Ok mi-a dispărut de pe fb o postare destul de recentă, în jur de acu o săptămână așa că o voi scrie din nou aici, probabil nu chiar cuvânt cu cuvânt cum a fost fiindcă nu am altă copie. (din istoria browser-ului am aflat data și ora când am postat, adică februarie, 24 ora 10 pm PDT (ora locală), adică 8 dimineață, februarie, 25 ora României.
Deci începeam cu întrebarea, ce-ar fi dacă Newton nu ne-a spus chiar tot ce i-a trecut sau picat în cap atunci. Și ca exemplu, o instalație care s-ar părea că nu respectă legea conservării momentului. Bine LOL pe vremea lui nu existau compresoare sau freon.
Deci voi recurge la descriere fiindcă nu am la îndemână și nu am mai folosit demult vreun program ca AutoCAD sau ceva asemănător.
Un tub de diametrul mare în care putem punem freon sub formă de gaz și în parale o țeavă de retur mult mai subțire unde vom avea freon lichid, amândouă legate la cele două capete. Într-unul din punctele de legătură instalăm un compresor ca cel de la un frigider iar la celălalt o supapă care să permită destinderea freonului lichid, de asemena exact ca la un frigider cu compresor. Deci practic instalația copiază design-ul unui frigider, dar cu un tub în loc de radiator, cu un circuit închis de freon unde într-un sens freonul va circula sub formă de gaz iar în sens opus sub formă de lichid. Pentru scopul demonstrației de mai jos vom neglija însă efectele termice.
Calculăm dimensiunile tubului, țevii, supapa și compresorul în așa fel încât după umplerea țevii cu freon lichid și a tubului cu freon gazos și pornirea pompei să avem aproximativ aceeași masă de freon (volumul va fi mult diferit) în tub (gaz) și în țeavă (lichid) și o circulație continuă.
La destinderea freonului prin supapă în tub freonul va căpăta viteze apropiate de cele ale sunetului, iar la comprimare la celălalt capăt viteza freonului lichid prin țeavă va fi mult mai mică. Însă după cum am spus mai sus, masele vor fi egale sau apropiate.
Deci ce se întâmplă cu diferența de moment între freonul gazos și cel lichid, dacă masele sunt aproximativ egale dar vitezele sunt atât de diferite?
În mod similar dacă realizăm un circuit electronic format dintr-un tub și o baterie. Pe porțiunea cu conductor și baterie curentul electric circulă cu viteze foarte mici. Dar între electrozi, în vid circulația curentului se plasează în 10% și mai mult din viteza luminii. Pe lângă un efect similar cu cel descris mai sus mai avem și creșterea masei prezisă de teoria relativății (și un mijloc practic de a o testa).
Viteza electronilor în funcție de diferența de potențial într-un tub vidat:
http://www.vias.org/basicradio/basic_radio_02_03.html
Și în funcție de curent într-un conductor:
"Therefore in this wire the electrons are flowing at the rate of −0.0000028 m/s."

Actors and Me
Incomplete list of actors and celebrities i possibly and unknowingly interacted with since 1995 when i came in the US and before. I would try to avoid the real big names of important persons.
1995:
Ahmet Ertegun as pastor Aurel Popescu (there are other two Aurel Popescu in the US).
Van Morrison (i forgot the Romanian name, at Aurel Popescu's Church) Might have been my classmate in Romania at Tehnoton HS, 75-78 and as Mihai and in college as Mihai Ursachi. .
Malin Bergrren as Mălina Mladin
John F Kennedy Jr. as Tom Barwik (My boss at Sheridan Fruit September 1995 - January 1996)
Liviu Dragnea as Liviu Gorea also my boss at Sheridan (every body was my boss in there and any other job)
Robin Williams as Mircea (Adrian's father) at Sheridan
Mary Sladek from NASA, wife of Vladimir Tismăneanu, as the "tall californian blonde".
Dennis Weaver (Sherrif McCloud) as Sandy, the security guy at Sheridan
many others.
1996
Prince, as Bill Apel at Credence (now LTX, in a building separated from the others).
Sir Tim Berners-Lee as Lyle Hall, at Credence.
others
1997
Sinéad O'Connor as Holly at Epson Portland Incorporated (i might have met her in Romania at Tehnoton High Shcool in Iasi). Worked 5 months next to her on a printers' assembly line.
Tom Cruise as David Higgins at Beaverton Nazarene Church across the street from Sussex, Beaverton, my mechanic until 2002
Meatloaf as pastor Dennis Swift, the same church
Leslie Nielsen (Naked Gun) as Ron Boger, the church
Don S. Davies, (Lieutenant General George Hammond, Stargate Atlantis) at Les Schwab Aloha.
Van Morrison again as assistant manager McCracken.
Jason Donovan as Jason.
Still don't know who was Bill the manager but he was also looking like a classmate from Tehnoton, Viorel Rusu.
Iulian's father (still can't decide who Iulian is, possibly Bill Gates or a lookalike), Richard Rockefeller. I might have met him in Romania, at a wedding in 1980, in Roman, Romania, (with Monica Belluci and Joan Jett, my ex HS classmates) at the Liberal Party in Bacău as Popescu in early 90s, just before i left, when i got from him Iulian's address, and also here, once in Salem at Iulian's house and this year at the Exhaust Specialties & Brakes in Tualatin, together with David Bowie though in different days.
1998
Andy Carson, channel 12 anchor, as my manager at Softlink (Qaudramed).
Tina Fey, as one of the secretaries, the same job.
Cameron Diaz, yet another secretary.
Macy Gray, yet another secretary (she got the name of her hit Try from my first programs in Delphi and also me complaining of breathing problems).
Peter O'Tool as another manager, Tom Allen.
1999
Axl Rose, as my manager at AVX, Orvile Oster (note that Oster is an anagram of Roset)
Omar Sharif, as Pat Shaffer, another tech there.
A couple of guys from the military, now dead.
Don Henley, as tech Dan Lumbert.
Nino d'Angelo as Tudor Toader.
2002
Harrison Ford as dr.Kenneth Erickson (psychiatry) at Woodland Park Hospital. The hospital closed in
2004 for many years and reopened under different name and ownership
2003 Tudor Aaron Istodor as Cristi Aniței, in Portland and his apartment in Seattle.
2004
John Travolta? or a lookalike as Timotei Mitrofan, my ex HS class mate, now director of Bible League, on Luigi Cazzavillan str, Bucharest (not sure about the address).
Roger Vadim, as ing.geolog Emil Rusu, i knew him since Câmpulung.
Can't remember exactly when Christine McVie from Fleetwood Mac became manager at Sussex Village Apts @2000. Together with Carole King, both under their real name, Christine and Caroline, Caroline being there until i left in 2010. I was seing them almost daily from my kitchen window doing their job duties. Time period for both corresponds with their carriers' hiatuses.
Servando "La Tuta" Gomez, one of my neighbors. He had a red Toyota parked next to our place in the covered car ports.
Maya Morgenstern, as Cristina Botez. Probably my condo neighbor Violeta in Bacău, Romania. Met her on and off until i started to realize who she might be @2008.
Iceland born actor and producer Sigurjón Sighvatsson as dr.Sigurtson (psychiatry) at Providence St.Vincent.
2005 was the year she moved from next door at Sussex? Winona Rider, who is actually blonde.
It was around that time i met Cornelia, the new wife of Tudor Toader. I saw them both at both Romanian Churches in Portland, she might have been Angela Gheorghiu or Elena Udrea.
Richard Branson as Richard Breunissen, counselor at OVRS (Oregon Vocational Rehabilitation then located acrross the street from Harley Davidson dealership and Washington Square Mall in Tigard Oregon).
Jorge Mario Bergoglio aka Pope Francis as David Hitt, also a psychologist at OVRS. He once insisted we met in public in the newer library in Beaverton.
2010
Kelly Clarkson as Ana, my next door neighbor (Apt.9) at 47 Eagle Crest Lake Oswego, with sometimes doubles, until i left in 2015
Not sure yet who her boyfriend was, maybe David Lynch.
2013
Kanye West, my down stairs neighbor? Actually saw him once or twice.
T'Pau from Heart and Soul, my down stairs neighbor. Doubles, sometimes only one person was "manning either Apt.9 next door or six below).
Phil Knight as officer Norbert, at Lake Oswego Police department and different name at Multnomah County Sherif Department?
Nicușor Constantinescu, downstairs. He and others let the bathroom fan running for 2 years making me really sick from vibration and dust shaken from walls. There was a pipe leaking in one of the walls from my apartment and probably the one downstairs was stinking like mold. Vibration was making the leak worse, in a cycle.
2014, Petre Mircea, sound engineer, Mădălina Manole's husband? For a couple of years all the white guys living (coming and going downstairs) where using the same car and clothes, but probably totally different persons pretending to be the same.
2015.
While Angela was in Romania for a month in May-June one night i met with Taylor Swift and her really sick looking mother, not sicker than me that night, at the Walgreens store in Lake Oswego near I5. I also saw her before, sometime @ her album Red at Tryon in the parking lot and then on the trail. I also saw her mother on numerous occasions working at the self checking registers at Home Depot.
The more recent period is harder to remember as, especially at Eagle Crest, i was permanently under influence of intoxicants of all kind, starting with cat and dog poo, cantharide dust and all kinda of drugs under the form of smoke coming through walls from downstairs and next door. Sometimes to the point of passing out. There are also a lot of persons i hesitate to name because i have no choice but to interact with them.

Referendum britanic
http://www.gandul.info/international/cea-mai-lunga-zi-a-ue-statutul-special-obtinut-de-marea-britanie-dupa-negocieri-maraton-la-bruxelles-drama-a-luat-sfarsit-15080450
"Clauza privind limitarea indemnizațiilor sociale ale angajaților străini va putea fi activată oricând în următorii șapte ani, dar unui singur individ i se va putea aplica cel mult patru ani, în mod gradual."
Rezultat al unei "negocieri" care să aducă satisfacție publicului britanic. Care se simte discriminat, în condițiile în care fiecare a participat timp de decenii la finanțarea prin taxe (contribuții la pensie) a sistemului social în fața noilor veniți. De aici se vede incapacitatea, inerentă și universală a publicului larg de a se gândi la consecințele lărgite, enorme, care pot merge de la pierderea suveranității până la desființarea națiunii pe termen lung, prin rămânerea în UE. Dar asta nu va fi simțit de cei care vor merge la referendum acum, un referendum care nu se va repeta (o declară chiar cei care îl organizează, normal, pentru a liniști publicul pentru totdeauna).
E bine? E rău?
Este clar de acum pentru oricine că UE este modelată pe SUA. Dar în timp ce SUA a pornit de la niște state independente, create de imigranții inițiali, majoritari britanici, vorbitori de engleză și tributari culturii britanice, la care s-au adăugat valuri de imigranți care însă nu au schimbat anumite elemente ca limba, legislația, cultura inițială, deci omogene cultural și lingvistic, Europa este străbătută de diferențe care au mii de ani vechime.
Deja este cunoscut că engleza este lingua franca în Uniunea Europeană. Dar la fel de cunoscut este că motorul economic este Germania și Franța.
Ce nu se cunoaște de fapt de public, și asta e o rușine, în condițiile în care se merge totuși la un referendum, este cine este motorul și scopul real din spatele creării acestei uniuni și din care trebuie să se hotărască, odată pentru totdeauna dacă vor face parte sau nu .
Eu personal cred că uniunea nu va dura, dar unii vor încerca să remodeleze, în interior, granițele statelor actuale, și acesta este singurul scop. Iar britanicii probabil nu se simt afectați de aceasta. Pentru o generație sau două.

We Should Have Been
And come wise,
Able to pick our fate in the world,
Knowing our way since the primary crossroad,
Be irresponsible only in our wish to walk.
Then become younger (by walking),
Mature and strong at the gate of creation,
Passing it through and in love adolescents,
Be children at birth of our sons.
They will be then older than us, anyways,
Would teach us to talk, would rock us to sleep,
We'll disappear more and more, become small,
Like the pearl of a grape, like a pea, like a wheat seed.

Gravity and Electrical Waves
There are two types of waves they are not teaching about in school. Gravity and electrical. Both classical (Newtonian) mechanical and electricity. Gravity and purely (non electro-magnetic) electrical waves are explained by first, Newton's universal attraction law in case of gravity and attraction and repelling force in case of electrical. Very simply, if you move any mass or electrical charge it will exert a variable force towards anything else that has a mass or electrical charge in the Universe, but that force is maximum near the source.
Let's start with a simple gravity pendulum
https://en.wikipedia.org/wiki/Pendulum_(mathematics)#Simple_gravity_pendulum
For the purpose of this demonstration we will neglect the gravity force which actually moves the pendulum that manifests on the vertical. It could have been a spring or a motor or whatever and should consider only the gravity force developed by the bob m1 interacting with any other stationary bob m2 at a distance (X zero) from the center of the pendulum on the horizontal.
This could be also be proven, practically. If we placed two pendula of the same length, weight, etc. in boxes so we can eliminate any acoustic phenomena or even in vacuum and move one of them, we would see, after a while, the other starting moving, so we could be sure the only way for this to happen is through gravity waves.
