JEDA

Suatu ketika telinga butuh jeda dari bising dunia, dari suara-suara tanpa nada dan kata yang kehilangan makna. Layaknya malam, yang sejenak sembunyi dari hiruk pikuk siang, terik yang menyengat.  Berhentilah bersuara, berteriak, memaki, mengeluh, menghakimi, agar tenang sekejap dan angin memanjakan telinga.  Dan dunia tidak harus selalu dihiasi oleh suara sumbangmu. Maka berhentilah berbicara, untuk mendengarkan dunia. 

Newton's cradle five-ball pendulum (office toy - I)

It just arrived safely this very morning, my Newton's cradle, which I bought like a month ago on eBay. It had been a while I wanted to have it on my desk. So one day, I browsed to see if there was any online shop selling the stuff. And there were a lot! 

I stumbled upon a very good offer on eBay for a small design of Newton's cradle five-ball pendulum, and it was free shipping. So, within a minute the colliding balls, which was named after the English physicist Sir Isaac Newton, was already on my shopping chart. 

I always wonder how this simple design, five small balls suspended by thin threads attached to two horizontal bars, works. I keep pulling one or two or three balls then release them and watch them rock back and forth.
