Honoring Nikola Tesla's Birthday 10 July 1856-2019

Serbian-American physicist engineer and inventor Nikola Tesla is nowadays famous for his work on electricity and energy.

He developed the alternating current system, making it possible to transmit electricity over vast distances, and worked on wireless communication and energy transfer. He was a brilliant, but also very eccentric thinker, claiming to get visions and displaying odd behaviour in public like an obsession with personal hygiene and pigeons. Maybe the more enigmatic parts of his personality make him such an interesting subject for conspiracy theories. Tesla is credited to have worked on unknown energy-sources, caused the Tunguska explosion with his "death-ray" prototype, and supposedly worked on an earthquake-generator.

In 1896 Tesla was working on oscillations for wireless energy transfer. The idea was to build a steam-powered oscillator, able to create various changing frequencies. If the frequency matched the resonance frequency of a receiving device, this device should transform the mechanical oscillations back into an electric current.

In 1897 the device was ready and in 1898 Tesla supposedly managed to oscillate his laboratory at 48 E. Houston St., New York, enough, that alarmed neighbors called the police and ambulance, fearing an earthquake happening. Tesla later explained the principle to reporter Allan L. Besnson, who in February 1912 published an article about Tesla's resonator in The World Today magazine:

"He put his little vibrator in his coat-pocket and went out to hunt a half-erected steel building. Down in the Wall Street district, he found one, ten stories of steel framework without a brick or a stone laid around it. He clamped the vibrator to one of the beams, and fussed with the adjustment until he got it. Tesla said finally the structure began to creak and weave and the steel-workers came to the ground panic-stricken, believing that there had been an earthquake. Police was called out. Tesla put the vibrator in his pocket and went away. Ten minutes more and he could have laid the building in the street. And, with the same vibrator, he could have dropped the Brooklyn Bridge into the East River in less than an hour."

The "earthquake-generator" could also be used for more peaceful applications. Tesla imagined an array of smaller devices distributed all over the planet to relieve energy from Earth and also to send energy from one spot to another. A transmitter, a device consisting of a piston vibrating inside a cylinder, transforms electric energy into vibrations. Using the rocks in the underground as sort of conductor, the vibrations are sent to a receiving device and the oscillations transformed back into electricity, to be used locally. However, the "telegeodynamics" system by Tesla never managed to get beyond the prototype. In reality, the device was not powerful enough to send energy through Earth. Dampening of the oscillations by structures and the underground was far too strong.

Another vision by Tesla was more successful. He imagined using the oscillations generated by his device to study Earth. Seismic waves generated by an oscillator and projected into the underground are reflected back to a receiver by faults or different layers of rocks. Studying the reflected waves, geologists may be able to X-ray Earth (Tesla also made important contributions to modern X-ray technology). Modern seismologists still use this principle. Pulses of energy, generated by electromagnetic devices, controlled explosions or mechanical pistons, are sent deep into the underground. Geophones record the reflected signals and geologists use the collected data to generate a model of the geological structures hidden beneath the surface.

Vaso Ćuković

Najveći bokeljski dobrotvor svih vremena

Vaso Ćuković je rođen u Risnu, 09. jula 1858. g. od oca Lazara i majke Stane, u uglednoj trgovačkoj porodici, sa osmoro djece. Volio je školu, kao mlad pomagao ocu u trgovinu, i izučio zanat u Risnu, ali, nemirrnog duha, već sa 12 godina je otputovao kod tetka u Trst, koji je takođe bio trgovac U Trstu je završio višu trgovačku školu i odlično savladao grčki i italijanski jezik. Sa 16 godina se zaposlio u, tada poznatoj, grčkoj firmi "Hydias" kao činovnik. 1877. godine je, na nagovor jednog pomorskog kapetana iz Risna, kojeg je sreo u Trstu, otplovio za daleku Ameriku. Prvo u Njujork, pa San Francisko gdje je imao namjeru da se bavi trgovinom. U početku je to išlo veoma teško. Radeći svakojake poslove, učeći jezik , put ga je odveo u Nevadu, grad Reno, gdje mu je živio rođak, koji ga je pomogao sa 100 USD, što mu je bilo dovoljno, da započne samostalo, malu trgovinu. Ni tu nije uspio. U gradu Virginia Sity je radio kao prevodilac. U Virginiji, Neveda, je pokušao da radi sa rudnicima, bezuspješno, a radio je poslove čistača u jednoj bilijarnici, gdje se i upoznao sa kockarskim igrama.  Lutalačka težnja ga odvodi na kratko na Aljasku, a konačno, 1895. g. stiže je u Denver, Colorado. Tu kupuje zemlju, nastavlja trgovinu, otvara tada poznate kockarnice i za kratko vrijeme stiče veći kapital. Zahvaljujući svojim sposobnostima i inteligenciji Vaso Ćuković postaje u to vrijeme jedan od najuglednijih i najuticajnijih ličnosti grada Denvera.  Žrtvujući svoja materijalna sredstva učestvuje u izgradnji i uljepšavanju grada, pomaže razne humane akcije i učestvuje u javnom i političkom životu.

An Unconventional Handbook of Orthodox Theology

by Rev. Vladan Perisic

Foreword
by Fr John Behr

It is a great pleasure to see this work published, making available some of the most important writings of Fr Vladan Perisic over the last couple of decades available, together in one volume, to an English speaking audience. Fr Vladan’s work is well known in Serbia, and in broader academic and ecumenical circles. But it can now receive the much wider readership that it deserves, and, as a collected volume, its scope, coherence, and significance is sure to receive the recognition it deserves.

The eighteen essays collected here treat diverse topics, from academic theology (and its place in the Church) to questions of life and death, from historically oriented studies, on Sts Ignatius and Gregory Palamas, to contemporary issues, such as human rights and ecology. Each of them is characterized by meticulous scholarship and great insight, clarity of thought and expression.
