One of many quietest revolutions of our present century has been the entry of quantum mechanics into our on a regular basis expertise. It was that quantum results had been confined to physics laboratories and delicate experiments. However trendy expertise more and more depends on quantum mechanics for its primary operation, and the significance of quantum results will solely develop within the many years to come back. As such, physicist Miguel F. Morales has taken on the herculean job of explaining quantum mechanics to the remainder of us laymen on this seven-part collection (no math, we promise). Under is the third story within the collection, however you may at all times discover the beginning story right here.

To date, we’ve seen particles transfer as waves and discovered {that a} single particle can take a number of, broadly separated paths. There are a variety of questions that naturally arises from this habits—one in every of them being, “How huge is a particle?” The reply is remarkably delicate, and over the subsequent two weeks (and articles) we’ll discover completely different elements of this query.

Right now, we’ll begin with a seemingly easy query: “How lengthy is a particle?”

One of many quietest revolutions of our present century has been the entry of quantum mechanics into our on a regular basis expertise. It was that quantum results had been confined to physics laboratories and delicate experiments. However trendy expertise more and more depends on quantum mechanics for its fundamental operation, and the significance of quantum results will solely develop within the many years to come back. As such, physicist Miguel F. Morales has taken on the herculean process of explaining quantum mechanics to the remainder of us laymen on this seven-part sequence (no math, we promise). Beneath is the second story within the sequence, however you possibly can all the time discover the beginning story right here.

Welcome again for our second guided stroll into the quantum mechanical woods! Final week, we noticed how particles transfer like waves and hit like particles and the way a single particle takes a number of paths. Whereas shocking, this can be a well-explored space of quantum mechanics—it’s on the paved nature path across the customer’s middle.

This week I’d prefer to get off the paved path and go a bit deeper into the woods with the intention to speak about how particles meld and mix whereas in movement. It is a matter that’s often reserved for physics majors; it is hardly ever mentioned in widespread articles. However the payoff is knowing how precision lidar works and attending to see one of many nice innovations making it out of the lab, the optical comb. So let’s go get our (quantum) mountain climbing boots a bit soiled—it will be price it.

Some technical revolutions enter with drama and a bang, others wriggle unnoticed into our on a regular basis expertise. And one of many quietest revolutions of our present century has been the entry of quantum mechanics into our on a regular basis know-how. It was that quantum results have been confined to physics laboratories and delicate experiments. However fashionable know-how more and more depends on quantum mechanics for its primary operation, and the significance of quantum results will solely develop within the a long time to come back.

As such, the time has come to clarify quantum mechanics—or, at the very least, its fundamentals.

My aim on this seven(!)-part sequence is to introduce the unusually stunning results of quantum mechanics and clarify how they’ve come to affect our on a regular basis world. Every version will embrace a guided hike into the quantum mechanical woods the place we’ll admire a brand new—and infrequently stunning—impact. As soon as again on the customer’s middle, we’ll discuss how that impact is utilized in know-how and the place to search for it.
