Pendulum WavesFifteen uncoupled simple pendulums of monotonically increasing lengths dance together to produce visual traveling waves, standing waves, beating, and (seemingly) random motion. For more details see sciencedemonstrations.fas.harvard.edu/icb/icb.do?keyword=k16940&pa... The period of one complete cycle of the dance is 60 seconds. The length of the longest pendulum has been adjusted so that it executes 51 oscillations in this 60 second period. The length of each successive shorter pendulum is carefully adjusted so that it executes one additional oscillation in this period. Thus, the 15th pendulum (shortest) undergoes 65 oscillations. Our apparatus was built from a design published by Richard Berg [Am J Phys 59(2), 186-187 (1991)] at the University of Maryland. The particular apparatus shown here was built by our own Nils Sorensen.

It's an Oregon Balloon Wine 22oz. (made in Slovakia) from our local Crate & Barrel. It seems to respond really well to 454.72 Hz, with the lip moving at a pretty good amplitude...maybe it's hitting the speaker enclosure? Anyway, take off your headphones and enjoy watching the oscillations under the strobe light! For more details on our setup see: sciencedemonstrations.fas.harvard.edu/icb/icb.do?keyword=k16940&pa...

Ieri in SF-uri, astazi la tine acasa! 650.000 RON pentru JETLEV FLYER, mai ceva ca jetpackurile din filmele cu super-eroi! Vezi video!e-redus.ro/oferta/527produsul in sine mi se pare super interesant si distractiv ;D dar ce ma amuza pe mine e ca ei vorbesc despre produsul asta ca si cum ar fi unul cu un pret destul de normal: "Poti cumpara oricate vouchere doresti", "Trasport GRATUIT oriunde in tara", dar cea mai tare mi se pare chiar la inceput unde arata pretul: "Doar: 650000lei" sunt aproape 150 de mii de euro...mi se pare mult prea mult

The Pirate Cloud" So, first we ditched the trackers. Then we got rid of the torrents. Now? Now we've gotten rid of the servers. Slowly and steadily we are getting rid of our earthly form and ascending into the next stage, the cloud. The cloud, or Brahman as the hindus call it, is the All, surrounding everything. It is everywhere; immaterial, yet very real. If there is data, there is The Pirate Bay. Our data flows around in thousands of clouds, in deeply encrypted forms, ready to be used when necessary. Earth bound nodes that transform the data are as deeply encrypted and reboot into a deadlock if not used for 8 hours. All attempts to attack The Pirate Bay from now on is an attack on everything and nothing. The site that you're at will still be here, for as long as we want it to. Only in a higher form of being. A reality to us. A ghost to those who wish to harm us. Adapt or be forever forgotten beneath the veils of maya. " thepiratebay.se/blog/224______________________________________ Printre cele mai tari chestii pe care le-am citit vreodata... Mi-a creat un sentiment profund de satisfactie... ;D
