  • The Mission Continues

    As in the past so it remains today - we were and still are under the selfsame commitment to adhere to the directions of the Gedolei Yisrael, who stand guard against breaches of purity threatening our camp. When we were required to ask – we asked. When we were instructed to depart – we left. The moment we are summoned back to raise the flag, every other consideration is pushed to the side and we answer: We are ready!

Not in Heaven

Nanotechnology allows the ability to write on areas that are smaller than the eye can see.

In ancient times, Hillel taught the whole Torah to the gentile who wished to convert while standing on one foot.

In our times of advanced technology, Professor Uri Sivan, who heads the Institute of Technology at the Technion in Haifa, together with his co-workers, succeeded in writing the whole Bible on a 0.5 millimeter silicon surface.

The technology that made the writing of 304,901 words on a microscopic surface area possible is called nanotechnology. The concept stems from the word nanometer, equaling one milliardth of a millimeter. This technology enables full control over single atoms, and allows the miniaturizing of objects, documents, electronic files, and more.

The process of writing the tiny Bible involved directing a focused laser beam consisting of ions (atoms in which the amounts of electrons and protons are unequal, thus causing them to be electrically charged) to a gold-coated silicon ball.
The laser hit the gold-coated silicon surface with dots of 40 nanometers in diameter, consequently removing the gold layer and revealing the darker silicon layer. When the script was enlarged 10,000 times, the letters could be seen clearly.
The concept of nanotechnology was allegedly introduced to the public in 1986\5746 by Arik Dressler, who published a book on the topic.

Others claim that it was Professor Norio Taniguchi of Tokyo Science University who presented the concept in 1974.
The writing of the miniature Bible was registered in the Guinness World Records.
