Instead of an official product review this week, Ben talks about his recent camping trip at the Grand Canyon. Of course there was a tent, sleeping bags, a camping stove … along with a few high-tech upgrades like a projector, Apple TV and a 100-inch screen attached to a canopy. It was all powered by a brand-new portable power station.

When you think of synchronization, syncing your phone with a laptop probably comes to mind. But, in science, this is an actual phenomenon that occurs in nature. This is why a bunch of metronomes will begin ticking at the same time on a platform. It’s all about synchronization.

The average human is capable of hearing frequencies between 20Hz to 20,000Hz. The higher you hear, the better your hearing ability. And the older we get, the harder it is to hear high-frequency sounds. Take this simple, accurate quiz to see how you stack up.

What is something that the military, bats and doctors all have in common? They all use sounds to see. Specifically, they use the echo from sound bouncing off objects to visualize their surroundings. So how does this technology work and what other applications may it have?

I don’t trust Big Tech and you shouldn’t, either. You’ve heard me say for years that free email services like Gmail or Yahoo aren’t really free. There’s a big price to pay — your privacy. These free email sites scan, analyze and save details of every email you send and receive, giving Big Tech a very intimate and detailed profile of you so they can easily sell your data to the highest bidder.

Don’t trust Big Tech with your data and privacy.
