laser

The laser level creates a perfect horizontal line that can be used to line up cabinets or tile, but it is also easy read on a surveying rod.

Then they got the lasers everywhere.

We could create giant solar collectors powering a huge array of laser beams, that heat up the atmosphere so much that it is blasted into space.

Here’s the thing: I really like lasers.

I welded up a custom-branded column and and baseplate that was laser-cut by my friends at Send-Cut-Send to show you how this works.

So the laser, the transistor, LEDs, the integrated circuits, the microchip, the computer, GPS, smartphones, the internet, almost all of our modern technology that we use today that relies on electronics is thanks to developing quantum mechanics.

We have sensors underneath the bot, that mean that every time it passes over one of the squares on the grid, it has a laser underneath it, that can tell when it moves over that cell.
