Nikola Tesla Chapter 1 is in the can

Tesla radio stained glass window“In the can” in the sense of wrapping up a film, as opposed to in the circular filing cabinet (or worse, the room with a view of the bidet).  Just wanted to clarify that.  In any case, with a September 1st deadline to deliver the Nikola Tesla book to the publisher I have to finish a chapter a week for the next two months.  Chapter 1 – A Scientific Rock Star is Born –  is now done.

“Done,” of course, doesn’t mean actually done.  I will still need to do significant editing, pull out sidebar quotes (it will be a very visually appealing book), and obtain the photos to be used.  But the substance is complete.

And Chapter 1 isn’t the only part of the book that is written.  I recently completed a short preface that sets the stage for Tesla’s contributions, peculiarities, and legacies.  I also have pieces of other chapters, an appendix, and ideas for how to incorporate some of his writings.

Next step is to scope out Chapter 2 – Coming of Age in Europe.  By this time next week I hope to be putting the finishing touches on the chapter. Wish me luck.

BTW, the photo is of a stained glass window in the Passage Světozor (a shopping mall) in Prague, Czech Republic. Courtesy of Wiki Commons.

I Walked 77 Miles Through Italy – For This?

I recently returned from a well-deserved (at least in my mind) trip to Italy, during which my total walking mileage was about 77 miles. In 9 days. The trip started in Rome, passed through Pisa, flourished in Florence, broke in Bologna, and mingled in Milan before coming to a close in Geneva.  And in those places there was the Sistine Chapel, the leaning tower, the naked David statue (another David, no relation), the two towers (no, not the Tolkien ones), the Last Supper, and a mostly not spurting jet d’eau. Oh, and then there was the guy who picked my pocket.

But I’m not going to talk about those now.  I’m going to talk about the weirdos.

There are weirdos in Italy.  Did you know that? To be honest I really shouldn’t be shocked given that I’ve seen this sort of thing everywhere I’ve gone in Europe (not so much in Asia for some reason).  Mostly they are the street performers, if you can call sitting or standing with no movement performing.

First there was the guy sitting on the corner of piazza that keeps Trevi Fountain from running down the street. I think he went by the name of Ronnie Raygun.

Nearby was a slightly lost Praetorian Guard.  I believe, but cannot confirm, that he was checking the GPS app on his iPhone to locate the colosseum (two miles east).

Not to be outdone was this finely dressed gentleman.  Something strange about him – Not quite sure I can see what it is though.  I think he’s hiding something.

This guy isn’t really a weirdo. In fact, he played the most extraordinary guitar.  On a most extraordinary guitar.  Very talented and a real treat to hear.

Now this guy – he was weird.  But environmentally friendly!

The Tree Man

Even the horses got into the act.  Now I know what they mean by that old expression – “tying on a feedbag.”

Too bad we can’t teach the folks here in DC how to wear a costume and stand still for hours.  They would make a lot more money begging that way.

So this was my weirdo, er, street performer post for Italy.  I assure you that there were a lot of incredible sites along the way and I’ll definitely come back to share them with you all soon.  Here’s some art to whet your appetite. Anyone know who this is (who they are)?

Nikola Tesla – A Life Lived and Died

Nikola TeslaAs the Nikola Tesla: The Wizard of Electricity book slowly springs to life (and sometimes to a life of its own), it became necessary to put together a rolling timeline of major events from birth to death.  Tesla’s life, of course, is interwoven with other key players in the development of alternating current, radio, wireless transmission, remote control guided weapons, and a few other exciting inventions to be named later.  As the timeline develops I’ll add some of the peculiar oddities that Tesla engaged in, as well as non-inventor folks like Mark Twain and Robert Underwood Johnson, but for now the following hints at some of the key scientific events.

Nikola Tesla is Born, Danilo Tesla is Killed – Who is Nikola Tesla?

As my book on Tesla: The Wizard of Electricity slowly took shape, the question was begged – Who is Nikola Tesla? Of course, you’ll have to buy the book to find out all the interesting history of the man, but here’s a teaser to get you started. Nikola begins his life, and his brother loses his life.

Born in the small village of Smiljan in what was then the Austrian Empire but now is part of present day Croatia, Tesla was born “precisely at midnight” as July 9th rolled into July 10th in 1856. This led to some uncertainty as to what date his birthday should be celebrated, but in practice his birthdays rarely were celebrated much at all, at least until his later years when he was world famous.  Then his birthdays became celebrated affairs complete with press coverage. But that was much later.  For now the young Nikola lived the rather mundane life of the son of a Serbian Orthodox priest.

The fourth of five children, Nikola became the only male heir after the rather mysterious death of his older brother, Danilo. As Tesla later tells it, Danilo met his end at the hands, or rather the hoofs, of the family horse. The horse itself had actually been a favorite of the Tesla family as it had supposedly “saved my father’s life under remarkable circumstances.” A “magnificent” Arabian breed, Telsa relates the story:

“My father had been called one winter night to perform an urgent duty and while crossing the mountains, infested by wolves, the horse became frightened and ran away, throwing him violently to the ground. It arrived home bleeding and exhausted, but after the alarm was sounded immediately dashed off again, returning to the spot, and before the searching party were far on the way they were met by my father, who had recovered consciousness and remounted, not realizing he had been lying in the snow for several hours.”

And so his father was saved by the horse. Brother Danilo was not so lucky. Again according to Tesla, “this horse was responsible for my brother’s injuries from which he died.” Worse yet, young Nikola “witnessed the tragic scene” and the “visual impression of it has lost none of its force” over the 50+ years that had elapsed.

Others suggest that Nikola may not have been such an innocent bystander.

Elephants and Tigers and Gibbons – A Trek in Khao Yai Thailand

Asia has always fascinated me.  A visit to Bangkok – before the recent flooding – was a view into a congested urban scene rivaling any of the large cities I have seen around the world. But there are relatively pristine areas as well. A short distance on the map of Thailand – only a two to three hour drive outside Bangkok toward the Cambodian border – is Khao Yai National Park. Khao Yai covers over 2000 square kilometers and includes protected forest, jungle, mountain and grassland habitat. There are also several mountains of around 1000 meters including the magnificent Khao Khieo (Green Hill).

The park is, in a word, amazing.  It plays host to almost 2,500 plant species, 67 different kinds of mammals and over 300 species of birds. The abundant wildlife includes many endangered mammals such as elephants, gibbons, tigers, leopards and Malaysian sun bears. On a drive through the park on the main road you start to notice that many of the trees and man-made structures (sign posts, concrete road safety posts) are wrapped in barbed wire to protect them from the wild elephants roaming freely around the park. Still, many of the concrete posts have been pushed over by the elephants. No tigers or bears were observed on my visit, but some magnificently colored birds and packs of gibbons were frequently seen.

The park is crisscrossed by hiking trails, ranging in length from one and a half to eight kilometers. A fairly short hike took me through the forest to a small stream. After having my photo taken on a rock overlooking what appeared to be a small precipice, I made a very steep hike down to the base of what turned out to be the tallest and most spectacular waterfall in the park. At about 250 feet high, Haew Narok falls is quite impressive (note in the photo below the spot I was standing on above is the flat rock on the top left).

My visit took place during the Thai winter (where 90°F is considered “cool”) and thus the water overflowing the falls was fairly timid. In contrast, park rangers were forced to build massive concrete pilings in the woods to keep elephants away during the rainy season when the water rages down the river and over the falls. Prior to building the pilings, 8 full grown elephants in one night alone were swept over the Haew Narok falls to their deaths.

Just outside the park, I was able to see the elephants close up. Heading for Pakchong Creek, I climbed aboard an adult female elephant for a nearly hour-long trek through the local forest. I rode for a while on a two-person carrier on the back of the elephant as my trusted mahout (driver) guided the elephant through the underbrush. But then it was my turn as the mahout dismounted and I moved down onto the neck of the elephant to guide us the rest of the way through creeks and forest.

From an environmental perspective, the trek through Khao Yai Park and the elephant ride was both heartwarming and disheartening. Tourism has now passed rice production as the biggest contributor to the economy. This increase in foreign visitors brings a broader appreciation for the ecological value of the country. But it also increases the physical demands on delicate ecosystems as more and more people descend on the park, much like the excessive tourist visits to Yellowstone and other American national parks have put a severe strain on the natural habitats, flora and fauna endemic to the regions. It is clear that Bangkok and Thailand must be aware of the environmental and human health ramifications of their continued growth.

Having said that – I can’t wait to go again.
