all about
the work they'd put into this, a lifetime of dreams and little pilots, deep into the night study,
and for what? He understood exactly why Harry walked out of his presentation and how he'd
felt about their snide cracks. And now this cop comes crashing through his door with his plans
to trap his best friend, right or wrong, 'the FBI gets their man'. 'It's gonna happen see'."
Bill resented Ed Sharp's attitude and his disrespect for Harry. Harry stood to be one of the
greatest scientists that ever lived. One who'd already built a system that worked, that would
revolutionize transportation on our world almost beyond belief, and being treated like a
common criminal for it. All these things flashed through his mind and he decided that if
anyone had his help here, it would be Harry..

Stumbling onto Answers
In about 2003, I had the honor of working with my former freshman chemistry teacher at the University of Pennsylvania, the Nobel prize winner, Dr. Alan MacDiarmid
Way back in 1960, when I first started at Penn, his lectures were full of interesting demonstrations as well as insights into his research then into the element silicon. I remember all that, and I remember his ideas about mankind's progress on this earth following closely along the discovery of workable materials for his use at different times in his development. Silicon, you might recall, is currently highly useful in our society as a primary material for electronic circuits, probably being used by yourself right now to read this! Interesting eh? His Nobel prize though, was for the development of conductive polymers (plastics), which we were working on at the Laboratory for Research on the Structure of Matter at the Univ. of Penna. around 2003. The School District of Philadelphia had invited science teachers to participate in a teacher outreach program and I was lucky enough that Dr. MacDiarmid introduced me to a large meeting in the auditorium as his former freshman chemistry student. I really felt great about that. We worked on a paste that would help damaged nerve tissue regrow. It simply needs to conduct electricity see, otherwise it simply wouldn't regrow. The hope was that Dr. MacDiarmid's material would help it along. He passed on in 2007, i believe, may his memory be a blessing, and I read earlier that there had been some measure of success in nervous tissue repair. Most research takes a long time.
It's the research about research though that we're doing here, and the relationship of the need for answers as well as methods to success in finding valid solutions to problems. Do we just stumble onto answers? The "eureka" method. "I dreamt i was fighting a huge covid-19 motecule and my tears killed it - the next day - I thought - Yes! - salt water - tried it and it worked - wiped out the entire jar of these viruses! - or - do we employ more logical methods - like - things that worked in the past: "My mom always gave us chicken soup and told us to dress warm" - which does work often you know! What's important here is that the entire world has received over 300 million shots of 99% proven workable vaccine so far - starting from scratch less than a year ago - and already touching the "R" (reproductive) number of less than one - means it's all over for the covid-19 virus. This is an amazing result. It's like "we'll put a man on the moon by the end of the decade" - and we did; We sure did...RIP JFK. Mankind certainly has enemies - all kinds...

I worked several years counselling people for all kinds of things. Unwanted problems, upsets, attitudes - you name it. Many study problems as well. One of the things you learn when you help other people effectively, is how incredibly bright people actually are. I learned this as a high school teacher too - very early on. Kids are smart. Here's a tip: "you're stuck on some problem, don't know what to do? - ask someone - they'll tell you what it is." The human search engine is out there just waiting to be used.
