President Obama will be receiving an unusual gift during his trip to Israel.
According to New York Magazine’s Daily Intelligencer, Prime Minister Netanyahu commissioned scientists at Technion’s Russell Berrie Nanotechnology Institute to inscribe the US and Israel’s Declarations of Independence side by side on a “golden-coated silicon chip.” The inscriptions measure a grand total of 0.04 square millimeters, and run 20 nanometers, or 0.00002 mm, deep.
Impressed? Well, that’s not all.
The chip was set on a Jerusalem stone dating back to the Second Temple Period (1st century BCE to 1st century CE). It’s nearly 2,000 years old.
The etching was done by “accelerating charged atoms, called ions, and bombarding them at various points on the surface of the chip,” a press release by Technion explained. “When an ion beam hits the chip it creates a tiny recess, in this case 20 nanometers deep.”
The preparation process took about a week, but the actual engraving took less than an hour, the statement added.
The final image etched into the chip is made up of over a million dots.
Top that.
Watch Technion scientists explain exactly how the gift was made:

At a time when other newsrooms are closing or cutting back, the Forward has removed its paywall and invested additional resources to report on the ground from Israel and around the U.S. on the impact of the war, rising antisemitism and polarized discourse.
Readers like you make it all possible. We’ve started our Passover Fundraising Drive, and we need 1,800 readers like you to step up to support the Forward by April 21. Members of the Forward board are even matching the first 1,000 gifts, up to $70,000.
